Need help w/ error checking of text input field

I'm trying to figure out why all input is generating a "Directions not alphanumeric" error. The $subdirections variable should contain the text input:

/* Check if directions is not alphanumeric */
else if(!eregi("^([0-9a-z])+$", $subdirections)){
$form->setError($field, "* Directions not alphanumeric");
}

Thanks for any tips.

 

Works just fine on my server. Can you show us an example of input data you are testing this with ?

 

ereg has been depreciated for a while now. Use preg_match() instead for all REGEX functionality in PHP. I believe thats correct as of 5.3 (poss 5.2)

Thanks

yes use preg_match() otherwise your script looks fine

 

Thanks. Sorry about the slow response. I think the problem is whitespaces. i'll try preg_match(). I was also looking at ctype_alnum.

 

preg_match()
