Question

I have 12 different id’s I want to compare to $_GET. Right now I’m pulling all my id’s like this:

$sth = $dbh->query('SELECT DISTINCT courseId from training');  
$sth->setFetchMode(PDO::FETCH_ASSOC); 
    while($row = $sth->fetch('courseId')) {
        print_r($row['courseId'] . ',');
    }

This returns:

8,5,9,10,12,7,4,3,2,6,11,1, 

Now, I want to check the id’s against $_GET['courseId']

How do I write an if statement to compare the values of $row['courseId'] and $_GET['courseId']. I want to do something like:

if($_GET['courseId'] == $row['1']) {
    //Do something here
} elseif ($_GET['courseId'] == $row['2']) {
    //Do something different
}

Hopefully that makes sense. Thanks!

Replace your print_r line with:

if( $row['courseId'] == $_GET['courseId']) break;

Then, after the loop:

if( !$row) echo "ERROR: Course ID not found";
else {
    // do stuff with the $row here.
}
