PHP5对Mysql5的任意数据库表的管理代码示例之四

如果点击删除一个条目则会跳转到del.php
//del.php

Delete an entry

$database = "sunsite";
$tablename = $_REQUEST['tablename'];
echo "

Data from $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)
{
echo "Found these entries in the database:

";
echo "";
while ($r = mysql_fetch_array($result))
{
echo "";
$colname[$column] = $r[0];
$column = $column + 1;
}
echo "";
mysql_free_result($result);

$query = "select * from $tablename";
$result = mysql_db_query($database, $query);
if ($result)
while ($r = mysql_fetch_array($result))
{
echo "

";
echo "";
for($col=1;$col<$column;$col++) echo "";
echo "";
}
echo "

$r[0]
$r[0]	$r[$col]

";
}
else echo "No data.";
mysql_free_result($result);

?>
">Finish

 
然后写入数据库
//dele.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");
?>

以上就是所有的了。
把它们都放到同一个目录下面即可。
注意：提醒！以上代码在copy的时候一定注意在编辑器里面把每一行代码前面的tab去掉，不然php5编译不过。
而且在每个文件中$database目前为sunsite，$table为software，这个可以根据需要修改。
