Question
I am testing Paypal's masspay using their 'MassPay NVP example' and I having difficulty trying to amend the code so inputs data from my MySql database.
Basically I have user table in MySql which contains email address, status of payment (paid,unpaid) and balance.
CREATE TABLE `users` (
`user_id` int(10) unsigned NOT NULL auto_increment,
`email` varchar(100) collate latin1_general_ci NOT NULL,
`status` enum('unpaid','paid') collate latin1_general_ci NOT NULL default 'unpaid',
`balance` int(10) NOT NULL default '0',
PRIMARY KEY (`user_id`)
) ENGINE=MyISAM AUTO_INCREMENT=6 DEFAULT CHARSET=latin1 COLLATE=latin1_general_ci
Data :
1 test1@example.net paid 100
2 test2@example.net unpaid 11
3 test3@example.net unpaid 20
4 test4@example.net unpaid 1
5 test5@example.net unpaid 20
6 test6@example.net unpaid 15
I then have created a query which selects users with an unpaid balance of $10 and above :
$conn = db_connect();
$query=$conn->query("SELECT * from users WHERE
balance >='10'
AND status = ('unpaid')");
What I would like to is for each record returned from the query for it to populate the code below:
Now the code which I believe I need to amend is as follows:
for($i = 0; $i < 3; $i++) {
$receiverData = array( 'receiverEmail' => "user$i@paypal.com",
'amount' => "example_amount",);
$receiversArray[$i] = $receiverData;
}
However I just can't get it to work, I have tried using mysqli_fetch_array and then replaced "user$i@paypal.com" with $row['email'] and "example_amount" with row['balance'] in various methods of coding but it doesn't work. Also I need it to loop to however many rows that were retrieved from the query as <3 in the for loop above.
So the end result I am looking for is for the $nvpStr string to pass with something like this:
$nvpStr = "&EMAILSUBJECT=test&RECEIVERTYPE=EmailAddress&CURRENCYCODE=USD&L_EMAIL0=$test2@example.net&L_Amt=11&L_EMAIL1=$test3@example.net&L_Amt=11&L_EMAIL2=$test3@example.net&L_Amt=20&L_EMAIL3=$test5@example.net&L_Amt=20&L_EMAIL0=$test6@example.net&L_Amt=15";
Thanks
Solution
I have resolved the issue after some trial and error:
<?php
$nvpStr="&EMAILSUBJECT=$emailSubject&RECEIVERTYPE=$receiverType&CURRENCYCODE=$currency";
$conn = db_connect();
$query=$conn->query("SELECT email,balance from users WHERE
balance >='10'
AND status = ('unpaid')");
$i = 0;
while ($i <= mysqli_fetch_row) {
while($row = mysqli_fetch_object($query)) {
$nvpStr.="&L_EMAIL$i=$row->email&L_Amt$i=$row->balance";
$i++;
}
}
?>
