I have a wordpress site, and I need to move some javascript to the footer. I am using a theme (photocrati) that only uses the wp_enqueue_scripts tag a total of 4 times in the header.php file.
What I’m looking to do is find a way, hopefully dynamically, to move the javascript files to the footer. I realize this would be much easier using the $in_footer if they were properly referenced using the enqueue_scripts, but alas, that’s not the case.
Being that this is a photography studio website, I need to do everything I can to reduce loading time. Now, obviously I’m not about to move CSS to the footer like google page speed recommends because I don’t want my site being rendered unformatted when the visitor first views it.
After doing everything else I can (I obviously can’t do anything about minimizing or setting leveraging browser caching on files not hosted with my site, ie the google analytics js file), the page speed insights recommends, “Remove render-blocking JavaScript and CSS in above-the-fold content” is all I have left. I am hoping once I move the js to the footer my page load time will be under 5 seconds considering it is now just under 6 and there are 19 script resources.
Hopefully someone can give me some guidance on being able to do this through some PHP code added to the functions.php file since I (for the most part) understand what’s going on with PHP code when I am writing. But, I am having a hard time deciphering what is going on in the header file, and being able to find all 19 js files to delete them from the header file and enqueue them properly.
EDIT Here is the header.php file. I’ve noticed that some of the scripts are not even called here in any way because when I search the file for say “hoverintent.js” it’s nowhere to be found, but if I search the source code after my page loads, sure enough it’s in the header.

There’s the part of the header.php file that contains the js file references. As I said before, not all of them are called through the header.php file.
Enqueue script has a fifth parameter, which is a boolean, false as default. If you set to true, your scripts will be in the footer. In case, your theme has the
wp_footer()method in the footer.An example:
