    PHP Upload ! Storing Image data in MySQL

    Hello there,

    I am at my wit's end ! I have used the following script succesfully to
    upload an image to my web space. But what I really want to be able to do is
    to update an existing record in a table in MySQL with the path & filename to
    the image.

    I have successfully uploaded and performed an update query on the database,
    but the problem I have is I cannot retain the primary key field in a
    variable which is then used in a SQL update statement to ensure that I
    update the correct field in the MySQL table. I have not included the code
    for the SQL update.

    To summarise I guess what I am trying to do is create a page for updating
    produuct data on an ecommerce site. So the Promary key is the Product Number
    and I need to store the image filename in the products table.

    Any Help will be gratefuly received. I am sure this is a very very simple
    question to an experienced PHP programmer, I just cant get my head around
    it all at the minute !

    Thanks in advance Dave Griffin.

    Script:

    /*
    <readme>

    fileupload-class.php can be used to upload files of any type
    to a web server using a web browser. The uploaded file's name will
    get cleaned up - special characters will be deleted, and spaces
    get replaced with underscores, and moved to a specified
    directory (on your server). fileupload-class.php also does its best to
    determine the file's type (text, GIF, JPEG, etc). If the user
    has named the file with the correct extension (.txt, .gif, etc),
    then the class will use that, but if the user tries to upload
    an extensionless file, PHP does can identify text, gif, jpeg,
    and png files for you. As a last resort, if there is no
    specified extension, and PHP can not determine the type, you
    can set a default extension to be added.

    SETUP:
    Make sure that the directory that you plan on uploading
    files to has enough permissions for your web server to
    write/upload to it. (usually, this means making it world writable)
    - cd /your/web/dir
    - chmod 777 <fileupload_dir >

    The HTML FORM used to upload the file should look like this:
    <form method="post" action="upload. php" enctype="multip art/form-data">
    <input type="file" name="userfile" >
    <input type="submit" value="Submit">
    </form>


    USAGE:
    // Create a new instance of the class
    $my_uploader = new uploader;

    // OPTIONAL: set the max filesize of uploadable files in bytes
    $my_uploader->max_filesize(9 0000);

    // OPTIONAL: if you're uploading images, you can set the max pixel
    dimensions
    $my_uploader->max_image_size (150, 300); // max_image_size( $width, $height)

    // UPLOAD the file
    $my_uploader->upload("userfi le", "", ".jpg");

    // MOVE THE FILE to its final destination
    // $mode = 1 :: overwrite existing file
    // $mode = 2 :: rename new file if a file
    // with the same name already
    // exists: file.txt becomes file_copy0.txt
    // $mode = 3 :: do nothing if a file with the
    // same name already exists
    $my_uploader->save_file("/your/web/dir/fileupload_dir" , int $mode);

    // Check if everything worked
    if ($my_uploader->error) {
    echo $my_uploader->error . "<br>";

    } else {
    // Successful upload!
    $file_name = $my_uploader->file['name'];
    print($file_nam e . " was successfully uploaded!");

    }

    How about storing the actual image in your db? (I'm just asking here,
    hoping someone else will have views on this. Same conclusion for
    PostgreSQL?)

    I'm not primarily a using PHP/MySQL, but it's fair to assume that the
    web-server won't do a lot worse at caching image data than the file
    system? Of course there's some overhead on the db connection, but.

    Didn't bother reading the code, sorry, but your problem is simply losing
    track of some variable during page transitions while you do image
    uploads or whatever else?

    The best fix is probably storing the product id in a session variable
    while all the image upload stuff is going on.

    You could also pass it along as a parameter to any of the file upload
    pages as well, either by embedding it in the forms as a hidden field, or
    as a parameter in the urls. Problem is this would clutter up your image
    upload logic, so stick with sessions.

      I could be barking up completely the wrong tree here but is all the code
      that was here yours?

      I had something like this with a system I wrote for a customer to add
      vacancies to a table for their site. They could upload a MS Word doc with
      an application form or job description. This all worked fine with it
      putting the file name into the table.

      The problem came when they wanted to edit one. I had to look at the form
      they filled in, check to see if the 'file' field was blank or not and then
      act accordingly. I'm pretty new to PHP and it took me ages to work out.
      I'm just in the process of doing something similar for a customer who wants
      a simple photo gallery on the site with the ability to edit entries as well.

      The upshot is, the code you had was WAY ahead of my ability. If it's your
      own and you're determined to make it work then I can't help. If it's
      someone else's code and your only aim is to end up with something that will
      do what you want then I can help. My code will be a billion miles from the
      most elegant code in the world but it works for me.

      Let me know if you want what I've done.

        I wish I could say it was all my own code !! But its not, I would be very
        grateful if you could let me see your code.

        I may have confused the issue when trying to explain in my original post so
        here's a summary of what I am trying to achieve !

        I have product details stored in a table called products.

        The page I am trying to create receives the URL variable Prodcut_ID which a
        SELECT Query uses in its WHERE clause to return only the details of the
        record with the matching product_id.

        I then want to upload an image to my webspace and update a field in the
        Product table with the image filename.

        The bit I am struggling with is when the form is submitted , the image
        uploads and the page refreshes and I always loose the product_id and
        therfore my sql statement fails as it has an unaasigned variable.

        I am thinking that a session variable would do the job, but I am having
        difficulties ! doing this in PHP, as I am used to ASP. My host does not
        support ASP Upload ! Hence the reason I am using PHP.

        Any help is gratefully received !

        Dave
