IE not processing form with input type of image

[Ricky55]

Hi

 

I have a simple form that uses an image for the submit button

 

<input type="image" src="images/contactSendBtn.jpg" alt="Submit Form" name="submit" value="submit" />

 

This submit button works in all browsers but not in IE. I've read that its something to do with IE not sending the submit variable correctly and instead sending submit_x.

 

Could anyone look at my script and tell me how I need to change this to get it to work with this input type of image.

 

Thanks

 

My script

 

<?php
$after = "/contact-success.php"; 
$oops = "/contact-failed.php";

if (!isset($_POST['submit']) || $_SERVER['REQUEST_METHOD'] != "POST") {
    exit("<p>You did not press the submit button; this page should not be accessed directly.</p>");
} else {
    $exploits = "/(content-type|bcc:|cc:|document.cookie|onclick|onload|javascript|alert)/i";
    $profanity = "/(beastial|bestial|blowjob|clit|cock|cum|cunilingus|cunillingus|cunnilingus|cunt|ejaculate|fag|felatio|fellatio|fuk|fuks|fuck|fuck off|gangbang|gangbanged|gangbangs|hotsex|jism|jiz|kock|kondum|kum|kunilingus|orgasim|orgasims|orgasm|orgasms|phonesex|phuk|phuq|porn|pussies|pussy|spunk|xxx)/i";
    $spamwords = "/(viagra|phentermine|tramadol|adipex|advai|alprazolam|ambien|ambian|amoxicillin|antivert|blackjack|backgammon|texas|holdem|poker|carisoprodol|ciara|ciprofloxacin|debt|dating|porn)/i";
    $bots = "/(Indy|Blaiz|Java|libwww-perl|Python|OutfoxBot|User-Agent|PycURL|AlphaServer)/i";

    if (preg_match($bots, $_SERVER['HTTP_USER_AGENT'])) {
        exit("<p>Known spam bots are not allowed.</p>");
    }
    foreach ($_POST as $key => $value) {
        $value = trim($value);

        if (empty($value)) {
        	if (($key != "company" && $key != "telNo"))  
        		{
            exit("<p>Please go back and complete the required fields.</p>");      
            	}
        } elseif (preg_match($exploits, $value)) {
            exit("<p>Exploits/malicious scripting attributes aren't allowed.</p>");
        } elseif (preg_match($profanity, $value) || preg_match($spamwords, $value)) {
            exit("<p>Please keep things clean, no naughty words!</p>");
        }

        $_POST[$key] = stripslashes(strip_tags($value));
    }

    if (!ereg("^[_a-z0-9-]+(.[_a-z0-9-]+)*@[a-z0-9-]+(.[a-z0-9-]+)*(.[a-z]{2,6})$",strtolower($_POST['email']))) {
        exit("<p>How can we reply if you don't provide us with a valid email address?</p>");
    }

    $recipient = "[email protected]";
    $subject = "Web Site Enquiry";
    
$message .= "Name: {$_POST['name']} \n";
$message .= "Company: {$_POST['company']} \n";
$message .= "Email: {$_POST['email']} \n";
$message .= "Tel: {$_POST['telNo']} \n";
$message .= "Message: {$_POST['message']} \n";


    $headers .= "From: {$_POST['email']}";

    if (mail($recipient,$subject,$message,$headers)) {
        echo "<meta HTTP-EQUIV=\"REFRESH\" content=\"0; url=$after\">"; 
    } else {
        echo "<meta HTTP-EQUIV=\"REFRESH\" content=\"0; url=$oops\">";
    }
}
?>

judging by the words used, im simply concerned with helping you with your secret desires.

If you know the answer please help me.

i know a work around, but the way to find out if its submit_x would be print_r($_POST) to find out what that submit comes up with, i'm pretty sure that is what happens thoough with image submits, i had this issue myself in the past.

workaround: hidden field, check for hidden field in $_POST, go from there.

Not this again.

 

The only thing the w3.org specification states is  that the x and y coordinate where the image was clicked be sent to the server. AFAIK, all browsers do this. The browsers that send the name/value pair are doing their own thing outside of the w3.org specification.

 

You can use one of the following methods to detect if a form using an image as a submit button has been submitted -

 

1) Test if $_SERVER['REQUEST_METHOD'] == "POST"

 

2) Put a get parameter with a specific name/value on the end of the URL in the action="..." attribute and test for the get variable in your code.

 

3) Put a hidden field in the form with a specific name/value and test for it in your code.

 

4) Test for either the name_x or name_y coordinate from the image - http://us3.php.net/manual/en/faq.html.php#faq.html.form-image

Cheers I used the _x method and it worked for me.
