Have a MySQL Database, PHP Form isn't working, but connection is Successful

Question

I created a PHP form, and I would like to record the results to a database. When I test the connection file on its own it is successful. When I attempt to include the file with the connection instead, the form does not save the information? Am I missing a step here?

Updates: The first thing I had to discover was to use MYSQLi instead of MYSQL (Abandoned the PHP route a long time ago). So instead of compounding my issues, I am trying to troubleshoot the connection in one file first.

    <?php

$conn = new mysqli('localhost', '*****', '*****', '******');


if($conn->connect_errno > 0){
    die('Unable to connect to database [' . $conn->connect_error . ']');


} else {
    echo "Have a good night!";
}


error_reporting(E_ALL);

$query = "SELECT id AS txt FROM `Pages`";
$result = $conn->query($query);

if($result === false) {
  trigger_error('Wrong SQL: ' . $query . ' Error: ' . $conn->error, E_USER_ERROR);
} else {
    $result->data_seek(0);
    while($row = $result->fetch_assoc()){
        echo $row['txt'] . '<br>';
    }  
}

$result->free();
$conn->close();

?>

This updated code now returns this error: Have a good night!

Warning: mysqli::query(): Couldn't fetch mysqli in /home/******/public_html/file.php on line 18

Fatal error: Call to a member function data_seek() on a non-object in /home/*******/public_html/file.php on line 23

Answer 1

Your <input type="submit" id="add" value="Save"> should have name="add" . Also, it is not good to use the old mysql interface. Use mysqli or pdo.

Answer 2

please change this code with your code

 <?php

    $conn = new mysqli('localhost', '*****', '*****', '******');

    if($conn->connect_errno > 0){
        die('Unable to connect to database [' . $conn->connect_error . ']');

use $conn through out it shows, you use new variable $db
