Bosh.

Answer 2

There's validation that an email address is an email address using regular expressions, confirmation that an email address actually belongs to who entered it by using a double opt in system, and a way to check if an email address actually exists. I can't help you with this in PHP, but if you advise exactly what you want, no doubt someone will.

Answer 3

You can use regular expressions to check the syntax of the email. Don't use JavaScript, since you never know if the client has javascript enabled or not. Here is how to do it in PHP (assuming that the email address is stored in the variable $f_email):

if(eregi("^[_a-z0-9-]+ (\.[_a-z0-9-]+)*@[a-z0-9-]+ (\.[a-z0-9-]+)*(\.[a-z]{2,3})$", $f_email) == FALSE)

{

    //Invalid email, notify the user

}

else

{

    //Valid email, send it

}



This will check to see whether or not the email address uses the syntax "[e-mail]" and checks for invalid characters. (NOTE: remove the spaces after each + character).



If you want to check whether or not the email entered actually belongs to a person (and is not fake), you will need to send a confirmation message to the address.

Its better to use Javascript email validation script instead of PHP..... bcoz javascript will not submit form unless value email entered ... with PHP validation script once the form will be submitted then it will check and use have to go back and re-enter .... here is javascript validation code.





PUT the following between your









then after pasting above code in your head .... adding the following in your form tag



onSubmit="return checkForm();"



e.g. in the following line

onSubmit="return checkForm();"

action="register_user.php" method="post">



hopes this detailed reply will help you..



after this when you will submit form if the email will not be valid it will popup alert box and will not submit form untill user will not enter correct email



Cheerz...
