I created this code to add products to my database, only that there is an error in the image, says I did not set it.

the code is this:

<?php   
ob_start();
session_start();
require 'ligarDb.php';


$error = false;
$nameError ="";
$imagem ="";


 if(isset($_POST['btn-add'])){ 


        $nameP = trim($_POST['nameP']);// o trim elimina espaços na string 
        $nameP = strip_tags($nameP);// Retira as tags HTML e PHP de uma string
        $nameP = htmlspecialchars($nameP);// Converte caracteres especiais para a realidade HTML

        $preco = trim($_POST['preco']);
        $preco = strip_tags($preco);
        $preco = htmlspecialchars($preco);

        $size = trim($_POST['size']); 
        $size = strip_tags($size);
        $size = htmlspecialchars($size); 

        $estado = trim($_POST['estado']);
        $estado = strip_tags ($estado);
        $estado = htmlspecialchars($estado);

        $cor = trim($_POST['cor']);
        $cor = strip_tags($cor);
        $cor = htmlspecialchars($cor);

        $descricao = trim($_POST['descricao']);
        $descricao = strip_tags($descricao);
        $descricao = htmlspecialchars($descricao);

        $imagem  = $_FILES['foto']['name'];
        $img_dir = $_FILES['foto']['tmp_name'];
        $imgSize = $_FILES['foto']['size'];


 //validação do Nome Produto

    if(empty($nameP)){
                 $error = true;
                 $nameError = "Preencha o nome.";
    }else if (strlen($nameP) < 3) {
                 $error = true;
                 $nameError = "Nome tem de ter mais caracteres.";
    } else if (empty($imagem)) {
                $error = true;
                $imgError = "Por favor selecione uma imagem.";
    } else {

        $upload_dir = '../upload/'; //diretório onde será guardada a imagem.
        $imgExt = strtolower(pathinfo($imagem, PATHINFO_EXTENSION));
    //validação de extensao 

        $valid_ext = array('jpeg','jpg','png');
    // 
        $user_pic = rand(1000,1000000)." . ".$imgExt;

    // valida os formatos das imagens
        if(in_array($imgExt, $valid_ext)){
            //verifica se o tamanho é de 5MB
            if($imgSize < 5000000 ){
                move_uploaded_file($img_dir,$upload_dir.$user_pic);
            } else {
                $imgError = "Desculpa, a sua imagem é muito grande.";
            }
        }  else {
            $imgError = "Desculpe, apenas extesões JPG, JPEG, PNG.";
        }

    }

 if(!$error){  

$addnew = mysqli_query($ligacao, "INSERT INTO products (nomeP,preco,estado,tamanho,cor,descricao, imagem) VALUES ('$nameP','$preco','$estado','$size','$cor','$descricao', '$user_pic')");

    if($addnew) {
          $errTyp = "successo";
          $errMSG = "Registrado com sucesso.";
          header('refresh: 10; form_addnew.php');
              unset($nameP);
              unset($preco);
              unset($size);
              unset($estado);
              unset($cor);
              unset($descricao);
              unset($user_pic);
   } else {
    $errTyp = "Erro";
    $errMSG = "Tem algo errado, tente mais tarde..."; 
   } 

  }
}

The error presented is this:

is referring to that part of the code $image = $_FILES['photo']['name']; //39 $img_dir = $_FILES['photo']['tmp_name']; // 40 $imgSize = $_FILES['photo']['size']; // 41

Jolene, the ideal is to put the error in the question by editing it. But I already put the error there, so you can leave.

William solved this way... $image = isset($_FILE['photo']['name']), so now it does not register in the database :(

Jolene, you actually solved the mistake. The error happens because this data referring to the upload of the photo for some reason is not being saved and it tries to access a data that does not exist. now it just doesn’t save the die. but that data still doesn’t show up. I’ll try to check the reason here and answer.

The only error I found in your code was in the section below, where the enctype="Multipart/form-data" is not with " (quotation marks) correctly.

The insertion of this attribute in the form to make the file upload work. What was happening is that because of the wrong quotes he was not being recognized, as excerpt below in his code.

<form id="my-login-form" method="post" action="" enctype=”multipart/form-data”>

Please correct the excerpt by quotation marks according to the section below and make sure it worked:

<form id="my-login-form" method="post" action="" enctype="multipart/form-data">
