Shortcode attributes to set options

Is it possible to pass shortcode attributes to acf_form($options)? It seems like I’m running into a race condition. For example using the shortcode [form_generator submit="Make a Request"], I get different results depending on which function I var_dump from. Ideally the submit attribute would get passed to the $options array and then to acf_form().

What I’m trying is something like this…

Using v4

// request-form.php - my plugin
function output_acf_form($submit) {
	// find the location of the plugin.
	$acf_base = plugin_basename('/advanced-custom-fields/acf.php');
	var_dump($submit);
	// check to see if acf is active.
	if (is_plugin_active($acf_base)) {

		// make sure that acf has access to the site before doing anything else.
		acf_form_head();

		// start organizing the form.
		$fields = get_field_objects();
		$fieldGroup;

		// make sure that the $key has a value and save it.
		foreach ($fields as $key => $field) {
			if ($key) {
				$fieldGroup = $field['field_group'];
			}
		}

		// store the options for the form.
		$options = array(
			'post_id' => 'new_post',
			'field_groups' => array($fieldGroup),
			'submit_value' => $submit,
			'return' => home_url('thank-you'),
			// 'updated_message' => 'I tried to redirect'
		);
	
		// prepare to return the content of the form.
		$content = acf_form($options);

		return $content;
	} else {
		echo "Something broke";
	}
}

function output_acf_form_shortcode($atts, $content = null) {
	
	$opts = shortcode_atts(array(
        // other options may get passed in here...
		'submit' => ''
	), $atts);
	$submit = $opts['submit'];
	
	$content = output_acf_form($submit);

	return $content;
}
add_shortcode('form_generator', 'output_acf_form_shortcode');

The only problem I can see with what you’re trying to do is that acf_form_head() must be called before any output is generated for the site. This function must be called before get_header() is called. When you call this function from a shortcode then this function is being called too late. Other than that, I don’t see anything in the code that you provided that might cause a problem.

@john

Thanks for the help. I was able to get around having to hardcode acf_form_head() into my theme by doing this (more or less) in the plugin.

function output_acf_form($args) {
  global $post;
  if (has_shortcode($post->post_content, 'my_shortcode')) {
    acf_form_head();
  }
// everything else...
}
