通过查询删除PHP中的Access数据库

Question

So basically, i'm working on this exercise for PHP and i'm not exactly the brightest on that topic yet.
I have to create a query that deletes the records of the database and i have no idea how.
My code is:

<?php

$dbName='REIZEN.mdb';

$db = new PDO("odbc:DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=".      realpath($dbName) ."; Uid=; Pwd=;");

$result = $db->query("SELECT * FROM klanten");

echo ('<table border = "1" style="width=100%">');

foreach ($result as $value){

    echo ('<tr>');

    echo ('<td>');
echo ($value['KLANTNR']);
    echo ('</td>');

    echo ('<td>');
echo ($value['VOORNAAM']);
    echo ('</td>');

    echo ('<td>');
echo ($value['ACHTERNAAM']);
    echo ('</td>');

    echo ('<td>');
echo ($value['ADRES']);
    echo ('</td>');

    echo ('<td>');
echo ($value['POSTCODE']);
    echo ('</td>');

    echo ('<td>');
echo ($value['WOONPLAATS']);
    echo ('</td>');

    echo ('<td>');
echo ($value['PROVINCIE']);
    echo ('</td>');

    echo ('<td>');
echo ($value['TELEFOON']);
    echo ('</td>');
    echo ('</tr>');

}

echo ('</table>');

?>

how would I be able to send a variable to another page using this format?

Answer 1

SELECT * FROM klanten选择表中的所有条目， DELETE * FROM klanten将其删除， DELETE FROM klanten WHERE id = 1将仅删除DELETE FROM klanten WHERE id = 1的条目

Answer 2

If you have primary key name is id in your table then first you can create delete page link in your html. like below code.

 echo ('<td>');
    $path = "delete.php"
    echo ('<a href="'. $path.'?id='.$value['ID'].'">Delete</a>');
    echo ('</td>');

And then in delete.php page you can write code like below.

if(isset($_GET['id']))
    {
        $id = $_GET['id'];
        $dbName='REIZEN.mdb';
        $db = new PDO("odbc:DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=".      realpath($dbName) ."; Uid=; Pwd=;");
        $result = $db->query("DELETE FROM klanten WHERE id = $id");
        if($result)
        {
            header('Location: http://www.example.com/index.php');
        }
    }

i hope this will helpful for you.
