And I think this simpler example would also work (replace the name of the custom field for featured in both examples):
$args = array (
'post_type' => 'nieuws',
'posts_per_page' => 1,
'orderby' => 'date',
'order' => 'DESC',
'meta_key' => 'custom_field_featured',
'meta_value' => 1,
'meta_compare' => '='
);
Veel succes 😉
Ok, so you want to only display the latest featured post, right?
You need to specify everything in the WP_Query – there’s no need for additional checking, if you only want one post. Use the meta_query, like this:
$args = array (
'post_type' => 'nieuws',
'posts_per_page' => 1,
'orderby' => 'date',
'order' => 'DESC',
'meta_query' => array(
array(
'key' => 'published',
'compare' => '=',
'value' => 1
)
),
);
You can find more examples of such queries here: http://www.advancedcustomfields.com/resources/how-to/how-to-query-posts-filtered-by-custom-field-values/
Well, either set the field “web_address” to “required” or check for existence of the field first before creating the paragraph with the link.
<?php if (get_field('web_address')) { ?>
// your code
<?php } ?>
And I don’t think the link is to the page URL when not filled out in the backend, it’s probably just empty. Try this:
echo get_field('web_address')
And you should get nothing for an empty field.
Hi,
in your example you’re checking the whole array of “featured”. Well, you’re already in the loop, so you’re already just working with a single post – and that post can either have the “featured” field on or off.
If you have the ‘featured’ field as a boolean (true/false), you can just edit your IF line to this:
<?php if(get_field('featured')) { ?>
And if you’re setting this field to something custom, just check it against that value:
<?php if(get_field('featured') == 'custom_value') { ?>
… ad as far as getting only one post (last) – fix your query, you can set “posts_per_page” to -1 to include all of the featured posts.
Well, create a page with a url like this
site.com/articles/article_with_gallery/page1
You assign the ACF gallery to “article_with_gallery” and you grab the last part of the URL (“page1”), substring the “page” away and you get the current position for the gallery (=show first image on this page).
Then you just display the first image from the gallery (it’s a simple array). For the next page, the next gallery image.
The navigation (previous/next gallery image) simply takes you to the next/previous page in the URL.
Well, you probably changed the default display of the date in ACF field settings. The php function strtotime cannot work with french dates.
Go to ACF field settings for date_picker and set it to YYYYMMDD
You’re not using the correct piece of code. If you want to use date_i18n, you have to set the language of your WordPress to English. This is a WP specific function.
To use the setlocale method, use this code inside the loop (the setlocale on top is OK):
// FIRST, SET THE WAY YOU WANT TO FORMAT DATE
// DETAILS HERE - https://php.net/strftime
$dateformatstring = "%A le %d %B, %Y";
// THEN, CONVERT THE FIELD FROM ACF TO UNIX TIMESTAMP
$unixtimestamp = strtotime(get_field('data_picker'));
// NOW ECHO THE ENGLISH DATE USING PHP'S strftime
echo strftime($dateformatstring, $unixtimestamp);
Ha 🙂 I thought you were trying to get it in french the whole time…
No big deal, just change the “setlocale” line of code to this:
setlocale(LC_ALL, array('en_GB.UTF8','en_GB','english'));
This sets up everything for UK english. If you want USA english:
setlocale(LC_ALL, array('en_US.UTF8','en_US','english'));
You can specify the values either in an array (like i did here) or as a sequence of string (as shown above with the french example).
And what is the current output of your code? What do you see in the browser?
Try this with the first (PHP) solution (replace the setlocale line):
setlocale (LC_ALL, 'fr-FR.utf8','fra');
There’s a bunch of locale codes … the top one works, but here’s a big discussion on this topic: Zut alors! Mon dieu! 🙂
You could setup your repeater field with a date and text field (see attached image). Then under the selected page / post type, just fill the repeater rows with dates (using date picker) and corresponding dates.
Then on the page (I’m using a custom post type “Movies” in this example – and a template “single-movie.php”) just put this PHP code to get “quote of the day”:
<?php
// GET TODAY'S DATE IN THE SAME FORMAT AS YOUR DATE SUB-FIELD
$today = date('Ymd'); // 20140503
// CHECK IF REPEATER HAS ROWS
if( have_rows('quote_of_the_day') ):
// LOOP TROUGH REPEATER ROWS
while ( have_rows('quote_of_the_day') ) : the_row();
// IF THE REPEATER SUB-FIELD MATCHES TODAY'S DATE, SHOW QUOTE SUB FIELD
if (get_sub_field('date') == $today) {
the_sub_field('quote');
}
endwhile;
endif;
?>
And if you have your blog set to french, you can just do these steps in the loop:
// FIRST, SET THE WAY YOU WANT TO FORMAT DATE
// DETAILS HERE - http://php.net/manual/en/function.date.php
$dateformatstring = "l d F, Y";
// THEN, CONVERT THE FIELD FROM ACF TO UNIX TIMESTAMP
$unixtimestamp = strtotime(get_field('data_picker'));
// NOW ECHO THE FRENCH DATE USING A WORDPRESS FUNCTION
echo date_i18n($dateformatstring, $unixtimestamp);
Ok, so let’s say ‘data_picker’ is your date field name in ACF. Set the locale before you go into the loop:
<?php setlocale(LC_ALL, 'fr_FR'); ?>
Then inside the loop do these steps:
// FIRST, SET THE WAY YOU WANT TO FORMAT DATE
// DETAILS HERE - https://php.net/strftime
$dateformatstring = "%A le %d %B, %Y";
// THEN, CONVERT THE FIELD FROM ACF TO UNIX TIMESTAMP
$unixtimestamp = strtotime(get_field('data_picker'));
// NOW ECHO THE FRENCH DATE USING PHP'S strftime
echo strftime($dateformatstring, $unixtimestamp);
Hi,
you can just create a dropdown field with the hour values and then use PHP to format it properly for display or calculations.
