class SearchForm extends Form (View source)

Standard basic search form which conducts a fulltext search on all SiteTree objects.

If multilingual content is enabled through the Translatable extension, only pages the currently set language on the holder for this searchform are found. The language is set through a hidden field in the form, which is prepoluated with Translatable::get_current_locale() when then form is constructed.

protected registerExtraMethodCallback(string $name, callable $callback)

Register an callback to invoke that defines extra methods

Parameters

string $name
callable $callback

bool hasMethod(string $method)

Return TRUE if a method exists on this object

This should be used rather than PHP's inbuild method_exists() as it takes into account methods added via extensions

Parameters

protected constructExtensions() deprecated

deprecated 4.0.0:5.0.0 Extensions and methods are now lazy-loaded

No description

protected defineExtensionMethods()

Adds any methods from Extension instances attached to this object.

All these methods can then be called directly on the instance (transparently mapped through __call()}), or called explicitly through {@link extend().

static bool add_extension(string $classOrExtension, string $extension = null)

Add an extension to a specific class.

The preferred method for adding extensions is through YAML config, since it avoids autoloading the class, and is easier to override in more specific configurations.

As an alternative, extensions can be added to a specific class directly in the Object::$extensions array. See SiteTree::$extensions for examples. Keep in mind that the extension will only be applied to new instances, not existing ones (including all instances created through singleton()).

Parameters

string $classOrExtension

Class that should be extended - has to be a subclass of Object

string $extension

Subclass of Extension with optional parameters as a string, e.g. "Versioned" or "Translatable('Param')"

Return Value

bool

Flag if the extension was added

See also

http://doc.silverstripe.org/framework/en/trunk/reference/dataextension

static remove_extension(string $extension)

Remove an extension from a class.

Note: This will not remove extensions from parent classes, and must be called directly on the class assigned the extension.

Keep in mind that this won't revert any datamodel additions of the extension at runtime, unless its used before the schema building kicks in (in your _config.php). Doesn't remove the extension from any Object instances which are already created, but will have an effect on new extensions. Clears any previously created singletons through singleton() to avoid side-effects from stale extension information.

Add support for removing extensions with parameters

Parameters

string $extension

class name of an Extension subclass, without parameters

static array get_extensions(string $class = null, bool $includeArgumentString = false)

No description

Parameters

string $class

If omitted, will get extensions for the current class

bool $includeArgumentString

Include the argument string in the return array, FALSE would return array("Versioned"), TRUE returns array("Versioned('Stage','Live')").

Return Value

array

Numeric array of either DataExtension class names, or eval'ed class name strings with constructor arguments.

static array|null get_extra_config_sources(string $class = null)

Get extra config sources for this class

Parameters

string $class

Name of class. If left null will return for the current class

Return Value

array|null

static bool has_extension(string $classOrExtension, string $requiredExtension = null, bool $strict = false)

Return TRUE if a class has a specified extension.

This supports backwards-compatible format (static Object::has_extension($requiredExtension)) and new format ($object->has_extension($class, $requiredExtension))

Parameters

string $classOrExtension

Class to check extension for, or the extension name to check if the second argument is null.

string $requiredExtension

If the first argument is the parent class, this is the extension to check. If left null, the first parameter will be treated as the extension.

bool $strict

if the extension has to match the required extension and not be a subclass

Return Value

bool

Flag if the extension exists

array invokeWithExtensions(string $method, mixed $a1 = null, mixed $a2 = null, mixed $a3 = null, mixed $a4 = null, mixed $a5 = null, mixed $a6 = null, mixed $a7 = null)

Calls a method if available on both this object and all applied Extensions, and then attempts to merge all results into an array

Parameters

string $method

the method name to call

mixed $a1
mixed $a2
mixed $a3
mixed $a4
mixed $a5
mixed $a6
mixed $a7

Return Value

array

List of results with nulls filtered out

array extend(string $method, mixed $a1 = null, mixed $a2 = null, mixed $a3 = null, mixed $a4 = null, mixed $a5 = null, mixed $a6 = null, mixed $a7 = null)

Run the given function on all of this object's extensions. Note that this method originally returned void, so if you wanted to return results, you're hosed

Currently returns an array, with an index resulting every time the function is called. Only adds returns if they're not NULL, to avoid bogus results from methods just defined on the parent extension. This is important for permission-checks through extend, as they use min() to determine if any of the returns is FALSE. As min() doesn't do type checking, an included NULL return would fail the permission checks.

The extension methods are defined during __construct()} in {@link defineMethods().

