我正在使用 Dreamweaver 并在一个页面上有两个表单，每个表单都使用 php 提交到同一个 mySQL 数据库，但行不同。它们每个都有“粘性”代码以防止它们在我将数据提交到 mySQL 时丢失值.问题是当我提交 form2 时 form1 丢失了值，反之亦然。整整两天让我发疯。 提前致谢。
<?php require_once('Connections/pmpConn.php'); ?>
<?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "")
{
if (PHP_VERSION < 6) {
$theValue = get_magic_quotes_gpc() ? stripslashes($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;
case "long":
case "int":
$theValue = ($theValue != "") ? intval($theValue) : "NULL";
break;
case "double":
$theValue = ($theValue != "") ? doubleval($theValue) : "NULL";
break;
case "date":
$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;
case "defined":
$theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
break;
}
return $theValue;
}
}
$editFormAction = $_SERVER['PHP_SELF'];
if (isset($_SERVER['QUERY_STRING'])) {
$editFormAction .= "?" . htmlentities($_SERVER['QUERY_STRING']);
}
if ((isset($_POST["MM_update"])) && ($_POST["MM_update"] == "form2")) {
$updateSQL = sprintf("UPDATE readiness_one_day SET on_time=%s WHERE ready_primary=%s",
GetSQLValueString(isset($_POST['on_time2']) ? "true" : "", "defined","1","0"),
GetSQLValueString($_POST['ready_primary2'], "int"));
mysql_select_db($database_pmpConn, $pmpConn);
$Result1 = mysql_query($updateSQL, $pmpConn) or die(mysql_error());
}
if ((isset($_POST["MM_update"])) && ($_POST["MM_update"] == "form1")) {
$updateSQL = sprintf("UPDATE readiness_one_day SET on_time=%s WHERE ready_primary=%s",
GetSQLValueString(isset($_POST['on_time1']) ? "true" : "", "defined","1","0"),
GetSQLValueString($_POST['ready_primary1'], "int"));
mysql_select_db($database_pmpConn, $pmpConn);
$Result1 = mysql_query($updateSQL, $pmpConn) or die(mysql_error());
}
?>

最佳答案
您应该在每个表单提交后立即设置 $_SESSION 变量，这样您就可以在页面之间保留值。之后，您可以执行以下操作:
在表单提交页面上:
<?php
session_start();
$SESSION['one_box'] = True;
?>
在带有表单的页面上:
<?php
start_session();
function selected($value) {
if (isset($_SESSION[$value]) {
return "checked='yes'";
}
else {
return "";
}
?>
<input type="checkbox" name="one_box" <?php echo selected("one_box"); ?> />
