将wordpress $ current_user-> ID从php文件发送到外部Javascript文件 [英] Send wordpress $current_user->ID from php file to external Javascript file

问题描述

我试图根据登录的伙伴新闻用户将KML文件动态加载到地图中.当我在javascript文件中对userID进行硬编码时，一切正常，但是我需要它来动态加载当前用户的用户ID

I am trying to dynamically load a KML file into a map depending on which buddy press user is logged in. Everything works fine when I hardcode a userID in the javascript file, but I need it to dynamically load the current user user ID.

这是JavaScript文件:

Here is the javascript file:

    function initialize(){
    //MAP
      //manually set user ID to zero
      //var current_user =0; 
      var current_user;
      //var current_user = "<?php get_currentuserinfo(); echo $current_user->ID?>"
      var latlng = new google.maps.LatLng(90.64138205695923,-45.38903528363647);
      var options = {
         zoom: 16,
         center: latlng,
         mapTypeId: google.maps.MapTypeId.ROADMAP
         };

      map = new google.maps.Map(document.getElementById("map_canvas"), options);

      var kmlLayer = new google.maps.KmlLayer('http://www.mysite.com/timeline_'+current_user+'.kml');
      kmlLayer.setMap(map);  

这就是我在php文件中的循环内的内容:

This is what i have in the php file, within the loop:

    $("#address1").click( function() {
                initialize();
                var currentUser = <?php get_currentuserinfo(); echo $current_user->ID?>;
                    $current_user = currentUser;

                });

就像我提到的那样，如果我对用户ID进行硬编码，它可以工作，但是我不确定如何将用户ID从PHP传递到javascript文件.

Like I mentioned, it works if i hard code the user ID, but I am not sure how to pass the UserID from PHP to the javascript file.

推荐答案

正如我之前的评论所建议的，我认为这将解决您的问题:

As my earlier comment suggested, I think this will solve your issue:

在js文件中:

...
function initialize(current_user) {
    ...
}
...

在php中:

...
<script type="text/javascript">
    $("#address1").click( function() {
        initialize(<?=json_encode($current_user->ID)?>);
    });
</script>
...
