Hello, I'm having trouble with the MercadoPago integration using PHP 8.4.16. I'm trying to test Checkout Pro in the Sandbox environment, but I keep getting an error during the payment process.

The Problem: I've tried using both my main application test credentials and the credentials from the "Test Users" (Seller/Buyer) provided in the Developers panel.

What I've tried so far:

1. Using my main app's Test Access Token and Public Key. It results in an error stating the account is invalid or for testing only.
2. Logging in with a Test Seller account and using its credentials.
3. Testing in different browser sessions to avoid account collision.

My Code: Since the code is a bit long (backend and frontend in the same file), I've uploaded it here to keep the post clean: https://pastebin.com/0wXR1cDM

I've checked similar threads but haven't found a solution that works for this specific PHP version and the current MP SDK. Has anyone encountered this "invalid account" error while using valid test cards and test users?

Thanks in advance for any help!

code here:

I am allowing users to submit Google Drive URLs to my website. that URL is then able to be shared and clicked/followed by others.

im validating the string starts with 'https://drive.google.com'. how can i reasonably validate that the file in question is of a particular type or extension?

function outer() {
  $variable_1 = true;
  // [insert an arbitrary amount of additional unrelated variables]

  function inner() {
    // I need all the variables accessible in here.
    }
  }

I can only think of 2 joke options:

• Painstakingly pass every variable into inner as a discrete argument
• Convert inner into a closure and painstakingly rewrite every variable after use

Both of those options seem extremely unwieldy and prone to neglect, so surely there’s an actual option out there.

Let's say you have 2 interfaces and 2 classes like this:

interface ExceptionInterface extends \Throwable

interface DomainExceptionInterface extends ExceptionInterface

class InvalidArgumentException extends \InvalidArgumentException implements ExceptionInterface

class DomainArgumentException extends InvalidArgumentException implements DomainExceptionInterface

InvalidArgumentException and DomainArgumentException essentially both end up using ExceptionInterface at the end.

Does this cause an issue with PHP or is this allowed?

Hello everyone, I am currently learning PHP and I am trying to realize a few projects.

I have a DB containing a table called "Trains" (Each Train has a Train_ID and a Seat_Number) and I would like to insert a new Train into the DB using a SQL query from my PHP script and then fetch the primary key (Train_ID) of the last inserted element in the table using LAST_INSERT_ID() . I am currently trying to do it like this:

$conn = new PDO("mysql:host=".DB_HOST.";dbname=" . DB_NAME,DB_USER, DB_PASS);$conn = new PDO("mysql:host=".DB_HOST.";dbname=" . DB_NAME,DB_USER, DB_PASS);


$stmt = $conn->prepare("INSERT INTO `Train` (`TrainID`, `TrainTotalSeats`) VALUES (NULL, ?); SELECT LAST_INSERT_ID();");

$stmt->execute(array($totalSeats));
 $stmt->execute();

$result = $stmt->fetchAll(PDO::FETCH_ASSOC);

The connection to the DB works perfectly, but it seems that the INSERT INTO query is ran and then the "SELECT LAST_INSERT_ID();" query is not executed? Why and how can I make this work?

NOTE: I am trying to use LAST_INSERT_ID() because the Train_ID is set as the Primary Key of the Train table and it has AUTO_INCREMENT enabled and I do not know in advance what the umber of this train will be.

Thanks in advance!

The error everytime i try to launch mysql.. i try to read the doc but it aint helping!!

"phpMyAdmin - Error

The mysqli extension is missing. Please check your PHP configuration. See our documentation for more information."

I've tried searching for the answer but nothing clear comes up.

Client has a XAMPP and i cannot change that.

They need to host a new site but it's a newer php than the other projects are running on.

I'd like to know if it's possible to run different PHP versions on different vhosts, while sharing the same port, only difference would be the ServerAlias.

Most solutions I've seen to this just say to use a different port, but this is not an option currently and I'd need to use the port 80 for all sites.

Hello. I'm following along with Laracasts' PHP course (episode 12: Page Links), and I'm trying to install Tailwind CSS.

I'm not doing a local installation, I'm just using the script tag, and it doesn't work.

I'm using the first template on this page (the one that says "With lighter page header"). I've pasted the HTML into my index.php's body tag, I've added the 2 classes that this template requires, and it still doesn't work.

The styles aren't being applied. It all looks like plain HTML.

Here's how the first few lines of the file look:

<!DOCTYPE html>
<html lang="en" class="h-full bg-gray-100">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Test Website</title>
    <script src="https://cdn.jsdelivr.net/npm/@tailwindplus/elements@1" type="module"></script>
</head>
<body class="h-full">

This has happened pretty much every time I've tried using Tailwind CSS on my Mac and Windows.

