  • Can't access dynamically generated div with Jquery

    - by Bug Magnet
    Still trying to get my head around JQuery and dynamically generated content. I have the following code that is dynamically generated with JQuery whenever a user clicks on an 'Add' button: <div id="practices_div" style="border-top: 1px dotted gray"> <br/> <a href="#" class="remove_link" rel="practices_div">Remove</a> ....content goes here </div> The JQuery code that dynamically loads the above content is as follows: $.ajax({ url: '/addAjax.html', success: function(response) { $('#container').append(response); } }); What I'm trying to do is when a user clicks on the Remove link, JQuery should hide and delete the dynamically generated content from the page. The code that does this is as follows: $('.remove_link').live('click', function() { if (confirm("Remove this item?")) { $('#practices_div').fadeOut('medium', function() { $(this).remove(); }); } return false; }); So, when the content is dynamically loaded via Ajax, and I click on the Remove link, the Confirmation dialogue box is displayed and if I confirm, nothing happens. For some reason, JQuery is not able find the dynamically generated #practices_div. Any idea what I may be doing wrong?

  • How to Refresh / Reload a KML layer in OpenLayers. Dynamic KML Layer.

    - by Ozaki
    TLDR See my answer below on how to refresh the layer. So far I have tried action function as follows: function RefreshKMLData(layer) { layer.loaded = false; layer.setVisibility(true); layer.redraw({ force: true }); } set interval of the function: window.setInterval(RefreshKMLData, 5000, KMLLAYER); the layer itself: var KMLLAYER = new OpenLayers.Layer.Vector("MYKMLLAYER", { projection: new OpenLayers.Projection("EPSG:4326"), strategies: [new OpenLayers.Strategy.Fixed()], protocol: new OpenLayers.Protocol.HTTP({ url: MYKMLURL, format: new OpenLayers.Format.KML({ extractStyles: true, extractAttributes: true }) }) }); the url for KMLLAYER with Math random so it doesnt cache: var MYKMLURL = var currentanchorpositionurl = 'http://' + host + '/data?_salt=' + Math.random(); I would have thought that this would Refresh the layer. As by setting its loaded to false unloads it. Visibility to true reloads it and with the Math random shouldn't allow it to cache? So has anyone done this before or know how I can get this to work? TLDR See my answer below on how to refresh the layer.

  • JS: Object itteration fails

    - by Newbie
    Hello! In my JS, I have an object called box_object. It looks like this: ({ id:"3", text:"this is a box object", connection_parent:["1", "2"], connection_child:["5", "6"], connectiondata_child:{ 0:{id:"5", linepoint:"bottom"}, 1:{id:"6", linepoint:"bottom"}}, connectiondata_parent:{ 0:{id:"1", linepoint:"top"}, 1:{id:"2", linepoint:"top"}} }) Now, I want to add some position values to box_object.connectiondata_parent. Using jQuery I can use the .each() method. So I tried it, but it failed. In my function I do the following: $(box_object.connectiondata_parent).each(function(it, obj){ if(typeof(obj[it]) != "undefined" && obj[it].linepoint == "top"){ var point_position_top = new Object(); point_position_top.left = startingpoint_left; point_position_top.top = startingpoint_top; obj[it].position = point_position_top; }else if(typeof(obj[it]) != "undefined" && obj[it].linepoint == "bottom"){ var point_position_bottom = new Object(); point_position_bottom.left = startingpoint_left; point_position_bottom.top = startingpoint_bottom; obj[it].position = point_position_bottom; }else{} }); After the function my box_object looks like this: ({ id:"3", text:"this is third box", connection_parent:["1", "2"], connection_child:["5", "6"], connectiondata_child:{ 0:{id:"5", linepoint:"bottom"}, 1:{id:"6", linepoint:"bottom"}}, connectiondata_parent:{ 0:{id:"1", linepoint:"top", position:{left:500, top:104}}, 1:{id:"2", linepoint:"top"}} }) It seems it only writes the values to the first "value". Any Ideas why?

