Se stai gestendo un sito Web, riscuotendo un pagamento online, probabilmente hai sentito parlare dello Stripe Payment Gateway<\/strong>. Utilizzando Stripe, si pu\u00f2 accettare il pagamento utilizzando una carta di credito o di debito. Questo \u00e8 un modo pi\u00f9 conveniente per pagare online per i tuoi clienti. In questo articolo, studiamo l’integrazione di Stripe nel sito Web con PHP.<\/p>\n

Perch\u00e9 dovresti usare il gateway di pagamento Stripe?<\/h3>\n

Stripe<\/a> \u00e8 uno dei gateway di pagamento pi\u00f9 popolari e sicuri su Internet. I dettagli della carta dell’utente sono sempre al sicuro con i pagamenti Stripe. Infatti, al checkout di Stripe forniscono elementi generati in cui un utente deve inserire i dettagli della carta. Gli elementi per inserire i dettagli della carta sono generati da Stripe in fase di esecuzione, il che rende questo gateway pi\u00f9 sicuro.<\/p>\n

Dopo aver inserito i dettagli della carta, Stripe genera un token che utilizzer\u00e0 per addebitare il pagamento con carta. Di conseguenza, non \u00e8 necessario memorizzare i dettagli della carta.<\/p>\n

Detto questo, diamo un’occhiata all’integrazione di Stripe in un sito Web che utilizza PHP.<\/p>\n

Ottieni chiavi API per l’integrazione con Stripe<\/h3>\n

Per iniziare, dovresti avere un account Stripe<\/a>. Per integrare il gateway Stripe nella tua applicazione, devi ottenere la tua chiave segreta Stripe e la chiave pubblicabile.<\/p>\n

Accedi alla tua dashboard di Stripe. Otterrai quelle chiavi da Developers->API Keys<\/strong>. Ti consiglio di provare prima le transazioni di pagamento con la modalit\u00e0 di prova. Se tutto funziona bene, vai in modalit\u00e0 live. Quindi prendi le chiavi API per la modalit\u00e0 di test.<\/p>\n

\"Una<\/a><\/p>\n

Modulo di pagamento a strisce<\/h3>\n

Ogni volta che integriamo un gateway di pagamento sul sito Web, dobbiamo memorizzare i dettagli della transazione nel database. Quindi creiamo una payments<\/code>tabella utilizzando la query SQL seguente.<\/p>\n

CREATE TABLE `payments` (\u00a0`id` int(11) NOT NULL AUTO_INCREMENT,\n\u00a0`payment_id` varchar(255) NOT NULL,\n\u00a0`amount` float(10,2) NOT NULL,\n\u00a0`currency` varchar(255) NOT NULL,\n\u00a0`payment_status` varchar(255) NOT NULL,\n\u00a0`captured_at` datetime NOT NULL DEFAULT current_timestamp(),\n\u00a0PRIMARY KEY (`id`)) ENGINE=InnoDB DEFAULT CHARSET=latin1;<\/code><\/pre>\n
Quindi, crea un modulo di pagamento. Come ho detto prima, Stripe genera elementi di carte per te. Genereremo questi elementi nel modulo di pagamento seguendo la documentazione di Stripe<\/a>.<\/p>\n
Crea il index.html<\/code>file e inserisci il codice seguente al suo interno.<\/p>\n
<link rel=\"stylesheet\" href=\"style.css\" \/>\n<script src=\"https:\/\/js.stripe.com\/v3\/\"><\/script>\n<form action=\"charge.php\" method=\"post\" id=\"payment-form\">\n\u00a0\u00a0\u00a0\u00a0<div class=\"form-row\">\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<input type=\"text\" name=\"amount\" placeholder=\"Enter Amount\" \/>\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<label for=\"card-element\">\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0Credit or debit card\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<\/label>\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<div id=\"card-element\">\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<!-- A Stripe Element will be inserted here. -->\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<\/div>\n\u00a0\u00a0\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<!-- Used to display form errors. -->\n\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<div id=\"card-errors\" role=\"alert\"><\/div>\n\u00a0\u00a0\u00a0\u00a0<\/div>\n\u00a0\u00a0\u00a0\u00a0<button>Submit Payment<\/button>\n<\/form>\n<script src=\"card.js\"><\/script><\/code><\/pre>\n
Aggiungi uno stile al modulo utilizzando il codice seguente nel style.css<\/code>file.<\/p>\n
.StripeElement {\n\u00a0\u00a0\u00a0\u00a0box-sizing: border-box;\n\u00a0\u00a0\u00a0\u00a0\n\u00a0\u00a0\u00a0\u00a0height: 40px;\n\u00a0\u00a0\u00a0\u00a0\n\u00a0\u00a0\u00a0\u00a0padding: 10px 12px;\n\u00a0\u00a0\u00a0\u00a0\n\u00a0\u00a0\u00a0\u00a0border: 1px solid transparent;\n\u00a0\u00a0\u00a0\u00a0border-radius: 4px;\n\u00a0\u00a0\u00a0\u00a0background-color: white;\n\u00a0\u00a0\u00a0\u00a0\n\u00a0\u00a0\u00a0\u00a0box-shadow: 0 1px 3px 0 #e6ebf1;\n\u00a0\u00a0\u00a0\u00a0-webkit-transition: box-shadow 150ms ease;\n\u00a0\u00a0\u00a0\u00a0transition: box-shadow 150ms ease;\n}\n\u00a0\u00a0\n.StripeElement--focus {\n\u00a0\u00a0\u00a0\u00a0box-shadow: 0 1px 3px 0 #cfd7df;\n}\n\u00a0\u00a0\n.StripeElement--invalid {\n\u00a0\u00a0\u00a0\u00a0border-color: #fa755a;\n}\n\u00a0\u00a0\n.StripeElement--webkit-autofill {\n\u00a0\u00a0\u00a0\u00a0background-color: #fefde5 !important;\n}<\/code><\/pre>\n
Successivamente, per generare l’elemento card e lo stripeToken \u00e8 necessario aggiungere il seguente codice JavaScript nel card.js<\/code>file. Questo codice JavaScript convalida anche i dettagli della carta.<\/p>\n

