I have a code which returns gallery number 1 with the set of images.
<?php echo photo_gallery(1); ?>
But I need to change number "1" to number "2", "3" and so on with custom fields in every post using this code
<?php the_field('number'); ?>
inside the first code
I need something like this:
<?php echo photo_gallery( <?php the_field('number'); ?> ); ?>
Result:
<?php echo photo_gallery(2); ?>
or
<?php echo photo_gallery(3); ?>
If you really have a custom field number, your code should be the following:
<?php echo photo_gallery( get_the_field( 'number' ) ); ?>
if you want to get the post and then after give the number then follow the code like
$cnt=1;
$queryarry=array( 'post_type' => 'post' ,'posts_per_page' => 9);
while ( have_posts() ) : the_post();
echo photo_gallery($cnt);
$cnt++;
endwhile;
try this

I use a wordpress plugin in which i can add custom data for each category
Now because of some error it doesn't always grab the correct data. to fix that i wrote the following:
<?php if ( in_category( 3 ) ) :
?>
<?php the_field( "categoryselect", "category_3" ); ?>
<?php endif; ?>
Now that works, but is there a way to loop through all my categories with this?
(basicly i need the "3" and the number in "category_3" to loop through all my categories)
i couldnt get it to work, so was going to hard code it, but thought i would ask for help before hardcoding it :P
Thnx in advance
Edit, with help from Ketan, i came to this solution that works for my problem
<?php
$category = get_queried_object();
$testtest = $category->term_id;
if ( in_category( $testtest ) ) :
?>
<?php the_field( "categoryselect", "category_".$testtest ); ?>
<?php endif; ?>
You can do something like this:
<?php
for($i = 0; $i < categories_count; $i++) {
if ( in_category( $i ) ) :
the_field( "categoryselect", "category_".$i );
endif;
}
?>
I am having a loop and that loop has only sticky posts in it. So my logic works like this:
"If Sticky Posts are "EMPTY" break the loop". That code works as expected and looks like this:
<?php //we will get "Sticky Posts" only with this loop and exlude Featured Category
$category = get_cat_ID('Featured');
$col = 1; //Let's create first column
$sticky = get_option( 'sticky_posts' );
$args = array(
/* Add whatever you need here - see http://codex.wordpress.org/Class_Reference/WP_Query */
'paged' => $paged,
'category__not_in' => array($category),
'post__in' => $sticky,
'ignore_sticky_posts' => 1
);
$temp = $wp_query;
$wp_query = null;
$wp_query = new WP_Query($args);
/*Below is IMPORTANT PART*/
if($wp_query->have_posts()):?><?php while ( $wp_query->have_posts() ) :
$wp_query->the_post();if(empty($sticky))break;?>
<div <?php post_class('col'.$col); ?> id="post-<?php the_ID(); ?>">
<?php if ($col == 1) echo '<div class="row">';//If column 1 create first row ?>
<?php if ($col == 2) echo '<div class="row2">';//If column 2 create second row ?>
<h3 class="mytitle"><?php the_title(); ?></h3>
<div class="entry">
<?php if ( has_post_thumbnail() ):?>
<div class="featured_img">
<?php
the_post_thumbnail();
echo '<div class="featured_caption">' . get_post(get_post_thumbnail_id())->post_excerpt . '</div>';
?>
</div><!--/featured_img-->
<?php endif; ?>
<?php // let's enable more link on pages...
global $more;
$more = 0;
?>
<?php the_content(__('Read more','override')); ?>
<div class="clear"></div>
<div class="custom_fields"><?php the_meta(); ?></div><br/>
<p class="postmetadata">
<?php _e('Filed under:','override'); ?> <?php the_category(', ') ?> <?php _e('by','override'); ?> <?php the_author(); ?><br/><?php the_tags(__('Tags:','override'), ', ', '<br />'); ?>
<?php _e('Posted on: ','override'); ?><?php the_time(get_option('date_format')); ?><br/>
<?php if ( comments_open() ) {
comments_popup_link(__('No Comments »','override'), __('1 Comment »','override'), __('% Comments »','override'));}
else {
_e('Comments are disabled!','override');
}
?>
<?php edit_post_link(__(' Edit','override'), __(' |','override'), ''); ?>
</p>
</div><!--/entry-->
</div><!--/post_class-->
<?php /*Enable Two Column Layout*/
if($col==1) {
$col=2;
echo "</div>";
}
else if($col==2) {
$col=1;
echo "</div>";
}
endwhile; ?>
<?php endif; ?><!--END if THE LOOP (Sticky)-->
<?php
$wp_query = null;
$wp_query = $temp;
wp_reset_query();
?>
Now before this working code I tried a different logic that goes like this:
"If NOT EMPTY continue the loop" so now everything in my code stays the same except:if($wp_query->have_posts()):?><?php while ( $wp_query->have_posts() ) :
$wp_query->the_post();if(empty($sticky))break;?> so now that code becomes:if($wp_query->have_posts()):?><?php while ( $wp_query->have_posts() ) :
$wp_query->the_post();if(!empty($sticky))continue;?>
Now this is where i got confused because if(!empty($sticky))continue; part does not work as expected because my loop CONTINUES (returns other posts) even if there are no "Stickies". I thought that loop will STOP if there are no stickies but it is not the case. My var_dump($sticky)
shows this if there are sticky postsarray(1) { [0]=> int(214) } and shows this if there are no stickiesarray(0) { }.
