wordpress插件上没有有效的标题

Question

我已经创建了一个插件，因为某些原因，当我试图上传和激活它通过一个拉链。我收到消息“没有有效的标题”。如果我只是通过ftp删除文件夹，似乎没问题。有什么建议吗？

下面是插件的主要文件：

<?php
/*
 * Plugin Name: Album Gallery
 * Plugin URI: http://vinteractive.co.uk
 * Description: An Album based Slider Gallery.
 * Version: 1.0
 * Author: Vincent Stephens
 * Author URI: http://vinteractive.co.uk
 * License: Do Not Redistribute
 */

define('ALBUM_GALLERY_URL', plugins_url() . '/album-gallery/');
define('ALBUM_GALLERY_ABSPATH', ABSPATH . 'wp-content/plugins/album-gallery/');

define( 'ACF_LITE' , true );
include(ALBUM_GALLERY_ABSPATH . 'custom-fields/acf.php');
include(ALBUM_GALLERY_ABSPATH . 'custom-fields/album-fields.php');
include(ALBUM_GALLERY_ABSPATH . 'custom-post-types/albums-gallery-post-type.php');
include(ALBUM_GALLERY_ABSPATH . 'shortcodes/shortcodes.php');


// Enque Scripts and styles
function album_gallery_scripts() {
wp_register_script('jquery-for-nivo', plugins_url('/js/jquery-1.9.0.min.js', __FILE__), array('jquery'),'1.1', true);
wp_enqueue_script('jquery-for-nivo');
wp_register_script('nivo-slider', plugins_url('/nivo/scripts/jquery.nivo.slider.js', __FILE__), array('jquery'),'1.1', true);
wp_enqueue_script('nivo-slider');
wp_register_script('album-gallery-script', plugins_url('/js/album-gallery.jquery.js', __FILE__), array('jquery'),'1.1', true);
wp_enqueue_script('album-gallery-script');

wp_register_style('album-gallery', plugins_url('/css/album-gallery.css', __FILE__));
wp_enqueue_style('album-gallery');
wp_register_style('nivo-slider', plugins_url('/nivo/nivo-slider.css', __FILE__));
wp_enqueue_style('nivo-slider');
wp_register_style('style', plugins_url('/nivo/style.css', __FILE__));
wp_enqueue_style('style');

// Nivo Theme
wp_register_style('theme-default', plugins_url('/nivo/themes/default/default.css', __FILE__));
wp_enqueue_style('theme-default');
}

add_action( 'wp_enqueue_scripts', 'album_gallery_scripts' );  


?>

短代码文件：

<?php 
    function album_gallery_shortcode() {

        <span class="info_btn"></span>

            $loop = new WP_Query( $args );
            while ( $loop->have_posts() ) : $loop->the_post();

            $album_name = get_the_ID();
            $album_description = get_field('album_description');

                        }
                        $caption = get_field("image_{$i}_caption");

Answer 1

我怀疑这与你的插件包含的高级自定义帖子插件有关。我有一个类似的问题，我解决了它通过移动一个层次的acf文件夹。意思是，我把它放在myplugin/inc/advanced-custom-fields中，而不是myplugin/inc/advanced-custom-fields

而且起作用了。

当然，不要忘记将插件主文件上的路径更改为

include(ALBUM_GALLERY_ABSPATH . 'inc/custom-fields/acf.php');

顺便说一下，我更喜欢这样称呼这个插件：

if( !class_exists('Acf') )
{
    define( 'ACF_LITE' , true ); // Hide it from admin
    include_once('inc/advanced-custom-fields/acf.php' );
}

因为如果用户已经安装了它，您就不希望再次加载它。

Answer 2

当我将ACF包含在插件中时，我也遇到了类似的问题，我花了很长时间才弄明白这一点，尤其是每次创建新插件时，我都会以相同的方式删除插件头模板。

这个问题是由包含的acf.php插件头造成的。从该文件中删除wordpress注释头，无论您从哪个目录级别中包含它，它似乎都安装得很好。
