PHP5对Mysql5的任意数据库表的管理代码示例（四）
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='https://www.haobala.com/bcjs/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($result);
?><a href='https://www.haobala.com/bcjs/tables.php?tablename=<? echo '$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。
