call to a member function execute() on a non-object

Question

My script containing that error is this:

$stmt = $this->db->prepare(\'SELECT libelle,activite,adresse,tel,lat,lng FROM etablissements where type IN (\'         


        

Answer 1

Swap the statement bind and execute and replace result with param, It will work fine

$stmt = $this->db->prepare('SELECT libelle,activite,adresse,tel,lat,lng FROM etablissements 
where type IN ('.$in_list.')');
$stmt->bind_param($libelle,$activite,$adresse,$tel,$lat,$lng);
$stmt->execute();
