Easy way to change 'save' button text?

Have a look at the examples on http://api.drupal.org/ these are a great resource.

You could always hack another module, but when you forget about it and upgrade that module, your changes are lost.

So I changed it to this:

  /**
   * Implementation of hook_form_alter().
   *
   * The function is named modulename_form_alter.
   */
  function my_hook_module_form_alter(&$form, $form_state, $form_id) {
    // Normally a switch is used because you may want to alter more than
    // one form and it is easy to add a new case for each form.
    switch ($form_id) {
      // This is our form ID.
      case 'my_new_form_node_form':
        // Our kickin' mods go here.
		$form['submit'] = array(
  		'#type' => 'submit',
  		'#value' => t('Save and add new'),
		);
     break;
  }
}

Now, it actually adds ANOTHER submit button (at the very top of the form instead of the bottom next to the existing submit button) with "Save and add new" as the text instead of just replacing the current submit button text. So it appears my code is adding new instead of modifying the existing one. I am getting closer!

I tried viewing source of the page and getting the id of the current submit button and doing something like:

$form['edit-submit']['#value'] = t('Save and add new');

but that didn't work either...

Anyone want to tell me what I am doing wrong?

TIA

This doesn't help if you only want to change the value given to buttons. You still need the function shown above (in previous posts). I'm thankful to the community for actively supporting common problems and solving most of them. I had forgotten how to get button text changed, and this thread helped.

The template.php seems the simpist method but the code gives me a white screen.

This works well if you don't mind a dirty jquery hack
$('#forum-comments #edit-submit').val('Post');

First, create the folder sites/all/modules/change_default_button_values

In that folder create 2 files:

Create one file "change_default_button_values.info" with this text

; $Id$
name = "Change Default Button Values"
description = "Custom module to change button values, such as the submit button, on Drupal's default forms and content types."
core = 6.x
package = Other

Create a second file "change_default_button_values.module" with this text

<?php
  /**
   * Implementation of hook_form_alter().
   *
   * The function is named modulename_form_alter.
   */
  function change_default_button_values_form_alter(&$form, $form_state, $form_id) {
    // Normally a switch is used because you may want to alter more than
    // one form and it is easy to add a new case for each form.
 
// Find out if I'm called and if the id is right...
//var_dump($form_id);  // Uncomment to print every form id name
    switch ($form_id) {
      case 'mytype_node_form': // The machine name of our content type, 'mytype', with '_node_form' at the end.
        //print_r($form); // Uncomment to print all form information
        $form['buttons']['submit']['#value'] = t('Post'); //wrapping text in t('text here'); code is an important security & multi-lingual coding step.
        $form['buttons']['preview']['#value'] = t('Review');
        $form['buttons']['delete']['#value'] = t('Trash');
        break;
//      case 'anothertype_node_form': // This is another form's ID.
//        //print_r($form); // Uncomment to print all form information
//        $form['buttons']['submit']['#value'] = t('Post');
//        $form['buttons']['preview']['#value'] = t('Review');
//        $form['buttons']['delete']['#value'] = t('Trash');
//        break;
  }
}
?>

Then go into your modules and enable your new module called "Change Default Button Values".

Thanks to Alan D. for the above comment with more detailed information on button names and properties, to moon.watcher for hints on more detailed button-setting code, and to Sepero whose detailed example code let me figure this out faster!

@Spineless - you're likely missing the correct form_id of the comment form.

Typically it includes your entity and content type in the form id.

You can check form_id's by writing them out inside a form_alter, e.g.

function mymodule_form_comment_form_alter(&$form, &$form_state, $form_id){
  // Print out Form_IDs
  drupal_set_message($form_id);

  switch ($form_id) {
    // Modify Article Comment Form
    case 'comment_node_article_form':
      $form['actions']['submit']['#value'] =t('comment');
      break;
  }

}
