check for symbol in text field before $_POST

[avo]

HI All

Is it possible for you to let me know how to check for a symbol in a text field before a post
i thought i should use a wildcard and tryed

[code]<?

if ($_POST ['email'] !=@% ) {
$no_symbol = "bad;
} else {

$no_symbol = "good;
}

?>[/code]

but i was wrong only came up with errors

if someone can point me in the direction of the variable that i need to use i will it will be most appriciated..

Thank in advance.

You could do it using regular expressions and look for the @ character. I'm not good at them but I am sure someone else could enlighten both of us how to look for the @ symbol.

[code]if (strpos($_POST['email'], '@') !== false) {
    # has '@' symbol
}
else {
      # invalid email address
}[/code]

HI

Just tryed the code
but it assigns the variable to bad regardless if the @ symbols is pressent or not

[code]//check if email text filed as @ symbol pressent
if (strpos($_POST['email'], '@') !== false) {
$frm_check_email  = "good";
}
else {
$frm_check_email = "bad";
$frm_check = "bad";
}[/code]

hope you can help again

thanks.

try echoing the $_POST['email'] as a check. I get 'good' if there's an '@'.
