php - 上传图片错误不隐藏即使我上传图片

Question

我在 codeigniter 的后端进行表单验证，在客户端每个字段 alrets 工作正常但在图像字段上错误仍然存​​在，即使我附上图像...下面是我的代码，我附上图像屏幕截图以获取更多详细信息。请在这方面提供帮助。

这是我的 Controller 代码

  public function save(){
    $res = array();
    //form field validation rules
    $this->form_validation->set_rules('titlemaster', 'Main Title', 'required');
    if (!$this->form_validation->run()) {
        echo json_encode(array('mes' => 'text-danger', 'msg' => 'Ourpeople Main Title Required'));
        exit;
    }   
    $this->form_validation->set_rules('detailmaster', 'Main Detail', 'required');
    if (!$this->form_validation->run()) {
        echo json_encode(array('mes' => 'text-danger', 'msg' => 'Oupeople Main Description Required'));
        exit;
    }   
    $config['upload_path'] = 'fassets/images/oupeople';
    $config['allowed_types'] = 'jpg|jpeg|png|gif';
    $config['file_name'] = $_FILES['userfile']['name'];     
    $config['overwrite'] = TRUE;
    //Load upload library and initialize configuration
    $this->load->library('upload', $config);

    $ourpeoplesection = ($this->input->post('name')) . ($this->input->post('desig')) . ($this->input->post('aboutme')) . ($this->input->post('certification')) . ($this->upload->do_upload('userfile'));
    
    if (!empty($ourpeoplesection))
    {   
        $this->form_validation->set_rules('name', 'Name', 'required|max_length[25]');
        if (!$this->form_validation->run()) {
            echo json_encode(array('mes' => 'text-danger', 'msg' => 'Name Required'));
            exit;
        }           
        $this->form_validation->set_rules('desig', 'Designation', 'required|max_length[20]');
        if (!$this->form_validation->run()) {
            echo json_encode(array('mes' => 'text-danger', 'msg' => 'Designation Required'));

        }   
        $this->form_validation->set_rules('aboutme', 'About Employee', 'required'); 
        if (!$this->form_validation->run()) {
            echo json_encode(array('mes' => 'text-danger', 'msg' => 'About Employee Required'));
            exit;
        }       
        $this->form_validation->set_rules('certification', 'Certification', 'required');
        if (!$this->form_validation->run()) {
            echo json_encode(array('mes' => 'text-danger', 'msg' => 'Certification Required'));
            exit;
        }           
        
        if(!$this->upload->do_upload('userfile'))
        {
            $error = 'Please upload Image file. <br>';
            //$error = $this->upload->display_errors('', '<br>');
            echo json_encode(array('mes' => 'alert-danger', 'msg' => $error));
            exit;           
        }

        $userData = array (
            'name' => $this->input->post('name'),
            'desig' => $this->input->post('desig'),

            'google' => $this->input->post('google'),           
            'userfile' =>  $this->upload->data('file_name'),
        );
        
        //Pass user data to model
        $insertData = $this->Ourpeoplemodel->insert($userData);         
    }
    $ourpeopleMaster = array(

    );
    $insertUserData = $this->Ourpeoplemodel->insert_main($ourpeopleMaster);  
        //Storing insertion status message.
    if(($insertUserData && $insertData)){
        $res = array(
            'mes' => 'text-success',
            'msg' => "Record has been saved successfully.",
        );
        echo json_encode($res);
    } else {
        $res = array(
            'mes' => 'text-danger',
            'msg' => "Record not saved",
        );
        echo json_encode($res);
    }      
}   

这里是我的html输入

Answer 1

我想你对我最后的回答感到困惑 - 你可以使用 $_FILES['userfile']['name'] 你只需要将它包装在 isset或者在这种情况下 empty 否则，如果文件未上传，通知将触发(并影响您的 json 响应)。

$config['upload_path'] = 'fassets/images/oupeople';
$config['allowed_types'] = 'jpg|jpeg|png|gif';
//$config['file_name'] = $_FILES['userfile']['name'];     
$config['overwrite'] = TRUE;
//Load upload library and initialize configuration
$this->load->library('upload', $config);

//$ourpeoplesection = ($this->input->post('name')) . ($this->input->post('desig')) . ($this->input->post('aboutme')) . ($this->input->post('certification')) . ($this->upload->do_upload('userfile'));

if (!empty($_FILES['userfile']['name']))
{   
    $this->form_validation->set_rules('name', 'Name', 'required|max_length[25]');
    if (!$this->form_validation->run()) {
        echo json_encode(array('mes' => 'text-danger', 'msg' => 'Name Required'));
        exit;
    }           
    $this->form_validation->set_rules('desig', 'Designation', 'required|max_length[20]');
    if (!$this->form_validation->run()) {
        echo json_encode(array('mes' => 'text-danger', 'msg' => 'Designation Required'));
        exit;
    }   
    $this->form_validation->set_rules('aboutme', 'About Employee', 'required'); 
    if (!$this->form_validation->run()) {
        echo json_encode(array('mes' => 'text-danger', 'msg' => 'About Employee Required'));
        exit;
    }       
    $this->form_validation->set_rules('certification', 'Certification', 'required');
    if (!$this->form_validation->run()) {
        echo json_encode(array('mes' => 'text-danger', 'msg' => 'Certification Required'));
        exit;
    }           

    if(!$this->upload->do_upload('userfile'))
    {
        $error = 'Please upload Image file. <br>';
        //$error = $this->upload->display_errors('', '<br>');
        echo json_encode(array('mes' => 'alert-danger', 'msg' => $error));
        exit;           
    }

    $userData = array (
        'name' => $this->input->post('name'),
        'desig' => $this->input->post('desig'),
        'aboutme' => $this->input->post('aboutme'),
        'certification' => $this->input->post('certification'),
        'facebook' => $this->input->post('facebook'),
        'twitter' => $this->input->post('twitter'),
        'instagram' => $this->input->post('instagram'),
        'google' => $this->input->post('google'),           
        'userfile' =>  $this->upload->data('file_name'),
    );

    //Pass user data to model
    $insertData = $this->Ourpeoplemodel->insert($userData);         
}

我还想建议不要有许多不同的表单验证条件，只有一个...

$this->form_validation->set_rules('name', 'Name', 'required|max_length[25]');
$this->form_validation->set_rules('desig', 'Designation', 'required|max_length[20]');
$this->form_validation->set_rules('aboutme', 'About Employee', 'required'); 
$this->form_validation->set_rules('certification', 'Certification', 'required');
    if (!$this->form_validation->run()) {
        echo json_encode(array('mes' => 'text-danger', 'msg' => validation_errors()));
        exit;
    }
