Mat*_*ins 0 php mysql checkbox select
嗨我有一个页面显示我的表的所有内容.沿着表格的每一行,我还有一个包含复选框的列.当用户通过勾选复选框并按下提交按钮选择一行或多行时,我希望这些行只显示在下一页的表格中(buy.php).我知道它基本上是每行选择的一个select语句.但我不知道如何处理这个问题.有人可以帮忙吗？谢谢

编辑:我尝试了下面的建议,我没有得到一张桌子.只是页面标题出现:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
<title>Confirmation</title>
</head>
<body>
<h1>Order Details</h1>
<?php // Script 12.7 - buy.php
$db = mysql_connect('localhost', '#####', '#####');
mysql_select_db('shopping', $db);
foreach($_POST['buy'] as $item) {
$query = 'SELECT * FROM Items WHERE ID = $item';
if ($r = mysql_query($query, $db)) {
print "<table>";
while ($row = mysql_fetch_array($r)) {
print
"<tr>
<td>{$row['ID']}</td>
<td>{$row['Name']}</td>
<td>{$row['Cost']}</td>
</tr>";
}
print "</table>";
} else {
print '<p style="color: blue">Error!</p>';
}
}
mysql_close($db);
?>
</body>
</html>
您需要创建动态SQL查询.
1)我建议您将复选框更改为以下内容
<input type='checkbox' name='buy[]' value='{$row['ID']}' />
2)遍历所有购买选项
<?php
foreach($_POST['buy'] as $item) {
// Append the ID (in the $item variable) to the SQL query, using WHERE `ID` = $item OR `ID` = $item and so on
}
?>
更新:
<?php // Script 12.7 - buy.php
$db = mysql_connect('localhost', '#####', '#####');
mysql_select_db('shopping', $db);
$query = 'SELECT * FROM Items WHERE ';
$item_count = count($_POST['buy']);
for($i = 0; $i < $item_count; $i++) {
$itemid = (int)mysql_real_escape_string($_POST['buy'][i]); // Secures It
$query .= '`ID` = '.$itemid;
if($i +1 < $item_count) {
$query .= ' OR ';
}
}
if ($r = mysql_query($query, $db)) {
print "<table>";
while ($row = mysql_fetch_array($r)) {
print
"<tr>
<td>{$row['ID']}</td>
<td>{$row['Name']}</td>
<td>{$row['Cost']}</td>
</tr>";
}
print "</table>";
mysql_close($db);
?>
