I try to insert data into the database, mysql and it does not give me the else error and no php error or something, 3 days ago I'm trying to find how to do it and nothing, the code is fine, but it throws the error and the database does not receive anything, and phpMyAdmin gives me error in the example INSERT of all the databases that I have, but the other bases with similar code work correctly and that of my base there is no way, I wanted to finish this project today, and it will not be able to be seems, this error left me out, it is more, I have in the same project the users section with the similar code and if you add users.
<?php
require_once('conexion.php');
$nombre = $_POST['nombre'];
$productos = $_POST['productos'];
$telefono = $_POST['telefono'];
$email = $_POST['email'];
$query = "INSERT INTO proveedores (nombre,productos,telefono,email) values('$nombre','$productos','$telefono','$email')";
$resultado = $conexion->query($query);
if($resultado){
header('Location: /TiemposdeCambios/bootstrap/proveedores.php');
} else{echo "errores";}
?><?php
include ('php/conexion.php');
session_start();
if(isset($_SESSION['u_usuario']))
{
echo "session exitosa";
} else
{
header('Location: login.php');
}
