尝试将2添加到整数时出现此错误。我正在使用Codeigniter框架。当值为整数时,不支持的操作数类型
Fatal error: Unsupported operand types in D:\wamp\www\application\libraries\Gen_images.php on line 180
这里就是其所谓的:
// Now process the image
var_dump($this->upload->data('image_width'));
$this->gen_login->resize($file_name, $this->upload->data('image_width'), $this->upload->data('image_height'));
我得到line 180
错误是:
$config['width'] = $width + 2;
所以我想$宽度必须是一个数组或字符串,所以我不会无法添加,但var dump
显示:
array
'file_name' => string 'genyx_1341414096.jpg' (length=20)
'file_type' => string 'image/jpeg' (length=10)
'file_path' => string 'D:/wamp/www/beer/uploads/' (length=25)
'full_path' => string 'D:/wamp/www/beer/uploads/genyx_1341414096.jpg' (length=45)

'image_height' => int 479
'image_type' => string 'jpeg' (length=4)
'image_size_str' => string 'width="720" height="479"' (length=24)
任何人都可以帮助我吗?
你有没有尝试像(int)$ width一样投射$ width? –
'var_dump($ witdh)'的结果是什么? – Florent
var_dump($ width);似乎给予完全一样的另一个var_dump ... – Adam
