I'm using Owl Carousel to create a carousel gallery of logos. I'm using Advanced Custom Field's repeater feature to grab all of the urls of the logos. Here's the markup for the gallery:
<div id="clients">
<?php
$clients = get_field('client_carousel');
$client_logo = get_field('client_logo');
if( $clients ) {
?>
<section>
<div id="owl-clients" class="owl-theme owl-carousel">
<?php foreach( $clients as $client_logo ): ?>
<div class="item">
<img class="featurette-image img-responsive center-block" src="<?php echo $client_logo['url']; ?>" alt="<?php echo $client_logo['alt']; ?>"></div>
<?php endforeach; ?>
</div>
</section>
<?php } ?>
</div><!--end clients-->
The repeater field name is client_carousel and the field name of the field within it is client_logo.
I have a working demo here. It recognizes the seven logos in the group, but the only thing I can't get is the url for the img src.
Couple things to note. You're overriding the $client_logo variable, so not sure if that was just an abandoned artifact in the code since it doesn't look like you use it anyhow:
$client_logo = get_field('client_logo');
<?php foreach( $clients as $client_logo ): ?>
Other thing is ACF repeater field allows you to choose the output of the field type "image" - assuming that's what you set for the "url" field. Now, suppose you set "url" as an image, you can then select the output as Image URL instead of the default Image Array if you want the raw URL returned.
Supposing that's how you set it, then it should give you the image url without having ot modify your code:
<?php echo $client_logo['url']; ?>
However, we don't know the architecture of your repeating field and without that knowledge we wouldn't be able to advise further. Update your post and I can update this answer if this info doesn't point you in the right direction.

I am looking to add Alt text to slider images. I was able to add the line:
alt ="<?= $alt = get_post_meta(get_post_thumbnail_id($post->ID), '_wp_attachment_image_alt', true); ?>"
This line pulled in the alt text for the photos but it is the same alt text for all the photos within the slider. It doesn't seem to loop each alt text to each photo. Below is the code that pulls the images.
<?php $_gallery = get_field('project_gallery_photos'); ?>
<?php if( $_gallery ) { ?>
<div class="_featured-images">
<div class="_slider">
<?php foreach( $_gallery as $_img ): ?>
<div class="_slide">
<img src="<?= $_img['photo']['sizes']['project-images']?>" alt ="<?= $alt = get_post_meta(get_post_thumbnail_id($post->ID), '_wp_attachment_image_alt', true); ?>"/>
<?php if( $_img['photo_title'] || $_img['photo_caption'] ) { ?>
<div class="_caption">
<?= $_img['photo_title']? '<b>'.$_img['photo_title'].'</b><br>': '' ?>
<?= $_img['photo_caption'] ?>
</div>
<?php } ?>
</div>
<?php endforeach; ?>
</div>
What you're pulling in as the meta description for the "featured image" of the current global $post, which the gallery photos appear to be Advanced Custom Field for.
What you should be pulling in instead would be one of those settings from the foreach() loop. If you're using the standard ACF Pro Gallery field, the alt attribute is included at the first level of the array.
alt="<?= esc_attr( $_img['alt'] ); ?>"
Otherwise, you should be able to use print_r( $_img ); to find the attribute you need, for instance if your $_img contains a 'photo' key, you may need to use:
alt="<?= esc_attr( $_img['photo']['alt'] ); ?>"

Linked Description
foreach()
The foreach construct provides an easy way to iterate over arrays. foreach works only on arrays and objects, and will issue an error when you try to use it on a variable with a different data type or an uninitialized variable. There are two syntaxes:
print_r()
Prints human-readable information about a variable
esc_attr()
Escaping for HTML attributes
ACF Gallery
The Gallery field provides an interactive interface for managing a collection of attachments.
I have a wordpress with acfpro. I use it the options page for to create option page header and footer, next I declare custom field map on option page footer and paste code in footer.php.
when I do it this, i have some pages where acf map not working and other pages is good!
wordpress 5.2, acfpro 5.7.13
<div class="left">
<div class="zto-containMap">
<?php
$location = get_field('map');
$long = $location['lng'];
$lat = $location['lat'];
if( !empty($location) ):
?>
<div class="acf-map">
<div class="marker" data-lat="<?php echo $lat; ?>" data-lng="<?php echo $long; ?>"></div>
</div>
<?php else: ?>
<div class="acf-map">
not working
</div>
<?php endif; ?>
</div>
</div>
I don't have a error message, and acf map is broken on 3 page on my site and the other pages are working nice width acf map
If you want to get the field value for an option, you have to declare the option scope in your second paramter of get_field($field, $scope). If no $scope is passed in the get_field() function it will automatically use the ID value of get_post().
