PHP Validation
Hello,
I want to validate 4 text boxes(in a html form) to prevent users from keying in certain words. I’m using the code below to validate 1 text box & the code works fine. How do I use the same code to validate all 4 text boxes instead of re-writing the code 4 times?
My code:-
[code=php]if (in_array(strtoupper($_POST[‘Text_Box_1’]), array(’03-‘, ’04-‘, ’05-‘, ’06-‘, ’07-‘, ’08-‘, ’09-‘, ‘012’, ‘013’, ‘016’, ‘017’, ‘019’, ‘E10’, ‘E20’, ‘E30’, ‘RM1’, ‘RM2’, ‘RM3’, ‘RM4’, ‘RM5’, ‘RM6’, ‘RM7’, ‘RM8’, ‘RM9’, ‘012-‘, ‘013-‘, ‘016-‘, ‘017-‘, ‘019-‘))) die(‘This keyword is disallowed. Please click the BACK button of your browser & change your search criteria to something else. Thanks :-)’);
The names of my text boxes are:-
Text_Box_1
Text_Box_2
Text_Box_3
Text_Box_4
Thanks a lot for your assistance.

$valid = array('03-', '04-', '05-', '06-', '07-', '08-', '09-', '012', '013',
'016', '017', '019', 'E10', 'E20', 'E30', 'RM1', 'RM2', 'RM3',
'RM4', 'RM5', 'RM6', 'RM7', 'RM8', 'RM9', '012-', '013-',
'016-', '017-', '019-');
foreach(array($_POST['Text_Box_1'], $_POST['Text_Box_2'], $_POST['Text_Box_3'], $_POST['Text_Box_4']) as $field)
{
if (in_array($field, $valid ))
{
die("The keyword '$field' is disallowed. Please click the BACK button of your browser & change your search criteria to something else. Thanks :-)");
}
}
