I have three separate fields in acf one for each image named slide_one, slide_two and slide_three. Now when I try to get the images to display using the code below nothing is being output. I am doing it this why and not using a loop like you usually as I'm wanting to have a separate text overlay for each image that I will have sliding in separately. This is the first step and it won't work. What an I doing wrong?
<div class="slider">
<ul class="slides">
<?php
$image_one = get_field('slide_one');
if( !empty($image_one ): ?>
<li>
<img src="<?php echo $image_one['url']; ?>" alt="<?php echo $image_one['alt']; ?>" />
</li>
<?php endif; ?>
<?php
$image_two = get_field('slide_two');
if( !empty($image_two ): ?>
<li>
<img src="<?php echo $image_two['url']; ?>" alt="<?php echo $image_two['alt']; ?>" />
</li>
<?php endif; ?>
<?php
$image_three = get_field('slide_three');
if( !empty($image_three ): ?>
<li>
<img src="<?php echo $image_three['url']; ?>" alt="<?php echo $image_three['alt']; ?>" />
</li>
<?php endif; ?>
</ul>
</div>

I have some code here that outputs the following:
Essentially I want to use same page anchor tags so a user can click on the small logo and be taken to the larger logo and info.
As it's a Wordpress site, I have used the ACF repeater field to achieve this. This repeater field enables the user in the back end to add more clients, for each client they can add an image a company name and the paragraph text.
Then I have just repeated the repeater field above and shown only the images but made them much smaller.
As you will see in the code below, I have assigned around each smaller photo and then this: <a name="anchor1"></a> just above every larger photo..
But I need a way of the numbers counting up so when they come out they aren't all anchor1 they become anchor2, anchor3 and so on.
Any ideas?
<div class="container client-page-logos-small" >
<div class="row">
<h3>Click company to see more</h3>
<?php if( have_rows('client_page_logos', 123456) ): ?>
<ul class="client-page-logos-small">
<?php while( have_rows('client_page_logos', 123456) ): the_row();
// vars
$logo = get_sub_field('client_page_logo');
?>
<a href="#anchor1">
<li class="client-page-logos-small">
<img src="<?php echo $logo['url']; ?>" alt="<?php echo $logo['alt'] ?>" />
</li>
</a>
<?php endwhile; ?>
</ul>
<div style="clear: both;"></div>
<?php endif; ?>
<hr>
</div>
</div>
<div class="container client-page-logos" >
<div class="row">
<?php if( have_rows('client_page_logos', 123456) ): ?>
<ul class="client-page-logos">
<?php while( have_rows('client_page_logos', 123456) ): the_row();
// vars
$logo = get_sub_field('client_page_logo');
$name = get_sub_field('client_name');
$text = get_sub_field('client_text');
?>
<li class="client-page-logos">
<a name="anchor1"></a>
<img src="<?php echo $logo['url']; ?>" alt="<?php echo $logo['alt'] ?>" />
<h3><?php echo $name; ?></h3>
<p><?php echo $text; ?></p>
</li>
<?php endwhile; ?>
</ul>
<?php endif; ?>
</div>
</div>
You need to add counter like below:-
<?php
$i = 1;
while( have_rows('client_page_logos', 123456) ): the_row();
// vars
$logo = get_sub_field('client_page_logo');
?>
<a href="#anchor<?php echo $i;?>">
<li class="client-page-logos-small">
<img src="<?php echo $logo['url']; ?>" alt="<?php echo $logo['alt'] ?>" />
</li>
</a>
<?php $i++;endwhile; ?>
And
<?php
$j = 1;
while( have_rows('client_page_logos', 123456) ): the_row();
// vars
$logo = get_sub_field('client_page_logo');
$name = get_sub_field('client_name');
$text = get_sub_field('client_text');
?>
<li class="client-page-logos">
<a name="anchor<?php echo $j;?>"></a>
<img src="<?php echo $logo['url']; ?>" alt="<?php echo $logo['alt'] ?>" />
<h3><?php echo $name; ?></h3>
<p><?php echo $text; ?></p>
</li>
<?php $j++ ;endwhile; ?>
The code to generate a list of most read articles on my Joomla website AND display their intro images is as follows:
<ul class="mostread<?php echo $moduleclass_sfx; ?>">
<?php foreach ($list as $item) : ?>
<?php $images = json_decode($item->images); ?>
<?php if( $images->image_intro ) : ?>
<img src="<?php echo $images->image_intro; ?>" alt="<?php echo htmlspecialchars($item->title); ?>" />
<?php endif; ?>
<li itemscope itemtype="https://schema.org/Article">
<a href="<?php echo $item->link; ?>" itemprop="url">
<span itemprop="name">
<?php echo $item->title; ?>
</span>
</a>
</li>
<?php endforeach; ?>
</ul>
Having little to no experience with PHP, what do i need to do to this code to make it display only the first item's image instead of for all of them?
