[FIXED] How to pass value of parent id in child controller in cakephp3

Issue

I have just started learning cakephp3, so please excuse me for anything wrong. So I have one table called Projects and Events, so there relation is like one project can have many events.

When the user is adding a new project, he will be redirected to 'add' event in Controller 'events '.

testapp/projects/add --> testapp/events/add

The code in default add.ctp has a dropdown of projects but i want it to be the normal text field with the value of just created project instead of dropdown.

Please tell how can I achieve this?

Thanks in advance

Solution

somewhere in your ProjectsController you shoud have something like

redirect(['action' => 'add', 'controller' => 'Events'])

and you should have a variable named $project storing a ProjectEntity

just pass the project id to the redirect action

redirect(['action' => 'add', 'controller' => 'Events', $project->id])

then in your EventsController you'll read the value and store it to the Event entity this way

function add($project_id)
{
    // Do something
    $event = $this->Events->newEntity();
    $event->project_id = $project_id; 
    // do something else
}
