  • Saving images only available when logged in

    - by James
    Hi, I've been having some trouble getting images to download when logged into a website that requires you to be logged in. The images can only be viewed when you are logged in to the site, but you cannot seem to view them directly in the browser if you copy its location into a tab/new window (it redirects to an error page - so I guess the containing folder has be .htaccess-ed). Anyway, the code I have below allows me to log in and grab the HTML content, which works well - but I cannot grab the images ... this is where I need help! <? // curl.php class Curl { public $cookieJar = ""; public function __construct($cookieJarFile = 'cookies.txt') { $this->cookieJar = $cookieJarFile; } function setup() { $header = array(); $header[0] = "Accept: text/xml,application/xml,application/xhtml+xml,"; $header[0] .= "text/html;q=0.9,text/plain;q=0.8,image/gif;q=0.8,image/x-bitmap;q=0.8,image/jpeg;q=0.8,image/png,*/*;q=0.5"; $header[] = "Cache-Control: max-age=0"; $header[] = "Connection: keep-alive"; $header[] = "Keep-Alive: 300"; $header[] = "Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7"; $header[] = "Accept-Language: en-us,en;q=0.5"; $header[] = "Pragma: "; // browsers keep this blank. curl_setopt($this->curl, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 5.2; en-US; rv:1.8.1.7) Gecko/20070914 Firefox/2.0.0.7'); curl_setopt($this->curl, CURLOPT_HTTPHEADER, $header); curl_setopt($this->curl, CURLOPT_COOKIEJAR, $this->cookieJar); curl_setopt($this->curl, CURLOPT_COOKIEFILE, $this->cookieJar); curl_setopt($this->curl, CURLOPT_AUTOREFERER, true); curl_setopt($this->curl, CURLOPT_FOLLOWLOCATION, true); curl_setopt($this->curl, CURLOPT_RETURNTRANSFER, true); } function get($url) { $this->curl = curl_init($url); $this->setup(); return $this->request(); } function getAll($reg, $str) { preg_match_all($reg, $str, $matches); return $matches[1]; } function postForm($url, $fields, $referer = '') { $this->curl = curl_init($url); $this->setup(); curl_setopt($this->curl, CURLOPT_URL, $url); curl_setopt($this->curl, CURLOPT_POST, 1); curl_setopt($this->curl, CURLOPT_REFERER, $referer); curl_setopt($this->curl, CURLOPT_POSTFIELDS, $fields); return $this->request(); } function getInfo($info) { $info = ($info == 'lasturl') ? curl_getinfo($this->curl, CURLINFO_EFFECTIVE_URL) : curl_getinfo($this->curl, $info); return $info; } function request() { return curl_exec($this->curl); } } ?> And below is the page that uses it. <? // data.php include('curl.php'); $curl = new Curl(); $url = "http://domain.com/login.php"; $newURL = "http://domain.com/go_here.php"; $username = "user"; $password = "pass"; $fields = "user=$username&pass=$password"; // Calling URL $referer = "http://domain.com/refering_page.php"; $html = $curl->postForm($url, $fields, $referer); $html = $curl->get($newURL); echo $html; ?> I've tried putting the direct URL for the image into $newURL but that doesn't get the image - it simply returns an error saying since that folder is not available to view directly. I've tried varying the above in different ways, but I haven't been successful in getting an image, though I have managed to get a screen through basically saying error 405 and/or 406 (but not the image I want). Any help would be great!

  • Qt 4.6 Adding objects and sub-objects to QWebView window object (C++ & Javascript)

