I've got a custom theme I build using an underscores starter theme. Inside one of my template files (page-talent.php) I've got this jQuery ajax function:
$.ajax({
type: 'POST',
url: '<?php echo admin_url('admin-ajax.php');?>',
dataType: "html", // add data type
// data: { action : 'get_ajax_posts' },
data: { action : 'get_ajax_posts' , filters: filters },
success: function( response ) {
console.log( response );
//alert(response);
$( '.posts-area' ).html( response );
}
});
})
then I'm running the code in admin-ajax.php inside the admin folder. I'm not sure why I did that (rather than someplace inside my theme directory) other than that's what some of posts in this forum said to do.
The Problem is that when wordpress updates it wipes it out. So the question is how can I put this inside my theme? I tried just calling a file inside my theme folder and it didn't work.
here is my code that I placed inside the existing admin-ajax.php right before the do_action( 'admin_init' ); section. Again this works fine inside this file, but it gets wiped out every time I update the version of wordpress.

If I add this to my functions.php file how do I call it from the Ajax function? Or If I just move the function get_ajax_posts() to a new file (talent-ajax.php) inside my theme folder how do I call that from the ajax function. In other words... what would this part be changed to reach that file?
url: '<?php echo admin_url('admin-ajax.php');?>',
