$sanitizer

Properties and Methods

$sanitizer->email($value) Sanitizes a value for an email address, then filters it. If not valid after sanitization, this function returns a blank string. more

$sanitizer->fieldName($value) Sanitizes a value for a Field name. Same as the name() filter, except that it doesn't allow dashes. more

$sanitizer->name($value) Sanitizes a value for a ProcessWire name, meaning all characters except for these ASCII characters: "a-zA-Z0-9_." (not including the quotes) are removed. It also truncates the length to 128 characters. more

$sanitizer->pageName($value) Sanitizes a value for a URL friendly Page name. Same as the name() filter, except that it converts uppercase to lowercase, and it attempts UTF-8 to ASCII conversion. more

$sanitizer->pageName($value, true) Sanitizes a value for a URL friendly Page name and cleans out leading or trailing dashes, and converts double dashes to single dashes. Use this if you are passing in a headline to convert to a page name (for example).

If second parameter is "Sanitizer::translate" it will use the language char conversion defined in InputfieldPageName module settings. more

$sanitizer->selectorField($value) Sanitizes a field name as used in a selector value. This function is only necessary if you are dealing with user submitted field names. This is rarely the case in the author's experience, but provided here for consistency with selectorValue() more

$sanitizer->selectorValue($value) Sanitizes a string that needs to appear in a selector value. Replaces disallowed characters with spaces. If value is not already quoted, it will add quotes if it determines they are necessary (like if it contains commas). It limits the length to 100 characters (multibyte safe). more

$sanitizer->text($value) Sanitize a single line of input text. Removes tags, removes newline characters, and truncates length to 1024 characters. This is multibyte safe if your PHP has multibyte support. more

$sanitizer->text($value, $options) Same as the above, except you may provide an $options array to change the behavior. You may specify one or more options in the $options array. See the reference of $options later in this page. more

$sanitizer->textarea($value) Same as the text() function above, except that multiple lines are allowed and maxLength is 16k. more

$sanitizer->textarea($value, $options) Same as textarea() except that you may modify the options documented later in this page, noting that multiLine is already true, and maxLength is already 16384. more

$sanitizer->url($value) Filters a URL value. Returns a valid URL or blank if it can't be made valid. If URL contains a domain and is valid but missing a protocol (like http://) it will add it. It won't add a protocol to local/relative URLs. more

$sanitizer->username($value) Sanitizes a value for a User name, meaning all characters except for these ASCII characters "a-zA-Z0-9-_.@" (not including the quotes) are removed. It also truncates the length to 50 characters.

Deprecated since 2.4 uses sanitizer pageName(). more

// set to true to allow multiple lines
'multiLine' => false,
// maximum allowed characters for multibyte strings
