Create table:


include "connect_pdo.php";

 checkbox VARCHAR(200) NOT NULL)";

$sq = $pdo->query($sql);

if  ($sq) {
    echo 'created';


$email = $_POST['email'];
$checkbox = $_POST['checkbox'];

// You have to loop through the array of checked box values ...
foreach($check as $entry){
$check .= $entry.",";

try {
include "connect_pdo.php";

$query = $pdo->prepare('INSERT INTO preferences (email, checkbox) VALUES(:email,:check)');

header("Location: preferences.html");
catch(PDOException $e) {
echo 'Error: ' .$e->getMessage();

select_data php


include "connect_pdo.php";

$query = $pdo->prepare("SELECT * FROM preferences");
echo"<table border=\"1\" width\100\">";
while($r = $query->fetch()){

  $test1 = $r[1];
  $test2 = $r[2];
  $test3 = $r[3];



There are several mistakes before we even get to your question.

  1. You posted the title in ALL CAPS WHICH IS KIND OF RUDE (I corrected that)
  2. You posted a mess of unformatted html and expected us to wade through it
  3. You didn't give any indication as to what error you are seeing

Hi sorry abouty the tittle.
Sorry how i posted the html and php i am trying to learn it
i think the error is in create_table.php or insert_pdo.php
