[RESOLVED] form email validation question

[catlikethief]

this is my first post, so i'm not sure if something like this has been answered before, so sorry if this is a repost.

what i'm trying to do is have a div become visible on an invalid form entry.

here is the code that i have:

function validate(c_form,email) {
	
	var reg = /^([A-Za-z0-9_\-\.])+\@([A-Za-z0-9_\-\.])+\.([A-Za-z]{2,4})$/;
	var address = document.forms[c_form].elements[email].value;
	if(reg.test(address) == false) {
	  	function ShowPopup(hoveritem) {
			
			hp2 = document.getElementById("hoverpopup2");
			if (hp2.style.display!= "block") {
			
			// Set popup to visible
			hp2.style.display = "block";
			}
		}
	  	return false;

            }
            return valid;
}

and here is the div:

<div id="hoverpopup2"><div id="message"><?php echo $message ?></div></div>

any ideas of why this isn't working?

Try it like this:

function validate(c_form,email) {
	
    var reg = /^([A-Za-z0-9_\-\.])+\@([A-Za-z0-9_\-\.])+\.([A-Za-z]{2,4})$/;
    var address = document.forms[c_form].elements[email].value;
    var hp2 = document.getElementById("hoverpopup2");
    if(reg.test(address) == false) {
        hp2.style.display = "block";
        return false;
    }
    hp2.style.display = "none";
    return true;
}

thanks, man; worked perfectly.

another question - how would i get a div to display if the form was valid and sent?

[Fang]

By having the server program reload the document with a div displayed

[catlikethief]

so can you tell me if i'm doing this correctly at all. i'll show you some of the code, and if you need more, let me know.

This is what i have inside the php for when the form goes through:

    unset($_POST);
        echo "<script type=\"text/javascript\">\n";
        echo "var hp5 = document.getElementById(\"hoverpopup3\");\n";
        echo "hp5.style.display = \"block\"; }\n";
        echo "</script>"; 

it doesn't seem to be working, though, so any help would be nice.

thanks.

Wait for the document to load

echo <<<HDOC
<script type="text/javascript">
window.onload=function() {
var hp5 = document.getElementById("hoverpopup3");
hp5.style.display = "block";
};
</script>
HDOC;

it doesn't seem to be working, i get a parse error stating:

Parse error: syntax error, unexpected $end in process-form.php on line 51.

here is the php file that i'm using, maybe that will help.

<?php
    function is_valid_email($e) {
        if(eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})$", $e)) {
            return true;
        }
        else {
            return false;
        }
    }
    import_request_variables('pg');
    $message = 'Please fix the following error(s): ';
    $valid = true;
    if (!is_valid_email($email)) {
        $valid = false;
        $message .= "enter a valid email address, ";
    }
    if ( empty($full_name) ) {
        $valid = false;
        $message .= 'name is required, ';
    }
    if ( $valid ) {
        $fh = fopen('new_guests.txt','a+');
        
        $comments2 = str_replace("\r\n",'<br />',$comments);        
        $content  = "$full_name\t";
        $content .= "$email\t";
        $content .= "$comments2\n";
        fwrite($fh,$content);
        
        $subject = str_replace("\r\n",'',$subject);
        $email = str_replace("\r\n",'',$email);
        $body = "Name: $full_name\n";
        $body .= "$full_name says: $comments\n";
        $body .= "\n\nIP Address: " . $_SERVER['REMOTE_ADDR'];
        mail("?@???","To my mans: $comments",$body,"From: $email\r\n");
                
        // clear the post
        unset($_POST);
                echo <<<HDOC
                <script type="text/javascript">
                window.onload=function() {
                var hp5 = document.getElementById("hoverpopup3");
                hp5.style.display = "block";
                };
                </script>
                HDOC;
    }
    else {
        $message = substr($message, 0, -2) . '.';
    }
?>

The closing identifier must begin in the first column of the line.
