I have created a page called "Gallery" and created new gallery with 10 images. My page id is 129. I have 10 images in that page id(129).Now my question is, i need a code to fetch those 10 images in wordpress. please anyone help me with a code. Thanks in advance.

推荐答案

使用 get_children

我使用此代码按所选顺序从页面库中提取所有图像.您可以将此代码包含在循环中或单独使用.只需选择适当的 post_parent 代码(参见下面的代码示例).

I used this code to extract all the images from a page gallery in the chosen order. you can include this code in the loop or use it stand alone. just choose the appropriate post_parent code (see bellow the code example).

此示例显示与页面 ID 129 相关联的所有图像，请看:

This example show all images associated to the page id 129, have a look:

    $images = get_children( array( 'post_parent' => 129, 'post_type' => 'attachment', 'post_mime_type' => 'image', 'orderby' => 'menu_order', 'order' => 'ASC', 'numberposts' => 999 ) );

$images 现在是一个对象，它包含所有图像(与帖子 ID 1 相关)及其信息的顺序，就像画廊界面一样.

$images is now a object that contains all images (related to post id 1) and their information ordered like the gallery interface.

    if ( $images ) {

            //looping through the images
            foreach ( $images as $attachment_id => $attachment ) {
            ?>

                        <?php /* Outputs the image like this: <img src="" alt="" title="" width="" height="" /> */  ?>
                        <?php echo wp_get_attachment_image( $attachment_id, 'full' ); ?>

                        This is the Caption:<br/>
                        <?php echo $attachment->post_excerpt; ?>

                        This is the Description:<br/>
                        <?php echo $attachment->post_content; ?>

            <?php
            }
    }

找到您要从中提取图像的帖子 ID 并将其插入到此参数中:'post_parent' => 129

Find the post id you wan to extract images from and insert it into this argument: 'post_parent' => 129

你也可以使用:

'post_parent' => $post->ID如果你想在一个循环中使用 get_children，并从返回的 post id 中获取 post id.

'post_parent' => $post->IDIf you want to use get_children in a loop, and get the post id from the returned post id.

如果您想排除被选为特色图片的图片，我将使用 if 语句检查图片网址是否与特色图片网址相同.

If you want to exclude the image selected as a featured image i would have a if statement check if the image URL is equal to the featured image URL.
