Passing info through a form submit as opposed to through a URL

[Sootah]

How do you POST data to another script as opposed to having to pass the info through a URL?

I've found this, but I have no idea how to format the vars to post or anything.

Some enlightenment would be lovely.

Thanks in advance. -Sootah

say you have a form field named username

then on the page called by the form you would have to call

$_POST['username'] for that value

so you could do

$username = $_POST['username'];

then $username should have the value entered in the the username field in the form.

Hope this helps.

My PHP script is posting to another script.

Here is my current code:

$text = $_POST["text"];
//str_replace("\r\n",",",$text);
$text = preg_replace('/\r\n/',',',$text);
$text = urlencode($text);

$langpair = urlencode($_POST["langpair"]);
$hl = urlencode($_POST["hl"]);
$ie = urlencode($_POST["ie"]);
$oe = urlencode($_POST["oe"]);

$post_string = 'text='.$text.'&langpair='.$langpair.'&hl='.$hl.'&ie='.$ie.'&oe='.$oe.'&';


$handle = fopen("http://translate.google.com/translate_t?$post_string", "r");

if ($handle) {

   while (!feof($handle)) {

   $buffer = fgets($handle, 4096);



   }

   fclose($handle);

}

$splits=split("<textarea name=q rows=5 cols=45 wrap=PHYSICAL>",$buffer);

   $splits=split("</textarea>",$splits[1]);

$result=$splits[0];

$outputstring = str_replace(",","\r\n",$result);

$outputfile = fopen("output/translated.txt", "w");
fwrite($outputfile, $outputstring);
echo "Finished. File saved at <a href=\"output/translated.txt\">this location</a>";

It grabs a list I provide from my page, passes it to Google's translator, and then grabs the results. The issue is that it passes to the Google translator through URL which severely limits the amount of data that can be passed.

I need my script to post to the translator through a POST itself.

Got er all figured out.

Here's what I came up with:

function HTTP_Post($URL,$data, $referrer="") {

    // parsing the given URL
    $URL_Info=parse_url($URL);

    // Building referrer
    if($referrer=="") // if not given use this script as referrer
      $referrer=$_SERVER["SCRIPT_URI"];

    // making string from $data
    foreach($data as $key=>$value)
      $values[]="$key=".urlencode($value);
    $data_string=implode("&",$values);

    // Find out which port is needed - if not given use standard (=80)
    if(!isset($URL_Info["port"]))
      $URL_Info["port"]=80;


    // building POST-request:
    $request.="POST ".$URL_Info["path"]." HTTP/1.1\n";
    $request.="Host: ".$URL_Info["host"]."\n";
    $request.="Referer: $referrer\n";
    $request.="Content-type: application/x-www-form-urlencoded\n";
    $request.="Content-length: ".strlen($data_string)."\n";
    $request.="Connection: close\n";
    $request.="\n";
    $request.=$data_string."\n";



    $fp = fsockopen($URL_Info["host"],$URL_Info["port"]);
    fputs($fp, $request);
    while(!feof($fp)) {
        $result .= fgets($fp, 128);
    }
    fclose($fp);

    return $result;
}


foreach($_POST as $key=>$value){

if ($key == "text"){
    $value = check_dupes($value);
}
$post_string["$key"] = $value;
}


$output = HTTP_Post("http://translate.google.com/translate_t",$post_string);

// parse gathered data from here

The HTTP_Post function does just that, posts data to another URL.

my check_dupes function merely checks the variable provided for duplicate values.
