Form Data Array in Custom PDF Templates – Developers

Introduction​

Gravity Forms merge tags and conditional shortcodes are useful PDF-building tools, but there are drawbacks. For instance, you cannot create nested conditionals or do any post-processing to the entry data. As an example, you cannot determine the age of someone by their date of birth, or convert a field to upper case using the standard merge tags. To achieve this behaviour we need to utilise PHP and the $form_data associative array – a processed and escaped version of the $entry object specific to Gravity PDF.

Template Tutorial – Part 3​

An example of the Hello World Gravity PDF PHP template

First, we're going to convert the template we did in the Part 2 exercise from merge tags/conditional shortcodes to PHP. Then we'll look at the two post-processing use-cases we discussed in the introduction. Finally, we'll take a closer look at the $form_data array.

Convert Merge tags to PHP​

Our Hello World template included merge tags for field #1 and field #3 – our name and select field, respectively. Their equivalent access keys in the $form_data array are $form_data['field'][1]['first'] and form_data['field'][3]. So we'll update the PDF template to:

<p>You're from <?php echo esc_html( $form_data['field'][3] ); ?>, <?php echo esc_html( $form_data['field'][1]['first'] ); ?>? How cool is that!</p>
note

The $form_data array is grouped into a number of different sub-arrays, but the most common is $form_data['field']. As the name suggests, it contains the field data for most Gravity Forms field – add-ons that add new fields may be stored in a separate sub-array.

To keep your code cleaner, you could set these values as variables earlier in the template and output the variable names in the template instead:

<?php
$location = $form_data['field'][3] ?? '';
$name     = $form_data['field'][1]['first'] ?? '';
?>

<p>You're from <?php echo esc_html( $location ); ?>, <?php echo esc_html( $name ); ?>? How cool is that!</p>

If you're accessing a lot of fields from $form_data['field'] you might like to assign it a shorter variable name:

<?php
   $f = $form_data['field'];
  
   $location = $f[3] ?? '';
   $name     = $f[1]['first'] ?? '';
?>

<p>You're from <?php echo esc_html( $location ); ?>, <?php echo esc_html( $name ); ?>? How cool is that!</p>

Convert Conditional Shortcode to PHP​

info

When doing conditionals with the $form_data array, if your string comparison contains any of the following characters <, >, ", ' or & you'll need to use the WordPress function esc_html() to get the desired result. Example: if ( $form_data['field'][5] === esc_html( 'Honey & Spice' ) ):'

The conditional shortcodes we used in our Hello World template are basic IF x = y THEN logic. Now we have access to the location field in PHP it's trivial to replace in PHP:

<?php if ( $location === 'Earth' ): ?>
    <p>The birth-rate on Earth has dropped almost 25% in the past 50 years due to colonisation of the solar system.</p>
<?php endif; ?>

<?php if ( $location === 'Moon' ): ?>
    <p>The lunar colony was first established in 2115 with a population of 200. Now it supports over 900,000 people.</p>
<?php endif; ?>

<?php if ( $location === 'Mars' ): ?>
    <p>Mars was the second body to be colonised in the solar system in 2135, 20 years after the moon.</p>
<?php endif; ?>

<?php if ( $location === 'Titan' ): ?>
    <p>Titan's colony is only recently established. You're one of only 500 people currently living there!</p>
<?php endif; ?>

You could have also used a switch statement to get the same result:

switch ( $location ) {
    case 'Earth':
        echo '<p>The birth-rate on Earth has dropped almost 25% in the past 50 years due to colonisation of the solar system.</p>';
    break;

    case 'Moon':
        echo '<p>The lunar colony was first established in 2115 with a population of 200. Now it supports over 900,000 people.</p>';
    break;

    case 'Mars':
        echo '<p>Mars was the second body to be colonised in the solar system in 2135, 20 years after the moon.</p>';
    break;

    case 'Titan':
        echo "<p>Titan's colony is only recently established. You're one of only 500 people currently living there!</p>";
    break;
}

And IF/ELSE conditions are simple too:

<?php if ( $location === 'Earth'  ): ?>
    <p>The birth-rate on Earth has dropped almost 25% in the past 50 years due to colonisation of the solar system.</p>
<?php else: ?>
    <p>Planning a vacation? Earth has thousands of beautiful destinations.</p>
<?php endif; ?>

Doing More With PHP​

With the full power of PHP at your fingertips post-processing Gravity Forms data becomes easy. Case in point, it's relatively simple to determine the age of someone using their date of birth.

Let's go back to the Hello World sample form and add a date field. For simplicity’s sake, name it Date of Birth and change the Date Format to dd-mm-yyyy then save your form. Finally, submit a new entry and enter a date of birth.

Now let's add our PHP logic to display the age in your PDF template:

<?php
$dob            = $form_data['field'][4]; /* change the ID if your date field has something different */
$dob_iso_format = date( 'Y-m-d', strtotime( $dob ) );
$dob_datetime   = new DateTime( $dob_iso_format );
$age            = $dob_datetime->diff( new DateTime( 'today' ) )->y;
?>

<p>Congratulations! You're <?php echo esc_html( $age ); ?> years old.</p>

Another example is converting case. It's simple to convert entry data to upper case, lower case or sentence case. Just run the field through a PHP function like mb_strtoupper() or strtoupper() (we recommend using the multibyte PHP functions where possible).

