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.

    You should associate (if you haven’t done it yet) the two models with hasOne and hasMany associations and doing so creating in the table questions a column called test_id (that’s named foreignKey).

    The form of the question then becomes:

    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");
