# LMS Forms Builder

## Filters

1. **`stm_lms_profile_form_default_fields_info`**

**Description:**\
This filter allows you to modify or extend the **default fields** of the Profile Form inside the Form Builder. It is useful when you need to add new input fields or update existing ones for student or instructor profiles.

**Parameters:**

* `$profile_form` (Array) — An array of existing form fields with their configuration.

**Example usage:**

```php
add_filter( 'stm_lms_profile_form_default_fields_info', 'stm_lms_profile_form_default_fields_info_function', 10, 1);		
function stm_lms_profile_form_default_fields_info_function( $profile_form ) {
$profile_form[] = array(
   'first_name'  => array(
      'label'       => esc_html__( 'First Name', 'masterstudy-lms-learning-management-system-pro' ),
      'placeholder' => esc_html__( 'Enter your name', 'masterstudy-lms-learning-management-system-pro' ),
   )
);

return $profile_form;
} 
```

**Explanation:**\
This example adds a new field called **First Name** to the Profile Form. The label defines what users see next to the field, while the placeholder defines the input hint inside the field.

2. **`stm_lms_form_builder_available_fields`**

**Description:**\
This filter allows you to modify or extend the **available field types** in the Form Builder. Developers can add new field types (text, textarea, dropdown, etc.) that instructors or admins can use when building forms.

**Parameters:**

* `$fields` (Array) — An array of all available field types in the form builder.

**Example usage:**

```php
add_filter( 'stm_lms_form_builder_available_fields', 'stm_lms_form_builder_available_fields_function', 10 , 1);
function stm_lms_form_builder_available_fields_function($fields){
$fields[] = array(
   'type'       => 'textarea',
   'field_name' => esc_html__( 'Text Area', 'masterstudy-lms-learning-management-system-pro' ),
);

return $fields;
}
```

**Explanation:**\
This example registers a new **Textarea** field type in the Form Builder. Once added, administrators can use it as a drag-and-drop field when creating custom forms.
