Sanitize as a field name but with optional subfield(s) like “field.subfield”
- Periods must be present to indicate subfield(s), otherwise behaves same as fieldName() sanitizer.
- By default allows just one subfield. To allow more, increase the $limit argument.
- To allow any quantity of subfields, specify -1.
- To reduce a
field.subfield...combo to justfieldspecify 0 for limit argument. - Maximum length of returned string is (128 + ($limit * 128)).
Available since version 3.0.126.
Example
echo $sanitizer->fieldSubfield('a.b.c'); // outputs: a.b (default behavior)
echo $sanitizer->fieldSubfield('a.b.c', 2); // outputs: a.b.c
echo $sanitizer->fieldSubfield('a.b.c', 0); // outputs: a
echo $sanitizer->fieldSubfield('a.b.c', -1); // outputs: a.b.c (any quantity)
echo $sanitizer->fieldSubfield('foo bar.baz'); // outputs: foo_bar.baz
echo $sanitizer->fieldSubfield('foo bar baz'); // outputs: foo_bar_bazUsage
// basic usage
$string = $sanitizer->fieldSubfield(string $value);
// usage with all arguments
$string = $sanitizer->fieldSubfield(string $value, int $limit = 1);Arguments