  • JQuery Checkbox generation

    - by Hash
    I have used the following code to generate some dynamic checkboxes. This works for the first time and adds the check box chk2 to the page and then after the trigger for the $('#newLink').click is not working. Please help me with this. <div id="chkBoxesDiv"> <input type="checkbox" id="chk1" ></input> <input id="answerText" type="text" size="30" ></input>&nbsp; <input type="button" value="add new" id="newLink"/> </div> $(document).ready(function(){ $('#newLink').click(function (event){ var i = 0; //To count the children $("#chkBoxesDiv").children().each(function(){ var child = $(this); if(child.is(":checkbox")){ i++; } }); //prevent action event.preventDefault(); //get textbox value to fill checkbox var text = $("#answerText").val(); alert(i); //if text not empty do stuff if(text != ""){ //add label $("#chk"+i).after("<label for=\"chk"+i+"\" id=\"lblchk"+i+"\">"+text+"</label>"); $("#newLink").remove(); $("#answerText").remove(); $("#lblchk1").after("<br /><input type=\"checkbox\" id=\"chk"+(1+i)+"\" ></input><input type=\"text\" id=\"answerText\" size=\"30\" ></input>&nbsp;<input type=\"button\" value=\"add new\" id=\"newLink\"/>"); } }); });

  • Jquery tabs with cookie support restore wrong tab position after page refresh.

    - by zenonych
    Hello, all. I have tricky problem which I can't completely understand... It's jquery tabs with cookie support. I've following code: $(document).ready(function() { var $tabs = $("#tabs").tabs(); $tabs.tabs('select', $.cookie("tabNumber")); $('#tabs ul li a').click(function() { $.cookie("tabNumber", $tabs.tabs('option', 'selected')); }); $('#btnSelect').click(function() { //alert($.cookie("tabNumber")); //$tabs.tabs('select', 2); $tabs.tabs('select', $.cookie("tabNumber")); }); }); So, I've 3 tabs (with positions 0,1,2) inside div named "tabs". When user selects one tab, then tab position stores in cookie. After that if user refresh page, active tab position must be restored. But each time I refresh page I get active tab in previous position (if I select 2nd tab, then after refresh I got active tab in position 1, etc.). I add some test in code (button btnSelect with onclick handler which duplicates load position functionality). So, if I uncomment and use $tabs.tabs('select', 2); Then after I click btnSelect I've got right position. Ok, that's right. Then I comment that line and uncomment next one: alert($.cookie("tabNumber")); So, I select tab, click button, get dialog message "2", and after that tab in position 1 became active. Why?? In both cases I call 'select' method with parameter 2... I know I can use aliases for tabs, but I want to understate why my code doesn't work properly.

  • autocomplete: how do I avoid a duplicate search?

    - by dnagirl
    I use JQuery plugin autocomplete as a kind of dataset chooser. If the user chooses a value from the autocomplete lookup, the database is queried for the matching dataset. If the user types in a new value, the user can enter a new dataset. An issue arises when the user types in an existing value rather than choosing it from the autocomplete lookup. When this is done, the autocomplete .result() method is not called and no dataset is retrieved. To fix this I added a .blur(function(){$(this).search();}); to the input element. This fixed the original problem. Now I have the problem that .result() fires on selection from lookup AND on blur. I would like .result() to fire on selection from lookup OR on blur. How do I make that happen? Here is my code: $('#groupset').autocomplete('ajax/php/leeruns.php'); $('#groupset').result( function(event, data, formatted) { if(data){ $('#groupsetdesc').val(formatted); groups.load(data[1]); //retrieve matching dataset } else { $('#groupsetdesc').val(''); } } ).blur(function(){$(this).search();});

  • Simple problem with mod_rewrite in the Fat Free Framework

    - by ian
    I am trying to setup and learn the Fat Free Framework for PHP. http://fatfree.sourceforge.net/ It's is fairly simple to setup and I am running it on my machine using MAMP. I was able to get the 'hello world' example running just fin: require_once 'path/to/F3.php'; F3::route('GET /','home'); function home() { echo 'Hello, world!'; } F3::run(); But when I try to add in the second part, which has two routes: require_once 'F3/F3.php'; F3::route('GET /','home'); function home() { echo 'Hello, world!'; } F3::route('GET /about','about'); function about() { echo 'About Us.'; } F3::run(); I get a 404 error if I try the second URL: /about Not sure why one of the mod_rewrite commands would be working and not the other. Below is my .htaccess file: # Enable rewrite engine and route requests to framework RewriteEngine On RewriteBase / RewriteCond %{REQUEST_FILENAME} !-l RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule .* index.php [L,QSA] # Disable ETags Header Unset ETag FileETag none # Default expires header if none specified (stay in browser cache for 7 days) <IfModule mod_expires.c> ExpiresActive On ExpiresDefault A604800 </IfModule>

