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'] ); ?>"

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

I am trying to output an image using the bootstrap 4.0 class class in wordpress.
Here is the code I have in my loop:
<img class="card-img-top" src="<?php echo the_post_thumbnail('featured-large'); ?>" />
here is all of the code:
enter image description here
On output the images work correctly, but shows the ending "/>" on the page, after the image. As seen here:
Is there a reason this is happening, or is this code completely wrong?
You're echoing an img tag inside an img tag. Replace your <img/> tag with get_the_post_thumbnail(), and you can add your class to it like so:
echo get_the_post_thumbnail(get_the_ID(),'featured-large',array('class'=>'card-img-top');
the function you are using is display image, if you want to get the url just use this to fetch url of image and then put it into the img tag
$image = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), 'full' );
<img src="<?php echo $image[0];?>" class="img-responsive" alt="<?php the_title(); ?>">
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 $client_logo['url']; ?>
However, we don't know the architecture of your repeating field and without that knowledge we wouldn't be able to advise further. Update your post and I can update this answer if this info doesn't point you in the right direction.
I am trying to display an image caption for a wordpress Advanced Custom Fields (ACF) repeater field, and haven't had any luck with the follow three options:
<?php if($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 ( $carousel_logo ) { ?>
<img src="<?php the_field('carousel_logo'); ?>" />
<?php } else { ?>
<h2 class="promo">Default slider title </h2>
<?php }
?>
ACF's documentation on the Image field will provide more info on this.
I am using a wordpress theme that has a custom post type called "link" which simply produces a post where the title links to an outside link you specify. It also includes some text in the body of the post. I would like to also be able to display an image. Right now it is not showing the image.
Here is the code:
elseif ( has_post_format( 'link' )) {
if(get_post_meta($post->ID, '_format_link_url', true)!=''){
$link = get_post_meta($post->ID, '_format_link_url', true);
}else{
$link = '';
}
?>
<h2 class="entry-title">
<a href="<?php echo $link; ?>" target="_blank" title="Follow this link">
<?php the_title(); ?>
</a>
</h2>
<p>
Is there anything I can add to make it display an image as well as text?
Thanks!
I can't see anywhere on this example where you are using an tag to insert an image. The img tag has two required attributes, src and alt. Src is the path to your image, whereas alt is the alternate text for the image. So:
<img src="images/myImage.png" alt="This Is My Image"/>
Hope that helps!
