I have a wordpress project that is using ACF fields to pass images/video into a carousel. How would I get the alt text for the associated image?
I have tried to get_field('image') and various get_sub_field() calls, but image does not seem to be a field even though get_sub_field('still_image_url') and get_sub_field('image_link') are already pulling in the respective data for those fields.
I'm not even sure how to get the id for the image. Another php file is using the_ID();, but that is not working here.
<?php while (have_rows('top_slider')) : the_row(); ?>
<?php
$video_url = get_sub_field('video_url');
$video_url_responsive = get_sub_field('video_url_responsive');
$video_link = get_sub_field('video_link');
$image_url = get_sub_field('still_image_url');
$image_link = get_sub_field('image_link');
$has_target = strpos($image_link, '/') !== 0;
?>
Make sure you are using the return format of the Image either as IMAGE ARRAY or IMAGE ID.
Use the below code to get the ALT tag of the image if the return format is IMAGE ARRAY.
<?php
$image =get_sub_field('image');
if( !empty($image )): ?>
<img src="<?php echo esc_url($image['url']); ?>" alt="<?php echo esc_attr($image['alt']); ?>" />
<?php endif; ?>
Use the below code to get the ALT tag of the image if the return format is IMAGE ID.
$image_id = get_sub_field('image');
$img_url = wp_get_attachment_image_src($image_id, 'full');
$image_alt = get_post_meta($image_id, '_wp_attachment_image_alt', TRUE);
$image_title = get_the_title($image_id);
?>
<img src="<?php echo $img_url[0]; ?>" width="<?php echo $img_url[1]; ?>" height="<?php echo $img_url[2]; ?>" alt="<?php echo $image_alt; ?>" title="<?php echo $image_title; ?>">
Here the "image" denotes the field name which you set while creating the field.
get_sub_field('image');
Refer the image for understanding about Field Name, Return Format etc
You can see the image id and other details on the REST API if you will set the options to show on REST API.
After adding the contents to WP REST API, you can display the pages' content on the WP REST API as you can use this example link:
https://write-your-site-url-here/wp-json/wp/v2/pages
I've created custom post type as single-service.php and I have several custom taxonomies under service posts like education, recruit and health.
I currently created some queries and under each query, I want to create a button which direct the users the contact form page of that service. It is like when you get into a single service page which is categorized under education there will a button directs them to education contact form page likewise for recruit page.
I have tried below link but somehow it does not work. I am not sure whether I am using correct code or where do I make mistake
<?php if (in_category( 'education', $post->ID )) : ?>
<?php echo '<div class="button">Contact us</div>'; ?>
<?php elseif (in_category('recruit', $post->ID)) :?>
<?php echo '<div class="button">Contact us</div>'; ?>
<?php elseif (in_category('health', $post->ID)) :?>
<?php echo '<div class="button">Contact us</div>'; ?>
<?php endif;?>
I solve my problem by creating two custom fields in the template page and linking them with :
<div class="service-button">
<?php $info = get_post_meta(get_the_ID(), '_post_info', true); if (!$info) $info = array(); ?>
<a class="form" style="background-color:<?php echo $info['color'] ?>" href="<?php echo $info['form'] ?>">Contact us</a>
<?php if ($info['website']) : ?>
<a class="website" style="background-color:<?php echo $info['color'] ?>" href="http://<?php echo $info['website'] ?>"><?php echo $info['website'] ?></a>
<?php endif; ?>
</div>
I find this com_content/views/article/tmpl/default.php I created a template override and here is the code:
<?php if ($params->get('access-view')):?>
<?php if (isset($images->image_fulltext) && !empty($images->image_fulltext)) : ?>
<?php $imgfloat = (empty($images->float_fulltext)) ? $params->get('float_fulltext') : $images->float_fulltext; ?>
<div class="pull-<?php echo htmlspecialchars($imgfloat); ?> item-image">
<img
<?php if ($images->image_fulltext_caption):
echo 'class="caption"'.' title="' .htmlspecialchars($images->image_fulltext_caption) . '"';
endif; ?>
src="<?php echo htmlspecialchars($images->image_fulltext); ?>" alt="<?php echo htmlspecialchars($images->image_fulltext_alt); ?>"/> </div>
<?php endif; ?>
Before img tag how to form, modify this php code to be clickable the image to self url:
<a href="<?php echo JRoute::_(ContentHelperRoute::getArticleRoute($this->item->slug, $this->item->catid)); ?>"> <img
Here is the resolution:
<a href="<?php echo JURI::root().$images->image_fulltext; ?>">
Now the image is "clickalble" to self url
JURI::root() > your webpage url (like: something.com)
$images->image_fulltext > in joomla 3.1 you can choose an image what is displayed when you click to readmore, ie when you read the full article, that image have an url, like: /images/stories/freshsite/something.jpg
This php code combines these two code, to be: something.com/images/stories/freshsite/something.jpg > when you click on the image, only this image will shows in you browser :)
I am using the below code to display the main product image:
$productId = $this->getProduct_id();
$_product = Mage::getModel('catalog/product')->load($productId);
?>
<div class="single-image-large" onclick='window.open("<?php echo $_product->getProductUrl() ?>", "_self")'>
<img class="blog-image" src="<?php echo $this->helper('catalog/image')->init($_product, 'small_image')->resize(400, 400) ?>" width="400" height="400" alt="<?php echo $this->htmlEscape($_product->getName()) ?>" /><span class="img-caption"><?php echo $this->htmlEscape($_product->getName()) ?></span>
</div>
I would like to edit it so that it shows the product's second image. Any ideas how to achieve this?
