Can’t get values from related post

Hello @berttervoert

Could you share the code you use in your template?

Cheers, Jory

The code I use in my template:

<?php
/*
  Template Name:      wdtv upcoming programm
  Template Post Type: post, page, fietsroutes, agenda_fietsroutes
  Description:        Template om de komende fietsroutes van het programma

*/
?>
<div class="wdtv_club_titel">Programma aankomende weken:</div>
<?php
//  Get the weeknumber for the current week and the next week
$cur_week_nr = date('W');
$nxt_week_nr = ($cur_week_nr + 1);

//  Set up the parameters for pods::find
$params = array(
  'where' => 'week.meta_value = "' . $cur_week_nr . '" OR week.meta_value = "' . $nxt_week_nr . '"',
  'limit' => -1
);

//  Run the find
$wdtv_pods = pods( 'agenda_fietsroutes', $params );

if ( $wdtv_pods->total() > 0 ) {
  while ( $wdtv_pods->fetch() ) {
    $route          = $wdtv_pods->display( 'titel' );
    $datum          = $wdtv_pods->display( 'datum' );
    $tijd_vertrek   = $wdtv_pods->display( 'vertrektijd' );
    $plaats_vertrek = $wdtv_pods->display( 'vertrekplaats' );

    $wdtv_pod       = pods( 'agenda_fietsroute', get_the_id() );
    $wdtv_releated  = $wdtv_pod->field( 'relationship_field' );
    if ( !empty ( $wdtv_related ) ) {
      foreach ( $wdtv_related as $wdtv_rel ) {
        $wdtv_id = $wdtv_rel[ 'ID' ];
      }
    }

    ?>
      <div id="wdtv_programma_container">

      </div><?php
  }
}
else {
  ?>er staan geen activiteiten gepland voor de komende weken.<?php

I also exported the two pods:

I’ve got 3 questions/remarks about the code in the template:
1) should get_the_id() return a number? When I echoed it, it show the post-type, not a number.
2) The variable $wdtv_related is empty, so the foreach part doesn’t get executed.
3) the last part of the template (the divs) isn’t correct at the moment, it needs to be altered, but that’s the result of many tries to get the php part working.

Hope you have enough information to give any suggestions.
Thanks in advance,
Bert.

Hello @berttervoert

1) should get_the_id() return a number? When I echoed it, it show the post-type, not a number.

It should indeed return the current post ID. Assuming you are on a post page or within the loop.

2) The variable $wdtv_related is empty, so the foreach part doesn’t get executed.

This is quite understandable.
What is your Pod called exactly? agenda_fietsroute or agenda_fietsroutes?
You’ve used both so that cannot be right.

3) the last part of the template (the divs) isn’t correct at the moment, it needs to be altered, but that’s the result of many tries to get the php part working.

Okidoki!

Cheers, Jory

Hello @jory,

ad 2) that is a typo indeed. Changed it to agenda_fietsroutes, which is the correct name for the pod.

the part of the code that doesn’t seem to work is now:

    //  Get additional info from related pod
    $wdtv_pod       = pods( 'agenda_fietsroutes', get_the_id() );
    echo $wdtv_pod;
    $wdtv_releated  = $wdtv_pod->field( 'relationship_field' );
    if ( !empty ( $wdtv_related ) ) {
      foreach ( $wdtv_related as $wdtv_rel ) {
        $wdtv_id = $wdtv_rel[ 'ID' ];
      }
    }
    else {
      echo " geen relaties gevonden";
    }
    ?>

The line: echo $wdtv_pod; shows on the page: post_type: agenda_fietsroutes. And the line in the ‘else’ statement gets displayed.
Somewhere in the forumposts I came across the suggestion to add ?pods_debug_sql=1 to the page url. This throws out the following:

Fatal error: Uncaught ArgumentCountError: Too few arguments to function PodsData::get_sql(), 0 passed in C:\xampp\htdocs\door(en)trappers\wp-content\plugins\pods\classes\PodsData.php on line 718 and exactly 1 expected in C:\xampp\htdocs\door(en)trappers\wp-content\plugins\pods\classes\PodsData.php:3528 Stack trace: #0 C:\xampp\htdocs\door(en)trappers\wp-content\plugins\pods\classes\PodsData.php(718): PodsData->get_sql() #1 C:\xampp\htdocs\door(en)trappers\wp-content\plugins\pods\classes\Pods.php(2715): PodsData->select(Object(stdClass)) #2 C:\xampp\htdocs\door(en)trappers\wp-content\plugins\pods\classes\Pods.php(389): Pods->find(Object(stdClass)) #3 C:\xampp\htdocs\door(en)trappers\wp-content\plugins\pods\includes\classes.php(22): Pods->__construct('agenda_fietsrou...', Array) #4 C:\xampp\htdocs\door(en)trappers\wp-content\themes\hestia-child\wdtv\templateparts\wdtv_upcoming_programm.php(22): pods('agenda_fietsrou...', Array) #5 C:\xampp\htdocs\door(en)trappers\wp-includes\template.php(732): require('C:\\xampp\\htdocs...' in C:\xampp\htdocs\door(en)trappers\wp-content\plugins\pods\classes\PodsData.php on line 3528

Hope this makes any sense to you. But I think it is a problem that the line $wdtv_pod = pods( 'agenda_fietsroutes', get_the_id() ); doesn’t seem to return the id. And is this the cause for the fatal error?

Hope to hear from you,
Bert.

Hi @jory,

After some more trial and error, I managed to get the id of the post(s) using the following line of code after

if ( $wdtv_pods->total() > 0 ) {
  while ( $wdtv_pods->fetch() ) { 

$wdtv_pod_id = $wdtv_pods->display( 'id');

I’m still in the loop that gets the info from the agenda_fietsroutes pod. Might this be a problem? Is it possisble to nest a pods-loop within a pods-loop (an nested loop)?

