Order inside a concatenated string

I think this is a simple problem, but I’m stuck.

I’ve got a flexible content block setup for page building, and I’ve run into an issue. One of the options is for the user to specify a heading level from a dropdown (heading 1 through heading 6). Which ever heading level is chosen, a string is output. When I get the data and concatenate the string to wrap some HTML around the data, the order is wrong.

Here’s the code:

while ( have_rows('page_layout') ) : the_row();
if( get_row_layout() == 'heading_text' ):
$headingLevel = the_sub_field('heading_level');
echo '<h' . $headingLevel . '>Another variable here with heading content</' . $headingLevel . '>';

The HTML output is as such:

Heading 1<h>Another variable here with heading content</>

The text ‘Heading 1’ should appear inside the HTML tags where I’ve used the variable, but it doesn’t.

I realise I’ll have to then explode the string to isolate the number after ‘heading ‘, but I’d like to solve this problem first.

you need to use get_sub_field rather than the_sub_field. The first returns the values the second echoes the value, I also added the missing ‘h’ to the closing tag

while ( have_rows('page_layout') ) : the_row();
  if( get_row_layout() == 'heading_text' ):
    $headingLevel = get_sub_field('heading_level');
    echo '<h' . 
      $headingLevel . 
      '>Another variable here with heading content</h' . 
      $headingLevel . '>';

Thank you, John. I knew it was something simple.. I don’t know how I missed it. Also, I isolated the heading number using the PHP explode function:

					<?php

						// check if the flexible content field has rows of data
						if( have_rows('page_layout') ):

						     // loop through the rows of data
						    while ( have_rows('page_layout') ) : the_row();

								
								
						        if( get_row_layout() == 'heading_text' ):
		        	
							        $headingLevel = get_sub_field('heading_level');
							    	$headingLevelIsolated = (explode(" ",$headingLevel));
							    	$headingContent = get_sub_field('heading_content');

						        	echo '<h' . $headingLevelIsolated[1] . '>' . $headingContent . '</h' . $headingLevelIsolated[1] . '>';
