我正在创建一个在线游戏,但在更新数据库中的某些字段时遇到问题。这是表单和php代码。
<form method='post'>
<div style="float: left; width: 630px; color: white;">
<div style="float: left; width: 400px; background: #555; height: 20px;">
<?php
if ($row['Protected'] == 1)
{
?>
<img src="images/pass.png"></img>
<input type="password" name="pass" placeholder="Password" style="height: 18px;" />
<?php
}
echo("<input type='submit' name='enter' style='background: #555; text-decoration: underline;' value='$row[Name]' />");
?>
</div>
<div style="float: right; width: 229px; background: #555; margin-left: 1px; height: 20px;">
<?php
echo($row['NrPlayers']);
echo("/");
echo($row['MaxPlayers']);
echo(" Players");
?>
</div>
<div style="clear: both;">
<?php
echo($row['Descr']);
?>
</div>
<div style="background: #ccc; font-size: 13px; margin-bottom: 2px; color: black;">
<?php
echo($row['FName']);
echo(" ");
echo($row['LName']);
?>
</div>
<input type="hidden" name="id" value="<?php$row['Id_Room']?>" />
<input type="hidden" name="protect" value="<?php$row['Protected']?>" />
<input type="hidden" name="password" value="<?php$row['Pass']?>" />
<input type="hidden" name="nr" value="<?php$row['NrPlayers']?>" />
</div>
</form>
<?php
if (isset($_POST['enter']))
{
if ($_POST['protect'] == 1)
{
if ($_POST['pass'] == $_POST['password'])
{
$nr = $_POST['nr'] + 1;
mysql_query("upadte users set Id_Room = '$_POST[id]' where Id_User = '$_SESSION[id]'");
mysql_query("update rooms set NrPlayers = '$nr' where Id_Room = '$_POST[id]'");
header("Location: game.php");
}
else
{
?>
<span style="color: red; text-align: center;">The password you entered is incorrect.</span>
<?php
}
}
else
if (($_POST['protect'] == 0))
{*/
$nr = $_POST['nr'] + 1;
mysql_query("upadte users set Id_Room = '$_POST[id]' where Id_User = '$_SESSION[id]'");
mysql_query("update rooms set NrPlayers = '$nr' where Id_Room = '$_POST[id]'");
header("Location: game.php");
}
}
?>
有两个更新和一个重定向。因此,更新不起作用,但重定向起作用。
