Call to a member function fetch()
Ik heb een script gedownload ergens waar volgende code in staat:
Code (php)
1

<?php
function dbRow($query) {
$q = dbQuery($query);
return $q->fetch(PDO::FETCH_ASSOC);
}
?>
function dbRow($query) {
$q = dbQuery($query);
return $q->fetch(PDO::FETCH_ASSOC);
}
?>
wanneer ik het script nu uitvoer, krijg ik de volgende error:
Code (php)
1
Fatal error: Call to a member function fetch() on a non-object in blahblahblah
Ik heb al op google gezocht of ik ergens een of ik ergens een oplossing kan vinden, maar deze vind ik niet.
Hebben jullie misschien een oplossing om dit te verhelpen?
Mvg Jules
Een functie maken voor iets wat al bestaat slaat natuurlijk nergens op.

Al de functies die daarin gedeclareerd worden heb je al tot je beschikking met PDO.
