    <p>I have a PHP mail script that validates name, email address, and phone number before sending the mail. This then means that the Name, Email address, and Phone fields are <strong>Required</strong> Fields. </p> <p>I want to have it so that the <em>Name</em> and <strong><em>EITHER</em></strong> <em>Email</em> or <em>Phone</em> are required. Such that if a name and phone are inputted, it sends the mail, or if a name and an email are inputted, it also sends the email. </p> <p>The way the script works right now is it has several IF statements that check for (1) name, (2) email and (3) phone. Here's an example of an if statement of the code:</p> <pre><code>if ( ($email == "") ) { $errors .= $emailError; // no email address entered $email_error = true; } if ( !(preg_match($match,$email)) ) { $errors .= $invalidEmailError; // checks validity of email $email_error = true; } </code></pre> <p>And here's how it sends the mail:</p> <pre><code> if ( !($errors) ) { mail ($to, $subject, $message, $headers); echo "&lt;p id='correct'&gt;"; echo "ההודעה נשלחה בהצלחה!"; echo "&lt;/p&gt;"; } else { if (($email_error == true)) { $errors != $phoneError; /*echo "&lt;p id='errors'&gt;"; echo $errors; echo "&lt;/p&gt;";*/ } if (($phone_error == true)) { $errors != $emailError; $errors != $invalidEmailError; /*echo "&lt;p id='errors'&gt;"; echo $errors; echo "&lt;/p&gt;";*/ } echo "&lt;p id='errors'&gt;"; echo $errors; echo "&lt;/p&gt;"; } </code></pre> <p>This doesn't work though. Basically this is what I want to do: If no email address was entered or if it was entered incorrectly, set a variable called $email_error to be true. Then check for that variable, and if it's true, then remove the $phoneError part of the $errors variable.</p> <p>Man I hope I'm making some sense here. Does anyone know why this doesn't work? It reports all errors if all fields are left empty :(</p> <p>Thanks! Amit</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.
