codeigniter can't upload picture to folder - php

Question

I need help to upload picture in folder. Here's the thing, I have tested before and it worked. After a while I test this again and boom it doesn't work. I really can't think straight here, please help!
my view :
<?php
echo form_open_multipart("adminFolder/admin/insert_picture");
echo form_upload("userfile", "Gambar Picture");
echo form_submit("input_picture", "Input now !!!");
?>
my controller :
public function insert_picture(){
$this->model_get->doUpload();
}
my model :
function doUpload(){
$path = './assets/images/';
chmod($path, 0777);
$config['upload_path'] = $path;
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$config['max_size'] = '6000';
$config['max_width'] = '1024';
$config['max_height'] = '768';
$config['overwrite'] = TRUE;
$this->load->library("upload", $config);
if(!$this->upload->do_upload()){
redirect("adminFolder/admin/insertPicture");
}else{
redirect("adminFolder/admin/adminPic");
}
}

Answer 1

You should require to pass filename in do_upload :
So your code of model will be :
if(!$this->upload->do_upload('userfile')){
redirect("adminFolder/admin/insertPicture");
}else{
redirect("adminFolder/admin/adminPic");
}
And this will work !! Please try

Answer 2

use in view:
input type="file" multiple="multiple" id="userfile" name="userfile"
Controller
In your controller method add this line
$this->gallery_model->do_upload($data);
Create One model class "gallery_model"
var $gallery_path;
var $gallery_path_url;
function Gallery_model() {
parent::__construct();
$this->gallery_path = realpath(APPPATH . '../images');
$this->gallery_path_url = base_url().'images/';
}
function do_upload() {
$config = array(
'allowed_types' => 'jpg|jpeg|gif|png',
'upload_path' => $this->gallery_path,
'max_size' => 2000
);
$this->load->library('upload', $config);
$this->upload->do_upload();
$image_data = $this->upload->data();
$config = array(
'source_image' => $image_data['full_path'],
'new_image' => $this->gallery_path . '/thumbs',
'maintain_ration' => true,
'width' => 150,
'height' => 100
);
$this->load->library('image_lib', $config);
$this->image_lib->resize();
}
function get_images() {
$files = scandir($this->gallery_path);
$files = array_diff($files, array('.', '..', 'thumbs'));
$images = array();
foreach ($files as $file) {
$images []= array (
'url' => $this->gallery_path_url . $file,
'thumb_url' => $this->gallery_path_url . 'thumbs/' . $file
);
}
return $images;
}
If you need Multiple Image Upload I can paste the Code for that also.!!
