Unable to insert information in MySql database

[Gyoumu]

Hello everyone,
first of all, here is my username as it is recommended to share: epiz_25903923

Situation
I recently restarted to code in php for a website that I want to connect to a database. Everything was working perfectly on my local environment with WAMP Server.
I was able to create a database via the Infinityfree control panel, inputed some data inside, was able to connect this database to my php that I uploaded on my website hosted by Infinityfree. Everything was fine until I tried to INSERT data to my database.
I spent the last 3 days looking everywhere, but I can’t find the solution to my problem.

Database
Here is the structure of my database (I start with an easy one, also tried with id but this did not seem to matter here) :

CREATE TABLE test (name varchar(256) not null);

PHP code

<?php

$dbServername = "sql101.epizy.com";
$dbUsername = "epiz_xxxxxxx";
$dbPassword = "xxxxxxxxx";
$dbName = "epiz_xxxxxxx_test";

$conn = mysqli_connect($dbServername,$dbUsername,$dbPassword,$dbName);

$name="Bob";

$sql = "INSERT INTO test (name) VALUES ($name);";

$worked=mysqli_query($conn,$sql);

if (!$worked) 
{
    echo "Error : cannot add to database";
}
else
{
    echo "no problem";
}      
?>

Error message

I activated the Alter PHP config on the Control Panel, because it might help to debug in the future.
However, with this simple code I only get the "Error : cannot add to database" message and in fact no row is added to my database…

This code and even the more complicated codes I prepared for my website do work on WAMP on my local environement, but this simple one does not work once on Infinityfree. However I can get data from the database … I don’t get it

Thank you very much if you read all this and I pray for someone to help me find the answer, I’m so sad right now ^^

Hello @Gyoumu! I solved your problem. Here is the final code:

<?php $dbServername = "sample"; $dbUsername = "sample"; $dbPassword = ""; $dbName = "sample";
 $conn = mysqli_connect($dbServername,$dbUsername,$dbPassword,$dbName); $name="Bob"; 

$sql = "INSERT INTO test(name) VALUES ('$name');"; 

$worked= mysqli_query($conn,$sql); 

if (!$worked) { echo "Error : cannot add to database"; } else { echo "no problem"; } 

?>

Pls be careful to php syntax.

The problem is here in this line:

@Gyoumu

$sql = “INSERT INTO test (name) VALUES ($name);”;

So I replaced them with:
$sql = “INSERT INTO test(name) VALUES (‘$name’);”;

@Gyoumu

echo “Error : cannot add to database”;

To see the error, it must be:

echo "Error : cannot add to database: ".mysqli_errno($conn);

I guess the code should look like this:

INSERT INTO `test` (name) VALUES ('".$name."');

And test table must exist.

@JavesPotato @anon19508339,
