<form method="POST" action="<?php echo esc_url( admin_url('admin-post.php') ); ?>" enctype="multipart/form-data">
    <div class="form-group">
        <label>Invoices</label><br>
        <input type="file" class="form-input" name="invoice[]" multiple="">
        <small>Press Ctrl key to select multiple</small>
    </div>
    <div class="form-group">
        <input type="submit" name="submit" id="submit" class="form-submit" value="Add New Item" />
    </div>
</form>

I want to add images in to a new row in a repeater field.

I am assuming you got this worked out due to your later question.

Yes, i do that thing like this. But here only one repeated field pass to this function, is there any way to pass multiple fields and its values like an array. It’s a combination of image and input fields or textarea.

function insert_repeater_row_attachment($files,$post_id,$mainrepeater,$repeaterfield)
{
    require_once(ABSPATH . "wp-admin" . '/includes/image.php');
    require_once(ABSPATH . "wp-admin" . '/includes/file.php');
    require_once(ABSPATH . "wp-admin" . '/includes/media.php');
    $count = 0;
    $galleryImages = array();
    foreach ($files['name'] as $count => $value)
    {
        if ($files['name'][$count])
        {
            $file = array(
                'name'     => $files['name'][$count],
                'type'     => $files['type'][$count],
                'tmp_name' => $files['tmp_name'][$count],
                'error'    => $files['error'][$count],
                'size'     => $files['size'][$count]
            );
            $upload_overrides = array( 'test_form' => false );
            $upload = wp_handle_upload($file, $upload_overrides);
            $filename = $upload['file'];
            $parent_post_id = $post_id;
            $filetype = wp_check_filetype( basename( $filename ), null );
            $wp_upload_dir = wp_upload_dir();
            $attachment = array(
                'guid'           => $wp_upload_dir['url'] . '/' . basename( $filename ), 
                'post_mime_type' => $filetype['type'],
                'post_title'     => preg_replace( '/\.[^.]+$/', '', basename( $filename ) ),
                'post_content'   => '',
                'post_status'    => 'inherit'
            );
            $attach_id = wp_insert_attachment( $attachment, $filename, $parent_post_id );
            $attach_data = wp_generate_attachment_metadata( $attach_id, $filename );
            wp_update_attachment_metadata( $attach_id, $attach_data );
        }
        // Repeater child field name - "file"
        $file_row = array( $repeaterfield => $attach_id );
        // Repeater parent field name - "attachments"
        add_row($mainrepeater, $file_row, $post_id);
    }
}
