Ich habe gesucht und suchte nach der Antwort auf diese Frage und ähnliche Fragen, aber ich war erfolglos. Ich habe eine Datenbank, und eine Option, die mir erlaubt, Einträge in der Datenbank zu bearbeiten und zu löschen, kann ich Einträge vollständig löschen, aber ich kann nicht scheinen, sie zu bearbeiten, ich habe den Code beigefügt, wenn jemand überhaupt eine Idee hat Es wäre erstaunlich, vielen Dank im Voraus.Bearbeiten von MySQL-Einträgen mit PHP
<?php
require_once('includes/connection.php');
// initialize flags
$OK = false;
$done = false;
// get details of selected record
//if (isset($_GET['band_id']) && !$_POST) {
if (isset($_GET['band_id'])) {
// prepare SQL query
$sql = 'SELECT band_id, email, bandname, bio, state, genre, link, sound FROM submit
WHERE band_id = ?';
$stmt = $conn->prepare($sql);
// bind the results using numbers to reference the columns used in the select statement

Fehlermeldungen? ist '$ _POST ['update']' set, was bedeutet 'aber ich bin nicht erfolgreich 'bedeutet – ArtisticPhoenix
Nur aus dem Lesen dieses' $ _POST ['band_id']' sollte als letztes in Ihrem execute Array sein, damit '?' markiert. – ArtisticPhoenix
Ich würde auch versuchen, das Codebeispiel minimal zu machen. Hier ein paar irrelevante Codes. –
