为什么这段代码只加载10个最新帖子？

Question

有人为我编写了这个代码，以json格式加载帖子，但它只加载了10个最新帖子。如何更改它以加载所有帖子？

我试过？page = 2但是它没有用。

json url

代码

<?php

header("Content-type: application/json");

include ('wp-load.php');

$loop = new WP_Query(array( 'post_status' => 'publish', 'post_type' => 'post'));
if($loop->have_posts()) : while($loop->have_posts()) : $loop->the_post();

    $posts[] = array(
        'id' => $post->ID,
        'post_title' => $post->post_title,
        'post_content' => $post->post_content,
        'guid' => $post->guid,

        'image' => (has_post_thumbnail() ? get_the_post_thumbnail_url() : ''),
        'cats' => the_category_ID( false ),
        'post_date' => $post->post_date,
    );

endwhile; endif;
echo json_encode($posts);

?>

你应该看看docs。如果您想要所有帖子，那么预设posts_per_page参数将被设置为-1：

$loop = new WP_Query(
    array( 'post_status' => 'publish', 'post_type' => 'post', 'posts_per_page' => -1 )
);
