Submit form after (ajax) validation

Submit form after (ajax) validation

Hello,

I've a form. Before submit this forum i have to check if there are uploaded pictures for this form. I check the pictures with ajax. If there are no pictures the must come a alert (see below) otherwise the form must bu submitted with a post (regular submit, no ajax or something). It's working fine but only the formsubmit don't work. Someone who know this 'problem'?

<script type="text/javascript">
$(document).ready(function(){

    $("#submit").click(function(){
        $.post(
            "/ajax-check-pics.php?id='.$id.'",
            $("#ajax-form").serialize(),
            function(data){
              if (data.message == 0) {
                alert("No pictures");
              }
              {
                $("form").submit();
              }
            },
            "json"
        );
        return false;
    });
});
</script>
