这是我的图书馆：

defined('BASEPATH') OR exit('No direct script access allowed');

class AlertClasse
{
    protected $CI;

    public function __construct()
    {
        $this->CI =& get_instance();
        $this->CI->load->model('AlerteModel');

    }

    public function stockSeuil()
    {
        $query=$this->CI->AlerteModel->getarticles();
        $tabStockSeuil = array();
        foreach($query as $tab)
        {

            if($tab->art_solde<=$tab->seuil_alert_art)
            {
              $article[] = $tab->id_art;
              $article[] = $tab->lib_art;
              $article[] = $tab->art_solde;
              $article[] = $tab->seuil_alert_art;   
              $article[] = $tab->perissable;        
              $tabStockSeuil[] = $article;
              $article = array();
            }
        }
        return $tabStockSeuil;
    }

    public function stockExpire()
    {
        $query=$this->CI->AlerteModel->get_art_lot();
        $tabartexpire = array();
        $datejour = date('d/m/Y');

         $djour = explode("/", $datejour);

        $auj = mktime(00, 00, 00,$djour["1"],$djour["0"],$djour["2"]);


        foreach($query as $tab)
        {

            if($tab->date_expir!=0)
            {

            $datexpiration= $tab->date_expir;  

            if ($auj>=$datexpiration)
            { 
                $id = $tab->id_lot;
                $artexpire[] = $tab->lib_art;
                $artexpire[] = $tab->qte_lot;
                $artexpire[] = $tab->date_enregistrement;
                $artexpire[] = $tab->date_expir;

                $tabartexpire[] =$artexpire;
                $this->articles_model->mis_au_rebut($id);
                $artexpire = array();

            }
        }

            }
          return $tabartexpire;
    } 


    public function ExpireProche()
    {
        $query=$this->CI->AlerteModel->get_art_lot();
        $tabartexpire = array();
        $datejour = date('d/m/Y');

         $djour = explode("/", $datejour);

        $auj =  mktime(00, 00, 00, $djour["1"], $djour["0"], $djour["2"]);

        $nextDat =time() + (5 * 24 * 60 * 60);
        $temp =date('d/m/Y', $nextDat);
        $temp = explode("/", $temp);  

        $nextDate  = mktime(00, 00, 00, $temp["1"],$temp["0"],$temp["2"]);    
        foreach($query as $tab)
        {
            if($tab->date_expir!=0)
            {

            $datexpiration= $tab->date_expir; 



          if (intval($auj)<intval($datexpiration) && intval($nextDate) >= 
        intval($datexpiration))
            { 

                $artexpire[] = $tab->lib_art;
                $artexpire[] = $tab->qte_lot;
                $artexpire[] = $tab->date_enregistrement;
                $artexpire[] = $tab->date_expir;
                // On met ensuite le résultat obtenu dans un tableau 
                $tabartexpire[] =$artexpire;
                $artexpire = array();

         }
        }


            }

            return $tabartexpire;


    }
}

并在我的控制器中：

defined('BASEPATH') OR exit('No direct script access allowed');

class ControllerUser extends CI_Controller {

    function __construct() {

        parent::__construct();
        $this->load->library('alertClasse');
        $this->load->database();
        $this->load->library('session');
    }
}

这里我尝试访问该方法：

public function affichageUser(){
   //error here
    $tabExpirProch = $this->alertClasse->ExpireProche();
    $priv = $this->UserModel->getpriv();
    $this->load->view('users/listUser',['privilege'=>$priv]);
}

Answer 1

发生此错误是因为codeigniter无法在您的应用程序/库文件夹中找到该文件。

确保您图书馆课程的文件名为“AlertClasse.php” 因为codeigniter声明了以下创建库的规则：

文件名必须大写。例如：Myclass.php

类声明必须大写。例如：class Myclass

班级名称和文件名必须匹配。

https://www.codeigniter.com/userguide3/general/creating_libraries.html#storage

Answer 2

您必须使用类的名称访问库的方法：

$tabExpirProch = $this->AlertClasse->ExpireProche();

Answer 3

我的proyect也有同样的问题。我可以通过这种方式调用每个模型，在CI v3.1.6上

模型（仅显示差异）：

class SomeClass extends CI_Model{
    function __construct(){
        parent::__construct()
    }
    function someFunction($foo){
        //do something
    }
}

在控制器中：

class SomeController extends CI_Controller{
    function __construct(){
        parent::__construct();
        //Load model, no problem
        $this->load->model('SomeClass');
        //Load library, no problem
        $this->load->library('MyLibrary');
    }
    function someFunctionToUseModelFunction(){
        $foo = 'Hello my friend';
        //no problem with using the model
        $bar = $this->SomeClass->SomeFunction($foo);
        //library, NOT FOUND
        $a = $this->MyLibrary->someFunctionInLibrary();
    }
}

当我尝试使用库时，当我无法调用库中的函数时，我无法检查名称，文件名，我在哪里调用那些......没有。（抱歉我的英文）我“小写”了图书馆的名字，我做了这个

function __construct(){
    $this->load->library('MyLibrary');
}

function functionToCallTheLbrary(){
    //this way it has worked for my so far with all the libraries i have
    //lowercase the class name, and call the functions with the names u declare those
    $var = $this->mylibrary->someFunction();
}

希望我的回答能帮到你。
