The Activity image field is required in CodeIgniter - codeigniter-3

Question

I'm trying to upload image in my code project. In the image field I'm getting
"The Activity image field is required."
The below code is my Activity_controller
public function create_activity(){
//...Upload the image
//... path to upload image
$config['upload_path'] = './assets/images/uploads'; // The path to upload the image
$config['allowed_types'] = 'gif|jpg|jpeg|png|pdf|doc';
$config['max_size'] = '2048';
$config['max_width'] = '500';
$config['max_height'] = '500';
$this->load->library('upload',$config);
if(!$this->upload->do_upload()) {
$error = array('error' => $this->upload->display_errors());
$activity_image = 'noimage.jpg';
} else {
$data = array('upload_data' => $this->upload->data());
$activity_image = $_FILES['userfile']['name'];
}
$this->activity_model->save_activity($activity_image);
redirect('activity_controller');
}
Activity model, insert activity in the database Here is only the function to insert data in the database.
public function save_activity($activity_image){
//... code to insert others data in the database
'activity_image' => $activity_image
);
return $this->db->insert('activity', $data);
}
Below code is create_activities.php file in the view folder:
<?php echo validation_errors(); ?>
<?php echo form_open_multipart('activity_controller/create_activity'); ?>
<div class="form-group">
<label>Upload image</label>
<input name="userfile" type="file">
</div>
I have loaded the model in the autoload.php file.
I also used <input name="activity_image type="file">
"image_name" is the name of the field in the database table
Please someone can help me to solve this problem? I will appreciate your help
Thank you in advance

I think you forgot to add (enctype="multipart/form-data") in your view file in form Tag.
Here, Usen this code. I hope this one is help full to you.
<form action="/action_page_binary.asp" method="post" enctype="multipart/form-data">
First name: <input type="file" name="name"><br>
<input type="submit" value="Submit">
</form>
