Get The Title and Permalink of a post From Relationship Field

I’m not to familiar with Genesis, so I don’t know if get_the_id() and $post->ID will work in this context. The method described in that tutorial will work, if the ID is set properly.

In that tutorial, I show you how to get the ID of a related post into a variable $id. You can pass that to get_the_title() and get_the_permalink(). If that’s not working than I suspect that the problem is with how you are getting the ID when building your original books Pods object.

Thanks, Josh

I’ll try a little more.

A guess the genesis hook is not the problem, it is very flexible and i did a var_dump which gave me the following results:

array(23) { ["ID"]=> string(4) "3194" ["post_author"]=> string(1) "1" ["post_date"]=> string(19) "2014-06-09 10:02:49" ["post_date_gmt"]=> string(19) "2014-06-09 13:02:49" ["post_content"]=> string(14) "Escritor Teste" ["post_title"]=> string(14) "Escritor Teste" ["post_excerpt"]=> string(0) "" ["post_status"]=> string(7) "publish" ["comment_status"]=> string(6) "closed" ["ping_status"]=> string(6) "closed" ["post_password"]=> string(0) "" ["post_name"]=> string(14) "escritor-teste" ["to_ping"]=> string(0) "" ["pinged"]=> string(0) "" ["post_modified"]=> string(19) "2014-06-09 13:03:48" ["post_modified_gmt"]=> string(19) "2014-06-09 16:03:48" ["post_content_filtered"]=> string(0) "" ["post_parent"]=> string(1) "0" ["guid"]=> string(58) "https://fuvestibular.com.br/?post_type=escritor&p=3194" ["menu_order"]=> string(1) "0" ["post_type"]=> string(8) "escritor" ["post_mime_type"]=> string(0) "" ["comment_count"]=> string(1) "0" }

I copied all the code from the tutorial and placed it inside my custom post type template replacing the pod name and the custom field name, as follows:

<?php
    	//get Pods object for current post
    	$pod = pods( 'livro', get_the_id() );
	//get the value for the relationship field
	$related = $pod->field( 'autor_do_livro' );
	//loop through related field, creating links to their own pages
	//only if there is anything to loop through
	if ( ! empty( $related ) ) {
		foreach ( $related as $rel ) {
			//get id for related post and put in ID
			//for advanced content types use $id = $rel[ 'id' ];
			$id = $rel[ 'ID' ];
			//show the related post name as link
			echo '<a href="'.get_permalink($id).'">'.get_the_title( $id ).'</a>';
			//get the value for some_field in related post and echo it
			$someField = get_post_meta( $id, 'imagem_do_livro', true );
			echo $someField;
		} //end of foreach
	} //endif ! empty ( $related )

genesis();

?>

“livro” is my custom post type created with pods plugins and “autor_do_livro” is the Relationship Field related to the author custom post type.

Strangely the links i get are from my contact page and the actual page with its title… you can see it the top of this page: https://fuvestibular.com.br/livro/sentimento-mundo/

they are at showing at the top of the page because i am not hooking the code anywhere since i am trying to use the raw code from the example to see how i can make it work.

Any thought?

Thanks for providing more info. Can you tell me where you generated that var_dump() from? It looks like the expected responses for a related field. As you can see, there is a key ‘ID’ that corresponds to the post ID, that can be used for functions like get_the_title().

I’m not sure where on the page I should look to see the results of the code you showed.

I put the var dump back again,

This is the code of single-livro.php which generates this page: https://fuvestibular.com.br/livro/sentimento-mundo/

<?php
    	//get Pods object for current post
    	$pod = pods( 'livro', get_the_id() );
	//get the value for the relationship field
	$related = $pod->field( 'autor_do_livro' );
	//loop through related field, creating links to their own pages
	//only if there is anything to loop through
	if ( ! empty( $related ) ) {
		foreach ( $related as $rel ) {
			//get id for related post and put in ID
			//for advanced content types use $id = $rel[ 'id' ];
			$id = $rel[ 'ID' ];
			//show the related post name as link
			echo '<a href="'.get_permalink($id).'">'.get_the_title( $id ).'</a>';
			//get the value for some_field in related post and echo it
			$someField = get_post_meta( $id, 'imagem_do_livro', true );
			echo $someField;
		} //end of foreach
	} //endif ! empty ( $related )

$a = $related;
var_dump ($a);

genesis();

?>

The page title of the related author page (Escritor Teste) and the other stuff looks ok in the responses, but as you can see, the code is generating unexpected links at the top of the page.

I have no clue about whats going on, your help is more than appreciated!

