How to list all external URLs that I have posted on my WordPress blog?

Question

I want to list all the external links of my posts in a single place/file. How can I achieve this?

• Is it possible to achieve this via a plugin?

• Is it possible to achieve this with a built-in wordpress api?

• Is it possible to achieve this via some free 3rd party tool?

What approach should be followed for achieving this?

Answer 1

The above code had pagination concerns when I wanted to parse each and every page. So, building on the above, plus a kicker to search for links without 'nofollow' attributes, I came up with the following:

<ol>
<?php 

global $post;

//Write Site URL below.
//Don't write http:// or anything like that. just domain.com or domain.net
$_site_url = 'google.com';

$args = array(
    'posts_per_page'   => 9999999999,
    'offset'           => 0,
    'category'         => '',
    'category_name'    => '',
    'orderby'          => 'ID',
    'order'            => 'DESC',
    'include'          => '',
    'exclude'          => '',
    'meta_key'         => '',
    'meta_value'       => '',
    'post_type'        => 'post',
    'post_mime_type'   => '',
    'post_parent'      => '',
    'author'       => '',
    'author_name'      => '',
    'post_status'      => 'publish',
    'suppress_filters' => true 
);
$myposts = get_posts( $args );
foreach( $myposts as $post ) : setup_postdata($post); 

  //Get Post content
  $_post_content =  get_the_content();

  $site_parts = explode('.',$_site_url);
  $site_suffix = '.'.$site_parts[1];

  //Using regular expression to match hyperlink
  preg_match_all('|<a.*(?=href=\"([^\"]*)\")[^>]*>([^<]*)</a>|i', $_post_content, $match);

  foreach($match[0] as $link){
    //Filtering out internal links
    $parts = explode($site_suffix, $link);
    $domain = explode('//',$parts[0]);
    //echo $domain[1];
    if ($domain[1] != 'www.'.$site_parts[0] && $domain[1] != $site_parts[0] && strpos($link, 'nofollow') === FALSE){
        echo '<li><a href="'.get_permalink($post->ID) . '">' . get_the_title() .'</a>,&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'. $link.'</li>';
    }
  }

endforeach;
wp_reset_postdata(); 

?>
</ol>

Create a page with the name links. Pages >> Add New into your wordpress panel. Just name it links and publish. See below.

Now go to your theme folder wp-content\themes\YOUR_ACTIVE_THEME_FOLDER and create a page page-links.php.

And paste this code in page-links.php

<?php  

$the_query = new WP_Query(array('post_type' => 'post'));
while($the_query->have_posts()):
    $the_query->the_post();
    $_post_id = get_the_id();

//Write Site URL below.
//Don't write http:// or anything like that. just domain.com or domain.net
$_site_url = 'google.com';

//Getting Post content
$_post_content =  get_post_field( 'post_content', $_post_id);


$site_parts = explode('.',$_site_url);
$site_suffix = '.'.$site_parts[1];
//Using regular expression to match hyperlink
preg_match_all('|<a.*(?=href=\"([^\"]*)\")[^>]*>([^<]*)</a>|i', $_post_content, $match);

foreach($match[0] as $link){
    //Filtering out internal links
    $parts = explode($site_suffix, $link);
    $domain = explode('//',$parts[0]);
    //echo $domain[1];
    if ($domain[1] != 'www.'.$site_parts[0] && $domain[1] != $site_parts[0]  ){
        echo $link.'<br>';
    }
}

endwhile;
    wp_reset_postdata();
?>

Now you need to make a change in the code above.

    //Write Site URL below.
//Don't write http:// or anything like that. just domain.com or domain.net
$_site_url = 'google.com';

In place of $_site_url = 'google.com'; write your own domain. Make sure it's without www and without http://

Have a look at the page.

NOTE: All pages that are linked internally are avoided, only pages that are linked to external sites will be visible.

Customize code for the needful.
