I need to add a custom field to my article post but not sure how to add an additional class to it.
Currently the classes get pulled through like this <?php post_class($classes); ?>.
However I need to add a custom field to this as well. To demonstrate ive added a class= but this doesnt work as class= is being added twice.
<?php post_class($classes); ?> class="<?php the_field( "size" ); ?>
So i need post_class and the_field to work together.
Thanks for your answers but I've found a simple way to do this
<?php post_class(get_field('field_name')); ?>
You can do this with two different way,
First:- Add following code in theme's functions.php file:
This will add your class where post_class is called.
function category_id_class($classes)
{
global $post;
if($post->post_type == 'post')
{
$classes[] = get_field( "size" );;
}
return $classes;
}
add_filter('post_class', 'category_id_class');
Second:- Add this following code directly into your page:-
$post_classes = get_post_class();
$post_classes= implode(' ', $post_classes);
echo 'class="'.$post_classes. the_field( "size" )'"';
Hope this will help you little bit.
So why you could not do like this:
<?php post_class(the_field( "size" )); ?>
Because it is working like this:
<?php post_class('my_custom_class'); ?>

I am trying to get a different icon to appear next to an event in Wordpress. I am use the "The Event Calendar" plugin and the events are stored as taxonomies. I have three taxonomies. "Tax1", "Tax2" and "Tax3".
I cannot seem to figure out how to call to check what the taxonomies are and assign an icon to each one. Here is what I have so far.
" title="" rel="bookmark">
<?php $taxonomy_exist = taxonomy_exists( 'Tax2' ); ?>
<?php if(is_tax($taxonomy_exist)) { ?>
<p>working!!!!!!!!!!</p>
<?php } else { ?>
<img class="cat-icon" src="/wp-content/uploads/2017/11/Heart.png" />
<?php } ?>
<?php $title = get_the_title($event); ?>
<?php if (strlen($title) > 30) { ?>
<?php echo mb_strimwidth($title, 0, 30, '...'); ?>
<?php } else { ?>
<?php echo $title ?>
<?php }?></a></span><!--.event-title-->
So it is getting to the if statement and failing, showing the heart icon. How can I see if it is part of the "Tax2" taxonomy?
Problem 1:
is_tax() accepts taxonomy names as a first argument. But you put $taxonomy_exist parameter which is boolean. (true/false). Of course it should not work and always return zero. Because there is not any taxonomy called "true" or "false".
Problem 2: Are you sure that tax1, tax2 and tax3 are taxnomies? may be they are terms? if they are terms then i will add a solution code as an update to this answer. If they are taxonomies, then i don't see any logic there. Because taxonomies are not objects to be related to posts. Taxonomy is name of categorization, terms are member elements of those taxonomies.
I'm customizing a Wordpress Theme and i have stucked in add a custom class to the "the_excerpt()".
I have searched on the web for this function, but nothing is specific to add a custom class.
Hm, i've tried the "get_the_excerpt", but this one doesn't work (returns nothing).
Anyone knows how to do this?
<?php echo get_the_excerpt(); ?>
Shows the excerpt
<p class="your-class"><?php echo get_the_excerpt(); ?></p>
Shows the excerpt in a div with a class
As far as I'm concern wordpress doesnt provide a solution for this however you can try printing the excerpt using this solutions:
Solution 1: printing the class in the page.
<?php echo '<p class="yourclass">' . get_the_excerpt() . '</p>' ?>;
Link of where i found answer 1
Solution 2: override excert function:
You can override the excerpt function in wordpress functions.php using the following code and pasting in the same file:
function my_custom_excerpt( $excerpt ) {
$post_excerpt = '<p class="yourclass">' . $post_excerpt . '</p>';
return $post_excerpt;
}
add_filter( 'the_excerpt', 'my_custom_excerpt', 10, 1 );
Link where i found answer 2
Conclusion: I prefer using the solution #1 because is cleaner and very understable for someone which will maintain the site.
You can add this code to your functions.php to add the class myclass to the excerpt container:
add_action('the_excerpt','add_class_to_excerpt');
function add_class_to_excerpt( $excerpt ){
return '<div class="myclass">'.$excerpt.'</div>';
}
you don't have to put the_excerpt() inside a p tag, this is going to generate a new p tag contains the excerpt , all you have to do is to put the_excerpt() inside a div tag with your class name.
<div class="post-sumary">
<?php the_excerpt() ?>
</div>
Hi Guys Need help with this very badly.
Need to add shortcode to output in the area circled in white in the picture below.
And the input area is under video description. And from my understanding ive have confirmed that the name for that text area is description_value.
I have looked through every documentation and tried all filters and do_shortcode variations to no avail. Please help i have spent 3 days non stop doing this. Puting the codes in my function.php and so many others. It still does not parse [shortcodes] it just displays text "[shortcodes]". please refer to picture below
Thank you.
