  • How do I return a message if $_GET is null or does not match any database entries?

    - by CT
    I am working on designing an IT Asset database. Here I am working on a page used to view details on a specific asset determined by an asset id. Here I grab $id from $_GET["id"]; When $id is null, the page does not load. When $id does not match any entry within the database, the page loads but no asset table is printed. In both these cases, I would like to display a message like "There is no database entry for that Asset ID" How would this be handled? Thank you. <?php /* * View Asset * */ # include functions script include "functions.php"; $id = $_GET["id"]; ConnectDB(); $type = GetAssetType($id); ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <link rel="stylesheet" type="text/css" href="style.css" /> <title>Wagman IT Asset</title> </head> <body> <div id="page"> <div id="header"> <img src="images/logo.png" /> </div> </div> <div id="content"> <div id="container"> <div id="main"> <div id="menu"> <ul> <table width="100%" border="0"> <tr> <td width="15%"></td> <td width="30%%"><li><a href="index.php">Search Assets</a></li></td> <td width="30%"><li><a href="addAsset.php">Add Asset</a></li></td> <td width="25%"></td> </tr> </table> </ul> </div> <div id="text"> <ul> <li> <h1>View Asset</h1> </li> </ul> <br /> <?php switch ($type){ case "Server": $result = QueryServer($id); $ServerArray = GetServerData($result); PrintServerTable($ServerArray); break; case "Desktop"; break; case "Laptop"; break; } ?> </div> </div> </div> <div class="clear"></div> <div id="footer" align="center"> <p>&nbsp;</p> </div> </div> <div id="tagline"> Wagman Construction - Bridging Generations since 1902 </div> </body> </html>

  • jQuery: Div elements are not showing up

    - by Legend
    I am adapting the Coverflow technique to work with a div. Following is the html: <html> <head> <meta http-equiv="Content-type" content="text/html; charset=utf-8" /> <style type="text/css" media="screen"> body,html { margin: 0; padding: 0; background: #000; height: 100%; color: #eee; font-family: Arial; font-size: 10px; } div.magnifyme { height: 80px; padding: 80px; position: absolute; top: 0px; left: 0px; width: 8000px; } div.wrapper { margin: 0px; height: 470px; /*border: 2px solid #999;*/ overflow: hidden; padding-left: 40px; right: 1px; width: 824px; position: relative; } div.container {position: relative; width: 854px; height: 480px; background: #000; margin: auto;} div.nav {position: absolute; top: 10px; width: 20%; height: 10%; right: 1px; } div.magnifyme div { position: absolute; width: 300px; height: 280px; float: left; margin: 5px; position: relative; border: 2px solid #999; background: #500; } </style> <script type="text/javascript" src="jquery-1.3.2.js"></script> <script type="text/javascript" src="ui.coverflow.js"></script> <script type="text/javascript"> $(function() { $("div.magnifyme").coverflow(); $("#add").click(function() { location.reload(); $(".magnifyme").append("<div id=\"div5\">hello world</div>"); $("div.magnifyme").coverflow(); }); }); </script> </head> <body> <div class="container"> <div class="wrapper"> <div class="magnifyme"> <div id="div0">This is div 0</div> <div id="div1">This is div 1</div> <div id="div2">This is div 2</div> <div id="div3">This is div 3</div> <div id="div4">This is div 4</div> </div> </div> <div class="nav"> <button type="button" id="add">Add to Deck</button> </div> </div> </body> </html> The coverflow function (included as a js file in the head section) is here. When I click the button, I was expecting it to add a DIV to the already present deck. For some reason, it doesn't show the newly added DIV. I tried calling the coverflow() function after I added the new element but that didn't work either. Is there any way I can make this work?

  • How to write a bison grammer for WDI?

