Getting a page attribute
In addition to being able to set page attributes, developers can also retrieve attributes just as easily. In this exercise, we will get the Meta Title attribute for the About page.
Getting ready
We are assuming the presence of a page with the path of /about in this recipe. If that page does not exist, you can create it, or adapt the code in this recipe to fit your circumstances.
How to do it...
The steps for getting a page attribute are as follows:
- Open
/config/site_post.phpin your preferred editor. This is a good place to run some arbitrary code. - Load the
Pageobject.$page = Page::getByPath('/about'); - Get the
meta_titleattribute.$title = $page->getAttribute('meta_title'); - Dump the variable using the custom debugging function that we created in the chapter's introduction.
my_debug($title);
How it works...
concrete5 uses the attribute handle string to find the appropriate record in the database and return its value. concrete5 stores attributes in the EAV format (entity, attribute, value), and this makes it difficult to read these values directly with SQL queries. The concrete5 API simplifies this for developers.
