我成功了。如何发布不同类型的\\u mime\\u？我在函数中添加了post\\u mime\\u type。php

add_filter(\'upload_mimes\', \'pixelo_upload_types\');
   function pixelo_upload_types($existing_mimes=array()) {
   $existing_mimes[\'otf\'] = \'otf\';
   $existing_mimes[\'ttf\'] = \'ttf\';
return $existing_mimes; }

<?php
$args = array(
\'numberposts\'     => -1,
\'orderby\'         => \'menu_order\',
\'order\'           => \'ASC\',
\'post_type\'       => \'attachment\',
\'post_parent\'     => $post->ID,
\'post_mime_type\' => \'ttf\'
);

$font = get_posts($args);
if($font) {
    foreach($font as $key => $data) : ?>
       <option value="<?php echo $data->ID; ?>"><?php echo $data->post_title; ?></option>
    <?php endforeach;
} ?>
