$page->meta() method

Get or set page’s persistent meta data

This meta data is managed in the DB. Setting a value immediately saves it in the DB, while getting a value immediately loads it from the DB. As a result, this data is independent of the usual Page load and save operations. This is primarily for internal core use, but may be useful for other specific non-core purposes as well.

Note that this meta data is completely free-form and has no connection to ProcessWire fields. Values for meta data must be basic PHP types, whether arrays, strings, numbers, etc. Please do not use objects for meta values at this time.

Available since version 3.0.133.

Example

// set and save a meta value 
$page->meta()->set('colors', [ 'red, 'green', 'blue' ]);

// get a meta value
$colors = $page->meta()->get('colors');

// alternate shorter syntax for either of the above
$page->meta('colors', [ 'red', 'green', 'blue' ]); // set
$colors = $page->meta('colors'); // get

// delete a meta value
$page->meta()->remove('colors');

// get the WireDataDB instance that stores the meta values,
// it has all the same methods as WireData objects...
$meta = $page->meta();

// ...such as, get all values in an array:
$values = $meta->getArray();

Usage

// basic usage
$wireDataDB = $page->meta();

// usage with all arguments
$wireDataDB = $page->meta($key = '', $value = null);

Arguments

NameType(s)Description
key (optional)string, bool

Omit to get the WireData instance or specify property name to get or set.

value (optional)null, mixed

Value to set for given $key or omit if getting a value.
