How do I extract a variable from an INSERT query in php? - php

Question

This is for a registration form I have created. I cannot include all of my code, but the program checks for blank fields then format using the preg_match function. Then it INSERTS the info registered
My code is:
<?php
/* connection info */
ini_set('include_path','../../includes');
include("dbinfo.inc");
$cxn = mysqli_connect($host,$user,$password,$dbname)
or die("Couldn't connect to server. error 3");
?>
<?php
/* Program name: Register.php
* Description: Program displays the blank form and checks
* all the form fields for blank fields.
*/
// Insert info into database //
{
foreach($good_data as $field => $value)
{
$good_data[$field] = mysqli_real_escape_string($cxn,$value);
}
$sql = "INSERT INTO UserInfo (user_id, password, first_name, last_name, city, country, email) VALUES ('$good_data[user_id]', '$good_data[password]', '$good_data[first_name]', '$good_data[last_name]', '$good_data[city]', '$good_data[country]', '$good_data[email]')";
$result = mysqli_query($query, $sql) or die ("Couldn't connect to login");
$row = mysqli_fetch($result);
while ($row = mysql_fetch_assoc($result)) {
$sql2 = "UPDATE TimeStamp SET time = CURRENT_TIMESTAMP where user_id='$good_data[user_id]'";
$result2 = mysqli_query($cxn,$sql2) or die("<p>Couldn't Connect to Login</p>");
include('goodReg.inc');
}
{
echo $message;
extract($good_data);
include('register.inc');
exit();
}
}
}
else
{
include("register.inc");
}
?>
How do I move just the variable to the query and not the whole INSERT string?

There's no need to call mysqli_fetch or mysqli_fetch_assoc. Just do the UPDATE query outside of a loop:
$sql = "INSERT INTO UserInfo (user_id, password, first_name, last_name, city, country, email) VALUES ('$good_data[user_id]', '$good_data[password]', '$good_data[first_name]', '$good_data[last_name]', '$good_data[city]', '$good_data[country]', '$good_data[email]')";
mysqli_query($cxn, $sql) or die ("Couldn't insert into UserInfo: " . mysqli_error($cxn));
$sql2 = "UPDATE TimeStamp SET time = CURRENT_TIMESTAMP where user_id='$good_data[user_id]'";
mysqli_query($cxn, $sql2) or die ("Couldn't update TimeStamp: " . mysqli_error($cxn);
include('goodReg.inc');
