2. 5 modules/system/system.module \confirm_form()
3. 7 modules/system/system.module \confirm_form()

Generates a form array for a confirmation form.

This function returns a complete form array for confirming an action. The form contains a confirm button as well as a cancellation link that allows a user to abort the action.

If the submit handler for a form that implements confirm_form() is invoked, the user successfully confirmed the action. You should never directly inspect $_POST to see if an action was confirmed.

Note - if the parameters $question, $description, $yes, or $no could contain any user input (such as node titles or taxonomy terms), it is the responsibility of the code calling confirm_form() to sanitize them first with a function like check_plain() or filter_xss().

Parameters

$form: Additional elements to add to the form; for example, hidden elements.

$question: The question to ask the user (e.g. "Are you sure you want to delete the block <em>foo</em>?"). The page title will be set to this value.

$path: The page to go to if the user cancels the action. This can be either:

• A string containing a Drupal path.
• An associative array with a 'path' key. Additional array values are passed as the $options parameter to l().

$description: Additional text to display. Defaults to t('This action cannot be undone.').

$yes: A caption for the button that confirms the action (e.g. "Delete", "Replace", ...). Defaults to t('Confirm').

$no: A caption for the link which cancels the action (e.g. "Cancel"). Defaults to t('Cancel').

$name: The internal name used to refer to the confirmation item.

Return value

The form array.
