copied!<p>You want to change your configuration to setup the auto complete correctly:</p> <pre><code>$("#update-text").autocomplete("<?php echo site_url('userProfile/autocomplete');?>", {dataType:"json", type:'POST'}); </code></pre> <p>EDIT: also, there isn't a <strong>type</strong> option on the current autocomplete plugin, not that I'm aware of, which causes issues with CI's url get filtering (as seen in the code at <a href="https://github.com/agarzola/jQueryAutocompletePlugin/blob/master/jquery.autocomplete.js" rel="nofollow">https://github.com/agarzola/jQueryAutocompletePlugin/blob/master/jquery.autocomplete.js</a>). You might need to modify the autocomplete code to let you use POST.</p> <p>EDIT: you appear to be using the jQuery UI implementation, not the standalone. Looking at the options described at <a href="http://jqueryui.com/demos/autocomplete/" rel="nofollow">http://jqueryui.com/demos/autocomplete/</a> you can not pass in <em>dataType</em> and <em>type</em> options at the top level: those are unsupported. Also, you should change your codeigniter method to look like this (define <em>mycallback</em> before you use it):</p> <pre><code> function autocomplete(){ // this takes the text field and whatever the user writes it autocompletes it. //Every single place and event in the database should be displayed in this view in this format $req = $this->input->post('updateText'); $arrResults = array('orange', 'apple', 'bannana'); function mycallback ($var) { global $req; if (preg_match('/^'.$req.'/', $var)) { return $var; } } $array = array_filter($arrResults, 'mycallback'); // filter the array containing search word using call back function $array1 = array(); // filter null array foreach ($array as $arr => $val) { if(!empty($val)) { $array1[] = $val; } } //echo out the json encoded array echo json_encode($array1); } </code></pre> <p>EDIT 2: to use POST for your requests, try this:</p> <pre><code>$("#update-text").autocomplete({ source: function( request, response ) { $.post( "<?php echo site_url('userProfile/autocomplete');?", { updateText: split(request.term).pop(); }, response ); }}); </code></pre> <p>Also, if you're using Firefox you can use Firebug to make sure requests are being fired.</p>
