私のウェブサイトの登録ページに、新しいアカウントをデータベースに登録するときに、テーブル名が正しくありませんというエラーメッセージが表示されます。次のようにPHP/SQLで無効なテーブル名エラー
私のコードは次のとおりです。
<?php require_once('Connections/localhost.php'); ?>
<?php

$theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;
}
$theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);
switch ($theType) {
case "text":
$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;

はあなたがすべて大歓迎されている私のコードをデバッグしようとしていただきありがとうございます。あなたは大きな問題を抱えている：
コードをデバッグするには、SQLステートメントとしてデータベースに送信される前に、 '$ insertSQL'文字列の値を出力します。 （ロギング機能を持たない場合は、単に 'echo'や' vardump'を使います。）SQL文の問題を見つけたら、コードを修正することができます。 （btw ... StackOverflowはデバッグサービスではありません。https://ericlippert.com/2014/03/05/how-to-debug-small-programs/） – spencer7593
ありがとう、私は確信しています将来それを使用する！ –
