Adding forced preview to node and change submit button value in Drupal?

Question

This question is two-fold:

1. Is there any way to force a user to first preview a SPECIFIC node before submitting it? i.e. Not all nodes using /admin/content/node-settings ... but only ONE specific node.
2. Is there any way to change the labels to instead of saying "submit" and "preview", rather say "Process" and "Review"?

Answer 1

You can change whether previewing before posting is required at /admin/content/node-settings (Drupal 6).

As for changing the button text, you'd probably have to do that with either a code hook on the form, or somewhere in your theme.

Answer 2

The basic answer to both questions is hook_form_alter(). You'd need to check the $form_id parameter to determine if you are on a node edit form (they get the id [contenttype]_node_form, see the first line of the example implementation on the API documentation page for a way to trigger for all content types).

For your need 1, you'd check $node->nid to see if it is your specific node. If so, you'd alter the forms submit button definitions '#access' entry to disable it, if you're not on a preview page (see the node_form() function from the node module on how Drupal does this - pretty far to the end of the function).

For your need 2, you'd simply change the '#value' entries of the submit and preview button definitions in the $form array.