    - by Rizo
    I need some help in bison grammar construction. From my another question: I'm trying to make a meta-language for writing markup code (such as xml and html) wich can be directly embedded into C/C++ code. Here is a simple sample written in this language, I call it WDI (Web Development Interface): /* * Simple wdi/html sample source code */ #include <mySite> string name = "myName"; string toCapital(string str); html { head { title { mySiteTitle; } link(rel="stylesheet", href="style.css"); } body(id="default") { // Page content wrapper div(id="wrapper", class="some_class") { h1 { "Hello, " + toCapital(name) + "!"; } // Lists post ul(id="post_list") { for(post in posts) { li { a(href=post.getID()) { post.tilte; } } } } } } } Basically it is a C source with a user-friendly interface for html. As you can see the traditional tag-based style is substituted by C-like, with blocks delimited by curly braces. I need to build an interpreter to translate this code to html and posteriorly insert it into C, so that it can be compiled. The C part stays intact. Inside the wdi source it is not necessary to use prints, every return statement will be used for output (in printf function). The program's output will be clean html code. So, for example a heading 1 tag would be transformed like this: h1 { "Hello, " + toCapital(name) + "!"; } // would become: printf("<h1>Hello, %s!</h1>", toCapital(name)); My main goal is to create an interpreter to translate wdi source to html like this: tag(attributes) {content} = <tag attributes>content</tag> Secondly, html code returned by the interpreter has to be inserted into C code with printfs. Variables and functions that occur inside wdi should also be sorted in order to use them as printf parameters (the case of toCapital(name) in sample source). Here are my flex/bison files: id [a-zA-Z_]([a-zA-Z0-9_])* number [0-9]+ string \".*\" %% {id} { yylval.string = strdup(yytext); return(ID); } {number} { yylval.number = atoi(yytext); return(NUMBER); } {string} { yylval.string = strdup(yytext); return(STRING); } "(" { return(LPAREN); } ")" { return(RPAREN); } "{" { return(LBRACE); } "}" { return(RBRACE); } "=" { return(ASSIGN); } "," { return(COMMA); } ";" { return(SEMICOLON); } \n|\r|\f { /* ignore EOL */ } [ \t]+ { /* ignore whitespace */ } . { /* return(CCODE); Find C source */ } %% %start wdi %token LPAREN RPAREN LBRACE RBRACE ASSIGN COMMA SEMICOLON CCODE QUOTE %union { int number; char *string; } %token <string> ID STRING %token <number> NUMBER %% wdi : /* empty */ | blocks ; blocks : block | blocks block ; block : head SEMICOLON | head body ; head : ID | ID attributes ; attributes : LPAREN RPAREN | LPAREN attribute_list RPAREN ; attribute_list : attribute | attribute COMMA attribute_list ; attribute : key ASSIGN value ; key : ID {$$=$1} ; value : STRING {$$=$1} /*| NUMBER*/ /*| CCODE*/ ; body : LBRACE content RBRACE ; content : /* */ | blocks | STRING SEMICOLON | NUMBER SEMICOLON | CCODE ; %% I am having difficulties on defining a proper grammar for the language, specially in splitting WDI and C code . I just started learning language processing techniques so I need some orientation. Could someone correct my code or give some examples of what is the right way to solve this problem?

  • [BEGINNER] Javascript Pop Ups

    - by user566312
    Hey All, My boss has asked for a page that will not change to have two timed pop ups load. I have found code and edited it to what I had thought it should do, but it is only loading the last onLoad event. I am a designer and I have helped with making webpages, but Javascript is so far outside of what I can understand. I have already learned how to use the single pop up and spent a whiiile learning the timeouts, but I cannot seem to get it to work with multiple popup functions. If you have a moment, would you take a look?

  • Unable to show Desktop Notifications using Google Chrome

    - by Praveen Kumar
    I followed the instructions as given in Using The Notifications API. Also I faced many problems like the below, because I added the document.querySelector() inside the <head> part: Uncaught TypeError: Cannot call method 'addEventListener' of null Now I have the below source, where I am able to Check Notification Support, and Check Notification Permissions links. Guide me how to bring in notifications in a simpler way. Also, I tried this: $("#html").click(function() { if (window.webkitNotifications.checkPermission() == 0) { createNotificationInstance({ notificationType: 'html' }); } else { window.webkitNotifications.requestPermission(); } }); Now I am stuck with this source. I need to generate HTML & Simple Notifications. Am I missing something? Please guide me.

