    <p>I'm trying to make my contact form submission process work equally well whether the client has javascipt enabled or not.</p> <p>If javascript is enabled, then validation will be handled client-side when an onsubmit event is triggered which calls my validateContactForm() function:</p> <pre><code>&lt;form method="POST" action="email_processing.php" onsubmit="return validateContactForm();"&gt; </code></pre> <p>If false is returned, then the form isn't submitted and the client is directed to correct what he has done wrong.</p> <p>The form is submitted to the email_processing.php script on if true is returned by validateContactForm() or if javascript is disabled. The php script then revalidates the data and if everything is OK, it sends an email.</p> <p>If I were relying on javascript, I could have made this process asynchronous and just have the php script return a message which would get handled by a callback function client-side. This would either be an error message or a success message.</p> <p>But because I want to make this work for people with javascript disabled, I can't do that. </p> <p>If there's an error, I need to return the contact form page with error messages displayed in the contact form and if it's been a success I should maybe get rid of the contact form and just display a "thanks" message where the form used to be.</p> <p>I'd be interested to know whether stackoverflow users would:</p> <ol> <li><p>Submit the form to a php script which would then redirect to a different php / html page.</p></li> <li><p>Have the validation / email sending functions at the top of the contact us php page itself and each time the contact us page is loaded we check to see if certains variables have been set and if so then we know that we need to validate and send the emails and display the correct format / message.</p></li> <li><p>If I should be thinking about this differently. This must be a very common situation to handle and I have done it many times in lttle applications for myself where I knew that I would have javascript enabled, but I need to do this for a client and I want to make sure that it's done right.</p></li> </ol> <p>Many thanks in advance</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.
