我已经使用CodeIgniter为我的个人网站编写了一个系统，并根据我的需要使用了GD2库来处理图像。在localhost和我用于测试的免费托管时它工作得很好。但是现在我正在从不同的提供商处获得付费托管服务，它不适用于jpg文件。它显示了破碎的图像图标。但在PNG文件中工作得很好。我试图显示操作错误，但没有显示。CodeIgniter图像处理JPG错误
这是我的媒体控制器，它操纵图像;
<?php defined('BASEPATH') OR exit('No direct script access allowed');
class Media extends CI_Controller
{
function sandbox($imageName , $width)
{
if(!is_file('uploads/sandbox/'.$width.'-'.$imageName)) {
$config['image_library'] = 'gd2';
$config['source_image'] = 'uploads/original/'.$imageName;
$config['new_image'] = 'uploads/sandbox/'.$width.'-'.$imageName;
$config['dynamic_output'] = FALSE;
$config['maintain_ratio'] = TRUE;
$config['master_dim'] = 'width';
$config['width'] = $width;
$config['height'] = $width;
$this->image_lib->initialize($config);
return $this->image_lib->resize();
} else {
return true;
}
}

{
if($this->sandbox($imageName, 920)) {

你记得在服务器上安装GD吗？我被那一次抓住了。 –
它调整大小并保存到另一个文件（上面的沙箱功能）时工作正常。无论是JPG还是PNG。 – SuperioREX
是自动加载的image_lib库吗？如果没有，那么在你给他们打电话之前你必须加载库。我认为错误报告已关闭。尝试开启错误报告功能 –
