Question

当我尝试从json打印结果时，我正在尝试一个问题，这是我的代码：

_js_repo.php：

$db=new Database;
$res=$db->query("SELECT id, name, text, link as href, parent_id FROM repositorio");
//iterate on results row and create new index array of data
while( $row = mysqli_fetch_assoc($res) ) {
$data[] = $row;
}
$itemsByReference = array();
// Build array of item references:
foreach($data as $key => &$item) {
$itemsByReference[$item['id']] = &$item;
}
// Set items as children of the relevant parent item.
foreach($data as $key => &$item) {
if($item['parent_id'] && isset($itemsByReference[$item['parent_id']])) {
$itemsByReference [$item['parent_id']]['nodes'][] = &$item;
}
}
// Remove items that were added to parents elsewhere:
foreach($data as $key => &$item) {
if($item['parent_id'] && isset($itemsByReference[$item['parent_id']]))
unset($data[$key]);
}
// Encode:
echo json_encode($data);

repositorio.php：

<script>
    jQuery(document).ready(function(){
        jQuery.ajax({
            url: "_js_repo.php",
            cache: false,
            success: function(response){
                $('#treeview').treeview({
                    data: response,
                    showBorder: false,
                    enableLinks: true,
                    expandIcon: 'fa fa-angle-right',
                    collapseIcon: 'fa fa-angle-down',
                    nodeIcon: 'fa fa-folder'
                });
            }});
    });
</script>

您可以在bramsc.com.mx/repositorio.php和bramsc.com.mx/_js_repo.php上查看实时问题

Chrome浏览器检查器：

repositorio.php上的输出为空，但在_js_repo.php中看起来不错。非常感谢您的帮助。
