既に画像をフォルダーにアップロードしています。今、その画像のサイズを 3 回変更したいと考えています。 300

次に、次のような関数で画像操作クラスのライブラリをロードします :: $this->load->library('image_lib');

これは私のコードです

$picturesData[$key][$key2] = $this->upload->data(); <<< this upload library is usable 

$file_name = $picturesData[$key][$key2]["file_name"];

//explode

$image_name = explode(".", $file_name);


//resize smallImage

$config['image_library'] = 'GD2';

$config['new_image'] = $path."/".$image_name[0]."_sSize";

// รูปที่เอามาใช้ในการ resize

$config['source_image'] = $picturesData[$key][$key2]["file_name"];

$config['create_thumb'] = TRUE;

$config['maintain_ratio'] = TRUE;

$config['width'] = 100;

$config['height'] = 100;

//mediumSize

$config['new_image'] = $path."/".$image_name[0]."_mSize";

$config['width'] = 200;

$config['height'] = 200;

//largeSize

$config['new_image'] = $path."/".$image_name[0]."_lSize";

$config['width'] = 300;

$config['height'] = 300;

$this->image_lib->initialize($config);

$this->image_lib->resize();


if(! $this->image_lib->resize()){

  echo $this->image_lib->display_errors();

}

これは私のエラーです!! 画像へのパスが正しくありません。

これは私のために働いているようです。$config['source_image'] = './画像パス/pic_name.jpg';

ソースへのパスを設定します.. base_url() を除外します

これを試して：-

$picturesData[$key][$key2] = $this->upload->data(); //this upload library is usable 
$file_name = $picturesData[$key][$key2]["file_name"];
//explode
$image_name = explode(".", $file_name);
//resize smallImage
$config['image_library'] = 'GD2';
$config['new_image'] = $path."/".$image_name[0]."_sSize.".$image_name[1];
//resize
$config['source_image'] = $picturesData[$key][$key2]["file_name"];
$config['create_thumb'] = TRUE;
$config['maintain_ratio'] = TRUE;
$config['width'] = 100;
$config['height'] = 100;
$this->image_lib->initialize($config);
$this->image_lib->resize();

//mediumSize
$config['new_image'] = $path."/".$image_name[0]."_sSize.".$image_name[1];
$config['width'] = 200;
$config['height'] = 200;
$this->image_lib->initialize($config);
$this->image_lib->resize();
//largeSize
$config['new_image'] = $path."/".$image_name[0]."_sSize.".$image_name[1];
$config['width'] = 300;
$config['height'] = 300;
$this->image_lib->initialize($config);
$this->image_lib->resize();

継続的な Girish Sinha の回答 :: これを変更 $config['source_image'] = $picturesData[$key][$key2]["file_name"]; $config['source_image'] = $picturesData[$key][$key2]["full_path"];
