HTTP POST for Posting a Form

Hombre_Ingwar

Hello.
I need to write a script posting data to a site in such form

<table border="0" cellspacing="0" cellpadding="0" width="100%">
<tr>
<td align="left">Name<input type="Text" name="PostMenName" size="20" maxlength="20" value=""></font>
</td>
<td align="left">Email:<input type="Text" name="PostMenMail" size="20" maxlength="35" value=""></font>
</td>
<td align="RIGHT"><font size="2"><input type="Submit" name="submiting" value="SUBMIT" align="Left"></font></td>
</tr>
</table>

</td></tr></table></form>

I have a function for working with POST method.

/ sendToHost

 * Params:
 *   $host      - Just the hostname.  No [url]http://[/url] or 
                  /path/to/file.html portions
 *   $method    - get or post, case-insensitive
 *   $path      - The /path/to/file.html part
 *   $data      - The query string, without initial question mark
 *   $useragent - If true, 'MSIE' will be sent as 
                  the User-Agent (optional)
 *
 * Examples:
 *   sendToHost('www.google.com','get','/search','q=php_imlib');
 *   sendToHost('www.example.com','post','/some_script.cgi',
 *              'param=First+Param&second=Second+param');
 */

function sendToHost($host,$method,$path,$data,$useragent=0)
{
    // Supply a default method of GET if the one passed was empty
    if (empty($method)) {
        $method = 'GET';
    }
    $method = strtoupper($method);
    $fp = fsockopen($host, 80);
    if ($method == 'GET') {
        $path .= '?' . $data;
    }
    fputs($fp, "$method $path HTTP/1.1\r\n");
    fputs($fp, "Host: $host\r\n");
    fputs($fp,"Content-type: application/x-www-form- urlencoded\r\n");
    fputs($fp, "Content-length: " . strlen($data) . "\r\n");
    if ($useragent) {
        fputs($fp, "User-Agent: MSIE\r\n");
    }
    fputs($fp, "Connection: close\r\n\r\n");
    if ($method == 'POST') {
        fputs($fp, $data);
    }

    while (!feof($fp)) {
        $buf .= fgets($fp,128);
    }
    fclose($fp);
    return $buf;
}


Problem for me is textarea in a form. How can I send data from textarea to site accordingly to sendtohost function. There are many line in a textarea dividual by enter.

You need to rawurlencode it to include that data in a GET.

By the way, what tutorial or book did you get this code from. Should have had the urlencode or rawurlencode in it already. Fact is that the standard is to ALWAYS urlencode get data but so many of these books omit that.

PS the php functions differ slightly and rawurlencode is what you need in php. It translates non-alphameric data into their asci number eg %20 = a space. You must have seen this in your address bar often.
