• In reply to Delete Gallery Images when Deleting Post

• July 11, 2013 at 2:41 pm

Hi @goodwebsites

The only way to do this is to hook into the save function of the gallery field (before ACF saves the new value) and compare the previous and new values.

From there you can delete the attachment post records you need to.

Use the above search to find more info on the acf/update_value filter which you can use to hook into the gallery field save function.

The rest should be straight forward but will require time and debugging skills.

Good luck

• In reply to ACF and WPML?

• July 11, 2013 at 1:19 pm

Hi @Athen

Yes, ACF is compatible with WPML.

You can translate pages independently to have different custom field values.

Does this solve the question or is there something specific you want to know?

Also, to clarify, the value I’m getting back for the presenter in that $presenter_data query is a serialized item like this:

a:1{i:0;s:2:"71";}

71 is the ID I’m trying to get. I realize I could use some PHP to manipulate this, just seems like there must be a better way.

• In reply to Displaying Fields from Post Category or Subcategory

• July 11, 2013 at 12:14 pm

Thanks for your quick reply. There’s probably something I’m not understanding about $term_id. I have a regular WP post category of “stories-by-state” which has subcategories of each state (alabama, alaska, etc.). I don’t think the fact that I’m retrieving subcategory info has any effect on the outcome.

Given your instruction, I would have something like the folowing:

the_field('test_field', 'alabama_' . $term_id);

or

the_field('test_field', 'alabama_16');

where 16 is the the number I get from the ur:l /wp-admin/edit-tags.php?action=edit&taxonomy=category&tag_ID=16&post_type=post

Neither worked and I”m not 100% sure how to pull $term_id.

• In reply to How to Query Relationship Field

• July 11, 2013 at 11:57 am

So, later on, I realized that this is not the right way to go about it. Really what I want is a subset of a CPT called “staff.” I want to get the staff who are presenters on my CPT called “presentations.”

Therefore, it seems like I should do a query on “staff” but just get the ones whose ID is used in the presentations. Right?

$args = array(
	'post_type'	=> 'staff-members',
	'posts_per_page'     => -1,					
	'post_status' => 'publish',
	'order' => 'ASC',
	'orderby' => 'title',
	'post__in' => $presenter_id_list												
);

However, this starts getting way more complicated than it seems like it should… in order to get the $presentation_id_list data, I can get the distinct list of presenters here:

$presenter_data = $wpdb->get_col( 
"SELECT DISTINCT wp_postmeta.meta_value FROM wp_posts 
INNER JOIN wp_postmeta ON (wp_posts.ID = wp_postmeta.post_id)
WHERE 1=1 AND wp_posts.post_type = 'presentations' AND (wp_posts.post_status = 'publish') AND (wp_postmeta.meta_key = 'presenters' ) 
GROUP BY wp_posts.ID ");

But that gives me an array of the serialized “presenter” relationship field. How do I get at the ID in that relationship field??? This seems like it is getting way more complicated than it needs to be. Am I missing something?

Thanks!

• In reply to Get field key via script

• July 11, 2013 at 9:05 am

I’ve also been looking for a way to get the key from a name. The best solution I’ve come up with is adding a function which does a switch/case on the field name and applies a filter to return the key. However, it does require that you manually code a case/return/break for each field (probably not practical if you’ve got more than a few dozen fields).

Code here: https://gist.github.com/wells5609/5971010

• In reply to How to Query Relationship Field

• July 11, 2013 at 8:39 am

@relish27

Change the “orderby” arg to ‘orderby’ => ‘meta_value’ and then specify ‘meta_key’ => ‘presenter’ (rather than ‘meta_value’ => ‘presenter’). This will order the query results by the meta_value of ‘presenter’.

It sounds like you’re trying to also query posts with a specific ‘presenter’ value. If so, add to the $args array:

'meta_query' => array(
  array(
    'key' => 'presenter',
    'value' => '"' . $presenter_value . '"',
    'compare' => 'LIKE',
  )
)

• In reply to Frontend WYSIWYG Problems

• July 11, 2013 at 1:44 am

Maybe it is worth more information, but I understand that “live” triggers are able to be used on DOM elements populated after the page has loaded. Likewise, I have set up some working code in order to close this created popup when the newly created ACF form is submitted.

Also here is a helpful example for other users viewing this forum to submit their acf form with jQuery – works very nicely.

$( "#acf-ajax-form" ).live( "submit", function( event ) {
    event.preventDefault();

    $(this).find('input[type=submit]').attr("disabled", true).val("Processing...");

    var formData = $(this).serialize();
    var formUrl = formData.return;

    $.post(formUrl, formData, function(response) {
        // Close the popup container
        $('#my-popup-container').foundation('reveal', 'close' );

        // Clear the HTML
        $('#my-popup-container').html('');
    });
});

Is there a way in which we might perform the jQuery trigger that you suggested above (acf/setup_fields) to mimic the “live” event?

• In reply to Meta Key Values in Custom Field Dropdown

• July 11, 2013 at 12:42 am

1 – For all of the custom fields that I control the naming of, I prefixed the key with an underscore (i.e. “_my_custom_field”). This prevents them from being displayed in WordPress’ custom fields drop-down list.

