Subject: Re: [PHP] preg_match array question
perhaps I am misunderstanding... I have snipit of my foreach. I have a
preg_match that checks for a valid email address. basically it just
checks
for an @ and a . When I place this in my loop all of the keys are
evaluated, so hence the name key is evaluated and thrown error because
of
the check.
To remedy this problem I took it out of the loop and it worked fine.
Ultimately I would love to keep it in the loop and throw checks for
certain
fields, but syntaxtually it doesnt work for me. Any Suggestions ?
foreach ($_POST as $key=>$value) { # Begin Foreach loop
if (empty($value)) { # Begin If
echo "$key :: Missing Data<br/>";
if (!preg_match('/([a-z0-9\-\.\#\:[EMAIL PROTECTED])/i',
$_POST["eaddy"]))
{echo $_POST["eaddy"]," is not a valid address.<br/>"; }
} # End if
else { echo "$key, ->Ok<br/>";}
} # End Foreach