  • Jquery Ajax + PHP

    - by Kris.Mitchell
    I am having problems with jQuery Ajax and PHP I have my php file set up to echo the data I am gathering from a mysql database. I have verified that the database is returning something and that the string at the end of the function actually contains data. What is happening though, is that it looks like the php echo is happening before the ajax call, causing the php data to be displayed at the top of the page, and not below in proper div. I think it might have something to do with timing of the ajax and the php call, but I am not sure. So, why is the data not getting caught by the .ajax and thrown into the div? Thanks for the help! jQuery $(document).ready(function() { $.ajax({ url: "../database_functions.php", type: "GET", data: "cat=jw&sub=pi&sort=no", cache: false, success: function (html) { alert("Success!"); $('#product-list').html(html); } }); }); PHP echo "Hello World";

  • qTip pop ups come in from top left of screen (on first load)

    - by franko75
    Hi, not sure if i'm set things up incorrectly - I don't seem to see anyone else with this problem, but my qTip popups (all ajax loaded content) are loading quite erratically, in that they are often animating in from off screen before appearing in the correct position. Is there a simple solution to this which I may have missed? Thanks again for your help. HTML markup: <span class="formInfo"> <a href="http://localhost/httpdocs/index.php/help/kc_dob" class="jTip" name="" id="dob_help">?</a> </span> qTip initialisation.. //set up for qtip function initQtip() { $('a.jTip').each(function() { $(this).qtip( { content: { // Set the text to an image HTML string with the correct src URL to the loading image you want to use text: '<img src="/media/images/wait.gif" alt="Loading..." />', url: $(this).attr('href') // Use the rel attribute of each element for the url to load }, position: { adjust: { screen: true // Keep the tooltip on-screen at all times } }, show: { when: 'click', solo: true // Only show one tooltip at a time }, hide: 'unfocus', style: { tip: true, // Apply a speech bubble tip to the tooltip at the designated tooltip corner border: { width: 10, radius: 10 }, width: { min: 200, max: 500 }, name: 'light' // Use the default light style } }); //prevent default event on click }).bind('click', function(event){ event.preventDefault(); return false; }); }

  • Java reflection appropriateness

    - by jsn
    This may be a fairly subjective question, but maybe not. My application contains a bunch of forms that are displayed to the user at different times. Each form is a class of its own. Typically the user clicks a button, which launches a new form. I have a convenience function that builds these buttons, you call it like this: buildButton( "button text", new SelectionAdapter() { @Override public void widgetSelected( SelectionEvent e ) { showForm( new TasksForm( args... ) ); } } ); I do this dozens of times, and it's really cumbersome having to make a SelectionAdapter every time. Really all I need for the button to know is what class to instantiate when it's clicked and what arguments to give the constructor, so I built a function that I call like this instead: buildButton( "button text", TasksForm.class, args... ); Where args is an arbitrary list of objects that you could use to instantiate TasksForm normally. It uses reflection to get a constructor from the class, match the argument list, and build an instance when it needs to. Most of the time I don't have to pass any arguments to the constructor at all. The downside is obviously that if I'm passing a bad set of arguments, it can't detect that at compilation time, so if it fails, a dialog is displayed at runtime. But it won't normally fail, and it'll be easy to debug if it does. I think this is much cleaner because I come from languages where the use of function and class literals is pretty common. But if you're a normal Java programmer, would seeing this freak you out, or would you appreciate not having to scan a zillion SelectionAdapters?

  • Update on: How to model random non-overlapping spheres of non-uniform size in a cube using Matlab?

  • drupal hook_menu_alter9) for adding tabs

    - by EricP
    I want to add some tabs in the "node/%/edit" page from my module called "cssswitch". When I click "Rebuild Menus", the two new tabs are displayed, but they are displayed for ALL nodes when editing them, not just for the node "cssswitch". I want these new tabs to be displayed only when editing node of type "cssswitch". The other problem is when I clear all cache, the tabs completely dissapear from all edit pages. Below is the code I wrote. function cssswitch_menu_alter(&$items) { $node = menu_get_object(); //print_r($node); //echo $node->type; //exit(); if ($node->type == 'cssswitch') { $items['node/%/edit/schedulenew'] = array( 'title' => 'Schedule1', 'access callback'=>'user_access', 'access arguments'=>array('view cssswitch'), 'page callback' => 'cssswitch_schedule', 'page arguments' => array(1), 'type' => MENU_LOCAL_TASK, 'weight'=>4, ); $items['node/%/edit/schedulenew2'] = array( 'title' => 'Schedule2', 'access callback'=>'user_access', 'access arguments'=>array('view cssswitch'), 'page callback' => 'cssswitch_test2', 'page arguments' => array(1), 'type' => MENU_LOCAL_TASK, 'weight'=>3, ); } } function cssswitch_test(){ return 'test'; } function cssswitch_test2(){ return 'test2'; } Thanks for any help.

