如何在表单文本区域中添加变量

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?

Answer 1

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
   );
