CATEGORY SPECIFIC RSS FEEDS

/*
It is a good idea to offer your readers to subscribe to a particular category of your blog especially if you cover a wide range of categories on your blog.
Simply add /feed to the end of the category URL.

DELAY WHEN POSTS GO TO RSS
*------------------------------------*/
/*
Sometimes you may end up with a grammar or spelling mistake in your article. The mistake goes live and is distributed to your RSS feed subscribers. If you have email subscriptions on your WordPress blog, then those subscribers will get it as well.
Simply add this code in your theme's functions file.
For plugin method and more information, see our detailed guide on how to delay posts from appearing in WordPress RSS feed.

*/
/* VERSINO 1 */
When you publish a blog post, immediately it will send your subscribers notification about the new post via RSS feeds. You can delay posting to RSS feeds for an hour. This can be useful especially in case if you forget to check for broken links or typos before publishing your posts.

EXPORT EMAIL OF USER SUBMITTED COMMENTS
*------------------------------------*/
/*
Execute the below SQL query against your database to export all the user submitted email addresses with no duplicates. This can be helpful for building your email list.
SELECT DISTINCT comment_author_email FROM wp_comments;
Following the implementation of GDPR, this needs to be exclusively specified and agreed to as part of your privacy policy. You also need to double opt-in and users which are added to your mailing list in this way.
*/
/*------------------------------------*
DISABLE HTML IN COMMENTS
*------------------------------------*/
/*
Spammers used to submit tons of HTML links while commenting, which can have negative impact in bringing organic traffic to your website. Simply open functions.php and insert the following code to disable HTML elements in comments.
// This will occur when the comment is posted
function plc_comment_post( $incoming_comment ) {
// convert everything in a comment to display literally
$incoming_comment['comment_content'] = htmlspecialchars($incoming_comment['comment_content']);
// the one exception is single quotes, which cannot be #039; because WordPress marks it as spam
$incoming_comment['comment_content'] = str_replace( "'", '&apos;', $incoming_comment['comment_content'] );
return( $incoming_comment );
}
// This will occur before a comment is displayed
function plc_comment_display( $comment_to_display ) {
// Put the single quotes back in
$comment_to_display = str_replace( '&apos;', "'", $comment_to_display );
return $comment_to_display;
/*------------------------------------*
SEPARATE COMMENTS AND TRACKBACKS
*------------------------------------*/
/*
By default, WordPress combines both comments and trackbacks together. Separating both can make the things look more organized.
Step 1: Find the below code in the comments.php file.
<?php foreach ($comments as $comment) : ?>
Paste the below code after it.
<?php $comment_type = get_comment_type(); ?>
<?php if($comment_type == 'comment') { ?>
Step 2: Then, look for the below code
<?php endforeach; /* end for each comment */ ?>
Paste the below code before it
<?php } else { $trackback = true; } /* End of is_comment statement */ ?>
Step 3: Then, look for the following code
<?php else : // this is displayed if there are no comments so far ?>
Paste the below code before it
<?php if ($trackback == true) { ?>
<h3>Trackbacks</h3>
<ol>
<?php foreach ($comments as $comment) : ?>
<?php $comment_type = get_comment_type(); ?>
<?php if($comment_type != 'comment') { ?>
<li><?php comment_author_link() ?></li>
<?php } ?>
<?php endforeach; ?>
</ol>
<?php } ?>
*/
/*------------------------------------*
PREVENT COMMENT SPAN
*------------------------------------*/
/*
Instead of marking comments as spam each time, you can block the spammers outright from publishing comments on your blog. The below code will look for HTTP referrer and automatically blocks the comment if the referrer is not valid.
Add the below code in the functions.php file.
*/
function check_referrer() {
if (!isset($_SERVER['HTTP_REFERER']) || $_SERVER['HTTP_REFERER'] == “”) {
wp_die( __('Please enable referrers in your browser, or, if you're a spammer, bugger off!') );
}
}
add_action('check_comment_flood', 'check_referrer');
/*------------------------------------*
EDIT COMMENTS FROM FRONT END
*------------------------------------*/
/*
Add actionable buttons on published comments
actionable buttons
Often, you might want to edit some published comments. By default, if you are logged in to your site, on top of every comment you published you can see a link where you can click to edit the comment. Additionally, how about marking a comment as spam or even delete it from your blog post itself? This is one of those WordPress tricks which can really help you maintain your website easier and faster, because you're doing everything from the frontend.
Add the below code to functions file.
*/
function delete_comment_link($id) {
if (current_user_can('edit_post')) {
echo '| <a href="'.admin_url("comment.php?action=cdc&c=$id").'">del</a> ';
echo '| <a href="'.admin_url("comment.php?action=cdc&dt=spam&c=$id").'">spam</a>';
}
}
/*
Then, add the below code snippet to comments.php file.
delete_comment_link(get_comment_ID());

*------------------------------------*/
/*
Highlight author comments
To highlight the author comments, find the following code in your CSS file.
*/

/*------------------------------------*
DISPLAY MOST RECENT COMMENTS
*------------------------------------*/
/*
Display most recent comments
Add the following changes anywhere in your theme where you want to display the 5 most recent comments. As with other WordPress tips we've mentioned here, you can change the number 5 to show more or less comments as needed.