  • PHP modifying and combining array

    - by Industrial
    Hi everyone, I have a bit of an array headache going on. The function does what I want, but since I am not yet to well acquainted with PHP:s array/looping functions, so thereby my question is if there's any part of this function that could be improved from a performance-wise perspective? I tried to be as complete as possible in my descriptions in each stage of the functions which shortly described prefixes all keys in an array, fill up eventual empty/non-valid keys with '' and removes the prefixes before returning the array: $var = myFunction ( array('key1', 'key2', 'key3', '111') ); function myFunction ($keys) { $prefix = 'prefix_'; $keyCount = count($keys); // Prefix each key and remove old keys for($i=0;$i<$keyCount; $i++){ $keys[] = $prefix.$keys[$i]; unset($keys[$i]); } // output: array('prefix_key1', 'prefix_key2', 'prefix_key3', '111) // Get all keys from memcached. Only returns valid keys $items = $this->memcache->get($keys); // output: array('prefix_key1' => 'value1', 'prefix_key2' => 'value2', 'prefix_key3'=>'value3) // note: key 111 was not found in memcache. // Fill upp eventual keys that are not valid/empty from memcache $return = $items + array_fill_keys($keys, ''); // output: array('prefix_key1' => 'value1', 'prefix_key2' => 'value2', 'prefix_key3'=>'value3, 'prefix_111' => '') // Remove the prefixes for each result before returning array to application foreach ($return as $k => $v) { $expl = explode($prefix, $k); $return[$expl[1]] = $v; unset($return[$k]); } // output: array('key1' => 'value1', 'key2' => 'value2', 'key3'=>'value3, '111' => '') return $return; } Thanks a lot!

  • Handling Apache Thrift list/map Return Types in C++

    - by initzero
    First off, I'll say I'm not the most competent C++ programmer, but I'm learning, and enjoying the power of Thrift. I've implemented a Thrift Service with some basic functions that return void, i32, and list. I'm using a Python client controlled by a Django web app to make RPC calls and it works pretty well. The generated code is pretty straight forward, except for list returns: namespace cpp Remote enum N_PROTO { N_TCP, N_UDP, N_ANY } service Rcon { i32 ping() i32 KillFlows() i32 RestartDispatch() i32 PrintActiveFlows() i32 PrintActiveListeners(1:i32 proto) list<string> ListAllFlows() } The generated signatures from Rcon.h: int32_t ping(); int32_t KillFlows(); int32_t RestartDispatch(); int32_t PrintActiveFlows(); int32_t PrintActiveListeners(const int32_t proto); int64_t ListenerBytesReceived(const int32_t id); void ListAllFlows(std::vector<std::string> & _return); As you see, the ListAllFlows() function generated takes a reference to a vector of strings. I guess I expect it to return a vector of strings as laid out in the .thrift description. I'm wondering if I am meant to provide the function a vector of strings to modify and then Thrift will handle returning it to my client despite the function returning void. I can find absolutely no resources or example usages of Thrift list< types in C++. Any guidance would be appreciated.

  • Chrome extension javascript array bug?

    - by Wayne Werner
    Hi, I'm working on a Google Chrome extension. In the popup I have the following code: var bookmarks = []; function appendBMTnode(node){ bookmarks.push([node[0].title, node[0].id]); } function addchildren(results){ for(x = 0; x < results.length; x++){ bookmarks.push([results[x].title, results[x].id]); chrome.bookmarks.getChildren(results[x].id, addchildren); } } function getallbookmarks(){ chrome.bookmarks.get('0', appendBMTnode); chrome.bookmarks.getChildren('0', addchildren); } console.debug(bookmarks.length); console.debug(bookmarks); Now, I would assume that the first command would issue the # of bookmarks I have. Indeed, when I use Chrome's debugger and add bookmarks.length to the watch list, 418 is the value. In the console of the debugger I can write bookmarks.length and it will give me the correct length. I can type for(x = 0; x < bookmarks.length; x++){ console.debug(bookmarks[x]); } and I get string representations of each inner array. However, that original console.debug(bookmarks.length) gives an output of zero. And if I add console.debug(bookmarks[0]); to the popup.html it tells me that the value is undefined. This seems like a bug to me, but my real question is how can I iterate over this list? Thanks

  • How to detect what allowed character in current Regular Expression by using JavaScript?

