PHP Execute a HTTP POST Using PHP CURL

PHP Execute a HTTP POST Using PHP CURL

Today Discussed PHP Curl Post Means PHP Execute a HTTP POST Using PHP Curl.Well, there's a hurdle -- the information isn't going to be saved on the localhost database -- it needs to be stored in a remote database that I cannot connect directly to.

PHP Execute a HTTP POST Using PHP CURL
PHP Execute a HTTP POST Using PHP CURL

  1. User will submit the form, as usual.
  2. In the form processing PHP, I use cURL to execute a POST transmission to a PHP script on the customer's server.
  3. The remote script would do a MySQL INSERT query into the customer's private database.
This solution worked quite well so I thought I'd share it with you. Here's how you execute a POST using the PHP CURL library.


Curl Post Code Follows

//extract data from the post
//set POST variables
$url = 'http://domain.com/get-post.php';
$fields = array(
 'lname' => urlencode($_POST['last_name']),
 'fname' => urlencode($_POST['first_name']),
 'title' => urlencode($_POST['title']),
 
);

//url-ify the data for the POST
foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; }
rtrim($fields_string, '&');

//open connection
$ch = curl_init();

//set the url, number of POST vars, POST data
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_POST, count($fields));
curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string);

//execute post
$result = curl_exec($ch);

//close connection
curl_close($ch);

PAYPAL INTEGRATION WITH PHP & MYSQL


Paypal Integration
Paypal Integration
Previously Discussed Simple PHP shopping cart stored a cart payment integration is discussed Follow us
Simple Way to PHP Paypal Integration following steps.

Step : 1

First Setup your Paypal Account

Signup Paypal Account if you don't already have one.  In order to use PIN, the paypal account you are selling from must be a Business Account

Select ‘edit profile’ from your PayPal account and check the following settings.

Under ‘My Selling Preferences’ >> ‘Getting paid and managing risk’ >> ‘Instant Payment Notification Preferences’
  1. Set the IPN value to ‘On’
  2. Set the IPN URL to the PHP page containing the IPN code shown in steps 3 & 4 of this tutorial. (http://www.example.com/payment.php)
Step : 2

Your Website Looking UI design and must now send all required value to paypal so that the payment can be processed.
