PHP \ MySql query error

Question

i'm having a problem with a php page on my webserver:

Warning: Invalid argument supplied for foreach() in /home/vyhtpnwt/public_html/include/main.php on line 12

Line 12 on the page is:

foreach ($conn->query("SELECT * FROM accountType WHERE id=".$accountTypeID) as $row2) {
$accountType = $row2[$lang['dbLabel']];
if ($row2['expirationDays']==999) {$accountExp = $lang['unlimitedExp'];} else {
//expiration date script!
$accountExp = 0;
}

Considering that:

• $conn works properly on other scripts;

• $accountTypeID is populated and it's = 1;

• he SELECT return 1 result;

• fields expirationDays

• $lang['dbLabel'] and $lang['unlimitedExp'] are correctly populated.

what can be the problem?

Thanks in advance for your precious help!!!

Answer 1

thank you very much for all your suggestions! I finally found the error!!! I was working on Windows server when i wrote the code and remote server is Linux based, for this reason i didn't see a mistake on the uppercase letter of the table name!

Answer 2

You should try this:

$q = $conn->query
("SELECT * FROM
accountType WHERE id=".
$accountTypeID);
$ar = $q->fetch_assoc():

foreach( $ar as $row2)
{
    // your code here
}

Because you haven't actually fetched the array from that code, you simply fetched the mysqli_query object itself, which isn't the array of values you want/need
