• In reply to update_post_meta() and gallery field

If I add images to the gallery field via admin panel (not directly to db), this parameter equals to “2” or “3” or “4” but why precisely?

• In reply to dynamically generate subfield content

• February 14, 2015 at 8:17 pm

This has been bugging me for quite a while, but I think I’ve finally cracked it. It was almost disappointingly simple in the end – $value needs to be an array.

add_filter('acf/load_value/key=field_54aa5b3b008b0',  'afc_load_my_repeater_value', 10, 3);
function afc_load_my_repeater_value($value, $post_id, $field) {
	if ($post_id === false) {
		$value	= array();
		$value[] = array(
			field_54aa5beb008b1 => 'Hours',
			field_54aa5c25008b2 => 1
		);
		$value[] = array(
			field_54aa5beb008b1 => 'Minutes'
		);
		$value[] = array(
			field_54aa5beb008b1 => 'Seconds'
		);
	}
	return $value;
}

This case is pretty straight forward; I have one repeater field field_54aa5b3b008b0 that has two text fields inside it (field_54aa5beb008b1 and field_54aa5c25008b2). I imagine the same setup will apply to more in-depth scenarios as well with some tweaking.

Step 1. Hook into acf/load_value on your repeater field. You can use type/key/name as desired here.

Step 2. Check if the $post_id is set or not. If you want to modify the values of existing posts as well you wouldn’t need to, but here I want to set default values for new posts only.

Step 3. Set $value to your array of default values. Above, I have 3 rows by default on new posts. Each row has two values – ‘unit of time’ and ‘amount of time’. The ‘unit of time’ values are set to “Hours”, “Minutes” and “Seconds”. The ‘amount of time’ value on the “Hours” row I have set default to 1. In the other rows, I didn’t want the second value to be set by default, so it’s omitted – if omitted, ACF uses the default value set in the admin (or just blank).

Step 4. Return the $value. Make sure you always return it – even if you haven’t modified it.

———– NOTES
– I’m using ACF Pro 5.1.8, but it should work in other versions as well (using the proper hooks as needed).
– The sub fields appear to be required to the the exact field key – field name and type haven’t worked for me.
– Above, I’m setting a static set of values as my defaults. You could certainly call a function or otherwise dynamically load an array into $value from elsewhere as well – just need to make sure it uses the key for sub fields.
– If you’re not sure how the array should be set up, just print out an array from an existing repeater in the wp-admin like this:

add_filter('acf/load_value/key=field_54aa5b3b008b0',  'afc_load_my_repeater_value', 10, 3);
function afc_load_my_repeater_value($value, $post_id, $field) {
	echo print_r($value);
	return $value;
}

This will print out the repeater value from an existing post. Save the post with some rows in your repeater and you’ll see a guide of how to set up the array of defaults.

• In reply to ACF gallery + simple lightbox problem

• February 14, 2015 at 8:58 am

I understand it has to be looped through slb_activate() but how? It’s not explained anywhere to dummies like me.

I have my gallery displaying using the following code, but the lightbox doesn’t do a thing.

$images = get_sub_field('sc_images');

if( $images ): ?>
<ul>

     <?php foreach( $images as $image ): ?>
     <li>
           <a href="<?php echo $image['url']; ?>">
	        <img src="<?php echo $image['sizes']['thumbnail']; ?>" alt="<?php echo $image['alt']; ?>" />
	   </a>
           <p><?php echo $image['caption']; ?></p>
     </li>

</ul>

• In reply to ACF relationship field not being populated in admin with custom post type

• February 14, 2015 at 4:47 am

This is an old post, but I came across exactly the same problem with ACF 4.4.0. I have two relationship fields assigned to my normal WP posts.

One of the relationship fields displays a list of all WP posts and has no taxonomy restrictions. The posts appear as expected in the relationship selection area.

The other relationship field is supposed to display a list of custom post types restricted by a custom taxonomy. Nothing appears in this relationship selection area; it’s completely blank. The field itself appears, but the left pane is empty. Removing the taxonomy restriction did not fix the problem – the only way I could get anything to appear in the left pane was to choose either WP posts or WP pages as the post type.

This appears to be a bug, but considering the lack of similar reports (I have been unable to find much online), maybe it’s a unique situation.

