Question

我有多个复选框可以查看数据库中的爱好名称，并且它正在运行。但我需要将所选爱好名称的id存储在数据库中。但是当我选择任何爱好名称时，它只在我的数据库表中存储0。

我有一个Hobbies表，我也为此创建了一个模型。请任何人帮忙。

这是在 views / sample / register.php 文件

中

<?php

如果您查看foreach循环生成的html，您会看到所有复选框都具有相同的名称和ID。因此，只有其中一个将存在于$ _POST数组中，因为该名称用作键。

要解决此问题，请将name更改为数组：

echo $form->checkBox($model, 'hobby[]');

或者，您可以在评论代码中使用CActiveForm::checkBoxList并使用template设置样式：

template：string，指定每个复选框的呈现方式。默认为＆＃34; {input} {label}＆＃34;，其中＆＃34; {input}＆＃34;将被生成的复选框输入标记替换为＆＃34; {label}＆＃34;将被相应的复选框标签替换。

echo $form->checkBoxList(
    $model, 
    'hobby', 
    CHtml::listData(Hobbies::model()->findAll(), 'hobby_id', 'hobby_name'), 
    array('template' => '{input}{label}<br/>')
);

尝试在yii中存储数据库中多个复选框的id时出错
