如何从使用自定义查询获取的 wordpress post_content 中删除所有视觉作曲家 shortcode/tags

Question

我正在开发一个 Web 服务 (API)，我正在其中获取结果 WP_query() 函数并以 JSON 格式解析它。它将进一步用于 android 应用程序。问题是我得到的 post_content 查询是由视觉作曲家组成的，整个内容都是像

这样的标签形式

[VC_ROW][/VC_ROW][VC_COLUMN]some text[/VC_COLUMN] etc.

我想 remove/strip 从内容中提取所有这些短代码，并仅从中检索纯文本。有没有视觉作曲功能可以实现这个东西

<?php
require('../../../wp-load.php');
require_once(ABSPATH . 'wp-includes/functions.php');
require_once(ABSPATH . 'wp-includes/shortcodes.php');
header('Content-Type: application/json');

$post_name = $_REQUEST['page'];

if($post_name!=''){
    if($post_name=='services') {

    $args = array(
        'post_parent' => $page['services']['id'],
        'post_type'   => 'page', 
        'post_status' => 'published' 
    ); 
    $posts = get_children($args);
    foreach($posts as $po){
        $services_array[] = array('id'=>$po->ID,'title'=>$po->post_title,'image'=>get_post_meta($po->ID, 'webservice_page_image',true),'description'=>preg_replace("~(?:\[/?)[^/\]]+/?\]~s", '', $po->post_content));
    }

    $post = array(
        'status'=>'ok', 
        'services'=>$services_array
    );
    echo json_encode($post);
}
}
?>

Answer 1

在这里，您可以尝试轻松地在数组中添加一些您需要的短代码，也可以通过以下代码删除所有短代码。

$the_content = '[VC_ROW][VC_COLUMN]some text1[/VC_COLUMN] etc.[/VC_ROW][VC_COLUMN_INNTER width="1/3"][/VC_COLUMN_INNTER]';

$shortcode_tags = array('VC_COLUMN_INNTER');
$values = array_values( $shortcode_tags );
$exclude_codes  = implode( '|', $values );

// strip all shortcodes but keep content
// $the_content = preg_replace("~(?:\[/?)[^/\]]+/?\]~s", '', $the_content);

// strip all shortcodes except $exclude_codes and keep all content
$the_content = preg_replace( "~(?:\[/?)(?!(?:$exclude_codes))[^/\]]+/?\]~s", '', $the_content );
echo $the_content;

您想保留一些您不能使用 strip_shortcodes() 的简码。

最佳方案，已解决。
只需将以下代码添加到文件 wp-includes/rest-api.php，在底部：

/**
 * Modify REST API content for pages to force
 * shortcodes to render since Visual Composer does not
 * do this
 */
add_action( 'rest_api_init', function ()
{
   register_rest_field(
          'page',
          'content',
          array(
                 'get_callback'    => 'compasshb_do_shortcodes',
                 'update_callback' => null,
                 'schema'          => null,
          )
       );
});

function compasshb_do_shortcodes( $object, $field_name, $request )
{
   WPBMap::addAllMappedShortcodes(); // This does all the work

   global $post;
   $post = get_post ($object['id']);
   $output['rendered'] = apply_filters( 'the_content', $post->post_content );

   return $output;
}

Answer 3

我把它带到了某个地方并对其进行了一些更新，以便更好地工作:)。在 functions.php 中添加此功能：

/** Function that cuts post excerpt to the number of a word based on previously set global * variable $word_count, which is defined below */

if(!function_exists('kc_excerpt')) {

  function kc_excerpt($excerpt_length = 20) {

    global $word_count, $post;

    $word_count = $excerpt_length;

    $post_excerpt = get_the_excerpt($post) != "" ? get_the_excerpt($post) : strip_tags(do_shortcode(get_the_content($post)));

    $clean_excerpt = strpos($post_excerpt, '...') ? strstr($post_excerpt, '...', true) : $post_excerpt;

    /** add by PR */

    $clean_excerpt = strip_shortcodes(remove_vc_from_excerpt($clean_excerpt));
    /** end PR mod */

    $excerpt_word_array = explode (' ',$clean_excerpt);

    $excerpt_word_array = array_slice ($excerpt_word_array, 0, $word_count);

    $excerpt = implode (' ', $excerpt_word_array).'...'; echo ''.$excerpt.'';

  }
}

然后你正常调用它 kc_excerpt(20); 它会 return 正常 post_content/excerpt

Answer 4

I want to remove/strip all these shortcode from the content and retrieve only plain text from it.

对我有用的解决方案：

$content = strip_tags( do_shortcode( $post->post_content ) );

do_shortcode 触发所有视觉作曲家短代码，因此 returns html+text;

strip_tags 删除所有 html 标签和 returns 纯文本。

如何从 wp 中删除可视化编辑器 post: ie11=] 另外 WP post 删除短代码和 html 标签。

while($posts->have_posts()) {
      $postContent = get_the_content();
      //Remove html tags. and short code 
      $postContent = strip_tags( do_shortcode( $postContent ) );
      //Remove visual composer tags [vc_column] etc
      $postContent = preg_replace( "/\[(\/*)?vc_(.*?)\]/", '', $postContent );
}

Answer 6

从 wordpress api 查找源代码，我做了一个从内容中删除一些短代码的功能。所以这是结果：

function removeShortcode($content, $shortcodeList){
  preg_match_all('@\[([^<>&/\[\]\x00-\x20=]++)@', $content, $matches);
  $tagnames = array_intersect($shortcodeList, $matches[1]);
  if(empty($tagnames)){
    return $content;
  }
  $pattern = get_shortcode_regex($tagnames);
  preg_match_all("/$pattern/", $content, $matchesTags);
  foreach ($matchesTags[0] as $key => $value) {
    $content = str_replace($value, $matchesTags[5][$key], $content);
  }
  return $content;
}

示例：

$content = "<p>Hi, this is a [example]<b>example</b>[/example]. [end]</p>";
$shortcodesToRemove = ["example", "end"];
echo removeShortcode($content, $shortcodesToRemove);

Answer 7

foreach($posts as $po){
    $services_array[] = array('id'=>$po->ID,'title'=>$po->post_title, 'description'=>do_shortcode($po->post_content));
}

你应该试试这个。
