After looking at whats needed for making What's Related editable, I decided to not make a plugin and instead just hack the core files. It ended up with only two small changes to the core files and a new file to edit the what's related entries.
What the changes do is add a link to the What's Related block for story editors entitled "Edit What's Related". The change for this is added to article.php.
Edit the story editor so that if the related block has something in it, then nothing is changed. If its empty then it is filled normally. This requires one addition/change to story.php.
Created a new admin file called related.php which is the editor for the What's Related entries.
The only change in functionality is that once the what's related links are created they are not refreshed on an edit.
Here is what I have done for those who are interested:
-------------------- Addition to article.php -----------------------------------
Right after (row 204 in 1.3.11)
$related = STORY_whatsRelated ($A['related'], $A['uid'], $A['tid']);
Add:
if (SEC_hasRights('story.edit')) {
$related = $related . '<li><a href="' . $_CONF['site_admin_url'] . '/related.php?story=' . $story . '">' . $LANG01[
}
-------------------------End of Addition to article.php ----------------------------
------------------------ Changes to story.php -------------------------------------
Replace: at Line 1130 in 1.3.11
//Get the related URLs
$related = addslashes (implode ("n",
STORY_extractLinks ("$introtext $bodytext")));
With:
if (empty($old_sid)) {
$rel_sid = $sid;
} else {
$rel_sid = $old_sid;
}
$rel_result = DB_query("SELECT related from WHERE sid = ''");
$relA = DB_fetchArray($rel_result);
$related = $relA['related'];
if (empty($related)) {
$related = addslashes (implode ("n",
STORY_extractLinks ("$introtext $bodytext")));
}