This is what you're after:
$location = get_field('map', 'option');
Here's the docs on getting the value of an Option field in ACF.
While this is a little out of the scope of your question, these docs explain a little further about how the $scope variable can be used in the second parameter.
I would like that my php detects seperatly images (media) and text, from a same wordpress post, in regard to display them in different columns. I am using Bootstrap, and I would like different display of each (text and image) according to the screen size.
Here is a code I have that displays all of the content of my post (image and text) at once, it works perfectly :
<div class="container">
<?php if (have_posts()): ?>
<div class="container">
<?php while(have_posts()): the_post(); ?>
<div class="row">
<div class="col-xs-12 col-md-12 col-lg-12">
<?php the_content(); ?>
</div>
</div>
<?php endwhile; ?>
</div>
<?php endif; ?>
</div>
I would like the same way of loading content but instead of having just
<?php the_content(); ?>
I would like something like this to place text and image (of same post) in different div class:
<?php the_image(); ?>
AND
<?php the_text(); ?>
I know this is wrong code but I am trying to be clear in my explanation. I need that my client does not touch any of code, also shortcode in Wordpress post. Any input or advice would be very appreciated!
Many thanks!
Thank you for your answer! Lars Beck, you solved my problem!
Here is the code I was looking for:
<?php
//get content from back office , filter imgs except featured img to place them later in <div id='img_content_right'>
$content2 = get_the_content();
$removed_imgs = array();
$content2 = preg_replace_callback('#(?!<img.+?id="featured_img".*?\/>)(<img.+? />)#',function($r) {
global $removed_imgs;
$removed_imgs[] = $r[1];
return '';
},$content2);
//add filter to the_content to strip images except img_menu et featured_img
add_filter('the_content', 'strip_images',2);
function strip_images($content){
$content=preg_replace('/(?!<img.+?id="img_menu".*?\/>)(?!<img.+?id="featured_img".*?\/>)<img.+?\/>/','',$content);
return $content;
}
the_content();
?>
<div id='img_content_right'>
<?php
//append the images stripped from content
foreach($removed_imgs as $img){
echo $img;
}
?>
</div>
There is no way, to separate out images from the content section if they have just been included as part of the content.
Wordpress has featured image functionality built in for you. so you can use the_post_thumbnail() to echo out the image. Maybe this question can help you Wordpress featured image code
If this isn't enough for you and you need more flexibility you might want to look at advanced custom fields plugin - https://www.advancedcustomfields.com/ it makes it easy for you to add your own fields of any type you want.
I am trying to display an image caption for a wordpress Advanced Custom Fields (ACF) repeater field, and haven't had any luck with the follow three options:
<?php if($middle_image['image']): ?>
<?php $midimage = wp_get_attachment_image_src($middle_image['image']); ?>
<?php $caption = $midimage->post_excerpt; ?>
<?php $captiontwo = $middle_image['image']['caption'] ?>
<?php $captionthree = $middle_image['image']->post_excerpt; ?>
<?php $alt = get_post_meta($middle_image['image'], '_wp_attachment_image_alt', true); ?>
<?php $main_image = wp_get_attachment_image_src($middle_image['image'], 'two-column-cropped' ); ?>
<div class="two-column-cropped"><img src="<?php echo $main_image[0]; ?>" alt="<?php echo $alt ?>" />
<?php if($caption) { ?>
<div class="image_caption"><?php echo $caption; ?></div>
<?php } ?>
</div>
<?php endif; ?>
Any suggestions would be appreciated. Thanks.
wp_get_attachment_src() does not fetch any data about an image besides the URL, height and width. You might want wp_get_attachment_metadata() however I think you would be better off changing your ACF field to return an Image Object (actually an array) instead of the Image ID (as I assume you have it now).
ACF can return any of three things for an image field: The image src URL, the Attachment ID (which can be passed to functions such as wp_get_attachment_image_src()), or the attachment information as an array.
You can check that you are receiving the correct response from ACF by using var_dump($middle_image) or var_dump($midimage)
I assume that $middle_image is your repeater field.