  • Ensuring a divs content has changed over time in Selenium

    I have a div that contains a slideshow. ( http://film.robinhoodtax.org/issues/education ) I am using Selenium to test it.

  • Trouble with client side validation using Struts 2. Xml based validation rules not recognized.

    Hi, This is my first post to ask a question on stack overflow and my issue is that when I don't see a client side validation error message when I don't enter any values for that field even when it is configured as required.

  • How to select all options from a drop list in php / mysql

    - by Mirage81
    Thanks to stackoverflow.com's frienly experts I've managed to create my first php + mysql application. The code searches a mysql database for last names and cities. The choices are made through two drop lists like these: Choose city: All cities Liverpool Manchester Choose last name: All last names Lennon Gallagher The code would return eg. all the Lennons living in Liverpool. However, I haven't been able to make the options "All cities" and "All last names" to work so that the code would return eg. all the Lennons living in any city or all the people living in Liverpool.

  • IE 6 and 7 background inheritance problem, how do I solve this?

    - by Evilalan
    When I'm trying to create a rounded shaded box it works fine on FF and IE8 but on IE6 and IE7, any div inside the box gets the last background but if you set that all divs on the level where there should not be a background have background:none it doesn't show any background on the level that comes before *The code is pointing to live images on Image Shack so you can save and run that it will work normally on Firefox but you can see what happen on IE6/7.

  • Change a dropdown depending on another dropdown

    - by Eric Evans
    I'm trying to create a three select dropdowns that represent a persons birthday. I'm taking into consideration that there are 4 months with 30 days, 7 with 31 ,and 1 with 28 or 29 depending if it's a leap year or not. I would like the days dropdown to show the number of days depending on which month is chosen in the month dropdown. Here's what I have now. Here's the html for the select <!Doctype html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Birthday validation</title> <script src="jquery-1.11.1.min.js"></script> <script src="birthday_drop.js"></script> <link href="style.css" rel="stylesheet /> </head> <body> <h2>Birthday</h2> <fieldset class="birthday-picker"> <select class="birth-month" name="birth[month]"><option>Month</option></select> <select class="birth-day" name="birth[day]"><option>Day</option></select> <select class="birth-year" name="birth[year]"><option>Year</option></select> </fieldset> </body> </html> Here's the jquery that populates the dropdowns and my attempt to use the change function /** * Created by Eric Evans on 8/19/14. */ $(document).ready(function(){ var months = ['January','February','March','April','May','June','July','August','September','October','November','December']; for(i=0; i < months.length; i++){ $("<option value=' + months[i] + '>" + months[i] + "</option>").appendTo('.birth-month'); } for(i=0; i <= 31; i++){ $("<option value=' + i + '>" + i + "</option>").appendTo('.birth-day'); } var myYear = new Date().getFullYear(); for(i=myYear; i >= 1950; i--){ $("<option value=' + i + '>" + i + "</option>").appendTo('.birth-year'); } $('.birth-month').change(function(){ if($(this).val() == 'April'){ for(i=0; i <= 30; i++){ $("<option value=' + i + '>" + i + "</option>").appendTo('.birth-day'); } } }); }); Any help would be greatly appreciated

  • Need to determine button clicked in a JQuery mobile popup and perform actions based thereon

    - by Clifford
    I am having a problem with a JQM popup. The popup has 3 buttons, and the action taken in the main program depends on which button is clicked. The code in the main program is run more than once and I am not sure why. The simple example below uses an alert to display which button on the popup was clicked. When the popup is called the first time, it works as hoped, the 2nd time, the alert is displayed twice, the 3rd time, the alert is displayed 3 times, etc. <html> <head> <meta name="viewport" content="width=device-width, initial-scale=1"> <link rel="stylesheet" href="css/jquery.mobile-1.3.2.min.css" /> <script type="text/javascript" charset="utf-8" src="cordova-2.6.0.js"></script> <script type="text/javascript" src="js/jquery-1.9.1.min.js"/></script> <script type="text/javascript" src="js/jquery.mobile-1.3.2.min.js"></script> <script> function doCustomDialog(text1,button1,button2,button3,callback) { $("#customDialog .customDialogDesc").text(text1); $("#customDialog .customDialogOption1").text(button1).on("click.customDialog", function(){ callback("option1"); }); $("#customDialog .customDialogOption2").text(button2).on("click.customDialog", function(){ callback("option2"); }); $("#customDialog .customDialogOption3").text(button3).on("click.customDialog", function(){ callback("option3"); }); $("#customDialog").popup("open"); } </script> </head> <body> <div data-role="page" id="mainPage"> <div data-role="content"> <INPUT type="button" id="confirm" value="Save data" /> <div data-role="popup" id="customDialog" data-title="Are you sure?" class="ui-content"> <p class ="customDialogDesc">???</p> <a href="#" class ="customDialogOption1" data-role="button" data-theme="b" data-rel="back">Yes</a> <a href="#" class ="customDialogOption2" data-role="button" data-theme="b" data-rel="back">No</a> <a href="#" class ="customDialogOption3" data-role="button" data-theme="b" data-rel="back">Cancel</a> </div> </div> </div> <script> $("#mainPage").on("pageshow", function(e) { $("#confirm").click(function() { doCustomDialog("A similar record already exists.

  • input field placeholder in jQuery

    - by Hristo
    I'm trying to create a Login page, not worrying about actually logging in yet, but I'm trying to achieve the effect where there is some faded text inside the input field and when you click on it, the text disappears or if you click away the text reappears. I have this working for my "Username" input field, but the "Password" field is giving me problems because I can't just do $("#password").attr("type","password"). Here's my code: <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Insert title here</title> <!-- Links --> <link rel="stylesheet" type="text/css" href="style.css" /> <!-- Scripts --> <script type="text/javascript" src="jQuery.js"></script> <script> // document script $(document).ready(function(){ // login box event handler $('#login').click(function(){ $('.loginBox').animate({ height: '150px' }, '1000' ); $('#username').show(); // add pw placeholder field $('#password').after('<input type="text" id="placeHolder" value="Password" class="placeHolder" />'); $('#password').hide(); }); // username field focus and blur event handlers $('#username').focus(function() { if($(this).hasClass('placeHolder')){ $(this).val(''); $(this).removeClass('placeHolder'); } }); $('#username').blur(function() { if($(this).val() == '') { $(this).val('Username'); $(this).addClass('placeHolder'); } }); // password field focus and blur event handlers $('#placeHolder').focus(function() { $('#placeHolder').hide(); $('#password').show(); $('#password').focus(); }); $('#password').blur(function() { if($('#password').val() == '') { $('#placeHolder').show(); $('#password').hide(); } }); }); </script> </head> <body> <div id="loginBox" class="loginBox"> <a id="login">Proceed to Login</a><br /> <div id="loginForm"> <form> <input type="text" id="username" class="placeHolder" value="Username" /> <input type="password" id="password" class="placeHolder" value="" /> </form> </div> </div> </body> </html> Right now, I can click on the password input box and type in it, but the text is not disappearing and the "type" doesn't get set to "password"... the new input field I create isn't being hidden, it just stays visible, and I'm not sure where the problem is. Any ideas? Thanks, Hristo

