Answer 1

首次验证表格
然后上传

<form method="post" name="testForm" ng-controller="ExampleController" action="test.place">
  <input ng-model="val" name="anim"  />
         <button>submit</button>
</form>

像这样（就像我在评论中提到的那样）

if( false != ($valid = $this->form_validation->run()) && $this->upload->do_upload('product_image')){
    $uploaddata  = $this->upload->data();
    $product_image=$uploaddata['file_name'];
    // $this->db->insert('product',array('product_image'=>$this->upload->file_name));
    $data = $this->input->post();
    unset($data['submit']);
    $this->load->model('queries_product');  
    if($this->queries_product->insert_product($data)){
        $this->session->set_flashdata('msg','Successfully Inserted');
    }else{
        $this->session->set_flashdata('msg','Failed to Insert');
    }
    return redirect('inventory');
}else{
    if(!$valid)
       echo validation_errors();
    else
       $this->session->set_flashdata('msg','Failed to Upload');
}

通过在if条件中分配false != ( $valid = ...)，我们可以检查哪一个实际上失败了，而没有做任何其他实际工作。

正如我在评论中提到的，if中参数的顺序很重要。如果先完成validation并返回false，PHP已经知道条件不会成功。那是因为&&要求双方都是true，如果一方是false，则不需要检查另一方，因此PHP会立即进入块中的下一个条件（这种情况下的else）没有上传。
