HTML 按钮调用控制器/操作

我正在尝试在 Yii 中创建 html 按钮，点击按钮我想调用 UserController.php 和 Actioncreate 。

我正在这样做，

 echo CHtml::button('Signup', array('button' => array('Users/create'))); ?>

但它给了我以下错误

htmlspecialchars() expects parameter 1 to be string, array given 

这是堆栈跟踪

谁能告诉我这个错误的含义是什么，并指导我解决方案？

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键/值对的数组，而不是数组的数组（就像您在示例中那样）参见CHtml::按钮() http://www.yiiframework.com/doc/api/1.1/CHtml#button-detail了解更多信息。使用此方法的一种方式是：

echo CHtml::button('myButton',array(
    'class' => 'buttonClass',
    'id'    => 'buttonId',
));

这会输出类似：

<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CHtml::提交按钮() http://www.yiiframework.com/doc/api/1.1/CHtml#submitButton-detail它将提交其中包含的表格。

如果您想要一个按钮将用户实际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。

如果是这种情况，这里有一个问题和几个可能对您有所帮助的答案：如何使用 jQuery 或 Javascript 将按钮重定向到另一个页面 https://stackoverflow.com/questions/2238368/how-to-make-a-button-redirect-to-another-page-using-jquery-or-just-javascript
