所有查询都成功执行,当我检查MySQL行中的表时,插入成功且没有任何错误,但lastInsertId()
返回 0。为什么?
我的代码:
// queries executes successfully, but lastInsetId() returns 0
// the menus table has `id` column with primary auto_increment index
// why lastInsertId return 0 and doesn't return actual id?
$insertMenuQuery = "
SELECT @rght:=`rght`+2,@lft:=`rght`+1 FROM `menus` ORDER BY `rght` DESC limit 1;
INSERT INTO `menus`(`parent_id`, `title`, `options`, `lang`, `lft`, `rght`)
values
(:parent_id, :title, :options, :lang, @lft, @rght);";
try {
// menu sql query
$dbSmt = $db->prepare($insertMenuQuery);
// execute sql query
$dbSmt->execute($arrayOfParameterOfMenu);
// menu id
$menuId = $db->lastInsertId();
// return
return $menuId;
} catch (Exception $e) {
throw new ForbiddenException('Database error.' . $e->getMessage());
}
