Send File Via Curl from Form Post in PHP

Send file via cURL from form POST in PHP

Here is some production code that sends the file to an ftp (may be a good solution for you):

// This is the entire file that was uploaded to a temp location.
$localFile = $_FILES[$fileKey]['tmp_name']; 

$fp = fopen($localFile, 'r');

// Connecting to website.
$ch = curl_init();

curl_setopt($ch, CURLOPT_USERPWD, "email@email.org:password");
curl_setopt($ch, CURLOPT_URL, 'ftp://@ftp.website.net/audio/' . $strFileName);
curl_setopt($ch, CURLOPT_UPLOAD, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 86400); // 1 Day Timeout
curl_setopt($ch, CURLOPT_INFILE, $fp);
curl_setopt($ch, CURLOPT_NOPROGRESS, false);
curl_setopt($ch, CURLOPT_PROGRESSFUNCTION, 'CURL_callback');
curl_setopt($ch, CURLOPT_BUFFERSIZE, 128);
curl_setopt($ch, CURLOPT_INFILESIZE, filesize($localFile));
curl_exec ($ch);

if (curl_errno($ch)) {

    $msg = curl_error($ch);
}
else {

    $msg = 'File uploaded successfully.';
}

curl_close ($ch);

$return = array('msg' => $msg);

echo json_encode($return);

how to upload file using curl with PHP

Use:

if (function_exists('curl_file_create')) { // php 5.5+
  $cFile = curl_file_create($file_name_with_full_path);
} else { // 
  $cFile = '@' . realpath($file_name_with_full_path);
}
$post = array('extra_info' => '123456','file_contents'=> $cFile);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$target_url);
curl_setopt($ch, CURLOPT_POST,1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
$result=curl_exec ($ch);
curl_close ($ch);

Important hint for PHP 5.5+:

Now we should use https://wiki.php.net/rfc/curl-file-upload but if you still want to use this deprecated approach then you need to set curl_setopt($ch, CURLOPT_SAFE_UPLOAD, false);

Php Curl send File with data

Here the sample curl request

$curlFile = curl_file_create($uploaded_file_name_with_full_path);
$post = array('val1' => 'value','val2' => 'value','file_contents'=> $curlFile );
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$your_url);
curl_setopt($ch, CURLOPT_POST,1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
$result=curl_exec ($ch);
curl_close ($ch);

Don't forget to put the appropriate header.

You can also find good source here

to send file via CURL. Make sure that you are passing your file on file_contents key in above code.

How to upload files with POST form-data in PHP?

Try this one:

<?php

$url = "https://sm.ms/api/v2/upload";

// I guess the file is in the same directory as this script
$file = __DIR__.'/test.png'; 

$headers = [
    'Content-Type: multipart/form-data',
    'User-Agent: '.$_SERVER['HTTP_USER_AGENT'],
];

$fields = [
    'smfile' => new CURLFile($file, 'image/png')
];

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);

var_dump(curl_exec($ch));
var_dump(curl_error($ch));

?>

How can I use cURL to post form data in php?

since no answer got it right thus far (at least not with an approach that would work in php 5.6+), here goes: the equivalent php curl_ code would be:

$ch = curl_init ( 'https://apiprovider.com/api/v0/imports?token=[KEY]' );
curl_setopt_array ( $ch, array (
        CURLOPT_POST => 1,
        CURLOPT_POSTFIELDS => array (
                'file' => new CURLFile ( '/home/USERNAME/import.csv' ) 
        ) 
) );
curl_exec ( $ch );

(i would also recommend setting CURLOPT_ENCODING to emptystring, especially if you expect the response to be compressible, that would be the equivalent of adding --compressed to the curl command line, and might speed things up)

how to send a Data Form including file, from PHP ContactForm7 with Curl

I ended up doing this in functions.php

$submission = WPCF7_Submission::get_instance();
$data = $submission->get_posted_data();
$files = $submission->uploaded_files();
$file_invoice = $files['file_invoice'][0];

$cFile = "";
if (function_exists('curl_file_create')) 
   { // php 5.5+
          $cFile = curl_file_create($file_invoice);
   } 
else { $cFile = '@' . realpath($file_invoice); }

    $fields = array(
                        'user_mail'         => $user_mail,
                        'user_phone'        => $user_phone,
                        'file'              => $cFile
                    ); 

 $curl = curl_init();
 $curlParams = array(
            CURLOPT_RETURNTRANSFER  => 1,
            CURLOPT_URL             => 'https://....',
            CURLOPT_POST            => 1,
            CURLOPT_POSTFIELDS      => $fields
                   );

curl_setopt_array($curl, $curlParams);
$resp = curl_exec($curl);

$responseStatusCode = curl_getinfo($curl, CURLINFO_HTTP_CODE);
curl_close($curl);

Can't send file as form data using cURL

If you want to be able to access the file's contents using $app->request->post('content');, your curl request must use a < instead of an @ for the content field,

curl -i http://localhost/test/index.php -X POST -F "name=file.png" \
  -F "content=</var/www/html/test/file.png"

From curl's manpage:

To force the
'content' part to be a file, prefix the file name with an @ sign. To just get the content part from a file, prefix the file name with the symbol <. The difference between @ and < is then that @ makes a file get attached in the post as a file upload,
while the < makes a text field and just get the contents for that text field from a file.

By using @, you marked the field as a file. Technically, this adds a Content-Disposition header to the field (RFC 2388, if you're interested). PHP detects that and automatically stores the field inside $_FILES instead of $_POST, as Raphaël Malié remarked in a comment, which is why you can't access the contents using $app->request->post.

You should consider to switch to using $_FILES in your backend, though, if you want to support uploading using browsers' <input type=file> elements and forms. Those always set a Content-Disposition header.

Send file using multipart/form-data request in php

If you work with CURL, you have to just:

1, set header 'Content-Type' as 'multipart/form-data;'

2, set option 'RETURNTRANSFER' of curl to true (use option method of curl)

3, set option 'POST' of curl to true (use option method of curl)

4, get source of your file (what you get from fopen in PHP):

$tempFile = tempnam(sys_get_temp_dir(), 'File_');                
file_put_contents($tempFile, $source);
$post = array(
    "uploadedFile" => "@" . $tempFile, //"@".$tempFile.";type=image/jpeg",
);

5, use post method of CURL with parameter in $post variable
