Problem when inserting data into DB

Question

Hi everyone!

I do not know what happened to my code, I have trouble inserting data into the database and yet I have no errors

here is my code:

<?php
     include_once('config.php');

     if(isset($_POST['submit'])){
    $nom=isset($_POST['nom']);
    $prenom=isset($_POST['prenom']);

    $phone=isset($_POST['phone']);
    $naissance=isset($_POST['naissance']);
    $lieu=isset($_POST['lieu']);
    $nationalite=isset($_POST['nationalite']);
    $passport=isset($_POST['passport']);

    $ckckl[]=isset($_POST['chkl[]']) ;

    $tmp=isset($_FILES['photo']['tmp_name']);
        $img=isset($_FILES['photo']['name']);
        $type=isset($_FILES['photo']['type']);
        if (is_uploaded_file($tmp)) {
            if (!strstr($type,'jpg') && !strstr($type,'png')){
                echo "Ooops! veuillez choisir une image";
            }
            if (!move_uploaded_file($tmp,"./dist/img/$img")) {
                echo "Désolé,destinantion non trouvée!";
            }




    $query="INSERT INTO pelerin (nom,prenom,genre,dateNaissance,lieuNaissance,nationalite,numPassport,photo) VALUES ('".$nom."','".$prenom."','".$genre."','".$phone."','".$naissance."','".$lieu."','".$nationalite."','".$passport."','".$img."')";
         mysqli_query($conn,$query);

         echo "Record is inserted";

 }
  }
 ?>
