Error in image upload - php

I want to post some data including a image.I am using curl in php for this.My code is below-
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_VERBOSE, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-type: multipart/form-data"));
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (X11; Linux i686; rv:6.0) Gecko/20100101 Firefox/6.0Mozilla/4.0 (compatible;)");
curl_setopt($ch, CURLOPT_URL, 'http://postacity.co.uk:8080/shine/pp/upload/');
curl_setopt($ch, CURLOPT_POST, true);
$post = array(
'creatorid' => '119',
'userfile' => '#/temp/fgf.jpg',
'notice' => 'Image1',
'catid' => '1',
'title' => 'bookofzeus',
'boardid' => '332',
);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
$response = curl_exec($ch);
if(curl_errno($ch)) {
echo 'Error: ' . curl_error($ch);
}
else {
echo $response;
}
}
Every time i am getting the same error
Error: failed creating formpost data
Am i doing any mistake.I have searched for this problem but still no solution found.

The path to the file is the problem: '#/temp/fgf.jpg'
You should take a look at this bug gescription: Bug 50060 - failed creating formpost data if post array value starts with #
The solutions of this problem for example at php freaks.
And use absolute path to the files.

Refer this its working
<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_VERBOSE, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible;)");
curl_setopt($ch, CURLOPT_URL, _VIRUS_SCAN_URL);
curl_setopt($ch, CURLOPT_POST, true);
// same as <input type="file" name="file_box">
$post = array(
"file_box"=>"#/path/to/myfile.jpg",
"username"=>"foobar",
"password"=>"secret",
"submit"=>"submit"
);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
$response = curl_exec($ch);
?>

Symfony2 Authentication via HTTP headers

I have Symfony2 app running, that has login mechanism implemented.
However I need somehow to send request from other app, that checks whether requested URL exists on that system:
For example there's request http://myapp/order/1111 that I need to check whether it returns 200 OK header or 404 Not Found status;
When I send request it's unauthorized and get's redirected to login page /login which is returns 200 OK status header.
What I need is to somehow safely bypass login mechanism. Is there a way that I could add login credentials to request, or create additional login method?
EDIT:
As suggested in comments, I tried to use curl. But I can't figure out how make it work. Here's what I'v got, but It doesn't work.
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://localhost/en/login');
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6');
curl_setopt($ch, CURLOPT_TIMEOUT, 60);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_COOKIESESSION, true);
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie.txt');
curl_setopt($ch, CURLOPT_COOKIEFILE, 'cookie.txt');
curl_setopt($ch, CURLOPT_POST, true);
$html = new DOMDocument();
$html->loadHTML(curl_exec($ch));
if (curl_error($ch)) {
echo(curl_error($ch));
}
$csrf_token = $html->getElementById('csrf_token')->getAttribute('value');
curl_setopt($ch, CURLOPT_URL, 'http://localhost/en/login');
//curl_setopt($ch, CURLOPT_REFERER, 'http://localhost/en/login');
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query(array(
'_username' => 'login_username',
'_password' => 'login_password',
'_remember_me' => 'on',
'_csrf_token' => $csrf_token
)));
curl_setopt($ch, CURLOPT_POST, true);
$result = curl_exec($ch);
if (curl_error($ch)) {
echo(curl_error($ch));
}
echo $result;
curl_close($ch);
Any suggestions, how to work with curl on this case?
I wrote a solution to this problem if anyone else struggling with this:
$ch = curl_init();
//get login form
curl_setopt($ch, CURLOPT_URL, $login_url);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.6) Gecko/20070725 Firefox/2.0.0.6');
curl_setopt($ch, CURLOPT_TIMEOUT, 60);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_COOKIESESSION, true);
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_path);
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_path);
//parse html to get csrf_token, I added id attribute to it for easier retrieving
$html = new DOMDocument();
$html->loadHTML(curl_exec($ch));
$csrf_token = $html->getElementById('csrf_token')->getAttribute('value');
if (curl_error($ch)) {
throw new Exception(curl_error($ch));
}
//send post request to login_check with parameters (csrf_token included)
curl_setopt($ch, CURLOPT_URL, $check_url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query(array(
'_username' => $username,
'_password' => $password,
'_remember_me' => 'on', //if you use remember me functionality
'_csrf_token' => $csrf_token
)));
curl_exec($ch);
if (curl_error($ch)) {
throw new Exception(curl_error($ch));
}
//request login protected urls
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, false);
curl_exec($ch);
if (curl_error($ch)) {
throw new Exception(curl_error($ch));
}
$info = curl_getinfo($ch);
curl_close($ch);
//I used this code in a function returning url and http_code for further processing
return array(
'url' => $info['url'],
'http_code' => $info['http_code']
);
I was having a problem with localization. I used to pass login_check url with locale like this http://localhost/en/login_check, by removing locate I fixed the problem: http://localhost/login_check

PHP Curl - Upload file to Sharepoint

Should I be able to use PHP Curl to upload a file to Sharepoint. I have this logic that I am using at the moment to "try" and upload to "My Shared Document" for now.
$the_file = file_get_contents('index.html');
$user = '&&&&&&&';
$pass = '&&&&&&&';
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_VERBOSE, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-type: multipart/form-data"));
curl_setopt($ch, CURLOPT_USERPWD, "$user:$pass");
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (X11; Linux i686; rv:6.0) Gecko/20100101 Firefox/6.0Mozilla/4.0 (compatible;)");
curl_setopt($ch, CURLOPT_URL, 'https://&&&&.net/personal/&&&&&&&/Shared%20Documents/Forms/AllItems.aspx');
curl_setopt($ch, CURLOPT_POST, true);
$post = array('file_contents' => "the_file");
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
$response = curl_exec($ch);
if(curl_errno($ch)) {
echo json_encode('Error: ' . curl_error($ch));
}
else {
echo json_encode($response);
}
Any help is much appreciated.
Thanks

When you upload a file through curl, few things you need to consider.
use # with file path to upload the file directly. example:
$post = array('file_contents' => "#/home/xyz/the_file");
// if you have parameter with the file, then it will be,
$post = array('uid' => 110, 'file_contents' => "#/home/xyz/the_file");
2. You don't need to specify this header "Content-type: multipart/form-data". It will be added automatically when you use # with your file parameter.

