php - 使用 CodeIgniter 将上传图片字段添加到注册表单

Question

我想在 CodeIgniter 中添加上传图片字段以注册表单.

我在 Controller 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。

Answer 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" />

Controller

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:

输入名称必须与 $this->upload->do_upload('image') 中定义的相同；即 name="image"

输入元素必须有 multiple="multiple"或只是 multiple

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

4.回调，$this->upload->do_upload() 会将在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() 返回与上传文件相关的数据数组，如文件名、路径、大小等。
