Question

breaks at my while loop. have been reading the php manual but can’t figure out what im doing wrong here…

$pdo is call to my db connection

function getSelectedPhoto($the_selected_id) {
global $pdo;

$id = $the_selected_id;

$stmt = $pdo->prepare("SELECT handle, src FROM images WHERE id = :id LIMIT 1");
$vars = array(':id' => $id);
$result = $stmt->execute($vars);

if($result) {
    while($row = $result->fetchObject()) {
        echo '<img src="../' . $row->src . '" alt="image" /><br />';
        echo '<p id="handle">' . $row->handle . '</p>';
    } 
} else die("There was some problem");

}

Answer 1

According to the manual “PDOStatement::execute” the execute()-method returns true or false and not the result:

Returns TRUE on success or FALSE on failure.

Of course this will lead to “Call to a member function fetchObject() on a non-object” when calling $result->fetchObject().

Your code should be like this:

$result = $stmt->execute($vars);

if ($result) {
    while( $row = $stmt->fetchObject() ) {}
}
