高级自定义字段wordpress图像大小

我正在创建一个带有旋转木马的网站。要加载图像，我使用Wordpress上的高级自定义字段

这是我的代码：

<?php $images = get_field('slides', $post->ID);
// clean_print_r($images);
if (!empty($images)) :
?>
<div class="wide-container">
    <div id="slides">
        <ul class="slides-container">
        <?php for($i = 0; $i < count($images); $i++): ?>
        <!-- slides -->
            <li>
                <img src="<?php echo $images[$i]['img_slide']['sizes']['large'] ?>" alt="" />
            </li>
        <?php endfor; ?>
        </ul>
    </div>
</div>
<?php endif; ?>

与

但这不起作用，并且没有加载图像。

在ACF中，我通过ID调用图像附件，它是一个转发器字段。

我不确定如何使用返回ID执行此操作，但如果您返回URL，您将获得完整图像

编辑： 好的，我用图像ID做了一些测试，看起来你把数组处理搞混了。这适用于单个图像：但应该很容易适应您的中继器

$attachment_id = get_field('slide');
$size = "full";


$image = wp_get_attachment_image_src( $attachment_id, $size );
echo '<img src="' . $image[0] . '">';   

//OR

$image = wp_get_attachment_image( $attachment_id, $size );
echo $image[0]; 

$attachment\u id=get\u字段（“幻灯片”）；
$size=“full”；
$image=wp\u get\u attachment\u image\u src（$attachment\u id，$size）；
回声'；
//或
$image=wp\u get\u attachment\u image（$attachment\u id，$size）；
echo$image[0]；

我之前的回答是关于return:image ID的，这是线程启动程序指定的，但现在我意识到他实际上是在谈论return:object

/*
*  Return value = Object
*  requires ACF 3.3.7+
*/

$image = get_field('image');

var_dump($image);

/*

Data returned will look like this:

显然，原始图像不是大小而是URL，因此更改：

['img_slide']['sizes']['large']

到

你应该没事的

$attachment_id = get_field('slide');
$size = "full";


$image = wp_get_attachment_image_src( $attachment_id, $size );
echo '<img src="' . $image[0] . '">';   

//OR

$image = wp_get_attachment_image( $attachment_id, $size );
echo $image[0]; 

/*
*  Return value = Object
*  requires ACF 3.3.7+

$image = get_field('image');

var_dump($image);
