Get field from post_object in Flexible Content

Hi,

I’ve got the Flexible Content add-on working for basic fields and that works fine.

Now I’ve got some CPT that I’d like to insert with the Post Object field. I had it working outside the Flexible Content but I can’t get it to work inside it.

When I link, for example, two posts, I get two div’s with a class’charts’. But they’re empty. No content, no fields from these posts. There’s something wrong with the way I call the fields I guess. I’ve got no clue how to figure it out.

My page: http://www.mediadigest.be/reclameinvesteringen/test-met-nieuwe-content-editor/

<?php while(has_sub_field("omd_content")) : // FLEXIBLE CONTENT ?>

<?php if ( get_row_layout() == "text" ) : ?>
<div class="main"><?php the_sub_field("text"); ?></div>

<?php elseif ( get_row_layout() == "table" ) : ?>
<div class="omdtable">
<h3><?php the_sub_field('table_title') ?></h3>
<div class="table-responsive">
<?php the_sub_field('table') ?>
</div>	
</div> 
<?php // everything works fine up to here ?>

<?php elseif ( get_row_layout() == "chart_picker" ) : ?>	

										<div class="charts">
											<?php if ( get_sub_field("chart") ) : ?>
											<?php foreach ( get_sub_field("chart") as $p ) : ?>
<?php echo get_permalink($p->ID); ?>
												<?php if( get_field( 'highcharts_beschrijving_van_de_grafiek', $p->ID) ): ?>
												<div class="description"><?php the_field('highcharts_beschrijving_van_de_grafiek', $p->ID) ?></div>
												<?php endif; ?>

										<div class="highchart chart-<?php echo $p->ID; ?> <?php the_field('highcharts_hoogte_grafiek', $p->ID) ?>">

a lot of html goes here... 

</div>

<?php endforeach; ?>
<?php endif; ?>	

										</div><!-- end .charts -->
			
<?php endif; ?>
<?php endwhile; ?>

Hi @Exelmans Graphics

I think your issue lies within these lines of code:

<?php if ( get_sub_field("chart") ) : ?>
											<?php foreach ( get_sub_field("chart") as $p ) : ?>
<?php echo get_permalink($p->ID); ?>
												<?php if( get_field( 'highcharts_beschrijving_van_de_grafiek', $p->ID) ): ?>
												<div class="description"><?php the_field('highcharts_beschrijving_van_de_grafiek', $p->ID) ?></div>
												<?php endif; ?>

The first line is OK (testing to see if your ‘chart’ custom field exists) but the line after is a foreach which makes no sense in this context as the post object in your chart field is a single value.

If you want to get the data associated with another post using the post object field simply do something like the following:

<?php if ( get_sub_field("chart") ) : 

	$p = get_sub_field("chart");
	// Variable now stores the post object for the post chosen by the user
	
	//You can now do stuff with that post e.g.
	$my_other_post = get_field( 'highcharts_beschrijving_van_de_grafiek', $p->ID);
	
	//This is example only - I have no idea what this field is or does
	if($my_other_post){
		echo $my_other_post;
	}

endif;// End check for chart field
?>

Thanks, that makes sense!
