how to insert php var in code

Question

I have got this working code using wordpress and advanced custom fields:

$include = get_pages('include=1575');
$title = apply_filters('the_title',$include[0]->post_title);
$content = apply_filters('the_content',$include[0]->post_content);

I want to create a var replacing the post_id in include=1575. I get this var using:

$site_id = the_field('id_grundgedanke'); // output exp: 1575

How I can I combine these? I have tried the following:

 $site_id = the_field('id_grundgedanke');
 $include = get_pages('include=' . $site_id);
 $title = apply_filters('the_title',$include[0]->post_title);
 $content = apply_filters('the_content',$include[0]->post_content);

Which does not work.

Use get_field() instead of the_field().

get_field() - Returns the value of the specified field.

the_field() - Displays the value of the specified field. This function is the same as echo get_field($field_name);

Corrected code:

 $site_id = get_field('id_grundgedanke'); // use get_field
 $include = get_pages("include=" . $site_id);
 $title = apply_filters('the_title',$include[0]->post_title);
 $content = apply_filters('the_content',$include[0]->post_content);

there is one mistake, "include=$site_id" does not work. I have suggested the necessary edit!

@MarianRick: You should print $include and check what data you are receiving. Write echo '<pre>'; print_r($include);
