    <p>I've installed a nice little jQuery mailer script that contains a required field (Subject) I don't want, and would like to remove it. First I simply removed the html, forgetting the verification and got an error. Then I tried to remove the part of the script that verifies if a Subject (a <code>&lt;select&gt;</code>) was chosen, but got an error, and am asking for help, now. Here's the script:</p> <p>html:</p> <pre><code>&lt;form id="contact-form" name="contact-form" method="post" action="submit.php"&gt; &lt;table width="100%" border="0" cellspacing="0" cellpadding="5"&gt; &lt;tr&gt; &lt;td width="25%" style="text-align:right;"&gt;&lt;label for="name"&gt;Name&lt;/label&gt;&lt;/td&gt; &lt;td width="65%" style="text-align:left;"&gt;&lt;input type="text" class="validate[required,custom[onlyLetter]]" name="name" id="name" value="&lt;?=$_SESSION['post']['name']?&gt;" /&gt;&lt;/td&gt; &lt;td width="10%" id="errOffset" style="text-align:right;"&gt;&amp;nbsp;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td style="text-align:right;"&gt;&lt;label for="email"&gt;Email&lt;/label&gt;&lt;/td&gt; &lt;td&gt;&lt;input type="text" class="validate[required,custom[email]]" name="email" id="email" value="&lt;?=$_SESSION['post']['email']?&gt;" /&gt;&lt;/td&gt; &lt;td&gt;&amp;nbsp;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;&lt;label for="subject"&gt;Subject&lt;/label&gt;&lt;/td&gt; &lt;td&gt;&lt;select name="subject" id="subject"&gt; &lt;option value="" selected="selected"&gt; - Choose -&lt;/option&gt; &lt;option value="Question"&gt;Question&lt;/option&gt; &lt;option value="Business proposal"&gt;Business proposal&lt;/option&gt; &lt;option value="Advertisement"&gt;Advertising&lt;/option&gt; &lt;option value="Complaint"&gt;Complaint&lt;/option&gt; &lt;/select&gt; &lt;/td&gt; &lt;td&gt;&amp;nbsp;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td valign="top" style="text-align:right;"&gt;&lt;label for="message"&gt;Message&lt;/label&gt;&lt;/td&gt; &lt;td&gt;&lt;textarea name="message" id="message" class="validate[required]" cols="35" rows="5"&gt;&lt;?=$_SESSION['post']['message']?&gt;&lt;/textarea&gt;&lt;/td&gt; &lt;td valign="top"&gt;&amp;nbsp;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;&lt;label for="captcha"&gt;&lt;?=$_SESSION['n1']?&gt; + &lt;?=$_SESSION['n2']?&gt; =&lt;/label&gt;&lt;/td&gt; &lt;td&gt;&lt;input type="text" class="validate[required,custom[onlyNumber]]" name="captcha" id="captcha" /&gt;&lt;/td&gt; &lt;td valign="top"&gt;&amp;nbsp;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td valign="top"&gt;&amp;nbsp;&lt;/td&gt; &lt;td colspan="2"&gt;&lt;input type="submit" name="button" id="button" value="Submit" /&gt; &lt;input type="reset" name="button2" id="button2" value="Reset" /&gt; &lt;?=$str?&gt; &lt;img id="loading" src="img/ajax-load.gif" width="16" height="16" alt="loading" /&gt;&lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; &lt;/form&gt; </code></pre> <p>And the script from where I'd like to remove the 'Subject' verification function:</p> <pre><code> $(document).ready(function(){ $('#contact-form').jqTransform(); $("button").click(function(){ $(".formError").hide(); }); var use_ajax=true; $.validationEngine.settings={}; $("#contact-form").validationEngine({ inlineValidation: false, promptPosition: "centerRight", success : function(){use_ajax=true}, failure : function(){use_ajax=false;} }) $("#contact-form").submit(function(e){ if(!$('#subject').val().length) { $.validationEngine.buildPrompt(".jqTransformSelectWrapper","* This field is required","error") return false; } if(use_ajax) { $('#loading').css('visibility','visible'); $.post('submit.php',$(this).serialize()+'&amp;ajax=1', function(data){ if(parseInt(data)==-1) $.validationEngine.buildPrompt("#captcha","* Wrong verification number!","error"); else { $("#contact-form").hide('slow').after('&lt;h1&gt;Thank you!&lt;/h1&gt;'); } $('#loading').css('visibility','hidden'); } ); } e.preventDefault(); }) }); </code></pre> <p>I'd tried removing the area indicated in the above code. The script has an 'are you human' simple math function, and after removing the code, I got an alert stating the answer to the simple math was wrong despite the fact that it was correct.</p>

    3. CO@jli - Yeah, I get that a lot. Thing is, there are quite a few questions that I've asked that have received no answer, or, whose answer came in the form of a comment. If I can use what was posted, or even get pointed in the right direction in the form of an answer, I accept.

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).
