/ 08 апреля 2020

Я хочу получить идентификатор данных в php, чтобы обновить их в моей базе данных. Я перепробовал много вещей, которые нашел в Интернете, но не смог решить проблему. Вот ВСЕ код для редактирования.

Здесь отображаются сообщения, но я не знаю, как получить идентификатор для каждого сообщения, чтобы люди могли редактировать / редактировать mysql

<?php

$link = mysqli_connect ('localhost', 'root', '', '');

mysqli_select_db ($link, 'CodersHome');

?>

<?php
session_start ();
if( !isset($_SESSION['username']))
header('location:../login.php');
 ?>

Здесь вы можете увидеть, где я пытаюсь обновить.

Я хочу обновить данные в таблице. У меня также есть идентификатор, назначенный для каждой строки, но я не знаю, как получить идентификатор для редактирования точной строки таблицы.

Также здесь приведена живая демонстрация того, где сообщение создается и воспроизводится. 

function openCity(evt, cityName) {
  var i, tabcontent, tablinks;
  tabcontent = document.getElementsByClassName("tabcontent");
  for (i = 0; i < tabcontent.length; i++) {
    tabcontent[i].style.display = "none";
  }
  tablinks = document.getElementsByClassName("tablinks");
  for (i = 0; i < tablinks.length; i++) {
    tablinks[i].className = tablinks[i].className.replace(" active", "");
  }
  document.getElementById(cityName).style.display = "block";
  evt.currentTarget.className += " active";
}

Ошибка, которую вы допустили, заключалась в том, что вы закрыли пока l oop. Кроме того, выведите i наружу для лучшего подхода. 

$i=0;
while($row = mysqli_fetch_array($result))  {

//echo $row["title"];
//echo $row["description"];
//echo $row["datef"];


$sql = "UPDATE agenda SET title = $title, description = $desc, datef = $date1, inserter = $inserter WHERE id = $row[id]; ";
  $i++;
if(mysqli_query($link, $sql)){
header("Refresh:0; url=agenda.php");
}
}
?>
