jQueryUI .dialog("close") not working after ajax call

I'm using jQueryUI's dialog with the modal form option to open a popup form. When the user clicks a button, it submits their input to a database, and then should close the dialog. Everything is working EXCEPT the closing of the dialog. (The manual Close button works; it just doesn't automatically close after coming back from the PHP database script. Here's the script code. (I tried to bold the line that's not working; apparently you can't nest bold inside of code tags, but the line is surrounded with double asterisks to make it stand out. Those are not part of the actual code!)

<script>
    $(function() {
        // a workaround for a flaw in the demo system (http://dev.jqueryui.com/ticket/4375), ignore!
        $( "#dialog:ui-dialog" ).dialog( "destroy" );

        var name = $( "#name" ),
            email = $( "#email" ),
            company = $( "#company" ),
            plate = $( "#plate"),
            allFields = $( [] ).add( name ).add( email ).add( company ).add( plate ),
            tips = $( ".validateTips" );

        function updateTips( t ) {
            tips
                .text( t )
                .addClass( "ui-state-highlight" );
            setTimeout(function() {
                tips.removeClass( "ui-state-highlight", 1500 );
            }, 500 );
        }

        function checkLength( o, n, min, max ) {
            if ( o.val().length > max || o.val().length < min ) {
                o.addClass( "ui-state-error" );
                updateTips( "Length of " + n + " must be between " +
                    min + " and " + max + "." );
                return false;
            } else {
                return true;
            }
        }

        function checkRegexp( o, regexp, n ) {
            if ( !( regexp.test( o.val() ) ) ) {
                o.addClass( "ui-state-error" );
                updateTips( n );
                return false;
            } else {
                return true;
            }
        }

        $( "#dialog-form" ).dialog({
            autoOpen: false,
            height: 390,
            width: 350,

                    var bValid = true;
                    allFields.removeClass( "ui-state-error" );

                    bValid = bValid && checkLength( plate, "plate code", 1, 7 );
                    bValid = bValid && checkLength( email, "email", 6, 80 );
                    bValid = bValid && checkLength( company, "company", 1, 100);

        $( "#submit-plate" )
            //.button()
            .click(function() {
                $( "#dialog-form" ).dialog( "open" );

    });
</script>

Any ideas? EDITED TO ADD PHP CODE

<?php
include('../cfg/ez_sql.php');
include('../cfg/db_setup.php');

$err = false;
if (isset($_REQUEST['plate'])) {

    $raw = "INSERT INTO dot_plate_submissions (plate_code, plate_name, plate_company, plate_email) VALUES ('%s', '%s', '%s', '%s')";
    $clean = sprintf($raw,
               mysql_real_escape_string($_REQUEST['plate']),
               mysql_real_escape_string($_REQUEST['name']),
               mysql_real_escape_string($_REQUEST['company']),
               mysql_real_escape_string($_REQUEST['email']));

    //error_log("cleaned query: $clean");

   $db->query($clean);
}
else {
    $err = true;
}

if($err) {
    $return['error'] = true;
    $return['msg'] = "There was an error submitting your plate";
}
else {
    $return['error'] = false;
    $return['msg'] = "made it to php";
}
echo json_encode($return);
?>

So even if the error is false, the ajax call should still get back two pieces of data.

Change your $.ajax call to include a context so $(this) is valid in the callback:

$.ajax({
    type: "POST",
    url: "submit_plate.php",
    data: string,
    dataType: 'json',
    context: $(this),
    cache: false,
    success: function(returnData){
        if(returnData.error === false) {
            $( this ).dialog( "close" );
            } else {
                  alert("Error: "+returnData.msg);
            }
    }   
});

when you initialize your dialog do something like such:

var dialog = $( "#dialog-form" ).dialog({....});

Once you're ready to close your dialog, rather than using $(this) try:

$(dialog).dialog("close");

I've had to do this in the past in solutions I've wrote where I experienced the same issues
