Question

我正在使用单选按钮从可能的选项数量中选择正确的选项。目前我对问题陈述有四种选择，但可能的答案选项可能会增加。我面临的问题是以下代码仅适用于最后一个选项，否则它在表单提交时给出0值。另外请建议我如何使用radioButtonList和以下代码，因为我想在不同的DIV中显示单选按钮。请检查以下代码和建议。在此先感谢

Answer 1

如果您没有使用radioButtonList，则必须将每个radioButton的uncheckValue设置为null。

Answer 2

因为activeRadioButton正在为每个复选框/无线电生成具有相同名称的无敌输入字段（因此以前的值会被表单数据中的此字段覆盖）。应用uncheckValue => null删除此字段。 请记住，如果不使用此字段，请不要选择任何收音机/复选框而不是表单数据，否则将无键correct_option 。

<?php
echo $form->radioButton(
    $model,
    'correct_option',
    array(
        'value' => '4',
        'uncheckValue' => null,
    )
);
?>
