[RESOLVED] Help with adding characters for field validation

[genista]

Hi,

I am working on some form validation right now and I have a function that is called to check for certain characters and throw out errors if there is anything amiss. The problem I am having is trying to add comma and full stop to the list of what is acceptable, here is the code as it stands:

# a hash array of "types of data" pointing to "regexps" used to validate the data: 
    $data_types=array( 
        "email"=>$email_regexp, 
        "digit"=>"^[0-9]$", 
        "number"=>"^[0-9]+$", 
        "alpha"=>"^[a-zA-Z]+$", 
        "alpha_space"=>"^[a-zA-Z ]+$", 
        "alphanumeric"=>"^[a-zA-Z0-9]+$", 
        "alphanumeric_space"=>"^[a-zA-Z0-9 ]+$", 
        "string"=>"" 
    );  

Under alphanumeric_space I have tried to add: ,. but unfortunately this does not work like so:

"alphanumeric_space"=>"^[a-zA-Z0-9 ,.]+$",  

I have also tried:

"alphanumeric_space"=>"^[a-zA-Z0-9 \,\.]+$",  

But to no avail...

How can I make this work?

Thanks,

G

It looks correct me, how are you using it?

Ok,

Once submit is set I set up the variables, once that is done I do field validation like so:

field_validator2("enquirydetails", $_POST["enquirydetails"], "alphanumeric_space", 0, 200);

Then I check for $messages which are setup in the function:

  if(!empty($messages)){
    displayErrors($messages);
}  

    else
	{
do form processing

All of this works as intended, but now I want to add characters to the 'allowed' list in that function I am having problems....

Okay, do a simple test. Does this code output 'match' for you?

<?php
$pattern = '/^[a-zA-Z0-9 ,.]+$/';
$subject = 'this.test,works yeah';
if (preg_match($pattern, $subject)) {
    echo 'match';
} else {
    echo 'no match';
}
?>

yup I get match ok...

Therefore, the problem must lie elsewhere, possibly in the implementation of field_validator2().

Ah, I have spotted the problem and have rectified it, I used your code on what I was doing and found the issue elsewhere in the script while doing it. Thanks!
