However, I want the button to change to a link to the user's profile if someone is already logged in. I don't know if the right way to do this is to put an

问题 I would like to be able to use OOP and create new objects in my controllers in CodeIgniter. So I need to use an autoload-function: function __autoload( $classname ) { require_once("../records/$classname.php"); } But how can I add that to CodeIgniter? 回答1: You can add your auto loader above to app/config/config.php . I've used a similar autoload function before in this location and it's worked quite neatly. function __autoload($class) { if (strpos($class, 'CI_') !== 0) { @include_once(APPPATH

If re re .load() the controller wont it re-init the object and we lose the data? Are we approaching this in the wrong way? 回答1: Store the validation messages in sessions from your controller and then show them on the corresponding view/page but

问题 I'm new to stackoverflow and to CodeIgniter and I'm currently experimenting on some simple code examples I have found on the Internet in order to get a start. The one I'm working on right now is a form which uses CI and Ajax (jQuery) along with saving the inputs of the form in a database and then display the most recent of them on the same page as the form. If I confused you it's the 4.7 application example from here. The initial source code lies here but I have modified it in order to work

问题 I have two arrays, array A contains a long list with some elements I want to remove. Array B is the full list of those elements that I wish to remove from array A. What is the most efficient way to achieve this? 回答1: array_diff is the obvious answer, but since you've asked for the most efficient way, here's a test $big = range(1, 90000); $remove = range(500, 600); $ts = microtime(true); $result = array_diff($big, $remove); printf("%.2f\n", microtime(true) - $ts); $ts = microtime(true); $map =
