unwanted repeated upload - El Forum - 07-21-2010

Hi Guys,
users of my application can upload files,
but when going back the upload happens again.

Any idea how to prevent this?

Thanks in advance!

Post some code. You'll get a better response that way.

thanks for the advice, code is below.
the problem:
whenever a user removes a file and clicks the "back" button,
another file is being deleted.

this is the form used to remove files:

Code:
<form name="remove_proj_form" method="post" action="<?= site_url("site_name/remove_proj")?>">
    <input type="hidden" name="selected_proj"/>
  </form>
  <form name="remove_img_form" method="post" action="<?= site_url("site_name/remove_img")?>">
    <input type="hidden" name="selected_img" />  
    <input type="hidden" name="selected_proj"/>
  </form>


this is the link that is removing a file:

Code:
<a href="[removed]remove_img(&lt;?=$i?&gt;,&lt;?=$project['project_id']?&gt;)" style="text-decoration:none">

this is the javascript called by the link above:
Code:
function remove_proj(proj)
{
  if (!confirm("Are you sure you want to remove this project?"))
    return;
  document.remove_proj_form.selected_proj.value = proj ;
  document.remove_proj_form.submit() ;
}

thanks again!
