Question

I am adding post thumbnail jquery slider to header part but it’s resulting weird issue. It is somehow not ending while or stop query and so if I will go to single post or page it is keep displaying loop instead of page or post content.

I have tried two different query but none of them stopping to this weird issue.

First Tried

<?php
    query_posts( 'post_status=publish&orderby=rand' );      
    while (have_posts()) : the_post();              

    $title_attr = array(
        'title' => get_the_title(),
        'alt' => get_the_title(),
        'class' => get_the_title(),
    );
    echo '<a href="#post-'.get_the_ID().'" class="scroll theme">';
    the_post_thumbnail('thumbnail',$title_attr);
    echo '</a>';

endwhile; ?>

Than Second Tried

<?php
    $temp = $wp_query;
    $wp_query = null;
    $wp_query = new WP_Query();
    $wp_query->query('post_status=publish&orderby=rand');

    // The Loop
    if ( $wp_query->have_posts() ) : while ( $wp_query->have_posts() ) : $wp_query->the_post();

    $title_attr = array(
        'title' => get_the_title(),
        'alt' => get_the_title(),
        'class' => get_the_title(),
    );
    echo '<a href="#post-'.get_the_ID().'" class="scroll theme">';
    the_post_thumbnail('thumbnail',$title_attr);
    echo '</a>';

endwhile; endif; wp_reset_query();?>

None of these stopping to display loop ( all post like index page) in to single post or page.

I found the solution 🙂

I have added if (have_posts()) before while and end loop with wp_reset_query() and all good now. 🙂

So here is final code if anyone having same problem..

<?php
    query_posts( 'post_status=publish&orderby=rand' );      
    if ( have_posts()): while (have_posts()) : the_post();          

    $title_attr = array(
        'title' => get_the_title(),
        'alt' => get_the_title(),
        'class' => get_the_title(),
    );
    echo '<a href="#post-'.get_the_ID().'" class="scroll theme">';
    the_post_thumbnail('thumbnail',$title_attr);
    echo '</a>';

endwhile; endif; wp_reset_query(); ?>
