    resolved [RESOLVED] Ajax upload image via php script

    Hi

    Ultimate Aim: To upload multiple images using ajax using a PHP script which will be fired once an image is selected and then return the resulting URL for use in rest of my JS

    http://peter-gosling.com/testupload/chooseimage.html simple form
    posts to
    http://peter-gosling.com/testupload/saveimage.php

    This PHP script below currently gets the posted image and assigns it a random number file name and echos this

    PHP Code:
    <?php
    header
    ("Access-Control-Allow-Origin: *");

    $uploaddir '/home/petergos/public_html/testupload/images/';
    $uploadfile $uploaddir basename($_FILES['userfile']['name']);
    $urlpath "http://www.peter-gosling.co.uk/testupload/images/";

    $temp explode(".",$_FILES["userfile"]["name"]);
    $newfilename rand(1,999999999) . '.' .end($temp);
    $newuploadfile $uploaddir $newfilename;
    echo 
    "<p>";

    if (
    move_uploaded_file($_FILES['userfile']['tmp_name'], $newuploadfile)) {
        
    $urlfile $urlpath $newfilename;
      echo 
    $urlfile;
    } else {
       echo 
    "Upload failed";
    }
    ?>
    What I want to do is post my image via ajax but return the value back to my js file

    I'm not certain on the CORS issue

    Here's my first attempt

    HTML

    HTML Code:
    <!DOCTYPE html>
    <html>
        <head>
    
        </head>   
        <body>
    <input type="file" accept="image/*;capture=camera" name="taskoutputfile"></input>
    
             <script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
     <script type="text/javascript">
    $("input[name=taskoutputfile]").on("change", function (){
                var fileName = $(this).val();
                console.log(fileName);
                get_image_url(fileName)
    });
    
    //UPLOAD IMAGE RETURN URL
        function get_image_url(imageurl) {
            var dataString = "url="+imageurl;
            //datastring = $("input[name=sessiontitle]").val();
            //AJAX code to submit form.
            $.ajax({
            type: "POST",
            url: "http://www.peter-gosling.co.uk/testupload/saveimage2.php",
            data: dataString,
            cache: false,
            success: function(html) {
            alert(html);
            }
            });
        }
        </script>
    </body>
    </html>
    PHP

    PHP Code:
    <?php
    header
    ("Access-Control-Allow-Origin: *");

    $uploaddir '/home/petergos/public_html/testupload/images/';
    $uploadfile $uploaddir basename($_POST['url']);
    $urlpath "http://www.peter-gosling.co.uk/testupload/images/";

    $temp explode(".",$_POST['url']);
    $newfilename rand(1,999999999) . '.' .end($temp);
    $newuploadfile $uploaddir $newfilename;
    echo 
    "<p>";

    if (
    move_uploaded_file($_FILES['userfile']['tmp_name'], $newuploadfile)) {
        
    $urlfile $urlpath $newfilename;
      return 
    $urlfile;
    } else {
       echo 
    "Upload failed";
    }
    /*
    echo "</p>";
    echo '<pre>';
    echo 'Here is some more debugging info:';
    print_r($_FILES);
    print "</pre>";
    */
    ?>
    Have attached all files

    Any help would be really appreciated

    Thankyou
