Upload images to Imageshack using cURL

Recommended Posts

I am trying to upload images to Imageshack directly form my site with Imageshack API, using the code bellow:

 

index.htm

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"

    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

 

<html xmlns="http://www.w3.org/1999/xhtml">

 

<head>

  <title></title>

</head>

<body>

    <form action="curl-form.php" method="post" enctype='multipart/form-data'>

        <input type="file" id="foto" name="foto" />

        <input type="submit" value="Enviar" />

    </form>

</body>

</html>

 

img.php

<?php

$data = array();

$data['fileupload'] = '@' . $_FILES["foto"]['tmp_name'];

$data['key']        = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx';

$data['email']      = 'email@email.com';

$data['rembar']    = 'yes';

$data['optsize']    = '96x96';

$data['xml']        = 'yes';

 

$post_str = '';

foreach($data as $key=>$val) {

$post_str .= $key.'='.urlencode($val).'&';

}

$post_str = substr($post_str, 0, -1);

 

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, 'http://www.imageshack.us/upload_api.php');

curl_setopt($ch, CURLOPT_POST, TRUE);

curl_setopt($ch, CURLOPT_HEADER, FALSE);

curl_setopt($ch, CURLOPT_TIMEOUT, 240);

curl_setopt($ch, CURLOPT_POSTFIELDS, $post_str);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);

$response = curl_exec($ch );

curl_close($ch );

 

if (strpos ( $response, '<' . '?xml version="1.0" encoding="iso-8859-1"?>' ) === false)

{

    return NULL;

}

else

{

    $xml = new SimpleXMLElement ( $response );

    return array (

    "image" => $xml->image_link,

    "thumb" => $xml->thumb_link );

}

?>

 

When I upload an image, the following error occurs:

 

"Sorry, but we've detected that unexpected data is received. Required parameter 'fileupload' is missing or your post is not multipart/form-data"

 

What is wrong with the code?

How can I send enctype='multipart/form-data' with cURL?

I tried using different code:

<?php

$postData = array();

$postData['fileupload'] = "@" . $_FILES['foto']['tmp_name'];

$postData['submit']    = "Submit";

$postData['key']        = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";

$postData['email']      = "email@email.com";

$postData['rembar']    = "yes";

$postData['optsize']    = "96x96";

$postData['xml']        = "yes";

 

$ch = curl_init();

 

curl_setopt($ch, CURLOPT_URL, "http://www.imageshack.us/upload_api.php");

curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);

curl_setopt($ch, CURLOPT_POST, 1 );

curl_setopt($ch, CURLOPT_POSTFIELDS, $postData );

 

$response = curl_exec( $ch );

curl_close($ch );

 

echo $response . "<br />";

?>

 

and the different error message was sent:

Wrong file type detected for file php6JrCec:application/octet-stream

cURL  sent file using their temp name and the type verification of the Imageshack was refused.

How can I send files to Imageshack using cURL?

I found a solution. I don´t know if this is the better solution, but works fine.

 

index.htm

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"    
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>  
<title></title>
</head>
<body>    
<form action="imagem.php" method="post" enctype='multipart/form-data'>        
<input type="file" id="foto" name="foto" />        
<input type="submit" value="Enviar" />    
</form>
</body>
</html>

 

imagem.php

<?php
preg_match("/\.(gif|bmp|png|jpg|jpeg){1}$/i", $_FILES['foto']['name'], $ext);
$imagem_nome = md5(uniqid(time())) . "." . $ext[1];
rename($_FILES['foto']['tmp_name'], "/tmp/" . $imagem_nome);

$postData = array();
$postData['fileupload'] = "@/tmp/" . $imagem_nome;
$postData['submit']     = "Submit";
$postData['key']         = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
$postData['rembar']     = "yes";
$postData['xml']        = "yes";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://www.imageshack.us/index.php");
curl_setopt($ch, CURLOPT_POST, true );
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch, CURLOPT_TIMEOUT, 240);curl_setopt($ch, CURLOPT_POSTFIELDS, $postData );

$response = curl_exec( $ch );
curl_close($ch );

echo $response;
?>

 

I did not use the $_FILES['foto']['type'] function to get the file extension, because if the file type is jpg, this function returns pjpg, generating an error of invalid format in the Imageshack.

The Imageshack then returns a xml that be parsed, with links to the image.

 

I have another question. When I renamed the file in the temp directory, this file will be automatic deleted or I need to delete the file manually?
