我有一个Wordpress头痛。我正在建立一个Wordpress前端，该前端连接到我用来提取库存详细信息的CRM上，然后将其显示在Wordpress中。
除了一件事-分页，一切都正常。我一直通过分页的var并使用各种插件来进行Wordpress分页，但是我的查询是手工编码的PHP PDO请求，没有利用Wordpress的功能。
即使结果是由外部资源提供的，没有人知道如何在Wordpress中强制分页吗？
如果有帮助，我的查询如下（在functions.php中）：
$dbh = new PDO("mysql:host=$hostname;dbname=cl15-l3ase2015", $username, $password);
$stmt = $dbh->prepare("SELECT * FROM cars LIMIT 0,$limit");
$stmt->bindParam(1, $id, PDO::PARAM_INT);
$stmt->execute();
$total = $stmt->rowCount();
$data = $stmt->fetchAll(PDO::FETCH_ASSOC);
$data['total_results'] = $total;
return $data;
...并且模板受以下内容控制：
<div class="col-xs-12 col-sm-8 col-md-8 col-lg-8 mask-left mask-right">
<div class="body-copy-alt">
<?php
$posts_per_page = 2;
$post_count = $total;
$vehicle_group = get_latest_vehicles(10000);
$total = $vehicle_group['total_results'];
?>
<div class="col-xs-12 col-sm-7 col-md-8 col-lg-8 no-padding-left">
<h4 class="top"><strong><span id="total-holder"><?php echo $total;?></span> vehicles found</strong>, drive away in five days</h4>
</div>
<div class="col-xs-12 col-sm-5 col-md-4 col-lg-4 no-padding-right mask-left">
<select name="refine" id="refine">
<option value="null" disabled>Select Lowest Deposit</option>
<option value="100">100</option>
</select>
</div>
<div class="clearfix"></div>
<?php
foreach($vehicle_group as $current_vehicle) {
$current_id = $current_vehicle['id'];
$vehicle_manufacturer = $current_vehicle['carMake'];
$vehicle_model = $current_vehicle['carModel'];
$vehicle_registration = $current_vehicle['carReg'];
$vehicle_fuel = get_specific('FUEL', $current_vehicle['fuel']);
$vehicle_transmission = get_specific('TRANSMISSION', $current_vehicle['transmission']);
$vehicle_mileage = $current_vehicle['mileage'];
$vehicle_mpg = $current_vehicle['economy'];
$vehicle_year = $current_vehicle['year'];
$finance_data = get_finance_data($current_id);
$vehicle_deposit_min = $finance_data['minDeposit'];
$vehicle_weekly_payments = $finance_data['weeklyPayments'];
$gallery_data = get_gallery_images($current_id);
if(isset($current_id)) {

....
WordPress next_posts_link和previous_posts_link所做的所有操作均以正确的格式创建链接，以获取下一页和上一页。由于您使用的不是帖子或页面，因此这些链接的格式不正确。
如果为数据库起始位置引入其他参数，则可以使用自定义CRM来完成相同的操作。详细信息将取决于您的应用程序的确切工作方式，但基础知识是：
您可以修改代码，以引入一些了解数据库中从何处开始的方法。例如：
$dbh = new PDO("mysql:host=$hostname;dbname=cl15-l3ase2015", $username, $password);
$start = isset($_GET['start']) ? $_GET['start'] : 0;
$stmt = $dbh->prepare("SELECT * FROM cars LIMIT $start,$limit");
$stmt->bindParam(1, $id, PDO::PARAM_INT);
$stmt->execute();
$total = $stmt->rowCount();
$data = $stmt->fetchAll(PDO::FETCH_ASSOC);
$data['total_results'] = $total;
return $data;
您可以创建自己的功能来完成相同的事情。
例如，如果$ start是当前页面的起始位置：
function my_next_link($start, $limit) {
$new_start = $start + $limit;
if ($new_start <= number of records in the CRM) {
echo "<a href=\"http://example.com/mypage?start=$start\">Next</a>";
}
}
function my_previous_link($start, $limit) {
if ($start > 0) {
$new_start = max(0, $start - $limit);
echo "<a href=\"http://example.com/mypage?start=$start\">Previous</a>";
}
