preg_match problem

[jason360]

Anyone know why my preg_match is being triggered by this term: 3D Hobby Shop

 

To me it should allow letters and numbers etc.

 

My php:

if(preg_match('/[^a-z0-9\-\_\,\!\?\+\ \.]+/i',$_POST['title']))
			{
				$err[]='<p class="error" style="color: #ed1c24;">Your Title contains invalid characters!</p>';
			}

UPDATE:  I realize it was this term triggering my preg_match:  42" AJ Slick

 

How can I get it to accept " ' and + 

 

 

This is what I am using now:

if(preg_match('/[^a-z0-9\-\_\,\!\?\+\"\'\ \.]+/i',$_POST['title']))
			{
				$err[]='<p class="error" style="color: #ed1c24;">Your Name contains invalid characters!</p>';
			}

That last one seems to be working for me. The if() condition is returning false as the string does not contain any characters outside the ones contained in the regular expression. Although that can be cleaned up a bit by using the \w wildcard which includes a-z, A-Z, 0-9 and _ (underscore).

<?php
 
$_POST['title'] = '42" AJ Slick';
 
if(preg_match('#[^\w\-\,\!\?\+\"\'\ \.]+#',$_POST['title']))
{
    echo "error";
    $err[]='<p class="error" style="color: #ed1c24;">Your Title contains invalid characters!</p>';
}
else
{
    echo "OK";
}
 
//Output: OK
 
?>

Thanks for the prompt reply Psycho.  I used your wildcard clean up and also found my problem.  When being posted I was getting \" instead of just \. 

 

Used stripslashes function.  Working like a charm now.

 

I couldn't figure it out...I felt like i was on crazy pills...haha

 

Thanks again!
