我有在codeigniter上传图像的功能,在这里我可以上传任何图像,但是当我需要在我的网站上显示这些图像时,我将使用此代码: -
<img src="uploads/<?=$user->pic?>" width="250px" height="200px" />
如果图像大于250,图像显示不好。
那么我怎么能为我的照片做拇指。
public function do_upload($field) {
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '1000';
$config['max_width'] = '1024';
$config['max_height'] = '768';
$this->load->library('upload', $config);
if (!$this->upload->do_upload($field))
{
$error = array('error' => $this->upload->display_errors());
return $error;
}
else
{
$updata =$this->upload->data();
$data = $updata['raw_name'].$updata['file_ext'];
return $data;
}
}

在这里,你只需指定file_path就可以了(+宽度/高度) 如需更多选项,请查看here
public function resize_image($file_path, $width, $height) {
$this->load->library('image_lib');
$img_cfg['image_library'] = 'gd2';
$img_cfg['source_image'] = $file_path;
$img_cfg['maintain_ratio'] = TRUE;
$img_cfg['create_thumb'] = TRUE;
$img_cfg['new_image'] = $file_path;
$img_cfg['width'] = $width;
$img_cfg['quality'] = 100;
$img_cfg['height'] = $height;
$this->image_lib->initialize($img_cfg);
$this->image_lib->resize();
}
