    <p>I am creating a simple contact form and the form is going through client side validation with jQuery plus server side validation with PHP in case user disables Javascript on their browsers.</p> <p>Although there are many source code examples out there that can process and display with a single page, I haven't seen many that separates them into: <strong>form.php</strong> and <strong>validator.php</strong>, for example to do such task.</p> <p>I have this <strong>form.php</strong> file that are mostly written in html for marking up the form with some php codes that will receive/display the error or success message retrieved from the <strong>validator.php</strong>. Now, the problem I am having is linking these two so they talk to each other without complaining.</p> <p>"form" attribute has the action assigned to <strong>validator.php</strong> and within <strong>validator.php</strong> I have one of the function as follows:</p> <pre><code>if (isset($error)) { $msg = "&lt;p&gt;Please enter valid information.&lt;/p&gt;"; require ("form.php"); } </code></pre> <p>And, on <strong>form.php</strong> I declared <code>require ("validator.php");</code> and using this <strong>$msg</strong> variable from <strong>validator.php</strong> to display the message but the browser complains that the $msg is undefined even though the validation had its run and has the string defined.</p> <p>By the look of it, I presume these two php files are not linked properly. Anyone has an idea to the solution?</p>

    1. COset the form action in form.php to validator.php or you have to use the ajax for that.

    2. COIf you've declared your $msg variable inside a function then it won't be available outside that function. You could declare it as a global, and then it would be available. However, the way you've linked your pages looks like it could become troublesome. You might do better to create some $_SESSION variables to handle this.

    3. COdo you require form.php in validator.php and then require validator.php in form.php? it's seems to be a loop, as **naivists** said

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.
