Set Transient does nothing

我试图在自定义查询上设置一个瞬态，但它似乎不起作用。每次我刷新页面时，它仍然会每次显示不同的帖子。

在阅读了transients api之后，我开始相信设置transient会将我的第一个查询存储为与它查询的帖子完全相同的帖子，并在下次再次显示它们，而不必再次执行整个查询。

是我错了还是我做错了什么？

这是我的全部UPDATED 查询：

if(isset($_COOKIE[\'myCookie\']) && $_COOKIE[\'myCookie\'] == $f_a){

// Check for transient. If none, then execute WP_Query
if ( false === ( $akerargs = get_transient( \'county_query\' ) ) ) {

    $akerargs = array(
    \'posts_per_page\' => 4,
    \'nopaging\' => false,
    \'order\'    => \'ASC\',
    \'orderby\'  => \'rand\',
    \'tax_query\' => array(
        array(
            \'taxonomy\' => \'Count\',
            \'field\' => \'slug\',
            \'terms\' => $f_a,
        )
    )

);

// Put the results in a transient. Expire after 10 minutes.
set_transient( \'county_query\', $akerargs, 10 * MINUTE_IN_SECONDS );

}

ob_start();?>

<div class="container-fluid">

<?php

$akerquery = new WP_Query( $akerargs );

?>

<div class="row">

<?php if ( $akerquery->have_posts() ) {

while ( $akerquery->have_posts() ) {
    $akerquery->the_post();
?>  

   <div class="col-6 mt-4">  

        <a href="<?php the_field(\'county_link\'); ?> ">
                <img src="<?php echo the_field(\'county_img\'); ?>" />
       </a>  

    </div> 

<?php

}

$akerquery->wp_reset_postdata();

} else {

echo \'Oops! Something went wrong.\';

}

?>

</div>
</div>

<?php

return ob_get_clean();

UPDATE

我现在已经尝试了多种可能的解决方案，但仍然不起作用。根据WordPress codex，这是如何实现的：

// Check for transient. If none, then execute WP_Query
if ( false === ( $featured = get_transient( \'foo_featured_posts\' ) ) ) {

      $featured = new WP_Query(
       array(
        \'category\' => \'featured\',
        \'posts_per_page\' => 5
       ));

    // Put the results in a transient. Expire after 12 hours.
    set_transient( \'foo_featured_posts\', $featured, 12 * HOUR_IN_SECONDS );
} ?>

// Run the loop as normal

这就是我现在尝试的：

if(isset($_COOKIE[\'myCookie\']) && $_COOKIE[\'myCookie\'] == $f_a){

    // Check for transient. If none, then execute WP_Query
if ( false === ( $akerargs = get_transient( \'county_query\' ) ) ) {


    $akerargs = array(
    \'posts_per_page\' => 4,
    \'nopaging\' => false,
    \'order\'    => \'ASC\',
    \'orderby\'  => \'rand\',
    \'tax_query\' => array(
        array(
            \'taxonomy\' => \'Count\',
            \'field\' => \'slug\',
            \'terms\' => $f_a,
        )
    )
);


$akerquery = new WP_Query( $akerargs );

    // Put the results in a transient. Expire after 10 minutes.
set_transient( \'county_query\', $akerargs, 10 * MINUTE_IN_SECONDS );
}
// Run the loop as normal

但它仍然运行查询并获取新的帖子，而不是保存在瞬态中首先查询到的4篇帖子。

Set transient name

我正在使用wordpress REST api从网站向应用服务器提供某些数据。此自定义路由用于发送默认图像，一切正常。现在我想使用set\\u transient，我使用了以下代码来实现。 $transient=\'apidata_json_cache\'; $expiration =2*60; // 2 Minutes if(false === ($feed=get_transient($transient))) { echo \'
