php script to make random code needs more options (read info)

Ok, let me first start with this: I have posted this project 3 times and each time people dont read the specs i need and just use a copy and pasted messaged with nothing to do with my needs and also IMHO are just spamming the site and most cant speak english. english is a MUST!! I have a membeship site that uses the script "amember" you can google it. i have a script that when a user buys a membership, they are taken back to their profile page and a message is there to make a code for their membership. At present this will ONLY make one code and copies that code to a txt file for me to read. The tree for this code is this: customer buys a product/membership is taken to payment and completes checkout their details are copied into a file called "used_products" (be great to rename this) in this format // Get list of used products $prodids = file_get_contents(__DIR__ . "/[login to view URL]"); $name = Am_Lite::getInstance()->getName(); foreach (Am_Lite::getInstance()->getAccess() as $a) { if ((strtotime($a['expire_date']) > strtotime("today")) && (!strstr($prodids, " - $a[access_id]\n"))) { $access_id = $a['access_id']; $prod_id = $a['product_id']; $user_id = $a['user_id']; $expiry = $a['expire_date']; $begin = $a['begin_date']; } } User: 85 Begin: 2016-03-01 Exp: 2016-04-01 IP: 92.238.x.x - 468 User gets the option on what code to make and shown on screen s the code for them to copy and this is then converted format to a txt file for me to read. There is also a button on that page, that is the same script. If a user clicks it , the script checks the txt file as above and if not paid get a error, if paid can make a code. The trouble is, only one code can be made. i need the script changed that it knows by prouduct id that it can make more than 1. example product 1, make 1 code and copy 1 code product 11 make and show 2 codes and copy 2 codes to txt file i need to be able in the code to change id`s for my needs and lines that can be made. as someone may buy 10 memberships and i want them to be able to make 10 codes. the files for this was made from a user on here, within 2 hours and only charged £60. 3 files is what this uses. One is the custom thank you return after payment that "amember" uses with some code to take them to the code making screen. The codgen script. very small with some parts i can edit and of course the txt file it reads to confirm payment is made and allow code to be made. offers above £100 will be classed as spam and proves not read here as 90% of the work is more than likey done. As i have spare time this week, i can show you over teamveiwer how the script works. To prove to me that you have read all the the specs, first line of your message must say: " more coding needed to php file" if this is not there and rubbish about you make this , make that, see demo here, will just be removed.
