我需要更改包装div上的CSS类名称，因此尝试使用CakePHP book中的setTemplates示例。
我刚从示例中复制并粘贴了以下几行：
$myTemplates = [
'inputContainer' => '<div class="form-control">{{content}}</div>',
];
$this->Form->setTemplates($myTemplates);
运行代码后，我不断收到Array to string conversion警告。代码仍然有效，但是这个警告很烦人，因为它打开了调试，打破了布局。由于这个愚蠢的警告，我不想关闭调试。关于如何摆脱它的任何提示？
