Introduction

The following tutorial shows you how to convert PDF forms to HTML using a hosted FormVu cloud API, such as:

Whilst all the above services can be accessed with plain old HTTP requests, this tutorial uses our open source PHP IDRCloudClient which provides a simple PHP wrapper around the REST API.

Prerequisites

Using composer, install the idrsolutions-php-client package with the following command:

composer require idrsolutions/idrsolutions-php-client

Code Example

Here is a basic code example to convert PDF forms to HTML. Configuration options and advanced features can be found below.

<?php

require_once __DIR__ . "/PATH/TO/vendor/autoload.php";

use IDRsolutions\IDRCloudClient;

$endpoint = "http://exampleURL.com/" . IDRCloudClient::INPUT_FORMVU;  
$parameters = array(
    //'token' => 'Token', // Required only when connecting to the IDRsolutions trial or cloud subscription servers
    'input' => IDRCloudClient::INPUT_UPLOAD,
    'file' => __DIR__ . 'path/to/file.pdf'
);

$results = IDRCloudClient::convert(array(
    'endpoint' => $endpoint,
    'parameters' => $parameters
));

IDRCloudClient::downloadOutput($results, __DIR__ . '/');

echo $results['downloadUrl'];

Configuration Options

The FormVu API accepts a stringified JSON object containing key value pair configuration options to customise your conversion. The settings should be added to the parameters array. A full list of the configuration options to convert PDF forms to HTML can be found here.

'settings' => '{"key":"value","key":"value"}'

Upload by URL

As well as uploading a local file you can also provide a URL which the FormVu Microservice will download and then perform the conversion. To do this you should replace the input and file values in the parameters array with the following.

'input' => IDRCloudClient.DOWNLOAD
'url' => 'http://exampleURL/exampleFile.pdf'

Using Authentication

If you have deployed your own FormVu Microservice that requires a username and password to convert PDF forms to HTML, you will need to provide them with each conversion. These are provided by adding two variables named username and password to the parameters array as shown below.

'username' => 'Username_If_Required',
'password' => 'Password_If_Required',

If this is the case you will also need to provide the authentication values to the downloadOutput method as well.

IDRCloudClient::downloadOutput($results, __DIR__ . '/','newFileName','username','password');
