Bulk action using PHP for mysql entries
We are showing results in a table from a MySQL开发者_运维知识库 database with checkboxes inside it. How can we delete many rows simultaneously if the user ticks 5 rows and clicks the delete button?
HTML:
<form method="post">
<input type="checkbox" name="id[]" value="123" /> Element 1 <br/>
<input type="checkbox" name="id[]" value="5434" /> Element 2 <br/>
<input type="checkbox" name="id[]" value="24" /> Element 3 <br/>
<input type="checkbox" name="id[]" value="76" /> Element 4 <br/>
<input type="submit" value="delete" />
</form>
PHP:
if ( $_SERVER['REQUEST_METHOD'] == 'POST' ) {
$ids = array_walk($_POST['id'], 'intval');
mysql_query('DELETE FROM table WHERE id IN (' . implode(',', $ids) . ')');
}
P.S. I want points !
I won't give you the PHP code, but building an SQL query like this will solve your problem:
DELETE FROM foo WHERE id IN ( … );
See the manual for details.
With PDOStatement like this
$statement = "DELETE FROM table WHERE id = ?";
$conn = new PDO($dns,$user,$pass);
$conn->beginTransaction();
$query = $conn->prepare($statement);
foreach($params as $p){ //$params are your checked id's
$query->bindParam(1,$p);
if($query->execute()){
echo "ok";
}else{
$conn->rollBack();
exit("Error");
}
}
$conn->commit();