I hope to get a reaction from you. Meanwhile I’ll keep trying to get this to work.
Thank you so far,
Bert.

The display method should never be used to get the ID.

Always make sure you use the correct function for the current purpose.
Since you don’t be using the ID on the actual page a method named display already indicates it’s not meant for what you want to do.

You can just use $wdtv_pods->id().

Is it possisble to nest a pods-loop within a pods-loop (an nested loop)?

Please look at the field() method in the code or documentation for fetching relationships (https://pods.io/docs/code/pods/field/).
This method will (by default) return an array of relationships.
You can then loop through this array.

I would advice you to learn more about PHP and how functions, loops, objects etc. work.

Cheers, Jory

Hi @jory,

I changed that line of code. I’m trying to get things working using the pods tutorial “get values from a relationship field”, but when I use the line: $wdtv_related = $wdtv_pod->field( 'title' ); I get a Fatal error: Uncaught Error: Call to a member function field() on int in C:\xampp\htdocs\door(en)trappers\wp-content\themes\hestia-child\wdtv\templateparts\wdtv_upcoming_programm.php:38 Stack trace: #0 C:\xampp\htdocs\door(en)trappers\wp-includes\template.php(732): require() #1 C:\xampp\htdocs\door(en)trappers\wp-includes\template.php(676): load_template('C:\\xampp\\htdocs...', false, Array) #2 C:\xampp\htdocs\door(en)trappers\wp-includes\general-template.php(204): locate_template(Array, true, false, Array) #3 C:\xampp\htdocs\door(en)trappers\wp-content\themes\hestia-child\wdtv_shortcodes.php(15): get_template_part('/wdtv/templatep...') #4 C:\xampp\htdocs\door(en)trappers\wp-includes\shortcodes.php(343): wdtv_programm_upcoming('', '', 'wdtv_programm_u...') #5 [internal function]: do_shortcode_tag(Array) #6 C:\xampp\htdocs\door(en)trappers\wp-includes\shortcodes.php(218): preg_replace_callback('/\\[(\\[?)(wdtv_p...', 'do_shortcode_ta...', '\n<div class="wp...') #7 C:\xampp\htdocs\door(en)trappers\wp-includes\class-wp-hook. in C:\xampp\htdocs\door(en)trappers\wp-content\themes\hestia-child\wdtv\templateparts\wdtv_upcoming_programm.php on line 38

Line 38 is the line that starts with $wdtv_related =
I’ve tried some of the available options as mentioned on the field() documentation page, but it keeps throwing that error. I did a copy and paste of that line of code to be sure there wasn’t a typo in it, but no change of result.

Bert.

That is only logical because of this line:

$wdtv_pod = $wdtv_pods->id();
You overwrite the Pods object with the ID of that object.
You can just remove that line.

Hi @jory,

Thank you so much for your answers and patience! I finally got this working. My – working – template now looks like this:

<?php
/*
  Template Name:      wdtv upcoming programm
  Template Post Type: post, page, fietsroutes, agenda_fietsroutes
  Description:        Template om de komende fietsroutes van het programma
                      weer te geven op de homepages.
*/
?>
<div class="wdtv_club_titel">Programma aankomende weken:</div>
<?php
//  Get the weeknumber for the current week and the next week
$cur_week_nr = date('W');
$nxt_week_nr = ($cur_week_nr + 1);

//  Set up the parameters for pods::find
$params = array(
  'where' => 'week.meta_value = "' . $cur_week_nr . '" OR week.meta_value = "' . $nxt_week_nr . '"',
  'orderby' => 'datum.meta_value',
  'limit' => -1
);

//  Run the find
$wdtv_pods = pods( 'agenda_fietsroutes', $params );

if ( $wdtv_pods->total() > 0 ) {
  while ( $wdtv_pods->fetch() ) {
    $route          = $wdtv_pods->display( 'route' );
    $datum          = $wdtv_pods->display( 'datum' );
    $tijd_vertrek   = $wdtv_pods->display( 'vertrektijd' );
    $plaats_vertrek = $wdtv_pods->display( 'vertrekplaats' );
    ?>
    <div id="wdtv_programma_container">
    <?php
    //  Get additional info from related pod
    $wdtv_related = $wdtv_pods->field( 'route' );
    if ( !empty ( $wdtv_related ) ) {
         $wdtv_id = $wdtv_related[ 'ID' ];
         $wdtv_distance = get_post_meta( $wdtv_id, 'afstand', true );
    }
    else {
      echo " geen relaties gevonden";
    }
    ?>

        <div id="wdtv_programma_item">
          Op <?php echo $datum; ?> rijden we de <?php echo '<a href="' . esc_url( get_permalink( $wdtv_id ) ) . '">' . $route . '</a>'; ?><br>
          Lengte: <?php echo $wdtv_distance; ?> km.
        </div>
      </div><?php
  }
}
else {
  ?>er staan geen activiteiten gepland voor de komende weken.<?php
}
?>

As you can see, I even got some extra info from the related pod (distance).
I learned a lot from this and there is still a lot to learn! I’m gonna give pods a 5 star rating on wordpress. Is there a place where you can share your code for others with similar problems?

Thanks again,
Bert.

Hi @berttervoert

Good to hear you’ve solved it!
And indeed, I think you would greatly benefit from learning more about PHP and the WordPress codebase in general. There is a lot available online to learn from..
As for sharing the code. When we feel like a case should be mentioned in the documentation we will, though our documentation isn’t meant to cover general PHP knowledge.
Normally users look for similar issues in this forum first. That is why I keep replying in English ??
Other great resources are php.net, wordpress.stackexchange.com and GitHub.

Vriendelijke groeten ??
Jory
