我正在制作一个 WordPress 插件来与我们的图书馆系统集成。我正在尝试创建一个带有搜索表单的页面来搜索数据库。我在我们的图书馆服务器(它在我们的本地网络上)上创建了一个 API，因此该站点可以与我们的图书馆后端连接。
我正在尝试对从 API 提取的结果进行分页，数据在 json 中。我创建了以下代码以从 API 获取 json 并将其转换为 PHP 数组，它还没有实现搜索:
add_shortcode("book_search_form", "book_search_form");
function book_search_form() {
$api_url = get_option('api_url');
$api_key = get_option('api_key');
$data = file_get_contents("$api_url/book/index.php/name/awesome/$api_key");
$data = (array)json_decode($data, true);
echo '<pre>';
var_dump($data);
echo '</pre>';
}
这是输出:
array(2) {
[0]=>
array(22) {
["barcode"]=>
string(12) "000015427928"
["name"]=>
string(74) "Janice VanCleave's 201 awesome, magical, bizarre & incredible experiments."

我正在尝试创建分页，因为一些查询包含 50 或更多本书。我以前用 mysql 做过这个，但我不知道如何用数组来做。
谢谢!
最佳答案
以下是您将用于分页的代码原型(prototype)，只需更改它即可获得所需的结果。
if(isset($_GET['page']) && isset($_GET['paramsfordataonnextpage']))
{
$page=$_GET['page']; // get the value of the page from your url
$recordsPerPage=10; // number of records you want on your page
$array=//from your service
$index=($page*$recordsPerPage)-1;
$recordsToBeDisplayed = array_slice($array,$index,$recordsPerPage);// this array contains all the records you would want to display on a page;
$total_pages=ceil(count($array)/$recordsPerPage);
}
else {
//use default values
}
<html>...<body><div id="records"><!-- use the array created above to display records -->
</div>
<div id="pagination">
for($j=1;$j<=$total_pages;$j++){
if($j==$page)
{?>
<li style="display: inline;"><a href="/yourpaginationpage.php?paramsfordataonnextpage=&page=<?=$j?>"><u><?=$j?></u></a></li>
<?}else{?>
<li style="display: inline;"><a href="/yourpaginationpage.php?paramsfordataonnextpage=&page=<?=$j?>"><?=$j?></a></li>
<?}}?>
</div>
</body>
...
</html>
