Selectors::getSelectorByFieldValue()

Get the first selector that uses given field name AND has the given value

Using $or: By default this excludes selectors that have fields or values 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.

Available since version 3.0.142.

Usage

// basic usage
$selector = $selectors->getSelectorByFieldValue(string $fieldName, $value);

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