<?php
$location = mb_strtoupper( $form_data['field'][3], 'UTF-8' ); /* strtoupper( $form_data['field'][3] ) is also suitable */
?>

<?php echo esc_html( $location ); ?>

PDF templates are just PHP files that are loaded in WordPress. Anything you can do in WordPress you can do in the PDF templates. For instance, you can output entire posts in a PDF:

<?php
echo esc_html( get_the_title( 120 ) ); /* display post #120's title */
echo wp_kses_post( get_the_content( 120 ) ); /* display post #120's content */
?>

Form Data Array Up Close​

The $form_data array is used to access the Gravity Forms entry information, but, unlike merge tags, there's no selector to show you what's actually in the array. That's why we've added a data URL parameter which shows you the complete contents of the $form_data array.

To see the array, first view a PDF in your admin area. When it loads add ?data=1 to the URL and reload. The address should look similar to this:

https://gravitypdf.com/pdf/12i410491024123/100/?data=1
caution

From Gravity PDF 6.4+ this helper parameter is only available when Debug Mode is enabled or the WordPress environment isn't set to production (WP_ENVIRONMENT_TYPE !== 'production').

If we take a look at the $form_data array from the tutorial above you'll see a simple structured associative array:

Array
(
    [form_id] => 22
    [entry_id] => 134
    [form_title] => Hello World
    [form_description] => Gravity PDF tutorial form used in our development documentation.

        (
            [1.Name] => Array
                (
                    [prefix] =>
                    [first] => Jake
                    [middle] =>
                    [last] => Jackson
                    [suffix] =>
                )

            [1] => Array
                (
                    [prefix] =>
                    [first] => Jake
                    [middle] =>
                    [last] => Jackson
                    [suffix] =>
                )

            [Name] => Array
                (
                    [prefix] =>
                    [first] => Jake
                    [middle] =>
                    [last] => Jackson
                    [suffix] =>
                )

            [3.Where do you live?] => Mars
            [3] => Mars
            [Where do you live?] => Mars
            [3.Where do you live?_name] => Mars
            [3_name] => Mars
            [Where do you live?_name] => Mars
        )
)

As we mentioned earlier, our main sub-key is $form_data['field'], but there are other important details like the submission date $form_data['date_created'] and the entry owner's user ID $form_data['misc']['created_by']. Each Gravity Forms is unique and will create a different $form_data array. Gravity Forms Add-Ons like Survey and Signature also add their own unique sub-keys in the array.

You will also notice in our $form_data['field'] array there are three different references (array keys) for the same field. The keys without any ID are present for legacy reasons, while keys with the ID-and-field-combination make it easier to distinguish what field you are trying to reference. With that said, we recommend accessing the field data using the ID in your templates.

Accessing Common Field Data​

The $form_data variable is an associative array, so more experienced PHP developers should have no problem accessing the information they need. However, large forms can make this array intimidating for first time template builders. Below are examples of how to access the most common Gravity Forms fields.

Standard Fields​

Single Line Text​

/* 20 is the ID of our field */
echo esc_html( $form_data['field'][20] );

Paragraph Text​

/* 35 is the ID of our field */
echo esc_html( $form_data['field'][35] );
/* 3 is the ID of our field */
echo esc_html( $form_data['field'][3] ); /* for selected Drop Down value */
echo esc_html( $form_data['field']['3_name'] ); /* for selected Drop Down name */

Multiselect​

/* Output all selected items by value. 5 is the ID of our field */
if ( is_array( $form_data['field'][5] ) ) {
    echo wp_kses_post( implode( '<br>', $form_data['field'][5] ) ); /* output value of each selected item */
}

/* Output all selected items by label */
if ( is_array( $form_data['field']['5_name'] ) ) {
    echo wp_kses_post( implode( '<br>', $form_data['field']['5_name'] ) ); /* output name of each selected item */
}

/* Check if there is a multiselect option selected */
if ( in_array( 'Apple', (array) $form_data['field'][43], true ) ) {
   // Do something when the specific option is selected
}

/* Check if there are multiple multiselect options selected */
foreach( (array) $form_data['field'][43] as $item ) {
    switch( $item ) {
      case 'Apple':
          // Do something when the specific option is selected
      break;
     
      case 'Orange':
          // Do something when the specific option is selected
      break;
    }
}

/* Output in a list */
if ( is_array( $form_data['field'][5] ) ) {
    echo '<ul>';

    foreach( $form_data['field'][5] as $item ) {
        echo '<li>' . wp_kses_post( $item ) . '</li>';
    }

    echo '</ul>';
}

Number​

/* 25 is the ID of our field */
echo esc_html( $form_data['field'][25] );

