How to show a content only in front page in WordPress using PHP logic?

Question

I have multiple WordPress site where there is an image of a logo attached to bottom of every page. Now I need it to appear only in the front page and not in the other pages.

What PHP logic and code should I use to solve this problem? I don't want to use the Widget Logic plugins. Just want to edit the PHP logic.

Answer 1

I believe WordPress provides is_home function which returns true if page is set as home/front page. Have a look in here: https://developer.wordpress.org/reference/functions/is_home/

if(is_home()) {
    //my code attaching logo
} 

In WordPress you could actually find a hook/action for a footer display and do it there. You could as well add it site-wide using apache.

Answer 2

You should use is_front_page() function to check if you are on homepage. If you use is_home it will return true on blog page only.

if ( is_front_page() ) {
    # code...
}

Answer 3

Step :1 Check post is home page

if(is_home()) {

}

Step :2 Create Shortcode for the display purpose

function mylogo() {
    if(is_home()) {
        echo '<img src="mylogo.png" alt="">';
    }       
}
add_shortcode('mylogo','mylogo');

Step :3 open footer.php or where even you want to display just use this shortcode,

In php filecode,

do_shortcode('mylogo');

In WYSWYG,

['mylogo']
