I am having an issue making a counter variable in a while loop. I am using wordpress. I have 7 pages. I need an id that runs from 1 to 7. I figured that since the query loops through all pages, that a counter would be easy to make but I am proving this to be false. So what I am trying to get would be this

nav_1 nav_2 nav_3

and so on.

So I tried this $counter = 1; class="nav_<?php echo $counter ?>" $counter++;

but all that gives me is nav_1 reapeated 7 times.

Here is the full code

$args = ( array( 'post_type' => 'page', 'posts_per_page' => 7)); if ( is_home() ) {

  $pageQuery = new WP_Query( $args );

  while( $pageQuery->have_posts()) : $pageQuery->the_post();

  $counter = 1; ?>  

  <li class="nav_<?php echo $counter; ?>"><a href="#!/page_about_us"><b><?php the_post_thumbnail(); ?></b><strong></strong><span><?php the_title(); ?></span></a></li><?php

  $counter++;

  endwhile;
  wp_reset_query();

}

You're setting $counter to 1 for every loop.

Set the initial value before the loop begins:

  $counter = 1;
  while( $pageQuery->have_posts() ){ /* etc. ...

I don't know what you mean by that

I figured it out. Thanks, that was the hint I needed

I'm glad you figured it out.

If I was unclear and anyone else was wondering:

  <?php
  // broken:
  while( $i < 5 ){
      $i = 1; //<-- INSIDE loop!
      $i++;
      // this loop will run forever,
      // because, even though $i is incremented
      // at the end of each loop,
      // it's reset to 1 at the beginning of the next.
  }

  // fixed:
  $i = 1; //<-- OUTSIDE loop
  while( $i < 5 ){
      $i++;
      // this loop will stop after 5 iterations
      // (as expected).
  }
