Passing $_Post Values With Curl

Passing $_POST values with cURL

Should work fine.

$data = array('name' => 'Ross', 'php_master' => true);

// You can POST a file by prefixing with an @ (for <input type="file"> fields)
$data['file'] = '@/home/user/world.jpg';

$handle = curl_init($url);
curl_setopt($handle, CURLOPT_POST, true);
curl_setopt($handle, CURLOPT_POSTFIELDS, $data);
curl_exec($handle);
curl_close($handle)

We have two options here, CURLOPT_POST which turns HTTP POST on, and CURLOPT_POSTFIELDS which contains an array of our post data to submit. This can be used to submit data to POST <form>s.

---

It is important to note that curl_setopt($handle, CURLOPT_POSTFIELDS, $data); takes the $data in two formats, and that this determines how the post data will be encoded.

1. $data as an array(): The data will be sent as multipart/form-data which is not always accepted by the server.

   $data = array('name' => 'Ross', 'php_master' => true);
   curl_setopt($handle, CURLOPT_POSTFIELDS, $data);
   

2. $data as url encoded string: The data will be sent as application/x-www-form-urlencoded, which is the default encoding for submitted html form data.

   $data = array('name' => 'Ross', 'php_master' => true);
   curl_setopt($handle, CURLOPT_POSTFIELDS, http_build_query($data));
   

I hope this will help others save their time.

• curl_setopt

CURL + Passing $_POST variables/array

In my opinion the best way (secure) method for passing username and password as HTTP HEADER AUTHENTICATION WITH CURL.

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

$username = $_POST['username'];
$passwd = $_POST['passwd'];

$data = array('serialno' => '12345');    

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://www.domain.com/scripts/curl/index_general.php');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt($ch, CURLOPT_POST, true );
curl_setopt($ch, CURLOPT_USERPWD,'username:password'); // set your username and password
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($ch, CURLOPT_REFERER,'http://www.domain.com.au');
curl_setopt($ch, CURLOPT_POSTFIELDS,$data);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: text/plain')); 
$result = curl_exec($ch);
curl_close($ch);
echo $result;
}

In index_general.php

you can access the http username and password as

$_SERVER['PHP_AUTH_USER'] and $_SERVER['PHP_AUTH_PW']

Passing GET variables in a PHP CURL POST request

It seems that you are doing a GET request, so the post variables will never be send to the server. You could just add the parameters as a query string to the url.

Like so:

$curl_connection = curl_init('http://10.219.5.109:9000/mean?sample=1000');
$result = curl_exec($curl_connection);
print_r(curl_getinfo($curl_connection));

If you want the data to be dynamic, you can do it like this:

$post_string = 'sample=1000';
$curl_connection = curl_init('http://10.219.5.109:9000/mean?' . $post_string);

PHP, cURL, and HTTP POST example?

<?php
//
// A very simple PHP example that sends a HTTP POST to a remote site
//

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL,"http://www.example.com/tester.phtml");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,
            "postvar1=value1&postvar2=value2&postvar3=value3");

// In real life you should use something like:
// curl_setopt($ch, CURLOPT_POSTFIELDS, 
//          http_build_query(array('postvar1' => 'value1')));

// Receive server response ...
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$server_output = curl_exec($ch);

curl_close ($ch);

// Further processing ...
if ($server_output == "OK") { ... } else { ... }
?>

Passing form variable into php curl request

Try to json_encode your params

$params = [
  "method"=>"liststreamitems",
  "params"=>["Device"],
  "chain_name"=>$ChainName
];

Then pass it to the option CURLOPT_POSTFIELDS like this

CURLOPT_POSTFIELDS => json_encode($params);

can't pass the post value to curl

Just use PHP's built-in curl commands:

<?php
if(isset($_POST['conversation'])) {
    $data = array("input"=>array("text"=>$_POST["conversation"]));
    $url = "https://gateway.watsonplatform.net/conversation/api/v1/workspaces/a9379972-d820-4cdf-b1cb-ad0af898a534/message?version=2016-07-11";
    $ch = curl_init($url);
    curl_setopt_array($ch, array(
        CURLOPT_RETURNTRANSFER => true,
        CURLOPT_POST => true,
        CURLOPT_USERPWD => "username:password",
        CURLOPT_HTTPHEADER => array("Content-Type:application/json"),
        CURLOPT_POSTFIELDS => json_encode($data),
    ));
    $response = curl_exec($ch);
    curl_close($ch);
    print_r(json_decode($response));
}
?>

How do I submit POST data using PHP and cURL?

function post($requestJson) {

    $postUrl = $this->endpoint."?access_token=".$this->token;

    //Get length of post
    $postlength = strlen($requestJson);

    //open connection
    $ch = curl_init();

    //set the url, number of POST vars, POST data
    curl_setopt($ch,CURLOPT_URL,$postUrl);
    curl_setopt($ch,CURLOPT_POST,$postlength);
    curl_setopt($ch,CURLOPT_POSTFIELDS,$requestJson);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    $response = curl_exec($ch);

    //close connection
    curl_close($ch);

    return $response;
}