I feel you can fetch the other images by using
$_product->getMediaGalleryImages()->getItemByColumnValue('label', 'LABEL_NAME')->getUrl();
or fetch the whole gallery and display it as per your requirement
Mage::getModel(’catalog/product’)->load($productId)->getMediaGalleryImages();
I want to make the joomla articles intro image to behave like the read more, and the title link. So the user clicks the image, and the article loads.
I'm not an PHP expert but maybe this is the readmore links code:
<a href="<?php echo $this->item->readmore_link; ?>" class="button<?php echo $this->item->params->get('pageclass_sfx'); ?>">
<?php if ($this->item->readmore_register) :
echo JText::_('Register to read more...');
elseif ($readmore = $this->item->params->get('readmore')) :
echo $readmore;
else :
echo JText::_("Read Article");
endif; ?></a>
This is what i want to do with every intro image on my joomla site.
Thanks !
Just resolved it!
your way of thinking helped me. Thank you!
here's my code:
<a href="<?php echo JRoute::_(ContentHelperRoute::getArticleRoute($this->item->slug, $this->item->catid)); ?>">
<?php
$images = json_decode($item->images);
if (isset($images->image_intro) and !empty($images->image_intro)) {
$imgfloat = (empty($images->float_intro)) ? $params->get('float_intro') : $images->float_intro;
$class = (htmlspecialchars($imgfloat) != 'none') ? ' class="size-auto align-'.htmlspecialchars($imgfloat).'"' : ' class="size-auto"';
$title = ($images->image_intro_caption) ? ' title="'.htmlspecialchars($images->image_intro_caption).'"' : '';
echo '<img'.$class.$title.' src="'.htmlspecialchars($images->image_intro).'" alt="'.htmlspecialchars($images->image_intro_alt).'" />';
}
echo $this->item->introtext;
?>
</a>
for Joomla 2.5:
in your override for _item.php (Location: yourtemplate\html\mod_articles_news\item.php)
place the following line:
<?php if ($params->get('image')) : ?>
<?php $images = json_decode($item->images); ?>
<?php if (isset($images->image_intro) and !empty($images->image_intro)) : ?>
<img src="<?php echo htmlspecialchars($images->image_intro); ?>" alt="<?php echo htmlspecialchars($images->image_intro_alt); ?>"/>
<?php endif; ?>
<?php endif; ?>
Place it there where you would like it to show up
For example after:
<?php echo $item->beforeDisplayContent; ?>
Your intro image has become a link now.
the isset part, makes sure that if a viewer uses Internet Explorer, it doesn't show up a small red cross box.
Just for the information:
in blog_item.php you can find an example code how it's shown up in an article. Here you can also find the code for imagefloat etc.
<?php if (isset($images->image_intro) and !empty($images->image_intro)) : ?>
<?php $imgfloat = (empty($images->float_intro)) ? $params->get('float_intro') : $images->float_intro; ?>
<div class="img-intro-<?php echo htmlspecialchars($imgfloat); ?>">
<img
<?php if ($images->image_intro_caption):
echo 'class="caption"'.' title="' .htmlspecialchars($images->image_intro_caption) .'"';
endif; ?>
src="<?php echo htmlspecialchars($images->image_intro); ?>" alt="<?php echo htmlspecialchars($images->image_intro_alt); ?>"/>
</div>
<?php endif; ?>
So let me start by explaining what the code that you've posted above does. The entire block of code generates one link: there are a bunch of if statements that are determined based off some settings. For example, if you have set that people need to register in order to read more, the link will say "Register to read more..."
