edit_comment()

💡 云策文档标注

概述

edit_comment() 函数用于更新评论,基于 $_POST 数组中的值。它首先检查用户权限,然后处理评论数据,最后调用 wp_update_comment() 完成更新。

关键要点

  • 函数更新评论,依赖 $_POST 提供数据,如 comment_ID、comment_content 等。
  • 执行前验证当前用户是否具有 'edit_comment' 权限,否则终止执行。
  • 处理日期字段(如 aa、mm、jj)以设置 comment_date,并确保值在有效范围内。
  • 返回值为整数(1 表示成功更新,0 表示未更新)或 WP_Error 对象(失败时)。

代码示例

function edit_comment() {
    if ( ! current_user_can( 'edit_comment', (int) $_POST['comment_ID'] ) ) {
        wp_die( __( 'Sorry, you are not allowed to edit comments on this post.' ) );
    }

    if ( isset( $_POST['newcomment_author'] ) ) {
        $_POST['comment_author'] = $_POST['newcomment_author'];
    }
    if ( isset( $_POST['newcomment_author_email'] ) ) {
        $_POST['comment_author_email'] = $_POST['newcomment_author_email'];
    }
    if ( isset( $_POST['newcomment_author_url'] ) ) {
        $_POST['comment_author_url'] = $_POST['newcomment_author_url'];
    }
    if ( isset( $_POST['comment_status'] ) ) {
        $_POST['comment_approved'] = $_POST['comment_status'];
    }
    if ( isset( $_POST['content'] ) ) {
        $_POST['comment_content'] = $_POST['content'];
    }
    if ( isset( $_POST['comment_ID'] ) ) {
        $_POST['comment_ID'] = (int) $_POST['comment_ID'];
    }

    foreach ( array( 'aa', 'mm', 'jj', 'hh', 'mn' ) as $timeunit ) {
        if ( ! empty( $_POST[ 'hidden_' . $timeunit ] ) && $_POST[ 'hidden_' . $timeunit ] !== $_POST[ $timeunit ] ) {
            $_POST['edit_date'] = '1';
            break;
        }
    }

    if ( ! empty( $_POST['edit_date'] ) ) {
        $aa = $_POST['aa'];
        $mm = $_POST['mm'];
        $jj = $_POST['jj'];
        $hh = $_POST['hh'];
        $mn = $_POST['mn'];
        $ss = $_POST['ss'];
        $jj = ( $jj > 31 ) ? 31 : $jj;
        $hh = ( $hh > 23 ) ? $hh - 24 : $hh;
        $mn = ( $mn > 59 ) ? $mn - 60 : $mn;
        $ss = ( $ss > 59 ) ? $ss - 60 : $ss;

        $_POST['comment_date'] = "$aa-$mm-$jj $hh:$mn:$ss";
    }

    return wp_update_comment( $_POST, true );
}

注意事项

  • 函数内部依赖 $_POST 变量,确保在调用前已正确设置相关数据。
  • 权限检查使用 current_user_can(),需确保用户角色和权限配置正确。
  • 日期处理逻辑包括边界检查(如天数不超过 31),以避免无效日期。
  • 返回值可用于判断操作结果,处理失败时应检查 WP_Error。
