multiple loops, if first post in loop 1 matches first post in loop 2, skip…

  • I have my index set up with two loops. The first loop shows the four latest posts from categories 3, 4, and 5. The second loop shows posts from categories 1 and 3. The problem is that every now and then, a post will show up as the first post in loop 1 which will match the first post in loop 2. In cases like these, I would like the first post in loop 1 to not show. I’ve attempted this (incorrectly) in my code below with $first_post = $id == 1; and if( $post->ID == $first_post ) continue;. If anyone can help me out with this, I would really appreciate it.

    <?php get_header(); ?>

<div id="page">
<div class="content">
   <?php
    $first_post = $id == 1;
/************************* LOOP 1 Four Posts in a Carousel **********************/
    query_posts('cat=3,4,5&showposts=4');
	while (have_posts()) : the_post();
	if( $post->ID == $first_post ) continue;
	$Thumbnail = get_post_meta($post->ID, 'Thumbnail', $single = true);
   ?>
			<div id="carousel-post" style="border-right: 1px solid #dddddd; display:inline; float:left; height:170px; margin:0 0 20px 0; padding:5px; width:145px;">
			<center><div class="carousel-thumb"><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><img class="blog-avatar" width="100" height="100" src="<?php echo get_post_meta($post->ID, "Thumbnail", true);?>" /></a></div></center>
			<h2 style="font-size:1.3em; margin:5px 0 0 0"><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php if (strlen($post->post_title) > 60) {
			echo substr(the_title($before = '', $after = '', FALSE), 0, 60) . '...'; } else {
			the_title();
			} ?></a></h2>

    Thanks esmi. That’s what I based my code on actually so I’m familiar with it. Basically, I just need to know what variable I should use to target the first post and omit it if necessary.

    How about replacing if( $post->ID == $first_post ) continue; with:

    $check = get_posts('cat=3&numberposts=1');
if ( $check[0]->ID == $post->ID ) continue;

    Thanks esmi! The code works; however, I’m confused as to HOW it works because in your code it says (‘cat=3&numberposts=1’). Can you explain so I can know for future reference?

    To be more specific, I don’t understand why you only put cat=3 and not the other categories, yet it still works for all first posts.

    $check = get_posts('cat=3&numberposts=1');

    Get 1 (the latest) post in category id 3.
    The only potential duplication is within category 3 based on the details you gave above (Loop 1: cats 3,4 & 5 – Loop 2: cats 1 &3)

    if ( $check[0]->ID == $post->ID ) continue;

    If the id of this post matches the post you’re about to display, the the post you’re about to display must be the latest post in Category id 3). So skip it and move onto the next post (continue:) because this post will be shown in the second loop.

    Does that make sense?

    Yes, I think I understand. Thank you.

    I love it!

    I am playing with it for a while now to get this check to skip the first 2 posts, i can′t get it done.

    Can you tell me how to skip the first 2 posts and continue.

    thanks

    @mediabros

    assuming anything else is the same othersise:

    if this line:
    $check = get_posts('cat=3&numberposts=1');
    skips 1 post;

    then this line:
    $check = get_posts('cat=3&numberposts=2');
    should skip 2 posts.

    I had the same problem. Thankfully the problem got sorted.

    That was what i tried indeed, but it didn’t work out for me

    This is my code

    <?php while (have_posts()) : the_post(); ?>
<?php $check = get_posts('numberposts=1'); ?>
<?php if ( $check[0]->ID == $post->ID) continue; ?>

    I tried

    <?php while (have_posts()) : the_post(); ?>
<?php $check = get_posts('numberposts=2'); ?>
<?php if ( $check[0]->ID == $post->ID) continue; ?>

    but the this is still only skipping the first post and showing the second.

    When i change it to

    <?php while (have_posts()) : the_post(); ?>
<?php $check = get_posts('numberposts=2'); ?>
<?php if ( $check[1]->ID == $post->ID) continue; ?>

    It will skip the second post but show the first post

    so i figured out to do it like this.

    <?php while (have_posts()) : the_post(); ?>
<?php $check = get_posts('numberposts=2'); ?>
<?php if ( $check[0]->ID == $post->ID | $check[1]->ID == $post->ID) continue; ?>

    That is working for me.

    @arpankar,

    How did you solved your problem?
