TwigForm

Twig function form_open

Twig function to open an HTML form by a provisioned <form> tag.

Usage:

{{ form_open( attributes ) }}

The parameter attributes is a dictionary (key-value-list) for provisioning the <form> tag.

Key-names can be all valid attribute names of the <form> tag, see w3schools.com.

Some specials do exist:

• method defaults to POST; if not GET or POST, an additional _method input of hidden type will be added.
• You can add the additional attribute token, if you want to add a hidden input with the name _token e.g. to use your CSRF token within the form.
• If no enctype attribute is given, this extension uses multipart/form-data by default.
• Since this extension is part of TwigForm, which uses Bootstrap (version 5) for styling, our form class attribute defaults to form-horizontal – please adjust for your needs.
• You can also add only additional classes without overriding the already mentioned class attribute by using add_class attribute – it takes one string to be appended to the actual class attribute

Twig function form_close

Twig function that returns a </form> tag; closing of form_open function.

Usage:

{{ form_close() }}

Twig function request_data

Twig function that returns a value out of the default global $_REQUEST, $_GET or $_POST variables.

Usage:

{{ request_data( name [, default [, method ]] ) }}

• name is the string value of the name to be looked for
• default (optional) is a default value to be returned, if variable does not exist
• method (optional) represents the specific method to be looked into – GET, POST or REQUEST. If no value given, the function defaults it to NULL and then will use $_REQUEST for lookup.
