wordpress 后臺添加自定義按鈕導(dǎo)出csv
在wp-admin/edit.php中找到如下代碼：
<?php if ( current_user_can( $post_type_object->cap->create_posts ) ) { echo ' <a href="' . esc_url( admin_url( $post_new_file ) ) . '" class="page-title-action">' . esc_html( $post_type_object->labels->add_new ) . '</a>'; }
在上面代碼的下一行加入如下代碼：
if ($post_type == 'aaa') { echo ' <a href="'.esc_url( admin_url('admin-ajax.php?action=export_permanent_csv')).'" class="page-title-action">CSVをエクスポート</a>'; }
$post_type 是在這個文件的頭部獲取的文章的類型。
在wp-content/themes/hcr/functions/admin.php
function export_permanent_csv() { $args = array( 'post_type' => 'aaa', 'numberposts' => -1, 'meta_key' => 'mark_id', 'orderby' => 'meta_value_num', 'order' => 'ASC', ); $posts = get_posts($args); if (empty($posts)) { return; } $noNumber = 1; foreach ($posts as $post) { $metaData = get_post_meta($post->ID); $data = [ $metaData['mark_id'][0], $noNumber, $post->post_title, $metaData['prmnnt_address'][0], $metaData['prmnnt_tel'][0], $metaData['prmnnt_fax'][0], $metaData['prmnnt_site'][0], $metaData['prmnnt_time'][0], $metaData['prmnnt_closing'][0], $metaData['prmnnt_service'][0], $metaData['prmnnt_class'][0], $post->post_type, ]; $csv_output .= '"'.implode('","', $data).'"'."n"; $noNumber++; } $csv_output .= "n"; $filename = $file."_".date("Ymd", time()); header("Content-type: application/vnd.ms-excel"); header("Content-disposition: csv" . date("Y-m-d") . ".csv"); header("Content-disposition: filename=".$filename.".csv"); print $csv_output; exit; } add_action('wp_ajax_export_permanent_csv', 'export_permanent_csv');
