当 2 个不同的图像上传到 2 个不同的文件夹时,图像 uploaded.but 不会创建缩略图
When 2 different images are uploaded to 2 different folders,then the images are uploaded.but the thumbs are not created
这是我的控制器函数,请帮我创建两个图像的拇指。只有图像会上传到文件夹中。我创建了一个名为 resize 的函数来创建拇指。这也在控制器中给出。

调整大小功能
public function resize($source, $destination, $width, $height) {
$config['image_library'] = 'gd2';
$config['source_image'] = $source;
$config['create_thumb'] = TRUE;
$config['maintain_ratio'] = TRUE;
$config['width'] = $width;
$config['height'] = $height;
$config['new_image'] = $destination;
$this->load->library('image_lib', $config);
$this->image_lib->resize();
}
难不成你点赞的文件夹(assets/images/b2bproduct/thump/
和assets/images/b2blogo/thump/
)不存在?
这很可能是一个简单的拼写错误,例如 thump
而不是 thumb
。
编辑:
您真的不必多次加载 upload
和 image_lib
库。一开始就做一次。之后,您可以使用 $this->upload->initialize($config);
或 $this->image_lib->initialize($config);
到您现在尝试重新加载库的所有这些地方。
为了使您的代码正常工作,您至少应在 resize
函数中的 $this->image_lib->resize();
之前添加 $this->image_lib->initialize($config);
。
首先,您在 function add
中加载了两次库,请在函数顶部加载一次。
在调整大小时使用 $this->image_lib->initialize($config)
,如下所示
public function resize($source, $destination, $width, $height) {
$config['image_library'] = 'gd2';
$config['source_image'] = $source;
$config['create_thumb'] = TRUE;
$config['maintain_ratio'] = TRUE;
$config['width'] = $width;
$config['height'] = $height;
$config['new_image'] = $destination;
$this->load->library('image_lib');
$this->image_lib->initialize($config);
$this->image_lib->resize();
}
