Question

我使用Wordpress，更改了一个自定义主题，以显示从网站上找到的脚本的帖子数和估计的阅读时间。我什至还添加了一个选项来打开/关闭它。脚本工作正常...，或者我想。

当我打开Wordpress调试选项以查找主题错误时，此脚本得到了一个提示。但是，我看不到问题。

查看网页时显示的错误：

此帖子包含

注意：未定义变量：发布于   /home/xxxxxx/wordpress.xxxxxx.com/wp-content/themes/xxxxxx/functions.php   在1676行

注意：尝试获取非对象的属性   /home/xxxxxx/wordpress.xxxxxx.com/wp-content/themes/xxxxxx/functions.php   在1676行

我复制并添加到以下脚本的脚本：/functions.php

/*** ADD POST WORD COUNT ***/
function word_count() {
    $content = get_post_field( 'post_content', $post->ID );
    $word_count = str_word_count( strip_tags( $content ) );
    return $word_count;
}

/*** ADD ESTIMATED READING TIME ***/
function reading_time() {
    $content = get_post_field( 'post_content', $post->ID );
    $word_count = str_word_count( strip_tags( $content ) );
    $readingtime = ceil($word_count / 200);
    if ($readingtime == 1) {
      $timer = " minute";
    } else {
      $timer = " minutes";
    }
    $totalreadingtime = $readingtime . $timer;
    return $totalreadingtime;
}

我在/functions.php

中添加的选项

    /* MAIN SETTINGS - Show Entry Word Count Setting */
    $wp_customize->add_setting('swag_main_post_word_count', array(
        'default' => 'swag-main-post-word-count-yes'
    ));
    $wp_customize->add_control('swag_main_post_word_count', array(
        'label' => 'Display Post Word Count',
        'section' => 'swag_main_design',
        'type' => 'select',
        'choices' => array(
            'swag-main-post-word-count-yes' => __('Yes'),
            'swag-main-post-word-count-no' => __('No')
        )
    ));

    /* MAIN SETTINGS - Show Entry Reading Time Setting */
    $wp_customize->add_setting('swag_main_post_read_time', array(
        'default' => 'swag-main-post-read-time-yes'
    ));
    $wp_customize->add_control('swag_main_post_read_time', array(
        'label' => 'Display Post Read Time',
        'section' => 'swag_main_design',
        'type' => 'select',
        'choices' => array(
            'swag-main-post-read-time-yes' => __('Yes'),
            'swag-main-post-read-time-no' => __('No')
        )
    ));

在主题模板文件中：/template-parts/content.php

<?php
    if (isset($swag_main_post_word_count) && $swag_main_post_word_count=='swag-main-post-word-count-yes') {
            echo '<div class="word-count">This post contains ';
            echo '' . word_count() . '';
            echo ' words.</div>';
    }
?>

<?php
    if (isset($swag_main_post_read_time) && $swag_main_post_read_time=='swag-main-post-read-time-yes') {
            echo '<div id="reading-time">This post will take you about ';
            echo '' . reading_time() . '';
            echo ' to read.</div>';
    }
?>

我不认为问题在于添加的选项，但是为了以防万一，我在这里添加了这些选项。我认为问题出在我自己复制的脚本中。这是什么，我该如何解决？

尝试一下：

/*** ADD POST WORD COUNT ***/
function word_count() {
    global $post;
    $content = get_post_field( 'post_content', $post->ID );
    $word_count = str_word_count( strip_tags( $content ) );
    return $word_count;
}

/*** ADD ESTIMATED READING TIME ***/
function reading_time() {
    global $post;
    $content = get_post_field( 'post_content', $post->ID );
    $word_count = str_word_count( strip_tags( $content ) );
    $readingtime = ceil($word_count / 200);
    if ($readingtime == 1) {
      $timer = " minute";
    } else {
      $timer = " minutes";
    }
    $totalreadingtime = $readingtime . $timer;
    return $totalreadingtime;
}

我已将global $post;添加到每个函数中，因此在调用$post->ID时它在范围内。

我无法在Wordpress中跟踪和修复字数统计和读取时间错误
