Php Codeigniter图像大小调整不工作
我试图将上传的图像调整到163px的高度,保持纵横比,然后将其上传到文件夹。我尝试了以下代码:Php Codeigniter图像大小调整不工作,php,codeigniter,image-processing,image-resizing,Php,Codeigniter,Image Processing,Image Resizing,我试图将上传的图像调整到163px的高度,保持纵横比,然后将其上传到文件夹。我尝试了以下代码: $id=1; // user id $this->load->library('image_lib'); $filename=$_FILES['file']['name']; $config['image_library'] = 'gd2'; $config['upload_path'] = './userdata/'.$id; $config['height'] = '163px
$id=1; // user id
$this->load->library('image_lib');
$filename=$_FILES['file']['name'];
$config['image_library'] = 'gd2';
$config['upload_path'] = './userdata/'.$id;
$config['height'] = '163px';
$config['maintain_ratio'] = TRUE;
//$config['master_dim'] = 'height';
$config['source_image'] = $filename;
$this->load->library('upload', $config);
$this->image_lib->initialize($config);
$this->image_lib->resize();
if(!$this->upload->do_upload('file'))
{
echo $this->data['error'] = $this->upload->display_errors();
}
但是,这会将图像上载到正确的文件夹中,但不会调整图像的大小。我上传了一张大小为*170*128*的图片,它按原样上传到文件夹中,没有调整大小。我的代码有什么问题
有人能帮我找到问题吗
提前感谢。试试这个更简洁的版本,高度或宽度的配置不需要px,因此您的代码有点混乱:
$id = 1;
$config = array(
'upload_path' => './userdata/'.$id,
'allowed_types' => 'gif|jpg|jpeg|png',
'encrypt_name' => true,
);
$this->load->library('upload', $config);
$field_name = "file"; // change this with your file upload part's field name if different
if ($this->upload->do_upload($field_name)) {
$image = $this->upload->data();
$config = array(
'image_library' => 'gd2',
'source_image' => $image['full_path'],
'maintain_ratio' => true,
'height' => 163,
);
$this->load->library('image_lib', $config);
if (!$this->image_lib->resize()) {
echo $this->image_lib->display_errors();
}
$this->image_lib->clear();
}
高度是否需要以px为单位?或者你可以只使用'163'?它应该是
$config['height']='163'
removepx
我已经在我的本地和它的工作中尝试过了,你能检查一下gd是否通过一个简单的phpinfo()调用安装或启用了吗?@Burak..我让它工作了。问题是我多次包含$this->load->library('image_lib')
。很高兴听到你修复了这个问题。
