私は Dreamweaver でプロジェクトを行っていますが、select ステートメントで問題が発生しました。私はこれを持っています
SELECT *
FROM client, `statement`
WHERE client.client_id = `statement`.client_id
これを実行すると、データベース内の全員が選択されます。そこで、このクエリに別の WHERE ステートメントを追加したいと思います。今回は、client.username をセッション変数「MM_Username」と比較します。
だから私はこのようなものを見ています
SELECT *
FROM client, `statement`
WHERE client.client_id = `statement`.client_id AND WHERE client.username = '$_SESSION['MM_Username']'
セッション PHP コードは次のとおりです。
<?php
if (!isset($_SESSION)) {
session_start();
}
$MM_authorizedUsers = "";
$MM_donotCheckaccess = "true";
// *** Restrict Access To Page: Grant or deny access to this page
function isAuthorized($strUsers, $strGroups, $UserName, $UserGroup) {
// For security, start by assuming the visitor is NOT authorized.
$isValid = False;
// When a visitor has logged into this site, the Session variable MM_Username set equal to their username.
// Therefore, we know that a user is NOT logged in if that Session variable is blank.
if (!empty($UserName)) {
// Besides being logged in, you may restrict access to only certain users based on an ID established when they login.
// Parse the strings into arrays.
$arrUsers = Explode(",", $strUsers);
$arrGroups = Explode(",", $strGroups);
if (in_array($UserName, $arrUsers)) {
$isValid = true;
}
// Or, you may restrict access to only certain users based on their username.
if (in_array($UserGroup, $arrGroups)) {
$isValid = true;
}
if (($strUsers == "") && true) {
$isValid = true;
}
}
return $isValid;
}
$MM_restrictGoTo = "myflog.php";
if (!((isset($_SESSION['MM_Username'])) && (isAuthorized("",$MM_authorizedUsers, $_SESSION['MM_Username'], $_SESSION['MM_UserGroup'])))) {
$MM_qsChar = "?";
$MM_referrer = $_SERVER['PHP_SELF'];
if (strpos($MM_restrictGoTo, "?")) $MM_qsChar = "&";
if (isset($_SERVER['QUERY_STRING']) && strlen($_SERVER['QUERY_STRING']) > 0)
$MM_referrer .= "?" . $_SERVER['QUERY_STRING'];
$MM_restrictGoTo = $MM_restrictGoTo. $MM_qsChar . "accesscheck=" . urlencode($MM_referrer);
header("Location: ". $MM_restrictGoTo);
exit;
}
?>
