    <p>I'm trying to create a dynamic if-statement. The reason I want to do this, is because I need to check server-sided whether inputfields match my regex and are not empty. However, some of my inputfields can be removed in my CMS, meaning there would be more/less inputfields accordingly.</p> <p>Ideally I would add variables in my if-statement but I'm not 100% sure if that's allowed, so perhaps I would need an other way to solve this problem. Here's what I tried:</p> <pre><code>if ($f_naw['streetname'] == 1) { $streetname= $_POST['streetname']; //Used in INSERT query $cstreetname = " || $_POST['streetname'] == ''"; //Used to check if field is empty $pstreetname = " || !preg_match($streetnameReg,$_POST['streetname'])"; //Used to check if it matches my regex } else { //These variables define variables if inputfields are not shown $streetname= ''; //No streetname means it's excluded in INSERT query $cstreetname = ''; //Not needed in check $pstreetname = ''; //Also not needed in check } // more of these if/else statements if ($_POST['firstname'] == '' || $_POST['lastname'] == '' || $_POST['email'] == '' $cstreetname $cpostalcode $chometown $ctelnr $csex $cdateofbirth) { echo 'One of the fields is empty.'; header('refresh:3;url=index.php'); } else { //Regex check, after that more code } </code></pre> <p>My idea was to check if a specific field is shown on the front-end and in that case I'm creating some variables that I want to paste in my if-statements.</p> <p>I'm getting an error saying Server error meaning my php-code would be invalid.</p> <p>Is it even possible at all to make a dynamic if-statement? If yes, at what part am I failing?</p> <p>Help is much appreciated! Thanks in advance.</p>

    1. COit sounds like you have overlooked a beautiful construct that we like to call an [array](http://php.net/manual/en/language.types.array.php).

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.
