I am trying to load a model in a library.
This is how I am loading it,
class Init{
private $CI;
function __construct()
{
$this->CI = &get_instance();
$this->CI->load->model("backend/StoreSettings_Model");
}
}
When I try to access the method in the storesettings_model, I get the following error Undefined property: Init::$Storesettings_Model
public function settingsSetUp($store_name){
$settings = $this->CI->storesettings_model->getStoreSettings($store_name);
}
I have tried the changing the case to match the case of the class I am loading to StoreSettings_Model... still same problem
If I load the library with all lower case then it will work, but then when I upload to my development server which runs on Linux, it will throw an error because the class name is StoreSettings_Model and the im instantiating with storesettings_model
Has anyone face this issue before? If so what do you suggest about fixing it?
Any help would be really appreciated.
Try this
function __construct()
{
# $this->CI = &get_instance(); < ---- remove this
$this->load->model("backend/StoreSettings_Model"); # remove CI->
}
in Method
public function settingsSetUp($store_name){
$settings = $this->storesettings_model->getStoreSettings($store_name); # remove CI-> on here too
}

I am new in flight php.
I need some help, I create two classes client.class.php and deliveryServiceConnector.class.php and i have index.php. I want to use function from deliveryServiceConnector.class.php in client.class.php so I write this code:
public function __construct() {
$this->connector = new deliveryServiceConnector(DOLIBARR_API_KEY,DOLIBARR_ROOT_URL,NuLL, $this->nodeName);
$connector->testDisplayDev();
}
I got this error:
Undefined variable: connector (8)
Any idea how can i fix my error, Thanks
You're not using the same thing for the deliveryServiceConnector. In the first line, inside the function, you use $this->connector, but in the second line you use $connector. Therefore it is undefined. Try to use the same thing twice. Either:
public function __construct() {
$this->connector = new deliveryServiceConnector(DOLIBARR_API_KEY,DOLIBARR_ROOT_URL,NuLL, $this->nodeName);
$this->connector->testDisplayDev();
}
or
public function __construct() {
$connector = new deliveryServiceConnector(DOLIBARR_API_KEY,DOLIBARR_ROOT_URL,NuLL, $this->nodeName);
$connector->testDisplayDev();
}
I am calling function form library in codeigniter and it's giving me below error
PHP Fatal error: Cannot access property started with '\0' in /system/core/Exceptions.php on line 85
Code:
$this->load->library('test_library');
TEST_LIBRARY::first();
Class file:
class TEST_LIBRARY
{
public function first(){
return "here";
}
}
However, when I call the function using this method $this->test_library->first(); it's working fine.
It was working both ways before not sure what's going on. There is no other log messages in error.log file. How can I debug further and fix this issue?
Function first is not static but you called as if it is. Change test_libaray.php to :
class TEST_LIBRARY {
public function __construct() {}
public function first() {
return "here"; // i suggest to use __METHOD__ or __LINE__ instead
}
}
And then try:
$test_library = new TEST_LIBRARY();
$test_libaray->first();
instead of:
TEST_LIBRARY::first();
Or you can just change first static.
I created a custom Library in CodeIgniter, and positioned it in application/libraries/VarMatrixSpecanimal.php
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class VarMatrixSpecanimal {
protected $variabiliMatrix;
public function __construct() {
$variabiliMatrix['cat']['no']=1;
$variabiliMatrix['dog']['a']=2;
$variabiliMatrix['bird']['b']=3;
}
public function get_matrix() {
return $this->variabiliMatrix;
}
}
?>
Then in one controller (application/controllers/certificate.php) method I added these two lines of code:
public function save1()
{
//..... some more code before
$this->load->library('VarMatrixSpecanimal');
$numerical_values = $this->varmatrixspecanimal->get_matrix();
//..... some more code after
But when I call save1 method, I get this error:
A PHP Error was encountered
Severity: Notice
Message: Undefined property: Certificate::$varmatrixspecanimal
Filename: controllers/certificate.php
Line Number: 139
I don't understand where I do wrong, please help me.
I checked also CodeIgniter help http://www.codeigniter.com/user_guide/general/creating_libraries.html but I was not able to get my error
Add get_instance() function in constructor in VarMatrixSpecanimal.php
public function __construct()
{
$this->variabiliMatrix =& get_instance();
}
After this load library on your controller
$this->load->library('varmatrixspecanimal');
I have experienced anything like this because I forgot this line of code:
parent::__construct
in my __construct or constructor.
Add include file with correct path at the top of program will solve this issue.
include "../../VarMatrixSpecanimal.php";
Try to change your constructor from this:
public function __construct() {
$variabiliMatrix['cat']['no']=1;
$variabiliMatrix['dog']['a']=2;
$variabiliMatrix['bird']['b']=3;
}
to this:
public function __construct() {
$this->variabiliMatrix['cat']['no']=1;
$this->variabiliMatrix['dog']['a']=2;
$this->variabiliMatrix['bird']['b']=3;
}
Also, when loading your library i think you don't need to uppercase any letters
For my current project i decided to create a library for some common functionalities.
Ex : Login_check,get_current_user etc.
With my little knowledge i created a simple one but unfortunately its not working.
Here my library :
FileName : Pro.php and located in application/libraries
class Pro{
public function __construct()
{
parent::_construct();
$CI =& get_instance();
$CI->load->helper('url');
$CI->load->library('session');
$CI->load->database();
}
function show_hello_world()
{
$text = "Hello World";
return $text;
}
}
?>
And i tried to load it on my controller :
<?php
class Admin extends CI_Controller
{
function __construct()
{
parent::__construct();
$this->load->database();
$this->load->library(array('session'));
$this->load->library("Pro");
}
function index()
{
echo($this->Pro->show_hello_world());
}
}
?>
I cant see any erros there...but i am getting a blank page.
