Loader Class
Loads framework components.
library(mixed $library, array $params = NULL, string $object_name = NULL) : object
Library Loader
Loads and instantiates libraries. Designed to be called from application controllers.
| mixed | $library | Library name |
| array | $params | Optional parameters to pass to the library class constructor |
| string | $object_name | An optional object name to assign to |
model(mixed $model, string $name = '', boolean $db_conn = FALSE) : object
Model Loader
Loads and instantiates models.
| mixed | $model | Model name |
| string | $name | An optional object name to assign to |
| boolean | $db_conn | An optional database connection configuration to initialize |
database(mixed $params = '', boolean $return = FALSE, boolean $query_builder = NULL) : object|boolean
Database Loader
| mixed | $params | Database configuration options |
| boolean | $return | Whether to return the database object |
| boolean | $query_builder | Whether to enable Query Builder (overrides the configuration setting) |
Database object if $return is set to TRUE, FALSE on failure, CI_Loader instance in any other case
view(string $view, array $vars = array(), boolean $return = FALSE) : object|string
View Loader
Loads "view" files.
| string | $view | View name |
| array | $vars | An associative array of data to be extracted for use in the view |
| boolean | $return | Whether to return the view output or leave it to the Output class |
vars(array|object|string $vars, string $val = '') : object
Set Variables
Once variables are set they become available within the controller class and its "view" files.
| array|object|string | $vars | An associative array or object containing values to be set, or a value's name if string |
| string | $val | Value to set, only used if $vars is a string |
clear_vars() : \CI_Loader
Clear Cached Variables
Clears the cached variables.
config(string $file, boolean $use_sections = FALSE, boolean $fail_gracefully = FALSE) : boolean
Config Loader
Loads a config file (an alias for CI_Config::load()).
| string | $file | Configuration file name |
| boolean | $use_sections | Whether configuration values should be loaded into their own section |
| boolean | $fail_gracefully | Whether to just return FALSE or display an error message |
TRUE if the file was loaded correctly or FALSE on failure
driver(string|array<mixed,string> $library, array $params = NULL, string $object_name = NULL) : object|boolean
Driver Loader
Loads a driver library.
| string|array<mixed,string> | $library | Driver name(s) |
| array | $params | Optional parameters to pass to the driver |
| string | $object_name | An optional object name to assign to |
Object or FALSE on failure if $library is a string and $object_name is set. CI_Loader instance otherwise.
remove_package_path(string $path = '') : object
Remove Package Path
Remove a path from the library, model, helper and/or config path arrays if it exists. If no path is provided, the most recently added path will be removed removed.
| string | $path | Path to remove |
_ci_load_stock_library(string $library_name, string $file_path, mixed $params, string $object_name) : void
Internal CI Stock Library Loader
| string | $library_name | Library name to load |
| string | $file_path | Path to the library filename, relative to libraries/ |
| mixed | $params | Optional parameters to pass to the class constructor |
| string | $object_name | Optional object name to assign to |
_ci_init_library(string $class, string $prefix, array|null|boolean $config = FALSE, string $object_name = NULL) : void
Internal CI Library Instantiator
| string | $class | Class name |
| string | $prefix | Class name prefix |
| array|null|boolean | $config | Optional configuration to pass to the class constructor: FALSE to skip; NULL to search in config paths; array containing configuration data |
| string | $object_name | Optional object name to assign to |
