    <p>I'm learning PHP and I'm trying to write a simple email script. I have a function (checkEmpty) to check if all the forms are filled in and if the email adress is valid (isEmailValid). I'm not sure how to return true checkEmpty funciton. Here's my code:</p> <p>When the submit button is clicked:</p> <pre><code>if (isset($_POST['submit'])) { //INSERT FORM VALUES INTO AN ARRAY $field = array ('name' =&gt; $_POST['name'], 'email' =&gt; $_POST['email'], 'message' =&gt; $_POST['message']); //CONVERT ARRAY KEYS TO VARIABLE NAMES extract ($field); checkEmpty($name, $email, $message); function checkEmpty($name, $email, $message) { global $name_error; global $mail_error; global $message_error; //CHECK IF NAME FIELD IS EMPTY if (isset($name) === true &amp;&amp; empty($name) === true) { $name_error = "&lt;span class='error_text'&gt;* Please enter your name&lt;/span&gt;"; } //CHECK IF EMAIL IS EMPTY if (isset($email) === true &amp;&amp; empty($email) === true) { $mail_error = "&lt;span class='error_text'&gt;* Please enter your email address&lt;/span&gt;"; //AND IF IT ISN'T EMPTY CHECK IF IT IS A VALID ONE } elseif (!isValidEmail($email)) { $mail_error = "&lt;span class='error_text'&gt; * Please enter a valid email&lt;/span&gt;"; } //CHECK IF MESSAGE IS EMPTY if (isset($message) === true &amp;&amp; empty($message) === true) { $message_error = "&lt;span class='error_text'&gt;* Please enter your message&lt;/span&gt;"; } } // This function tests whether the email address is valid function isValidEmail($email){ $pattern = "^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$"; if (eregi($pattern, $email)) { return true; } else { return false; } } </code></pre> <p>I know I shouldn't be using globals in the function, I don't know an alternative. The error messages are display beside each form element.</p>

    2. COso i declare the error message variables outside the function and pass them by this: checkEmpty($name, $email, $message, $mail_error, $message_error, etc..

    3. COYou can also pass the arguments through as an array, so instead of `checkEmpty($name, $email, $message, ...)` it could be `checkEmpty($contactArray)`

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.