#hek-mat was close, but the OP was trying to stop the image on the other posts from displaying, not the link and title.
<?php
// track if we've seen an image yet or not
$seen_first = false;
foreach ( $list as $item ) :
$images = json_decode( $item->images );
// OP only wants posts with image_intros
if ( $images->image_intro ) :
// OP only wants to see the first item's image
if ( ! $seen_first ) :
?>
<img src="<?php echo $images->image_intro; ?>" alt="<?php echo htmlspecialchars( $item->title ); ?>" />
<?php
// don't show another image
$seen_first = true;
// end "if first not seen yet"
endif;
// show the article (for all)
?>
<li itemscope itemtype="https://schema.org/Article">
<a href="<?php echo $item->link; ?>" itemprop="url">
<span itemprop="name"><?php echo $item->title; ?></span>
</a>
</li>
<?php
// end "if image_intro"
endif;
endforeach;
?>
Try like this..
Set a variable $first = true; after displaying first item set it to false.
<ul class="mostread<?php echo $moduleclass_sfx; ?>">
<?php
$first = true;//initially set true
foreach ($list as $item) : ?>
<?php $images = json_decode($item->images); ?>
if($first==true){ ?> //checks $first is true if true prints
<?php if( $images->image_intro ) : ?>
<img src="<?php echo $images->image_intro; ?>" alt="<?php echo htmlspecialchars($item->title); ?>" />
<?php endif;
<li itemscope itemtype="https://schema.org/Article">
<a href="<?php echo $item->link; ?>" itemprop="url">
<span itemprop="name">
<?php echo $item->title; ?>
</span>
</a>
</li>
<?php
}
$first = false;//after printing first item set it false
endforeach; ?>
</ul>
To display only first item image you have do it like below.
<?php
$first = true;//initially set true
foreach ($list as $item) :
$images = json_decode($item->images);
if($first==true):
if( $images->image_intro ) : ?>
<img src="<?php echo $images->image_intro; ?>" alt="<?php echo htmlspecialchars($item->title); ?>" />
<?php
endif;
endif;
$first = false;
?>
<li itemscope itemtype="https://schema.org/Article">
<a href="<?php echo $item->link; ?>" itemprop="url">
<span itemprop="name">
<?php echo $item->title; ?>
</span>
</a>
</li>
<?php endforeach; ?>
Rather than modifying the PHP, it is probably easier to add some CSS to a custom CSS file like this:
ul.mostread img {display: none;}
ul.mostread img:first-of-type {display: block;}
so that only the first image is displayed.
See https://joomla.stackexchange.com/a/3878/120 for instructions on how to create a custom CSS file in Joomla.
A custom CSS file also has the advantage that it won't be overwitten by any future Joomla or template updates.
I am struggling to retrieve the intro image of articles, within a custom module that echoes article titles with the selected tags.
But it seems as if $item->images doesn't recall the image info. My code is the following:
Can anyone help me?
<?php
defined('_JEXEC') or die;
$images = json_decode($item->images);
?>
<?php JLoader::register('TagsHelperRoute', JPATH_BASE . '/components/com_tags/helpers/route.php'); ?>
<div class="tagsselected<?php echo $moduleclass_sfx; ?>">
<?php if ($list) : ?>
<ul>
<?php foreach ($list as $i => $item) : ?>
<li>
<?php $item->route = new JHelperRoute; ?>
<a href="<?php echo JRoute::_(TagsHelperRoute::getItemRoute($item->content_item_id, $item->core_alias, $item->core_catid, $item->core_language, $item->type_alias, $item->router)); ?>">
<?php if (!empty($item->core_title)) :
echo htmlspecialchars($item->core_title);
endif; ?>
</a>
<img src="<?php echo $images->image_intro; ?>" alt="<?php echo htmlspecialchars($item->title); ?>" />
</li>
<?php endforeach; ?>
</ul>
<?php else : ?>
<span><?php echo JText::_('MOD_TAGS_SIMILAR_NO_MATCHING_TAGS'); ?></span>
<?php endif; ?>
</div>
Try to get Article images in for loop
<?php foreach ($list as $i => $item) :
// images for each article
$images = json_decode($item->images); ?>
<li>
// your code/ other stuff

<img src="<?php echo $images->image_intro; ?>" alt="<?php echo htmlspecialchars($item->title); ?>" />

I am trying to build a Flexible Content which contains 4 possible Layouts (a description, a hero image, a gallery 1col and a gallery 2col). So far I can get the Description and Hero Image subfields to display just fine but the Gallery subfield wont show up on the page. Don't know what I'm doing wrong. Here's the code:
