Как мультизагрузить изображения в Codeigniter

Question

Я пытаюсь сделать несколько загрузок фотографий в форму в Codeigniter 3. Когда я хочу загрузить фотографии, нажатие кнопки «Upload» отправляет мне всю форму и добавляет только одну фотографию. Если бы кто-нибудь мог дать мне советы, как это сделать, я был бы благодарен. Я мог бы сделать это как две отдельные формы, но тогда это не сработало бы так, как мне хотелось бы.

Мой вид формы

<form method='post' action='<?php echo base_url();?>ads/create' enctype='multipart/form-data'>

Answer 1

в этом примере вы загружаете одно изображение и несколько изображений в разные папки.

if ($ param == "upload") {

    $config['upload_path']          = './uploads/user_profil/';
    $config['allowed_types']        = 'gif|jpg|png';

    $config['file_name']             = $this->input->post('user_profile')."_profil_image_".mt_rand(100000,900000);

        $this->load->library('upload', $config, 'user_profile'); // Create custom object for cover upload
        $this->user_profile->initialize($config);


        if ( !empty($this->user_profile->do_upload('user_profil_image') ) )

            $upload_data = $this->user_profile->data(); 
            $file_name_profile_picture = $upload_data['file_name'];

        else

            $data_update_qr_status = array(

            $this->db->where('profile_qr_id', $this->input->post('profile_qr_id'));

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

// ridirect      
 redirect(base_url('admin/uploads_view'), 'refresh');        

}

Answer 2

Вы должны изменить

if($this->upload->do_upload('file')){ 

на

if($this->upload->do_upload('files')){
