You need to specify the API credentials at the time of PayPal DoDirectPayment API operations. Copy the API credentials (Username<\/b>, Password<\/b>, and Signature<\/b>) for later use in the script.<\/p>\n
Before getting started to implement PayPal Pro payment gateway in PHP<\/b>, take a look at the files structure.<\/p>\npaypal_pro_integration_php\/<\/span>\r\n\u251c\u2500\u2500 config.php\r\n\u251c\u2500\u2500 dbConnect.php\r\n\u251c\u2500\u2500 index.php\r\n\u251c\u2500\u2500 payment_process.php\r\n\u251c\u2500\u2500 PaypalPro.class.php\r\n\u251c\u2500\u2500 js\/<\/span>\r\n\u2502 \u251c\u2500\u2500 jquery.min.js\r\n\u2502 \u2514\u2500\u2500 creditCardValidator.js\r\n\u2514\u2500\u2500 css\/<\/span>\r\n \u2514\u2500\u2500 style.css\r\n<\/pre>\nCreate Database Table<\/h2>\n
To store the transaction details, a table is required in the database. The following SQL creates a transactions<\/code> table with some basic fields in the MySQL database.<\/p>\nCREATE<\/span> TABLE<\/span> `transactions`<\/span> (\r\n `id`<\/span> int<\/span>(11<\/span>) NOT<\/span> NULL<\/span> AUTO_INCREMENT,\r\n `item_number`<\/span> varchar<\/span>(50<\/span>) COLLATE<\/span> utf8_unicode_ci NOT<\/span> NULL<\/span>,\r\n `item_name`<\/span> varchar<\/span>(255<\/span>) COLLATE<\/span> utf8_unicode_ci NOT<\/span> NULL<\/span>,\r\n `item_price`<\/span> float<\/span>(10<\/span>,2<\/span>) NOT<\/span> NULL<\/span>,\r\n `item_price_currency`<\/span> varchar<\/span>(10<\/span>) COLLATE<\/span> utf8_unicode_ci NOT<\/span> NULL<\/span> DEFAULT<\/span> 'usd'<\/span>,\r\n `buyer_name`<\/span> varchar<\/span>(50<\/span>) COLLATE<\/span> utf8_unicode_ci NOT<\/span> NULL<\/span>,\r\n `buyer_email`<\/span> varchar<\/span>(50<\/span>) COLLATE<\/span> utf8_unicode_ci DEFAULT<\/span> NULL<\/span>,\r\n `card_num`<\/span> bigint<\/span>(20<\/span>) NOT<\/span> NULL<\/span>,\r\n `card_exp_month`<\/span> varchar<\/span>(2<\/span>) COLLATE<\/span> utf8_unicode_ci NOT<\/span> NULL<\/span>,\r\n `card_exp_year`<\/span> varchar<\/span>(5<\/span>) COLLATE<\/span> utf8_unicode_ci NOT<\/span> NULL<\/span>,\r\n `paid_amount`<\/span> varchar<\/span>(10<\/span>) COLLATE<\/span> utf8_unicode_ci NOT<\/span> NULL<\/span>,\r\n `paid_amount_currency`<\/span> varchar<\/span>(10<\/span>) COLLATE<\/span> utf8_unicode_ci NOT<\/span> NULL<\/span>,\r\n `txn_id`<\/span> varchar<\/span>(50<\/span>) COLLATE<\/span> utf8_unicode_ci NOT<\/span> NULL<\/span>,\r\n `payment_status`<\/span> varchar<\/span>(25<\/span>) COLLATE<\/span> utf8_unicode_ci NOT<\/span> NULL<\/span>,\r\n `created`<\/span> datetime NOT<\/span> NULL<\/span> DEFAULT<\/span> current_timestamp<\/span>(),\r\n `modified`<\/span> datetime NOT<\/span> NULL<\/span> DEFAULT<\/span> current_timestamp<\/span>(),\r\n PRIMARY KEY<\/span> (`id`<\/span>)\r\n) ENGINE<\/span>=InnoDB<\/span> DEFAULT<\/span> CHARSET<\/span>=utf8 COLLATE<\/span>=utf8_unicode_ci;<\/pre>\nPaypalPro Library (PaypalPro.class.php)<\/h2>\n
