我已经在网上搜索过这个，但仍然没有任何进展。我只是想向同一个 URL 提交一个表单，但它只是说“加载页面错误”，并且控制台显示“加载资源失败：服务器响应状态为 500（内部服务器错误）”。我已经独立测试了控制器代码，没有错误。
我在网上找到的是设置表单属性“data-ajax=false”，但这只会导致另一个问题：提交表单后页面完全空白。
以下是代码：
查看（省略了页眉和页脚，仅加载了一些包装器和 js 和 css 文件）：
<?php if (validation_errors()): ?>
<p><?php echo validation_errors(); ?></p>
<?php endif; ?>

我试过$this->output->set_output()and echo，但仍然是“加载页面错误”。
我正在使用 CodeIgniter 2.1.4、jQuery 2.0.3 和 jQueryMobile 1.3.2。
