$sanitizer->array() method

Sanitize array or CSV string to array of strings

If string specified, string delimiter may be pipe ("|"), or comma (","), unless overridden with the 'delimiter' or 'delimiters' option.

Usage

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

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

Arguments

NameType(s)Description
valuearray, string, mixed

Accepts an array or CSV string. If given something else, it becomes first item in array.

sanitizer (optional)string

Optional Sanitizer method to apply to items in the array (default=null, aka none).

options (optional)array

Optional modifications to default behavior: maxItems (int): Maximum items allowed in array (default=0, which means no limit)
The following options are only used if the provided $value is a string:

  • delimiter (string): Single delimiter to use to identify CSV strings. Overrides the 'delimiters' option when specified (default=null)
  • delimiters (array): Delimiters to identify CSV strings. First found delimiter will be used, default=array("|", ",")
  • enclosure (string): Enclosure to use for CSV strings (default=double quote, i.e. ")

Return value

array

Exceptions

Method can throw exceptions on error:

  • WireException - if an unknown $sanitizer method is given


Hooking $sanitizer->array(…)

You can add your own hook events that are executed either before or after the $sanitizer->array(…) method is executed. Examples of both are included below. A good place for hook code such as this is in your /site/ready.php file.

Hooking before

The 'before' hooks are called immediately before each $sanitizer->array(…) method call is executed. This type of hook is especially useful for modifying arguments before they are sent to the method.

$this->addHookBefore('Sanitizer::array', function(HookEvent $event) {
  // Get the object the event occurred on, if needed
  $sanitizer = $event->object;

  // Get values of arguments sent to hook (and optionally modify them)
  $value = $event->arguments(0);
  $sanitizer = $event->arguments(1);
  $options = $event->arguments(2);

  /* Your code here, perhaps modifying arguments */

  // Populate back arguments (if you have modified them)
  $event->arguments(0, $value);
  $event->arguments(1, $sanitizer);
  $event->arguments(2, $options);
});

Hooking after

The 'after' hooks are called immediately after each $sanitizer->array(…) method call is executed. This type of hook is especially useful for modifying the value that was returned by the method call.

$this->addHookAfter('Sanitizer::array', function(HookEvent $event) {
  // Get the object the event occurred on, if needed
  $sanitizer = $event->object;

  // An 'after' hook can retrieve and/or modify the return value
  $return = $event->return;

  // Get values of arguments sent to hook (if needed)
  $value = $event->arguments(0);
  $sanitizer = $event->arguments(1);
  $options = $event->arguments(2);

  /* Your code here, perhaps modifying the return value */

  // Populate back return value, if you have modified it
  $event->return = $return;
});

“We chose ProcessWire because of its excellent architecture, modular extensibility and the internal API. The CMS offers the necessary flexibility and performance for such a complex website like superbude.de. ProcessWire offers options that are only available for larger systems, such as Drupal, and allows a much slimmer development process.” —xport communication GmbH
