The $this->config->get object is set initially from index.php file as a current setting and not as a module tracking. The $setting array passed into the index method is the one initialized whenever the current module is loaded at that point in the loop. The $setting object should be initialized automatically by ensuring that the same basic key names are being added from the admin modules before loading the array on the store-front end. Additional key names can be added along with the basic key names as there should be no problem to re-catch those additional keys by using the $setting array either. This methodology should not interfere with other modules nor with other basic key names since each $setting array are being fetched accordingly from the database.

Dedication and passion goes to those who are able to push and merge a project.

The function you are calling (resize) takes three parameters - image url, width and height. It takes this information and creates a "copy" of the original image at the dimensions specified.

Thee are several image sizes in the "settings" table any of which you can get by using the line of code suggested by UKSitebuilder.

Or, if you know the size that you want the image to be, you can use constants eg:

Code: Select all

$image = $this->model_tool_image->resize($result['image'], 250, 250);

The $setting array is loaded through the index function and contains an array of settings for that instance of the module. These are then retrieved in the front-end module controller through $setting[''SETTING_NAME']. These settings are defined in the module in the back-end (admin).

To use the image resize function, you need to load the model first:

Code: Select all

$this->load->model('tool/image');
