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.
