Question

我的代码中存在问题。当我尝试在我的应用程序中搜索哪个错误

时

致命错误：未捕获错误：在C：\ xampp \ htdocs \ newspaper \ cpannel \ ajaxcat.php中调用未定义的方法public static function SearchOnCategorya($data) { global $dbh; $sql=$dbh->prepare("select * from category where name like '%$data%'"); if($sql->execute()){ $allcategories = $sql->fetchall(PDO::FETCH_ASSOC); return $allcategories; }else{ return FALSE; } }：210堆栈跟踪：＃0 {main}在C：\ xampp \中抛出第210行的htdocs \ newspaper \ cpannel \ ajaxcat.php

这是我的班级类别代码

$(function (){
      $("#catserch").on("keyup",function (){
          var serach=$(this).val();

          var action="searchcategory";
            $.ajax({
                url: "ajaxcat.php",
                method: "post",
                data: {action: action, serach:serach},
                beforeSend: function () {

                    $(".img-ad").fadeIn();

                },
                success: function (data) {
                    $(".serchresult").html(data);
                    $(".img-ad").fadeOut();
                },
                error: function () {
                    $(".serchresult").html("error");
                    $(".img-ad").fadeOut();

                }
            })
      })
  })

这是jQuery和ajax代码

 case'searchcategory':
      echo  $data=$_POST['serach'];

       echo '<table  class="table table-striped  table-bordered table-hover">
                   <thead>
                    <th>id</th>
                    <th>name</th>
                    <th>manager</th>
                    </thead>
        <tbody>';
       $allcattt= category::SearchOnCategorya($data);
       print_r($allcattt);
       if(is_array($allcattt)&& count($allcattt)>0){
           foreach ($allcattt as $category):
               echo'

                    <td> '.$category['id'].'</td>
                        <td> '.$category['name'].'</td>
                            <td> '.editor::retriveeditornamebyid($category['id_manager']).'</td>

                    </tbody>


               </table>';
           endforeach;
       }else{

       }
        break;

Answer 1

在你的课堂上，你有：

public static function SearchOnCategory($data)

在通话中，您有：

SearchOnCategorya

请注意您的通话中的额外字母a？你拼错了这个函数。

使用PHP和AJAX搜索错误需要意见
