Delete an entry

">Finish


Then write to the database
//dele.php(as now The mainstream development language)
(as the current mainstream development language)
$database = "sunsite";
$tablename = $_GET[tablename ];
MySQL(The best combination with PHP)_connect("localhost","root","") or die ("Problem connecting to DataBase");
$query = "show columns from $tablename";
$result = MySQL(The best combination with PHP)_db_query($database,$query);
$column = 0;
if ($result)
{
while ($r = MySQL(The best combination with PHP)_fetch_array($result))
{
$colname[ $column] = $r[0];
$column = $column + 1;
}
MySQL(The best combination with PHP)_free_result($result);
}

$para = $_GET[$colname[0]];

MySQL(The best combination with PHP)_connect("localhost" ,"root","") or die ("Problem connecting to DataBase");
$query = "delete from $tablename where $colname[0]=$para;";
$result = MySQL(The best combination with PHP)_db_query($database, $query);
Header("Location: edit.php(as the current mainstream development language)? tablename=$tablename");
?>

The above is all the code .
Just put them all in the same directory.
Attention: Reminder! When copying the above code, be sure to remove the tab in front of each line of code in the editor, otherwise php(as the current mainstream development language)5 will not compile.
And in each file, $database is currently sunsite and $table is software. This can be modified as needed.

Feedback is welcome.
