我一直在尝试上传和调整图片大小 . 上传似乎终于有效,但它没有调整大小 .
在我的构造函数中,我正在加载库
$this->load->library('image_lib');
然后在我的函数中我调用resize并上传
$this->require_auth();
$img = $this->input->post('photo1');
$config['upload_path'] = './HTML/files/';
$config['file_name'] = 'photo1.jpg';
$config['file_path'] = './HTML/files/photo1.jpg';
$config['max-size'] = 2000;
$config['image_library'] = 'gd2';
$config['source_image'] = $config['file_path'];
$config['create_thumb'] = TRUE;
$config['maintain_ratio'] = FALSE;
$config['width'] = 549;
$config['height'] = 549;
$config['overwrite'] = TRUE;
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$config['new_image'] = $config['file_path'];
$this->load->library('image_lib', $config);
$this->image_lib->resize();
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload('photo1')){
$error = array('error' => $this->upload->display_errors());
var_dump($error);
}else{
$this->blog_model->editServiceImg1($config['file_path']);
redirect('/blog');
}
我也尝试过这个
$this->require_auth();
$img = $this->input->post('service_photo1');
$config['upload_path'] = './HTML/files/';
$config['file_name'] = 'service_photo1.jpg';
$config['file_path'] = './HTML/files/service_photo1.jpg';
$config['max-size'] = 2000;
$config['overwrite'] = TRUE;
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload('service_photo1')){
$error = array('error' => $this->upload->display_errors());
var_dump($error);
}else{
$config['image_library'] = 'gd2';
$config['source_image'] = $config['file_path'];
$config['create_thumb'] = TRUE;
$config['maintain_ratio'] = FALSE;
$config['width'] = 549;
$config['height'] = 549;
$config['new_image'] = $config['file_path'];
$this->image_lib->initialize($config);
$this->image_lib->resize();
$this->blog_model->editServiceImg1($config['file_path']);
redirect('/blog');
}
有什么我想念的吗?我也尝试过在初始上传后调整大小,这似乎也没有做任何事情 . 任何帮助将非常感激 .

如果上述代码无效,请检查上传图像的文件夹权限 .
您还可以通过以下方式为该文件夹授予777权限: -
sudo chmod -R 777 path
解决方案一定会对您有所帮助
我多次查看这段代码,最后解决了这个问题 . 看来,当你有
在你的代码中,它将创建一个缩放比例的缩略图,如果你不告诉它去哪里,它会将它隐藏在一个文件夹中 . 因此调整大小正在工作,而不是正确的图像 .
要解决这个问题,我将上面改为 .
