续：如果点击删除一个条目则会跳转到del.php
//del.php
<html>
<head><title>Deleting an entry from the database</title>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
</head>
<body bgcolor=#ffffff>
<h2>Delete an entry</h2>
<?
$database = "sunsite";
$tablename = $_REQUEST['tablename'];
echo "<h2>Data from $tablename</h2>";
mysql_connect("localhost","root","") or die ("Problem connecting to DataBase");
$query = "show columns from $tablename";
$result = mysql_db_query($database,$query);
$column = 0;
if ($result)
{
echo "Found these entries in the database:<br><p></p>";
echo "<table width=90% align=center border=1><tr>";
while ($r = mysql_fetch_array($result))
{
echo "<td align=center bgcolor=#00FFFF>$r[0]</td>";
$colname[$column] = $r[0];
$column = $column + 1;
}
echo "</tr>";
mysql_free_result($result);
$query = "select * from $tablename";
$result = mysql_db_query($database, $query);
if ($result)
while ($r = mysql_fetch_array($result))
{
echo "<tr>";
echo "<td><a href="dele.php?$colname[0]=$r[0]&tablename=$tablename">$r[0]</td>";
for($col=1;$col<$column;$col++) echo "<td>$r[$col]</td>";
echo "</tr>";
}
echo "</table>";
}
else echo "No data.";
mysql_free_result($result);
?>
<a href="tables.php?tablename=<? echo "$tablename"?>">Finish</a>
</body>
</html>
然后写入数据库
//dele.php
<?php
$database = "sunsite";
$tablename = $_GET['tablename'];
mysql_connect("localhost","root","") or die ("Problem connecting to DataBase");
$query = "show columns from $tablename";
$result = mysql_db_query($database,$query);
$column = 0;
if ($result)
{
while ($r = mysql_fetch_array($result))
{
$colname[$column] = $r[0];
$column = $column + 1;
}
mysql_free_result($result);
}
$para = $_GET[$colname[0]];
mysql_connect("localhost","root","") or die ("Problem connecting to DataBase");
$query = "delete from $tablename where $colname[0]='$para';";
$result = mysql_db_query($database, $query);
Header("Location: edit.php?tablename=$tablename");
?>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
以上就是所有的代码了。
把它们都放到同一个目录下面即可。
