蛋糕php 500内部服务器错误

Question

这是我的自动完成视图代码，但它显示我500内部服务器错误

如果我没有使用正确的网址或其他问题，我不确定会出现什么问题。

public function search(){

$this->loadComponent('RequestHandler');
if ($this->request->is('ajax')) 
{

  $name = $this->request->query['term'];

  $resultArr = $this->Invoices

  ->find()

  ->where(
    ['Invoices.name LIKE' => ($name . '%')],
    ['Invoices.name' => 'string']);
    $resultsArr = [];

    foreach ($resultArr as $result) 
    {
         $resultsArr[] = ($result['name']);
    }

    $this->set('resultsArr', $resultsArr);
    // This line is what handles converting your array into json
    // To get this to work you must load the request handler
    $this->set('_serialize', ['resultsArr']);


}
}

这是我的观看代码：

 <?php echo $this->Form->input('name', ['type' => 'text']); ?>
    $.ajax({
    type:       "POST",
    url:        "<?php echo Router::url(array('controller' => 'Clinics','action' => 'search')); ?>",
    success:    function(response) {
        $("#name").autocomplete({ source: response });
    }
     });

Answer 1

根据注释中的错误消息，未定义loadComponent方法。

我建议在控制器顶部附近加载RequestHandler组件，例如：

class ClinicController extends AppController {
    public $components = array('Request');

还有另一种动态加载组件的语法：

$this->Request = $this->Components->load('Request');
