保存多个选择输入

Question

I have model for

• user(id,name)
• section(id,name)
• section_users(id,user_id,section_id)

The admin adds all the users and sections separately. Once theses are added I want the admin to selects the section and add all the users in it in section_users

---

I have a select input with multiple set to true. How do i save this data the cakephp way along with validation.

<?php echo $this->Form->input("section_id"); ?>
<?php echo $this->Form->input("user_id", array('multiple'=>'checkbox')); ?>

This generates

Array
(
    [section_id] => 1
    [user_id] => Array
        (
            [0] => 3
            [1] => 4
        )

)

I know i can loop and convert to this and use saveAll or saveMany but what is the cakephp way/right way to do it.

Array
(
    [0] => Array
        (
            [section_id] => 1
            [user_id] => 3
        )
    [1] => Array
        (
            [section_id] => 1
            [user_id] => 4
        )

)

Answer 1

CakePHP has the saveMany function, as mentioned in the documentation:

Model::saveMany(array $data = null, array $options = array())¶
