    <p><strong>Edit</strong></p> <p>Your company is asking you to do the address validation on the server. Sometimes you want to do it in both places, ie:</p> <ul> <li>On the client: To provide instant feedback about whether input is valid <em>before</em> submitting</li> <li>On the server: To validate the input in case some bad input got through</li> </ul> <p>Your form data is submitted to the server via a <code>POST</code> request (usually), so the PHP endpoint that handles the request must get the form field from the request and validate it.</p> <p>For instance, you might "get" the email address by doing:</p> <p><code>$emailAddress = $_POST["email"];</code></p> <p>The <code>$_POST</code> array is specific to each request and has all of the form data in a dictionary (well really an array I think, but whatever). In general, you can get the form data by doing <code>$_POST["the_input_id"]</code> where <code>the_input_id</code> is the form element's input ID.</p> <p>Once you get the stuff you need, then you can do the validation.</p> <p><strong>PHP Side</strong></p> <p>See <a href="https://stackoverflow.com/questions/201323/using-a-regular-expression-to-validate-an-email-address">Using a regular expression to validate an email address</a> to find a good RegEx to validate your email addresses.</p> <p>There is no "canonical" RegEx that I know of for email addresses as different servers allow different sorts of addresses. The RFC for what actually is a valid email address is not uniformly followed.</p> <p>For instance, a very intense RegEx is available at <a href="http://www.ex-parrot.com/~pdw/Mail-RFC822-Address.html" rel="nofollow noreferrer">http://www.ex-parrot.com/~pdw/Mail-RFC822-Address.html</a>.</p> <p>Then use php's built-in RegEx functions, ie:</p> <pre><code>$EmailRegEx = "^[a-zA-Z0-9.!#$%&amp;'*+/=?^_`{|}~-]+@[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?(?:\.[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?)*$"; $InputAddress = "tacos_tacos_tacos@nowhere.com"; $EmailAddressValid = preg_match($EmailRegEx, $InputAddress); if ($EmailAddressValid) { $this-&gt;_SendMe(); } </code></pre> <p>See <a href="http://www.developphp.com/view_lesson.php?v=224" rel="nofollow noreferrer">http://www.developphp.com/view_lesson.php?v=224</a> for a simple example.</p>

    2. COPeople on StackOverflow are super generous and very eager to help you but you must (among other things) 1) clearly explain your problem, 2) show what you have tried to do already and the (not working) result, 3) ask a constructive question about what should be done / the underlying reason why it is not working. I am pretty lenient about these but the more serious SO users do not take kindly to asking for providing code in this way.

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).
