sending Curl POSTFIELDS array

Question

I am trying to use CURL to post the following fields to PANDADOCS, but for some reason I am getting an error that the values are not being received on their side.

This is the error I am getting:

"type": "validation_error", "detail": {"url": ["This field is required."], "name": ["This field is required."]}}

I am posting with the following:

$docurl = "myurl.com/document.pdf";
$headr = array();
$headr[] = 'Content-length: 0';
$headr[] = 'Content-Type: application/json;charset=UTF-8';
$headr[] = "Authorization: Bearer $ACCESS_TOKEN";
$url = 'https://api.pandadoc.com/public/v1/documents';
$ch = curl_init();
curl_setopt($ch, CURLOPT_HTTPHEADER,$headr);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, FALSE);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_USERAGENT, $useragent);


$postfields = array();

$postfields['name'] = 'PSA';
$postfields['url'] = $docurl;
$postfields['recipients'] = array ([0]=>array(

            ['email'] => ['dondon@gmail.com'],
            ['first_name'] => ['don'],
            ['last_name'] => ['jones'],
            ['role']=>['u1']    ));



curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query(  $postfields) );
$ret = curl_exec($ch); //

when I print_r($postfields) I get Array ( [name] => PSA [url] => https://api.pandadoc.com/public/v1/documents [recipients] => Array ( ) )

so all the fields arent getting posted.

but whats wierd is that the URL and NAME are in the array but not the other fields yet the error is complaining about not receiving NAME and URL..

dazed and confused...

`$string` is never defined in your posted code. – arkascha Mar 06 '15 at 18:43 — arkascha, Mar 06 '15 at 18:43

$string is not defined.

Add

$string = http_build_query( $postfields );

after

$postfields = array();

$postfields['name'] = 'PSA';
$postfields['url'] = $docurl;

// This is invalid array
$postfields['recipients'] = array ([0]=>array(

        ['email'] => ['dondon@gmail.com'],
        ['first_name'] => ['don'],
        ['last_name'] => ['jones'],
        ['role']=>['u1']    ));

http://php.net/manual/en/function.http-build-query.php

UPDATE

I just read Pandadoc API. They accept json data and your data was invalid. Also content type.

This should work:

<?php

$url                = 'https://api.pandadoc.com/public/v1/documents'; 
$docurl             = "myurl.com/document.pdf";

$postfields         = array();
$postfields['name'] = 'PSA';
$postfields['url']  = $docurl;
$postfields['recipients'] = array(
    array(
            'email'      => 'dondon@gmail.com',
            'first_name' => 'don',
            'last_name'  => 'jones',
            'role'       => 'u1'
        )
);
$data_string = json_encode( $postfields );

$headr = array();
$headr[] = 'Content-length: '.strlen( $data_string );
$headr[] = 'Content-type: application/json';
$headr[] = "Authorization: Bearer $ACCESS_TOKEN";

$ch = curl_init( $url );

curl_setopt( $ch, CURLOPT_FOLLOWLOCATION, true );
curl_setopt( $ch, CURLOPT_VERBOSE, 1 );
curl_setopt( $ch, CURLOPT_SSL_VERIFYPEER, false );
curl_setopt( $ch, CURLOPT_CUSTOMREQUEST, "POST" );
curl_setopt( $ch, CURLOPT_POSTFIELDS, $data_string );
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch, CURLOPT_HTTPHEADER, $headr );

$result = curl_exec( $ch );

?>

I changed the code above but I am still getting the same {"type": "validation_error", "detail": {"url": ["This field is required."], "name": ["This field is required."]}}Array ( [name] => PSA [url] => myurl.com/document.pdf [recipients] => Array ( ) ) Error.. also when I print_r($postfields), the keys and values for ['recipients'] is missing — Dino Anastos, Mar 06 '15 at 19:32
Hey those changes worked!! You are the man. I spent all day on this and you pegged it!! You are the man!! — Dino Anastos, Mar 07 '15 at 00:23
I tried to up vote this but I couldnt since I need 15 reputation, but you indeed answered my question. — Dino Anastos, Mar 07 '15 at 00:24
one note to add to this, if you json_encode the parameterss, you get back an invalid url from the API because json_encode throws a backslash behind every forward slash... so I modified the code so that wont happen.... — Dino Anastos, Mar 07 '15 at 00:28
No problem, glad to help. You should still be able to mark this answer as accepted. You don't need to upvote. See [What should I do when someone answers my question?](http://stackoverflow.com/help/someone-answers) — Rene Korss, Mar 07 '15 at 09:26
