jquery php电子邮件表单无法区分回调

Question

I need to get this to distinguish between a successful and a failed submission.

send-email.php

$name = trim($_REQUEST['name']);
$email = trim($_REQUEST['email']);
$content = $_REQUEST['comment'];

if (eregi("",$email) || eregi("
",$email)){
 die("Why ?? :(");
}
$sitemail = "[e-mail]";
$ip='none';
$ip = getenv('REMOTE_ADDR');
if( $_SESSION['security_code'] != $_POST['security_code'] || empty($_SESSION['security_code'] ) ) {
    echo'<div class="message">The security code you entered did not match the image.</div>';
    return false;

}
else{
    //$sent=mail( $sitemail, "Message Title","From: $name 
 
 $message 

 $ip", "From: $email" );
    echo'<div class="message">Thank you for your message. We will get back to you as soon as possible.</div>';

}

Jquery:

jQuery("#contact-form").submit(function(e){
        var $form = jQuery(this),
        $msg = jQuery(this).prev('div.message'),
        $action = $form.attr('action');
        jQuery.post($action,$form.serialize(),function(data){
            $form.fadeOut("fast", function(){
                $msg.hide().html(data).show('fast');
            });
         });
        e.preventDefault();
  });

form

<div class="message"></div>

            <form id="contact-form" method="post"  action="send-email.php">
                <p class="column one-half">
                    <input name="name" type="text" placeholder="Your Name" required >
                </p>

                <p class="column one-half last">
                    <input name="email" type="email" placeholder="Your Email" required >
                </p>

                <p class="clear"><textarea name="comment" placeholder="Your Message" cols="5" rows="3" required></textarea>
                </p> 
                <p class="column one-third"><input id="security_code" type="text" placeholder="Enter Code in image" name="security_code" required></p>
                <img src="captcha/verifyimg.php?width=192&height=48" alt="Image verification" align="left" style="margin:10px;" />
                <p><input name="submit" type="submit" value="Send Message">
                </p>            
            </form>

I want to be able to get the form to stay visible if the form fails on the security_code.

So perhaps a response from the send-email.php is needed and then used with an 'if' clause. I have tried several ways to do this and couldn't even get it to distinguish between the callback results! I just seem to have gone round in circles. Any help appreciated.

can you please check this code

Jquery Code

jQuery.ajax({
            url: jQuery('form#FrmQuote').attr("action"),
            type: "POST",
            dataType: 'json',       
            data: jQuery('form#FrmQuote').serialize()+'&action=SubmitQuote',
            success: function(data){
                if(data['status']) {
                    // if it return success
                } else {
                             // if it return error
                    for(var id in data['error']) {
                            jQuery('#' + id).html(data['error'][id]);              
                    }

        $SubmitQuoteResult['error'] = $err;
    }
    echo json_encode($SubmitQuoteResult);
    exit;
    }
