Name filter for ProcessWire filenames (basenames only, not paths)
This sanitizes a filename to be consistent with the name format in ProcessWire, ASCII-alphanumeric (a-z A-Z 0-9), hyphens, underscores and periods. Note that
filenames may contain mixed case (a-z A-Z) so if you require lowercase then
run the return value through a strtolower() function.
Example
// outputs: FileName.jpg
echo $sanitizer->filename('©®™FileName.jpg');
// outputs: c_r_tmfilename.jpg
echo strtolower($sanitizer->filename('©®™filename.jpg', Sanitizer::translate));Usage
// basic usage
$string = $sanitizer->filename(string $value);
// usage with all arguments
$string = $sanitizer->filename(string $value, $beautify = false, int $maxLength = 128);Arguments
| Name | Type(s) | Description |
|---|---|---|
value | string | Filename to sanitize |
beautify (optional) | bool, int | Should be true when creating a file's name for the first time. Default is false. You may also specify Sanitizer::translate (or number 2) for the $beautify param, which will make it translate letters based on the InputfieldPageName custom config settings. |
maxLength (optional) | int | Maximum number of characters allowed in the filename |
Return value
