hook()

Queues up a method to be called by a given template hook.

For example, if you place this in your plugin’s init() method:

Craft::$app->view->hook('myAwesomeHook', function(&$context) {
    $context['foo'] = 'bar';
    return 'Hey!';
});

you would then be able to add this to any template:

{% hook "myAwesomeHook" %}

When the hook tag gets invoked, your template hook function will get called. The $context argument will be the current Twig context array, which you’re free to manipulate. Any changes you make to it will be available to the template following the tag. Whatever your template hook function returns will be output in place of the tag in the template as well.

If you want to prevent additional hook methods from getting triggered, add a second $handled argument to your callback method, which should be passed by reference, and then set it to true within the method.

Craft::$app->view->hook('myAwesomeHook', function(&$context, &$handled) {
    $context['foo'] = 'bar';
    $handled = true;
    return 'Hey!';
});

View source

Arguments

• $hook (string) – The hook name.
• $method (callable) – The callback function.
• $append (boolean) – Whether to append the method handler to the end of the existing method list for the hook. If false, the method will be inserted at the beginning of the existing method list.

init()

Initializes the view component.

View source

invokeHook()

Invokes a template hook.

This is called by \craft\web\HookNode.

View source

Arguments

• $hook (string) – The hook name.
• $context (array) – The current template context.

Returns

string – Whatever the hooks returned.

namespaceInputId()

Namespaces an input ID.

This method applies the same namespacing treatment that namespaceInputs() does to id= attributes, but only to a single value, which is passed directly into this method.

View source

Arguments

• $inputId (string) – The input ID that should be namespaced.
• $namespace (string, null) – The namespace. Defaults to the active namespace.

Returns

string – The namespaced input ID.

namespaceInputName()

Namespaces an input name.

This method applies the same namespacing treatment that namespaceInputs() does to name= attributes, but only to a single value, which is passed directly into this method.

View source

Arguments

• $inputName (string) – The input name that should be namespaced.
• $namespace (string, null) – The namespace. Defaults to the active namespace.

Returns

string – The namespaced input name.

namespaceInputs()

Renames HTML input names so they belong to a namespace.

This method will go through the passed-in $html looking for name= attributes, and renaming their values such that they will live within the passed-in $namespace (or the active namespace). By default, any id=, for=, list=, data-target=, data-reverse-target=, and data-target-prefix= attributes will get namespaced as well, by prepending the namespace and a dash to their values. For example, the following HTML:

<label for="title">Title</label>
<input type="text" name="title" id="title">

would become this, if it were namespaced with “foo”:

<label for="foo-title">Title</label>
<input type="text" name="foo[title]" id="foo-title">

Attributes that are already namespaced will get double-namespaced. For example, the following HTML:

<label for="bar-title">Title</label>
<input type="text" name="bar[title]" id="bar-title">

would become:

<label for="foo-bar-title">Title</label>
<input type="text" name="foo[bar][title]" id="foo-bar-title">

When a callable is passed to $html (supported as of Craft 3.7), the namespace will be set via setNamespace() before the callable is executed, in time for any JavaScript code that needs to be registered by the callable.

$settingsHtml = Craft::$app->view->namespaceInputs(function() use ($widget) {
    return $widget->getSettingsHtml();
}, 'widget-settings');

View source

Arguments

• $html (string, callable) – The HTML code, or a callable that returns the HTML code
• $namespace (string, null) – The namespace. Defaults to the active namespace.
• $otherAttributes (boolean) – Whether id, for, and other attributes should be namespaced (in addition to name)
• $withClasses (boolean) – Whether class names should be namespaced as well (affects both class attributes and class name CSS selectors within <style> tags). This will only have an effect if $otherAttributes is true.

Returns

string – The HTML with namespaced attributes

normalizeObjectTemplate()

Normalizes an object template for renderObjectTemplate().

View source

Arguments

• $template (string)

Returns

string

registerDeltaName()

Since

3.4.0

Registers a delta input name.

This can be either the name of a single form input, or a prefix used by multiple input names.

The input name will be namespaced with the currently active namespace, if any.

When a form that supports delta updates is submitted, any delta inputs (or groups of inputs) that didn’t change over the lifespan of the page will be omitted from the POST request.

Note that delta input names will only be registered if delta registration is active (see getIsDeltaRegistrationActive()).

View source

Arguments

• $position (integer) – The position at which the HTML code should be inserted in the page. Possible values are:
• POS_HEAD: in the head section
• POS_BEGIN: at the beginning of the body section
• POS_END: at the end of the body section

registerJs()

Registers a JS code block.

View source

Arguments

• $js (string) – The JS code block to be registered
• $position (integer) – The position at which the JS script tag should be inserted in a page. The possible values are:

View source

Arguments

• $url (string) – The JS file to be registered.
• $options (array) – The HTML attributes for the script tag. The following options are specially handled and are not treated as HTML attributes:
• $key (string, null) – The key that identifies the JS script file. If null, it will use $url as the key.

resolveTemplate()

Finds a template on the file system and returns its path.

All of the following files will be searched for, in this order:

• TemplateName
• TemplateName.html
• TemplateName.twig
• TemplateName/index.html
• TemplateName/index.twig

If this is a front-end request, the actual list of file extensions and index filenames are configurable via the config3:defaultTemplateExtensions and config3:indexTemplateFilenames config settings.

For example if you set the following in config/general.php:

'defaultTemplateExtensions' => ['htm'],
'indexTemplateFilenames' => ['default'],

then the following files would be searched for instead:

• TemplateName
• TemplateName.htm
• TemplateName/default.htm

The actual directory that those files will depend on the current template mode (probably templates/ if it’s a front-end site request, and vendor/craftcms/cms/src/templates/ if it’s a Control Panel request).

If this is a front-end site request, a folder named after the current site handle will be checked first.

• templates/SiteHandle/...
• templates/...

And finally, if this is a control panel request and the template name includes multiple segments and the first segment of the template name matches a plugin’s handle, then Craft will look for a template named with the remaining segments within that plugin’s templates/ subfolder.

To put it all together, here’s where Craft would look for a template named “foo/bar”, depending on the type of request it is:

• Front-end site requests:
  • templates/SiteHandle/foo/bar
  • templates/SiteHandle/foo/bar.html
  • templates/SiteHandle/foo/bar.twig
  • templates/SiteHandle/foo/bar/index.html
  • templates/SiteHandle/foo/bar/index.twig
  • templates/foo/bar
  • templates/foo/bar.html
  • templates/foo/bar.twig
  • templates/foo/bar/index.html
  • templates/foo/bar/index.twig
• Control panel requests:
  • vendor/craftcms/cms/src/templates/foo/bar
  • vendor/craftcms/cms/src/templates/foo/bar.html
  • vendor/craftcms/cms/src/templates/foo/bar.twig
  • vendor/craftcms/cms/src/templates/foo/bar/index.html
  • vendor/craftcms/cms/src/templates/foo/bar/index.twig
  • path/to/fooplugin/templates/bar
  • path/to/fooplugin/templates/bar.html
  • path/to/fooplugin/templates/bar.twig
  • path/to/fooplugin/templates/bar/index.html