My question is: Why the loop continues to return other posts if using if(!empty($sticky))continue; (i thought it will return ONLY "Stickies" if they exist and return NOTHING if they are not here. )
Thank you!!
First off, let me poit out that your logic doesn't quite agree with your code :).
From what I understand from your code, you want to iterate all posts WP_Query() returned, but only render sticky ones. Your if is inside the wile loop, so you have to check if the current post is sticky or not. However, if(empty($sticky)) doesn't do that. It checks if there are any sticky posts at all. A way to check the current post would be if(is_sticky(the_ID())).
Now, concerning continue:
From the php manual:
continue is used within looping structures to skip the rest of the
current loop iteration and continue execution at the condition
evaluation and then the beginning of the next iteration.
So as you can see, continue doesn't stop the loop, but rather attempts to start the next iteration ignoring the rest of the code for the current step. Which is what you want, if the current post is not sticky, in other words if(!is_sticky(the_ID())).
However, I think you don't really need any check at all, since you already specified that you want WP_Query() to fetch only stickies ('post__in' => $sticky).
See also: this WordPress Answers topic.
I don't know well the wordpress code, but in that code, the $sticky variable is never updated in the while loop. So maybe you have to add $sticky = get_option( 'sticky_posts' ); right before the if condition.
I can’t figure out why this won’t work? I have more than 15 posts but they’re getting cut off the page.
The site: http://gruntsandco.com/
My loop:
<?php $latest = new WP_Query('showposts=15'); ?>
<?php while( $latest->have_posts() ) : $latest->the_post(); ?>
Loopageness
<?php endwhile; ?>
You can try 'posts_per_page' attribute for WP Query.
<?php $latest = new WP_Query('posts_per_page=15'); ?>
<?php while( $latest->have_posts() ) : $latest->the_post(); ?>
Loopageness
<?php endwhile; ?>
If you want to show all posts just set this parametr to -1.
How do you when using custom fields in Wordpress echo just the first value using foreach?
Currently the code is:
<?php for(get_field('venue_event') as $post_object): ?>
<?php echo get_the_title($post_object) ?>
<?php endforeach; ?>
This takes the field from the wordpress page (the field is a link to another page), creates a link to that page using get_permalink but when I want to echo the page title it does it, but then it also echos all other values that are not needed.
If you just want the execute the first iteration of the loop, try this:
<?php foreach(get_field('venue_event') as $post_object): ?>
<?php echo get_the_title($post_object) ?>
<?php break; ?>
<?php endforeach; ?>
Wouldn't it then be easier just to use the first element of the returned array? Maybe Wordpress offers other filters that return the the page's title only.
you can just add
$counter = 0;
<?php for(get_field('venue_event') as $post_object): ?>
$counter++;
if($counter == 1)
{
<?php echo get_the_title($post_object) ?>
}
<?php endforeach; ?>
Seems like the problem with this is the PHP syntax, but no luck in Wordpress forums. This first code block generates a link to the newest post in category "posts."
<?php $my_query = new WP_Query('category_name=posts&showposts=1'); ?>
<?php while ($my_query->have_posts()) : $my_query->the_post(); ?>
<?php the_title(); ?>
<?php endwhile; ?>
This next code block should display the custom field data for the latest post in "posts," with the key of the custom field being "qanda." But it doesn't and it displays nothing.
<?php $my_query = new WP_Query('category_name=posts&showposts=1'); ?>
<?php while ($my_query->have_posts()) : $my_query->the_post(); ?>
<?php echo get_post_meta($post->ID, "qanda", $single = true); ?>
<?php endwhile; ?>
Thanks, Mark
try renaming your second query, otherwise Wordpress will think it is already done
<?php
$my_other_query = new WP_Query('category_name=posts&showposts=1');
while ($my_other_query->have_posts()) : $my_other_query->the_post();
echo get_post_meta($post->ID, "qanda", true);
endwhile;
?>
Apart fromthat $single = true should just be true it looks OK... try var_dump instead of echo and see what you get.
You might need to name it something different. Wordpress might think that you have already done that set of posts, so it is starting at the end, which means it doesn't have anymore posts to process.