    - by Cor
    I am working with Qt's QWebView, and have been finding lots of great uses for adding to the webkit window object. One thing I would like to do is nested objects... for instance: in Javascript I can... var api = new Object; api.os = new Object; api.os.foo = function(){} api.window = new Object(); api.window.bar = function(){} obviously in most cases this would be done through a more OO js-framework. This results in a tidy structure of: >>>api ------------------------------------------------------- - api Object {os=Object, more... } - os Object {} foo function() - win Object {} bar function() ------------------------------------------------------- Right now I'm able to extend the window object with all of the qtC++ methods and signals I need, but they all have 'seem' to have to be in a root child of "window". This is forcing me to write a js wrapper object to get the hierarchy that I want in the DOM. >>>api ------------------------------------------------------- - api Object {os=function, more... } - os_foo function() - win_bar function() ------------------------------------------------------- This is a pretty simplified example... I want objects for parameters, etc... Does anyone know of a way to pass an child object with the object that extends the WebFrame's window object? Here's some example code of how I'm adding the object: mainwindow.h #ifndef MAINWINDOW_H #define MAINWINDOW_H #include <QtGui/QMainWindow> #include <QWebFrame> #include "mainwindow.h" #include "happyapi.h" class QWebView; class QWebFrame; QT_BEGIN_NAMESPACE class MainWindow : public QMainWindow { Q_OBJECT public: MainWindow(QWidget *parent = 0); private slots: void attachWindowObject(); void bluesBros(); private: QWebView *view; HappyApi *api; QWebFrame *frame; }; #endif // MAINWINDOW_H mainwindow.cpp #include <QDebug> #include <QtGui> #include <QWebView> #include <QWebPage> #include "mainwindow.h" #include "happyapi.h" MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent) { view = new QWebView(this); view->load(QUrl("file:///Q:/example.htm")); api = new HappyApi(this); QWebPage *page = view->page(); frame = page->mainFrame(); attachWindowObject(); connect(frame, SIGNAL(javaScriptWindowObjectCleared()), this, SLOT(attachWindowObject())); connect(api, SIGNAL(win_bar()), this, SLOT(bluesBros())); setCentralWidget(view); }; void MainWindow::attachWindowObject() { frame->addToJavaScriptWindowObject(QString("api"), api); }; void MainWindow::bluesBros() { qDebug() << "foo and bar are getting the band back together!"; }; happyapi.h #ifndef HAPPYAPI_H #define HAPPYAPI_H #include <QObject> class HappyApi : public QObject { Q_OBJECT public: HappyApi(QObject *parent); public slots: void os_foo(); signals: void win_bar(); }; #endif // HAPPYAPI_H happyapi.cpp #include <QDebug> #include "happyapi.h" HappyApi::HappyApi(QObject *parent) : QObject(parent) { }; void HappyApi::os_foo() { qDebug() << "foo called, it want's it's bar back"; }; I'm reasonably new to C++ programming (coming from a web and python background). Hopefully this example will serve to not only help other new users, but be something interesting for a more experienced c++ programmer to elaborate on. Thanks for any assistance that can be provided. :)

  • jquery ajax post canceled

    - by hsemu
    I want to track the mouse click events on a set of UI components on a set of pages. To do this, I am using the following jquery/ajax call(trimmed out u): 1.Ajax call which will add the click logging. myClickLogger = { endpoint: '/path/to/my/logging/endpoint.html', logClickEvent: function(clickCode) { $.ajax({ 'type': 'POST', 'url': this.endpoint, 'async': true, 'cache': false, 'global': false, 'data': { 'clickCode':clickCode }, 'error': function(xhr,status,err){ alert("DEBUG: status"+status+" \nError:"+err); }, 'success': function(data){ if(data.status!=200){ alert("Error occured!"); } } }); } }; 2.JQuery click event which will call the ajax logger(the clickCode is an identifier for which button/image was clicked): $(document).ready(function() { $(".myClickEvent[clickName]").click(function() { var clickCode = $(this).attr("clickName"); myClickLogger.logClickEvent(clickCode); }); }); The above ajax call(1.) is "canceled" by browser whenever the button click being tracked takes to a new page. If I change 'aysnc' to 'false', then the ajax call succeeds. Also, click events which do not take to a new page succeed. Only the click events taking to new page are being canceled. I do not want to make the call synchronous. Any ideas, what could be the issue? How can I guarantee that the asynchronous call before is finished when the click event takes to a new page?

  • Javascript parse/evaluation order?

    - by Breck Fresen
    This is probably a nub question, but I don't understand why this works: <script type="text/javascript"> alert(foo); function foo() { } </script> This alerts "function foo() { }", but I expected the alert to be evaluated before the function foo was defined. Can someone explain what I don't understand about parse/evaluation order or point me to a resource that does? Thanks in advance, -- Breck

