MySQL — Как я могу сделать автозаполнение из списка в переполнении стека
Мне нужна помощь, если ты не против. Я создаю простой faq-сайт для школы, и я добавил раздел администратора, где он может изменять или удалять пользователей. Я создал форму в php, которая имеет один список (lst_id), который выбирает все идентификаторы в базе данных. Дело в том, как я могу заполнить текстовые поля ниже автоматически, когда я выбираю идентификатор из списка? Текстовые поля: txt_name, txt_password и txt_email.
Я использую PHP и MySQL.
Заранее спасибо,

Решение
Я бы отправил вызов AJAX на сервер, используя Javascript с переменной ID, чтобы получить все соответствующие значения, а затем обновить их с помощью JQuery — чтобы сделать это без перезагрузки страницы

Другие решения
Простейшее решение этой проблемы — установить lst_id в URL при смене флажка.
а затем в своем коде проверьте, установлен ли список идентификаторов, если да, то извлеките все записи для идентификатора и отобразите его в текстовых полях.
код JavaScript:
$("#lst_id").on('change',function(){
window.loaction = window.location.href+'?list_id='+$("#lst_id").val();
})
PHP-код:
if(isset($_GET['lst_id'])){
// write query to fetch entries for that list id
}
И чем просто установить значение для ваших текстовых полей

<script type="text/javascript">
//<![CDATA[
$(document).ready(function() {
$("#idoftextbox").on('change',function(){
GetData();
})
}
function GetData() {
$.ajax({
url: 'linktophpfilewithconnectiontodatabase.php',
data: "{ id: '" + $('#idoftextbox').val() + "' } ",
contentType: "application/json; charset=utf-8",
type: 'post',
success: fillboxes,
error: showError
});
}
function showError(data, status) {
//do your stuff
}
function fillboxes(data, status) {
//with your php you should have sent back a json encoded string, download a debugger of your choice (ie firefox) and find out which attribute of data you need to decode, then just
$("#textboxid1").val(extractedvalues[0]);
$("#textboxid2").val(extractedvalues[1]);
}