I upgraded to 5.0 and that fixed the problem – kind of. The left pane correctly populates with the custom post type, but the search feature does not work. Regardless of what I enter, I get “no matches found”. I describe this problem in this related ticket:

http://support.advancedcustomfields.com/forums/topic/search-not-working-on-relationship-field-in-wordpress-4-0/#post-22436

So, upgrading to ACF 5.0 fixes the issue of the field not being populated, but now search does not work with custom post types.

• In reply to First image in gallery bigger

• February 13, 2015 at 7:25 pm

i would recommend do something like that:

<?php 
$images = get_field('gallery');
$img_count=1;
if( $images ): ?>
    
        <?php foreach( $images as $image ):
if ($img_count == 1) { ?>
<div class="large">
                <a rel="gallery" href="<?php echo $image['url']; ?>">
                     <img src="<?php echo $image['sizes']['large']; ?>" alt="<?php echo $image['alt']; ?>" />
                </a>                
            </div>
<?php } else {?>
            <div class="thumb">
                <a rel="gallery" href="<?php echo $image['url']; ?>">
                     <img src="<?php echo $image['sizes']['thumbnail']; ?>" alt="<?php echo $image['alt']; ?>" />
                </a>                
            </div>
<?php } 
$img_count++; ?>
        <?php endforeach; ?>    
<?php endif; ?>

instead of trying to use css only.
you probably need to add a popup-script like fancybox too, to get a result like your example.

(with help of css3, it should be possible for new browsers, to do a css only solution. look at :first-of-type for example, but i would not recommend that)

• In reply to Repeater Field inside Flexible Content

• February 13, 2015 at 6:48 pm

sure you can have repeater inside flexible field.
from original docs here

Nested Loop

<?php

// check if the flexible content field has rows of data
if( have_rows('flexible_content_field_name') ):

 	// loop through the rows of data
    while ( have_rows('flexible_content_field_name') ) : the_row();

		// check current row layout
        if( get_row_layout() == 'gallery' ):

        	// check if the nested repeater field has rows of data
        	if( have_rows('images') ):

			 	echo '<ul>';

			 	// loop through the rows of data
			    while ( have_rows('images') ) : the_row();

					$image = get_sub_field('image');

					echo '<li><img src="' . $image['url'] . '" alt="' . $image['alt'] . '" /></li>';

				endwhile;

				echo '</ul>';

			endif;

        endif;

    endwhile;

else :

    // no layouts found

endif;

?>

basically it is nothing very special. it is just a (repeater) loop inside a (flexible content) loop

@paaljoachim if you don’t open <article> remove the closing </article>, and remove a closing </div> too. it looks like my original code has also one to much.

replace </div></div></article> with </div> else it looks fine

or add something like that <article itemtype="http://schema.org/CreativeWork" itemscope="itemscope" class="post-<?php print $pageid; ?> page type-page status-publish entry"><div class="entry-content" itemprop="text"> above <div class="movie-content">

• In reply to Shortcode doesn't work in Page

• February 12, 2015 at 6:44 pm

it depends if you have a post for every user or not.
if yes, than it may work with this shortcode [acf field="sms2" post_id="user_1"] of course only for user 1

if you wish to have 1 post and show value depends on user, i think, you need a custom template for that post

• In reply to How do I display Flexible Content inside a Repeater Field

• February 12, 2015 at 9:46 am

I figured out a work around

$feature is the parent repeater field.

<?php $media = $feature['feature_media']; if($media): ?>

			<div id="feature_media">     	
			<?php 
				foreach($media as $key=>$row) {
					
					$layout = $row['acf_fc_layout'];
                	
					if($layout == 'static_image'):
						$image = $row['image'];
        				echo '<img src="'.$image['url'].'">';
                	
					elseif($layout == 'slideshow'):
						$slides = $row['images'];
						if($slides):
							echo '<ul class="slides">';
							foreach($slides as $slide) {
								echo '<img src="'.$slide['url'].'">';
							}
							echo '</ul>';
						endif;
                
					elseif($layout == 'video'):
						$embedcode =  $row['embed_code'];
    					echo $embedcode;
						
					endif;
                	
				} // end each row

			?>
        	</div>     
		<?php endif; // end if media ?>

Not sure this is the right approach but at least it worked.

• In reply to Admin-only visibility on fields

• February 12, 2015 at 3:18 am

Thanks for the link, but what I meant was that a field would only be visible to users logged in as administrators, not that a field would appear on the administrator profile page.