The part that we're interested in here, however, since we want to turn images into links, is the URL that we want the images to link to. This is right in the first line:
<a href="<?php echo $this->item->readmore_link; ?>"
so we know that the URL is provided dynamically thanks to $item->item->readmore_link and all this code is doing is echoing it into the HTML.
All that's left is to edit your Joomla template of the page on which you have your images (probably the same file you took this code from). It looks like this should be part of a greater PHP loop, which loops through all the posts. Somewhere above where you found this code, should be code for the intro image that goes along with that post.
I'm not sure what it'll look like, it could be a <img src="<? stuff here; ?> /> or it could be dynamically generated. Keep reading. If you're still not sure where to find it at the end, edit your post with the full code of the template where you got the above snipping from. Regardless of what it looks like, it is referred to as <WHATEVER IMAGE CODE YOU FOUND ABOVE> in the following step:
You have to wrap that image with "a" tags so that it looks like the following:
<WHATEVER IMAGE CODE YOU FOUND ABOVE>
That should do it. Let me know if you have any trouble, I'll be more than happy to make my post more specific if you can provide more detailed information, but I've tried to explain it well enough that you should be able to figure it out with a couple tries.
As you stated you are not a PHP expert, it sounds like your best bet will be to use a Joomla extension that has similar functionality to what you want.
I believe mod_minifrontpage will work for what you need. It allows you to display a list of articles, and it generates thumbnails for those articles based on the first image to be referenced.
There are article intro images in J, since 1.7.5 and now in latest 2.5.3
what you need is change the defaults for component_content,
you can do it 2 ways, editing views in yourinstall/components/com_content/views/
or use template overrides , you first need to know if your template IS using overrides otherwise if you edit component views in the component itself you will not see changes.
to verify this , go to
site_name/templates/template_name/html folder and check if there is folder name
com_content ,
if that is the case than your template is using overrides and any edits should be done trough there not through component
now to the actual code
this is in
components\com_content\views\featured\tmpl\default_item.php ( THIS I DEFAULT FRONTPAGE ARTICLE VIEW)
<?php if (isset($images->image_intro) and !empty($images->image_intro)) : ?>
<?php $imgfloat = (empty($images->float_intro)) ? $params->get('float_intro') : $images->float_intro; ?>
<div class="img-intro-<?php echo htmlspecialchars($imgfloat); ?>">
<img
<?php if ($images->image_intro_caption):
echo 'class="caption"'.' title="' .htmlspecialchars($images->image_intro_caption) .'"';
endif; ?>
src="<?php echo htmlspecialchars($images->image_intro); ?>" alt="<?php echo htmlspecialchars($images->image_intro_alt); ?>"/>
</div>
<?php endif; ?>
all you would need to do is wrap a element around IMG tag with readmore link like this
<a href="<?php echo $this->item->readmore_link; ?>">
<img
<?php if ($images->image_intro_caption):
echo 'class="caption"'.' title="' .htmlspecialchars($images->image_intro_caption) .'"';
endif; ?>
src="<?php echo htmlspecialchars($images->image_intro); ?>" alt="<?php echo htmlspecialchars($images->image_intro_alt); ?>"/>
</a>
DO NOT forget that if there is template override for com_content you wold need to edit the featured/default_item.php inside it
In Joomla 3.1, the intro_image layout has been moved to the layouts/joomla/content folder. In my situation, it is called from com_content/views/category/tmpl/blog_item.php like so:
<?php echo JLayoutHelper::render('joomla.content.intro_image', $this->item); ?>
I moved that file to my template/html/com_content/category/blog_item.php and then wrapped the call to JLayoutHelper like so:
<?php $link = JRoute::_(ContentHelperRoute::getArticleRoute($this->item->slug, $this->item->catid)); ?>
<a href="<?php echo $link; ?>">
<?php echo JLayoutHelper::render('joomla.content.intro_image', $this->item); ?>
</a>
If you have Gantry installed on Joomla 3.1, the overrides are in a different location. You will want to navigate to plugins/system/gantry/overrides/3.0/2.5/com_content/category/blog_item.php and wrap the intro image with the read more link code.
<?php $link = JRoute::_(ContentHelperRoute::getArticleRoute($this->item->slug, $this->item->catid)); ?>
<a href="<?php echo $link; ?>"><img
<?php if ($images->image_intro_caption):
echo 'class="caption"'.' title="' .htmlspecialchars($images->image_intro_caption) .'"';
endif; ?>
src="<?php echo htmlspecialchars($images->image_intro); ?>" alt="<?php echo htmlspecialchars($images->image_intro_alt); ?>"/></a>
