问题 I'm working on a PHP(CodeIgniter)/MySQL application that allows users select when their blog post will be published. How I have designed it to work so far is as below: User sets the timezone in his/her profile. User sets the publish date of the blog post. This date/time is assumed to be based on user's timezone. Based on user's timezone, the publish date is converted to UTC (00:00). The converted date is stored as DATETIME in mysql. Server frequently converts the stored DATETIME values to

问题 How can I make the financial_year field as unique using Codeigniter Dbforge migration? function up() { $this->dbforge->add_field(array( 'id' => array( 'type' => 'INT', 'constraint' => 11, 'unsigned' => TRUE, 'auto_increment' => TRUE ), 'financial_year' => array( 'type' => 'VARCHAR', 'constraint' => 20 ), 'start_date' => array( 'type' => 'DATE' ), 'end_date' => array( 'type' => 'DATE' ), 'status' => array( 'type' => "ENUM", 'constraint' => "'Active','Inactive'", 'default' => "Active" ),

问题 I've created a "validation helper" that was supposed to have all my custom validation rules. The problem is that when I use them in my form validation, they seem to be ignored. If I move the functions in the controller that is doing the form validation, everything works like a charm. My validation helper is autoloaded. Is there any reason why I can't seem to use these validation functions if I put them in a helper? Thanks. 回答1: A function in a helper and a controller are different obviously.

问题 I have a javascript code that needs localisation, ie. function js_proc() { var some_data = 'this text needs to be translated dynamically at runtime'; } So I re-wrote like this: function js_proc() { var some_data = <?php echo $this->lang->line('some_data_id'); ?>; } In the view, I wrote the js link like this: <script type="text/javascript" src="www.domain.com/codeigniter/get_js/file-1/"></script> which calls the function get_js() in the controller. The idea is to have the get_js() function

问题 How can I implement dynamic subdomains in codeigniter with .htaccess ? 回答1: Make sure that subdomains are enabled on your site. When you enter test.yoursite.com it should take you to the welcome page of your site. If instead it gives DNS lookup error then it means subdomains is not enabled on your site. To enable subdomains on your site add *.yoursite.com entry to the DNS Zone records. Second insert the following code in your .htaccess file and replace yoursite appropriately. <IfModule mod

问题 I'm using codeigniter and most of the time use active record for my queries (which automatically escapes them), but this query doesn't seem to fit neatly into it because of the variable. So I need to figure out how to escape the query manually. Codeigniter docs suggest escaping the queries this way: $sql = "INSERT INTO table (title) VALUES(".$this->db->escape($title).")"; My original query $sql = "SELECT * FROM (`user_language`) WHERE `user_id` = '{$id}'"; My escaped query $sql = "SELECT *

问题 I have created a few utility functions like one h() that acts as echo htmlentities($var) . I want theses functions to be available everywhere . so where do i put it. 回答1: As @david barker said, you might use an helper. Create a file named, for example, "site_helper", that contains all the functions. be aware you need to check if the function already exists, though, or you'll get an "function already declared" error. So, something like: file site_helper.php (in application/helpers/ ) if(
