我的表格有问题。单击submit按钮时，会弹出404错误。如果有人有任何建议，我将不胜感激。

表单的Ajax处理。进入theme的js。

<script type="text/javascript">
    jQuery(\'#BookingForm\').submit(ajaxSubmit);

    function ajaxSubmit(){
        var BookingForm = jQuery(this).serialize();
        jQuery.ajax({
            action : \'make_booking\',
            type   : "POST",
            url    : "/wp-admin/admin-ajax.php",
            data   : BookingForm,
            success: function(data){
                jQuery("#feedback").html(data);
            }
        });
        return false;
    }
</script>

PHP进入functions.php

function makeBooking(){
    global $wpdb;

    $type   = $_POST["optionsRadios"];
    $to     = $_POST["to"];
    $from   = $_POST["from"];
    $date   = $_POST["date"];
    $time   = $_POST["time"];
    $name   = $_POST["name"];
    $tel    = $_POST["tel"];
    $email  = $_POST["email"];
    $passenger = $_POST["optionsRadios2"];
    $other  = $_POST["other"];

    if( $wpdb->insert(\'Booking\',
      array(
        \'type\'=>$type,
        \'from1\'=>$from,
        \'to1\'=>$to,
        \'date\'=>$date,
        \'time\'=>$time,
        \'name\'=>$name,
        \'tel\'=>$tel,
        \'email\'=>$email,
        \'passenger\'=>$passenger,
        \'other\'=>$other
      )
    ) === FALSE ) {
        echo "Error";
    }
    else {
        echo "Submission successful, an email receipt has been sent to your email address.       
        <br> Your Booking ID is:<b>ZCA- ".$wpdb->reference . "</b>";

        //Prepare email body
        $msg = "Reference: ZCA-" . $reference . "\\nType:" . $type . "\\nFrom:" . $from .     "\\nTo:" . $to . "\\nDate" . $date . "\\nTime:" . $time . "\\nName:" . $name . "\\nNumber:" .     $tel . "\\nEmail:" . $email . "\\nPassengers:" . $passenger . "\\nOther:" . $other;
        mail("[email protected]","Booking",$msg);
        mail($email,"Zcars Global Booking","Thank you for your enquiry. We aim to deal with your request straight away." . $msg);

    }
    die();
}
add_action(\'wp_ajax_make_booking\', \'makeBooking\');
add_action(\'wp_ajax_nopriv_make_booking\', \'makeBooking\'); // not really needed

我包括了HTML表单，因为我仍然收到404错误，可能是这里有什么？
