two sets which the names are engine1 and engine2. i wanted to insert them in my database using implode with this code..

$_POST['engine1'] = array();
    $_POST['engine2'] = array();

    $engine1 = implode(',', $_POST['engine1']);
    $engine2 = implode(',', $_POST['engine2']);

but everytime i check my database table, the columns are empty. what part do you think am i doing it wrong?? please help!

Why are you initializing $_POST['engine1'] = array(); $_POST['engine2'] = array(); — Happy Coding

You are declaring $_POST['engine1'] as an empty array, overwriting it if it exists. Remove the following lines:

$_POST['engine1'] = array();
$_POST['engine2'] = array();

so that $_POST['engine1'] comes from the POSTED form values.

Remove these lines :

$_POST['engine1'] = array();
$_POST['engine2'] = array();

Only use:

$engine1 = implode(',', $_POST['engine1']);
$engine2 = implode(',', $_POST['engine2']);
