Flux: Fluid FlexForms¶

Flux is a replacement API for TYPO3 FlexForms - with interfaces for Fluid, PHP and TypoScript

Flux lets you build and modify forms in Fluid:

<flux:form id="myform">
  <flux:field.input name="myField" label="My special field" />
</flux:form>

In PHP:

$form = \FluidTYPO3\Flux\Form::create();
$form->setName('myform');
$form->createField('Input', 'myField', 'My special field');

In plain arrays (to allow sources like JSON):

$json = '{name: "myform", fields: [{"name": "myField", "type": "Input"}]}';
$asArray = json_decode($json, JSON_OBJECT_AS_ARRAY);
$form = \FluidTYPO3\Flux\Form::create($asArray);

And in TypoScript:

plugin.tx_flux.providers {
  myextension_myplugin {
    tableName = tt_content
    fieldName = pi_flexform
    listType = myextension_myplugin
    extensionKey = Vendor.MyPlugin
    form {
      name = myform
      fields {
        myField {
          type = Input
          label = My special field
        }
      }
    }
  }
}

All of which create the same form with a single input field called myField with a label value of My special field. The last example shows the form structure nested in a Provider (another Flux concept) which connects the pi_flexform field of the related tt_content plugin record type to the form.
