Fetching PDO - $handler vs $stmt? - php

Question

I am VERY new to PHP / PDO, so please be gentle...
I am trying to enter code into my database and then fetch it into a webpage. I am able to do the first but am having difficulty displaying it. I am wondering if it's because i'm trying to combine $stmt and $handler together?
This is my code for entering the information into the database:
try {
$conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
// set the PDO error mode to exception
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
// prepare sql and bind parameters
$stmt = $conn->prepare("INSERT INTO survey (storename, receipt, date_visit)
VALUES (:storename, :receipt, :date_visit)");
$stmt->bindParam(':storename', $storename);
$stmt->bindParam(':receipt', $receipt);
$stmt->bindParam(':date_visit', $date_visit);
// insert a row
$storename = $_POST['storename'];
$receipt = $_POST['receipt'];
$date_visit = $_POST['date_visit'];
}
catch(PDOException $e)
{
echo "Error: " . $e->getMessage();
}
$conn = null;
It works perfectly.
This is my code for fetching information from my database.
<?php
try {
$handler = new PDO('mysql:host=localhost;dbname=test', 'test', 'test');
$handler->setAttribute(PDO::ATRR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch(PDOException $e) {
echo $e->getMessage();
die();
}
class SurveyEntry {
public $id, $storename, $receipt, $date_visited,
$entry;
public function __construct() {
$this->entry = "{$this->storename} posted: {$this->receipt}";
}
}
$query = $handler->query('SELECT * FROM survey');
$query->setFetchMode(PDO::FETCH_CLASS, 'SurveyEntry');
while($r = $query->fetch()) {
echo $r->entry, '<br>';
}
?>
I can confirm that it connects correctly, but I can't get it to display any information. I'm wondering if it's something to do with the difference in $stmt and $handler that i'm using? I've been following tutorials online and have quite possibly mixed 2 tutorials together to try and achieve what i'm looking for.
UPDATE:
I managed to get it to work by updating how I called from the database:
$host = "localhost";
$dbname = "test";
$user = "test";
$password = "test";
$handler = new PDO( "mysql:dbname=$dbname;host=$host" , $user , $password );

Answer 1

Figured it out - I had 'ATRR_ERRMODE' instead of 'ATTR_ERRMODE' (typo)

Answer 2

how are you?
You should try to fix it:
1- Two different connections:
$conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
$handler = new PDO('mysql:host=localhost;dbname=test', 'test', 'test');
