Drupal pass argument to page

I have a custom Drupal module displaying some data in a table. Each row has a link which if clicked will delete the relevant row. Specifically, when the link is clicked it will take the user to a confirmation page. This page is really just a drupal form which says 'are you sure' with two buttons: 'Yes', 'No'. I figure I will need to pass the rowID to the confirmation page.

My question: What is the typically way to pass data to a new page in Drupal 7? I guess I could just add the rowID to the URL and use the $_GET[] from the confirmation page... I don't think this is very safe and was wondering if there was a better 'Drupal' way.

Thanks!

If the data are nodes, you can make the link node/%/delete where % is the nid. Drupal knows how to handle the delete page, as its a core path. Then, the delete confirmation follows the rest of the system and is very 'Drupal'.

I am not sure if this changed at all in Drupal 7, but this is what I did for countless modules.

You'd use something like the following

<?php
function yourmod_menu() {
// for examlple
$items['yourmod/foo/%/delete'] = array(
'title' => 'Delete a foo',
'page callback' => 'drupal_get_form',
'page arguments' => array('youmode_foo_delete_confirm', 2), // 2 is the position of foo_id
'access arguments' => array('delete foo rows'),
'type' => MENU_CALLBACK,
);

return $items;
}

function yourmod_foo_delete_confirm($form, &$form_state, $foo_id) {
// load the row
$foo = yourmod_get_foo($foo_id);

// build your form, if you need to add anything to the confirm form
// ....
// Then use drupal's confirm form
return confirm_form($form,
t('Are you sure you want to delete the foo %title?',
array('%title' => $foo->title)),
'path/to/redirect',
t('Some description.'),
t('Delete'),
t('Cancel'));

}

?>

You can look here for examples of [how core modules do it][1] (have look at node_delete_confirm)

[To see links please register here]

The simplest solution would be to use an existing module created for this purpose:

-

[To see links please register here]

(for entity references)
-

[To see links please register here]

(for node references)
-

[To see links please register here]

(for other form values)

You can configure which form values can be set from the URL, then rewrite the fields displayed in your table to generate the necessary links.
