Php变量在Cakephp模型 [英] Php Variable in Cakephp Model

问题描述

我试图使用join与两个表通过使用有很多关系的CakePHP与条件我的模型代码在这里使用

i am trying to use join with two table by using has many relation of CakePHP with condition my model code are here which am using

public $userid = 3;
    public $name = 'Course';
    public $hasMany = array(
        'Enrollcourse' => array(
            'className'     => 'Enrollcourse',
            'foreignKey'    => 'course_id',
            'conditions'    => array('Enrollcourse.student_id' => $this->userid),
            'dependent'     => true
        )
    );

或

   public $userid = 3;
        public $name = 'Course';
        public $hasMany = array(
            'Enrollcourse' => array(
                'className'     => 'Enrollcourse',
                'foreignKey'    => 'course_id',
                'conditions'    => array('Enrollcourse.student_id' => $userid),
                'dependent'     => true
            )
        );

这里是$ userid是变量，用于检查选定用户的数据，但无法得到这个&发生以下情况

here is $userid is Variable which are use as checking to reterive data of selected user but am unable to get this & following are occur

Error: parse error
File: E:\wamp\www\simpleApp\app\Model\course.php
Line: 10

任何帮助

推荐答案

您不能在类中声明变量时使用变量。这意味着使用 $ userid 将导致您看到的解析错误。

You cannot use variables in the declaration of a variable within a class. This means that use of $userid will cause the parse error you are seeing.

克服这个问题的最好方法动态信息是替换/重载模型的构造函数：

The best way to overcome this for dynamic information is to replace/overload the constructor for the model:

public function __construct($id = false, $table = null, $ds = null) {
    $this->hasMany = array(
        'Enrollcourse' => array(
            'className'     => 'Enrollcourse',
            'foreignKey'    => 'course_id',
            'conditions'    => array('Enrollcourse.student_id' => $this->userid),
            'dependent'     => true
        )
    );
    parent::__construct($id, $table, $ds);
}

这就克服了类变量声明中变量的使用。

This overcomes the use of a variable during a class variable declaration.
