function hook_user_presave

You are here

7 user.api.php hook_user_presave(&$edit, $account, $category)
8 user.api.php hook_user_presave($account)

A user account is about to be created or updated.

This hook is primarily intended for modules that want to store properties in the serialized {users}.data column, which is automatically loaded whenever a user account object is loaded, modules may add to $edit['data'] in order to have their data serialized on save.

Parameters

$edit: The array of form values submitted by the user. Assign values to this array to save changes in the database.

$account: The user object on which the operation is performed. Values assigned in this object will not be saved in the database.

$category: The active category of user information being edited.

Comments

This thing does not work like hook_node_presave. I had to save the user profile form twice for the changes to take effect. Had to resort to using hook_user_profile_submit and user_save() to populate a field so the user would not have to do it. Crazy. I believe in Drupal 8 users will be entities too so maybe it will work the same way then.

If I am wrong and something else must be causing the problem for me then feel free to say so!

worked for me.

function pp_user_customizations_user_presave(&$edit, $account, $category) {
  $grade_level = $edit['field_grade_level']['und'][0]['value'];
  if($grade_level != "no"){
    $edit['field_title']['und'][0]['value'] = "user_title";
  }
}

Use the following snippet if you want to know if an user is being created :
<?php if ($account->is_new){ //Do things } ?>
