Question

我有以下基于this great template的代码用于制作自定义WordPress小部件：

<?php class DRCC_Feat extends WP_Widget {
function dr_post_select_list() {
    $drcc_posts_args = array(
        'post_type' => array( 'post', 'page', 'tribe_events' ),
        'numberposts' => -1,
        'orderby' => 'title',
        'order' => 'ASC'
    );
    $drcc_posts = get_posts( $drcc_posts_args );
    $dr_posts_array = array();
    foreach( $drcc_posts as $post ) {
        $dr_posts_array[$post->ID] = $post->post_title;
    }
    return $dr_posts_array;
}

protected $widget = array(
'description' => 'Custom widget for my client.',
'do_wrapper' => true,
'view' => false,    
'fields' => array(
    array(
        'name' => 'Post to Feature',
        'desc' => 'Enter the IDs of any posts, pages, etc. If more than one, separate with commas.',
        'id' => 'dr_feat_ids',
        'type' => 'select',
        'options' => dr_post_select_list(),
        'std' => ''
    )
)
);

// some more stuff here, but the error is above and the code works when I make 'options' somethings hard-coded.

} ?>

我正在尝试在受保护的dr_post_select_list()数组中调用$widget来动态生成帖子列表，但我在{{1}引用的行中收到错误Parse error: syntax error, unexpected '(', expecting ')'功能在它。就好像它没有意识到它是一个功能。

我在其他地方尝试了这个功能，但它运行正常。我已经尝试将数组公开，并且不会改变任何内容。我已经尝试将函数输出保存在数组中并将变量放在数组中

我觉得我做的事情从根本上是错误的。

tl; dr - 类中数组中调用的方法不运行（或者似乎被识别为方法）。

您错过了函数的结束}。

使用以下内容替换您的代码：

<?php
class DRCC_Feat extends WP_Widget {

    protected $widget = array(
            'description' => 'Custom widget for my client.',
            'do_wrapper' => true,
            'view' => false,
            'fields' => array(
                array(
                    'name' => 'Post to Feature',
                    'desc' => 'Enter the IDs of any posts, pages, etc. If more than one, separate with commas.',
                    'id' => 'dr_feat_ids',
                    'type' => 'select',
                    'options' => 'dr_post_select_list',
                    'std' => ''
                )
            )
    );

    function dr_post_select_list() {
        $drcc_posts_args = array(
            'post_type' => array( 'post', 'page', 'tribe_events' ),
            'numberposts' => -1,
            'orderby' => 'title',
            'order' => 'ASC'
        );
        $drcc_posts = get_posts( $drcc_posts_args );
        $dr_posts_array = array();
        foreach( $drcc_posts as $post ) {
            $dr_posts_array[$post->ID] = $post->post_title;
        }
        return $dr_posts_array;
    }
}

编辑：移动了类内的所有代码，纠正了错误。关于在数组中存储函数的问题，请看一下这篇文章。与JS说的略有不同。 Can you store a function in a PHP array?

私有PHP数组中无法识别函数