  • Select dropdown with fixed width cutting off content in IE

    - by aaandre
    The issue: Some of the items in the select require more than the specified width of 145px in order to display fully. Firefox behavior: clicking on the select reveals the dropdown elements list adjusted to the width of the longest element. IE6 & IE7 behavior: clicking on the select reveals the dropdown elements list restricted to 145px width making it impossible to read the longer elements. The current UI requires us to fit this dropdown in 145px and have it host items with longer descriptions. Any advise on resolving the issue with IE? The top element should remain 145px wide even when the list is expanded. Thank you! The css: select.center_pull { background:#eeeeee none repeat scroll 0 0; border:1px solid #7E7E7E; color:#333333; font-size:12px; margin-bottom:4px; margin-right:4px; margin-top:4px; width:145px; } Here's the select input code (there's no definition for the backend_dropbox style at this time) <select id="select_1" class="center_pull backend_dropbox" name="select_1"> <option value="-1" selected="selected">Browse options</option> <option value="-1">------------------------------------</option> <option value="224">Option 1</option> <option value="234">Longer title for option 2</option> <option value="242">Very long and extensively descriptive title for option 3</option> </select> Full html page in case you want to quickly test in a browser: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>dropdown test</title> <style type="text/css"> <!-- select.center_pull { background:#eeeeee none repeat scroll 0 0; border:1px solid #7E7E7E; color:#333333; font-size:12px; margin-bottom:4px; margin-right:4px; margin-top:4px; width:145px; } --> </style> </head> <body> <p>Select width test</p> <form id="form1" name="form1" method="post" action=""> <select id="select_1" class="center_pull backend_dropbox" name="select_1"> <option value="-1" selected="selected">Browse options</option> <option value="-1">------------------------------------</option> <option value="224">Option 1</option> <option value="234">Longer title for option 2</option> <option value="242">Very long and extensively descriptive title for option 3</option> </select> </form> </body> </html>

  • Handling a Long Running jsp request on the server using Ajax and threads

    - by John Blue
    I am trying to implement a solution for a long running process on the server where it is taking about 10 min to process a pdf generation request. The browser bored/timesout at the 5 mins. I was thinking to deal with this using a Ajax and threads. I am using regular javascript for ajax. But I am stuck with it. I have reached till the point where it sends the request to the servlet and the servlet starts the thread.Please see the below code public class HelloServlet extends javax.servlet.http.HttpServlet implements javax.servlet.Servlet { protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { } protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { System.out.println("POST request!!"); LongProcess longProcess = new LongProcess(); longProcess.setDaemon(true); longProcess.start(); request.getSession().setAttribute("longProcess", longProcess); request.getRequestDispatcher("index.jsp").forward(request, response); } } class LongProcess extends Thread { public void run() { System.out.println("Thread Started!!"); while (progress < 10) { try { sleep(2000); } catch (InterruptedException ignore) {} progress++; } } } Here is my AJax call <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html><head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> <title>My Title</title> <script language="JavaScript" > function getXMLObject() //XML OBJECT { var xmlHttp = false; xmlHttp = new XMLHttpRequest(); //For Mozilla, Opera Browsers return xmlHttp; // Mandatory Statement returning the ajax object created } var xmlhttp = new getXMLObject(); //xmlhttp holds the ajax object function ajaxFunction() { xmlhttp.open("GET","HelloServlet" ,true); xmlhttp.onreadystatechange = handleServerResponse; xmlhttp.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded'); xmlhttp.send(null); } function handleServerResponse() { if (xmlhttp.readyState == 4) { if(xmlhttp.status == 200) { document.forms[0].myDiv.value = xmlhttp.responseText; setTimeout(ajaxFunction(), 2000); } else { alert("Error during AJAX call. Please try again"); } } } function openPDF() { document.forms[0].method = "POST"; document.forms[0].action = "HelloServlet"; document.forms[0].submit(); } function stopAjax(){ clearInterval(intervalID); } </script> </head> <body><form name="myForm"> <table><tr><td> <INPUT TYPE="BUTTON" NAME="Download" VALUE="Download Queue ( PDF )" onclick="openPDF();"> </td></tr> <tr><td> Current status: <div id="myDiv"></div>% </td></tr></table> </form></body></html> But I dont know how to proceed further like how will the thread communicate the browser that the process has complete and how should the ajax call me made and check the status of the request. Please let me know if I am missing some pieces. Any suggestion if helpful.

