PHP retrieve data from table row and store to variable - php

Question

i guess the questions says it all. The result of my query results into a row which will match the condition. I want to get each data from each table column and put into a variable.
$getinfo = "select
user_firstname,
user_middlename,
user_lastname
from tempuserinfo
where user_email ='$ead'
and activation_code='$eac'";
$query = mysql_query($getinfo, $db);
if(!$query) {
echo'something went wrong.';
} else {
//put them into variables
$firstname = mysql_fetch_object($query, 'user_firstname');
$middlename = mysql_fetch_object($query, 'user_middlename');
$lastname = mysql_fetch_object($query, 'user_lastname');
}

Answer 1

If you are getting multiple results, you can loop through them like this:
$getinfo = "select user_firstname, user_middlename, user_lastname from tempuserinfo where user_email ='$ead' and activation_code='$eac'";
$query = mysql_query($getinfo, $db);
while ($row = mysql_fetch_array($query)) {
$firstname = $row['user_firstname'];
$lastname = $row['user_lastname'];
}
If you are only getting one row back (make sure you add a LIMIT to your SQL statement), then you can use something like this:
$getinfo = "select user_firstname, user_middlename, user_lastname from tempuserinfo where user_email ='$ead' and activation_code='$eac'";
$query = mysql_query($getinfo, $db);
$row = mysql_fetch_array($query);
$firstname = $row['user_firstname'];
$lastname = $row['user_lastname'];

Answer 2

mysql_* function are deprecated. In documentation its recommended like in latest versions of PHP they are going to use mysqli_* or PDO.
Below are the script using mysqli for your question:
$mysqli = new mysqli("localhost", "root_user", "root_password", "database");
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
$getinfo = "select
user_firstname,
user_middlename,
user_lastname
from tempuserinfo
where user_email ='$ead'
and activation_code='$eac'";
if ($result = $mysqli->query($getinfo)) {
while ($row = $result->fetch_object()) {
$firstname = $row->user_firstname;
$middlename = $row->user_middlename;
$lastname =$row->user_lastname;
}
$result->close();
}
else
{
echo'something went wrong.';
}

Answer 3

an example with mysqli, mysql as this deprecated
$sql = "select user_firstname, user_middlename, user_lastname from tempuserinfo where user_email ='$ead' and activation_code='$eac'";
$query = mysqli_query($conn, $sql);
while($rs = mysqli_fetch_assoc($query)){
$user_firstname = $rs['user_firstname'];
$user_middlename = $rs['user_middlename'];
$user_lastname = $rs['user_lastname'];
}
if you want to have all fields in order to consult them later, add them to an array
$i=0;
while($rs = mysqli_fetch_assoc($query)){
$data[$i] = array('user_firstname'=>$rs['user_firstname'], 'user_middlename'=>$rs['user_middlename'], 'user_lastname'=> $rs['user_lastname']);
$i++;
}
print_r($data);

Answer 4

This should work:
$result = mysql_fetch_object($query);
$firstname = $result->user_firstname;
$middlename = $result->user_middlename;
$lastname = $result->user_lastname;
BUT:
Use MySQLi or PDO sintead mysql module is deprecated already

Answer 5

$dsn = 'mysql:dbname=testdb;host=127.0.0.1';
$user = 'dbuser';
$password = 'dbpass';
try {
$dbh = new PDO($dsn, $user, $password);
} catch (PDOException $e) {
echo 'Connection failed: ' . $e->getMessage();
}
try {
$sth = $dbh->prepare("select user_firstname, user_middlename, user_lastname from tempuserinfo where user_email = ? and activation_code=?");
$sth->execute(array($ead,$eac));
$row = $sth->fetch(PDO::FETCH_BOTH);
$user_firstname = $row['user_firstname'];
$user_middlename = $row['user_middlename'];
$user_lastname = $row['user_lastname'];
} catch (PDOException $e) {
echo 'Database operation failed: ' . $e->getMessage();
}
Really, do learn to use PDO, because it is as easy as using mysql_*, but much safer and better.
