Salve. Uno script che ho fatto mi dà questo errore. Non mi è mai capitato e quindi non ho la minima idea di come risolvere il problema. Vi posto la query:

Codice PHP:
$query "INSERT INTO `catalog_products` 
                                              ( name ,
                                                material ,
                                                price,
                                                discount,
                                                availability,
                                                parent,
                                                brand,
                                                description,
                                                target )
                                       VALUES ( '" 
$this->fields['name']->val "' ,
                                                '" 
$this->fields['material']->val "' ,
                                                '" 
$this->fields['price']->val "' ,
                                                '" 
$this->fields['discount']->val "' ,
                                                '" 
$this->fields['availability']->val "' ,
                                                '" 
$this->fields['parent']->val "' ,
                                                '" 
$this->fields['brand']->val "' ,
                                                '" 
$this->fields['description']->val "'
                                                '" 
$this->fields['target']->val "' )"