POST Request using CURL and PHP not working properly

I am trying to programmatically process my statement using the form at http://nlp.stanford.edu:8080/corenlp/process. I have the following code snippet in PHP/CURL. However, instead of processing the statement, it is returning the HTML for the form - as if the post parameters are not being sent. I checked that I am sending the required paramaters. Can someone guide me as to what I am doing wrong?
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://nlp.stanford.edu:8080/corenlp/process");
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($ch, CURLOPT_USERAGENT,"Mozilla/14.0 (compatible; MSIE 6.0; Windows NT 5.1)");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_POST, true);
$data = array(
'outputFormat' => 'xml',
'input' => 'Here is a statement to process',
'Process' => 'Submit Query'
);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
$result = curl_exec($ch);
echo $result;
You have to convert the $data array into a string... Also, Be sure to urlencode() the individual values.
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://nlp.stanford.edu:8080/corenlp/process");
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($ch, CURLOPT_USERAGENT,"Mozilla/14.0 (compatible; MSIE 6.0; Windows NT 5.1)");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_POST, true);
$data = array(
"outputFormat" => "xml",
"input" => "Here is a statement to process",
"Process" => "Submit Query"
);
$data_string = "";
foreach($data as $key=>$value){ /// YOU HAVE TO DO THIS
$data_string .= $key.'='.urlencode($value).'&'; /// AND THIS
}
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
$result = curl_exec($ch);
echo $result;

Get html of https after logging in

I would like to get the html of the page. After some google-ing, i found following code, which isn't working.
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERPWD, "$username:$passwd");
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
$output = curl_exec($ch);
$info = curl_getinfo($ch);
curl_close($ch);
echo $output;
edit: something like this then:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, '');
curl_setopt($ch, CURLOPT_POSTFIELDS,'username='.urlencode($username).'&passwd='.urlencode($passwd));
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_COOKIEJAR, "/tmp/my_cookies.txt");
curl_setopt($ch, CURLOPT_COOKIEFILE, "/tmp/my_cookies.txt");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt( $ch, CURLOPT_SSL_VERIFYPEER, false );
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.3) Gecko/20070309 Firefox/2.0.0.3");
curl_setopt($ch, CURLOPT_REFERER, "");
$output = curl_exec($ch);
echo $output
This just shows the target page, it doesn't log in, nor does it return the html code.
edit 2: now tried with $data = array('username' => $username, 'passwd' => $passwd); and curl_setopt($ch, CURLOPT_POSTFIELDS,$data);
This shows the same as above + an error: Request Entity Too Large
That page does not use HTTP Basic Authentication.
You need to make an HTTP request to match what submitting the form would sent, then you need to process the response (which will probably involve storing cookies).

Posting images via CURL to a form

I've had a tough time trying to find a solution for the following problem, I need to use curl to submit a form on a website, however it also needs to upload a picture its a normal input file field
<input type="file" name="image"/>
I have a class and the curl function is defined like this
function fetch($url, $username='', $data='', $proxy=''){
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, true);
if(isset($proxy)) {
curl_setopt($ch,CURLOPT_TIMEOUT,30);
curl_setopt($ch, CURLOPT_PROXY, $proxy);
curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 1);
curl_setopt($ch, CURLOPT_PROXYPORT, $proxy);
curl_setopt($ch, CURLOPT_PROXYUSERPWD, 'proxyadmin:parola');
}
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FRESH_CONNECT,true);
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/3.0 (compatible; MSIE 6.0; Windows NT 5.0)");
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_MAXREDIRS, 5);
if($username) {
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookie/{$username}.txt");
curl_setopt($ch, CURLOPT_COOKIEJAR, "cookie/{$username}.txt");
}
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
if (is_array($data) && count($data)>0){
curl_setopt($ch, CURLOPT_POST, true);
$params = http_build_query($data);
curl_setopt($ch, CURLOPT_POSTFIELDS, $params);
}
if (is_array($this->headers) && count($this->headers)>0){
curl_setopt($ch, CURLOPT_HTTPHEADER, $this->headers);
}
$this->result = curl_exec($ch);
$curl_info = curl_getinfo($ch);
$header_size = $curl_info["header_size"];
$this->headers = substr($this->result, 0, $header_size);
$this->http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
$this->error = curl_error($ch);
curl_close($ch);
}
Anyone could help me? very lost
If you change the following block of code:
// from
if (is_array($data) && count($data)>0){
curl_setopt($ch, CURLOPT_POST, true);
$params = http_build_query($data);
curl_setopt($ch, CURLOPT_POSTFIELDS, $params);
}
// to
if (is_array($data) && count($data)>0) {
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
}
And to have it post the file uploaded by the user, set up your data array like this:
// make sure $_FILES['file'] has been uploaded and is valid
$data = array('field' => 'value',
'name' => 'test',
'email' => 'something',
'file' => '#' . $_FILES['file']['tmp_name']
);
fetch($url, $username, $data);
That will tell curl to send a form post with a file upload. By setting the post fields to an array and prepending an & to the full path of a file that is a value of the array, curl will send an multipart/form-data post request with your file upload.
See curl file upload example
