[RESOLVED] String help needed

[himandher]

Hi all

I am needing to parse an alpha num string for validation. 😕

The string needs to always begin with one (1) alpha character (A - L only) then be followed by eight (8) numerical characters (0 - 9) and then end with one (1) alpha character (A - Y but not allow the O).

If the string is not in this format I need to kick it back to the form for the user to fix the string.

Any ideas on the best way to validate this type of string.

Thanks in advance for any and all help.

use a regular expression. if it fails, do a redirect back. For help with regexes, there are oodles of tutorial sites...and the manual even has a decent section

this is what I have found but is there a better expression then this?
(ereg ("([a-lA-L]{1,1})([0-9]{8})([a-yA-Y]{1,10})", $serialnumber, $regs))

use a regular expression.

pretty darn close I think. although you seem to have forgotten that last part abount not allowing the O on the end. OTher than that, it looks good to me

Thanks Max

I will use the ereg expression since it is working and there are no other ideas.
