At the moment I am trying to validate a form using PHP. The problem is, that even after entering something wrong, PHP interprets it as right. Obviously I don't now why, although I have an assumption. This is the code: <pre><code>if(isset($_GET['contact'])){ // Validation functions // Name function validate_name(){ $name = $_POST['customer']; if(strlen($name) > 0){ trim(mysql_real_escape_string($name)); return true; }else { return false; } } // Mail function validate_mail(){ $mail = $_POST['mail']; if(preg_match('/^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}$/', $mail) && strlen($mail) > 0){ return true; }else { return false; } } // Message function validate_message(){ $message = $_POST['message']; if(strlen($message) > 0){ trim(mysql_real_escape_string($message)); return true; }else { return false; } } validate_name(); validate_mail(); validate_message(); if(validate_name == true && validate_mail == true && validate_message == true){ echo "Ok!"; }else{ echo "Error!"; } } </code></pre> One thing I know is bad is this: <code>if(validate_name == true && validate_mail == true && validate_message == true){}</code>. But if I am not mistaken, this still works because PHP can handle something like this (PHP only gives a notice, not an error). But how to do it right, there must be a better way? The second this I found out is, that PHP basically calls the functions correct, but inside the functions the if-else is not working. Why? I don't understand this...

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.
