// Display checkbox, initially checked. $checked_value = 1; $checkbox1 = new XoopsFormCheckBox(, 'box1', $checked_value); $checkbox1->addOption($checked_value, _MD_MODNAME_CHECK_ME); $form->addElement($checkbox1);
// Display checkbox, initially unchecked. $checked_value = 1; $checkbox2 = new XoopsFormCheckBox(, 'box2', !$checked_value); $checkbox2->addOption($checked_value, _MD_MODNAME_CHECK_ME); $form->addElement($checkbox2);
Assuming the form's method is POST:
If box 1 is checked, the submitted form will have $_POST['box1'] = 1. Otherwise $_POST['box1'] will be undefined.
If box 2 is checked, the submitted form will have $_POST['box2'] = 1. Otherwise $_POST['box2'] will be undefined.
