How to add variables in a form textarea

Question

I would like to create custom confirmation messages that could be easily updated by the admins.

Like

 <textarea>You can contact {contact_name} located at {contact_place}…</textarea>

contact_name and contact_place are fields that will be completed in the same form, and are both required.

Is it something easy to manage?

don's think you would be able to achieve this with PHP. If understood correctly, you would like to fill contact_name and contact_place on the fly once the corresponding fields are filled in the form. Is that right? — Yevgeniy, Oct 07 '21 at 07:29
Not exactly. For example, in my view(), I would like to identify {contact_name} and {contact_place} and replace them dynamically with the appropriate fields, for example event->name and event->place. — , Oct 07 '21 at 10:44
if you have data in a variable at the time of generating the form you could stick it in HTML like so: `You can contact = $event->name?> located at = $event->place ?>`. Or do you generate your form using `= $this->Form->control('textarea_field_name') ?>`? — Yevgeniy, Oct 07 '21 at 11:24

Save the text string with placeholders in db, then use str_replace in custom Helper or in entity virtual fields

   return str_replace(
      [
         '{{contact_name}}', // placeholders
         '{{contact_place}}', 
         '{{email}}',
      ],
      [
         $contact->name, // inputs
         $contact->place,
         $contact->email,
      ],
       // load template string from db
      // You can contact {{contact_name}} located at {{contact_place}}…
      $admin->template
   );
