codeigniter-2

问题 Given the following models: Category: has_many(‘template’) Template: has_many(‘tag’, ‘procedure’) What is the most efficient way to load ALL objects related to ALL categories? For instance, I’m currently doing the following, but hopefully there is a better way: // Load all Category objects $categories = new Category(); $categories->get(); // Load all Template objects related to each Category foreach($categories as $category) { $category->templates->get(); // Load all the Tag and Procedure

问题 I'm struggling to get the CodeIgniter Image Manipulation working correctly. Either it's a bug or I'm just not seeing it. I hope someone can help me with it. Thanks in advance! On the script: I want to create thumbnails (176w x 132h). The input images are in different sizes and ratios. In order to always get this size I first resize them to fit the max width or height (depending on image orientation) and then crop in the center. I've tried to do it all in 1 method.

问题 I know I can set ion auth to login by username in the config, I also know I can set it to login by email in the config. Is there a simple way to set it it to use either automatically? 回答1: If by automatic, you mean try one and then the other to see if either gives a valid return: The login occurs in ion_auth_model line: 899 ->where($this->identity_column, $this->db->escape_str($identity)) so you could change this to do an "or" and try both columns. You would need to do this throughout the
