It seems the problem is you send the form request to welcome/do_upload
, and call the Welcome::do_upload()
method in another one by $this->do_upload()
.
Hence when you call the $this->do_upload();
within your second method, the $_FILES
array would be empty.
And that's why var_dump($data['upload_data']);
returns NULL
.
If you want to upload the file from welcome/second_method
, send the form request to the welcome/second_method where you call $this->do_upload();
.
Then change the form helper function (within the View) as follows1:
// Change the 'second_method' to your method name
echo form_open_multipart('welcome/second_method');
CodeIgniter has documented the Uploading process very well, by using the File Uploading library.
You could take a look at the sample code in the user guide; And also, in order to get a better understanding of the uploading configs, Check the Config items Explanation section at the end of the manual page.
Also there are couple of articles/samples about the file uploading in CodeIgniter, you might want to consider:
Just as a side-note: Make sure that you've loaded the url
and form
helper functions before using the CodeIgniter sample code:
// Load the helper files within the Controller
$this->load->helper('form');
$this->load->helper('url');
1. The form must be "multipart" type for file uploading. Hence you should use form_open_multipart()
helper function which returns:
<form method="post" action="controller/method" enctype="multipart/form-data" />
