When the a loop runs can I have each new post it grabs its own HTML class?

For example

  • Loop runs
  • First item gets class="first"
  • Second item gets class="second"
  • and so on...

Or each post just gets an equivalent numbered class= 1, 2, 3, 4, etc.

I've just been using CSS with nth-child() to target each new item.

index.php (here's the loop call and get_template_part pulls content.php with the loop contents)

```

      <?php $the_query = new WP_Query( array('post_type'=>'post', 'post_status'=>'publish', 'posts_per_page'=>5, 'paged'=>$paged) ); ?> 

      <?php if ( $the_query->have_posts() ) : ?>

      <?php $counter = 1; ?>

      <?php while ( $the_query->have_posts() ) : $the_query->the_post(); ?>

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

```

content.php ( Here's the contents start of the loop where I want to add the class )

```

      <?php include(locate_template('index.php')); ?>

      <?php $counter++; ?>

      <article id="post-<?php the_ID(); ?>" <?php post_class( 'inline-post-' . $counter ); ?>>

```

You could use post_class within the loop.

<?php post_class( 'myclass-here'); ?>

This will add the necessary HTML class="" and WP defaults classes plus your new myclass-here class

You could then use counters within the loop to add a unique suffix to your post class

// Outside the loop initialize your counter
$counter = 1;

.

// Then in the loop
<?php post_class( 'myclass-here-' . $counter ); $counter++; ?>

EDIT

Ok taking into consideration the new information in your question, the way to go is to set a query var and that variable would now be available in your template part.

index.php

Here you would set your query var just before calling get_template_part() and you would increment it just after. You still have to initialize outside the loop the $counter of course. it would look something like this

<?php set_query_var( 'counter', $counter ); ?>
<?php get_template_part( 'content', get_post_format() ); $counter++; ?>

then in your content.php file, you would just have to call your variable $counter

<article id="post-<?php the_ID(); ?>" <?php post_class( 'inline-post-' . $counter ); ?>>

don't increment your $counter in your content.php file and don't include locate_template() either

  • post_class() is what I need, but I hit a few snags. For one this example needs an incrementor or all post will be myclass-here-1 also the loop is in get_template_part, and I can pass it a variable with include(locate_template()) except the counter needs to be outside the loop and include(locate_template('index.php') wont work. I guess index.php isn't a template – winchendonsprings Aug 18 '16 at 21:59
  • You could add a custom filter inside your template file and call the filter before calling get_template_part(), and incrementing $counter just after. If you update your question by posting some code, it will be easier to help you out. Also, why do you want to have a class name with an incremented suffix? couldn't you just use the $post_id as a way of differentiating each class. Better yet, using the post's HTML id tag is the best way to target each post individually. Or maybe you need to know in a predictable way each class beforehand? – bynicolas Aug 18 '16 at 22:25
  • I've added a couple snippets of code. Maybe it will be clearer. Let's say I have a page with ten posts on it. The third post id will be forever changing when new posts are created. If I want to target the third post in the css there's currently no way but with nth-child(3) make sense? @bynicolas – winchendonsprings Aug 19 '16 at 1:05
  • ok, I've edited my answer. you have to set a query var which will be available in your template part. The explanation is here – bynicolas Aug 19 '16 at 4:14

I think this will help you.

if ( have_posts() ) :
    $post_count = 0;
    while ( have_posts() ) : the_post();
    $post_count++;
    $post_classes = 'post-' . $post_count;
    ?>
    <article id="post-<?php the_ID(); ?>" <?php post_class( $post_classes ); ?>>
    <!-- post stuff here.... -->
    </article>
    <?php
    endwhile();
endif;
  • Looks promising. Let's say this is in my index.php file but the loop contents are in content.php. I can't seem to use include(locate_template('index.php')); in content.php to use post_class($post_classes); there. The variables set in index.php won't get carried through to content.php . Too complicated to understand? – winchendonsprings Aug 19 '16 at 0:43
