基本上，我正在尝试这样做，如果用户登录，所有待处理的帖子都可以投票。一旦获得10多张选票，它将被公布。

好了，不再使用数据库连接，现在使用元键，因此代码已经更改，以显示我现在拥有的内容

<?php 
//if the post is pending show
if(get_post_status() == \'pending\') {

//added a post_vote to the wp_posts database for use later

//if the user is logged in show
if ( is_user_logged_in() ) {

    add_post_meta( get_the_ID(), \'post_vote\', \'0\', true );
    $post_vote = get_post_meta( get_the_ID(), \'post_vote\' );
    echo \'Votes: \' .  print_r( $post_vote);
    //form for submit button
    echo "<form method=\\"POST\\" action=\\"";
    echo \'\';  //code in here for adding 1 to meta
    echo "\\">";
    echo \'<input type="button" name="submit" value="+">\';
    echo \'</form>\';

} else {
    echo\'Please Sign in to Vote\';
}

} else {
// do nothing
}
 ?>

    add_post_meta( get_the_ID(), \'post_vote\', \'0\', true );
    $post_vote = get_post_meta( get_the_ID(), \'post_vote\' );
    echo \'Votes: \' .  print_r( $post_vote);

它应该只说Votes: 0
