PHP5对Mysql5的任意数据库表的管理代码示例（二） - PHP

续：点击添加一个条目就会跳转到add.php //add.php <html><head><title>Add an entry to the database</title><meta http-equiv="Content-Type" content="text/html; charset=gb2312" /></head><body bgcolor=#ffffff><h2>Add an entry</h2><?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);}$id = 0;do{$id++;$query = "select * from $tablename where $colname[0]='$id'";$result = mysql_db_query($database,$query);}while(mysql_fetch_array($result))?><form method="post" action="addsoftware.php"><table width=90% align=center><tr><td><?php echo "$colname[0]";?>:</td><td><?php echo "$id"; ?></td></tr><?for ($col=1;$col<$column;$col++)echo "<tr><td>$colname[$col]:</td><td><input type=text name=$colname[$col] size="100%"></td></tr>";?><input type=hidden name="<?php echo "$colname[0]"; ?>" value="<?php echo "$id"; ?>"><input type=hidden name=tablename value="<?php echo "$tablename"; ?>"><tr><td></td><td><input type=submit value=" Add "></td></tr></table></form><a href="tables.php?tablename=<? echo "$tablename"?>">Finish</a></body></html> 其中id是自动寻找并生成的，而且保证在数据库中id是唯一的。点击add之后会将内容写入数据库，然后会继续让你添加内容，直至添加完毕点击finish回到上一层，显示出添加条目後的数据库内容。下面是添加过程中对数据库进行操作的addsoftware.php //addsoftware.php <?php$database = "sunsite";$tablename = $_POST['tablename'];mysql_connect("localhost","root","") or die ("Problem connecting to DataBase");$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);}
for($col=0;$col<$column;$col++)$para[$col] = $_POST[$colname[$col]];
if ($_POST['name']){mysql_connect("localhost","root","") or die ("Problem connecting to DataBase");$query = "insert into $tablename values ('$para[0]' ";for($col=1;$col<$column;$col++)$query = $query . ",'" . $para[$col] . "'"; $query = $query . ");";
$result = mysql_db_query($database, $query);Header("Location: add.php?tablename=$tablename");}else{echo "No name Entered. Please go back and reenter name";} ?><meta http-equiv="Content-Type" content="text/html; charset=gb2312" />待续。