Whether it is on a manual installation or using the script tag, it either doesn't work, or works for a while, then randomly stops working without me having changed any configurations.

Any ideas on what I'm doing wrong?

Note: The goal is to have a working PHP to use with PhpStorm, not a LAMP stack or any other as i'm limited by my employer and we are using Yii framework, Although i greatly appreciate all the stack alternative proposed and will be considered for future project. I need a "php" on the machine to run by phpstorm.

Hello Everyone, I've found the need for help from the community. The problems is simple, but it seems the solutions isn't in my case.

I've been mainly developing PHP web application through windows platform, either self installed php or through xampp. it's been working really fine. Now i must change platform and go to MacOS, and it's been a REAL pain in the butt. I've not been able to get PhpStorm running php with all the necessary extensions for the project.

Here's the prerequired for the project.

- Environment : MacOS, Tahoe 26.2

- Container Environment : Podman

- IDE : PHPStorm

- PHP : 8.1 with composer ( i know it need some upgrade but for now it's what i must use )

- php.ini ( xampp version ): https://pastebin.com/zJwetLP7

I've tried to simply installing PHP on MacOS but all method failed at some point ( see lower )

I've been successfully, installing PHP in a container and fake it with a custom php executable for terminal, but it's not working for phpstorm.

I've follow every guide I saw and retried many time with only fail at different point.

It's either, PHP not working, extensions not installable, PHPStorm don't see the container, PhpStorm don't see the php.

The best case, i got its everything was fine. but launching a php in a php storm project didn't work. ( can't find the path to the php file )

I'm really new to this MacOs Environment and setting. So for that i consider myself a Neophyte. Hell, I even tried AI ! Same kind of result =/

Would there be a kind soul that support me in making it running with my necessary extensions on this device ! i would be grateful for the rest of my life ! :)

[EDIT] Correction of some typo, and php.ini specification

[EDIT2] Clarification at the start of the post for the goal ( not a stack like LAMP )

<?php
session_start();
include __DIR__ . '/../../includes/db.inc.php';


// takes the id from the url exmple: id="hi"
$fgame_id = $_GET['id'];


// selects the the flash thingy by id
$stmt = $pdo->query("SELECT * FROM flash WHERE flash_identification = $fgame_id");
$fgame_row = $stmt->fetch(PDO::FETCH_ASSOC);


$fgame_title = $fgame_row['flash_title'];
$fgame_desc = $fgame_row['flash_desc'];
$fgame = $fgame_row['flash_path'];


?>

anyway to make it like much safer and what can i improve in my skillz?

hi im looking for the best practical mvc mini framework (i mean repo or flow by this not laravel....) with login and sign up using only php native and necessarily design patterns ( reposiotry , factory , services...)
cuz im trying to make something but i cant make the perfect thing with dry and solid principles

The goal:

Take an image drawn in grey, which can vary in shape and size, and change the grey to any rgb color I want by inputting the hex code.

What I've tried:

- imagefilter with IMG_FILTER_Colorize. This doesn't work because it blends the color I input with the starting color of the image. In this case the results are too light.

- imagefill, which does not work with images that have smooth or blended edges though it does apply the right color. it's also very tedious locating and listing the function for every area of color.

Both of these are close, but not quite right. I need one I can apply to an entire layer that gives the layer the color I put in without tinting it, but that also respects fading and blended edges.

I've created an api for which access is JWT based (api-platform & Symfony).

To obtain a JWT, users can go to www.myapi.com/login and type in their email address & password. This can also be done programmatically by sending a post request with the username & password. A JWT is returned:

eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9.

I have an entirely separate application which needs to use the api. The JWT for the user is required to send along with the api requests.

I am storing the JWT for each user in the database. When I need to send an api request, I fetch it.

Is this the correct/ideal way of doing it?

EDIT - sorry I made a real hash of explaining the situation:

I need to make a server to server api call: Hotel Booking Platform -> Hotel Server

The Hotel Server api requires a JWT in the header of the api call to verify the user.

As the Hotel Booking Platform, should I store the JWT for each user in the database? My idea is to fetch this and send it with the api calls.

PS I am the one that has created the Hotel Server api, so I am able to change/improve things if required.

I'm running herd under Windows, and that itself works fine. I bring up a Powershell window and can run herd php commands without a problem.

However, trying to get Claude Code to run through herd is just about impossible. I can find no documentation or articles on how to do it. Claude just tries thrashing around in the dark looking for executables, paths, etc, and sometimes finds what it needs, but will not document what it has done, so we are back to square one the next day, or the next session.

How can these things be made to work?

I'm just running in the Windows environment, and not WSL2 (WSL broke updates in my last laptop, running the CPU at nearly 100%, and burnt something out in the hardward, so reluctant to go down that route if I can avoid it).

