    <p>In the sequence of this <a href="https://stackoverflow.com/questions/11121733/ajax-form-not-updating-values/11125356#11125356">question</a>, the content I've got in a form is now updating the DB. However, when I click this link </p> <pre><code>&lt;a onclick="doUpdate()" href="#" id="commit-changes" class="uibutton submit_form"&gt;Gravar&lt;/a&gt; </code></pre> <p>The jQuery .ajax function fires the error callback AND updates the DB with the information as well.</p> <p>Here's the code</p> <pre><code>function doUpdate() { e.preventDefault(); $.ajax({ type: "POST", data: $("#validation").serialize(), cache: false, url:"modules/user/updateuser.php", success : function(data){ $("#response-update").html(data); }, error: function(data){ $("#response-update").html("Erro na submissão"); } }); } </code></pre> <p>I'd like to get the success callback, in order to display a nice message to the user when it saves the data.</p> <p>However if I simply do this</p> <pre><code> &lt;a href="#" id="commit-changes" class="uibutton submit_form"&gt;Gravar&lt;/a&gt; &lt;script&gt; $(function(){ $('#commit-changes').click(function(e){ e.preventDefault(); $.ajax({ type: "POST", data: $("#validation").serialize(), cache: false, url:"modules/user/updateuser.php", success : function(data){ $("#response-update").html(data); }, error: function(data){ $("#response-update").html("Erro na submissão"); } }); }); }); &lt;/script&gt; </code></pre> <p>The "submition" doesn't work at all. </p> <p>How can I solve this problem? Been stuck with this part for days! :(</p> <p>EDIT - HTML for the form (This is also a response loaded in the begging of the page)</p> <pre><code> $response.='&lt;form id="validation" method="post"&gt; &lt;fieldset &gt; &lt;input type="hidden" name="user_id" value="'.$_POST['user_id'].'"/&gt; &lt;legend&gt;Actualizar Dados Utilizador&lt;/legend&gt; &lt;div class="section "&gt; &lt;label&gt;Nome&lt;small&gt;Insira o seu nome&lt;/small&gt;&lt;/label&gt; &lt;div&gt; &lt;input type="text" class="validate[required,custom[onlyLetterSp]] large" name="nome" id="f_required" value="'.utf8_encode($rcs_user-&gt;nome).'"&gt; &lt;/div&gt; &lt;/div&gt;'; $response.='&lt;div class="section "&gt; &lt;label&gt; Email&lt;small&gt;Insira o seu email&lt;/small&gt;&lt;/label&gt; &lt;div&gt; &lt;input type="text" class="validate[required,custom[email]] large" name="email" id="e_required" value="'. utf8_encode($rcs_user-&gt;email).'"&gt; &lt;/div&gt; &lt;/div&gt;'; $response.= '&lt;div class="section"&gt; &lt;label&gt;Permissões&lt;small&gt;Seleccione o tipo de utilizador &lt;/small&gt;&lt;/label&gt; &lt;div&gt; &lt;select class="medium" name="role"&gt; '.$role.' &lt;/select&gt; &lt;/div&gt; &lt;/div&gt; &lt;div class="section"&gt; &lt;label&gt;Activo&lt;small&gt;Activar utilizador&lt;/small&gt;&lt;/label&gt; &lt;div&gt; '.$activo.' &lt;span class="f_help"&gt;ON / OFF &lt;/span&gt; &lt;/div&gt; &lt;/div&gt; &lt;div class="section last"&gt; &lt;div&gt; &lt;a onclick="return doUpdate()" href="#" id="commit-changes" class="uibutton submit_form"&gt;Gravar&lt;/a&gt;&lt;a class="uibutton special" onClick="ResetForm()" title="Limpar Formulário" &gt;Limpar Formulário&lt;/a&gt; &lt;/div&gt; &lt;/div&gt; &lt;/fieldset&gt;&lt;/form&gt; </code></pre>

    1. COare you expecting the object as json? if yes, then try adding `contentType: 'application/json'` to your ajax call

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

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