Add a delete post link to another plugin's output. WordPress

jimbob comments:

Hello.
Sorry for not being clear.
Currently I'm using this shortcode:

[display-posts author="Meadow" post_status="publish, private" order="ASC" posts_per_page="100" display-posts title="Default Tasks:"]

The top of the attached picture shows the current output of the shortcode.
The bottom of the attached picture shows what I want the output to be like. I want an extra 'delete' link.

I don't know how to do that. I don't know how to integrate the delete link code (listed in the first link above) into the output of the shortcode.

I guess simply adding this code:

$url = get_bloginfo('url');
if (current_user_can('edit_post', $post->ID)){
echo '<a class="delete-post" href="';
echo wp_nonce_url("$url/wp-admin/post.php?action=trash&post=$id", 'delete-post_' . $post->ID);
echo '">Delete post</a>';
}

into this code:

<?php
/**

* @param $date string, the date part of the output
* @param $excerpt string, the excerpt part of the output
* @return $output string, the modified markup for an individual post
*/

add_filter( 'display_posts_shortcode_output', 'be_display_posts_facebook', 10, 6 );
function be_display_posts_facebook( $output, $atts, $image, $title, $date, $excerpt ) {

// Here's the facebook code we'll be adding to the excerpt
$facebook = 'facebook code goes here';



// First check if an excerpt is included by looking at the shortcode $atts
if ( $atts['include_excerpt'] )
// Now let's rebuild the excerpt with the facebook code at the end
$excerpt = ' - <span class="excerpt">' . get_the_excerpt() . $facebook . '</span>';
else $excerpt = '';

// Now let's rebuild the output. Only the excerpt changed so we're using the original $image, $title, and $date
$output = '<li>' . $image . $title . $date . $excerpt . '</li>';

// Finally we'll return the modified output
return $output;
}

where it says 'facebook code goes here'

should work...

How do I do that?

Oh, and I guess the page should also refresh after someone clicks the 'delete' link, so that the post list can refresh (and not show the deleted post).

Something like this?


add_filter( 'display_posts_shortcode_output', 'delete_post_button', 10, 6 );
function delete_post_button( $output, $atts, $image, $title, $date, $excerpt ) {
global $post;

if (current_user_can('edit_post', $post->ID)){
$delete_button = ' - <a class="delete-post" href="';
$delete_button .= get_delete_post_link( $post->ID );
$delete_button .= '">Delete post</a>';
}

$output = '<li>' . $title . $delete_button . '</li>';

return $output;
}

get_delete_post_link is a better way of handling this:

Hi Hugo,

That's fantastic. It works!

The problem is that I don't want this to show on every call of the [display-posts] plugin.

I only want it on some of them.

I.e. when I have [display-posts include_delete="true"] it should show it, otherwise just show as normal.

Can you do something like:

if ( $atts['include_delete'] )
then
$output = '<li>' . $title . $delete_button . '</li>';

and is there a way to put a class on the delete link, so I can style it later? Something like:

$output = '<li>' . $title <span class="delete">' . $delete_button . '</li>';