  • Flex / Flash builder : no returning data using database

    - by Tristan
    Hello, i'm following some flex tutorials everything's working as wanted expected for one thing : When i use my function getServerByBrand($brand) there is no returned data into my datagrid and i don't know why because it uses the same schema as getAllserver() which is working . I don't know whether it's cause by the function itselft or the configuration in flash builder : protected function RechercheGSP_clickHandler(event:MouseEvent):void { getServerByBrandResult.token = dbClass.getServerByBrand(SearchInput.text); } Here's what i've got in Data/Services : getServerByBrand(brand : string) : Object And finally the function : public function getServerByBrand($brand) { $stmt = mysqli_prepare($this->connection, "SELECT DISTINCT * FROM $this->tablename where GSP_nom=? "); $this->throwExceptionOnError(); mysqli_stmt_execute($stmt); $this->throwExceptionOnError(); $rows = array(); mysqli_stmt_bind_result($stmt, $row->idServ, $row->GSP_nom, $row->IPserv, $row->port, $row->tickrate, $row->membre, $row->nomPays, $row->finContrat, $row->actif, $row->timestamp, $row->type, $row->jeux, $row->slot, $row->ipClient, $row->essai, $row->reussite, $row->echec, $row->valide, $row->email); while (mysqli_stmt_fetch($stmt)) { $row->timestamp = new DateTime($row->timestamp); $rows[] = $row; $row = new stdClass(); mysqli_stmt_bind_result($stmt, $row->idServ, $row->GSP_nom, $row->IPserv, $row->port, $row->tickrate, $row->membre, $row->nomPays, $row->finContrat, $row->actif, $row->timestamp, $row->type, $row->jeux, $row->slot, $row->ipClient, $row->essai, $row->reussite, $row->echec, $row->valide, $row->email); } mysqli_stmt_free_result($stmt); mysqli_close($this->connection); return $rows; } I tested the settings with configure return type and it tells me : "the operation returned a primitive "object". test settings : Parameters (brand) / Input type (String) / Value (woop) To conclude, there is no returned object at all. Do you see the problem ? Thanks

  • echoing javascript when an ajax funtion is called

  • DRY programming dilemma

    - by fayer
    the situation is like this: im creating a Logger class that can write to a file but the write_to_file() function is in a helper class as a static function. i could call that function but then the Log class would be dependent to the helper class. isn't dependency bad? but if i can let it use a helper function then what is the point of having helper functions? what should one prioritize here: using helper functions and have to include this helper class everywhere (but the other 99 methods wont be useful) or just copy and paste into the Log class (but then if i have done this 100 times and then make a change i have to change in 100 places). share your thoughts and experience!

  • (jQuery) javascript setTimeout clearTimeout

    - by Tillebeck
    Hi I try to make a page to go to the startpage after eg. 10sec of inactivity (user not clicking anywhere). I use jQuery for the rest but the set/clear in my test function are pure javascript. In my frustation I ended up with something like this function that I hoped I could call on any click on the page. The timer starts fine, but is not reset on a click. If the function is called 5 times within the first 10 seconds, then 5 alerts will apear... no clearTimeout... function endAndStartTimer() { window.clearTimeout(timer); var timer; //var millisecBeforeRedirect = 10000; timer = window.setTimeout(function(){alert('Hello!');},10000); } Any one got some lines of code that will do the trick? - on any click stop, reset and start the timer. - When timer hits eg. 10sec do something.

  • OnmouseMove not work with SetTimeOut and Alerts in Chome

    - by Diogo Fernandes
    What's wrong with this code? It works in IE and FireFox, but Chrome does not work. The idea is that the function fnTimeOut will be triggered in 5 seconds after onmousemove. It´s ok. But when, in Chrome, I click on the button "ok" to function fnAlert is triggered instantly. It should be shot just 5 seconds after I move the mouse ... help me please. <input type="button" onclick="alert(1);" value="ok"> <script> document.onmousemove = fnTimeOut; var t = null; function fnAlert() { alert(2); } function fnTimeOut() { clearTimeout( t ); t = setTimeout( fnAlert, 5000 ); } </script>

  • Problems with jQuery load and getJSON only when using Chrome

    - by leftend
    I'm having an issue with two jQuery calls. The first is a "load" that retrieves HTML and displays it on the page (it does include some Javascript and CSS in the code that is returned). The second is a "getJSON" that returns JSON - the JSON returned is valid. Everything works fine in every other browser I've tried - except Chrome for either Windows or Mac. The page in question is here: http://urbanistguide.com/category/Contemporary.aspx When you click on a Restaurant name in IE/FF, you should see that item expand with more info - and a map displayed to the right. However, if you do this in Chrome all you get is the JSON data printed to the screen. The first problem spot is when the "load" function is called here: var fulllisting = top.find(".listingfull"); fulllisting.load(href2, function() { fulllisting.append("<div style=\"width:99%;margin-top:10px;text-align:right;\"><a href=\"#\" class=\"" + obj.attr("id") + "\">X</a>"); itemId = fulllisting.find("a.listinglink").attr("id"); ... In the above code, the callback function doesn't seem to get invoked. The second problem spot is when the "getJSON" function is called: $.getJSON(href, function(data) { if (data.error.length > 0) { //display error message } else { ... } In this case - it just seems to follow the link instead of performing the callback... and yes, I am doing a "return false;" at the end of all of this to prevent the link from executing. All of the rest of the code is inline on that page if you want to view the source code. Any ideas?? Thanks

