The document discusses various ways to upload and display documents from SlideShare using their API. It provides steps to get API keys from SlideShare and create a PHP form to upload documents. It also describes methods to retrieve uploaded documents through the API and display them on a website, including using XML responses, oEmbed API calls, and JavaScript player embedding.

1. Upload and show documents from slideshare on our application using API in PHP
Before start using apis of slideshare , we need to have authentication api for it
Steps for getting API key and secret key for your application:
1. After Login: go to http://www.slideshare.net/developers/applyforapi and enter your name
and send request for api
2. API key along with secret key will be mail to your mail soon after the request
Note : This method requires extra permissions. If you want to upload a file using SlideShare API, please send an
email to api@slideshare.com with your developer account username describing the use case.

Response XML Format
<SlideShowUploaded>

2. <SlideShowID>{slideshow id goes here}</SlideShowID>
</SlideShowUploaded>
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

3. view on our application
2. Viewing the document in slideshare layout :
Multiple ways to do that but depend upon the input we have
Currently we have only slideshowID for doc so using api through curl we will fetch the data and
display the embed code.
First Method :
<?php
class 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
<?php
include_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

4. echo $movies­>PPTLocation; ­­­­­­­­­­­­­­­­­­­­­1
­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­
Second Method :
if you have url of slide share, you can call oembed api thru curl
eg: http://www.slideshare.net/api/oembed/2?url={url}&format=json
­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­
Third 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;?>

5. //Update the slide number in the field for the same
