This class was built for my own need. Decided to share in case someone else needs something like this.

This is meant to be used within a WordPress plugin so make sure you've uploaded this class and all the other files within your plugin's folder.

Then:

require_once( 'class-html-elements.php' );

Next, instantiate the class:

use \AT\HTML_Elements;
$elements = new HTML_Elements;

Now you've got access to the "render" method:

$elements->render( 'checkbox', array(
  'id'    => 'test',
  'name'  => 'test',
  'value' => true,
  'label' => 'Checkbox label',
));

The render method accepts 2 parameters, the field type and an array containing the settings of the field. Here you can find a list of supported parameters.

Additional attributes can be passed to each field type by using the "attributes" parameter. Example:

$elements->render( 'text', array(
  'id'         => 'test',
  'name'       => 'test',
  'value'      => 'something',
  'label'      => 'My text field',
  'attributes' => array( 'attr' => 'value' )
) );
