image_hwstring() WordPress Function
image_hwstring() is a function in WordPress that allows you to output the width and height of an image as a string. This is useful for outputting images in HTML or CSS.
image_hwstring( int|string $width, int|string $height ) #
Retrieve width and height attributes using given width and height values.
Description
Both attributes are required in the sense that both parameters must have a value, but are optional in that if you set them to false or null, then they will not be added to the returned string.
You can set the value using a string, but it will only take numeric values. If you wish to put ‘px’ after the numbers, then it will be stripped out of the return.
Parameters
- $width
(int|string)(Required)Image width in pixels.
- $height
(int|string)(Required)Image height in pixels.
Return
(string) HTML attributes for width and, or height.
