续假如点击删除一个条目则会跳转到del.php
//del.php
%26lt;html%26gt;
%26lt;head%26gt;%26lt;title%26gt;Deleting an entry from the database%26lt;/title%26gt;
%26lt;meta http-equiv="Content-Type" content="text/html; charset=gb2312" /%26gt;
%26lt;/head%26gt;
%26lt;body bgcolor=#ffffff%26gt;
%26lt;h2%26gt;Delete an entry%26lt;/h2%26gt;
%26lt;?
$database = "sunsite";
$tablename = $_REQUEST['tablename'];
echo "%26lt;h2%26gt;Data from $tablename%26lt;/h2%26gt;";
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:%26lt;br%26gt;%26lt;p%26gt;%26lt;/p%26gt;";
echo "%26lt;table width=90% align=center border=1%26gt;%26lt;tr%26gt;";
while ($r = mysql_fetch_array($result))
{
echo "%26lt;td align=center bgcolor=#00FFFF%26gt;$r[0]%26lt;/td%26gt;";
$colname[$column] = $r[0];
$column = $column + 1;
}
echo "%26lt;/tr%26gt;";
mysql_free_result($result);
$query = "select * from $tablename";
$result = mysql_db_query($database, $query);
if ($result)
while ($r = mysql_fetch_array($result))
{
echo "%26lt;tr%26gt;";
echo "%26lt;td%26gt;%26lt;a href="dele.php?$colname[0]=$r[0]%26amp;tablename=$tablename"%26gt;$r[0]%26lt;/td%26gt;";
for($col=1;$col%26lt;$column;$col++) echo "%26lt;td%26gt;$r[$col]%26lt;/td%26gt;";
echo "%26lt;/tr%26gt;";
}
echo "%26lt;/table%26gt;";
}
else echo "No data.";
mysql_free_result($result);
?%26gt;
%26lt;a href="tables.php?tablename=%26lt;? echo "$tablename"?%26gt;"%26gt;Finish%26lt;/a%26gt;
%26lt;/body%26gt;
%26lt;/html%26gt;
然后写入数据库
//dele.php
%26lt;?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");
?%26gt;
%26lt;meta http-equiv="Content-Type" content="text/html; charset=gb2312" /%26gt;
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。
注重提醒！以上代码在copy的时候一定注重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。
