How to put code in Loop?

[Doom_87]

Hello. It would be great if someone here could help me because I keep looking and looking but can’t find a solution since I’m new to WordPress. I need to put a plugin’s code inside the theme’s loop but I don’t know where exactly I should place it. I don’t even know which theme file contains the loop. Is it the style.css?

Anyway, the plugin is for displaying featured images inside the posts and it’s this one:

https://wordpress.org/plugins/featured-image/

Until now I have been putting manually the shortcode before each post but I want it to be automated. The creator of the plugin says this is the code that must be placed inside Theme Loop:

<?php if ( function_exists(‘get_featured_img’) ) get_featured_img(); ?>

I tried to contact him but unfortunately he has not replied.

I hope you could help me!
Thanks.

Probably in a single.php template (“single” stands for “single posts”), somewhere in this while statement. More info about the default WordPress loop

<?php if (have_posts()) : while (have_posts()) : the_post(); ?>

// stuff

  <?php if ( function_exists('get_featured_img') ) get_featured_img(); ?>

// stuff

<?php endwhile; ?>

Thanks for answering.
Here’s my single.php so I hope you could point out easier where exactly to put it:

I read through your initial question again, and are now thinking you don’t really need this plugin for what you want.

In your functions.php you should have a line like this: add_theme_support( 'post-thumbnails' );

Then in your single.php one can do something like:

<div class="entry-content entry-single entry-text entry-blog">
<?php
if ( has_post_thumbnail() ) { // check if the post has a Post Thumbnail assigned to it.
  the_post_thumbnail();
}
?>

<?php the_content(); ?> 

</div><!-- .entry-content --> 
?>

If unsure, you can also always look into a barebones theme like Underscores

Thanks for the answer!

Here’s how my single.php looks like:

We will have to start digging a bit deeper: in your single.php file on line-number 14 there is this code-snippet:

<?php get_template_part( 'content', get_post_format() ); ?>

The first piece get_template_part is a WordPress implementation in a custom syntax of the so called “PHP include”.

The second piece get_post_format tells the template engine to look for a file which starts with “content”, then a hyphen and then the name of the “post format“.

If there is no post-format set, then it probably defaults to something like content-single.php.

So the file which is included, and which you will have to look for now is either content-single.php or content-aside.php, content-gallery.php and so on.

Now in this file you can do what I wrote about before: put this snippet in:

<?php
if ( has_post_thumbnail() ) { // check if the post has a Post Thumbnail assigned to it.
  the_post_thumbnail();
}
?>

and in functions.php

add_theme_support( 'post-thumbnails' );
