Using a Shortcode within a Shortcode - wordpress

Question

A client is using WPBakery and a form is being pulled into the description attribute of a shortcode. Ordinarily you would pull the form by its shortcode but the boiler plate demo has the form being pulled with a string beginning with a hashtag.
E-8_JTVCbWM0d3BfZm9ybSUyMGlkJTNEJTIyNDc0JTIyJTVE
[trx_sc_title title_style="accent" title_align="left" link_style="default" title="Stay Tuned for Our Updates" subtitle="newsletter signup" description="#E-8_JTVCbWM0d3BfZm9ybSUyMGlkJTNEJTIyNDc0JTIyJTVE"]
is equivalent to:
[trx_sc_title title_style="accent" title_align="left" link_style="default" title="Stay Tuned for Our Updates" subtitle="newsletter signup" description="[mc4wp_form id="474"]"]
I need to pull a different form from ninjaforms( [ninja_form id=3] ) instead of the mailchimp form in the example. How do I convert the shortcode in the same manner they did?
Thanks in advance for any insight as to what is going on here.

Answer 1

use two shortcodes. so that it won't be complicated.
function kp_shortcode1($atts, $content = null)
{
ob_start();
?>
<div class="sc1-section">
<?php echo do_shortcode($content); ?>
</div>
<?php
$output = ob_get_clean();
return $output;
}
add_shortcode('kp_shortcode1', 'kp_shortcode1');
function kp_shortcode2($atts, $content = null)
{
ob_start();
?>
<div class="sc2-section">
<h1>shortcode 2 content</h1>
</div>
<?php
$output = ob_get_clean();
return $output;
}
add_shortcode('kp_shortcode2', 'kp_shortcode2');
Inside the wordpress backend use
[kp_shortcode1]
[kp_shortcode2]
[kp_shortcode2]
[kp_shortcode2]
[/kp_shortcode1]
Output would be :
<div class="sc1-section">
<div class="sc2-section">
<h1>shortcode 2 content</h1>
</div>
<div class="sc2-section">
<h1>shortcode 2 content</h1>
</div>
<div class="sc2-section">
<h1>shortcode 2 content</h1>
</div>
</div>
