Hello

This time I’m using repeater fied to create a faq.

Each repeater correspond to a category; I have inside an “question row” and “answer row” field.

It’s working well on my FAQ page.

So now I wish random it on each page: PAge category A -> random FAQ category A and create an infitite loop navigation “next” and “previous” question in the same repeater.

For the random I have a warning “shuffle() expects parameter 1 to be array, null given”. How to fix it ?

And I don’t know how create my nav infinite loop for the next and previous button

This is my code:

<div id="infobulle">
	<div class="inner">

		<div class="open-bulle">
		
			<img src="<?php echo $imageC['url'] ;?>" alt=" <?php echo bloginfo('name') ?>" />
			<h3>Advice</h3>
		
		</div>

		<?php 	
			$repeater = get_field( 'education_faq' );	
			shuffle( $repeater );
			$i=0; ?>
	
			<div class="quest-rep-bulle">
					
			<?php foreach($repeater as $row){?>
				
				<div class="titre">
					<h5><?php echo $row['question_faq_education']; ?></h5>
					<hr class="colomethode">
					</div>			
					<div class="txtCourant"> <?php echo $row['reponse_faq_education']; ?></div>

				<?php
				 if (++$i == 1) break;
			} ?>
				
			
			
			<div class="NavFAQ innerBtnCentre"><span class="icon-precedent">Previous</span><a href="" class="btnNoirSimple">FAQ</a><span class="icon-suivant">Next</span></div>
		</div>
	</div>
	
	
	

</div>
