How to Remove last comma from Gallery Loop?

  • Hello, please tell me how can I remove the last comma in the photo output loop

    it’s my loop code:

    <img class="location__image" src="<?php echo get_the_post_thumbnail_url(get_the_ID() , 'medium_large'); ?>"
             data-hover-slides='<?php $location_gallery_urls = get_field('location_gallery'); ?><?php if ($location_gallery_urls): ?><?php foreach (array_slice($location_gallery_urls, 0, 5) as $location_gallery_url): ?><?php echo esc_url($location_gallery_url); ?>, <?php
        endforeach; ?><?php
    endif; ?>'>
  • Provide the beginning of the loop and information what it is that you are looping over in your foreach statement.

    It requires using a counter, knowing how many items are to be looped over, and knowing when you’ve reached the end.

  • @hube2 Please, could you show me with an example of my code, the fact is that I barely understand what you are talking about, since I don’t understand PHP very well

    <img class="location__image" src="<?php echo get_the_post_thumbnail_url(
    ); ?>"
             $location_gallery_images = get_field("location_gallery");
             if ($location_gallery_images):
                 foreach (
                     array_slice($location_gallery_images, 0, 5)
                     as $location_gallery_image
                     echo esc_url(
                     ); ?>, <?php

    I will be very grateful to you! and even more today I will pray for you in church and light a candle)

  • In your code you are only showing 5 elements, so we know how many will be shown.

    // add a counter at the beginning
    $counter = 0;
    // your loop
    foreach ($items as $item) {
      // output something for this item
      // then
      // increment counter
      // if the counter is <  output a comma
      if ($counter < 5) {
        echo ', ';
