Slider-PRO-WordPress-Premium-Slider-Plugin

Image/Content Sliders are meant to improve the interactivity and accessibility of a website, being used in portfolio pages, news websites, blogs to feature posts, small presentations etc. Not only they make your site user-friendly but they can also feature content in a small space. Years ago, Flash used to be the most popular choice to make Image Slideshows because of its animation capability. Things changed and JavaScript Sliders have taken over the territory helping you to feature the content in an eye-candy way without worrying the visitor does not have Flash enabled, especially the mobile users.

Send HTTP POST Data to Remote URL

Posted on April 25, 2013, under PHP,  Bookmark it

Hi guys,

I’d like to share with you a function that I use a lot in my web projects. It’s useful to send data through POST from one location to another. It’s very useful if you need to send information from a server to a remote one. For example, you can use AJAX to call a PHP file from your website that when being accessed, it will send POST data to a Remote URL location and get its output, all of this being processed in the background.

/**
 * SendPostData()
 * 
 * @param mixed $_p
 * @param mixed $remote_url
 * @return
 */
function SendPostData($_p, $remote_url) {
	$remote_url = trim($remote_url);

	$is_https = (substr($remote_url, 0, 5) == 'https');

	$fields_string = http_build_query($_p);

	// Run this code if you have cURL enabled
	if(function_exists('curl_init')) {
		
		// create a new cURL resource
		$ch = curl_init();
		
		// set URL and other appropriate options
		curl_setopt($ch, CURLOPT_URL, $remote_url);
		
		if($is_https && extension_loaded('openssl')) {
			curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
			curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
		}
		
		curl_setopt($ch, CURLOPT_POST, 1);
		curl_setopt($ch, CURLOPT_POSTFIELDS, $fields_string);            
		curl_setopt($ch, CURLOPT_HEADER, false);

		curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
		
		// grab URL and pass it to the browser
		$response = curl_exec($ch);
					
		// close cURL resource, and free up system resources
		curl_close($ch);

	// No cURL? Use an alternative code   
	} else {
		
		$context_options = array (
			'http' => array (
				'method' => 'POST',
				'header' => "Content-type: application/x-www-form-urlencoded\r\n".
							"Content-Length: ".strlen($fields_string)."\r\n",
				'content' => $fields_string
			 )
		 );

		$context = stream_context_create($context_options);
		$fp = fopen($remote_url, 'r', false, $context);

		if (!$fp) {
			throw new Exception("Problem with $remote_url, $php_errormsg");
		}

		$response = @stream_get_contents($fp);

		if ($response === false) {
			throw new Exception("Problem reading data from $remote_url, $php_errormsg");
		}
	}
	return $response;
}

Usage Example:

$response = SendPostData($_POST, 'http://www.myserver2location.com/receive-data.php');

PS: You can use any array variable as the first argument. $_POST is just a common one used in these situations.
