image_hwstring ( $width, $height )
Parameters:

  • (int|string) $height Optional. Height attribute value.
Returns:
  • (string) HTML attributes for width and, or height.
Defined at:



Retrieve width and height attributes using given width and height values.

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.
