I am writing a php script that lets a user choose image files on their hard drive for later upload.

When they select a file I post back to the same page and add the file path and name string to a session array.

Every time they choose a file and the php posts back to the same page, I loop through the array and draw a table that shows the images that have been picked.

Here is where I am confused:

I want a "remove" button next to each image in the table. That button would once again post back to the same page sending a variable in the query string representing the array index of that image. It would remove that index from the array and redraw the table.

I have created a working example but to do that I had to put each "remove" button in it's own form.

******************
I would MUCH rather draw the whole table in the same form. Can I make a form post back to different url depending on which button was clicked?

Thanks for your time,

hi Stanly22,

you can create a link where you add the url of the picture.
like this:
<a href="<?php print $PHP_SELF.'?picurl=url_of_the_picture';?>">delete</a>

now you can take $_GET['picurl'] and search the session array.
like this:

<?php

foreach($_SESSION as $k => $v){
   
   if($v == $_GET['picurl']){

       unset $_SESSION[$k];

       }

}

?>

after that you can call up the session array and it will show all
pictures without the one you have deleted.

That makes so much sense! Why didn't I think about that? I will try it now. Thanks.

Now, in each row of the table there is an image and the "remove" link that you helped me create. (which works great I might add)

But there is also a text box in each row. The user types something about each image in each corresponding text box which I want to add to a parallel array. (so the picture at index 'x' matches the description they typed at index 'x' of the other array)

How can I get those values into $_SESSION variables if they click on the "remove" link. I can't use the $_POST that I have been using when the page reloads.

Thanks
