PHP form validation function
- by Barbs
I am currently writing some PHP form validation (I have already validated clientside) and have some repetitive code that I think would work well in a nice little PHP function. However I have having trouble getting it to work. I'm sure it's just a matter of syntax but I just can't nail it down.
Any help appreciated.
//Validate phone number field to ensure 8 digits, no spaces.
if(0 === preg_match("/^[0-9]{8}$/",$_POST['Phone']) {
$errors['Phone'] = "Incorrect format for 'Phone'";
}
if(!$errors) {
//Do some stuff here....
}
I found that I was writing the validation code a lot and I could save some time and some lines of code by creating a function.
//Validate Function
function validate($regex,$index,$message) {
if(0 === preg_match($regex,$_POST[$index],$message) {
$errors[$index] = $message;
}
And call it like so....
validate("/^[0-9]{8}$/","Phone","Incorrect format for Phone");
Can anyone see why this wouldn't work?
Note I have disabled the client side validation while I work on this to try to trigger the error, so the value I am sending for 'Phone' is invalid.
