Hi guys,

I am trying to build simple system that lets assign pdfs to a page and then display choosen group of these pdf files in the widget.

Widget displays files from certain year, based on provided year in the widget field.

The problem I have is that it almost works. For some reason first file is being ommited. Can you please check my code and see what’s wrong ?

<ul id="pobieranieBoxWrapp">
	<?php if(get_field('rok_element_pobieranie', 'widget_' . $args['widget_id'])): 
		// Display and set year to a constant.
		$yearSet = get_field('rok_element_pobieranie', 'widget_' . $args['widget_id']) ?>
		<h4>
			<?php echo $yearSet; ?><span> årgang</span>
		</h4>
	<?php endif; ?>
	
	<?php 
	// We set page with pdfs
	if(get_field('skad_pobrac_pliki', 'widget_' . $args['widget_id'])): ?>
		<?php $stronaPdfy = get_field('skad_pobrac_pliki', 'widget_' . $args['widget_id']); ?>
	<?php endif; ?>
	
	<?php
	// check if the repeater field has rows of data
	if( have_rows('newsletter_year_section', $stronaPdfy)): ?>
		
		<?php 
		// Loop all files from the page
		while ( have_rows('newsletter_year_section', $stronaPdfy)) : the_row(); 
			// Condition to limit listed files only to selected year
			if (get_sub_field('newsletter_year') == $yearSet):
			?>
				<?php if( have_rows('newsletter_files_section', $stronaPdfy) ): the_row(); ?>
					<?php while( have_rows('newsletter_files_section', $stronaPdfy) ): the_row(); ?>
						<?php if(get_sub_field('newsletter_pdf_file')):
							//Set the pdf file
							$file = get_sub_field('newsletter_pdf_file'); 
							$fileTitle = $file['title'];
							$fileUrl = $file['url'];
							 ?>
							<li>
								<a target="_blank" rel="nofollow" href="<?php echo $fileUrl; ?>">
									<?php echo $shortName = str_replace('_',' ', $fileTitle); ?>
								</a>
							</li>
						<?php endif; ?>
					<?php endwhile; ?>
				<?php else : ?>
					<?php // empty ?>
				<?php endif; ?>
			<?php endif; ?>
		<?php endwhile; ?>
	<?php else : ?>
		<li>No files yet</li>
	<?php endif; ?>
</ul>

Hi @mastafu

Could you please make sure that the field returns the data correctly? Could you please debug it like this:

echo <pre>;
var_dump( get_field('newsletter_files_section', $stronaPdfy) );
echo </pre>;

Also, could you please share the JSON or XML export file of your field group so I can test it out on my installation?

Thanks 🙂

Returns Null, weird.
Will send you all files via email.

Looks like the problem lies in this.

This:
<?php if( have_rows('newsletter_files_section', $stronaPdfy) ): the_row(); ?>

    <?php while( have_rows('newsletter_files_section', $stronaPdfy) ): the_row(); ?>

Should be like this:

<?php if( have_rows('newsletter_files_section') ): ?>

    <?php while( have_rows('newsletter_files_section') ): the_row(); ?>
