i am beginner to wordpress theme development.I am developing a theme.I am going through a problem.
In my index.php page i want the most latest post displayed as thumbnail.The second,third and fourth latest post is displayed with only title.I also have five categories.I want the posts displayed category wise.
Now how to do that.Can anyone help me???
Please review the wordpress query before creating a theme first : http://codex.wordpress.org/Class_Reference/WP_Query . With regards to the question. Try this :
// The Query
$args = array('post_type' => 'post', 'posts_per_page' => 5);
$the_query = new WP_Query( $args );
$count = 0;
// The Loop
if ( $the_query->have_posts() ) {
echo '<ul>';
while ( $the_query->have_posts() ) {
$the_query->the_post();
if($count == 0){
the_post_thumbnail();
}else{
echo get_the_title();
}
$count++;
}
echo '</ul>';
} else {
// no posts found
}
/* Restore original Post Data */
wp_reset_postdata();
Cheers!
Please test with this code:
<?php $the_query = new WP_Query('posts_per_page=5&cat=18');
$count = 0;
// The Loop
if ( $the_query->have_posts() ) {
echo '<ul>';
while ( $the_query->have_posts() ) : $the_query->the_post();
if($count == 0){?>
<?php the_post_thumbnail('medium'); ?>
<a href="<?php the_permalink(); ?>" title="<?php printf( esc_attr__( '%s', 'twentyeleven' ), the_title_attribute( 'echo=0' ) ); ?>" rel="bookmark">
<?php the_title(); ?>
</a>
<?php
}else{ ?>
<li class="list">
<a href="<?php the_permalink(); ?>" title="<?php printf( esc_attr__( '%s', 'twentyeleven' ), the_title_attribute( 'echo=0' ) ); ?>" rel="bookmark">
<?php the_title(); ?>
</a>
</li>
<?php
}
$count++;
echo "</li>";
endwhile;
} else {
echo "No Post Found!";
}
/* Restore original Post Data */
wp_reset_postdata();
?>

I am trying to get the image from a category but I cannot retrieve the image.
Today I already learned that I had to use
get_field('product', $term->taxonomy . '_' . $term->term_id);
to fetch content.
But when I use this same method to fetch an image URL from an ACF Field linked to my custom post type category, I do not recieve any values.
This is my code (the var_dump is included):
<?php
$args = array(
'post_type' => 'segments-overview',
'orderby' => 'date', // we will sort posts by date
);
$query = new WP_Query( $args );
$all_terms = [];
if( $query->have_posts() ) :
while( $query->have_posts() ): $query->the_post();
$terms = get_the_terms(get_the_ID(), 'category-segments-overview');
foreach($terms as $term) $all_terms[$term->term_id] = $term;
endwhile;
foreach($terms as $term):
?>
<div class="segments-card">
<div class="img">
<?php
$image = get_field('image', $term->taxonomy . '_' . $term->term_id);
if( !empty( $image ) ): ?>
<img src="<?php echo esc_url($image['url']); ?>" alt="<?php echo esc_attr($image['alt']); ?>" />
<?php endif; ?>
</div>
<div class="content">
<div class="title"><?php echo $term->name; ?></div>
<!-- <?php print_r($term); ?> -->
<a class="button transparent" href="/segments/<?php echo $term->slug; ?>">
<?php echo __('View All','axia'); ?>
</a>
</div>
</div>
</div>
<?php endforeach;
wp_reset_postdata();
else :
?>
<div class="no-posts-found">
<h2>There were no items found</h2>
<h3>Please try a different search</h3>
</div>
<?php
endif;
?>
I use this var_dump to see if everything is fetched:
$image = get_field('image', $term->taxonomy . '_' . $term->term_id);
echo '<pre>';
echo "Image field value:";
var_dump($image);
echo "Category field value:";
var_dump($term);
echo '</pre>';
The only thing is that I do not get the value from my image in my category that is made in ACF.
You can simply get value by passing term object as second parameters.
$image = get_field('image', $term);
Check the docs here: https://www.advancedcustomfields.com/resources/adding-fields-taxonomy-term/
I'm trying to get all related posts on a single template. Posts should have at least one matching tag.
$post_id = $GLOBALS['wp_the_query']->get_queried_object_id();
$tags = get_the_tags( $post_id );
if ($tags && !is_wp_error($tags)) {
$tag_ids = array();
foreach ($tags as $tag) {
$tag_ids[] = $tag->term_id;
}
$args = array (
'tag__in' => $tag_ids,
'post__not_in' => [$post_id]
);
$related_tags_posts = new WP_Query( $args );
wp_reset_postdata();
}
Here is where I'm printing the posts.
<?php while ($related_tags_posts->have_posts()) : $related_tags_posts->the_post() ?>
<?php the_title(); ?>
<?php endwhile; wp_reset_postdata(); ?>
But it's printing just one post from each matching tag. How do I print ALL posts that have matching tags? Not sure what I'm missing.
