如果不知道你的Instagram数据馈送对象是什么样子的，我会这样做，假设你已经有了$wp_query 对象中有帖子。

// we\'re going to merge both objects into one array so we can sort it
$merge_array = array();

// run through actual posts, assuming you already have a wp_query object built
while($loop->have_posts()): $loop->the_post();
    $merge_array[] = array(
        // store original post ID for later reference
        \'post_id\' => $post->ID,
        \'date\' => date(\'U\', strtotime($post->post_date)),
    );
endwhile;

// now loop through instagram stuff and fill up merge array with it as well
foreach($mysterious_instgram_ojbect as $instagram_image){
    $merge_array[] = array(
        \'post_id\' => false, // set this false to know it is not WP post object
        \'date\' => date(\'U\', $instagram_image->date), // guessing here
        // store more info here such as image URL and/or title
    );
}

现在，我们将重要的位填充到一个数组中。让我们把它们分类！

// sort them by date, function defined below
$merge_array_sorted = array_msort($merge_array, array(\'date\' => SORT_DESC));

并循环它们以获得最终输出。

foreach($merge_array_sorted as $feed_object){
    echo date(\'F js\', $feed_object[\'date\']);
    if($feed_object[\'post_id\']){
        // is post, treat as wordpress post!
        echo get_the_title($feed_object[\'post_id\']);
        echo get_permalink($feed_object[\'post_id\']);
    } else {
        // is instagram, treat accordingly
    }
}

把这个放在你的函数中。这是一个非常棒的多维数组分类器，如上所述。

// world famous multidimensional array sort function
function array_msort($array, $cols) {
    $colarr = array();
    foreach ($cols as $col => $order) {
        $colarr[$col] = array();
        foreach ($array as $k => $row) { $colarr[$col][\'_\'.$k] = strtolower($row[$col]); }
    }
    $eval = \'array_multisort(\';
    foreach ($cols as $col => $order) {
        $eval .= \'$colarr[\\\'\'.$col.\'\\\'],\'.$order.\',\';
    }
    $eval = substr($eval,0,-1).\');\';
    eval($eval);
    $ret = array();
    foreach ($colarr as $col => $arr) {
        foreach ($arr as $k => $v) {
            $k = substr($k,1);
            if (!isset($ret[$k])) $ret[$k] = $array[$k];
            $ret[$k][$col] = $array[$k][$col];
        }
    }
    return $ret;
}

这是一个松散的例子。对象现在应该按Unix时间戳排序，您可以将其转换回更有用的日期。您可以很容易地引用WP函数，如the_content() 穿上你的最后一件衣服foreach 环如果需要进一步解释，请告诉我。
