Selectors::getSelectorByField() method

Get the first selector that uses given field name

This is useful for quickly retrieving values of reserved properties like "include", "limit", "start", etc.

Using $or: By default this excludes selectors that have fields in an OR expression, like "a|b|c". So if you specified field "a" it would not be matched. If you wanted it to still match, specify true for the $or argument.

Using $all: By default only the first matching selector is returned. If you want it to return all matching selectors in an array, then specify true for the $all argument. This changes the return value to always be an array of Selector objects, or a blank array if no match.

Usage

// basic usage
$selector = $selectors->getSelectorByField(string $fieldName);

// usage with all arguments
$selector = $selectors->getSelectorByField(string $fieldName, bool $or = false, bool $all = false);

Arguments

NameType(s)Description
fieldNamestring

Name of field to return value for (i.e. "include", "limit", etc.)

or (optional)bool

Allow fields that appear in OR expressions? (default=false)

all (optional)bool

Return an array of all matching Selector objects? (default=false)

Return value

Selector array null

Returns null if field not present in selectors (or blank array if $all mode)

“To Drupal, or to ProcessWire? The million dollar choice. We decided to make an early switch to PW. And in retrospect, ProcessWire was probably the best decision we made. Thanks are due to ProcessWire and the amazing system and set of modules that are in place.” —Unni Krishnan, Founder of PigtailPundits
