How does DedeCms get the height and width of the thumbnail?
DreamWeaver DedeCms gets the height and width of the thumbnail
Recommended learning:DreamWeavercms
Code requirements for certain waterfall flows The image must have a height, and the default thumbnail of Dreamweaver is just the stored image path. If you want to output the height of the image, you must use other methods. At present, I only think of using the getimagesize function, which is also a relatively simple implementation. Solution,
But there seems to be a problem in the actual application process, and I can’t figure out the reason. The specific manifestation is
$GLOBALS['cfg_basehost'] with www It cannot be obtained normally, such as http://www.xxx.com. If it is http://xxx.com, it can be obtained normally, which is extremely strange.
Of course, this method consumes a lot of resources.
include\helpers\extend.helper.php Finally add
if ( ! function_exists('getheight')) { function getheight($litpic){ $litpicc = $GLOBALS['cfg_basehost'].$litpic; $arr = getimagesize($litpicc); $resault = $arr[1]; // 此为高度 //$resault = $arr[0]; //此为宽度 return $resault; } }
Use [field:litpic function="getheight(@me)"/] directly in the template to output the image height
Example
<img src="[field:litpic/]" height=" [field:litpic function="getheight(@me)"/]">
The second method (recommended):
Add the following code before inserting into the database in /dede/article_add.php:
//获取缩略图宽度及高度 $litpicc = $GLOBALS['cfg_basehost'].$litpic; $arr = getimagesize($litpicc);
$arr[ 0] is the width, $arr[1] is the height
Just insert these two values into the database (please add the corresponding fields before)
This will save a lot of money through database calls system resource.