I know that ACF doesn’t do view counting ;). It was a quick example to illustrate a use for an admin-only visibility field.

• In reply to Shortcode doesn't work in Page

• February 12, 2015 at 2:17 am

Ok, I might be wrong, but I don’t think the shortcode will let you retrieve values from a user. A shortcode only let you indicate field name and post_id.

But this might point you out in the right direction:
http://www.advancedcustomfields.com/resources/how-to-get-values-from-a-user/

The documentation says:

All the API functions can be used with a user, however, a second parameter is required to target the user ID. This is similar to passing through a post_id to target a specific post object.

The $post_id needed is a string containing “user” + the user ID in this format: “user_$UserID”

You will need to specifiy the user_ID for that. But as I said before, I dont think that’s available in a shortcode.

• In reply to Shortcode doesn't work in Page

@hpctech the answer is simple: In your case the ACF is empty, because there is no place so far where you are filling the information that this field should be displaying. The ACF is a “container”, but from where is this container grabbing the information that should be displayed?

Let’s say you use a post to do this. If I am not wrong in your current settings, if you go to Posts > Add new, you will see the new sms2 field you created (below the content editor). Fill that text area with something, a number, whatever, and save it, then in the page where you are using the shortcode write [acf field="sms2"] or [acf field="sms2" post_id="524"] and replace 524 for the post-ID from where you want to grab this info.

1. Created custom field as shown in the above screenshot

4. clicked publish… Voila nothing appeared!

• In reply to ACF in attachment-single.php

• February 11, 2015 at 10:03 pm

Ok, now it’s clearer.

My question would be: if you just need to output text in a WYSIWYG field, why dont you just write the text in the_content() and attach the audio to that field as well? Why two fields?

But try this code and tell me if it works:

<div class="chapo">
	<?php the_field('chapo'); ?>
</div>

<div class="content">
	<?php the_content(); ?>
</div>

If it doesn’t, can you inspect the html with chrome or firefox and tell me what’s being displayed inside these divs?

• In reply to ACF in attachment-single.php

• February 11, 2015 at 7:27 pm

1) what are you puting in the chapo field.
<p>WYSIWYG content from get field</p>

2) what are you putting in the content editor
<audio><!-- attachment audio stuff... --></audio>
(this really is the media file)

3) where / how is the attachment being added
From the media library (wp-admin/media-new.php)

4) whats the code in your php file
page.php

<?php
get_header();

while (have_posts())
{
  the_post();

  if ( get_post_type() == 'attachment' )
  {
    get_template_part( 'attachment', 'single' );
  }
  else
  {
    get_template_part( 'content', 'page' );
  }
}

get_footer();

attachment-single.php

<div class="chapo">
  <?php
  if ( get_field( 'chapo' ) )
  { ?>
    <?php echo get_field( 'chapo' ); ?>
  <?php
  } ?>
</div>
<div class="content">
  <?php the_content(); ?>
</div>

5) what should be the desired output?

<div class="chapo"><p>WYSIWYG content from get field</p></div>
<div class="content"><audio><!-- attachment audio stuff... --></audio></div>

6. What actually appears?

<div class="chapo"><audio><!-- attachment audio stuff... --></audio><p>WYSIWYG content from get field</p></div>
<div class="content"><audio><!-- attachment audio stuff... --></audio></div>

Note: This happens with any media file, not just audio.

• In reply to Autoload options

• February 11, 2015 at 11:05 am

Bump. Custom fields stored as options are still generating multiple SQL queries per get_field call due to the lack of autoload which is very bad.

If a per-option setting isn’t possible, then the plugin should go back to defaulting to autoload.

i use them to update post_title or post_content with values that come from get_field

or the save action: (all you need is a hidden field with name “totalprice“)

Hi thank you for the suggestion.

The issue is that on the php side while I’am saving the new value I need to get the values of other ACF fields, something like

$total = get_field(‘price’) * get_field(‘qty’);
update_field(‘total’, $total);

BUT the issue is that I cannot use get_field(‘xxxx’) as the field xxx is not yet saved in the DB (as is a new post).

use a hidden field and update value of it based on the other values.

may use that: https://github.com/folbert/acf-hidden (out of this thread)

than use update_field or update_value to save it into DB
