Hi!
I read a lot on this forum about problems in CI with using uploading files and validation fields at the same time, found a lot of discussions and tried to merge information in one topic.
The last version contains 2 file upload fileds and one text field:
Controller:
Code:
<?php
class upload extends Controller {
function index()
{
$this->load->library('form_validation');
$this->form_validation->set_rules('text', 'text', 'require');
$this->form_validation->set_rules('userfile_fake', 'userfile_fake', 'callback_file_check[TRUE]');
$this->form_validation->set_rules('userfile_fake2', 'userfile_fake2', 'callback_file_check[TRUE]');
if ($this->form_validation->run() == FALSE)
{
$this->load->view('upload');
}
else
{
echo "OK";
}
}
function file_check($file, $required)
{
$this->form_validation->set_message('file_check', '');
if (@$_FILES['userfile']['error'] == 4 && $required == 'FALSE')
{
return TRUE;
}
else
{
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '10000';
$config['max_width'] = '1024';
$config['max_height'] = '768';
$this->load->library('upload', $config);
if (!$this->upload->do_upload($file)) //we have problems
{
return FALSE;
}
else
{
return TRUE;
}
}
}
}
?>
Viewer:
Code:
<html>
<head>
<title>My Form</title>
<meta http-equiv="Content-Type" content="text/html;charset=UTF-8">
</head>
<body>
<?php echo validation_errors(); ?>
<?php echo $this->upload->display_errors(); ?>
<?php echo form_open_multipart('upload'); ?>
<input type="text" name="text" value="<?php echo set_value('text'); ?>" size="50" /><br />
<input type="hidden" name="userfile_fake2" value="userfile2">
<input type="file" name="userfile2" size="20" /><br />
<input type="hidden" name="userfile_fake" value="userfile">
<input type="file" name="userfile" size="20" />
<div><input type="submit" value="Submit" /></div>
</form>
</body>
</html>
I have some ideas to upgrade this code, may be later...
By the way, i don't understand why CI core coders don't intigrated file upload in validation :\
May be because it's not so easy...
