Question

我目前正在制作一个Wordpress插件，我几乎可以使用它。它是一个自定义帖子类型，包含默认值，列和自定义字段（高级自定义字段）。

function newplugin_install() {

$new_post = array( 
    'post_title' =>     'One Once Un Single',
    'post_content' =>   '(FIRST). Lorem ipsum dolor set elit...',
    'post_status' =>    'publish',
    'post_type' =>      'exhibitor'
    // INSERT default.png here somehow
);


//SAVE THE POST
$pid = wp_insert_post($new_post);


}

我想根据特色图片或基于ACF图像类型添加默认图像。我不知道从哪里开始。

非常感谢，

1-首先，如果您需要插入帖子

注意：如果你知道帖子ID并且你不需要插入新的，你可以跳过第二步

$new_post = array(
    'post_title'    =>  $title,
    'post_content'  =>  $outputValue,
    'post_category' =>  array($_POST['cat']),  // Usable for custom taxonomies too
    'tags_input'    =>   $tags_keywords,
    'post_status'   =>  'publish',           // Choose: publish, preview, future, draft, etc.
    'post_type' =>  'post'  //'post',page' or use a custom post type if you want to
    );

    //SAVE THE POST
  $pid = wp_insert_post($new_post);

2-秒插入图像

//代码：如果你想从网址插入图片

if(isset($_POST['the_img_link']) && $_POST['the_img_link'] != ''){
    $image_url = $_POST['the_img_link'];
    basename($image_url);
    $upload_dir = wp_upload_dir();
    $image_data = file_get_contents($image_url);
    $filename = basename($image_url);
    if(wp_mkdir_p($upload_dir['path'])){
    $file = $upload_dir['path'] . '/' . $filename;
    }else{
    $file = $upload_dir['basedir'] . '/' . $filename;
    }
    file_put_contents($file, $image_data);
    $wp_filetype = wp_check_filetype($filename, null );
    $attachment = array(
        'post_mime_type' => $wp_filetype['type'],
        'post_title' => sanitize_file_name($filename),
    'post_content' => '',
    'post_status' => 'inherit'
    );
    $attach_id = wp_insert_attachment( $attachment, $file, $pid );
    require_once(ABSPATH . 'wp-admin/includes/image.php');
    $attach_data = wp_generate_attachment_metadata( $attach_id, $file );
    wp_update_attachment_metadata( $attach_id, $attach_data );
    set_post_thumbnail( $pid, $attach_id );
}else{
    // $other_attach_id is any previous added attached image
    // you want it to be a default image
    set_post_thumbnail( $pid, $other_attach_id )
}

//代码：如果你想插入你的电脑的图像

if ($_FILES) {
    foreach ($_FILES as $file => $array) {
        $attach_id = wp_insert_attachment( $attachment, $file, $pid );
        require_once(ABSPATH . 'wp-admin/includes/image.php');
        $attach_data = wp_generate_attachment_metadata( $attach_id, $file );
        wp_update_attachment_metadata( $attach_id, $attach_data );
        set_post_thumbnail( $pid, $attach_id );
    }
}else{
    // $other_attach_id is any previous added attached image
    // you want it to be a default image
    set_post_thumbnail( $pid, $other_attach_id )
}

如何在帖子中添加默认图像（或图像）？
