问题 Ok, In my Codeigniter project I am passing a multidimensional array to my view. The issue I am having is access the data in the array. I use print_r and var_dump to see the array and it is being passed correctly to the view but I am having the hardest time access the data within it! I get this error message, "Trying to access parameter of non-object". Any suggestions?! Here is the controller: profile.php <?php class Profile extends CI_Controller { public function __construct(){ parent::_

问题 I have a little issue with some code that works on development but not on production. It is weird, because all the other code works (or seems to). The entire error is the following: Fatal error: Using $this when not in object context in /[snip]/application/modules/manage_plugins/models/Manage_plugins.php on line 6 A PHP Error was encountered Severity: Error Message: Using $this when not in object context Filename: models/Manage_plugins.php Line Number: 6 Backtrace: From the other similar

问题 I'm experiencing a strange problem while using CodeIgniter's Active Record class ( looks like not only that, check update at bottom of question ), and that happens only on some servers (belonging to the same provider). What happens is that the query is run only "partially", meaning that results are retrieved from mysql database, but any where or join or select clause is ignored. A simple example: $this->db->select('title,intro'); $this->db->from('content'); $this->db->where('published','1');
