A simple form validation example?

[trymeouteh]

I was unable to find a simple web form validation example using Opis JSON Schema. The examples from Opis JSON Schema show the input data to be always in a JSON format.

I wrote this code below which is a simple form, however when I submit the form I get an error, The data (string) must match the type: integer

When I comment out the $_POST input and uncomment the manual input, it does work by I get no errors, but I am unable to use the form to submit the data.

How would one grab form data and process it for Opis JSON Schema is a simple clean way?

Any help will be most appreciated!

PHP code

<form method="post">
	<input name="name" placeholder="Name" value="<?=isset($_POST['name']) ? $_POST['name'] : '' ?>"/>
    <br />
	<input name="age" placeholder="Age" value="<?=isset($_POST['age']) ? $_POST['age'] : '' ?>"/>
	<br />
	<input type="submit" name="mySubmitButton" />
</form>

require 'vendor/autoload.php';





use Opis\JsonSchema\{

//Create a new validator
$myJSONSchemaValidation = new Validator();



//Register our schema
$myJSONSchemaValidation->resolver()->registerFile('http://subdomain.mydomain.com/myschema.json', 'mySchema.json');



if(isset($_POST['mySubmitButton'])) {
    // Manual input
    // $myInput = (object)[
    //     'name' => 'John Doe',
    //     'age' => 18
    // ];

    // $_POST input
    $myInput = (object)[
        'name' => htmlspecialchars($_POST['name']),
        'age' => htmlspecialchars($_POST['age'])
    ];




    //Validate the input
    $result = $myJSONSchemaValidation->validate($myInput, 'http://subdomain.mydomain.com/myschema.json');

    if ($result->isValid()) {
        echo "Valid";
    }

    else {
        print_r((new ErrorFormatter())->format($result->error()));
    }
}
