Is there any way to exclude Autoptimize for IE7,8?

well, you could check do so with a bit of code that hooks into AO’s API;

add_filter('autoptimize_filter_noptimize','browser_noptimize',10,0);
function browser_noptimize() {
	if ( (str_pos($_SERVER['HTTP_USER_AGENT'],"MSIE 8.0") !== false) || (str_pos($_SERVER['HTTP_USER_AGENT'],"MSIE 7.0") !== false)) {
		return true;
	} else {
		return false;
	}
}

3 remarks;
* i have not tested this
* the user agent-strings (“MSIE 8.0” or “MSIE 7.0”) might not be correct, you’ll have to check those
* this will not work if you have a page caching plugin (as in that case the browser of the first request of a page will determine if all others see the page with or without AO)

hope this helps,

Hi Frank,

Thank you for your prompt reply. It is amazing to have such an support for a free plugin. It would be nice if you come up with a paid version of the plugin.

I think if I use your code and exclude the user agent string in my cache plugin then it should work fine. I will give it a test and come back to you.

Best regards,

theweblinsolutions,

You could dequeue the conditional IE css link and then add that css code within this IE6-8 hack after your regular css:

@media screen\,screen\9 {}

EDIT: doesn’t display well here: see the link for the correct syntax.
