Can't get values while creating loop for shortcode

So i’m trying to create small plugin for specific shortcode, but i’m not getting values from subfields, so probably i’m missing something.

The code:

function ssf(){
	global $post;
	$post_id = $post->id;
	$rep = get_field('sourcepage', $post_id);
	if ($rep && is_array($rep)) { 
		$linkbutton = the_sub_field('link_przycisku');
	    $textbutton = the_sub_field('nazwa_przycisku');
		foreach ($rep as $item) {
			$output .= '<span class="set blue">
				<a class="btn-pbt pri ico" href="'.$item['linkbutton'].'">'.$item['textbutton'].'</a>
			</span>';	
		}
	}
	return $output;
}
add_shortcode('guzik', 'ssf');

Basically it’s repeater with two subfields. The Output from shortcode should render button with custom link and custom name.

Output doesn’t render any values from fields(only span container), i would appreciate some help in that matter.

Hi @nikodemsky.

Thanks for reaching out to us.

You will need to change the_sub_field method to get_sub_field in order to output the value.

Let me know how it goes.

Already tested it before, but it’s the same.

You can look by yourself:

Proper button should look like this:

Fields are filled ofc:

Ok, i solved my problem. Seems like those two directives was not even required(i can use subfields as arrays).

The problem was with NAMES of those fields! I forgot _ symbol in between.

So the code at the end is:

function ssf(){
	global $post;
	$post_id = $post->id;
	$rep = get_field('sourcepage', $post_id);
	if ($rep && is_array($rep)) {
		foreach ($rep as $item) {
			$output .= '<span class="set blue">
				<a class="btn-pbt pri ico" href="'.$item['link_przycisku'].'">'.$item['nazwa_przycisku'].'</a>
			</span>';
		}
	}
	return $output;
}
add_shortcode('guzik', 'ssf');