<?php
while(the_flexible_field("flexible_content")): ?>
<?php if(get_row_layout() == "description"): // layout: Description ?>
<div class="proy-desc">
<h2><?php the_sub_field("text"); ?></h2>
</div>
<?php elseif(get_row_layout() == "hero_image"): // layout: Hero Image ?>
<div class="proy-img">
<?php
$image = get_sub_field('image');
elseif( !empty($image) ): ?>
<img src="<?php echo $image['url']; ?>" alt="<?php echo $image['alt']; ?>" />
<?php ?>
</div>
<?php elseif(get_row_layout() == "gallery_50p"): // layout: Gallery 50p ?>
<div class="gallery">
<?php $images = get_sub_field('gallery_image_50p');
if( $images ): ?>
<ul>
<?php foreach( $images as $image ): ?>
<li>
<img src="<?php echo $image['url']; ?>" alt="<?php echo $image['alt']; ?>" />
</li>
<?php endforeach; ?>
</ul>
<?php ?>
</div>
<?php endif; ?>
<?php elseif(get_row_layout() == "gallery_100p"): // layout: Gallery 50p ?>
<div class="gallery">
<?php $images = get_sub_field('gallery_image_100p');
if( $images ): ?>
<ul>
<?php foreach( $images as $image ): ?>
<li>
<img src="<?php echo $image['url']; ?>" alt="<?php echo $image['alt']; ?>" />
</li>
<?php endforeach; ?>
</ul>
<?php ?>
</div>
<?php endif; ?>
<?php endif; ?>
<?php endwhile; ?>
You did not close your if statement. See below:
<?php elseif(get_row_layout() == "gallery_50p"): // layout: Gallery 50p ?>
<div class="gallery">
<?php $images = get_sub_field('gallery_image_50p');
if( $images ): ?>
<ul>
<?php foreach( $images as $image ): ?>
<li>
<img src="<?php echo $image['url']; ?>" alt="<?php echo $image['alt']; ?>" />
</li>
<?php endforeach; ?>
</ul>
<?php ?>
</div>
<?php endif; ?>
Change your section to this:
<?php elseif(get_row_layout() == "gallery_50p"): // layout: Gallery 50p ?>
<div class="gallery">
<?php $images = get_sub_field('gallery_image_50p');
if( $images ): ?>
<ul>
<?php foreach( $images as $image ): ?>
<li>
<img src="<?php echo $image['url']; ?>" alt="<?php echo $image['alt']; ?>" />
</li>
<?php endforeach; ?>
</ul>
<?php endif; ?>
</div>
Your endif; was in the wrong spot. Everything else looks right, so give this a try.
Hi I've been working with Kirby. I'm a complete beginner in PHP but managed to get a lot done. Just need some help with the gallery.
On the homepage a single image is displayed as thumbnail:
<?php foreach($articles as $article): ?>
<li class="<?php foreach(str::split($article->tags()) as $tag): ?><?php echo $tag ?> <?php endforeach ?>">
<?php foreach($article->images() as $image): ?><?php echo thumb($image, array('width' => 300, 'quality' => 70)) ?><?php endforeach ?><p><?php echo html($article->title()) ?></p>
</li>
<?php endforeach ?>
On the article page I'd like to have a gallery.
The gallery snippet:
<?php if($page->hasImages()): ?>
<ul class="gallery">
<?php foreach($page->images() as $image): ?>
<li>
<img src="<?php echo $image->url() ?>" width="<?php echo $image->width() ?>" height="<?php echo $image->height() ?>" alt="<?php echo $image->name() ?>" />
</li>
<?php endforeach ?>
</ul>
<?php endif ?>
Using Kirby, makes me store all the article items in one folder. But if I do this, and use the code mentioned above, all the images from the gallery also show up as thumbnails on the homepage.
I guess the best would be to edit the gallery snippet so it can grab images from a subfolder. But how?
Thank you for your help!
One solution to this is to name the file you wanna have displayed on the front page something like front.jpg. You can then directly access this image with $page->images()->find('front.jpg').
So you get this:
<?php foreach($articles as $article): ?>
<li class="<?php foreach(str::split($article->tags()) as $tag): ?><?php echo $tag ?> <?php endforeach ?>">
<a href="<?php echo $article->url() ?>" title="<?php echo html($article->title()) ?>">
<?php echo thumb($article->images()->find('front.jpg'), array('width' => 300, 'quality' => 70)) ?>
<p><?php echo html($article->title()) ?></p>
</a>
</li>
<?php endforeach ?>
(Note, that you have to remove the inner foreach-loop, because you're only displaying one image.)
The gallery snippet stays the same.
Here try:
<?php foreach($page->image()->yaml() as $image): ?>
<?php if($img = $page->image($image)): ?>
<img src="<?= $img->url() ?>" alt="<?= $page->title()->html() ?>" width="100%" height="100%" />
<?php endif ?>
<?php endforeach ?>