    I creating a simple site with PHP where the users can submit blogs and other users (who are logged in) can post comments on them. I have made a link called "comments" below each blog that when clicked will show / hide all the comments relevant to the specific blog (also if the user is logged in, it will show a form field in which they can submit new comments). So basically each blog will have multiple comments. I have done two different codes for this but they both have the same problem that each comment appears twice (everything else works fine). Could anyone point out why? mysql_select_db ("ooze"); $result = mysql_query ("select * from blog") or die(mysql_error()); $i = 1; while($row = mysql_fetch_array($result)) { echo "<h1>$row[title]</h1>"; echo "<p class ='second'>$row[blog_content]</p> "; echo "<p class='meta'>Posted by .... &nbsp;&bull;&nbsp; $row[date] &nbsp;&bull;&nbsp; <a href='#' onclick=\"toggle_visibility('something$i'); return false\">Comments</a><div id='something$i' style='display: none;'>"; $i++; $a = $row["ID"]; $result2 = mysql_query ("select * from blog, blogcomment where $a=blogID") or die(mysql_error()); while($sub = mysql_fetch_array($result2)) { echo "<p class='third' >$sub[commentdate] &nbsp;&bull;&nbsp; $sub[username]</p><p>said:</p> <p>$sub[comment]</p>"; } if ( isset ($_SESSION["gatekeeper"])) { echo '<form method="post" name="result_'.$row["ID"].'" action="postcomment.php"><input name="ID" type = "hidden" value = "'.$row["ID"].'" /><input name="comment" id="comment" type="text" style="margin-left:20px;"/><input type="submit" value="Add comment" /></form>'; } else { echo '<p class="third"><a href="register.html">Signup </a>to post a comment</p>'; } echo "</div>"; } mysql_close($conn); //second version of inner loop:// if ( isset ($_SESSION["gatekeeper"])) { while($sub = mysql_fetch_array($result2)) { echo "<p class='third' >$sub[commentdate] &nbsp;&bull;&nbsp; $sub[username] said:</p> <p>$sub[comment]</p>"; } echo '<form method="post" name="result_'.$row["ID"].'" action="postcomment.php"><input name="ID" type = "hidden" value = "'.$row["ID"].'" /><input name="comment" id="comment" type="text" style="margin-left:20px;"/><input type="submit" value="Add comment" /></form>'; } else { while($sub = mysql_fetch_array($result2)) { echo "<p class='third' >$sub[commentdate] &nbsp;&bull;&nbsp; $sub[username] said:</p> <p>$sub[comment]</p>"; } echo '<p class="third"><a href="register.html">Signup </a>to post a comment</p>'; } echo "</div>"; } mysql_close($conn);

    - by Kostis
    I have 3 buttons on my page and depending on which one the user is clickingi want to run through ajax call a delete query in my database. When the user clicks on a button the javascript function seems to work but it doesn't run the query in php script. The html page: <?php session_start(); ?> <!DOCTYPE HTML> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-7"> <script> function myFunction(name) { var r=confirm("Are you sure?