Devi sostituire il segnaposto PUBLISHABLE_KEY con la tua chiave effettiva nel codice sopra.<\/p>\n
Ho aggiunto uno stile casuale al modulo. Puoi modificare il design del modulo per adattarlo al tuo sito web. Inoltre, Stripe offre diversi design degli elementi delle carte. Maggiori informazioni sulla documentazione<\/a>.<\/p>\n
Quando l’utente invia un modulo con i dettagli della carta, Stripe genera un token in background che verr\u00e0 impostato come "token" di campo nascosto. Questo token verr\u00e0 utilizzato per addebitare un pagamento con carta utilizzando Stripe SDK.<\/p>\n
Stiamo inviando i dati del modulo al file charge.php<\/code>. In questo file PHP, addebiteremo la carta ed eseguiremo il pagamento.<\/p>\n
Integrazione Stripe con Omnipay in PHP<\/h3>\n
Abbiamo impostato tutto con la configurazione di base. Ora, per addebitare il pagamento con carta, installa la libreria Omnipay Stripe<\/a>. Apri il terminale nella directory principale del tuo progetto ed esegui il comando seguente:<\/p>\n
composer require league\/omnipay omnipay\/stripe<\/code><\/pre>\n
Al momento dell’installazione della libreria, creare un file config.php e inizializzare l’oggetto di pagamento e la connessione al database.<\/p>\n
<?php\nrequire_once \"vendor\/autoload.php\";\n\u00a0\u00a0\nuse OmnipayOmnipay;\n\u00a0\u00a0\u00a0\n\/\/ Connect with the database \n$db = new mysqli('MYSQL_HOST', 'MYSQL_DB_USERNAME', 'MYSQL_DB_PASSWORD', 'MYSQL_DB_NAME');\n\u00a0\u00a0\u00a0\u00a0\nif ($db->connect_errno) {\n\u00a0\u00a0\u00a0\u00a0die(\"Connect failed: \". $db->connect_error);\n}\n\u00a0\u00a0\u00a0\n$gateway = Omnipay::create('Stripe');\n$gateway->setApiKey('SECRET_KEY_HERE');<\/code><\/pre>\n
Assicurati di sostituire tutti i segnaposto con i valori effettivi. Successivamente, nel tuo charge.php<\/code>scrivere il codice come segue.<\/p>\n

Abbiamo finito con la parte di codifica. Vai avanti e prova i pagamenti sandbox. Stripe fornisce i dettagli della carta fittizia<\/a> per testare il pagamento.<\/p>\n
Ogni volta che hai deciso di andare in diretta, devi solo cambiare la tua chiave segreta e pubblicabile con le credenziali live.<\/p>\n
Spero che tu possa conoscere l’integrazione di Stripe su un sito Web con PHP. Mi piacerebbe sentire i tuoi pensieri e suggerimenti nella sezione commenti qui sotto.<\/p>\n
