本文介绍了CodeIgniter + jQuery UI autocomplete = 500内部服务器错误（带代码）的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！问题描述

以下是视图代码：

<html> <head> <script type="text/javascript" src="ajax.googleapis/ajax/libs/jquery/1.5/jquery.min.js"></script>  <script type="text/javascript" src="ajax.googleapis/ajax/libs/jqueryui/1.8/jquery-ui.min.js"></script> <script type="text/javascript"> $( function() { $("#input").autocomplete({ source: function(req, add){ $.ajax({ url: '<?php echo base_url(); ?>test/ac2', dataType: 'json', type: 'POST', //data: req, data: 'input='+req, success: function(data){ if(data.response =='true'){ add(data.message); } } }); }, minLength: 2, select: function(event, ui){ $(this).end().val(ui.item.value); } }); }); </script> </head> <?php echo form_open(); echo form_input('input', '', 'id="input"'); echo form_close(); ?> </html>

和控制器代码：

class Test extends CI_Controller { function index() { $this->load->view('vw/test_vw'); } public function ac2() { //$search = $this->input->post('term'); $search = $this->input->post('input'); $data['response'] = 'false'; $this->db->select('*'); $this->db->from('loc_exercise'); $this->db->like('locations', $search); $locations = $this->db->get()->result(); if (count($locations) > 0) { $data['message'] = array(); foreach ($locations as $location) { $data['message'][] = array( 'label' => $location->locations, 'item' => $location->locations, 'value' => $location->locations ); } $data['response'] = 'true'; } echo json_encode($data); }

当我在输入框中输入任何内容时，

When I type anything in into the input box I get this on the console:

POST my.example/test/ac2 500 (Internal Server Error)

，并且在CI错误日志上似乎没有问题（log_threshold为1，/ logs为chmod 777）。

and on CI error logs there seems to be no issues (log_threshold is 1, /logs is chmod 777).

我有我的config.php与query_strings TRUE和allow_get_array TRUE。

BTW I have my config.php with query_strings TRUE and allow_get_array TRUE.

任何想法如何解决这个问题？ p>

Any ideas how to fix this issue?