Checkbox​

/* Output all selected items by value. 43 is the ID of our field */
if ( is_array( $form_data['field'][43] ) ) {
    echo wp_kses_post( implode( '<br>', $form_data['field'][43] ) ); /* output value of each selected item */
}

/* Output all selected items by label */
if ( is_array( $form_data['field']['43_name'] ) ) {
    echo wp_kses_post( implode( '<br>', $form_data['field']['43_name'] ) ); /* output name of each selected item */
}

/* Check if there is a checkbox option selected */
if ( in_array( 'Apple', (array) $form_data['field'][43], true ) ) {
   // Do something when the specific checkbox is enabled
}

/* Check if there are multiple checkbox options selected */
foreach( (array) $form_data['field'][43] as $item ) {
    switch( $item ) {
      case 'Apple':
          // Do something when the specific checkbox is enabled
      break;
     
      case 'Orange':
          // Do something when the specific checkbox is enabled
      break;
    }
}

/* Output in a list */
if ( is_array( $form_data['field'][43] ) ) {
    echo '<ul>';

    foreach ( $form_data['field'][43] as $item ) {

    }

    echo '</ul>';
}

Chained Selects​

You'll need the Chained Selects add-on to use this field type.

/*
 * 3 is the ID of our field
 */

echo esc_html( implode( ', ', $form_data['field'][3] ) );

Slim Image Cropper​

note

The Slim Image Cropper for Gravity Forms add-on has been discontinued and Image Hopper is the recommended replacement.

You'll need the Slim Image Cropper for Gravity Forms add-on to use this field type.

/*
* 3 is the ID of our field
*/
echo esc_html( $form_data['field'][3]['url'] ); /* The URL of the uploaded image */

$path = isset( $form_data['field'][3]['path'] ) ? $form_data['field'][3]['path'] : ''; /* The path to the uploaded image (if we can locate it) */
if ( is_file( $path ) ) {
   echo '<img src="' . esc_attr( $path ) . '" width="200" />';
}

Image Hopper​

You'll need the Image Hopper add-on to use this field type.

/* Add images to PDF for Image Hopper field ID 27 */
if ( is_array( $form_data['field']['27_path'] ) ) {
    foreach ( $form_data['field']['27_path'] as $path ) {     
       /* verify path has an image extension and it exists on the server */
       if ( is_file( $path ) ) {
            echo '<img src="' . esc_attr( $path ) . '" width="200" />';
       }
    }
}

/* Add images to PDF with secure link for Image Hopper field ID 27 */
if ( is_array( $form_data['field']['27_path'] ) ) {
    foreach ( $form_data['field']['27_path'] as $key => $path ) {     
       /* verify path has an image extension and it exists on the server */
       if ( is_file( $path ) ) {
            echo '<a href="' . esc_url( $form_data['field']['27_secured'][ $key ] ) . '"><img src="' . esc_attr( $path ) . '" width="200" /></a>';
       }
    }
}

/* Output first image uploaded, if it exists */
if ( isset( $form_data['field']['27_path'][0] ) && is_file( $form_data['field']['27_path'][0] ) ) {
    echo '<img src="' . esc_attr( $form_data['field']['27_path'][0] ) . '" width="200" />';
}

Nested Forms​

You'll need the Gravity Perk Nested Forms add-on to use this field type.

/*
* 3 is the ID of our field in the Parent Form
*/
$nested_ids = explode( ',', $form_data['field'][3] );

Repeater​

The Repeater field contains an array of your field data, using the same structure as would be found in the $form_data['field'] array key.

For a simple single-level repeater:

<!-- The ID of our repeater field is 3 -->
<?php foreach ( $form_data['repeater'][3] as $data ): ?>
    <div class="users">
        <!-- The sub-field IDs will be unique to your repeater field -->
        <p>Name: <?php echo esc_html( $data[1]['first'] ); ?> <?php echo esc_html( $data[1]['last'] ); ?></p>
        <p>Email: <?php echo esc_html( $data[2] ); ?></p>
    </div>
<?php endforeach; ?>

For a multi-level repeater (in this case, three levels):

<!-- The ID of our repeater field is 3 -->
<?php foreach ( $form_data['repeater'][3] as $data ): ?>
    <div class="users">
        <!-- The sub-field IDs will be unique to your repeater field -->
        <p>Name: <?php echo esc_html( $data[1]['first'] ); ?> <?php echo esc_html( $data[1]['last'] ); ?></p>
        <p>Email: <?php echo esc_html( $data[2] ); ?></p>

        <?php foreach ( $data[3] as $jobs ): ?>
            <div style="border: 1px solid #000; margin-bottom: 10px">
                <p>Expertise: <?php echo esc_html( $jobs[4] ); ?></p>
                <p>Years: <?php echo esc_html( $jobs[5] ); ?></p>

                <ul class="urls">
                    <?php foreach ( $jobs[6] as $urls ): ?>
                        <li><?php echo esc_html( $urls[7] ); ?>/li>
                    <?php endforeach; ?>
                </ul>
            </div>
        <?php endforeach; ?>
    </div>
<?php endforeach; ?>
