cakephp2无法显示包含

我正在使用cake php 2开发一个网络应用程序。

我在显示2个表中的数据时遇到问题......

我的模特:

<?php 

    class Discipline extends AppModel{

        public $hasMany = "Student";
    }

?>

<?php 

    class Student extends AppModel{

        public $belongsTo = array(
            "Discipline" => array(
                "className" => "Discipline",
                "foreignKey" => "discipline_id"
            )      
        );

    }

?>

这是我的学生控制器:

<?php
class StudentsController extends AppController{

    function admin_index(){
        if($this->request->is('put') || $this->request->is('post')){
            $student = $this->request->data['Student'];
            if($this->Student->save($this->request->data)){
                $this->Session->setFlash("L'eleve a bien été modifié","notif");
            } 
        }
        $d['student'] = $this->Student->find('all',array(
            'contain' => "Discipline"
        )); 
        $this->set($d);
    }
}

我正在尝试使用此视图显示学生的数据:

<?php

foreach($student as $k => $v){ 
    $v = current($v);

    echo "<td>Action</td>";
    echo "<td>Label</td>";
    echo "<td>".$v['nom']." ".$v['prenom']."</td>"; 
    echo "<td>".$v['sexe']."</td>"; 
    echo "<td>".$v['naissance']."</td>"; 
    echo "<td>".$v['Discipline']['designation']."</td>"; 
    echo "<td>".$v['comite']."</td>"; 
    echo "<td>".$v['classe']."</td>"; 
    echo "<td>".$v['elite']."</td>"; 
    echo "<td>".$v['alerte']."</td>"; 
    echo "<td>".$v['quota1']."</td>"; 
    echo "<td>".$v['quota2']."</td>"; 
    echo "<td>".$v['total']."</td>"; 
    echo "<td>Pris</td>"; 
    echo "<td>Restant</td>"; 
    echo "<td>Supp</td>"; 


}

?> 

但我在这一行有一个问题:

 echo "<td>".$v['Discipline']['designation']."</td>";

它说错误:

notice (8): Undefined index: designation [APP\View\Students\admin_index.ctp, line 47]

我习惯于在cakephp 3上进行开发,我对这个错误感到非常尴尬......如何从学生视图中显示来自Disciplines表的数据?

有什么想法吗? THX

编辑:我在StudentsController上进行了调试,找到了我想要显示的数据:

array(
    'student' => array(
        (int) 0 => array(
            'Student' => array(
                'id' => '2',
                'prenom' => 'Jean',
                'nom' => 'Michel',
                'sexe' => '1',
                'naissance' => '2015-08-02',
                'age' => '12',
                'classe' => '1',
                'discipline_id' => '1',
                'comite' => 'test',
                'categorie' => 'test',
                'elite' => true,
                'alerte' => 'test',
                'quota1' => '12',
                'quota2' => '12',
                'total' => '24',
                'note' => 'tete'
            ),
            'Discipline' => array(
                **'id' => '1',
                'designation' => 'Alpin'**
            )
        )
    )
)

答案 0 :(得分:0)

我认为你应该改变观点

变化:

foreach($student as $k => $value){ 
    $v = current($value);

为:

foreach($student as $k => $v){ 
    $v = current($v);

并改变:

echo "<td>".$v['Discipline']['designation']."</td>"; 

echo "<td>".$value['Discipline']['designation']."</td>";

你用第一个找到的数组覆盖变量$ v,所以$ v将是$ v ['Student']

我自己不会使用current进入CakePHP的数组,但是到处使用$ v ['Student']
