Why can't I delete the selected data?

What's wrong?

        
  
   prepare("delete from class where name=?");        $stmt2->execute(array($_POST['name']));        }    ?>

Your code is rather strange to write.
First say why can't delete:
The box for your input does not have the Value property. So your $_post[' name ' doesn't get a value.
You can change it into

echo ''.$v['name'].'';

Then I look at your code, do you want to do a long choice to delete it? Then you need post to submit an array to PHP, then you can modify the Name property of input:

echo ''.$v['name'].'';

Then the post that was received with PHP is this:

$name = $_POST['name'];//array(name1,name2....)

At this point you need to deal with this $name. Change your SQL statement to

delete from class where name in (name1,name2,name3...)

such as the following:

$sql = "delete from class where name in (" . trim(str_repeat('?,',count($name)),',') . ")";$stmt2 = $pdo->prepare($sql);$stmt2->execute($name);

Then, your judgment Is_post code is best in the output list before, otherwise, first give you output, after deletion, see no effect.

Is this just getting started?
