I have built a repeater field to collect two text inputs, two dates and a number, but the fields are not in the entries, nor are they in the email submission, any help would be appreciated.

add_filter('gform_form_post_get_meta_1', 'add_my_field');
function add_my_field($form)
{

    // Create a Single Line text field for the projects name
    $projectName = GF_Fields::create(array(
        'type'   => 'text',
        'id'     => 500, // The Field ID must be unique on the form
        'formId' => $form['1'],
        'label'  => 'Project Name',
        'pageNumber'  => 1, // Ensure this is correct
    ));

    // Create a Single Line text field for the projects name
    $client = GF_Fields::create(array(
        'type'   => 'text',
        'id'     => 501, // The Field ID must be unique on the form
        'formId' => $form['1'],
        'label'  => 'Client',
        'pageNumber'  => 1, // Ensure this is correct
    ));

    // Create a Start Date field for the projects name
    $dateStart = GF_Fields::create(array(
        'type'   => 'date',
        'id'     => 502, // The Field ID must be unique on the form
        'formId' => $form['1'],
        'label'  => 'Contract Start Date',
        'placeholder' => '(DD/MM/YYYY)',
        'pageNumber'  => 1, // Ensure this is correct
    ));

    // Create an End Date field for the projects name
    $dateEnd = GF_Fields::create(array(
        'type'   => 'date',
        'id'     => 503, // The Field ID must be unique on the form
        'formId' => $form['1'],
        'label'  => 'Contract End Date',
        'placeholder' => '(DD/MM/YYYY)',
        'pageNumber'  => 1, // Ensure this is correct
    ));

    // Create a Single Line number field for the projects name
    $subContractCost = GF_Fields::create(array(
        'type'   => 'number',
        'numberFormat' =>    'currency',
        'id'     => 504, // The Field ID must be unique on the form
        'formId' => $form['1'],
        'label'  => 'Subcontract Cost (£)',
        'pageNumber'  => 1, // Ensure this is correct
    ));


    // Create a repeater projects.
    $projects = GF_Fields::create(array(
        'label' => 'Extra Projects',
        'type'             => 'repeater',
        'id'               => 505, // The Field ID must be unique on the form
        'formId'           => $form['1'],
        'addButtonText'    => '+ Add Project', // Optional
        'removeButtonText' => '- Remove Project', // Optional
        'maxItems'         => 3, // Optional
        'pageNumber'       => 1, // Ensure this is correct
        'fields'           => array($projectName, $client, $dateStart, $dateEnd, $subContractCost), // Add the fields here.
    ));

    $form['fields'][] = $projects;
    array_splice($form['fields'], 60, 0, array($projects));

    return $form;
}

// Remove the field before the form is saved. Adjust your form ID
add_filter('gform_form_update_meta_1', 'remove_my_field', 10, 3);
function remove_my_field($form_meta, $form_id, $meta_name)
{

    if ($meta_name == 'display_meta') {
        // Remove the Repeater field: ID 505
        $form_meta['fields'] = wp_list_filter($form_meta['fields'], array('id' => 505), 'NOT');
    }

    return $form_meta;
}

// Hide progress bar on first form page
add_filter('gform_progress_bar', 'hide_progress_bar_wrap', 10, 3);
