Error in my config.php code for Heroku app and mysql

Time:04-04

I am using Heroku for PHP. I looked at my Heroku logs and found errors in my config.php code. I am making a spotify clone for my coding portfolio which I made successfully with xampp, apache, mysql. But now I need to showcase it and I have to use Heroku since it is free and secure. I added the add on for cleardb mysql in Heroku and connected the MySQL workbench and dumped the SQL. However running my app on heroku I get this error, "This page isn’t working right nowslotifyhokole.herokuapp.com can't currently handle this request. HTTP ERROR 500"

My config php code:

<?php
$url = parse_url(getenv("mysql://bde1900971353c:[email protected]/heroku_d347ebb2241490f?reconnect=true"));

$server = "us-cdbr-east-05.cleardb.net";
$username = "bde1900971353c";
$password = "2b4ac360";
$db = substr("heroku_d347ebb2241490f", 1);

$conn = new mysqli($server, $username, $password, $db);
?>

My heroku logs.

Before you do anything else, rotate those credentials. Editing them out of your question is not enough. You have published them online and they are forever compromised.


The whole point of using getenv() for credentials is so you don't have to include them in your source code. The argument to getenv() shouldn't be your database URL; it should be the name of an environment variable that contains your database URL.

The ClearDB add-on sets such a variable for you: CLEARDB_DATABASE_URL.

<?php

$url = parse_url(getenv("CLEARDB_DATABASE_URL"));

Unfortunately, it doesn't look like MySQLi knows how to connect via a URL directly, so you're right to pull the URL apart and pass individual values into the constructor.

But you need to do it from the URL you have just loaded from the environment instead of hard-coding values. You've already called parse_url() on the URL string, so you should already have what you need.

Something like this should work:

$server = $url["host"];
$username = $url["user"];
$password = $url["pass"];
$db = substr($url["path"], 1);

$conn = new mysqli($server, $username, $password, $db);

CodePudding user response:

Sorry, but I just figured out why it wouldn't work. I didn't deploy to the main branch. I had to deploy it first.
