function prob

[techmeister]

Hi all:

My email checking function goes like:
//function that checks for valid email address:
function check_email($email) {
if (ereg("^.+@.+..+$", $email)) {
return $email;
}
else {
$errormsg = "<p>Email address is invalid!</p>";
}
}

It works fine if the error line is echoed, but I want to set it to a variable: '$errormsg'
where I already have a call to echo: $errormsg on every page that needs it.

The email checking function is an include file, and all I want to do is pass: '$errormsg'
to the page as if the function were placed directly within that script.

Real basic stuff I realise, but sometimes it's just this sort of thing that stumps you the most!
If anyone can help me I'd be best pleased! :-)

Cheers.
Russ

okay. it's pretty simple. and i think this is what the problem is so let me know if i don't understand you. in the function, if the email is valid it is returned. if it is not nothing is returned. just replace your else statement in the function with this:

else {
$errormsg = "<p>Email address is invalid!</p>";
return $errormsg;
}

Chris, Hi there:

Well it don't work! here is the function:
function checkEmail($email) {
if ((empty($email)) || (!(ereg("^.+@.+..+$", $email)))) {
$error = "<p>Email address has been ommitted or is invalid!</p>";
return $error;
}
else {
return $email;
}
}

The function is called from another page thus: include("bin/includes/functions.php");

if($submit) {
checkEmail($email);
}
<?php echo"$error"; ?> //Echoed within HTML

In the function using: echo "<p>Email address has been ommitted or is invalid!</p>"; echoes the error message to the top left of the screen, I want it to display within the HTML, so I thought:

$error = "<p>Email address has been ommitted or is invalid!</p>"; in the function would be fine but it does nothing! What's wrong with it do you think?

Cheers.
