Create following form : //do not change the form action as it api url for uploading<form action="https://www.slideshare.net/api/2/upload_slideshow" method="post" enctype='multipart/form­data'name="ssuploadform">Slideshare API Key (api_key):<br/><input name="api_key" type="text" size="20"><br><br>Slideshare Shared Secret:<br/><input name="sharedsecret" type="text" size="20"><br><br><input name="ts" type="hidden" value=""><input type="hidden" name="hash" value="">Slideshare username (username): <br><input name="username" type="text" value="" size="20"><br><br>Slideshare password (password): <br><input name="password" type="text" value="" size="20"><br><br>Slideshow Title (slideshow_title): <br><input name="slideshow_title" type="text" value="My cool new Slideshow!"size="50"><br><br>Slideshow Source File (slideshow_srcfile): <br><input name="slideshow_srcfile" type="file" size="20"><br><br><input type="submit" onClick="return generateTimeHash(this.form)" value="Upload Slideshow!"></form>

<script type="text/javascript">function getUnixTime()

var theDate = new Date();return Math.round(theDate.getTime()/1000.0);

function generateTimeHash(form)

if (form != null) var timestr = getUnixTime();var ss = document.ssuploadform.sharedsecret.value;form.ts.value = timestr;var hashstr = SHA1(ss + timestr);alert('UNIX Time=[' + timestr + ']\nSecret Key=[' + ss + ']\nSHA1 Hash=[' + hashstr + ']');form.hash.value = hashstr;return true;

return false;

</script>

FIll this form and you will be able to upload the doc to slideshare

In resonse you will get the slideshowID in xml, store it and save it in db for fetching same doc for

view on our application

2. Viewing the document in slideshare layout :Multiple ways to do that but depend upon the input we haveCurrently we have only slideshowID for doc so using api through curl we will fetch the data anddisplay the embed code.First Method :<?phpclass slideShare //*** do not alter this­­­­ public $endpoint = 'https://www.slideshare.net/api/2/'; public $key = 'XXXXXX'; //your api key public $secret = 'XXXXXX'; //your secret key //­­­­­*** public function call($api,$params) $ts = time(); $hash = sha1($this­>secret . $ts); $url = $this­>endpoint . $api."api_key=$this­>key&ts=$ts&hash=$hash&" . $params; return $this­>curlRequest($url); public function curlRequest($url) $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); $res = curl_exec($ch); curl_close($ch); return $res;

­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­view page : index.php

<?phpinclude_once 'slide_share.php';

$req=new slideShare();$id=25835769; // just example$show=$req­>call("get_slideshow?","slideshow_id=$id&exclude_tags=1&detailed=1");

//print_r($show);$movies = new SimpleXMLElement($show);echo $movies­>ID;echo $movies­>Embed; // this returns the object of your document

echo $movies­>PPTLocation; ­­­­­­­­­­­­­­­­­­­­­1­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­

Second Method :if you have url of slide share, you can call oembed api thru curleg: http://www.slideshare.net/api/oembed/2?url=url&format=json­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­Third Method :

Javascript:After getting PPTLocation from first method [1] XML ,we can also use its javascript api

From first method point 1­­­­­­­­<?php $doc=$movies­>PPTLocation;?><html> <head> <title>SlideShare Player API Example</title> <script type="text/javascript" src="swfobject.js"></script> <script type="text/javascript"> var flashMovie;

//Load the flash player. Properties for the player can be changed here. function loadPlayer() //allowScriptAccess from other domains var params = allowScriptAccess: "always" ; var atts = id: "player" ;

//doc: The path of the file to be used //startSlide: The number of the slide to start from //rel: Whether to show a screen with related slideshows at the end or not. 0 means false and 1 istrue.. var flashvars = doc : "thirst­upload­800x600­1215534320518707­8",//<?php echo $doc?> startSlide : 1, rel : 0 ;

//Generate the embed SWF file swfobject.embedSWF("http://static.slidesharecdn.com/swf/ssplayer2.swf", "player", "598", "480","8", null, flashvars, params, atts);

//Get a reference to the player flashMovie = document.getElementById("player");

//Jump to the appropriate slide function jumpTo() flashMovie.jumpTo(parseInt(document.getElementById("slidenumber").value));

//Update the slide number in the field for the same function updateSlideNumber() document.getElementById("slidenumber").value = flashMovie.getCurrentSlide(); </script> </head> <body bgcolor="#ffffff" onload="loadPlayer();"> <?php ?> <div id="player"> You need Flash player 8+ and JavaScript enabled to view this video. </div> <div style="margin­left: 150px; margin­top: 10px;"> <button onclick="flashMovie.first();updateSlideNumber();" type="button" value="First">First</button> <button onclick="flashMovie.previous();updateSlideNumber();" type="button"value="Previous">Previous</button> <button onclick="jumpTo();updateSlideNumber();" type="button" value="Go to">Go to</button> <input type="text" id="slidenumber" size="2" value="1" onkeydown="if (event.keyCode == 13) jumpTo(); "/> <button onclick="flashMovie.next();updateSlideNumber();" type="button" value="Next">Next</button> <button onclick="flashMovie.last();updateSlideNumber();" type="button" value="Last">Last</button> </div> </body></html>
