Custom snippet

You can use your own snippet instead of FormIt to do whatever you need (e.g. create pages). The only requirement is that it must return a JSON object with these keys:

Property	Description
status	1 or 0 (success or error)
message	Message about the snippet result; shown when status = 0
data	Object mapping field names to error messages for invalid fields

For convenience, the snippet receives a $FetchIt parameter with the component class so you can call its error and success methods when returning a response.

Minimal custom snippet example:

<?php
if (empty($_POST['name'])) {
  return $FetchIt->error('Form errors', [
    'name' => 'Please enter your name'
  ]);
}
else {
  return $FetchIt->success('Validation passed');
}

Call it like this:

modx

[[!FetchIt?
  &snippet=`MySnippet`
  &form=`tpl.FetchIt.example`
]]

fenom

{'!FetchIt' | snippet: [
  'snippet' => 'MySnippet',
  'form' => 'tpl.FetchIt.example',
]}

This snippet only validates the name field and returns the result.
