FN-FORUM: PHP form validation Q

date posted 5th January 2005 18:22

hi all,

i'm a total PHP newb - so wondered if someone can point in the right =20
direction like ;-)

i've cribbed this mail form from somewhere and added my own stuff - =20
thing is, it only checks for an input on each field, not what that =20
input was exactly...

ideally, it needs to kick back if letters are put in the telephone =20
field. not too concerned about other fields..

any ideas??

L.

--script follows--

function dca_mailto_form($atts)
{=09
global $sitename;
if (is_array($atts)) extract($atts);
=09
if (empty($email)) {
return 'plugin txp:dca_mailto_form needs an =
email address';
}
extract(gpsa(array(
=20
'send','sender_subject','sender_email','sender_telephone','sender_day','=20=

sender_time','sender_name','other'
)));
