您的问题是您的
$.ajax
POST正在发送
JSON
数据,但您的
PHP
视图正在
$\u POST
中查找项目

要设置
$\u POST
值,请尝试以下操作:

$.ajax({
url:“view.php”,
方法:“张贴”,
数据:“用户id=”+用户id,
成功:功能(数据){
$(“#员工详细信息”).html(数据);
$('#dataModal').modal('show');
}

});请花一点时间阅读:这里没有足够的信息来回答/理解您的问题。对此表示抱歉。我已经改进了我的问题。谢谢你提供的新信息。它帮助我理解您的问题,并编辑您的问题以使您的问题更清楚。您能否将success函数更改为
success:function(data){console.log(data);}
并将所记录的内容发布到控制台。感谢您的解释。我将努力寻找这个答案。谢谢你的回答。它帮助我找出我的代码出了什么问题。再次感谢@Alexander。你的回答很好。
