File upload using curl. What to do when name of input field is in form of array?

[fireflywins]

Hi,

 

This is the code I made to show the problem:

$useragent = "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.12) Gecko/20101026 Firefox/3.6.12 ( .NET CLR 3.5.30729)";
$timeout = 10 ;
$cookie = tempnam ("/tmp", "CURLCOOKIE");

$post = array('_method'=>"put",
                     'authenticity_token'=>'
zcvcxfsdfvxcv',
                     'profile_image[a]'=>"@Girl-Next-Door-movie-f01.jpg"
                    );
       
        $ch = curl_init();
        curl_setopt( $ch, CURLOPT_USERAGENT, $useragent);
        curl_setopt($ch, CURLOPT_HEADER, 1);
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_HTTPHEADER, array('Expect:'));
        curl_setopt($ch, CURLOPT_URL, "http://localhost/test.php");
        curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie);
        curl_setopt( $ch, CURLOPT_COOKIEJAR, $cookie );
        curl_setopt( $ch, CURLOPT_FOLLOWLOCATION, true );
        curl_setopt( $ch, CURLOPT_ENCODING, "" );
        curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
        curl_setopt( $ch, CURLOPT_AUTOREFERER, true );
        curl_setopt( $ch, CURLOPT_SSL_VERIFYPEER, false );    # required for https urls
        curl_setopt( $ch, CURLOPT_CONNECTTIMEOUT, $timeout );
        curl_setopt( $ch, CURLOPT_TIMEOUT, $timeout );
        curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
        $html = curl_exec($ch);
        curl_close($ch);

Now this link used above: http://localhost/test.php has this code:

    print_r($_POST);
    print_r($_FILES);

It simply prints whats in post and files.

 

 

So the above code displays this on screen:

 

Array
(
    [_method] => put

    [authenticity_token] => zcvcxfsdfvxcv
)
Array
(
    [profile_image] => Array
        (
            [name] => Array
                (
                    [a] => Girl-Next-Door-movie-f01.jpg
                )

            [type] => Array
                (
                    [a] => image/jpeg
                )

            [tmp_name] => Array
                (
                    [a] => /tmp/phppLJPQV
                )

            [error] => Array
                (
                    [a] => 0
                )

            [size] => Array
                (
                    [a] => 55377

                )
        )

)

 

but we need to modify the code so that it should display this:

 

Array
(
    [_method] => put
    [authenticity_token] => zcvcxfsdfvxcv
)
Array
(
    [profile_image[a]] => Array
        (
            [name] => Girl-Next-Door-movie-f01.jpg
              
            [type] => image/jpeg
                
            [tmp_name] =>  /tmp/phppLJPQV

            [error] =>  0
                
            [size] =>  55377
                
        )

)

 

 

Meaning, it is taking this(profile_image[a]) as an array when we are defining $post because that's how curl recognizes that we want to upload only a file or an array of files on server by http post.

 

So, basically the problem is the name of the input field that is defined as an array (profile_image[a]) on the web page that we are trying to mock. If this(profile_image[a]) was this (profile_image_a)(without []) on that webpage, then it would not have been a problem. So, if you understand, this is basically a syntax problem. I do not know how stop curl from reading 'profile_image[a]' as an array here 'profile_image[a]'=>"@Girl-Next-Door-movie-f01.jpg. I need curl to read 'profile_image[a]' as an string and not array. I have to use [], otherwise I will not be able to mock the webpage as the name will change. It will give error.

 

 

I hope I explained the problem and also gave you a way to test if you have a solution. Again, if your code starts displaying this:

 

Array
(
    [_method] => put
    [authenticity_token] => zcvcxfsdfvxcv

)
Array
(
    [profile_image[a]] => Array

        (
            [name] => Girl-Next-Door-movie-f01.jpg     

            [type] => image/jpeg

            [tmp_name] =>  /tmp/phppLJPQV

            [error] =>  0
  
            [size] =>  55377
        )

)

 

,then we have a solution.

 

Thanks for helping in advance.
