Web Service using JSONP from External Domain – PHP – JQuery

dan — Fri, 03 Feb 2012 15:57:31 +0000

You may want to look at this previous post where I setup a PHP Webservice that uses JSON PDO – Accessed by JQuery AJAX

OK, so this code will use php to generate the JSON code that will get delivered over the internet to the JSONP (JSON Padding) client on an external domain. This allows your webservice to be available too whoever wants to call it.

Here is the PHP Code: (Not all of it, but enough to get the idea)

//http://SERVER_domain.com/webservice.php
private function GetTriviaTag($row) {
	$t = new Tag();
	$t->id = $row['id'];
	$t->triviaid = $row['triviaid'];
	$t->tagid = $row['tagid'];
	return $t;
}
public function GetWhere($where) {
	$retArray;
 
	$sql = "SELECT * FROM trivia_tags WHERE {$where}";
	foreach ($this->pdo->query($sql) as $row)
	{
		$retArray[] = $this->GetTriviaTag($row);
	}
	return $retArray;
}
$where = " (1 = 1)";  // THIS WILL SELECT ALL
$tarray = GetWhere($where);
 
//OUTPUT JSON:
header('Content-type: application/json');
echo $_GET['callback'];  // <-- THIS IS IMPORTANT FOR EXTERNAL DOMAIN ACCESS!!!
echo "(" . json_encode($tarray) . ")";

And now, to access it from javascript in an external domain (non – SERVER_domain.com ):

http://CLIENT_domain.com/Test.html:

<html>
	<head>
		<title>Testtitle>
		<script src="http://code.jquery.com/jquery-latest.js">script>
	head>
	<body>
		<div id="triviaQuestions"> loading... div>
		<script>
			$(function() {
				// THE 'callback=?' in this request is IMPORTANT FOR EXTERNAL DOMAIN ACCESS!!!
				$.getJSON('http://SERVER_domain.com/webservice.php&callback=?', function(data) {
					var items = [];
					var htmlResult = "";
					$.each(data, function(key, val) {
						htmlResult += "
Q: "+ val.id +", '"+ val.question +"";
					});
					$('#triviaQuestions').html(htmlResult);
				});
			});
		
	body>
html>

PHP Webservice that uses JSON PDO – Accessed by JQuery AJAX

dan — Fri, 06 Jan 2012 15:25:58 +0000

You may want to look at this previous post where I setup a Web Service using JSONP from External Domain – PHP – JQuery

The HTML that calls the Javascript:

<div id="taglist"></div>
<input name="searchTags" id="searchTags" type="text" />
<input type="button" name="searchtags" onclick="getTags()" value="search"/>
<div id="tagresult">
</div>

The JavaScript (JQuery) AJAX Request and Response Processing:

function getTags()
	{
		var q = $('#searchTags').val();
		$.getJSON('ws.php?type=tag&wN=name&wO=like&wV=' + q, function(data) {
			var items = [];
			var htmlResult = "";
			$.each(data, function(key, val) {
				//As you can see, you can access the JSON (at the bottom of the page) by doing val.PROPERTYNAME:
				htmlResult += "
Add : \"#\" onclick=\"addTag("+ val.id +", '"+ val.getfullname +"'); return false;\">"+ val.getfullname +"";
			});
			$('#tagresult').html(htmlResult);
		});
	}

PHP Code that returns JSON in the PHP file called by the AJAX: (ws.php)

	$ta = new TagAccess();
	$tarray = $ta->GetTagsWhere(" {$whereName} LIKE '%{$whereVariable}%'");
	header('Content-type: application/json');
	echo "",  json_encode($tarray), "";

The GetTagsWhere Helper Function:

    public function GetTagsWhere($where) {
    	$retArray;
 
    	$sql = "SELECT * FROM tags WHERE {$where}";
    	// THE PDO Object was created previously
	foreach ($this->pdo->query($sql) as $row)
	{
		$retArray[] = $this->GetTag($row);
	}
	return $retArray;
    }

JSON Returned:

[{"id":"4","name":"FICTION","parentid":"3","getfullname":"BOOKS > FICTION"},{"id":"5","name":"NON-FICTION","parentid":"3","getfullname":"BOOKS > NON-FICTION"}]

Simple PHP Pseudo Proxy

dan — Wed, 06 Jul 2011 11:51:56 +0000

This is the code for a simple php pseudo proxy. If you are blocked by a firewall and google cache isn’t working for some reason. You can use a url with this php file in it:


$filename = $_GET["url"];
if (isset($filename))
{
        $handle = fopen($filename, "rb");
        $contents = stream_get_contents($handle);
        print $contents;
        fclose($handle);
}
else
{
        echo "url";
?>




}
?>

Then you can go to where the url is hosted and try something like this:

index.php?url=http%3A%2F%2Fwww.last.fm%2Fuser%2Fdanfolkes%2Fcharts%3Frangetype%3D6month%26subtype%3Dartists

Facebook Website Integration – HTML

dan — Wed, 25 May 2011 15:40:03 +0000

To integrate Facebook on to a website without the use of a facebook app you need these things:

Facebook Page RSS Feed (can be tricky)
Feedburner Account (free,easy) (here)

Once you have both of those things you can do this in feedburner:

Add a new feed (your facebook url)
Go to the publicize tab
Go to BuzzBoost
Sroll down and fill out the form, you will be given html code.

Preview:

And that’s it!
You can now style it up a little bit with some CSS and stuff.

