PHP - Curl Not Working

I am trying to create a remote login to one website using mine. The users will need to enter their username and password on my site, and if they are registered to my website, their login credentials will be sent to another website and a page will be retrieved. I am stuck at sending the users' data to the original site. The original site's viewsource is this..

<form method=post>
<input type="hidden" name="action" value="logon">
<table border=0>
<tr>
<td>Username:</td>
<td><input name="username" type="text" size=30></td>
</tr>
<tr>
<td>Password:</td>
<td><input name="password" type="password" size=30></td>
</tr>
<td></td>
<td align="left"><input type=submit value="Sign In"></td>
</tr>
<tr>
<td align="center" colspan=2><font size=-1>Don't have an Account ?</font> <a href="?action=newuser"><font size=-1 color="#0000EE">Sign UP Now !</font></a></td>
</tr>
</table>

I have tried this code, but not works.

<?php
$username="username"; 
$password="password"; 
$url="http://www.example.com/index.php"; 

$postdata = "username=".$username."&password=".$password;

$ch = curl_init(); 
curl_setopt ($ch, CURLOPT_URL, $url); 
curl_setopt ($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 ($ch, CURLOPT_FOLLOWLOCATION, 1); 
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt ($ch, CURLOPT_REFERER, $url); 
curl_setopt ($ch, CURLOPT_POSTFIELDS, $postdata); 
curl_setopt ($ch, CURLOPT_POST, 1); 
$result = curl_exec ($ch); 
header('Location: track.html'); 
//echo $result;  
curl_close($ch);
?>

Any help would be appreciated, Thanks in advance.

I have a CURL code that fetches some XML content from a remote server. I get the expected output on my localhost (XAMPP on windows). But from the live site(hosted on Linux), I get the CURL error:'couldn't connect to host'.

function DownloadUrl($Url, $p){
 
// is curl installed?
if (!function_exists('curl_init')){ 
die('CURL is not installed!');
}

       // create curl resource
        $ch = curl_init();

        // set url
        curl_setopt($ch, CURLOPT_URL, $Url);

   curl_setopt ($ch, CURLOPT_POSTFIELDS, $p);
   curl_setopt ($ch, CURLOPT_POST, 1);
        //return the transfer as a string
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

        // $output contains the output string
        $output = curl_exec($ch);
        
   if($output === false)
   echo 'Curl error: ' . curl_error($ch);
   else
     print $output;
        // close curl resource to free up system resources
        curl_close($ch);          
}

Hello PHP Freaks!

I have the following PHP Curl code which is supposed to fetch the twitter timeline feed for a specific username and parse and display it on a page, but for some reason Curl is unable to fetch data from twitter:

Code: [Select]
<?php
function get_data($url)
{
  $ch = curl_init();
  $timeout = 5;
  curl_setopt($ch,CURLOPT_URL,$url);
  curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
  curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,$timeout);
  $data = curl_exec($ch);
  curl_close($ch);
  return $data;
}

$json = get_data("https://api.twitter.com/1/statuses/user_timeline.json?include_entities=true&include_rts=true&screen_name=digioz&count=2");

if ($json != false)
{
    $obj = json_decode($json);
        
    foreach($obj as $var => $value)
    {
        echo "Message number: $var <br/>";    
        echo "Name: " . $obj[$var]->user->name;
        echo "Handle: " . $obj[$var]->user->screen_name . "<br/>";        
        echo "Message: " . $obj[$var]->text;        
        echo "Created" . $obj[$var]->created_at . "<br/>";                    
        echo "URL" . $obj[$var]->user->url . "<br/>";
        echo "Location" . $obj[$var]->user->location . "<br/>";       
        echo "<br/>";
    }
}
else
{
    echo "Could not fetch Twitter Data";
}
?>

Anyone have any idea why the data is not being fetched? If I copy and paste the URL into my browser window it returns results just fine, so I know the problem is not with the URL.

Thanks,
Pete

Hi All,

My goal is to process all redirects serverside and simply return the user to the 'final' URL.

