Post to external site

[newbtophp]

Im trying to submit and retrieve a file form an external site. Im using file_get_contents , because Im unfamilar of how to do so with cURL.

 

The external site has a form which you upload a file and it echos some content on the same page.

 

This is the html source from the external site:

 

<form enctype="multipart/form-data" method="post" >
<p><input type="hidden" name="MAX_FILE_SIZE" value="2097152" />
<input name="upload" type="file" />
<input type="submit" value="Show" /></p>
</form>

 

This is the bit where the content is echo'd after the upload:

<div id="output">

the echo'd content from the uploaded file is contained within this tag 
on the external site
</div>

 

I managed to grab the form but it dont function, I click a file to upload, but I cant get the file to display on my site.

 

Heres the code:

 

<?php 
    $url = "http://www.externalsite.com";
    $rurl = file_get_contents($url);

           $i = 1; 
           while($i <= 5)
          {
                $start = explode('<form enctype="multipart/form-data" method="post" >', $rurl);
                $end = explode('</form>', $start[$i]);
                $table .= $end[0];
                $i++;
           }            
           echo $table;
                
?>

I just tried to write up a script to do this and ran into two possible road blocks, CURL_PUT doesn't allow you to send a form field name to go along with the file pointer, unless I'm mistaken, and I did some googling and cURL's @filename doesn't exactly work thru php. hope sum1 else can give you a better answer.

I tried:

 

<?php

// Using CURL

//URL
$url = 'http://www.showmycode.com'; //External site

/* Post Data */
$postData['upload'] = 'upload';
$postData['submit'] = 'submit';

$ch = curl_init(); // initialize curl handle
curl_setopt($ch, CURLOPT_URL,$url); // set url to post to
curl_setopt($ch, CURLOPT_FAILONERROR, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);// allow redirects
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); // return into a variable
curl_setopt($ch, CURLOPT_TIMEOUT, 50); // times out after 50s
curl_setopt($ch, CURLOPT_POST, 1); // set POST method
curl_setopt($ch, CURLOPT_POSTFIELDS, $postData); // add POST fields
$buffer = curl_exec($ch); // run the whole process
curl_close($ch);

echo $buffer;
?> 

 

But still no luck, the site where the form is located is:

 

www.showmycode.com

 

On that site the form has no action or no name, so I find it hard to do it with curl, because on that site the output after the upload is echo'd back on the same page.

 

Can you take a look at that site?, and let me know please.

 

Thanks
