Posting Multidimensional Array with PHP and Curl

Posting multidimensional array with PHP and CURL

You'd have to build the POST string manually, rather than passing the entire array in. You can then override curl's auto-chose content header with:

curl_setopt($c, CURLOPT_HTTPHEADER, array("Content-type: multipart/form-data"));

Serializing/json-ifying would be easier, but as you say, you have no control over the receiving end, so you've got a bit of extra work to do.

Sending a multidimensional array using cURL and foreach in php

Thanks to This awesome reply I understood I must use $POST only.

sender:

<?php

function post_to_url($url, $data) {
    $post = curl_init();

    curl_setopt($post, CURLOPT_URL, $url);
    curl_setopt($post, CURLOPT_POSTFIELDS, http_build_query($data));
    curl_setopt($post, CURLOPT_RETURNTRANSFER, true);

    $result = curl_exec($post);
    curl_close($post);
}

if (isset($_POST['submit'])){

    $name = addslashes(strip_tags($_POST["name"]));
    $address = addslashes(strip_tags($_POST["address"]));
    $email = addslashes(strip_tags($_POST["email"]));
    $job = addslashes(strip_tags($_POST["job"]));

    $list = array (
        array('name', "$name"),
        array('address', "$address"),
        array('email', "$email"),
        array('job', "$job"),
        array(''),
        array('options', 'status', 'link','time', 'note','check' )
    );

    // Merge the 2 arrays together
    $final_array = array_merge($list, $_POST['prefs']);

    // Send through CURL
    post_to_url("http://192.168.10.10/receiver.php", $final_array);

    header("Location:index.php");
    exit;
}

?>

receiver:

<?php
$csv = fopen( "/home/user/file.csv", 'w+' );
foreach ($_POST as $fields) {
    fputcsv($csv, $fields, ";");
}
fclose($csv);
?>

And now it works.

how to send multidimensional array post data in php?

I'm not sure why you pass your data as json_string, but obviously a json string is considered a url_encoded string and decodes in what you get in your variables.

If json is not a requirement - you can pass your array directly to curl_setopt or encode it with http_build_query:

// passing raw array:
curl_setopt($ch, CURLOPT_POSTFIELDS, $jsonData);

// passing query string:
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($jsonData));

Post multidimensional array using CURL and get the result on server

cURL can only accept a simple key-value paired array where the values are strings, it can't take an array like yours which is an array of objects. However it does accept a ready made string of POST data, so you can build the string yourself and pass that instead:

$str = http_build_query($array);

...

curl_setopt($ch, CURLOPT_POSTFIELDS, $str);

A print_r($_POST) on the receiving end will show:

Array
(
    [0] => Array
        (
            [id] => 1
        )

    [1] => Array
        (
            [id] => 0
        )

    [2] => Array
        (
            [id] => 11
        )

)

How to send a multidimensional array with PHP cURL without array keys from the nested arrays?

If you don’t want to write your own version of http_build_query, then I’d suggest you modify the version from this user comment in the manual, http://php.net/manual/en/function.http-build-query.php#111819

    $query = http_build_query($query);
    $query = preg_replace('/%5B[0-9]+%5D/simU', '%5B%5D', $query);

They are replacing foo[xy] with foo[] here - since you don’t want to keep the [] either, just replace '%5B%5D' in the preg_replace call with an empty string instead.

How to Send Multidimensional Json array through php cURL

Try looking at the following example: POSTing JSON Data With PHP cURL

Useful excerpt:

$data = array("name" => "Hagrid", "age" => "36");                                                                    
$data_string = json_encode($data);                                                                                   

$ch = curl_init('http://api.local/rest/users');                                                                      
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                                                                     
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);                                                                  
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);                                                                      
curl_setopt($ch, CURLOPT_HTTPHEADER, array(                                                                          
    'Content-Type: application/json',                                                                                
    'Content-Length: ' . strlen($data_string))                                                                       
);                                                                                                                   

$result = curl_exec($ch);

PHP Convert Multi-dimensional Array to Query String for curl POST

You can use http_build_query() to create a string that you can pass to cURL:

<?php
$posted = ["foo"=>"bar", "address"=>["line1"=>"foo"]];
$string = http_build_query($posted);

echo $string;

Output:

foo=bar&address%5Bline1%5D=foo

You can also get access to the raw POST data using input:// but that is rarely necessary, unless dealing with non-HTML data.

PHP CURL Multidimensional/JSON Post

If you want to post exactly provided JSON sample, main error is in this line:

'Legs' => array ( ... ),

This code produce this JSON:

{"FirstOrder":{"Legs":{"Id":"0",...}},...}

instead of:

{"FirstOrder":{"Legs":[{"Id":"0",...}]},...}

Change the “Legs” line in this way:

'Legs' => array( array(
    'Id' => '0',
    'SecurityId' => '643',
    'SecurityName' => 'AAPL',
    'SecurityExchange' => 'NASDAQ national market',
    'Side' => 'Buy',
    'Quantity' => '100'
)),

Also (although I don't think that this can cause issues), if you want numbers encoded as numbers and booleans encoded as booleans, remove relative wrapping quotes:

'SymbolLastPrice' => 93.72,
(...)
'AllOrNone' => false,
(...)
'LimitOffset' => 0,
(...)
