有谁能告诉我这个错误的含义,并指导我找到解决方案吗?CHtml button()方法实际上只是一个按钮,它接受的第二个参数应该是一个键/值对数组,而不是一个数组数组(如示例中所示),有关详细信息,请参阅。使用这种方法的一种方法是:
echo CHtml::button('myButton',array(
'class' => 'buttonClass',
'id' => 'buttonId',
));
这将输出如下内容:
<input class="buttonClass" id="buttonId" name="yt1" type="button" value="myButton">
如果您想要一个按钮来提交表单,您可以使用该按钮来提交表单所包含的表单
如果您想要一个按钮将用户重定向到一个单独的页面而不提交任何内容,那么我认为最好的解决方案是使用带有锚链接的图像,或者在按下按钮后使用jQuery重定向用户
如果是这样的话,这里有一个问题和几个答案可能会帮助你:
