将文件从一个目录移动到另一个目录

我有这个功能：

function attachment_selectbox_edit($form_fields, $post) {

$select_options = array(
    "no" => "No",
    "yes" => "Yes"
);

// get the current value of our custom field
$current_value = get_post_meta($post->ID, "_my_select", true);

// build the html for our select box
$mySelectBoxHtml = "<select name=\'attachments[{$post->ID}][my_select]\' id=\'attachments[{$post->ID}][my_select]\'>";
foreach($select_options as $value => $text){

    // if this value is the current_value we\'ll mark it selected
    $selected = ($current_value == $value) ? \' selected \' : \'\';

    // escape value for single quotes so they won\'t break the html
    $value = addcslashes( $value, "\'");

    $mySelectBoxHtml .= "<option value=\'{$value}\' {$selected}>{$text}</option>";
}
$mySelectBoxHtml .= "</select>";

// add our custom select box to the form_fields
$form_fields["my_select"]["label"] = __("Move the file?");
$form_fields["my_select"]["input"] = "html";
$form_fields["my_select"]["html"] = $mySelectBoxHtml;

return $form_fields;
}
add_filter("attachment_fields_to_edit", "attachment_selectbox_edit", null, 2);

当$current\\u value==“yes”时，我想将文件从“uploads”目录移动到“uploads/new目录”。

你能帮帮我吗？

add_filter(\'??attachment_fields_save_filter??\',\'move_attachment_directory\',10,2); function move_attachment_directory($form_fields,$post) { $attach_id = $post->ID; if (!isset($_POST[\'attachments\'][$attach_id][\'my_select\'])) {return;} if ($_POST[\'attachments\'][$attach_id][\'my_select\'] == \'no\') {return;} // set directories $uploaddir = wp_upload_dir(); $newdirectory = \'new-directory\'; // or whatever it is // get attachment metadata $attachdata = wp_get_attachment_metadata($attach_id); // move original image $filepath = trailingslashit($uploaddir).$attachdata[\'file\']; $newfilepath = trailingslashit($uploaddir).trailingslashit($newdirectory).$attachdata[\'file\']; rename($filepath,$newfilepath); $attachdata[\'file\'] = trailingslashit($newdirectory).$attachdata[\'file\']; // move each attachment size too foreach ($attachdata[\'sizes\'] as $size => $data) { $file = $data[\'file\']; $filepath = trailingslashit($uploaddir).$data[\'file\']; $newfilepath = trailingslashit($uploaddir).trailingslashit($newdirectory).$data[\'file\']; rename($filepath,$newfilepath); $data[\'file\'] = trailingslashit($newdirectory).$data[\'file\']; $attachdata[\'sizes\'][$size] = $data; } // update attachment metadata wp_update_attachment_metadata($attach_id,$attachdata); }

Apply filters on date format

我使用Wordpress主题，其中格式日期和时间直接编码为两种格式：<?php the_time(\'d M\'); ?> <?php the_time(\'H:i\'); ?> 我想要的：显示wordpress选项中定义的日期和时间我不想在子主题中创建修改过的模板，我更喜欢使用函数。我已经在函数中添加了php。php此代码有效：add_filter( \'the_time\', \'changer_date_format\', 10, 1 ); //o