Please have a look below:
<?php
$tags = wp_get_post_tags($post->ID);
if ($tags) {
echo 'Related Posts';
$first_tag = $tags[0]->term_id;
$args=array(
'tag__in' => array($first_tag),
'post__not_in' => array($post->ID),
'posts_per_page'=>5,
'caller_get_posts'=>1
);
$my_query = new WP_Query($args);
if( $my_query->have_posts() ) {
while ($my_query->have_posts()) : $my_query->the_post(); ?>
<a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>">
<?php the_title(); ?>
</a>
<?php endwhile;
}
wp_reset_query();
}
I hope it would help you out.
Is it possible to find out if only the date/time of a post has been changed or something in the content? The the_modified_date() function covers both and I can't find a way to do a specific check.
The Background: I have a list of posts which will be published in the future and I want to have some feedback for the users if the date or time of an upcoming post changes.
This is my code so far:
<?php
$loop_ls = new WP_Query( $args_ls );
if($loop_ls->have_posts()) : while($loop_ls->have_posts()) : $loop_ls->the_post();
// set date/time variables
$live_date = get_the_date('j.n.');
$live_time = get_the_date('H:i');
?>
<?php if ( get_post_status() == 'future' ) : ?>
<div class="live live--upcoming">
<p><?php _e('Am', 'textdomain') ?> <span class="post-date"><?php echo $live_date; ?></span> <?php _e('um', 'textdomain') ?> <span class="post-time"><?php echo $live_time; ?></span> <?php _e('Uhr', 'textdomain') ?> <?php _e('zum Thema:', 'textdomain') ?>
<br/><span class="post-title"><?php echo get_the_title(); ?></span>
</p>
</div>
<?php elseif ( get_post_status() == 'publish' ) : ?>
<div class="live live--now">
<p><?php _e('Jetzt:', 'textdomain') ?> <span class="post-title"><?php echo get_the_title(); ?></span></p>
<a class="btn btn--default" href="<?php echo get_the_permalink(); ?>"><?php _e('zum LIVE Video', 'textdomain') ?></a>
</div>
<?php endif; ?>
<?php endwhile; endif; wp_reset_postdata(); ?>
OK, I figured out a way to save a creation date for posts published in the future (code below). But I still have the problem, that I can't check if only a posts date/time is modified (not the content).
function wx_add_creation_date_to_live_videos( $post ) {
$post_id = get_the_ID();
$post_type = get_post_type($post_id);
if( $post_type == 'video' && has_term('live', 'video_category') ) {
// If this is a revision, do nothing.
if ( wp_is_post_revision( $post_id ) )
return;
$creation_date = get_the_modified_date('Y-m-d H:i:s', $post_id);
update_post_meta( $post_id, 'creation_date', $creation_date );
}
}
add_action( 'draft_to_future', 'wx_add_creation_date_to_live_videos', 10, 3 );
EDIT:
sometimes you just think too complicated. To check a change on post date/time I changed the code above to this
$orig_publish_date = get_the_date('Y-m-d H:i:s', $post_id);
update_post_meta( $post_id, 'orig_publish_date', $orig_publish_date );
And now I can compare the values of the orig_publish_date with the current publish_date. And that's it.
I have created a new template page and I am displaying custom post type in that page as follows,
<div class="col-sm-4">
<?php $i = 1 ?>
<?php $posts = get_posts(array(
'post_type' => 'astroalbums',
'posts_per_page' => -1
));
foreach ($posts as $post) : start_wp(); ?>
<?php if ($i == 1): ?>
<?php $link = get_permalink($post->ID); ?>
<?php the_title( '<h3 class="entry-title">', '</h3>' );?>
<?php the_post_thumbnail(); ?>
<?php endif; ?>
<?php if($i == 3){$i = 1;} else {$i++;} ?>
<?php endforeach; ?>
My custom post type is "astroalbums" and I want to use it dynamically. I have 4 custom post types. I want to create new page in dashboard and assign the above page template i have created. and each page will call different custom post type.
It will be really great help
Thank you,

You're retrieving the posts correctly, but it's seems that the problem is inside the foreach loop. As the default WordPress loop is not being used, you need to call functions which receive the post id as parameter or use the properties present in the $post object (which is an instance of the WP_POST class) in order to display the data.
One possible solution:
<?php
$posts = get_posts([
'post_type' => 'astroalbums',
'posts_per_page' => 1
]);
?>
<?php foreach( $posts as $post ): ?>
<?php $link = get_permalink( $post->ID ); ?>
<h3 class="entry-title">
<a href="<?php echo esc_url( $link ); ?>" rel="bookmark">
<?php echo get_the_title( $post->ID ); ?>
</a>
</h3>
<a href="<?php echo esc_url( $link ); ?>">
<?php echo get_the_post_thumbnail( $post->ID ); ?>
</a>
<?php endforeach; ?>
