Checking length of field input  (See more user questions)

Hi .

Good to hear from you.

You could use the str_len() function, like so:

if(strlen($_REQUEST['field_name']) != 1){$errors[] = "Please go BACK and try again";}

Just change 'field_name' for the actual field name.

Put it after this line in the script:

$errors = array();

"str_len" stands for "string length" and that's simply what it does...checks the length of the inputed string.

Best wishes.
