Why Use Conditional Tags
To do something only whencertain conditions are met
Examples:
Show specific text or images Create custom adverts for specific uses
Designate alternate layouts for certain pages
Using plugins to do this slows down your site

Where can I use Conditional Tags?
Conditions such as is_home with is_front_page, is_single,is_sticky, is_page, is_page_template, is_category,is_tag, is_author, work great in sections such as:
index.php
Header or Footer
Sidebars
the_loop
Comments block
8/8/2019 Wordpress Theme Hacks

Very Specific Conditions
Specify individual pages like is_single('hello') orin_category('5'), is_page_template('contact.php'),is_tag('ipod') or has_tag('ipod'), is_author('john-pratt'),is_date(), is_single(array('my-best-post', 'my-worst-post'))
Specific category and tag pages Specific template pages
Specific archive pages
Specific post ID's

Hacking with Conditional Tags
Do ABC when XYZ Condition is met:
Show my big block of SEO keyword-laden text
By replacing is_home with is_front_page, is_single, is_sticky,is_page, is_page_template, is_category, is_tag,is_author, is_date, is_archive, or is_attachment to makeyour message show up on nearly any WordPress page.

Having Multiple Conditions
Do ABC when XYZ Condition is met,elseif single post page do DEF
Show my home page text blockShow my single post text block instead
In this example we show custom text for the home page, or onsingle pages. If neither condition is met we don't show anycustom text.

Show Everywhere, Except...
Use the concept in reverse to show everywhereexcept where you don't want it...
Show this everywhere!

Prevent Most Comment Spam
Most Spammers use software or scripts that have noreferrer. Require all comments come from a webbrowser to stop the spammers dead!
Add this to your functions.php file:
function check_referrer() { if (!isset($_SERVER['HTTP_REFERER']) ||$_SERVER['HTTP_REFERER'] == ) {
wp_die( __('enable referrers or go away') );}
}add_action('check_comment_flood','check_referrer');
