Saving Post Title Permalink To Variable

Hey. I’m making a plugin for my WordPress, and I need the the_content() to also have information about the posts’s title and permalink. To do that, I attempted to add a filter/action (tried both) to the_ID and letting them save the info to a variable. Here’s the code I used for those particular parts:
add_filter('the_ID', 'wooshare_get_title'); // I also tried add_action instead
add_filter('the_content', 'show_wooshare_links');

$wooshare_post_info = Array();

function show_wooshare_links($content)
{
global $wpdb, $wooshare_post_info;
$table_name = $wpdb->prefix . 'wooshare_links';
$query = "SELECT name,url,image,text,title FROM $table_name“;
$buttons = $wpdb->get_results($query, OBJECT);
$insert = ”;
foreach ($buttons as $button)
{
$find = Array(
‘”‘,
‘%title%’,
‘%url%’
);
$replace = Array(
‘%22’,
$wooshare_post_info[‘title’],
$wooshare_post_info[‘permalink’]
);
$button->url = str_replace($find, $replace ,$button->url);
$insert .= ‘url . ‘” class=”wooshare_link” id=”wooshare_’ . $button->name . ‘” title=”‘ . $item->title . ‘”><img src=”‘ . $button->image . ‘” alt=”” class=”wooshare_icon” id=”wooshare_’ . $button->name . ‘_icon” /> ‘ . $button->text . ‘‘;
}
return print_r($wooshare_post_info) . $content . $insert;
}

function wooshare_get_title($id)
{
global $wpdb, $wooshare_post_info;
$table_name = $wpdb->prefix . ‘posts’;
$post = $wpdb->fetch_row(“SELECT post_title,guid FROM $table_name WHERE id = ‘$id'”, OBJECT);
echo $post->post_title;
$wooshare_post_info = Array(‘title’ => $post->post_title, ‘permalink’ => $post->guid);
return print_r($wooshare_post_info) . $id;
}

But the variable stays empty. I can’t echo anything during the_ID so I can’t figure out if it ever gets the data from there or not.
