Answer 1

您的模型似乎存在命名问题。文件名与文件内的类匹配得很多。您也没有遵循CodeIgniter的文件命名约定。

模型文件preDemo.php应该命名为Pre_demo.php，并且可以像这样声明

class Pre_demo extends Model {

完成后，模型应该成功加载（显然不会在代码中加载）。

$this->load->model('prerecorded/pre_demo');
$this->pre_demo->preDemo1($data);

Answer 2

正确的模型加载函数：

$this->prerecorded_preDemo->preDemo1($data);

如何在opencart 3.0中加载模型？
