I had a problem with updating data in a loop, during the update, the assoc. HABTM data is wiped in the join table. I was led back to the Cookbook where I found this is default behaviour (last section, this page http://book.cakephp.org/view/1034/Saving-Related-Model-Data-HABTM).
What isn't clear (or I can't figure out) is how to prevent this default behaviour. I have this method in my controller: function up($id = null, $order = null) { if (!$id or !$order) { $this->Session->setFlash(__('Invalid id or order number', true)); $this->redirect(array('action'=>'index')); } // Create an array of the image table contents of IDs and Orders. $conditions = array( //'fields' => array('id','order'), 'order' => 'Subcategory.order ASC' ); $subcategories = $this->Subcategory->find('all', $conditions); // Set the direction for the image to travel (up) $delta = -1; // index = the array item you want to move // delta = the direction and number of spaces to move the item. $index = $order -1; $index2 = $index + $delta; // Move the elements in the array $temp_item = $subcategories[$index2]['Subcategory']['order']; $subcategories[$index2]['Subcategory']['order'] = $subcategories[$index]['Subcategory']['order']; $subcategories[$index]['Subcategory']['order'] = $temp_item; // Write it all back to the database foreach ($subcategories as $subcategory): $this->Subcategory->create(false); $this->Subcategory->save($subcategory); endforeach; $this->redirect(array('action' => 'index')); } You can see I've commented out fields in the conditions in the vain hope that all the data would be updated. However the behaviour is the same, gone is the contents of my join table. I've been shown SortableBehaviour, which I expect will eventually replace my less esteemed code (I'm a newbie), but I want to fill the gap in my knowledge and have this work first. Any assistance would be gratefully received.
