PHP - Posting To A Forum Using Curl

I am posting this into the Newbie forum cause this seems nebieish to me...

Ok i have a few files that make up a set of pages

Topbar.php
index.php
info_birmingham.php ( i want the title to match the info page i have a few cities )
footer.php

OK so obviously the <title> is in top bar and i am trying to display the city name in the title which would be gotten from the info_city page

so in topbar i have...
<title><?php echo ("$city"); ?> - <?php echo COMPANY; ?></title>

and then in the info_city page i have at the top of the page

<?php
$city = "Birmingham";
?>

So i guess my question is why does the title not display the city name?

SOMEONE please help i have been pulling my hair out on this
you can see form the URL string that index.php controls all of the pages and the info page has the data for each city
http://www.skbk.com/OaklandCounty/index.php?section=Birmingham

Thanks to anyone that might be able to shed some insight on this for me

Hi there,
OK, there is what I'm trying to accomplish - I want to send POST instantly when the page is loaded without "Submit" button or anything like that.
Here how it looks using JavaScript:
Code: [Select]
<form name="postdata" action="http://www.mywebsite.com/post.php" method="post">
    <input name="data" type="text" value="1"/>
</form>
<script type="text/javascript" language="JavaScript">
document.postdata.submit();
</script>

Works fine with JavaScript, however i can't use it.

Here is reference for CURL: http://php.net/manual/en/book.curl.php
I found this curl_post function at php.net to simplify things up.
<?php

/**
 * Send a POST requst using cURL
 * @param string $url to request
 * @param array $post values to send
 * @param array $options for cURL
 * @return string
 */
function curl_post($url, array $post = NULL, array $options = array())
{
    $defaults = array(
        CURLOPT_POST => 1,
        CURLOPT_HEADER => 0,
        CURLOPT_URL => $url,
        CURLOPT_FRESH_CONNECT => 1,
        CURLOPT_RETURNTRANSFER => 1,
        CURLOPT_FORBID_REUSE => 1,
        CURLOPT_TIMEOUT => 4,
        CURLOPT_POSTFIELDS => http_build_query($post)
    );

    $ch = curl_init();
    curl_setopt_array($ch, ($options + $defaults));
    if( ! $result = curl_exec($ch))
    {
        trigger_error(curl_error($ch));
    }
    curl_close($ch);
    return $result;
}
$test = curl_post("http://www.mywebsite.com/post.php", array("data" => "1"));
print($test);
?>

Looks like it uses GET instead POST (used sniffer to verify this).
I'm trying to send POST data to other host, if that matters.
Any help would be appreciated.
Thanks in advance.

Hey guys,

Recently I bumped into a little coding problem. I'm trying to submit information to a multi-part form (including an image upload). The receiving server couldn't read my input, figured I had a nill object somewhere (RoR). First I thought the problem was in my curl setopts, but I think they are fine. It looks like the problem is with the data I'm submitting.

I read a bit about multi part posting, and every article I read advised to make a postfield array, which curl would interpret and send out correctly. I did and this was my resulting array:

$postfield = array ("social[comments]" => "Test", "avatar_file" => "", "friend_avatar_file" => "", "forum_avatar_file" => "", "social[signature]" => "", "forum_signature_file" => "", "save_profile.x" => "25", "save_profile.y" => "9");

That failed. So I tried making it into a URLENCODED string:

$postfield = "social%5Bcomments%5D=".stripslashes($_POST['textarea'])."&avatar_file=&friend_avatar_file=&forum_avatar_file=".$file."&social%5Bsignature%5D=&forum_signature_file=&save_profile.x=25&save_profile.y=9";

This finally worked. I was able to submit the info I wanted. I'd like to send a file with it this time though. I'd need to put this into a postfield array to work though.

if(!$file = upload( )) { $file = ''; } else { $file = '@'.$file; }

function upload( ) {
if(isset($_FILES['file']) && !empty($_FILES['file']['name']))
{
$uploaddir = "temp";  

if(is_uploaded_file($_FILES['file']['tmp_name'])) {
move_uploaded_file($_FILES['file']['tmp_name'],$uploaddir.'/'.$_FILES['file']['name']);
$searchfile = $uploaddir.'/'.$_FILES['file']['name'];
return $searchfile;
}
}
return false;
}

So, I got the uploading covered. I need to put generate the postfield array though. I have the feeling the problem is with the brackets [ ] I'm using. I tried urlencoding the keys in the array, but that didn't work either.

Does anybody have an idea on how to handle brackets in post (multi-part) data?

Thanks in advance!

I'm trying to post to a (SMF) simplemachines 2.0 forum using curl.

I have logged in and I have tried sending all the fields, but when I try to post, I receive this message:

"The following error or errors occurred while posting this message:
Your session timed out while posting. Please try to re-submit your message."

Do any of you know why this happens? Is the problem that when I visit the posting url, they give me a cookie that expires if I leave the posting url?

I don't think the form is invalid, it looks like it has to do with the session. People at the simplemachines forum can have this problem when they try to post the ordinary way, but that is because of an inactivity period. Can my problem be because of a cookie?

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?

I look forward to your ideas.
