    copied!<p>I thought I solved the issue in a preceding question but it is sill not working. I want to change the php variables ($start and $end called by var b1 and var b2) if the admin clicks on button. After this the new code should be availble for every visitor, so it should make a server request. Here is my updated code: </p> <pre><code>&lt;?php if(date('w') == 4){ // day 2 = Tuesday $start = strtotime('9:30'); $end = strtotime('12:30'); $timenow = date('U'); if ($timenow &gt;= $start &amp;&amp; $timenow &lt;= $end) { echo'&lt;div id="iar_eu"&gt;'; echo quick_chat(200, 'default', 1, 'left', 0, 0, 1, 1, 1); echo'&lt;/div&gt;'; } } ?&gt; &lt;/div&gt; &lt;?php if ( is_user_logged_in() ) { ?&gt; &lt;input type="submit" value="Start Chat" id="start_chat" style="position: absolute; top: 30px; left: 10px;" /&gt; &lt;?php } ?&gt; &lt;script type="text/javascript"&gt; if(jQuery('#start_chat').data('clicked')) { // change var b1 and b2 $.ajax({ type: "POST", url: "/web/htdocs/www.fattorefamiglia.com/home/wp-content/themes/child_care_creative/chat.php", dataType: 'json', data: { b1: "1:00", b2: "23:00" } }).done(function(data) { b1 = data.b1; b2 = data.b2; });} else { $.ajax({ type: "POST", url: "/web/htdocs/www.fattorefamiglia.com/home/wp-content/themes/child_care_creative/chat.php", dataType: 'json', data: { b1: "9:00", b2: "18:00" } }).done(function(data) { b1 = data.b1; b2 = data.b2; });} jQuery('#start_chat').click(function(){ $(this).data('clicked', true); var b1 = '&lt;?php echo $start; ?&gt;'; var b2 = '&lt;?php echo $end; ?&gt;'; }); &lt;/script&gt; </code></pre> <p>chat.php:</p> <pre><code>&lt;?php // variables if (!empty($_POST)) { $data['b1'] = $_POST['b1']; $data['b2'] = $_POST['b2']; } // to not lose them $_SESSION['chat'] = $data; // to keep it compatible with your old code $start = $data['b1']; $end = $data['b2']; // send the JSON formatted output echo json_encode($data); ?&gt; </code></pre> <p>Nothing happens when I click the button. What am I doing wrong?</p>
