How to set number for maximum recipients?

Not sure how to do that - I did not think there was an artificial limit placed on the number of recipients yet?

For now you can try #398916: Remove hook_form_alter in favor of a more flexible privatemsg_new form which will allow for programmatic insertion of user names as that may be easier than writing out a list of 80 odd names, but we also need to figure out some sane manner to send messages to roles/groups without resorting to sending the messages individually - imagine a site where a person sends a message to the authenticated role...

its not directly linked, but it allows you to go to "messages/new/1,2,3,4,5,6,7,...,99" to have all those prefilled as recipients - just a possible convenience.

As for setting the maxlength without editing the module, hook_form alter would be the right way as Berdir mentioned in the other issue.

Setting the correct category, this is a new feature, not a support request.

Current behaviour is wrong - by default textfield is limited by 128 so this limit actualy to 8-9 usernames.

Suppose for D7 we can make a setting for recipients limit and use ajax to replace textfield with updatable widget so it make easy integration with realname and other contrib

subscribing, i would like to limit number of recipients vs characters.

For anyone stumbling across this who's unfamiliar with hook_form_alter, here's a code example for setting a new limit on characters (not recipients):

function YOUR_CUSTOM_MODULE_NAME_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 'privatemsg_new':
      // Example: Set the maximum length of the 'recipient' field to 10000 characters.
      $form['recipient']['#maxlength'] = 10000; // New limit is 10,000.
      
   break;
  }
}

That comment is just plain wrong because #maxlength defaults to 128. To not hardcode it, it needs to be set to 0.

To limit the number of recipients, use privatemsg_limits.module.

Patch is for 6.x-2.x, please test.

Ok, it's a bit more complicated than that.

#maxlength must be explicitly unset in an #after_build function. This should do the trick.

Should this have been committed to 7.x-1.x as well? Might prevent things like this duplicate when the next 7.x-1.x release rolls out #1822330: How to increase the Recepient field limit? (128 Chars limit).
