  1. POPOST variable not changing
    text
    copied!<p>I have a form with some jQuery UI sortables that have <code>data-</code>attributes that get serialized into a hidden textbox, so when I send the form, my PHP script can look at the value of <code>$_POST["contents"]</code>(which is a string like this <code>1-2-2-1</code>) and pass it to my MySQL UPDATE query. The problem is, the reported value of the textbox before sending the form (from the javascript), is different than the one in <code>$_POST</code>.</p> <p><strong>The form:</strong></p> <pre><code>&lt;form method="post" action="?update"&gt; &lt;input type="text" name="id" style="display:none" value="1" /&gt; &lt;input type="text" name="path" placeholder="Endereço Ex.: /pacotes/pureenergy" value="/some/path" /&gt; &lt;input type="text" name="title" placeholder="Título da página" value="&lt;?php echo $t;?&gt;" /&gt;&lt;br /&gt; &lt;!-- Some stuff hidden for briefness --&gt; &lt;input type="text" id="ci" name="contents" style="display:none" value="1-2-2-1" /&gt; &lt;input type="submit" value="Atualizar página" onclick="updateForm()"&gt; &lt;/form&gt; </code></pre> <p><strong>The Javascript:</strong></p> <pre><code>function updateForm() { var txt = $("#dropzone li:first-of-type").data("id"); $("#dropzone li:not(:first-of-type)").each(function() { txt = txt+"-"+$(this).data("id"); }); $("#ci").text(txt); alert(txt); } </code></pre> <p><strong>The PHP:</strong></p> <pre><code>$id = $_POST["id"]; $p = $_POST["path"]; $t = $_POST["title"]; $c = $_POST["contents"]; mysql_query("UPDATE aruna.pages SET path='$p', title='$t', contents='$c' WHERE id=$id") or die(mysql_error()); </code></pre> <p>The value reported by the javascript <code>alert()</code> is behaving as intended, but when I send the form, the value of the <code>$_POST["contents"]</code> is the same that was hardcoded in the HTML.</p> <p><strong>EDIT:</strong> PHP doesn't complain about <code>$_POST["contents"]</code> being unset, which it would if there was a typo.</p>
