Is it possible to change the Notes of a field with a Hook?

Is it possible to change the Notes of a field with a Hook? The field belongs to a PageTable.

[bernhard]

yes

Spoiler

// site/ready.php
$wire->addHookBefore('Inputfield::render', function(HookEvent $event) {
  $field = $event->object;
  if($field->name != 'yourfield') return;
  $field->entityEncodeText = false;
  $field->notes = 'this is <strong>UNTESTED</strong>';
});

The other option is: http://modules.processwire.com/modules/dynamic-description-notes/

It works great. Thank you.

I hope you can help me with 1 more thing: The field belongs to a PageTable. That PageTable is used under 2 different templates: template1 & template2. I want to change the field notes ONLY for template2.

I figured how to do it:

$wire->addHookBefore('Inputfield::render', function(HookEvent $event) {
	
	$field = $event->object;
	if($field->name != 'myfield') return;
	$page = $this->process->getPage();
	$parent = $page->parent();
	if ($parent->template->name == "mytemplate") {
	$field->entityEncodeText = false;
	$field->notes = 'My new notes!';
	}
	
});

Please correct me if I did something wrong.

How can I do the same thing on a field that belongs to a repeater???

[bernhard]

ok didn't know there is a difference.

if you do not do already i recommend using adrians awesome tracy debugger module. then you see that inside a repeader the field has a different name:

$wire->addHookBefore('Inputfield::render', function(HookEvent $event) {	
	$field = $event->object;
	bd($field->name);
});

hope that helps and you find your solution on your own  i'm busy

Easiest way that works for inputfields both inside and outside of repeaters is to match the name of the field associated with the inputfield:

$wire->addHookBefore('Inputfield::render', function(HookEvent $event) {
    $inputfield = $event->object;
    if($inputfield->hasField == 'YOUR_FIELD_NAME') {
        //...

Here is the solution:

$wire->addHookBefore('Inputfield::render', function(HookEvent $event) {
	
	$field = $event->object;
	$page = $this->process->getPage();
	
	if($field->hasField == 'myfield' && $page->template->name == "mytemplate") {
		$field->entityEncodeText = false;
		$field->notes = 'My new notes!';
	}
	
});

Thanks for your tips.

Now I cannot access Setup > Templates. I'm getting this error: ProcessWire: ProcessTemplate: Method ProcessTemplate::getPage does not exist or is not callable in this context.

BTW, it would be better to hook a more specific inputfield render rather than just Inputfield::render. So something like InputfieldPageTable::render or whatever inputfield type you are targeting.

I replaced Inputfield::render with InputfieldRepeater::render but it doesn't work.

you need to use the classname of the inputfield that you are modifying. your field is inside a repeater, but it is not a repeater itself. if it is a textfield you have to use InputfieldText, if it was a checkbox it would have to be InputfieldCheckbox.

Also $field->entityEncodeText = false; is only necessary if you want to use markup in your note
