I have an array that is sent to my controller, such as this:

$array = array(

And I need to save the position of each item using its id. What is the best way to do this in cakePHP? I can only imagine looping an update function or pulling the entire database, changing the correct values, then saving the database. Both ideas seem very bodged.

    Ha, Cake magic to the rescue again. You don't have to tell Cake to save it by id. There's a big long amazing way Cake does this, but the short and skinny is -

    if your array contains an 'id' key, Cake presumes it is the table primary key and generates an UPDATE statement instead of an INSERT. Looks like this:

    UPDATE table as Table SET Table.position = $position WHERE = $id;

    And, Cake knows to iterate for you if you use saveAll() instead of save():


    If you have any save callbacks in your model, such as beforeSave(), you have to call them manually before calling saveAll() - they only autofire on save(), not saveAll() or updateAll().

    You'll want to top your array with the name of your model ($array['Model'][0], $array['Model'][1], etc). If you need to magically saveAll() with multiple models, you top your array with indexed keys, then model names - like $array[0]['Model1'], $array[0]['Model2']) and Cake knows to save / update the associated data for all the models in each index batch.

    Cake does ALL the legwork for you: - especially the saveAll() entry.

    • Edit - and topping your array with your model name? Cake makes that ridiculously easy, too. Check out Cake's built-in Set library for all your array / object manipulation needs.

    Have you tried CakePHP's saveAll() ? Details here.
