Want to have an e-mail check in this script

[shinytoygun]

Hey Everyone,

 

I have a question, I have a script that allows me to receive messages from my visitors on my site. As it is, its a great script (has captcha protection and works like a charm) but I want to modify it and add an additional check on it. As it is, it notifies my users when a required field is empty (this happens when one hits the submit button) but I also want to it to check an input field, or the email field really. I want it to only accept e-mails from a specific domain (like for example, if the email address field doesnt contain the words @phpfreaks.com I want it to display a notification similar to the empty field one when a user hits submit)

 

In appreciation, please note that I will compensate and deposit a little something via Paypal to a user that might help me accomplish this as my way of saying thanks.

 

Here's the script:

<?php

if($image_verification) 
{
require_once("{$path_escape}captcha.cls.php");
$captcha = new captcha();
}

$data = array();

if ($_POST['do'] == "post")
{
$data = $_POST;

$value_missing = FALSE;
if(!$data['name'] || !$data['email'] || !$data['message']) {
	$err .= "• $lang[ERROR_POST_FILL_ALL]<br>";
	$value_missing = TRUE;
}
if($image_verification && !$captcha->verify($_POST['captcha']))
	$err .= "• $lang[ERROR_IMAGE_VERIFICATION_FAILED]<br>";
if($data['email'] && !ValidateEmail($data['email']))
	$err .= "• $lang[ERROR_INVALID_EMAIL]<br>";

}

if ($_POST['do'] == "post" && !$err)
{
if($image_verification)
	$captcha->resetCookie();

$msg = "";
$msg .= "Name: ".$data['name']."\n";
$msg .= ($data['phone']) ?
	"Phone: ".$data['phone']."\n\n" : "";
$msg .= "Message:\n~~~~~~~~~~~~~~\n";
$msg .= $data['message'];

if (!@sendMail($site_email, $contact_form_subject, 
		$msg, $data['email']))
/* End Version 5.1 - Send mail using SMTP */
{
	if($debug) echo "<p>Error sending contact message.</p>";
	else die("Error sending confirmation mail");
}
else
{
	header("Location: /index.php?view=thanks");
}
}

?>
<div>

    <h2>Contact Us</h2>
    
    <a href="index.php?cityid=<?php echo $xcityid; ?>"><?php echo $lang['BACK_TO_HOME']; ?></a>

<br><br>Thank you so much for visiting <?php echo $site_name; ?>. Please write to us by filling out the form below.<br><br>

<?php if($err) echo "<br><div class=\"err\">$err</div><br>"; ?>

<form method="post" name="frmPost">
<table class="postad" border="0" cellspacing="0" cellpadding="0">

	<tr>
		<td colspan="2">
			<b>Name:</b> <span class="marker">*</span><br>
			<input name="name" type="text" size="60" maxlength="100" value="<?php echo $data['name']; ?>">
		</td>
	</tr>

	<tr>
		<td colspan="2">

			<b>Email:</b> <span class="marker">*</span><br>

			<textarea name="message" cols="78" rows="10" ><?php echo $data['message']; ?></textarea><br>

		</td>
	</tr>

	<?php
	if(!$in_admin && $image_verification)
	{
	?>
		<tr><td colspan="2"> </td></tr>
		<tr>
			<td valign="top"><b><?php echo $lang['POST_VERIFY_IMAGE']; ?>: <span class="marker">*</span></b></td>
			<td>
			<img src="captcha.png.php?<?php echo rand(0,999); ?>"><br>
			<span class="hint"><?php echo $lang['POST_VERIFY_IMAGE_HINT']; ?></span><br>
			<input type="text" name="captcha" value="">
			</td>
		</tr>

	<?php
	}
	?>

</table>
<input name="do" type="hidden" id="do" value="post">
<button type="submit" class="btn_post">SUBMIT</button>
</form>

</div>

 

Lastly and for fyi really, the notification im gonna use in my language file for this email error will be

 

$lang[ERROR_USE_EMAIL_FROM_THIS_DOMAIN]

 

so you can be bring it up like this  if you know what I mean

 

$err .= "• $lang[ERROR_USE_EMAIL_FROM_THIS_DOMAIN]<br>";

 

But ya, any help will greatly be appreciated.

 

Thanks and god bless
