# Exclude empty fields from emails

{% hint style="info" %}
Super Forms also has an option that does this for you on the form builder page under **Form Settings > Confirmation E-mail > Exclude empty values from email loop**
{% endhint %}

```php
add_filter( 'super_before_sending_email_data_filter', '_super_exclude_empty_field_from_email', 10, 2 );
function _super_exclude_empty_field_from_email( $data, $atts ) {

    // REPLACE 123 WITH YOUR FORM ID
    $id = 123;

    $form_id = absint($atts['post']['form_id']); // contains the form ID that was submitted

    if( $form_id == $id ) {
        foreach( $data as $k => $v ) {
            if( $v['type']=='files' ) {
                if( !isset($v['files']) ) {
                    // 1 = Exclude from confirmation email only
                    // 2 = Exclude from all emails
                    $data[$k]['exclude'] = 2;
                }
                continue;
            }

            // We exclude whenever the field value equals 0 or when the value was empty
            if( ($v['value']=='0') || ($v['value']=='') ) {
                // 1 = Exclude from confirmation email only
                // 2 = Exclude from all emails
                $data[$k]['exclude'] = 2;
            }
        }
    }
    return $data;
}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.super-forms.com/developers/code-examples/exclude-empty-fields-from-emails.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
