Question

此代码适用于localhost，但不适用于真实的Chrome开发人员工具，显示该值已发送，状态代码：200 OK。但该值未达到php页面。关于mozilla开发人员工具说json.PARSE：意外的无空白。但是在文本或空格之前和之后都没有任何内容。我在同一文件夹中的所有文件。

$(document).ready(function(){
    // sending id from portfolio to ajax for display modal carousel
    $('.view').on('click', function(e){

        var id2 = $(this).find('a').attr('id');

        $('.getValueHere').empty(); // empty the div before fetching and adding new data

       $.ajax({
       type: "POST",
       url: "ajax.php",
       data: { 'id': id2 },
       success: function(data){
            $('.getValueHere').append(data.result);
       },
       error: function(){
           alert("error");
       }
     });

});

}）;

这里是php页面

header("Content-Type: application/json; charset=UTF-8");
 include_once("database/db.php"); 
    $db = new connection();
    $db = $db->dbConnection();

    /*******************************************************************

    *   portfolio carousel img 
    ********************************************************************/


    $id = $_POST["id"]; // this post id never comes here



    $check = $db->prepare("SELECT * FROM website_articles where id='".$id."'");
        $check->execute();

            $result = array();

            while($row = $check->fetch(PDO::FETCH_ASSOC)) {

                // SLIDE IMAGE
                $image = $row['img_url_slider'];

                $image = explode(',',$image);

                // SLIDE TECHNIQS

                $tech = $row['teknologies'];

Answer 1

删除它并查看错误是否消失。

html_entity_decode($desc)

如果它消失，请尝试：

html_entity_decode($desc,ENT_QUOTES)

Answer 2

可能是因为您的标头已在其他位置设置。您是否尝试注释掉标题以查看是否可以解决问题？同时启用php错误以显示不允许代码继续的任何隐藏错误。希望这会有所帮助！

ajax-php适用于localhost但不适用于realhost
