Question

我正在编写一个简单的插件，应该从indesign XML文件和图像文件中导出 - 并从中创建帖子草稿。

我有2个输入。一个用于xml文件，一个用于所有图像：

   <input type="file" name="xmlupload1[]" id="xmlupload[]" multiple="">
   <input type="file" name="imgsupload1[]" id="imgsupload[]" multiple="">

在XML内部有帖子的内容和与这篇文章相关的图像的img标签，如下所示：

   <img href="1_ChrisGardner.jpg" caption="credit: wikipedia"></img>

我想像wordpress一样上传图片，将“caption”属性中的相关标题添加到每个图片中，并将其附加到父帖。

我使用$ _FILES数组和wordpress上传函数进行了很多操作但没有成功......

一些php代码：

$XMLfiles = $_FILES['xmlupload']['tmp_name'];
$post_imgs = $_FILES['imgsupload'];

    foreach ($XMLfiles as $xmlfile){ {

    //CREATE POST FROM XML:

    $xmlstring = file_get_contents($xmlfile);
    $xml = new SimpleXMLElement($xmlstring);

    $content = '';
    $title = $xml->xpath('//h1');
    $post_title = $title[0];

    $excerpt = $xml->xpath('//h2');
    $post_excerpt = $excerpt[0];

    $author = $xml->xpath('//author');
    $post_author = end($author);

    $post_id = create_post($post_title, $post_excerpt);

    $imagetags = $xml->xpath('//img');
    $img_captions = array();
    foreach($imagetags as $imagetag) {
        $img_caption = '';
        $atts = $imagetag->attributes();
        $img_fname = end(explode('/', $image['href']));
        $img_caption = $atts['caption']; 
        $img_captions[$img_fname] = $img_caption;
            unset($imagetag);
    }       

    $paragraphs = $xml->xpath('//p');
    foreach($paragraphs as $p){
        $p->addAttribute('class', 'p1');
    }

    $stories = $xml->xpath('//Story');
    foreach($stories as $story) {
        $content = $content.str_replace( '
        <Story>', '', str_replace( '</Story>', '', $story->asXML()));
    }

    update_post($post_id, $post_title, $post_excerpt, $content, $post_author, $issue_number);

    //ATTACH UPLOADED IMAGES TO POST:
    foreach ($post_imgs['name'] as $key => $value) {
        if ($post_imgs['name'][$key]) {
            $file = array(
            'name'     => $post_imgs['name'][$key],
            'type'     => $post_imgs['type'][$key],
            'tmp_name' => $post_imgs['tmp_name'][$key],
            'error'    => $post_imgs['error'][$key],
            'size'     => $post_imgs['size'][$key]
            );
            $img_caption = $img_captions[urlencode($file['name'])];
            $new_file = wp_handle_upload($file, array( 'test_form' => false ));

            $filename = $new_file['url'];
            $parent_post_id = $post_id;
            $filetype = wp_check_filetype( basename( $filename ), null );
            $wp_upload_dir = wp_upload_dir();

            // Prepare an array of post data for the attachment.
            $attachment = array(
            'guid'           => $wp_upload_dir['url'] . '/' . basename( $filename ), 
            'post_mime_type' => $filetype['type'],
            'post_title'     => preg_replace( '/\.[^.]+$/', '', basename( $filename ) ),
            'post_content'   => '',
            'post_status'    => 'inherit',
            'post_excerpt' => $img_caption
            );

            require_once( ABSPATH . 'wp-admin/includes/image.php' );
            $img_id = wp_insert_attachment( $attachment, $filename, $parent_post_id );
            $img_data = wp_generate_attachment_metadata( $img_id, $filename );

            wp_update_attachment_metadata( $img_id, $img_data );
        }
    }
}

它似乎无法正常工作，也无法创建其他图像尺寸......

请帮忙！在此先感谢!!