2 – For the custom fields that ACF automatically generates (i.e. when using tabs, ACF uses the “field_51” prefix on the site that I’m working on), I wrote some PHP:

if(!function_exists(‘kc_hide_meta_keys_start’)){
function kc_hide_meta_keys_start( $num ){
add_filter( ‘query’, ‘kc_hide_meta_keys_filter’ );
return $num;
}
add_filter( ‘postmeta_form_limit’, ‘kc_hide_meta_keys_start’ );
}
if(!function_exists(‘kc_hide_meta_keys_filter’)){
function kc_hide_meta_keys_filter( $query ){
remove_filter( current_filter(), __FUNCTION__ );
// Match keys beginning with field_51
$where = “WHERE meta_key NOT LIKE(‘field_51%’);
$find = “GROUP BY”;
$query = str_replace( $find, “$where\n$find”, $query );
return $query;
}
}

• In reply to Attach images created in front end form to custom post

• July 10, 2013 at 4:56 pm

Hi Elliot,
First off i’d like to thank you for providing this wonderful plugin. It has done wonders for me so far.

I found a dirty hack of using the ‘pre-save-post’ filter function to get the attachment ID and programmatically change the post parent. The function is:

function attachment_change_parent($aid,$pid) {
	global $wpdb;
	$query = "UPDATE {$wpdb->prefix}posts
		SET post_parent = $pid
		WHERE ID = $aid";
	return ($wpdb->query( $wpdb->prepare($query) )) ? true : false;
} 

It works so far but it is not the best option. I will eagerly await your update on this.

Otherwise thanks again. Keep up the good hard work sir!

No JS errors on page. Success AJAX callback function does indeed run. (Is there any way to print JS errors from the AJAX request url?)

Matched ID in JS acf/setup_fileds trigger to the $options[‘form_attributes’][‘id’] from when setting up form.

Ran code after HTML was returned as well as attempted a 5000 milisecond timeout function to double check. (Not really necessary since the HTMl is returned before the AJAX success callback function is run).

If you are familiar with Zurb Foundation, I am using this JS to return the HTML within the container DOM:

LINK

$(".reveal-popup-button").click(function(event) {
    event.preventDefault();

    $("#my-popup-container").foundation("reveal", "open", {
        url: ajaxurl,
        action: "my_popup_ajax",
        type: "POST",
        success: function(data) {
            $(document).trigger("acf/setup_fields", $("#acf-ajax-form"));
        },
        error: function() {
        }
    });
});

And here is my WP AJAX action:

function my_popup_ajax_callback() {
    echo "<div id="my-popup-content">";
        $args = array(
            "post_title" => "Draft",
            "post_status" => "draft",
        );

        $id = wp_insert_post( $args );

        $html = my_popup_build_acf_form( $id, 12 );

        echo $html;

    echo "</div>";
    die();
}
add_action( "wp_ajax_my_popup_ajax", "my_popup_ajax_callback" );

And the function that returns the form’s HTML:

function my_popup_build_acf_form( $id, $fieldgroup ) {
    $options = array(
        "post_id" => $id,
        "field_groups" => array( $fieldgroup ),
        "form_attributes" => array(
            "id" => "acf-ajax-form"
        ),
        "return" => add_query_arg( "updated", "true", get_permalink( $id ) ),
        "html_field_open" => "<div>",
        "html_field_close" => "</div>",
        "html_before_fields" => "",
        "html_after_fields" => "",
        "submit_value" => "Submit",
        "updated_message" => "Post updated.",
    );

    ob_start();
    acf_form( $options );
    return ob_get_clean();
}

$(document).trigger('acf/setup_fields', $('#id-of-container'));

AND

$(document).trigger('acf/setup_fields', $('#id-of-acf-form'));

Neither of those worked… I will be honest and say that I would be considered a newbie at jQuery, so perhaps you could offer any more guidance? Of course we all thank you for the helpful support in these forums… it is definitely gracious and helpful.

Hi @realnsleo

Thanks for the question. The WP uploader uses a JS variable stored in acf.o.post_id to set the ‘attached to’ data of an image.

I’m not sure you would be able to edit this to the new post_id as the new post_id has not yet been created…

I will soon be releasing a new field for ACF which is a basic file input field and will allow you to bypass this issue completely.

Until then, I’m not sure what the solution is…

Hi @xranerx

A simple counter can be used to limit the fields. I have taken the liberty of neatening your code and adding in a limiter of 4 rows:

<?php if(get_field('show_dates', 'option')):
	
	$i = 0;
	
	?>
	<ul>
		<?php while( has_sub_field('show_dates', 'option') ): 
			
			$i++;
			
			if( $i > 4 )
			{
				break;
			}
			
			?>
			<li><a href="<?php site_url(); ?>/show-dates"><?php the_sub_field('show_date_table_city');?></a></li>				 
		<?php endwhile; ?>
	</ul>	 
<?php else: ?>
	<p>Show dates to be announced soon.</p>
<?php endif; ?>

Please continue to practice your PHP and write clean code that does not have mixed styles.

Good luck

Hi @coalesce

This should not be publishing the changes. Can you post which version of ACF you are using?

I believe this was an issue with pre v4, but v4 did fix this.