Here's my function to get the final URL:
PHP Code:
function get_final_url($url){ 
    global $final_host; 
        $redirects = get_all_redirects($url); 
        if (count($redirects)>0){ 
          $final_url = array_pop($redirects); 
          if(substr($final_url,0,7) != 'http://' && !empty($final_host)) 
            { $final_url = 'http://'.$final_host.$final_url; } 
                return $final_url; 
        } else { 
                return $url; 
        } 

Here's the cURL execution:

$ch2 = curl_init();      
                        curl_setopt($ch2,CURLOPT_URL,$url); 
                        curl_setopt($ch2, CURLOPT_FOLLOWLOCATION, true); 
                        curl_setopt($ch2,CURLOPT_POST,''); 
                        curl_setopt($ch2,CURLOPT_POSTFIELDS,''); 
                        curl_exec($ch2); 
                        curl_close($ch2); 

For some reason, this works no problem, posts any data over to the URLs serverside, redirects serverside, and passes the client to the final URL, with none of the redirection displayed via HTTPWatch or any similar debug utility. Sometimes, however, it does show phases of redirection.

Any insight into what I might be doing incorrectly?

Thanks SO much in advance.

good day dear community,

i am workin on a Curl loop to fetch multiple pages:

i have some examples - and a question:

Example: If we want to get information from 3 sites with CURL we can do it like so:


$list[1] = "http://www.example1.com";
$list[2] = "ftp://example.com";
$list[3] = "http://www.example2.com";


After creating the list of links we should initialize the cURL multi handle and adding the cURL handles.


$curlHandle = curl_multi_init();
for ($i = 1;$i <= 3; $i++)
 $curl[$i] = addHandle($curlHandle,$list[$i]);


Now we should execute the cURL multi handle retrive the
content from the sub handles that we added to the cURL multi handle.

ExecHandle($curlHandle);
for ($i = 1;$i <= 3; $i++)
{
 $text[$i] =  curl_multi_getcontent ($curl[$i]);
 echo $text[$i];
}

In the end we should release the handles from the cURL multi handle by calling curl_multi_remove_handle and close the cURL multi handle!

If we want to another Fetch of sites with cURL-Multi - since this is the most pretty way to do it!
Well I am not sure bout the string concatenation. How to do it - Note I want to fetch several hundred pages:
see the some details for this target-server sites - /(I have to create a loop over several hundred sites).

    * siteone.example/?show_subsite=9009
    * siteone.example/?show_subsite=9742
    * siteone.example/?show_subsite=9871

.... and so on and so forth Question: How to appy this loop into the array of the curl-multi?

$urls = array(

   );

$mh = curl_multi_init();

foreach ($urls as $i => $url) {
       $conn[$i]=curl_init($url);
       curl_setopt($conn[$i],CURLOPT_RETURNTRANSFER,1);//return data as string 
       curl_setopt($conn[$i],CURLOPT_FOLLOWLOCATION,1);//follow redirects
       curl_setopt($conn[$i],CURLOPT_MAXREDIRS,2);//maximum redirects
       curl_setopt($conn[$i],CURLOPT_CONNECTTIMEOUT,10);//timeout
       curl_multi_add_handle ($mh,$conn[$i]);
}

do { $n=curl_multi_exec($mh,$active); } while ($active);

foreach ($urls as $i => $url) {
       $res[$i]=curl_multi_getcontent($conn[$i]);
       curl_multi_remove_handle($mh,$conn[$i]);
       curl_close($conn[$i]);
}
curl_multi_close($mh);


print_r($res);

?>





I look forward to your ideas.

I have just installed cURL and am learn to use it but I'm not sure exactly what I am doing.  For example I have a page with this code on it.

curl_setopt($ch2, CURLOPT_POST, 1);
curl_setopt($ch2,CURLOPT_POSTFIELDS,'number=6');
$return = curl_exec($ch2); 

echo ($return);

curl_close($ch2);

Hello, I'm new to lot of this and especially php.

I'm having hard time with one of my app that I created. 
If you go to ticketlawyerorlando.com/sms5.html and you try to send text, (which is set to go to only one number (mine)) than I get error code from php that is supposed to curl it. 


Error:

Warning: curl_setopt() [function.curl-setopt]: Invalid curl configuration option in /home/content/s/j/1/sj10mil/html/ticketlawyerorlando/sms5.php on line 10

//print $code;
//print $response;
print "SUCCESS";
curl_close($curl_handle);
?>
</body>
</html>

In my php, the URL that's being curled, in the part where it says "test4" that should be actual message that  is typed in the form but I don't know what kind of parameter to insert there in order for it to send message that's written, it always sends message "test4".

Please, if you could help me I would greatly appreciate it.

Thank You so much again.

Ok, I'm new to this and I don't know much about PHP, much less Curl and how to use the functions inside of PHP:

http://us.php.net/manual/en/book.curl.php

However, I need to do something with this.  I have to create this curl.php file, inside that file I need to take the $_POST array and send it to a different php file... I'm not sure how to do this.  And yes, I only need that.  I'd post the source, but my company's proprietary policies prevent me.