PHP API – Google Calendar – Updating Visibility

Pitchfork 'Best New Albums' Torrent Search

dan — Tue, 21 Sep 2010 16:41:43 +0000

Ok so this might be slightly illegal, but I am really just generating some links.

I wrote some code that will take the RSS feed from this page: http://pitchfork.com/reviews/best/albums/ and searches BTJunkie for torrents.

Here it is in action:
http://danfolkes.com/pitchfork_torrent_albums_best/

Here is the source: (also here)


  echo "";$doc=new DOMDocument();$doc->load('http://feeds2.feedburner.com/PitchforkBestNewAlbums');
 
  foreach($doc->getElementsByTagName('item')as$node){echo"";foreach($doc2->getElementsByTagName('item')as$node2){echo"";}
 
  }//print_r($arrFeeds);echo"
    
      
	 ";
	$title = $node->getElementsByTagName('title')->item(0)->nodeValue;
	echo $title;
    $doc2 = new DOMDocument();
 	$doc2->load("http://btjunkie.org/rss.xml?query=".urlencode($title));
	echo "
	    
		 ";
		$link = ")->item(0)->nodeValue."' target='_blank'>";
		$link.= $node2->getElementsByTagName('title')->item(0)->nodeValue."";
		echo $link;

PHP Base64_Encode – Intentionally screwing up pictures

dan — Wed, 15 Sep 2010 20:48:18 +0000

A screwed up base64 image. Replaced all of the 'da' with 'ha'

So, I was a little bored so I made some PHP code.

This is what it does:

Takes query string values
Pulls an image from the web
base64_encodes it.
Distorts the image.
Replaces some of the base64 string data with other string data.
Outputs the image in an img tag.

Hope this helps someone, let me know if it does IN THE COMMENTS


	if ((isset($_GET['i']))&&(isset($_GET['f']))&&(isset($_GET['r'])))
	{
		$find = $_GET['f'];
		$replace = $_GET['r'];
		$type = "gif";
		print_r($_GET);
 
		if (isset($_GET['t']))
		{
			$type = $_GET['t'];
		}
		$imgfile = $_GET['i'];
		$contents = implode (file($imgfile));
		$start = base64_encode($contents);
 
 
		$start = str_ireplace($find, $replace, $start);
 
	echo '.$type.';base64,' . $start . '" />';
	}
	else
	{
	?>

PHP Gmail Imap Connection with Database Insert

dan — Wed, 31 Mar 2010 16:15:02 +0000

Using PHP, We will connect to a Gmail mailbox and pull down the last message headers and to and from email addresses.
With this data, we will insert it into a MySQL Database and then delete the message from the IMAP Server.

LET ME KNOW IF THIS HELPED YOU IN THE COMMENTS! Enjoy!

Here is the code:


	$dbhost = 'localhost';
	$dbuser = 'DATABASE_USER';
	$dbpass = 'DATABASE_PASSWORD';
	$dbname = 'DATABASE_NAME';
 
	$imapserverstring = 'imap.gmail.com:993/imap/ssl/novalidate-cert';
	$imapuser = 'GOOGLE_USERNAME@gmail.com';
	$imappass = 'GOOGLE_PASSWORD';
 
 
	$mbox = imap_open("{".$imapserverstring."}INBOX", $imapuser,$imappass)	or die("can't connect: " . imap_last_error());
 
	$check = imap_mailboxmsginfo($mbox);
 
	if ($check) {
		echo "Date: "     . $check->Date    . "
\n" ;
		echo "Driver: "   . $check->Driver  . "
\n" ;
		echo "Mailbox: "  . $check->Mailbox . "
\n" ;
		echo "Messages: " . $check->Nmsgs   . "
\n" ;
		echo "Recent: "   . $check->Recent  . "
\n" ;
		echo "Unread: "   . $check->Unread  . "
\n" ;
		echo "Deleted: "  . $check->Deleted . "
\n" ;
		echo "Size: "     . $check->Size    . "
\n" ;
	} else {
		echo "imap_check() failed: " . imap_last_error() . "
\n";
	}
 
	echo "Headers in INBOX
\n";
	$headers = imap_headers($mbox);
 
	if ($headers == false) {
		echo "Call failed (or no messages)
\n";
	} else {
		foreach ($headers as $val) {
			echo $val . "
\n";
		}
	}
	$FirstMessageArray = implode('', array(imap_fetchbody($mbox, 1, "")));
	echo $FirstMessageArray;
	$subject = "";
	$message = "";
	$to = substr  ( $FirstMessageArray ,  0,  10 );
	$from = "";
 
 
 
	$conn = mysql_connect($dbhost, $dbuser, $dbpass) or die ('Error connecting to mysql');
	mysql_select_db($dbname);
	$query  = "INSERT INTO `DatabaseTable` (`id`, `to`, `from`, `subject`, `message`) VALUES (NULL, '{$to}', '{$from}', '{$subject}', '{$message}');";
	$result = mysql_query($query);
	mysql_close($conn);

CWS – Chord Web Service

dan — Tue, 31 Mar 2009 19:56:20 +0000

I am creating a web service for musicians that will allow them to reference an abundance of musical references on the fly using AJAX.

Firstly, it will deliver chords and fingerings of chords for guitars to the users websites (think Google Maps).

My goal is to enhance the web.

Here is the site: http://cws.danfolkes.com

It’s still in development, but it’s getting close to launch.

Let me know what you think (only if it’s nice)
