Question

PHP - Validation

Add validation that checks:

$title and $message both have a minimum length of 3.

title has a maximum length of 32 characters.

$message has a maximum length of 52 characters.

If any of the three validation rules fail, print a status of 432 and an error message of what is wrong with the user input. The JSON response should look like:

{“status”: 432, “error”: “title field is too short”}

If the user submitted a successful post, save the record using the provided Thread class. Set the timeposted set to when the item was submitted. Make the thread visible as soon as its submitted. Print a status code of 200. The JSON response should look like:

{“status”: 200}

Add your code to newthread.php. Test your script by running:

php newthread.php "My Title Here" "My Message here"

newthread.php

<?php

require_once(__DIR__ . '/init.php');

if ($argc != 3)
{
    throw new Exception('Invalid number of arguments provided');
}

$title = $argv[1];
$message = $argv[2];

$thread = new Thread();

// Actual implementation below
