最近几天正在做一个小型CMS,用到图片上传了,想利于CodeIgniter的上传类去实现,但测试中有好多问题,我把经过和要注意的地方分享一下!
复制代码 代码如下:
<?php echo form_open_multipart('picture/upload');?>
<?php echo form_upload('userfile');?>

<?php echo form_close();?>

controller代码:
function upload() {
$config['upload_path'] = './uploads/';

$config['allowed_types'] = 'gif|jpg|png';

$config['max_size'] = '1024';
$config['max_width'] = '1024';
$config['max_height'] = '768';

$config['file_name'] = time(); //文件名不使用原始名
$this->load->library('upload', $config);
if(!$this->upload->do_upload()) {
echo $this->upload->display_errors();
}else{

$data['upload_data']=$this->upload->data(); //文件的一些信息
$img=$data['upload_data']['file_name']; //取得文件名

echo $img."<br>";

foreach($data['upload_data'] as $item => $value){
echo $item.":".$value."<br>";

}

}
}
