Logical condition that the page - home page is If ... Else ...

When we built a theme it is always better to have the warning possible page. 

For simplicity above all. When returns to a website after a while there is much more easily.

So for example, instead of a different footer to the home page and interior pages. We can only use conditions, such as:

 






 
If this is the home page:

Do this: ....

If this is not the home page

Do this: ... ..

If not you need to create a new file, for example footer-home.php. For maintenance or modifications it complicates our lives and we can create errors by changing one but not the other.

Example:

<?php
if ( is_front_page() && is_home() ) {
  // Default homepage
} elseif ( is_front_page() ) {
  // static homepage
} elseif ( is_home() ) {
  // blog page
} else {
  //everything else
}
?>


If you want to code with HTML:

 <?php if ( is_front_page()) : ?>

 <img src="<?php echo get_stylesheet_directory_uri(); ?>/images/logo-accueil.png" width="326" height="184" alt="Logo"/>

 <?php endif; ?>
If this is not the home page (must be added the exclamation point)


 <?php if ( !is_front_page()) : ?>

 <img src="<?php echo get_stylesheet_directory_uri(); ?>/images/logo-diane-limoges-inner-en.png" width="263" height="162" alt="Logo Diane Limoges"/>

 <?php endif; ?>
Conditions in the footer

I have not done further research but if it does not work in the footer, you must reset the Global value if you use this function in the footer:

wp_reset_query ()


<?php wp_reset_query(); ?>
<?php if ( is_front_page()) : ?>

<p>Ça marche</p>

<?php endif; ?>