I’m seeing array(0) { } as the output. You should back up and ensure that $pod = pods( 'livro', get_the_id() ); is working properly. I’d do:

var_dump( get_the_id() );
$pod = pods( 'livro', get_the_id() );
var_Dump( $pod->id() );

Both of those var_dumps should give you the same output. If not then that’s the problem.

By the way, doing this in the front-end is a really inefficient way of working. I’d recommend using the debug console plugin, as I detail in the second half of this article under the header “Tools for Detective Work”.

Well, i am not a php guy and all i can do is thought trial and error…

Nevertheless, i removed the var_dump from the CPT template and tried to follow your instructions. I got the result you can see in this picture : https://fuvestibular.com.br/wp-content/uploads/2014/06/Screen-Shot-2014-06-09-at-6.33.29-PM.png

I am with debug mode enabled right now, and a new strange message with links appeared it that page: https://fuvestibular.com.br/livro/sentimento-mundo/ maybe if you can take a look you might understand something…

This is the pod livro custom type and i have single-livro.php inside my theme folder, the code of this file is exactly this right now:

<?php
    	//get Pods object for current post
    	$pod = pods( 'livro', get_the_id() );
	//get the value for the relationship field
	$related = $pod->field( 'autor_do_livro' );
	//loop through related field, creating links to their own pages
	//only if there is anything to loop through
	if ( ! empty( $related ) ) {
		foreach ( $related as $rel ) {
			//get id for related post and put in ID
			//for advanced content types use $id = $rel[ 'id' ];
			$id = $rel[ 'ID' ];
			//show the related post name as link
			echo '<a href="'.get_permalink($id).'">'.get_the_title( $id ).'</a>';
			//get the value for some_field in related post and echo it
			$someField = get_post_meta( $id, 'imagem_do_livro', true );
			echo $someField;
		} //end of foreach
	} //endif ! empty ( $related )

genesis();

?>

single-livro.php are you doing this inside of the WordPress loop? If not, replace $pod = pods( 'livro', get_the_id() ); with global $post; $pod = pods( 'livro', $post->ID ); as get_the_id() will not work outside of the loop.

I just created the “livro” custom post type with pods and also created a file name single-livro.php inside my theme folder.

The template file is working properly with this pod since the stuff i place inside it reflects on the “livro” post type output. I could display the post custom fields with no problem.

I dont know why the single-livro.php appeared on the debug message. This post type uses single-livro.php, thats where i just pasted the code from the tutorial replacing my pods name and the relationship field it uses and that is related to the custom post i want to get the title and url.

Also replaced the line you mentioned but with no success.

Theres a message:

NOTICE: wp-content/themes/fuvestibular/single-livro.php:12 – Uninitialized string offset: 0

The line 12 insite that custom post template is

$id = $rel[ 'ID' ];

Should be something wrong with it?

I would assume that if you var_dump $related it is an associative array of one related item’s fields, not a dimensional array where index is an associative array of related items field. The var_dump you showed above is an example of the former, but you need the later. TO address this, before the loop, after the line if ( ! empty( $related ) ) { do something like this to check that this is the case and if so put the array into a state that can be properly looped through, with something like this:

if ( key( $related ) == 'ID' ) {
$related[0] = $related;
}

No success… =(

I really want to use this plugin. I am migrating from wp-types to pods because it has more capabilities and seems to be much better, but it is also more technical…

With types i was able to get it by simply using this:

$cptb_parent_id = wpcf_pr_post_get_belongs(get_the_ID(),'escritores');
   $author_name = get_the_title($cptb_parent_id);
   $author_url = post_permalink($cptb_parent_id);

I already learned how to do all the other stuff with pods and i just need to get it working now, but this topic is seeming something beyond my powers.

I know its a little to much to ask, but if i give you my credentials: would you check this out for me?

I would be grateful for the rest of my life!

well, dont mind…

I decided to test it out on another host and and the stuff worked out like magic.

The problem seems to be with synthesis managed host, already sent a ticket and now i am just waiting.

I will report back when i hear from them.

I got this as an answer:

You will want to verify that the code does not require the exec() / exec.php or url_fopen functions, as both of those have been disabled on Synthesis hosting for security reasons.

We do support CURL as an alternative to url_fopen.

Could you confirm if that is the case with the code i am trying to use?

Thanks for your patience and for checking in another environment. That was going to be my next suggestion, as this was starting to make no sense.

I did a search and do not see either of those functions being used. Can you please share (in a gist or a pastebin) the debug information for both of the environments you are working in? You can get this info from Pods Admin->Debug. I’d like to be able to see if there is a difference between the two, as well as with my test environment, that might be responsible for this not working on Synthesis.
