我在實(shí)現(xiàn)可以編輯用戶角色的編輯功能時(shí)遇到問題這是將打開模態(tài)的按鈕<button type="button" id="edit" name="edit" class="btn btn-outline-warning" data-id="'.$row["id"].'">EDIT</button>這是模態(tài)代碼<div class="modal fade" id="editModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true"> <div class="modal-dialog" role="document"> <div class="modal-content"> <div class="modal-header"> <h5 class="modal-title">Edit User</h5> <button type="button" class="close" data-dismiss="modal" aria-label="Close"> <span aria-hidden="true">×</span> </button> </div> <div class="modal-body"> <form method="post" action=""> <div class="form-group"> <label for="userName" class="col-form-label">Username:</label> <input type="text" class="form-control border-danger" id="userName" readonly style="background-color: #2A3038"> </div> <div class="form-group"> <label for="user_type" class="col-form-label">User Type:</label> <select class="form-control border-success" id="user_type"> <option value="user">User</option> <option value="contributor">Contributor</option> </select> </div> </form> </div> <div class="modal-footer"> <input type="hidden" id="user_id" name="user_id"> <button type="submit" id="update" name="update" class="btn btn-success">Update</button> <button type="button" class="btn btn-light" data-dismiss="modal">Close</button> </div> </div> </div></div>而且我還有一個(gè) fetch 函數(shù)，我將它命名為 load_user_data()我遇到的問題是 PHP 操作代碼不起作用，或者我的代碼有什么問題？但我沒有在模態(tài)中顯示數(shù)據(jù)的問題，除非我提交更改沒有功能發(fā)生

您的 ajax 數(shù)據(jù)屬性缺少很多參數(shù)：
....ajax....
data: {user_id: user_id, userName: username here,user_type:set type here, action: 'update'}
您需要在更新按鈕中添加編輯 ID
您還需要將 userdata 添加到您的 ajax 響應(yīng)中，目前您正在使用 data.userName 等，但您沒有將其放入響應(yīng)中
您可以在此處找到有關(guān)如何正確返回 json 響應(yīng)的更多信息： 從 PHP 腳本返回 JSON