Parameters

string $method

the name of the method to call on each extension

mixed $a1
mixed $a2
mixed $a3
mixed $a4
mixed $a5
mixed $a6
mixed $a7

Return Value

array

Extension|null getExtensionInstance(string $extension)

Get an extension instance attached to this object by name.

Parameters

string $extension

Return Value

Extension|null

bool hasExtension(string $extension)

Returns TRUE if this object instance has a specific extension applied in $extension_instances. Extension instances are initialized at constructor time, meaning if you use add_extension() afterwards, the added extension will just be added to new instances of the extended class. Use the static method has_extension() to check if a class (not an instance) has a specific extension.

Caution: Don't use singleton()->hasExtension() as it will give you inconsistent results based on when the singleton was first accessed.

Parameters

string $extension

Classname of an Extension subclass without parameters

Return Value

bool

Extension[] getExtensionInstances()

Get all extension instances for this specific object instance.

See get_extensions() to get all applied extension classes for this class (not the instance).

This method also provides lazy-population of the extension_instances property.

Return Value

Extension[]

Map of DataExtension instances, keyed by classname.

static Injectable create(mixed ...$args)

An implementation of the factory method, allows you to create an instance of a class

This method will defer class substitution to the Injector API, which can be customised via the Config API to declare substitution classes.

This can be called in one of two ways - either calling via the class directly, or calling on Object and passing the class name as the first parameter. The following are equivalent: $list = DataList::create(SiteTree::class); $list = SiteTree::get();

Parameters

mixed ...$args

Return Value

Injectable

static Injectable singleton(string $class = null)

Creates a class instance by the "singleton" design pattern.

It will always return the same instance for this class, which can be used for performance reasons and as a simple way to access instance methods which don't rely on instance data (e.g. the custom SilverStripe static handling).

Parameters

string $class

Optional classname to create, if the called class should not be used

Return Value

Injectable

The singleton instance

ValidationResult validationResult()

Processing that occurs before a form is executed.

This includes form validation, if it fails, we throw a ValidationException

This includes form validation, if it fails, we redirect back to the form with appropriate error messages. Always return true if the current form action is exempt from validation

Triggered through httpSubmission().

Note that CSRF protection takes place in httpSubmission(), if it fails the form data will never reach this method.

Return Value

ValidationResult

$this loadDataFrom(array|DataObject $data, int $mergeStrategy = 0, array $fieldList = null)

Load data from the given DataObject or array.

It will call $object->MyField to get the value of MyField. If you passed an array, it will call $object[MyField]. Doesn't save into dataless FormFields (DatalessField), as determined by FieldList->dataFields().

By default, if a field isn't set (as determined by isset()), its value will not be saved to the field, retaining potential existing values.

Passed data should not be escaped, and is saved to the FormField instances unescaped. Escaping happens automatically on saving the data through saveInto().

Escaping happens automatically on saving the data through saveInto().

Parameters

array|DataObject $data
int $mergeStrategy

For every field, $data is interrogated whether it contains a relevant property/key, and what that property/key's value is.

By default, if $data} does contain a property/key, the fields value is always replaced by {@link $data's value, even if that value is null/false/etc. Fields which don't match any property/key in $data are "left alone", meaning they retain any previous value.

You can pass a bitmask here to change this behaviour.

Passing MERGE_CLEAR_MISSING means that any fields that don't match any property/key in $data are cleared.

Passing MERGE_IGNORE_FALSEISH means that any false-ish value in $data won't replace a field's value.

Passing MERGE_AS_INTERNAL_VALUE forces the data to be parsed using the internal representation of the matching form field. This is helpful if you are loading an array of values retrieved from Form::getData() and you do not want them parsed as submitted data. MERGE_AS_SUBMITTED_VALUE does the opposite and forces the data to be parsed as it would be submitted from a form.

For backwards compatibility reasons, this parameter can also be set to === true, which is the same as passing MERGE_CLEAR_MISSING

array $fieldList

An optional list of fields to process. This can be useful when you have a form that has some fields that save to one object, and some that save to another.

Return Value

$this

saveInto(DataObjectInterface $dataObject, FieldList $fieldList = null)

Save the contents of this form into the given data object.

It will make use of setCastedField() to do this.

Parameters

DataObjectInterface $dataObject

The object to save data into

FieldList $fieldList

An optional list of fields to process. This can be useful when you have a form that has some fields that save to one object, and some that save to another.

array getData()

Get the submitted data from this form through FieldList->dataFields(), which filters out any form-specific data like form-actions.

Calls FormField->dataValue() on each field, which returns a value suitable for insertion into a DataObject property.

Return Value
