将一个变量传递给Symfony表单 [英] Pass a variable to a Symfony Form
问题描述
我正在使用Symfony 1.4和Doctrine为一所学校构建一个Web应用程序,并且我想制作一个非常简单的表单来为学生添加课程。
我的主要问题是,在下拉列表中,我只想显示学生当前没有注册的课程。我已经在模型中有一个函数(在Student.class.php中),它返回所有没有注册学生的课程,但问题是我不知道如何将学生传递给表单的configure()。我已经尝试了几个选项,比如将它与表单的构造函数一起传递给一个全局变量或一个特殊的set方法,但它们都没有工作。
是否有任何形式将学生传递给configure()方法?
谢谢!

在你的动作中:
$ this-> ; form = new StudentCourseForm(array(),array('student_id'=> $ student_id));
在表单类中:
$ this-> getOption('student_id');
I am building a web application using Symfony 1.4 and Doctrine for a school and I want to make a very simple form to add a course to a student.
The main problem I have is that in the drop down list I only want to show the courses in which the student is currently not enrolled.
I already have a function in the model (in Student.class.php) which returns all the courses in which the student is not enrolled but the problem is I don't know how to pass the student to the configure() of the form. I have tried several options like passing it with the constructor of the form to a global variable or a special set method but none of them have worked.
Is there any form to pass the student to the configure() method?
Thanks!
This should work for you...
In your action:
$this->form = new StudentCourseForm(array(), array('student_id' => $student_id));
In the form class:
$this->getOption('student_id');
