$element = new Varien_Data_Form_Element_Text(array( 'name' => 'my_element', 'label' => 'My Element', 'class' => 'my-class', )); $htmlId = $element->getHtmlId(); echo $htmlId; // Outputs something like "my-element-93"
$fieldset = new Varien_Data_Form_Element_Fieldset(array( 'name' => 'my_fieldset', 'label' => 'My Fieldset', )); $checkbox = new Varien_Data_Form_Element_Checkbox(array( 'name' => 'my_checkbox', 'label' => 'My Checkbox', )); $fieldset->addElement($checkbox); $htmlId = $checkbox->getHtmlId(); echo $htmlId; // Outputs something like "my-fieldset-my-checkbox-71"This example creates a fieldset element and a checkbox element, then adds the checkbox to the fieldset. The getHtmlId() method is called on the checkbox element to retrieve its unique HTML ID, which includes both the fieldset and checkbox names. In both examples, the `Varien_Data_Form_Element_Abstract` class is used to create and manipulate form elements. This class is part of the Magento library.
