e-mail control

[ereninan]

I have a rather simpler problem but since I am new for the php I had the only choice to ask this to you.

I need to control the e-mail address entered into a form if it is in the correct format or not. you know it,shouldinclude @ etc. I know I have to use ereg bu t I don't hav ethe full idea. Also I want to raise the error statement before the page is redirected to the one written in the "action" place.

thank you

Either use this thread:

or do a search for email validation, you'll find quite a few answers!

thank you for your response but I need to know how I can use this TRUE or FALSE to raise an error signal to the user by using, for instance, Javascript etc. I know that it is not recommended to use the Javascript, but I want to inform the user before the page is redirected. A small pop-up would help me.

thank you again.

function email_check ($intext) {
$email= ereg("^[@ ]+@[^@ ]+.[^@ . +$",$intext);
if ($email) {
return TRUE;
} else {
return FALSE;
}
}

<?
if (!(eregi("([_.0-9a-z-]+@([0-9a-z][0-9a-z-]+.)+[a-z]{2,3})",$email))) {
echo "$email is invalid";
}
else {
echo "$email is valid";
}
?>

PHP is a server side lanquage..therefore if you want it checked on the client side you will need to rely on javascript. Why not let the page be submitted, checked, and if bad email redirect back to the calling page with an error code set. The script on that page can then throw up the bad-email warning.
