如何显示WP_USER_QUERY的分页链接？

时间：2012-07-04 作者：Osu

我想我已经差不多做到了，但是我无法获得分页链接来显示我正在创建的作者目录。

下面是我的代码，但我不知道如何获得链接，以便在作者页面之间导航。有人能帮我吗？我觉得这可能有用，但我不知道如何实现它：

paginate_links()

谢谢

这会让你离得很近。我还没有测试过它，但它与我使用过几次的设置几乎相同。

/*
 * We start by doing a query to retrieve all users
 * We need a total user count so that we can calculate how many pages there are
 */

$count_args  = array(
    \'role\'      => \'Subscriber\',
    \'fields\'    => \'all_with_meta\',
    \'number\'    => 999999      
);
$user_count_query = new WP_User_Query($count_args);
$user_count = $user_count_query->get_results();

// count the number of users found in the query
$total_users = $user_count ? count($user_count) : 1;

// grab the current page number and set to 1 if no page number is set
$page = isset($_GET[\'p\']) ? $_GET[\'p\'] : 1;

// how many users to show per page
$users_per_page = 5;

// calculate the total number of pages.
$total_pages = 1;
$offset = $users_per_page * ($page - 1);
$total_pages = ceil($total_users / $users_per_page);


// main user query
$args  = array(
    // search only for Authors role
    \'role\'      => \'Subscriber\',
    // order results by display_name
    \'orderby\'   => \'display_name\',
    // return all fields
    \'fields\'    => \'all_with_meta\',
    \'number\'    => $users_per_page,
    \'offset\'    => $offset // skip the number of users that we have per page  
);

// Create the WP_User_Query object
$wp_user_query = new WP_User_Query($args);

// Get the results
$authors = $wp_user_query->get_results();

// check to see if we have users
if (!empty($authors))
{
    echo \'<div class="author-entry">\';

你真的不应该用皮平的答案。查询效率很低。$user_count_query 在本例中，可以将数据库中最多999999个用户以及所有用户字段返回到脚本中。如果/当您的站点足够大时，这肯定会达到PHP的内存和/或时间限制。

但这可能是2012年唯一的解决方案。

这里有一个更好的方法。在这个例子中，我只有next and previous page 但是如果您确实需要编号分页，那么可以使用变量来构建它。据我所知，WordPress没有与WP\\u User\\u Query兼容的分页功能。

<?php

// Pagination vars
$current_page = get_query_var(\'paged\') ? (int) get_query_var(\'paged\') : 1;
$users_per_page = 2; // RAISE THIS AFTER TESTING ;)

$args = array(
    \'number\' => $users_per_page, // How many per page
    \'paged\' => $current_page // What page to get, starting from 1.
);

$users = new WP_User_Query( $args );

$total_users = $users->get_total(); // How many users we have in total (beyond the current page)
$num_pages = ceil($total_users / $users_per_page); // How many pages of users we will need

?>
    <h3>Page <?php echo $current_page; ?> of <?php echo $num_pages; ?></h3>
    <p>Displaying <?php echo $users_per_page; ?> of <?php echo $total_users; ?> users</p>

    <table>
        <thead>
            <tr>
                <th>First Name</th>
                <th>Last Name</th>
                <th>Email</th>
            </tr>
        </thead>

        <tbody>
            <?php
            if ( $users->get_results() ) foreach( $users->get_results() as $user )  {
                $firstname = $user->first_name;
                $lastname = $user->last_name;
                $email = $user->user_email;
                ?>
                <tr>
                    <td><?php echo esc_html($firstname); ?></td>
                    <td><?php echo esc_html($lastname); ?></td>
                    <td><?php echo esc_html($email); ?></td>
                </tr>
                <?php
            }
            ?>
        </tbody>
    </table>

    <p>
        <?php
        // Previous page
        if ( $current_page > 1 ) {
            echo \'<a href="\'. add_query_arg(array(\'paged\' => $current_page-1)) .\'">Previous Page</a>\';
        }

        // Next page
        if ( $current_page < $num_pages ) {
            echo \'<a href="\'. add_query_arg(array(\'paged\' => $current_page+1)) .\'">Next Page</a>\';
        }
        ?>
    </p>
第2页示例：

table of users, starting at page 2

<2018年6月8日更新：如果您想page numbers 这里不是下一页/上一页链接，而是如何设置。请注意，您需要将数字替换为页面链接，在本例中它们将不可单击（基于https://stackoverflow.com/a/11274294/470480, 修改为显示一致数量的中间数字，而不是添加“…”除非实际跳过了页面）。

您还可以看到my gist file 其中包含用于此目的的可重用函数。

$current_page = 5; // Example
$num_pages = 10; // Example

$edge_number_count = 2; // Change this, optional

$start_number = $current_page - $edge_number_count;
$end_number = $current_page + $edge_number_count;

// Minus one so that we don\'t split the start number unnecessarily, eg: "1 ... 2 3" should start as "1 2 3"
if ( ($start_number - 1) < 1 ) {
    $start_number = 1;
    $end_number = min($num_pages, $start_number + ($edge_number_count*2));
}

// Add one so that we don\'t split the end number unnecessarily, eg: "8 9 ... 10" should stay as "8 9 10"
if ( ($end_number + 1) > $num_pages ) {
    $end_number = $num_pages;
    $start_number = max(1, $num_pages - ($edge_number_count*2));
}

if ($start_number > 1) echo " 1 ... ";

for($i=$start_number; $i<=$end_number; $i++) {
    if ( $i === $current_page ) echo " [{$i}] ";
    else echo " {$i} ";
}

if ($end_number < $num_pages) echo " ... {$num_pages} ";
输出（从第1页到第10页）：

[1]  2  3  4  5  ... 10 
1  [2]  3  4  5  ... 10 
1  2  [3]  4  5  ... 10 
1  2  3  [4]  5  ... 10 

1 ...  3  4  [5]  6  7  ... 10 
1 ...  4  5  [6]  7  8  ... 10 

1 ...  6  [7]  8  9  10
1 ...  6  7  [8]  9  10
1 ...  6  7  8  [9]  10
1 ...  6  7  8  9  [10]

radley sustaire的回答应该得到充分肯定，但我发现了一个小问题，所以我在这里分享我的答案版本。

在我的版本中，我还按位置、关键字等过滤结果，因此某些页面的结果少于“$users\\u per\\u page”变量。因此，例如，如果我的每页用户数设置为显示10，但过滤器的结果仅返回3个用户，我会在页面顶部显示“显示3个用户中的10个”。显然这没有意义，所以我添加了一个简单的“if”语句来检查结果计数是否高于“$users\\u per\\u page”变量。

Radley，如果你用最新的答案编辑你的答案，我会很高兴地投票支持它，因为我认为它比Pippin的解决方案好。

因此，这是任何想要它的人的最终代码。

<?php

// Pagination vars
$current_page = get_query_var(\'paged\') ? (int) get_query_var(\'paged\') : 1;
$users_per_page = 10;

$args = array(
    \'number\' => $users_per_page, // How many per page
    \'paged\' => $current_page // What page to get, starting from 1.
);

$users = new WP_User_Query( $args );

$total_users = $users->get_total(); // How many users we have in total (beyond the current page)
$num_pages = ceil($total_users / $users_per_page); // How many pages of users we will need

if ($total_users < $users_per_page) {$users_per_page = $total_users;}

?>

            </tr>
        </thead>

        <tbody>
            <?php
            if ( $users->get_results() ) foreach( $users->get_results() as $user )  {

                $lastname = $user->last_name;
                $email = $user->user_email;