Whats wrong with me ??
Thank you .
Edit : I got this error :
Call to a member function show_hello_world() on a non-object in C:\wamp\www\Project\application\controllers\admin.php on line 13
One thing I notice: remove the parent::__construct() from your library constructor, because it's not extending anything so has no parent to call.
Also, enable error reporting by setting the environment to "development" in index.php, and you might also want to raise the logging threshold to 4 in config/config.php so you log errors.
Try this simple test-case:
file Pro.php in application/libraries:
class Pro {
function show_hello_world()
{
return 'Hello World';
}
}
Controller admin.php in application/controllers
class Admin extends CI_Controller
{
function index()
{
$this->load->library('pro');
echo $this->pro->show_hello_world();
}
}
while your class name is capitalized, all your references to the library when loading it and using it should be lower case. you also do not need the constructor, as the other commenter mentioned.
so instead of:
echo($this->Pro->show_hello_world());
you should have:
echo($this->pro->show_hello_world());
I prefer the standard php autoloader approach, with this you dont need to change your classes at all, you can use your standard classes without modifications
say for instance you class is class 'Custom_Example_Example2' and is stored in libraries
in sub folders you can add this autoloader in the master index.php
make sure it is added below the defined APPPATH constant
//autoload custom classes
function __autoload($className) {
if (strlen(strstr($className, 'Custom_')) > 0 ||
strlen(strstr($className, 'Other1_')) > 0 ||
strlen(strstr($className, 'Other2_')) > 0) {
$exp = explode('_', $className);
$file = APPPATH.'libraries';
if(!empty($exp)) {
foreach($exp as $segment) {
$file .= '/'.strtolower($segment);
}
}
$file .= '.php';
require_once $file;
//debug
//echo $file.'<br />';
}
}
This will look for class calls matching the 'Custom_' prefix
and reroute them to the relative location in this case
you only need to define the base prefix not the sub folders / classes
these will be auto detected by this code
APPPATH.'libraries/custom/example/example2.php'
You can call it in the controller the standard php way
$class = new Custom_Example_Example2;
or
$class = new custom_example_example2();
You can modify the script to your liking currently it expects all folders and filenames in the library to be lowercase but you can remove the strtolower() function to allow multiple casing.
you can change the require once to echo to test the output by uncommenting this line and refresh the page, make sure you have a class init / test in the controller or model to run the test
echo $file.'<br />';
Thanks

In Pro.php
class Pro{
protected $CI;
public function __construct() {
$this->CI = & get_instance();
}
public function showHelloWorld(){
return "Hello World";
}
}
In your controller
class Staff extends CI_Controller {
public function __construct() {
parent::__construct();
$this->load->database();
$this->load->helper(array('url_helper', 'url'));
$this->load->library("pro");
}
public function index() {
echo $this->pro->showHelloWorld();die;
}
}
Just do these things you can access your custom library in codeignitor.
I have a problem, everything was working but then I tried to put my functions in my own libraries (to use them in different controllers) and it doesn't work.
I have SIGNUP controller with this:
$this->load->library('Check_functions');
// We check the form
$return_verif_form_signup = $this->check_functions->verif_form_signup($language);
which calls my librarie Check_functions:
class Check_functions {
public function verif_form_signup($language) {
if ($this->input->post()){
// Verification rules
$this->form_validation->set_rules('name', 'lang:name', 'trim|required|xss_clean');
....
if ($this->form_validation->run($this)) {
extract($_POST);
...
...
}
But I get the error:
Fatal error: Call to a member function post() on a non-object
Does anyone know how I could fix it?
thanks!
EDIT:
I have found the problem, the callback function is not called. If I replace callback_free_email by REQUIRED and I don't enter an email, my form is not submitted, so it's okay.
But if I have the following code, my form is always submitted. So the callback function is never called...
This is my code (i'm using HMVC):
class Check_functions {
private $CI;
public function __construct(){
$this->CI =& get_instance();
}
public function verif_form_signup($language) {
if ($this->CI->input->post()){
$this->CI->form_validation->set_rules('name', 'lang:field_name', 'trim|required|min_length[3]|max_length[25]|xss_clean');
$this->CI->form_validation->set_rules('email_signup', 'lang:field_email', 'callback_free_email');
...//other rules
if ($this->CI->form_validation->run($this->CI)) {
.....
}
}
}
public function free_email($str) {
return FALSE; // I have temporarly set that so I see if my function is called
}
}
I have a file called MY_Form_validation.php as suggested here: http://codeigniter.com/forums/viewthread/143057/#769347
class MY_Form_validation extends CI_Form_validation{
function run($module = '', $group = ''){
(is_object($module)) AND $this->CI = &$module;
return parent::run($group);
}
}
I really don't know what's wrong... why my callback function is not called?
Thank you for your help!
when you are writing libraries, you have to manually grab the Codeigniter instance like this
$CI =& get_instance();
then you would use $CI where you would normally use $this to interact with loaded codeigniter resources
so...
instead of
$this->input->post();
you would write
$CI->input->post();
Docs explain it here http://codeigniter.com/user_guide/general/creating_libraries.html
EXAMPLE LIBRARY STRUCTURE
class Examplelib {
// declare your CI instance class-wide private
private $CI;
public function __construct()
{
// get the CI instance and store it class wide
$this->CI =& get_instance();
}
public function lib_function()
{
// use it here
$this->CI->db->etc()
}
public function another_func()
{
// and here
$this->CI->input->post();
}
}
I finally found a workaround, instead of using the callback in my rule, I do a test later and call a verification function.
It’s works well like that.
Thanks for your help!
