Codeigniter 聊天應用程序未提交表單數據並在 javascript 控制台中顯示 500 內部服務器錯誤
[英]Codeigniter Chat Application Not submitting form data and also giving displaying an 500 Internal Server Error in javascript console
問題描述
我正在嘗試使用 codeigniter 框架實現一個聊天應用程序，但是在表單提交時，表單數據沒有被提交，並且提交按鈕被禁用。 當我檢查 javascript 控制台時，我收到錯誤 500 Internal Server Error for the url localhost/biko/chat/conv/xsapSHKs/msg 它應該獲取新消息。 我對 PHP 非常熟悉，但對 ajax 或 javascript 不太好。 任何幫助將不勝感激。 下面是我的控制器、模型和視圖。
控制器（chat.php）
public function conv($slug = FALSE, $action = FALSE) {
$this->form_validation->set_rules('message', 'Message', 'trim|required');
$this->form_validation->set_rules('mid', '', 'trim|required');
$this->form_validation->set_rules('fid', '', 'trim|required');
$this->form_validation->set_rules('id', '', 'trim|required');
if ($slug === FALSE) {
if ($_POST['bcdhgfjhggvgzs'] != '') {
$this->Chat_model->startConv();
redirect('/conv/chat/'.$_POST['bcdhgfjhggvgzs'], 'refresh');
}
} else {
if ($action !== '' and $this->form_validation->run() !== FALSE) {
$this->Chat_model->save($action);
}
$data['pageTitle'] = 'Chat';
$data['pageKeywords'] = 'chat';
$data['pageDescription'] = 'Chat with Us';
$data['converse'] = $this->Chat_model->get_conversations($slug);
$data['ifempty'] = count($data['converse']);
$data['content'] = "chat/chatty";
$this->load->view($this->frontend_template, $data);
}
}
模型

看法
<?php
if ($this->auth_user_id != $converse['from']) { $fid = $this->auth_user_id; } else { $fid = $converse['to']; }
$myid = $this->auth_user_id;