    - by Soul_Master
    In my web application, I create some framework that use to bind model data to control on page. Each model property has some rule like string length, not null and regular expression. Before submit page, framework validate any binded control with defined rules. So, I want to detect what character that is allowed in each regular expression rule like the following example. "^[0-9]$" allow only digit characters like 1, 2, 3. "^[a-zA-Z_][a-zA-Z_-0-9]+$" allow only a-z, - and _ characters However, this function should not care about grouping, positioning of allowed character. It just tells about possible characters only. By the way, complex regular expression like find two words near(\bword1\W+(?:\w+\W+){1,6}?word2\b) must be ignore to verify and it should return any characters is possible. Do you have any idea for creating this function? PS. I know it easy to create specified function like numeric only for allowing only digit characters. But I need share/reuse same piece of code both data tier(contains all model validator) and UI tier without modify anything. Thanks

  • Broken JS Loop with Google Maps...

    My code is below, and I had an issue with nearly the same code, and it was fixed here on StackOverflow, but, again, its not working. I haven't changed the working code, but i did wrap it in the for...in loop youll see below. The issue is that no matter what marker I click it always triggers the last marker/infoWindow that was placed. $(function(){ var latlng = new google.maps.LatLng(45.522015,-122.683811); var settings = { zoom: 10, center: latlng, disableDefaultUI:true, mapTypeId: google.maps.MapTypeId.SATELLITE }; var map = new google.maps.Map(document.getElementById("map_canvas"), settings); $.getJSON('api',function(json){ for (var property in json) { if (json.hasOwnProperty(property)) { var json_data = json[property]; var the_marker = new google.maps.Marker({ title:json_data.item.headline, map:map, clickable:true, position:new google.maps.LatLng( parseFloat(json_data.item.geoarray[0].latitude), parseFloat(json_data.item.geoarray[0].longitude) ) }); var infowindow = new google.maps.InfoWindow({ content: '<div><h1>'+json_data.item.headline+'</h1><p>'+json_data.item.full_content+'</p></div>' }); new google.maps.event.addListener(the_marker, 'click', function() { infowindow.open(map,the_marker); }); } } }); }); Thank you for whoever figures this out!

  • Uploading multiple files asynchronously by blueimp jquery-fileupload

    - by Ryo
    I'm using jQuery File Upload library (http://github.com/blueimp/jQuery-File-Upload), and I've been stuck figuring out how to use the library satisfying the following conditions. The page has multiple file input fields surrounded by a form tag. Users can attach multiple files to each input field All files are sent to a server when the button is clicked, not when files are attached to the input fields. Upload is done asynchronously Say the page has 3 input fields with their name attributes being "file1[]", "file2[]" and "file3[]", the request payload should be like {file1: [ array of files on file1[] ], file2: [ array of files on file2[] ], ...} Here's jsFiddle, it's behaving weird so far in that it sends post request twice and the first one is cancelled. http://jsfiddle.net/BAQtG/24/ The core part of js code looks like this. $(document).ready(function(){ var filesList = [] var elem = $("form") file_upload = elem.fileupload({ formData:{extra:1}, autoUpload: false, fileInput: $("input:file"), }).on("fileuploadadd", function(e, data){ filesList.push(data.files[0]) }); $("button").click(function(){ file_upload.fileupload('send', {files:filesList} ) }) }) Anybody have idea how to get this to work? Updates Now thanks to @CBroe 's comment, the issue that request is sent twice is fixed. However the keys of request parameter is not correctly set. Here's updated jsFiddle. http://jsfiddle.net/BAQtG/27/

  • Symfony2 entity field type alternatives to "property" or "__toString()"?