If you want minute-specific time, use a number field.
Hi,
I’m not sure what you’re asking/doing, but I think you should use the proper WordPress way to set this up.
Create a custom post type (Movies), then create a custom taxonomy (Genres), connect the taxonomy to the custom post type. You can use the CPT UI plugin for this, this Movies&Genres is literally the suggested example when you create your first CPT & Taxonomy.
Once you have this connected, you will automatically get “checkboxes” under your Movies posts and you can set your genres per movie.
When you want to loop trough a Genre, just use a WP_Query that filters by custom taxonomy. Here’s an example of that code:
$args = array(
'post_type' => 'movies',
'tax_query' => array(
array(
'taxonomy' => 'genres',
'field' => 'slug', //can be set to ID
'terms' => 'action' //if field is ID you can reference by cat/term number
)
)
);
$query = new WP_Query( $args );
Hi,
it’s simple, just create the variable first (to keep it clean) and then use it instead of the field name, like this:
$username = 'John'; // get this yourself
$dynamic_field_name = 'adwords_cost_for_' . $username;
echo the_field($dynamic_field_name, 'option');
There is nothing to activate – just start using it, it will work. The activation codes are a remainder from V3 if I remember correctly. It’s working fine without activation anyway.
ACF v5 will have an activation code though.
If you want to only display posts from a certain category id (or array of category ids), it’s just one extra line in the WP_Query arguments, like this:
$query = new WP_Query( 'cat=2,6,17,38' );
If you don’t want to use ID’s, you can do this:
$query = new WP_Query('category_name=staff');
You can of course combine this with the sorting by date from above – this is just one of the arguments.
You could use WP_Query for your basic loop (sorted by custom field ‘start_date’) like this:
$args = array(
'post_type' => 'your_custom_post_type',
'posts_per_page' => -1,
'meta_key' => 'start_date',
'orderby' => 'meta_value_num',
'order' => 'DESC'
);
$wp_query = new WP_Query( $args );
while( $wp_query->have_posts() )
{
$wp_query->the_post();
// now use get_field() for custom fields
}
Hi,
This is how you should use date_i18n with ACF:
$dateformatstring = "l d F, Y";
$unixtimestamp = strtotime(get_field('date_picker'));
echo date_i18n($dateformatstring, $unixtimestamp);
This depends on your blogs language setting. If you want to manually specify the locale in PHP, ignoring WordPress, you can do it like this:
setlocale(LC_ALL, 'fr_FR');
echo strftime("%A le %d %B, %Y");
//with day of the week = mercredi le 18 septembre, 2013
You need to be more specific. If the sliders are always a different size, you could add another ACF field for width and height and then use that field to set width and height in the template file.
For example:
<div class="flexcontainer">
<div id="first-slider" class="flexslider" style:"width:<?php echo get_field("slider_width") ?>">
<ul class="slides">
...
</ul>
</div>
</div>
If you have control over the javascript settings, just include the flexslider configuration inside the page (in a script tag) and again use ACF field for dimensions
There is also a strict javascript approach (when you don’t know the dimensions of images inside the slider).
var evenSliderHeight = function(slideContainer, slideItem) {
var slider_height = 0;
var $slider_slide = $(slideContainer).find(slideItem);
$slider_slide.each(function() {
var __height = $(this).outerHeight(true);
if ( slider_height < __height ) {
slider_height = __height;
}
});
$slider_slide.css('min-height', slider_height);
};
evenSliderHeight('.flexslider-container', '.slide');
You don’t need “the_row()” on the first line. The correct code would be:
<?php if(have_rows('activity_links')): ?>
<h3>Links</h3>
<ul>
<?php while(have_rows('activity_links')): the_row(); ?>
<li><a href="<?php echo the_sub_field('link_url'); ?>"><?php echo the_sub_field('name_for_link'); ?></a></li>
<?php endwhile; ?>
</ul>
<?php endif; ?>
Aha, sure, just use the WordPress function for formatting dates in different languages.
$dateformatstring = "l d F, Y";
$unixtimestamp = strtotime(get_field('date_picker'));
echo date_i18n($dateformatstring, $unixtimestamp);
This is dependent on your blog language setting. More info here: http://codex.wordpress.org/Function_Reference/date_i18n
If you can’t set blog language to french, you can also do it with PHP only.
setlocale(LC_ALL, 'fr_FR');
echo strftime("%A %e %B %Y");
Another example with day of week and month (french):
setlocale(LC_ALL, 'fr_FR');
echo strftime("%A le %d %B, %Y");
//with day of the week = mercredi le 18 septembre, 2013
Now it’s just a matter of php-array trickery to generate this query from array.
// GET RECIPES THAT HAVE A RELATIONSHIP TO PRODUCTS ON THE CURRENT PAGE - dynamically
$recipes_dynamic_meta_query = array(
'post_type' => 'recipes',
'meta_query' => array(
'relation' => 'OR'
)
);
foreach($product_ids as $product_id) {
array_push($recipes_dynamic_meta_query['meta_query'], array(
'key' => 'products_under_recipes',
'value' => '"' . $product_id . '"',
'compare' => 'LIKE'
));
}
Run this string trough get_posts and you’re set!
$recipes_manual = get_posts($recipes_dynamic_meta_query);
