我正在开发一个web应用程序。在我的应用程序中,我上传图像到服务器,然后调整它的大小。我上传到服务器成功。但是当我调整图像大小时,它不是在调整图像大小。但它也不会抛出错误。
这是我的图片文件上传模型
class file_helper extends CI_Model{
function __construct()
{
parent::__construct();
$this->load->library('image_lib');
}
function generateRandomFileName()
{
$rand = rand(10000,99999);
$file_name = time().$rand;
return time().$rand;
}
function uploadImage()
{
$name = $this->generateRandomFileName();
$config['upload_path'] = './'.UPLOAD_FOLDER.'/';
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$config['file_name'] = $name;
$this->load->library('upload', $config);
if ( !$this->upload->do_upload('userfile'))
{
return FALSE;
}
else
{
$data = $this->upload->data();
$data['virtual_path'] = UPLOAD_FOLDER."/".$name.".".$data['file_ext'];
return $data;
}
}
function resizeImage($path)
{
$config['image_library'] = 'gd2';
$config['source_image'] = '/'.$path;
$config['create_thumb'] = TRUE;
$config['maintain_ratio'] = TRUE;
$config['width'] = 300;
$config['height'] = 50;
$this->load->library('image_lib', $config);
if ( ! $this->image_lib->resize())
{
print_r($this->image_lib->display_errors());
}
else{
echo "Ok";
}
}
}
正如您在模型中看到的,我在成功时打印出"Ok",在失败时打印出错误。我传递的路径类似于"uploads/23344545.png"。但是这个调整大小的函数总是打印"Ok",但是图像没有调整大小。我的代码有什么问题?
上传时需要调整图片大小
function uploadImage()
{
$name = $this->generateRandomFileName();
$config['upload_path'] = './'.UPLOAD_FOLDER.'/';
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$config['file_name'] = $name;
$config['width'] = 300;
$config['height'] = 50;
$this->load->library('upload', $config);
if ( !$this->upload->do_upload('userfile'))
{
return FALSE;
}
else
{
$data = $this->upload->data();
$data['virtual_path'] = UPLOAD_FOLDER."/".$name.".".$data['file_ext'];
return $data;
}
}
