Need Help With Email Script?

Question

In My script, i need to validate whether or not all the text boxes are filled out. And if they arent, i want some sort of message or for it to go back, it really doesnt matter to me as long as it doesnt send and i can echo a message saying something like please be sure to fill out all fields.

Also, i want in the From Section to Make sure the user puts the @ symbol in the textbox, because like i said, its an email form and if there isnt an @ symbol it says its from the website. so i just need the @ symbol to be there or else it echos something like please check your from email address

If it helps, my variables are:

$to

$subject

$message

$from

then in the part that actually sends, i have

$headers = "From: $from\r\n";

mail($to,$subject,$message,$headers);

$theresults = (the rest)

<script type='text/javascript'>

function emailValidator(elem, helperMsg){

var emailExp = /^[\w\-\.\+]+\@[a-zA-Z0-9\.\-]+\.[a-zA-z...

if(elem.value.match(emailExp)){

return true;

}else{

alert(helperMsg);

elem.focus();

return false;

}

}

</script>

<form>

Email: <input type='text' id='emailer'/>

<input type='button'

onclick="emailValidator1(document.get... 'Not a Valid Email')"

value='Check Field' />

</form>

Using this javascipt will be better.

This will match what you said.

If people did not put @ It will make a pop up to tell them "Not a Valid Email'.
