Codeigniter image uploading not working in first attempt? - php

Question

I'm trying to create a image upload function for my e-commerce website. This is the function I used to upload files,
Image upload function
private function upload_product_image($name, $file) {
$this->load->library('upload');
$dir = $name;
if (!is_dir('store/' . $dir)) {
mkdir('store/' . $dir, 777, true);
}
$config['upload_path'] = './store/' . $dir . '/';
$config['allowed_types'] = 'jpg|png';
$config['encrypt_name'] = TRUE;
$this->upload->initialize($config);
if (!$this->upload->do_upload($file)) {
return null;
} else {
if (is_file($config['upload_path'])) {
chmod($config['upload_path'], 777);
}
$ud = $this->upload->data();
$source = $ud['full_path'];
$destination = $ud['full_path'];
$image = imagecreatefromjpeg($source);
imagejpeg($image, $destination, 75);
return $config['upload_path'] . $ud['file_name'];
}
}
Save product
public function save_product(){
*** other code ****
$dir = date('Ymdhis');
$dir = url_title($dir, 'dash', true);
$this->upload_product_image($dir, 'add-product-image1'),
*** other code ****
}
There are couple of issues when running this function,
Image is not uploaded in first attempt ( Add new product )
But It created the product folder
If I update the product images It is working fine.
If you could show me, what is the wrong with this code It'll be really helpful.
Thank you so much