This is outputing on the page. I have
<div class="describe-feat">[postexpirator]</div>
This is in a file called grid-gallery.js
<h2><%= item.title %></h2></div><div class="view-gallery">\
<div class="describe-feat"><%=item.desc%></div>\
<% if(item.imgnum){ %><span class="item-num"><%= item.imgnum %></span><% } %>\
This is in custom post editor in wordpress admin area
<textarea name="description_value" class="option-textarea">[postexpirator]</textarea>
https://www.dropbox.com/s/almn09e1dwmeywb/shortcodxe.jpg
It's because, you are missing do_shortcode function for parsing shortcode.
Assuming you just want to target a single value, you could just do this inside the loop.
<?php echo ( do_shortcode( get_post_meta( $post->ID , 'Your textarea Key Name' , true ) ) ); ?>
If your post has multiple values for that custom field, then you can set the above to false.. and loop over the array...
<?php $values = do_shortcode( get_post_meta( $post->ID , 'Your textarea Key Name' , false ) ); ?>
<?php if($values && is_array($values)) : ?>
<?php foreach( $values as $meta) : ?>
<p><?php echo $meta ?></p>
<?php endforeach; ?>
<?php endif; ?>
Just want to add that if you won't use the_post() no shortcode will work,
I had this issue when trying to enable shortcode on CutomFields on a new page type, and nothing worked until activating WP loop with the_post() .
(sorry for my English) and I hope to explain!
I'm looking for a solution to display different output for a custom filed, named "cw". The my theme of much use in custom filed, so I created a function to simplify your calls:
/**
* Get custom field of the current page
* $type = string|int
*/
function my_getcustomfield($filedname, $page_current_id = NULL)
{
if($page_current_id==NULL)
$page_current_id = get_page_id();
$value = get_post_meta($page_current_id, $filedname, true);
return $value;
}
said this, I created the custom filed in my theme:
<?php $video_code = my_getcustomfield('cw',get_the_ID()); if(!empty($video_code)) : ?>
<div class="video_code"><?php echo $video_code; ?></div>
Since the custom value is a URL, type: http://127.0.0.1:4001/?f=cadbe2676d5108523f931a68eedb3582, I need to extract just the ID. using this technique PHP Regex to get youtube video ID?, I modified my custom filed in this way:
<?php $video_code = my_getcustomfield('cw',get_the_ID()); $url = $video_code; parse_str(parse_url($url, PHP_URL_QUERY )); if(isset($video_code[0])){ ?>
<div cacaolink="http://127.0.0.1:4001/?f=<?php echo $f; ?>"></div>
<?php } else { ?>
<?php echo 'Video n.d.'; ?></div>
<?php endif; } ?>
In this way everything works perfectly.
Now, the custom value can be those listed below:
<div cacaolink="http://127.0.0.1:4001/megavideo/megavideo.caml?videoid="></div>
<div cacaolink="http://127.0.0.1:4001/videobb/videobb.caml?videoid="></div>
<div cacaolink="http://127.0.0.1:4001/?f="></div>
**Finally here is the problem: How can I use an elseif according to the custom value?
any help is appreciated :)**
So what you need in short is extracting "video id" part from urls having one of 3 structures defined above. If I understood you right, you can just use the next code:
$video_id = preg_replace("/.*\?(videoid|f)=/", '', $customvalue);
Where $customvalue is the value extracted from your custom field with my_getcustomfield.
I'm using the advanced custom field plugin for Wordpress to show the results of checkboxes. I have what I want working, I just want to tidy up the code and add the following:
Remove the underscore from the social media tag (some kind of stripping out???).
If possible I'd like to show a comma after each "tag" but not if it's the last one.
Here's my test page, they're the blue "tags" under the discipline section.
Here's my code:
<?php
$catNames = array( 'branding','creative','development','exhibition','packaging','print','seo','social_media','usability','web','advertising','campaign','content','feasibility','publishing','research','strategy');
foreach($catNames as $name){
if(in_array($name, get_field('categories') )){
echo ''.strtoupper($name).'';
}
}
?>
Well it is pretty basic, you just have to do a loop. I could have write something better with more information... anyway this should do exactly what your code did but in a loop.
<?php
$catNames = array( 'branding','creative','development','exhibition','packaging','print','seo','social_media','usability','web','advertising','campaign','content','feasibility','publishing','research','strategy');
foreach($catNames as $name){
if(in_array($name, get_field('categories') )){ //I don't know what this is suppose to do
echo ''.strtoupper($name).'';
}
}
?>
Try this out:
<?php foreach( get_field('categories') as $category ): ?>
<?php echo ucwords($category) ?>
<?php endforeach; ?>
Ok this should be better
<?php
$catNames = array( 'branding','creative','development','exhibition','packaging','print','seo','social_media','usability','web','advertising','campaign','content','feasibility','publishing','research','strategy');
foreach($catNames as $name){
$theID = get_cat_ID($name); // get the ID of each category
echo ''.$theID->name.'';
}
?>
