Details

__construct(DOMElement $node, string $currentUri, string|null $method = null, string $baseHref = null)

string|null $method The method to use for the link (GET by default)
string $baseHref The URI of the used for relative links, but not for empty action

Gets the form method.

If no method is defined in the form, GET is returned.

Return Value

string The method

string getUri()

The returned URI is not the same as the form "action" attribute. This method merges the value if the method is GET to mimics browser behavior.

Return Value

string The URI

protected string getRawUri()

Returns raw URI data.

Return Value

string

protected string canonicalizePath(string $path)

Returns the canonicalized URI path (see RFC 3986, section 5.2.4).

string $path URI path

Return Value

string

protected setNode(DOMElement $node)

Sets the node for the form.

Expects a 'submit' button \DOMElement and finds the corresponding form element, or the form element itself.

Parameters

DOMElement $node A \DOMElement instance

Exceptions

LogicException If given node is not a button or input or does not have a form ancestor

DOMElement getFormNode()

Gets the form node associated with this form.

Return Value

DOMElement A \DOMElement instance

$this setValues(array $values)

Sets the value of the fields.

Parameters

array $values An array of field values

Return Value

$this

array getValues()

Gets the field values.

The returned array does not include file fields (see getFiles).

Return Value

array An array of field values

array getFiles()

Gets the file field values.

Return Value

array An array of file field values

array getPhpValues()

Gets the field values as PHP.

This method converts fields with the array notation (like foo[bar] to arrays) like PHP does.

Return Value

array An array of field values

array getPhpFiles()

Gets the file field values as PHP.

This method converts fields with the array notation (like foo[bar] to arrays) like PHP does. The returned array is consistent with the array for field values (see getPhpValues), rather than uploaded files found in $_FILES. For a compound file field foo[bar] it will create foo[bar][name], instead of foo[name][bar] which would be found in $_FILES.

Return Value

array An array of file field values

bool has(string $name)

Returns true if the named field exists.

Parameters

string $name The field name

Return Value

bool true if the field exists, false otherwise