  • Calling Model Functions from a Library

    - by Abs
    Hello all, I have turned a normal PHP class into a library so I can use it in Codeigniter as a library. I can load it and call the functions I need in that class. Here is that class to help with the question. However, there are quite a few points where I have to call functions in my class. These functions reside in the model that instantiated my class. How can I do this as currently normal calls don't work. Here is my code: class Controlpanel_model extends Model { var $category = ''; var $dataa = 'a'; function Controlpanel_model(){ parent::Model(); } function import_browser_bookmarks(){ $this->load->library('BookmarkParser'); /* *In this function call to the class I pass * what model functions exist that it should call * You can view how this done by clicking the link above and looking at line 383 */ $this->bookmarkparser->parseNetscape("./bookmarks.html", 0, 'myURL', 'myFolder'); return $this->dataa; } function myURL($data, $depth, $no) { $category = $this->category; $this->dataa .= 'Tag = '.$category.'<br />'.'URL = '.$data["url"].'<br />'.'Title = '.$data["descr"].'<br />'.'<br /><br />'; } function myFolder($data, $depth, $no) { $this->category = $data["name"]; } } Thanks all for any help.

  • Code coverage (c++ code execution path)

    - by Poni
    Let's say I have this code: int function(bool b) { // execution path 1 int ret = 0; if(b) { // execution path 2 ret = 55; } else { // execution path 3 ret = 120; } return ret; } I need some sort of a mechanism to make sure that the code has gone in any possible path, i.e execution paths 1, 2 & 3 in the code above. I thought about having a global function, vector and a macro. This macro would simply call that function, passing as parameters the source file name and the line of code, and that function would mark that as "checked", by inserting to the vector the info that the macro passed. The problem is that I will not see anything about paths that did not "check". Any idea how do I do this? How to "register" a line of code at compile-time, so in run-time I can see that it didn't "check" yet? I hope I'm clear.

  • Proper way to use a config file?

    - by user156814
    I just started using a PHP framework, Kohana (V2.3.4) and I am trying to set up a config file for each of my controllers. I never used a framework before, so obviously Kohana is new to me. I was wondering how I should set up my controllers to read my config file. For example, I have an article controller and a config file for that controller. I have 3 ways of loading config settings // config/article.php $config = array( 'display_limit' => 25, // limit of articles to list 'comment_display_limit' => 20, // limit of comments to list for each article // other things ); Should I A) Load everything into an array of settings // set a config array class article_controller extends controller{ public $config = array(); function __construct(){ $this->config = Kohana::config('article'); } } B) Load and set each setting as its own property // set each config as a property class article_controller extends controller{ public $display_limit; public $comment_display_limit; function __construct(){ $config = Kohana::config('article'); foreach ($config as $key => $value){ $this->$key = $value; } } } C) Load each setting only when needed // load config settings only when needed class article_controller extends controller{ function __construct(){} // list all articles function show_all(){ $display_limit = Kohana:;config('article.display_limit'); } // list article, with all comments function show($id = 0){ $comment_display)limit = Kohana:;config('article.comment_display_limit'); } } Note: Kohana::config() returns an array of items. Thanks

  • How do I DRY up my CouchDB views?

    - by James A. Rosen
    What can I do to share code among views in CouchDB? Example 1 -- utility methods Jesse Hallett has some good utility methods, including function dot(attr) { return function(obj) { return obj[attr]; } } Array.prototype.map = function(func) { var i, r = [], for (i = 0; i < this.length; i += 1) { r[i] = func(this[i]); } return r; }; ... Where can I put this code so every view can access it? Example 2 -- constants Similarly for constants I use in my application. Where do I put MyApp = { A_CONSTANT = "..."; ANOTHER_CONSTANT = "..."; }; Example 3 -- filter of a filter: What if I want a one view that filters by "is this a rich person?": function(doc) { if (doc.type == 'person' && doc.net_worth > 1000000) { emit(doc.id, doc); } } and another that indexes by last name: function(doc) { if (doc.last_name) { emit(doc.last_name, doc); } } How can I combine them into a "rich people by last name" view? I sort of want the equivalent of the Ruby my_array.select { |x| x.person? }.select { |x| x.net_worth > 1,000,000 }.map { |x| [x.last_name, x] } How can I be DRYer?

