$sanitizer->fieldName() method

Sanitize consistent with names used by ProcessWire fields and/or PHP variables

  • Allows upper and lowercase ASCII letters, digits and underscore.
  • ProcessWire field names follow the same conventions as PHP variable names, though digits may lead.
  • This method is the same as the varName() sanitizer except that it supports beautification and max length.
  • Unlike other name formats, hyphen and period are excluded because they aren't allowed characters in PHP variables.

Example

$test = "Hello world";
echo $sanitizer->fieldName($test); // outputs: Hello_world

Usage

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

// usage with all arguments
$string = $sanitizer->fieldName(string $value, $beautify = false, int $maxLength = 128);

Arguments

Value you want to sanitize

Maximum number of characters allowed in the name (default=128).
