Here is an example. Hope this would help you :)
这是一个例子。希望这会帮助你:)
in your controller. lets say upload.php
在您的控制器中。让我们说upload.php
public function upload() {
if($this->input->post('upload')) {
$config['upload_path'] = APPPATH . 'your upload folder name here/';
$config['file_name'] = filename_here;
$config['overwrite'] = TRUE;
$config["allowed_types"] = 'jpg|jpeg|png|gif';
$config["max_size"] = 1024;
$config["max_width"] = 400;
$config["max_height"] = 400;
$this->load->library('upload', $config);
if(!$this->upload->do_upload()) {
$this->data['error'] = $this->upload->display_errors();
} else {
//success
}
}
}
Then in your view
那么在你看来
<?php echo form_open_multipart('upload'); ?>
<?php echo form_upload('userfile'); ?><br />
<?php echo form_submit('upload', 'Upload');?>
<?php echo form_close(); ?>