  • Question about functional OOP style in JavaScript

    - by valums
    I prefer to use functional OOP style for my code (similar to the module pattern) because it helps me to avoid the "new" keyword and all problems with the scope of "this" keyword in callbacks. But I've run into a few minor issues with it. I would like to use the following code to create a class. namespace.myClass = function(){ var self = {}, somePrivateVar1; // initialization code that would call // private or public methods privateMethod(); self.publicMethod(); // sorry, error here function privateMethod(){} self.publicMethod = function(){}; return self; } The problem is that I can't call public methods from my initialization code, as these functions are not defined yet. The obvious solution would be to create an init method, and call it before "return self" line. But maybe you know a more elegant solution? Also, how do you usually handle inheritance with this pattern? I use the following code, butI would like to hear your ideas and suggestions. namespace.myClass2 = function(){ var self = namespace.parentClass(), somePrivateVar1; var superMethod = self.someMethod; self.someMethod = function(){ // example shows how to overwrite parent methods superMethod(); }; return self; } Edit. For those who asked what are the reasons for choosing this style of OOP, you can look into following questions: http://stackoverflow.com/questions/1557386/prototypal-vs-functional-oop-in-javascript http://stackoverflow.com/questions/383402/is-javascript-s-new-keyword-considered-harmful

  • How to use Java varargs with the GWT Javascript Native Interface? (aka, "GWT has no printf()")

    - by markerikson
    I'm trying to quickly learn GWT as part of a new project. I found out that GWT doesn't implement Java's String.format() function, so there's no printf()-like functionality. I knew that some printf() implementations exist for Javascript, so I figured I could paste one of those in as a GWT Javascript Native Interface function. I ran into problems, and decided I'd better make sure that the varargs values were being passed in correctly. That's where things got ugly. First, some example code: // From Java, call the JSNI function: test("sourceString", "params1", "params2", "params3"); .... public static native void test(Object... params) /*-{ // PROBLEM: this kills GWT! // alert(params.length); // returns "function" alert(typeof(params)); // returns "[Ljava.lang.Object;@b97ff1" alert(params); }-*/; The GWT docs state that "calling a varargs JavaScript method from Java will result in the callee receiving the arguments in an array". I figured that meant I could at least check params.length, but accessing that throws a JavascriptException wrapped in an UmbrellaException, with no real information. When I do "typeof(params)", it returns "function". As if that weren't odd enough, if I check the string value of params, it returns what appears to be a string version of a Java reference. So, I guess I'm asking a few different questions here: 1) How do GWT/JSNI varargs actually work, and do I need to do something special to pass in values? 2) What is actually going on here? 3) Is there any easier way to get printf()-style formatting in a GWT application?

I can't seem to get it to work! $(document).ready(function(){ $("#healthForm").validate({ highlight: function(element, errorClass) { $(element).addClass(errorClass) $(element.form).find("label[for='type']") .addClass("radioerror"); }, unhighlight: function(element, errorClass) { $(element).removeClass(errorClass) $(element.form).find("label[for='type']") .removeClass("radioerror"); }, errorPlacement: function(error, element) { } }); });

  • jquery image hover popup cant detect browser edge and change its direction

    - by Salman
    hi guys i am trying to implement jquery image hover popup but facing a problem when the popup is closer to browser edge it goes beyond its edge i want it to change its direction when it finds that space is not enough to show that popup, i have see this effect in many plugins where popups, tooltips and drop down menus change their direction if they are close to browser window edge can any one guide me in right direction here is the screen shot for reference http://img512.imageshack.us/img512/4990/browseredge.png here is the jquery hover code function imagePreview(){ /* CONFIG */ xOffset = 10; yOffset = 30; // these 2 variable determine popup's distance from the cursor // you might want to adjust to get the right result /* END CONFIG */ $("a.preview").hover(function(e){ this.t = this.title; this.title = ""; var c = (this.t != "") ? "<br>" + this.t : ""; var newName = this.name; //console.log(this.name); newName=newName.replace("/l/","/o/"); //console.log(newName); $("body").append("<p id='preview'><img src='"+ this.name +"' alt='Image preview' style='margin-bottom:5px;'>"+ c +"</p>"); $("#preview img").error(function () { $("#preview img").attr("src" ,newName).css({'width': '400px', 'height': 'auto'}); }); $("#preview") .css("top",(e.pageY - xOffset) + "px") .css("left",(e.pageX + yOffset) + "px") .fadeIn("fast"); }, function(){ this.title = this.t; $("#preview").remove(); }); $("a.preview").mousemove(function(e){ $("#preview") .css("top",(e.pageY - xOffset) + "px") .css("left",(e.pageX + yOffset) + "px"); }); }; any help will be appriciated Thanks Salman
