$sanitizer->selectorValue() method

Sanitizes a string value that needs to go in a ProcessWire selector

Always use this to sanitize any string values you are inserting in selector strings. This ensures that the value can't be confused for another component of the selector string. This method may remove characters, escape characters, or surround the string in quotes.

Example

// Sanitize text for a search on title and body fields
$q = $input->get->text('q'); // text search query
$results = $pages->find("title|body%=" . $sanitizer->selectorValue($q));

// In 3.0.127 you can also provide an array for the $value argument
$val = $sanitizer->selectorValue([ 'foo', 'bar', 'baz' ]);
echo $val; // outputs: foo|bar|baz

Usage

// basic usage
$string = $sanitizer->selectorValue($value);

// usage with all arguments
$string = $sanitizer->selectorValue($value, $options = []);

Arguments
