PHP API Client

This library offers the API client to communicate with mosparo to verify a submission.

---

Description

With this PHP library you can connect to a mosparo installation and verify the submitted data.

Installation

Install this library by using composer:

composer require mosparo/php-api-client

Usage

1. Create a project in your mosparo installation
2. Include the mosparo script in your form

<div id="mosparo-box"></div>

<script src="https://[URL]/build/mosparo-frontend.js" defer></script>
<script>
    var m;
    window.onload = function(){
        m = new mosparo('mosparo-box', 'https://[URL]', '[UUID]', '[PUBLIC_KEY]', {loadCssResource: true});
    };
</script>

3. Include the library in your project

composer require mosparo/php-api-client

4. After the form was submitted, verify the data before processing it

<?php
require_once(__DIR__ . '/vendor/autoload.php');

$client = new Mosparo\ApiClient\Client($url, $publicKey, $privateKey, [ /* Options for Guzzle */ ]);

$mosparoSubmitToken = $_POST['_mosparo_submitToken'];
$mosparoValidationToken = $_POST['_mosparo_validationToken'];

$result = $client->verifySubmission($_POST, $mosparoSubmitToken, $mosparoValidationToken);

if ($result->isSubmittable()) {
    // Send the email or process the data
} else {
    // Show error message
}

API Documentation

Client

Client initialization

Create a new client object to use the API client.

/**
 * @param string $url URL of the mosparo installation
 * @param string $publicKey Public key of the mosparo project
 * @param string $privateKey Private key of the mosparo project 
 * @param array $args Arguments for the Guzzle client, see https://docs.guzzlephp.org/en/stable/request-options.html
 */
$client = new Mosparo\ApiClient\Client($url, $publicKey, $privateKey, $args);

Verify form data

To verify the form data, call verifySubmission with the form data in an array and the submit and validation tokens, which mosparo generated on the form initialization and the form data validation. The method will return a VerificationResult object.

/**
 * @param array $formData Array with the form values. All not-processed fields by mosparo (hidden, checkbox, 
 *                        radio and so on) have to be removed from this array
 * @param string $mosparoSubmitToken Submit token which mosparo returned on the form initialization
 * @param string $mosparoValidationToken Validation token which mosparo returned after the form was validated
 * @return \Mosparo\ApiClient\VerificationResult Returns a VerificationResult object with the response from mosparo
 * 
 * @throws \Mosparo\ApiClient\Exception Submit or validation token not available.
 * @throws \Mosparo\ApiClient\Exception An error occurred while sending the request to mosparo.
 */
$result = $client->verifySubmission($formData, $mosparoSubmitToken, $mosparoValidationToken);

Request the statistical data

mosparo also has an API method to get the statistical data for a project. You can use the method getStatisticByDate to get the statistical data. You can specify the range in seconds or a start date from which mosparo should return the statistical data. This method will return a StatisticResult object.

/**
 * @param int $range = 0 The range in seconds for which mosparo should return the statistical data (will be rounded up to a full day since mosparo v1.1)
 * @param \DateTime $startDate = null The Start date from which on mosparo should return the statistical data (requires mosparo v1.1)
 * @return \Mosparo\ApiClient\StatisticResult Returns a StatisticResult object with the response from mosparo
 * 
 * @throws \Mosparo\ApiClient\Exception An error occurred while sending the request to mosparo.
 */
$result = $client->getStatisticByDate($range, $startDate);

VerificationResult

Constants

• FIELD_NOT_VERIFIED: 'not-verified'
• FIELD_VALID: 'valid'
• FIELD_INVALID: 'invalid'

isSubmittable(): boolean

Returns true, if the form is submittable. This means that the verification was successful and the form data are valid.

isValid(): boolean

Returns true, if mosparo determined the form as valid. The difference to isSubmittable() is, that this is the original result from mosparo while isSubmittable() also checks if the verification was done correctly.

getVerifiedFields(): array (see Constants)

Returns an array with all verified field keys.

getVerifiedField($key): string (see Constants)

Returns the verification status of one field.

hasIssues(): boolean

Returns true, if there were verification issues.

getIssues(): array

Returns an array with all verification issues.

StatisticResult

getNumberOfValidSubmissions(): int

Returns the total number of valid submissions in the requested date range.

getNumberOfSpamSubmissions(): int

Returns the total number of spam submissions in the requested date range.

getNumbersByDate(): array

Returns an array with all statistical data for the requested time range. The date is the key in the array, while an array is set as a value. The array contains a key numberOfValidSubmissions with the number of valid submissions and a key numberOfSpamSubmissions with the number of spam submissions.
