    <p>I used to validate checkbox form with a code like this:</p> <pre><code>&lt;div&gt; &lt;form action="survey.php" method="post" name="survey"&gt; &lt;span class="form"&gt;&lt;input type="checkbox" name="event1" onClick="return countMarketing()"&gt;Event1&lt;/span&gt; &lt;span class"form"&gt;&lt;input type="checkbox" name="event2" onClick="return countMarketing()"&gt;Event2&lt;/span&gt; &lt;span class"form"&gt;&lt;input type="checkbox" name="event3" onClick="return countMarketing()"&gt;Event2&lt;/span&gt; &lt;!-- other forms --&gt; &lt;/form&gt; &lt;/div&gt; </code></pre> <p>And a javascript validation that is something like this (to limit the count of checkboxes checked):</p> <pre><code>function countMarketing() { var NewCountMarketing = 0 if (document.survey.event1.checked) {NewCountMarketing = NewCountMarketing + 1} if (document.survey.event2.checked) {NewCountMarketing = NewCountMarketing + 1} if (document.survey.event3.checked) {NewCountMarketing = NewCountMarketing + 1} if (NewCountMarketing == 3) { alert('Please choose only two') document.survey; return false; } } </code></pre> <p>And validation like this works. But now, say im using php to for the submission, how do i check if in JS if the name of the form is something like this:</p> <pre><code> &lt;input type="checkbox" name="events[]" id="event1" onClick="return countMarketing()"&gt;Event1 </code></pre> <p>Ive tried to change the JS to:</p> <pre><code>if (document.survey.events[].checked) {code here} if (document.survey.getElementByName('events[]').checked) {code here} if (document.survey.getElementById('event1').checked) {code here} </code></pre> <p>But it doesnt work.. any can shed some light on me about this? thank you very much :)</p>

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.
