无法从自定义Wordpress帖子类型获取附件/媒体?
问题描述:
我试图在我插入到管理界面的测试文章中的Wordpress php
代码中获取附加/插入的图像。我点击了“添加媒体”按钮并上传了我的照片并更新了帖子(其中front-page
是自定义帖子类型)。无法从自定义Wordpress帖子类型获取附件/媒体?
(我点击此按钮):
不过,我似乎无法检索与该职位为我的生活相关联的图片。如果我设置了Feature Image
(缩略图),我可以获取该图像,但不能插入图像。以下是我已经试过:
循环通过附件(不走运):
$attachments = query_posts(
array(
'post_type' => 'front-page', // only get "attachment" type posts
'post_parent' => $post->ID, // only get attachments for current post/page
'posts_per_page' => -1 // get all attachments
)
);
foreach($attachments as $attachment) {
echo get_the_ID();
echo wp_get_attachment_image($attachment->ID, 'full');
}
wp_attached_image(文章ID)(不走运):
wp_get_attachment_image($post->ID);
让所有帖子(没运气):
<?php
$args = array(
'post_type' => 'front-page',
'post_mime_type' => 'image',
'numberposts' => -1,
'post_status' => null,
'post_parent' => $post->ID
);
$attached_images = get_posts($args);
echo $attached_images[0];
?>
获得这个职位画廊图像(不走运)
get_post_gallery_images($post->ID);
我真的失去了,为什么我不能检索图像。我已经用尽了几乎所有可以在网上找到的建议,并且想知道它是否与我的自定义帖子类型有关或者是什么?任何帮助,将不胜感激。

我想你错过了带有回声的结果代码(正如我在下面所做的那样)或打印或输出。 我设法与此代码做前一阵子..希望它helps-(在这一个使用的fancybox)
<?php
$attachments = get_posts(array(
'post_type' => 'attachment',
'post_mime_type'=>'image',
'posts_per_page' => -1,
'post_status' => 'any',
'post_parent' => $post->ID)
);
if ($attachments) {
foreach ($attachments as $attachment) {
$src = wp_get_attachment_image_src($attachment->ID, full);
$html = '<a class="fancybox" href="'.$src[0].'">';
$html .= wp_get_attachment_image($attachment->ID, 'gallery-thumb') .'</a>';
echo $html;
}
}
?>

<form id="form1" name="form1" method="post" enctype="multipart/form-data" action="">
<input name="name" type="image" src="resimler/azalt.gif" />
</form>
尝试。
Print_r($ _ Request);你想看的地方。它会工作。

你大概意思是这样(食品法典委员会说,你应该使用get_posts()在这种情况下):

这是我结束了修复它: (评论,以解释我所做的那样)。
<?php
// Argument array to hold parameters for get_post() method.
$args = array(
'post_type' => 'attachment',
'posts_per_page' => -1,
'post_status' => 'any',
'post_parent' => null
);
// Holds the URL of the image.
$image_url = '';
// If we have a thumbnail in the post, use that as the main image.
if (has_post_thumbnail($post->ID)) {
$image_url = wp_get_attachment_image_src(get_post_thumbnail_id($post->ID))[0];
}
// Otherwise, if we have an attachment image, use that as the main image.
else if (get_posts($args)) {
// Simple test to see if we can display attachments from any post.
$attachments = get_posts($args);
if ($attachments) {
$first_photo = $attachments[0];
$image_url = wp_get_attachment_url($first_photo->ID , false);
}
}
// If there are no images, just display the text.
else {
echo "No images";
}
?>
