Question

I am using swfupload plugin. When I am trying to upload an image I want to pass two parameters but the parameters are not being passed.

                 var id1='g';
                var opt1='g';
       function getValues()
                {
                    id1 = $("#id").val();
                    opt1=$("#opt").val();
                    return id1.concat(opt1);
                }

             $(document).ready(function(){

             alert(getValues()); // Here coming

            $('#swfupload-control').swfupload({
                upload_url: "upload-file.php?para=getValues()",//Here not coming
                file_post_name: 'uploadfile',
                file_size_limit : "8024",
                file_types : "*.jpg;*.png;*.gif",
                file_types_description : "Image files",

Answer 1

You have your function call in a string. You need to break the string and concatenate the function’s results onto your string.

upload_url: "upload-file.php?para=getValues()"

becomes:

upload_url: "upload-file.php?para=" + getValues()
