sprintf(): Too few arguments... why??
you have % in one of the variables!
?
example:
$Consulta = sprintf ("UPDATE info_table SET title = '%s, alt = '%s', abstract = '%s', WHERE ref = '%s';", $title, $alt, $abstract, $ref);???? //error
?
$Consulta = sprintf ("UPDATE info_table SET title = '%s', alt = '%s', abstract = '%s', WHERE ref = '%s';", $title, $alt, $abstract, $ref);???? //right
