Question

问题：

要解释一下，我正在使用MAMP工作localhost，我正在使用WP ALL IMPORT插件将数据输入wordpress ..我有一个名为BOOK YOUR TRAVEL的主题。它有一个自定义帖子和一个名为“accommodation_images”的特定自定义字段。它将图像ID存储在序列化的整个数组中。很长一段时间，我没有意识到我不必将自己序列化。我找到了类似用途的脚本，并尝试过使用它们。

我设法将所有图片导入并附加插件，然后导入自定义字段“accommodation_images”更难。一旦它到达foreach我就得到空阵。当我评论foreach循环时，只有当我使用以下行

时才会得到一个条目

$atts[] = array("image" =>$attid);

单一条目显然是最后一条，因为它循环通过所有..

但它的格式正确：

a:1:{i:0;a:1:{s:5:"image";s:5:"55079";}}

当数据超过1时，这就是条目的外观。

a:3:{i:0;a:1:{s:5:"image";s:5:"16487";}i:1;a:1:{s:5:"image";s:5:"77726";}i:2;a:1:{s:5:"image";s:5:"77722";}}

unserialize将此数组显示为

Array (
[0] => Array
    (
        [image] => 16487
    )

[1] => Array
    (
        [image] => 77726
    )

[2] => Array
    (
        [image] => 77722
    )

)

以下是我一直在使用的代码

 //This hook is called after WP All Import creates/updates a post meta.
//$pid – the ID of the post/page/Custom Post Type that was just created.
//$attid – the ID of the attachment
//$image_filepath – the full path to the file: C:\path\to\wordpress\wp-content\uploads\2010\05\filename.png

add_action('pmxi_gallery_image', 'update_images_meta', 10, 3);
function update_images_meta( $pid, $attid, $image_filepath ) {
//$attachment = get_post($attid);
// do something with $attachment image

// Get all the image attachments for the post
$param = array(
        'post_parent'       => $pid, 
        'post_type'         => 'attachment', 
        'post_mime_type'    => 'image'
);

$attachments = get_posts($param);

// Initialize the array
$atts = array();

// Fill the array with attachment ID's
  foreach ($attachments as $attachment) {
    //$atts[] = $attachment->ID;
    array_push($atts, array("image" =>$attid));
    //$atts[] = array("image" =>$attid);

 }
    //$serialized = serialize($atts);
    //echo $serialized;

    // unhook this function so it doesn't loop infinitely
    //remove_action( 'save_post', 'update_images_meta', 10 );

    // Update the post's meta field with the attachment arrays
    update_post_meta($pid, 'accommodation_images', $atts);

    // renable save post action
    //add_action( 'save_post', 'update_images_meta', 10 );

}
?>

我需要修复循环以便将其余图像添加到数组中。

Answer 1

（更新）花了很多时间学习php我找到了解决方案.....

答案：答案：2015年11月30日 - 我找到了一种方法来做到这一点，我希望它可以帮助某人。您必须确保您正在测试的图像已生成附件，否则显然不起作用。我强制它并通过设置插件WP ALL IMPORT重命名图像来解决这个问题，因为它上传它们的方式与以前不同，所以它创建了新的附件。祝你好运！

<?php
//This hook is called after WP All Import creates/updates a post      attachment file(s).
add_action('pmxi_gallery_image', 'update_images_meta', 10, 3);
function update_images_meta($pid, $attid, $image_filepath)
{

$attachments = get_children(array(
    'post_parent' => $pid,
    'post_type' => 'attachment',
    'post_status' => 'inherit',
    'order' => 'ASC',
    'post_mime_type' => 'image'
));

//print_r($result);
$atts = array();
// Fill the array with attachment ID's

foreach ($attachments as $attachment) {
    array_push($atts, array(
        "image" => "$attachment->ID"
    ));
}

//echo '<pre>'.print_r($attachments,true).'</pre>'; //for testing
//echo '<pre>'.print_r($attachment,true).'</pre>'; //for testing

// unhook this function so it doesn't loop infinitely
remove_action('save_post', 'update_images_meta', 10);

// Update the post's meta field with the attachment arrays
update_post_meta($pid, 'accommodation_images', $atts);

// renable save post action
add_action('save_post', 'update_images_meta', 10);

}
?>

Answer 2

这是Borisio脚本的更新版本。

<?php

//This hook is called after WP All Import creates/updates a post attachment file(s)
add_action('pmxi_gallery_image', 'add_images_ids_to_meta', 20, 3);
function add_images_ids_to_meta($post_id, $attid, $image_filepath)
{
    $attachments = get_children(array(
        'post_parent' => $post_id,
        'post_type' => 'attachment',
        'post_status' => 'inherit',
        'order' => 'ASC',
        'post_mime_type' => 'image'
    ));

    $atts = array();
    foreach ($attachments as $attachment)
        $atts[] = $attachment->ID;

    // Update the post's meta field with the attachments ids
    update_post_meta($post_id, 'gallery_images_ids', serialize($atts));
}
?>

这将图像ID保存在一个meta字段中。我必须删除那些“ add_action”和“ remove_action”，因为它们破坏了插件。
