How would I get values from 2 rows into one - php

Question

I need to access data from 2 different rows returned in the same array
Here is a picture
I need to access first_name and last_name
Here is my script
<?php
ini_set('display_errors', 1);
include_once('db.php'); // database class
$dbase['host'] = 'asdf';
$dbase['user'] = 'asdf';
$dbase['pass'] = 'asdf';
$dbase['name'] = 'asdf';
$db = new DB($dbase);
// SELECT `meta_value` FROM `wp_usermeta` WHERE `meta_key`='password'
$result = $db->query("SELECT * FROM `wp_usermeta` WHERE `meta_key`='user_email'");
while ($row = $result->fetch_array()) {
echo $row['meta_value'];
}
?>
Any help on this issue would be appreciated greatly!

Answer 1

Try this query..
SELECT
wp1.meta_value AS first_name,
wp2.meta_value AS last_name
FROM
wp_usermeta wp1
INNER JOIN
wp_usermeta wp2
ON ( wp1.user_id = wp2.user_id )
WHERE 1
AND wp1.meta_key = "first_name"
AND wp2.meta_key = "last_name";
GROUP BY wp1.user_id;

Answer 2

You're already looping over these rows, just inspect the meta_key.
$fname="";
$lname="";
while ($row = $result->fetch_array())
{
if ($row['meta_key'] == "first_name")
{
$fname = $row['meta_value'];
}
else if ($row['meta_key'] == "last_name")
{
$lname = $row['meta_value'];
}
}
echo $fname . " " . $lname;
lastly, your sql is incorrect:
SELECT * FROM `wp_usermeta` WHERE `user_id` IN (SELECT `user_id` FROM `wp_usermeta` WHERE `meta_key` = 'user_email' AND `meta_value` = "$user_email_passed_in")

Answer 3

In this case the MySQL query that you're doing is wrong.
It might be
$result = $db->query("SELECT * FROM `wp_usermeta` WHERE (`meta_key`='first_name' OR `meta_key`='last_name')");
In this case all rows matching 'first_name' OR 'last_name' in 'meta_key' field will be returned.
I think you'll have to distinguish these fields using also user_id field as discriminant.
