问题 I'm using REST Server in codeigniter, and the way to use is that then in my app in all my controllers I must write this line on start: require APPPATH . '/libraries/REST_Controller.php'; Does anyone know how to autoload this REST_Controller and to avoid this line in all my controllers? I don't want to use require. Thank in advance 回答1: You can achieve this through Codeigniter 's autoload configuration. Edit your project's autoload.php which is located in directory YourProject/application

问题 I’m using insert_batch() to mass insert 10000+ rows into a table in a database. I’m making some tests and I have noticed that sometimes all the 10.000+ rows are getting inserted correctly but in some occasions I miss 100+ rows in my table’s total count. The field data in the records I have are ok as I'm using the same data for each of my tests and most of the times I have no problem. For example I tried 20 times to insert the same data into my database and at 19 times all rows will be

问题 Fairly straightforward question: I know that Codeigniter is a MVC framework - however what design pattern is Codeigniter using? From first look it seems like Facade, but I could be wrong. Edit: Perhaps I should describe Codeigniter for those who don't use it. In Codeigniter you have a concept of a Controller and a Model, which each has their own separate folder. In each of the folders you create a file: cart.php: <?php class Cart { //... } ?> Then you can also have a model: <?php class User {

问题 I am using the Email class in Codeigniter, and in the manual I see that there are 3 protocols that can be used: mail, sendmail and smtp. What is the dfiference between mail and sendmail? Is it true that using mail protocol will have a higher chance of having the domain marked as spam? 回答1: If you're using *nix, chances are mail() and sendmail() are identical. mail() will still use sendmail, but it passes any arguments you have defined in your php.ini. The bigger difference is between SMTP and

问题 Logically in SQL we can delete data from tables with JOINS e.g. DELETE clb_subscriber_group_mapping .* FROM clb_subscriber_group_mapping INNER JOIN clb_driver_group ON (clb_driver_group.id = clb_subscriber_group_mapping.driver_group_id) INNER JOIN clb_company ON (clb_company.id = clb_driver_group.company_id) WHERE clb_company.id = 256 AND clb_subscriber_group_mapping.subscriber_id = 1784; What will be the CodeIgniter equivalent of above query? Does CodeIgniter support Delete query with joins?
