Page Property
Using page properties.
To call a property from a page, do this:
$page->fooBar;
The default value is always null
. This is the thing that makes Mecha version 2.x.x
different from version 1.x.x
. In version 1.x.x
, calling a property that does not exist from a page will trigger an error message, but not in version 2.x.x
. In version 2.x.x
, any page property is valid and has the value of null
unless you set a value explicitly to it, either from page header, page data, or from a return value generated by hooks.
To set a value to the fooBar
property, add a data in the page header with foo-bar
as the property key:
---
title: Test Page
description: Testing page property.
type: Markdown
foo-bar: Test property value of `fooBar`.
...
Lorem ipsum dolor sit amet.
To set a value to the fooBar
property from a separated file, add a file named as foo-bar.data
to the related folder:
.\
└── lot\
└── page\
├── test-page\
│ └── foo-bar.data
└── test-page.page
To set a value to the fooBar
property with a hook, do this:
Hook::set('page.foo-bar', function ($value) {
// `$value` is `null` by default
return 'Test property value of `fooBar`.';
});
Now, $page->fooBar
will return “Test property value of `fooBar`.”.