  • PHP setting cookies in a child class

    - by steve
    I am writing a custom session handler and for the life of me I cannot get a cookie to set in it. I'm not outputting anything to the browser before I set the cookie but it still doesn't work. Its killing me. The cookie will set if I set it in the script I define and call on the session handler with. If necessary I will post code. Any ideas people? <?php /* require the needed classes comment out what is not needed */ require_once("classes/sessionmanager.php"); require_once("classes/template.php"); require_once("classes/database.php"); $title=" "; //titlebar of the web browser $description=" "; $keywords=" "; //meta keywords $menutype="default"; //default or customer, customer is elevated $pagetitle="dflsfsf "; //title of the webpage $pagebody=" "; //body of the webpage $template=template::def_instance(); $database=database::def_instance(); $session=sessionmanager::def_instance(); $session->sessions(); session_start(); ?> and this is the one that actually sets the cookie for the session function write($session_id,$session_data) { $session_id = mysql_real_escape_string($session_id); $session_data = mysql_real_escape_string(serialize($session_data)); $expires = time() + 3600; $user_ip = $_SERVER['REMOTE_ADDR']; $bol = FALSE; $time = time(); $newsession = FALSE; $auth = FALSE; $query = "SELECT * FROM 'sessions' WHERE 'expires' > '$time'"; $sessions_result = $this->query($query); $newsession = $this->newsession_check($session_id,$sessions_result); while($sessions_array = mysql_fetch_array($sessions_result) AND $auth = FALSE) { $session_array = $this->strip($session_array); $auth = $this->auth_check($session_array,$session_id); } /* this is an authentic session. build queries and update it */ if($auth = TRUE AND $newsession = FALSE) { $session_data = mysql_real_escape_string($session_data); $update_query1 = "UPDATE 'sessions' SET 'user_ip' = '$user_ip' WHERE 'session_id' = '$session_id'"; $update_query2 = "UPDATE 'sessions' SET 'data' = '$session_data' WHERE 'session_id = '$session_id'"; $update_query3 = "UPDATE 'sessions' SET 'expires' = '$expires' WHERE 'session_id' = '$session_id'"; $this->query($update_query1); $this->query($update_query2); $this->query($update_query3); $bol = TRUE; } elseif($newsession = TRUE) { /* this is a new session, build and create it */ $random_number = $this->obtain_random(); $cookieval = hash("sha512",$random_number); setcookie("rndn",$cookieval); $query = "INSERT INTO sessions VALUES('$session_id','0','$user_ip','$random_number','$session_data','$expires')"; $this->query($query); //echo $cookieval."this is the cookie <<"; $bol = TRUE; } return $bol; }

  • JSF - Random Number using Beans (JAVA)

    - by Alex Encore Tr
    I am trying to create a jsf application which, upon page refresh increments the hit counter and generates two random numbers. What should be displayed on the window may look something like this: On your On your roll x you have thrown x and x For this program I decided to create two Beans, one to hold the page refresh counter and one to generate a random number. Those look like this for the moment: CounterBean.java package diceroll; public class CounterBean { int count=0; public CounterBean() { } public void setCount(int count) { this.count=count; } public int getCount() { count++; return count; } } RandomNumberBean.java package diceroll; import java.util.Random; public class RandomNumberBean { int rand=0; Random r = new Random(); public RandomNumberBean() { rand = r.nextInt(6); } public void setNextInt(int rand) { this.rand=rand; } public int getNextInt() { return rand; } } I have then created an index.jsp to display the above message. <html> <%@ taglib uri="http://java.sun.com/jsf/core" prefix="f"%> <%@ taglib uri="http://java.sun.com/jsf/html" prefix="h"%> <f:view> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> <title>Roll the Dice</title> </head> <body> <h:form> <p> On your roll # <h:outputText value="#{CounterBean.count} " /> you have thrown <h:outputText value="#{RandomNumberBean.rand}" />and <h:outputText value="#{RandomNumberBean.rand} " /> </p> </h:form> </body> </f:view> </html> However, when I run the application, I get the following message: org.apache.jasper.el.JspPropertyNotFoundException: /index.jsp(14,20) '#{RandomNumberBean.rand}' Property 'rand' not found on type diceroll.RandomNumberBean Caused by: org.apache.jasper.el.JspPropertyNotFoundException - /index.jsp(14,20) '#{RandomNumberBean.rand}' Property 'rand' not found on type diceroll.RandomNumberBean I suppose there's a mistake with my faces-config.xml file, so I will post this here as well, see if somebody can provide some help: faces-config.xml <?xml version="1.0" encoding="UTF-8"?> <faces-config xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd" version="2.0"> <managed-bean> <managed-bean-name>CounterBean</managed-bean-name> <managed-bean-class>diceroll.CounterBean</managed-bean-class> <managed-bean-scope>session</managed-bean-scope> </managed-bean> <managed-bean> <managed-bean-name>RandomNumberBean</managed-bean-name> <managed-bean-class>diceroll.RandomNumberBean</managed-bean-class> <managed-bean-scope>session</managed-bean-scope> </managed-bean> </faces-config>
