mt_rand()...

They look almost the same...

nrg_alpha · May 6, 2009

Ah yes, I see now.. you meant having <?php ... ?> within the code tag (of which gets colour coded). Got it.

ichimac · May 7, 2009

when I do

var_dump($feed_id);
var_dump($id_rand);

when I do that at the beginning the function runs it gives me int(53) after the function has been run it gives NULL

Ken2k7 · May 7, 2009

Sorry messed up the code while editing. Try again with this please.

<?php 
require_once("includes/session.php");
include('includes/connection.inc.php');
include('includes/corefuncs.php');
$conn = dbConnect('query');
  

$min = 42;
	$max = 118;
	$disallowed = array(117);

function mt_rand_n($min="1",$max,$disallowed) {
    if (!is_array($disallowed)) return false;
    $numbers = array_values(array_diff(range($min,$max),$disallowed));
    if (count($numbers) < 1) return false;
    return $numbers[mt_rand(0,count($numbers) - 1)];
    }

    $id_rand = mt_rand_n($min, $max, $disallowed);
    var_dump($id_rand);
    $sql = "SELECT feed_id,user_nickname,gender,image_normal,user_age,user_location,user_status FROM feed WHERE feed_id='$id_rand' ";
$result = mysql_query($sql) or die(mysql_error());
$row = mysql_fetch_assoc($result);

that's ok I did check it still shows the same.

fuction generation id 98 and the number insert to message for is 0 (zero) when var_dump($sql_comment); echo this back I get this

string(5) "hi 98" string(126) "INSERT INTO journal (carry_user_id, article, created, message_for) VALUES('1', 'hi 98', NOW(),'')"

ps: thanks for sticking whit me on this I'm really grateful

Ken2k7 · May 7, 2009

Well so far so good. What's the other var_dump? Maybe I got confused from your post. I have 3 var_dumps. Can you just lay them out like -

First var_dump = value

Second var_dump = value

Third var_dump = value

Replace value with the value.

Thanks!

ichimac · May 7, 2009

sure

var_dump($id_rand);// ----->int(69) 
var_dump($article); //---nothing at all
var_dump($sql_comment);//--->string(0) "" string(121) "INSERT INTO journal (carry_user_id, article, created, message_for) VALUES('1', '', NOW(),'')" 

//but i change var_dump($article) to var_dump($expected) and print the array
array(4) { [0]=>  string(13) "carry_user_id" [1]=>  string(7) "feed_id" [2]=>  string(7) "article" [3]=>  string(11) "message_for" }

Ken2k7 · May 7, 2009

1. put session_start() at the very top of your script.

2. both $article and $row['feed_id'] are empty? Hmm... so does that mean you didn't type anything in the article field? Under $row = mysql_fetch_assoc($result); can you put -

echo $row['feed_id'];

You can take out all my var_dumps now.

ichimac · May 7, 2009

that is correct I didn't type anything but even if i did the first 3 values are ok just the last one message_for is been a pain...

and when i echo back echo $row['feed_id']; after $row = mysql_fetch_assoc($result);

it shows the same value as $id_rand.

and I'm using session already because in order for the user to leave a message they must register

require_once("includes/session.php");

//this is the code i have if you want to check it out
<?php
session_start();
ob_start();
// set a time limit in minutes
$timelimit = 40 * 90;
// get the current time
$now = time();
// where to redirect if rejected
$redirect = 'http://localhost/main4.php';
// if session variable not set, redirect to login page
if (!isset($_SESSION['authenticated'])) {
  header("Location: $redirect");
    exit;
  }
// if timelimit has expired, destroy session and redirect
elseif ($now > $_SESSION['start'] + $timelimit) {
  // empty the $_SESSION array
  $_SESSION = array();

  // invalidate the session cookie
  if (isset($_COOKIE[session_name()])) {
    setcookie(session_name(), '', time()-86400, '/');
  }
  // end session and redirect with query string
  session_destroy();
  header("Location: {$redirect}?expired=yes");
  exit;
  }
// if it's got this far, it's OK, so update start time
else {
  $_SESSION['start'] = time();
  $mysession = session_id();
  $session_name = $_SESSION['authenticated'];
  $user_id = $_SESSION['user_id'] ;
  }
?>

Ken2k7 · May 7, 2009

Why is that require_once NOT inside a PHP tag?

ichimac · May 7, 2009

because that session.php is another file is just to show you what im using

this are the first few line on the other file msg.php that i posted previously

<?php 
require_once("includes/session.php");
include('includes/connection.inc.php');
include('includes/corefuncs.php');
$conn = dbConnect('query');
