【问题描述】：

我想在CodeIgniter中添加一个上传图片字段来注册一个表单。

我在控制器中的注册码：

function add_new_ticket() 

    if ($this->input->post('fullname', TRUE)
        && $this->input->post('nID', TRUE)
        && $this->input->post('age', TRUE)
        && $this->input->post('gender', TRUE)
        // && $this->input->post('isFileID', TRUE)
        // && $this->input->post('FileID', TRUE)
        && $this->input->post('phone', TRUE)
        && $this->input->post('type', TRUE)
        && $this->input->post('opsType', TRUE)
        && $this->input->post('clienc', TRUE)
        && $this->input->post('dr', TRUE)
        && strlen($this->input->post('phone', TRUE)) >= 9
        && strlen($this->input->post('nID', TRUE)) >= 9
        && (int) $this->input->post('age', TRUE) <= 99
        && count(explode('-',$this->input->post('default-date', TRUE)) > 1)
    )

还有我在模型文件中的代码：

<?php
    class user extends CI_Model 

        public function add() 
            $data = array(
                'name' => $this->input->post('name'),
                'password' => $this->input->post('password'),
                'add_date' => time(),
                'email' => $this->input->post('email'),
                'birth_date' => $this->input->post('birth'),
                'phone' => $this->input->post('phone'),
                'mobile' => $this->input->post('mobile'),
                'sex' => $this->input->post('type'),
                'city' => $this->input->post('city'),
                'first_name' => $this->input->post('first_name'),
                'last_name' => $this->input->post('last_name'),
                'main_street' => $this->input->post('main_street'),
                'sub_street' => $this->input->post('sub_street'),
                'type' => $this->input->post('member_type'),
                'delegate_name' => $this->input->post('delegate_name'),
                'delegate_email' => $this->input->post('delegate_email'),
                'delegate_pass' => md5($this->input->post('delegate_pass')),
                'location' => serialize(array($this->input->post('lat'), $this->input->post('lng')))
            );
            $this->db->insert('admins', $data);
        

        public function edit($id = FALSE) 

            $this->db->set('name', $this->input->post('name'));

            $this->db->set('email', $this->input->post('email'));
            $this->db->set('phone', $this->input->post('phone'));
            $this->db->set('mobile', $this->input->post('mobile'));
            $this->db->set('birth_date', $this->input->post('birth'));

            $this->db->set('first_name', $this->input->post('first_name'));
            $this->db->set('last_name', $this->input->post('last_name'));

            $this->db->set('city', $this->input->post('city'));

            $this->db->set('main_street', $this->input->post('main_street'));

            $this->db->set('sub_street', $this->input->post('sub_street'));

            if ($this->input->post('type')) 
                $this->db->set('sex', $this->input->post('type'));
            

            if ($this->input->post('lat') and $this->input->post('lng')) 
                $this->db->set('location', serialize(array($this->input->post('lat'), $this->input->post('lng'))));
            

            if ($this->input->post('password') !== '') 
                $this->db->set('password', md5($this->input->post('password')));
            

            $this->db->where('id', $id);
            $this->db->update('admins');
        

        public function del($id = FALSE) 
            $this->db->where('id', $id);
            $this->db->delete('admins');
        
    

我想添加一个允许上传图片的字段。

【问题讨论】：

你看过codeigniter文件上传codeigniter.com/user_guide/libraries/file_uploading.html

是的，我做到了，但你不明白我想将此选项插入注册表单中

你到底想要什么你想知道如何上传图片吗？？

【参考方案1】：

我假设您想在表单中添加“图片上传”选项

public function add() 



/* Configuration array various settings

  can be set here

  **/
 $config['upload_path'] = '/file_path/'; // path where image will be saved
         $config['allowed_types'] = 'gif|jpg|png|jpeg';
         $this->load->library('upload', $config);
         $this->upload->do_upload('image');
         $data_upload_files = $this->upload->data();

         $image = $data_upload_files[full_path];
$data = array(
        'name' => $this->input->post('name'),
        'password' => $this->input->post('password'),
        'add_date' => time(),
        'email' => $this->input->post('email'),
        'birth_date' => $this->input->post('birth'),
        'phone' => $this->input->post('phone'),
        'mobile' => $this->input->post('mobile'),
        'sex' => $this->input->post('type'),
        'city' => $this->input->post('city'),
        'first_name' => $this->input->post('first_name'),
        'last_name' => $this->input->post('last_name'),
        'main_street' => $this->input->post('main_street'),
        'sub_street' => $this->input->post('sub_street'),
        'type' => $this->input->post('member_type'),
        'delegate_name' => $this->input->post('delegate_name'),
        'delegate_email' => $this->input->post('delegate_email'),
        'delegate_pass' => md5($this->input->post('delegate_pass')),
        'location' => serialize(array($this->input->post('lat'), $this->input->post('lng')))
        'image'=>$image; // add this for image

    );
 $this->db->insert('admins', $data);

View 有这样的东西

<input type="file" name="image" size="20" />

控制器

function add_new_ticket() 

    if ($this->input->post('fullname', TRUE) 
        && $this->input->post('nID', TRUE) 
        && $this->input->post('age', TRUE)
        && $this->input->post('gender', TRUE) 
        // && $this->input->post('isFileID', TRUE)
        // && $this->input->post('FileID', TRUE)
        && $this->input->post('phone', TRUE)
        && $this->input->post('type', TRUE)
        && $this->input->post('opsType', TRUE)
        && $this->input->post('clienc', TRUE)
        && $this->input->post('dr', TRUE)
        && strlen($this->input->post('phone', TRUE)) >= 9
        && strlen($this->input->post('nID', TRUE)) >= 9
        && (int) $this->input->post('age', TRUE) <= 99
        && $this->upload->do_upload() // add something like this              
&& count(explode('-',$this->input->post('default-date', TRUE)) > 1)
            )

注意：

输入名称必须在$this->upload->do_upload('image')中定义相同；即名称="图像"

输入元素必须有多个=“多个”或只有多个

3.$this->load->library('upload'); //加载库

4.回调，$this->upload->do_upload() 会将给定字段名称中选择的文件上传到目标文件夹。

5.回调 $this->upload->data() 返回一个与上传文件相关的数据数组，如文件名、路径、大小等。

【讨论】：

谢谢你帮助我，但我希望你能简单地解释一下，因为我不明白，我应该把哪些代码放在（控制器、模型、视图）文件夹中

你好，我尝试这样做，但没有图像上传我的 sql 数据库中是否有任何修改，例如添加表或做任何事情

我没有看到任何错误，但我在“上传”目录中看不到图像，尽管我获得了 777 权限

@ahmed 在模型中的 $this->db->insert('admins', $data); 之前添加 die(var_dump($data)); 并显示结果

我这样做了，但是当我填写了所有信息然后按下按钮时，它似乎冻结没有任何变化

【参考方案2】：

上传的时候做if语句

if(isset($_FILES['userfile']) && !empty($_FILES['userfile']['name']) && $this->form_validation->run() != FALSE)
            

                $profile = array(

                    'mname' => $this->input->post('mname'), 
                    'lname' => $this->input->post('lname'),
                    'dob' => date('Y-m-d',strtotime($this->input->post('dob'))),
                    'address' => $this->input->post('address'),
