Cakephp 3 multiple custom template formhelpers

Question

So I\'m at work (working with sensitive data might I add for posterity\'s sake), and the powers that be decide we need to use the all powerful and least documented new tool by C

Answer 1

Let's say you need all inputs to use a custom markup in a form to show the label after the input (default is before) and a different class for the hardcoded error-message for errors:

$this->Form->create($entity, ['templates' => [
    'formGroup' => '{{input}}{{label}}',
    'error' => '
{{content}}
'
]]);

If you want to only customize a single input, pass the same 'templates' key to the FormHelper::input() options like so:

$this->Form->input('fieldname', ['templates' => [
    'formGroup' => '{{input}}{{label}}',
    'error' => '
{{content}}
'
]]);

If you need to define multiple templates and re-use them whenever you want, here's something you can try (mind I am writing it here, never used it before):

// in bootstrap (as this is a config i believe
Configure::write('templates', [
    'foo' => [....],
    'bar' => [....]
]);

// in any view
$this->Form->templates(Configure::read('templates.foo'));
$this->Form->create(...);
....

You could also create your own helper and define the templates there, etc.

It really all depends on what you want to achieve but that should give you a good understanding of how templates work (not just in forms by the way).
