If you want a quick and dirty fix to add “edit” links to your repeater post selectors, add this snippet into the input.js file (adjust the wp-admin url if needed):
/wp-content/plugins/acf-repeater/js/input.js
on line 125 at the end of the render function
/*EDIT LINK START*/
$('.repeater, .field_type-post_object').find('.post_object').each(function(){
var $editLink = $(this).parent().find('.edit-field-link');
if($editLink.length == 0)
{
$editLink = $('<a href="/wp-admin/post.php?post='+$(this).val()+'&action=edit" class="edit-field-link">Edit</a>');
$(this).before($editLink);
}
});
$('.repeater, .field_type-post_object').on('change','.post_object',function(){
var $editLink = $(this).parent().find('.edit-field-link');
$editLink.attr('href','/wp-admin/post.php?post='+$(this).val()+'&action=edit');
});
/*EDIT LINK END*/
