Setting the Auto Parent-Child Relation to Posts Via a Front End Form (Legacy)

Create a form for Child posts and display it on a Single template for Parent posts. It will have a required One to Many relation if you insert the relation meta key in the right field of the Form.

Before you start, check the tutorial requirements:

  • Elementor (Free version) or Block editor (Gutenberg)

  • JetEngine plugin installed and activated

    with the Relations (Legacy) configured and the Forms (Legacy) module enabled.

Create a Post Types Relation

Make sure that you do have the necessary post types to be interrelated. If not, create them. We’ll be referring to these two: Country & Tour. To create a relation, go to JetEngine > Relations and set the One to Many relation as shown below:

Create a Test Form

Go to JetEngine > Forms > Add New and create a form that allows adding a new post from the frontend:

Display the Form on the Front-end

Open the Tour CPT and find the necessary post in the WordPress dashboard.

If it doesn’t exist, you need to create it either in the Elementor theme builder or in the Crocoblock theme builder:

edit tour single page

Display the newly-created test form:

Fill in the Form

On the front-end, try filling out the added form and press the “Add new post” button:
