Wordpress custom field - css in loop - php

I try to insert the value of a custom field in a background-image property ( therefore not in img src="..."').
In my category.php; I can display the custom field linked to each post; but when I put the variable in my style ( inline css ), wordpress always displays the same image.
The code :
<?php
// The Loop
while ( have_posts() ) : the_post(); ?>
<div class="interview">
<a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>">
<?php $photo_interview = get_field('photo_apercu', $post->ID); ?>
<?php echo $photo_interview; ?>
<?php the_title(); ?>
<style type="text/css">
.photo_interview {
background-image: url(<?php echo $photo_interview; ?>);
}
</style>
<div class="photo_interview"></div>
</a>
</div>
<?php endwhile;
else: ?>
<?php endif; ?>
Any idea ? My page here : http://www.overso.me/category/interview/

Your code should be this:
<?php
// The Loop
while ( have_posts() ) : the_post(); ?>
<div class="interview">
<a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>">
<?php $photo_interview = get_field('photo_apercu', $post->ID); ?>
<?php echo $photo_interview; ?>
<?php the_title(); ?>
<!-- You don't need style tags if you only want to set the background image -->
<div style="background-image: url(<?php echo $photo_interview; ?>)"></div>
</a>
</div>
<?php endwhile;
else: ?>
<?php endif; ?>

For what I can see you haven't set the global $post, so get_field do not know which is needed to display. in this case it will be better to use the_ID() to get the current post ID inside the while loop.
Cheers

trying to insert php into img src attribute to display featured image on custom post archive page in Wordpress

The image is set to return a URL in the Custom Fields Plugin however it is just coming up with img src Unknown, everything else works on the page except this... code is as follows: Thanks in advance for any help!
<?php get_header(); ?>
<?php
$args = array(
'post_type' => 'artists',
);
$query = new WP_Query( $args );
?>
<section class="row artists">
<?php if ( $query->have_posts() ) : while ( $query->have_posts() ) : $query->the_post(); ?>
<div class="col-sm-12 col-md-6 col-lg-3">
<a href="<?php if( get_post_field('artist_website') ) { ?>
<?php echo $artist_website; ?>
<?php } else { the_permalink(); } ?>">
<img src="<?php get_post_field('artist_feature_image'); ?>" alt="<?php echo the_title() ; ?>">
<p><?php echo the_title() ;?></p>
</a>
</div>
<?php endwhile; endif; wp_reset_postdata(); ?>
</section>
<?php get_footer(); ?>
The problem is that get_post_field('artist_feature_image') only return the image.
You need to display it with "echo"
<img src="<?php echo get_post_field('artist_feature_image'); ?>" />
And don't do echo the_title() ;, because the_title() is already doing an echo on get_the_title();
function the_title() {
echo get_the_title();
}
So if you want to display it you just have to do: the_title();

ACF Wordpress styling custom fields

I have an issue with styling each field of ACF in .php file.
<?php the_field('service_section_title'); ?>
<?php the_field('service_section_description'); ?>
Learn more
<?php if( have_rows('services') ):
while ( have_rows('services') ) : the_row();
$image = get_field('service_icon'); if( !empty($image) ):
<img src="<?php echo $image['url']; ?>" alt="<?php echo $image['alt']; ?>" />
get_field('service_title');
get_field('service_description');
endwhile; else : endif; ?>
How exactly I should put HTML to wrap my
get_field('service_title');
get_field('service_description');
And Image field;
For example:
<p class="text-faded">?php get_field('service_description');?>
</p>
How to wrap php with html in a correct way (not breaking the php code with php and then interrupting again)
Here is what I suggest you do:
<?php if (have_rows('repeater')): ?>
<?php while (have_rows('repeater')): the_row(); ?>
<?php
$variable = get_sub_field('variable');
?>
<div class="repeater-item">
<div class="variable-item">
<?php echo $variable; ?>
</div>
</div>
<?php endwhile; ?>
<?php endif; ?>
All you do after this is style everything inside div class="variable-item" and then you can style anything in there.

Show next post after 'do_not_duplicate[]' prevents one from showing

I'll try to word this the best I can:
My blog homepage has 4 feeds of "Latest from: (a category)" fed by 4 different categories, each showing 2 posts. I discovered the do_not_duplicate method and used that to prevent any of them from showing up twice (since the authors use multiple categories on each post to populate our blog). This works great, but here is my next issue:
If a post has multiple categories that populate the home page, it will post in just one category and not duplicate (as wanted), but the other category it is in now only shows just 1 post, where I'd like it to show 2. Since the 2nd 'missing' post is the duplicate, not be shown, I'm wondering how I can show the next (3rd) post in that category, if the duplicate is being hidden.
Here is my current code:
<!-- BEGIN WP PHP BLOG INSERT-->
<?php query_posts('category_name=campuses&showposts=2'); //Get 2 most recent posts from category with slug campuses ?>
<h2 class="cat"><?php if (have_posts()) single_cat_title("Latest from: ", true) //if there are posts in the category, display the category name in an H2 ?></h2>
<?php if (have_posts()) while (have_posts()) : the_post(); $do_not_duplicate[] = $post->ID; // prevents the post from showing up twice on home page?>
<?php if ( has_post_thumbnail()) : //check to see if the post has a featured image ?>

Not sure if this will help but it looks as though you need to reset your query_posts(); to give it another clean run
After each <?php endwhile;?> you would add
<?php wp_reset_query(); ?>
https://codex.wordpress.org/Function_Reference/wp_reset_query
Quote:
wp_reset_query() restores the $wp_query and global post data to the original main query. This function should be called after query_posts(), if you must use that function. As noted in the examples below, it's heavily encouraged to use the pre_get_posts filter to alter query parameters before the query is made.
Calling wp_reset_query is not necessary after using WP_Query or get_posts as these don't modify the main query object. Instead use wp_reset_postdata.

Check for Wordpress Thumbnail and display dummy if not there

got another question to ask:
I would like to display post thumbnails with the post title underneath. I have managed to work that out through asking on here, however now I would like to add a function that checks for a thumbnail and if none is available displays a dummy image.
Here is my try, which does display the thumbnail (if there) but not the dummy (if no thumbnail is attached):
<div class="gallery_container_wrapper">
<?php query_posts( $args ); if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
<div class="gallery_image_container">
<a href="<?php the_permalink(); ?>" title="<?php the_title_attribute(); ?>">
<div class="gallery_image_thumb">
<?php if ( has_post_thumbnail() ) {
the_post_thumbnail('thumbnail'); }
else {
echo
'<img src="http://www.kunstamkasten.de/wp-content/uploads/2014/08/gallery_dummy.jpg" />'
; } ?>
</div>
<div class="gallery_title">
<h2>
<?php the_title(); ?>
</h2>
</div>
</a>
</div>
<?php endwhile; else : ?>
<p><?php _e( 'Sorry, no posts matched your criteria.' ); ?></p>
<?php endif; ?>
<?php wp_reset_query(); ?>
</div>
What am I doing wrong here?
This code works for me. Yours is virtually identical.
<?php if ( has_post_thumbnail() ) : ?>
<?php the_post_thumbnail(); ?>
<?php else : ?>
<img src="<?php echo get_template_directory_uri(); ?>/images/sunlit_path_banner.jpg" alt="Sunlit Path" />
<?php endif; ?>
Note: I also cut and pasted your code and tested on my WP install, and it worked fine.
Or... try this alternative to the if condition:
<?php if ( get_the_post_thumbnail( get_the_ID() ) ) {
the_post_thumbnail('thumbnail'); }
else {
echo
'<img src="http://www.kunstamkasten.de/wp-content/uploads/2014/08/gallery_dummy.jpg" />'
; } ?>

Image resizing php code

I have this php code that displays the first image from a post on my main page. The images sizes seem to be random. I would like to make them all the same size.
You can see the three images at the bottom of the page:http://www.wha2wear.com/
And this is the code:
<div class="blog">
<h2><span>Sneak peak</span></h2>
<ul>
<?php query_posts('orderby=comment_count&posts_per_page=6'); if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
<li>
<h3 class="short_title"><a title="Post: <?php the_title(); ?>" href="<?php the_permalink(); ?>"><?php echo ShortTitle(get_the_title()); ?> </a></h3>
<?php getImage('1'); ?>
<?php endwhile; ?></li>
<?php else : ?>
<p>Sorry, no posts were found.</p>
<?php endif; ?>
</ul>
</div>
Thank you
Using HTML, you would need to use CSS to resize an image. You could use:
<img src="/page-to-image" style="width:100px; hight:200px" />
