CakePHP Automagic 表单助手与关联
我有两个 CakePHP 模型，测试和问题，其中一个测试有很多问题，而一个问题只有一个测试。
此代码：
echo $form->create("Question", array('action' => 'add'));
echo $form->input("text");
echo $form->input("Test.id", array( 'value' => $test['Test']['id'] , 'type' => 'hidden') );
echo $form->end("Add");
Nor:
echo $form->create("Question", array('action' => 'add'));
echo $form->input("text");
echo $form->input("Question.Test.id", array( 'value' => $test['Test']['id'] , 'type' => 'hidden') );
echo $form->end("Add");
都不将新问题与测试相关联（但确实在数据库中创建它）。
$test['Test']['id'] 确实会产生正确的 ID 输出。
感谢您的帮助。
I have two CakePHP models, Tests and Questions, where a Test has many questions, and a Question only has one test.
Neither this code:
echo $form->create("Question", array('action' => 'add'));
echo $form->input("text");
echo $form->input("Test.id", array( 'value' => $test['Test']['id'] , 'type' => 'hidden') );
echo $form->end("Add");
Nor:
echo $form->create("Question", array('action' => 'add'));
echo $form->input("text");
echo $form->input("Question.Test.id", array( 'value' => $test['Test']['id'] , 'type' => 'hidden') );
echo $form->end("Add");
associates the new question with a test (but does create it in the database).
$test['Test']['id'] does produce a correct output of ID.
Assistance appreciated.

您应该将两个模型与
hasOne和hasMany关联关联（如果您尚未这样做），并在表中创建questions名为test_id的列（名为 foreignKey）。那么问题的形式就变成了：
You should associate (if you haven't done it yet) the two models with
hasOneandhasManyassociations and doing so creating in the tablequestionsa column calledtest_id(that's named foreignKey).The form of the question then becomes:
你的命名已关闭。您应该改为调用隐藏字段 Question.test_id ，因为这是应保存值的字段。例如：
Your naming is off. You should call your hidden field Question.test_id instead, since that is the field where the value should be saved. For example:
我知道这个问题已经很老了，但是对于那些像我一样来这里寻找 CakePHP 3 答案的人来说，输入的关联命名约定已经改变，用
table.field表示 BelongsTo/HasOne 关联，>tables.field用于 HasMany/BelongsToMany 关联。阅读文档 了解更多信息。
I know that this question is old, but for those who came here like me looking for CakePHP 3 answers, the association naming convention for inputs has changed, with
table.fieldfor BelongsTo/HasOne associations andtables.fieldfor HasMany/BelongsToMany associations.Read the docs for more info.
