I am trying to append a variable on the URL through a custom submit function. Is that possible?

My issue is that I am coming to the node/%/delete from different pages. I want to modify the delete form if the user comes to it from the node/%/edit. How can I detect this?

As @Clive suggested I'll try to add a query param in the following structure:

actions (Array, 5 elements)
  #type (String, 7 characters ) actions
  submit (Array, 5 elements)
  preview (Array, 5 elements)
  delete (Array, 4 elements)
    #type (String, 6 characters ) submit
    #value (String, 6 characters ) Delete
    #weight (Integer) 15

    Don't - basing logic on referrers is hit and miss and violates a RESTful web...instead, alter the edit form and change the url of the delete link to add a URL parameter to the delete URL, then alter the delete form to check for that parameter

  • Awesome input!How can I do that? Jun 27, 2014 at 11:28
  • hook_form_alter for both, the delete link is in $form['actions'] I think. Just on mobile so can't put code samples in I'm afraid

  • Cool!How could I add the param on the above structure? Jun 27, 2014 at 11:35
  • @Clive can you explain it more, I couldn't understand, as far as I know pressing delete button from node edit form will take you to a confirmation page, which is a redirect, and nothing will be passed on to that page other than node id and destination.

You should use the hook_node_access in your custom module.

For Example -

 * Implements hook_node_access().
function MODULE_node_access($node, $op, $account) {

  if ($op == "delete") {
    // If no user object is supplied, the access check is for the current user.
    if (empty($account)) {
      $account = $GLOBALS['user'];
    // You can add your own condition check here...
    return user_access("delete content", $account) ? NODE_ACCESS_ALLOW : NODE_ACCESS_DENY;
