function confirm_form

Output a confirmation form

This function returns a complete form for confirming an action. A link is offered to go back to the item that is being changed in case the user changes his/her mind.

If the submit handler for this form is invoked, the user successfully confirmed the action. You should never directly inspect $_POST to see if an action was confirmed.

Parameters

$form: Additional elements to inject into 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>?").

$path: The page to go to if the user denies the action. Can be either a drupal path, or an array with the keys 'path', 'query', 'fragment'.

$description: Additional text to display (defaults to "This action cannot be undone.").

$yes: A caption for the button which confirms the action (e.g. "Delete", "Replace", ...).

$no: A caption for the link which denies the action (e.g. "Cancel").

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

Return value

The form.
