Update und Delete-Tabelle Informationen mit php

Mein Problem ist: Wenn ich auf die Schaltfläche Löschen oder Aktualisieren von drücken, sie die Informationen der Textfelder löschen, und sonst nichts tun, sie zeigen keine error.I Bin neu im programmieren, wenn mir jemand helfen kann, wäre ich dankbar.

P.S: Entschuldigung für mein schlechtes Englisch.

Mixing mysqli mit mysql !!! – Saty

Sie suchen nie nach Fehlern, so dass Sie keine – Jens

Ihre gleiche Abfrage mehrmals ausführen sehen. – JYoThI

Sie haben alles wie mysql, mysqli, mehrere Verbindungen durcheinander gebracht. Verwenden Sie entweder mysql oder mysqli für das gesamte Skript. Es ist nicht nötig, db so viel Zeit zu wählen.

Ihr Code benötigt einige Modifikationen wie $ retval = mysqli_query ($ sql, $ conn); Falsch $ retval = mysqli_query ($ conn, $ sql); Rechts

Hier wird modifizierte Version des Codes:

<?php 
$servername = "localhost"; 
$username = "estgv15592"; 
$password = "estgv155922016";

    /**Not needed. You have already have a active connection */ 
    //mysql_select_db('estgv15592'); 

    $retval = $conn->query($sql); 

    /**An integer greater than zero indicates the number of rows affected or retrieved. Zero indicates that no records were updated for an UPDATE statement, no rows matched the WHERE clause in the query or that no query has yet been executed. -1 indicates that the query returned an error.*/ 
    if(!$retval && $conn->affected_rows != -1) { 
     die('Could not update data: ' . $mysqli->error); 
    } 
    echo "Alterado com Sucesso\n";