As long as ACF is configured correctly to return the image object (instead of the image URL or ID), you can simply remove this line:
<?php $midimage = wp_get_attachment_image_src($middle_image['image']); ?>
and then access the image caption using $middle_image['image']['caption']
I'm trying to give a client some options in the WP backend to customize a carousel that is displayed on their website's homepage. I am using Advanced Custom Fields to handle getting the input from the client. I want to give them two options:
Option #1) Allows the client to insert a string of text to be displayed ('carousel_title_text')
Option #2) Allows the client to upload a logo to be displayed ('carousel_logo')
I want the code to check for title text, and if there is none, display the logo instead. I haven't yet decided what will happen if both fields are empty. Anyway, here is what I've come up with:
<?
if( get_field('carousel_title_text') ) { ?>
<h2 class="promo"><?php the_field('carousel_title_text');?></h2>
<? } elseif( get_field('carousel_logo') ) {
the_field('carousel_logo');
}
?>
The 'carousel_title_text' displays as long as there is an input, but when it's empty and 'carousel_logo' is not, it does not properly output the logo. Can anyone tell me what I'm doing wrong or if there's a better approach?
Thanks in advance,
If I get it right, your problem is not with the If/Else statement but with the logo field. I assume you properly configured this field (carousel_logo) as Image in ACF.
Image fields offer three different Return Value possibilities:
Note: In some versions of ACF you'll found Image Object instead of Image Array, but it's conceptually the same.
None of them will show your image properly if you just use the_field('carousel_logo'); in your template. So, how do you get your logo?
If you want the easiest solution, choose Image URL as Return Value for your logo field and print it like that:
<?
$title = get_field('carousel_title_text');
$logo = get_field('carousel_logo');
if (!empty($title)) : ?>
<h2 class="promo"><?= $title ?></h2>
<?php elseif (!empty($logo)) : ?>
<img class="logo" src="<?= $logo ?>">
<?php else: ?>
<!-- No title, no logo -->
<?php endif ?>
I've changed a little your code, but basically the key line here is:
<img class="logo" src="<?= $logo ?>">
This, or the equivalent:
<img class="logo" src="<?php echo $logo ?>">
should show your image when the title is missing.
Bonus: If you're handling different thumbnail sizes I'd recommend you to use Image Array as Return Value. In that case, $logo would be an Array containing all information (such as sizes, all thumbnail URLs, captions, etc.)
Use:
<img class="logo" src="<?= $logo['sizes']['medium'] ?>">
where 'medium' is your thumbnail size label to output it.
Also, please check official docs on ACF's Image field type for more examples and further explanations.
You have put else condition on last, that will default text will show if client will not Enter text ot logo.
you will used bellow code.
<?php
if( get_field('carousel_title_text') ) { ?>
<h2 class="promo"><?php the_field('carousel_title_text');?></h2>
<?php } elseif( get_field('carousel_logo') ) {
the_field('carousel_logo');
}else {
echo " <h2 class="promo"> Default slider title </h2>"
}?>
it's default title client indicate to he has not entered slider text
Hope it's work for you.
Try:
<?php
$output = (get_field('carousel_title_text')) ? get_field('carousel_title_text'):get_field('carousel_logo');
echo $output;
?>
This sounds like it's to do with the settings for the logo, which I'm assuming is an image field? In the Wordpress admin there will be a setting under that field called 'Return value' which can be set to either 'Array' or 'URL'.
If this is set to 'Array', you'd need to store that array to a variable and then access its properties in your markup like so:
<?php
if ( get_field('carousel_title_text') ) { ?>
<h2 class="promo"><?php the_field('carousel_title_text'); ?></h2>
<?php } else{
$carousel_logo = get_field('carousel_logo');
if ( $carousel_logo ) { ?>
<img src="<?php echo $carousel_logo['url']; ?>" />
<?php } else { ?>
<h2 class="promo">Default slider title </h2>
<?php }
}
?>
Alternatively, you could set your field to only return the image URL and then access it like so:
<?php
if ( get_field('carousel_title_text' ) { ?>
<h2 class="promo"><?php the_field('carousel_title_text'); ?></h2>
<?php } elseif ( $carousel_logo ) { ?>
<img src="<?php the_field('carousel_logo'); ?>" />
<?php } else { ?>
<h2 class="promo">Default slider title </h2>
<?php }
?>
ACF's documentation on the Image field will provide more info on this.