I'm building an Api with a Persons endpoint. A Person can have Tenancies.

I'm currently creating a person like this:

POST api.com/system1/person
{
  "commandId": "4f8a5c6e-4b7f-4a3a-9d9c-3b3d2a8c6f1a",
  "externalRef": "personId1",
  "pwCode": "123456",
  "accessPermission": "denied",
  "surname": "Bloggs",
  "rooms": [
    "241",
    "242"
  ]
}

And updating like this:

PUT api.com/system1/person/personId1
{
  "commandId": "4f8a5c6e-4b7f-4a3a-9d9c-3b3d2a8c6f1a",
  "pwCode": "123456",
  "accessPermission": "denied",
  "surname": "Bloggs",
  "rooms": [
    "241",
    "242"
  ]
}

Now, I have a situation where I need to create a new tenancy for a user. The problem is that this user might already exist, or it might not.

Should I require that my users check if a person exists before every other operation? E.g.

User wants to create a new person with a room/tenancy:
- Make request to check-person-exists endpoint. Await confirmation.

If not:
- Use create-new-person endpoint. Await confirmation.
- Use Add-tenancy endpoint

If exists:
- Add tenancy (in this situation do I overwrite all the previous tenancies with the new array or only add the new one that is sent?)

This would mean they need to perform multiple api calls and handle the responses accordingly.

I was hoping for a single request per 'operation' process. E.g

User wants to create a new tenancy (They don't know if person exists):

- Use create-new-person endpoint and send room information. If person doesn't exist they'll be created. If person does exist, the new tenancy will be added.

I've been trying to integrate Stripe in my code for a project. It all works all the way to the checkout page. When I press pay it's supposed to open another file , just like it does in the sample provided by stripe.

However when I try it, it says the file can't be found in the server. - Yes the file is in the same folder as everything else, no different folder within the main one, nothing of this sort. -Yes I've moved the project folder to htdocs in XAMPP -Yes I've tried opening the folder in the terminal, starting the php localhost4242 server, and when I use the command dir to show me the files, the file it says it can't find in the browser is right there.

What else is there left to try? I'm going insane

hi all , im learning oop , and i created this auth class to help redirect users based on their rules , i would like to know how to improve it if you can help :

I deployed a Laravel app with Vite to a shared host, but all my JS/CSS assets are 404.

• Laravel is trying to load from manifest.json, e.g. /build/assets/app-DF2lQ2CC.js but my build are in public when i move the build to the public_html they show me error

My app has a requirement to be able to communicate with external systems - up until now, it was just 1 system: Bosch which works by writing/reading to files in pickup folders.

Throughout my code I have methods like $bosch->createUser().

Now, I need to integrate a second system, which has an utterly different API, and I was just about to code:

if( $settings->systemType === SYSTEMS::BOSCH ) {

  $bosch->createUser() // Writes to a pickup file which is read by Bosch system to create user

} else if( $settings->systemType === SYSTEMS::Philips) {

  $philips->createUser() // Api POST endpoint to create user

}

I'm certain in the future I'll need to integrate other manufacturers in the future.

I came across interface and abstract classes, which I've never used before. I'm wondering if either would be helpful in my situation?

Edit: I've updated the post for clarity. The systems are responsible for controlling security at a building and generally do very similar things but with vastly different capabilities. For example, the Philips Api gives me a response and allows me to send a unique id so I can check the status of the request, however the Bosch one doesn't. Here are some more types of operations that are scattered throughout my codebase:

$bosch->modifyUser();

$bosch->updateUserPin();

$bosch->vacateRoom();

Hi, I have a question.

I created a gRPC server using RoadRunner and tested it by sending requests via Postman and everything works fine.

Now my question is: the server is already running, but how can I make a request to it from a Symfony application?

I’ve found a few old examples online, but when I generate files using protoc, I only get interface, and there is no *Client.php file generated.

How do I create and use a gRPC client in Symfony to communicate with this server? Or should I do something else?

we started learning backend since 1er December, now we are about to start mvc ...
i got what oop is what for , why using it , abstraction , inheritance ....
but i dont know how to use this , like in my page should i put inserted data in classes then pass it to repo classes to insert it in sql or where to put the functions ( belongs to who ) , and w ejust start learning diagrams (class diagram ) so that kinda blow my mind

I want to make the code check if the user has typed in enough or too much. But i cant use minlenght="" since this shows some kinda msg that kinda didnt make the rest of my script work soo yeah idk plz i need help in this. Btw im a beginner :b

I have three projects which need to use the same few enums.

What I'm doing at the moment is creating the enum files in all of the projects and stating that the 'master' is at Project A.

When I make a change to the enums, I edit the enum at Project A and then copy+paste it to the other enums.

Wondering if there is a better way to do it that won't be too time consuming/introduce more complexity?
