PHP5对Mysql5的任意数据库表的管理代码示例（四） - PHP

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。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。
