Have a differeent title on a field across multiple templates?

[OpenBayou]

Hello,

This is minor question not really important. I have a field called 'item description' that I use on multiple templates. Is there a way to have a different title on that field depending on the template? Example: on template a, have the field title called Description and on template b, have the field called Example? Or is it easier to have a different field on different templates?

 

Thanks

It's an old video, but shows you about template context field settings: https://processwire.com/videos/field-template-context/

...and that is just the tip of the iceberg

just an example: put this inside your /site/ready.php

$this->addHookAfter('ProcessPageEdit::buildForm', function($event) {
    $form = $event->arguments(0);
    $field = $form->get('yourfieldname');
    $page = $event->object->getPage();

    if($page->template == 'template_a') $field->label = "this is field label on template a, it is " . date("d.m.Y H:i:s");
    elseif($page->template == 'template_b') $field->label = "this is field label on template b, it is " . date("d.m.Y H:i:s");
    else $field->label = "other template, it is " . date("d.m.Y H:i:s");
});

have fun with processwire

Still don't get used to the hooks. Any useful links? I do still prefer  the (maybe hard) way with just no hooks...

it may seem complicated in the beginning, but once you get the concept it's really easy and straightforward. you just have to look a bit into the code to know what is going on behind the scenes. take my code example, it's easy:

// attach a hook whenever a page edit form is built
// this happens in the class "ProcessPageEdit" in method "buildform"
// see github how this method looks like: https://github.com/processwire/processwire/blob/master/wire/modules/Process/ProcessPageEdit/ProcessPageEdit.module#L588-L595
$this->addHookAfter('ProcessPageEdit::buildForm', function($event) {
	// $event is the hookevent object; it holds all necessary data to execute all kinds of actions
	// https://github.com/processwire/processwire/blob/master/wire/modules/Process/ProcessPageEdit/ProcessPageEdit.module#L591
	// here you see that the method gets 1 parameter and this parameter is the form, so if you want to get this form just do this:
    $form = $event->arguments(0);

	// to get the field of your form just do the following
	// see https://github.com/processwire/processwire/blob/master/wire/modules/Inputfield/InputfieldForm.module
	// or https://processwire.com/talk/topic/2089-create-simple-forms-using-api/
    $field = $form->get('yourfieldname');

	// now we want to do something based on the page that is edited
	// that is a bit different than in template context because we are VIEWING an admin page, whereas we are EDITING a different page
	// we want to know the template of the EDITED page, so let's get it...
	// $event->object is the class where the hook is attached. in our case "ProcessPageEdit"
	// to get the edited page this class has an own method: https://github.com/processwire/processwire/blob/master/wire/modules/Process/ProcessPageEdit/ProcessPageEdit.module#L2009-L2019
    $page = $event->object->getPage();

    if($page->template == 'template_a') $field->label = "this is field label on template a, it is " . date("d.m.Y H:i:s");
    elseif($page->template == 'template_b') $field->label = "this is field label on template b, it is " . date("d.m.Y H:i:s");
    else $field->label = "other template, it is " . date("d.m.Y H:i:s");
});

always depends what you want to do. only changing the field label on different templates would perfectly be fine without a hook. adding date+time would not be possible without a hook

i just wanted to give a simple example what could be the next step

Nice example! Will soon dive deeper into this. In any case, a big thank you!