    - by Polmonino
    Using Symfony2 entity field type one should specify property option: $builder->add('customers', 'entity', array( 'multiple' => true, 'class' => 'AcmeHelloBundle:Customer', 'property' => 'first', )); But sometimes this is not sufficient: think about two customers with the same name, so display the email (unique) would be mandatory. Another possibility is to implement __toString() into the model: class Customer { public $first, $last, $email; public function __toString() { return sprintf('%s %s (%s)', $this->first, $this->last, $this->email); } } The disadvances of the latter is that you are forced to display the entity the same way in all your forms. Is there any other way to make this more flexible? I mean something like a callback function: $builder->add('customers', 'entity', array( 'multiple' => true, 'class' => 'AcmeHelloBundle:Customer', 'property' => function($data) { return sprintf('%s %s (%s)', $data->first, $data->last, $data->email); }, ));

Up until this point I have made this really simple FAQ page. <script type="text/javascript" src="jquery.js"></script> <script type="text/javascript"> $(document).ready(function() { $("#void").click(function(event) { event.preventDefault(); }); $('#faq').find('dd').hide().end().find('dt').click(function() { $(this).next().slideToggle(); }); }); </script> <dl id="faq"> <dt><a href="" id="void">Coffee</a></dt> <dd>- black hot drink</dd> <dt><a href="" id="void">Milk</a></dt> <dd>- white cold drink</dd> </dl> The problem is only the first item is working. My questions are, why is only the first entree working and how do I fix it? I've tried using an each() but I am unsure where to put it.

  • Segmentation fault on certain inputs and not others

    - by Brandon Schwandt
    Heres a function I wrote that has some debugging elements in it already. When i enter either a "y" or a "Y" as the input I get a segmentation fault during runtime. When I enter any other value the code runs. The seg fault kicks out after it scans and gives me the response but before the "scan worked" line is output. DOn't know why it would act like this only on these values. If anyone needs the function call I have that as well. query_user(char *response [10]) { printf("response after query call before clear=%s\n",response); strcpy(response,""); printf("response after clearing before scan=%s\n",response); printf("Enter another person into the line? y or n\n"); scanf("%s", response); printf("response after scan=%s\n",response); printf("scan worked"); } main() { char response [10]; strcpy(response,"y"); printf("response=%s\n",response); printf("When finished with program type \"done\" to exit\n"); while (strcmp(response,"done") != 0) { printf("response after while loop and before query call=%s\n",response); query_user(&response); } } output on error: response after query call before clear=y response after clearing before scan= Enter another person into the line? y or n y response after scan=y Segmentation Fault (core dumped) output on non-error: response after query call before clear=y response after clearing before scan= Enter another person into the line? y or n n response after scan=n scan worked Cycle number 0 (program continues to run outside this function)

  • C++ read registry string value in char*

    - by Sunny
    I'm reading a registry value like this: char mydata[2048]; DWORD dataLength = sizeof(mydata); DWORD dwType = REG_SZ; ..... open key, etc ReqQueryValueEx(hKey, keyName, 0, &dwType, (BYTE*)mydata, &dataLength); My problem is, that after this, mydata content looks like: [63, 00, 3A, 00, 5C, 00...], i.e. this looks like a unicode?!?!. I need to convert this somehow to be a normal char array, without these [00], as they fail a simple logging function I have. I.e. if I call like this: WriteMessage(mydata), it outputs only "c", which is the first char in the registry. I have calls to this logging function all over the place, so I'd better of not modify it, but somehow "fix" the registry value. Here is the log function: void Logger::WriteMessage(const char *msg) { time_t now = time(0); struct tm* tm = localtime(&now); std::ofstream logFile; logFile.open(filename, std::ios::out | std::ios::app); if ( logFile.is_open() ) { logFile << tm->tm_mon << '/' << tm->tm_mday << '/' << tm->tm_year << ' '; logFile << tm->tm_hour << ':' << tm->tm_min << ':' << tm->tm_sec << "> "; logFile << msg << "\n"; logFile.close(); } }

  • Use string to store statement (or part of a statement), and then add it to the code

    - by Dean
    I use multidimensional arrays to store product attributes (well Virtuemart does, to be precise). When I tried to echo the sub-arrays value, if the sub-array did not exist PHP threw: Fatal error: Cannot use string offset as an array To get around this, I attempted to create a function to check on every array level if it is an actual array, and if it is empty (when trying on the whole thing at once such as: is_array($array['level1']['level2']['level3']), I got the same error if level1 or level2 are not actual arrays). This is the function ($array contains the array to check, $array_levels is an array containing the names of the sub-arrays, in the order they should apper): function check_md_array($array,$array_levels){ if(is_array($array)){ $dimension = null; //This will store the dimensions string foreach($array_levels as $level){ $dimension .= "['" . $level . "']"; //Add the current dimension to the dimensions string if(!is_array($array/* THE CONTENT OF $dimension SHOULD BE INSERTED HERE*/)){ return false; } } return true; } } How can I take the string contained in $dimensions, and insert it into the code, to be part of the statement?
