    text
    copied!<p>I used the following codes to add comment to a post and display it without refreshing the page, but somehow, it displays the comment twice instead of once, but it only saves it once in the database. When I refresh the page, it displays each comment only once though, so i guess the problem is with the "ajax response". Here are the codes, thanks for any help.</p> <p>JavaScript:</p> <pre><code>function addComment(pid) { var url; var comment = document.getElementById("comment").value; xml_http = getXmlHttpObject(); if (xml_http == null) return alert("Your browser is too old to run this page!"); url = '../auth.php?comment=' + comment + '&amp;pid=' + pid; url += '&amp;p=' + Math.random(); xml_http.onreadystatechange = commentStatus; xml_http.open("GET", url, true); xml_http.send(null); } function commentStatus() { $("#comm").append(xml_http.responseText); } </code></pre> <p>PHP:</p> <pre><code>include_once('include/comment.php'); addComment($_GET['pid'], filter($_GET['comment'])); if(empty($_SESSION['pic'])) $pic = "images/silh.gif"; else $pic = "/profile/image.php/{$_SESSION['uname']}.{$_SESSION['pic']}?width=45&amp;amp;cropratio=1:1&amp;amp;image=/profile/pix/{$_SESSION['uname']}.{$_SESSION['pic']}"; echo "&lt;div id='comments'&gt;\n" ."&lt;img src='{$pic}' align='left' style='padding-right:5px' /&gt;" ."&lt;span id='bluetxt'&gt;By {$_SESSION['uname']}&lt;/span&gt;&lt;br /&gt;\n" ."&lt;span&gt;Posted Now&lt;/span&gt;\n" ."&lt;br /&gt;&lt;br /&gt;&lt;p style='clear:both'&gt;{$_GET['comment']}&lt;/p&gt;" . "&lt;/div&gt;&lt;br /&gt;\n"; </code></pre> <p>I purposely don't read the comment from the database, I simply post it back on the page.</p>

An individual column

Larger individual text columns get their own page to allow for proper reading.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
