I can't see nothing with these codes why?

[bilis_money]

it works but i can't see the results or record?
after the query,

the codes,
[code]
<?php
//search record for topic records.
session_start();
require_once ("opendb.php");
require_once ("error_messages.php");
$COerr_msgs = new error_messages; //instantiate object

//get variables from form
$topic_new = $_POST['topic'];
$_SESSION['topic']=$topic_new;

//select record
$query  = "SELECT * FROM topics WHERE title='$topic_new'"; //get record from table
$result = mysql_query($query);
$chk_dup = mysql_fetch_array($result);

//retrieving old title
$title_old = $chk_dup[title]; //fetch from table
$descrip_old = $chk_dup[description];
$url_old = $chk_dup[url];


//compare and search new_topic with old_topic using REGEX
if(preg_match("/\b$topic_new\b/i", $title_old)) {
//display all data records using paging.
echo "ok match found!<br>";
echo $title_old, "<br>";
echo $descrip_old, "<br>";
echo $url_old;
} else {
$COerr_msgs->err_msgs('search1');
}
?>
[/code]

i'm just wondering if my preg_match() here works fine?

[code]if(preg_match("/\b$topic_new\b/i", $title_old))[/code]

specially the insertion of the $topic_new inside preg_match and
$title_old?

any good advice?


GOD bless u for your hep in advance.

Well, what do you see? How do you know it works?

[bilis_money]

what i mean works, is i don't see any error.
but after the execution it is showing nothing just PLAIN WHITE WEB PAGE.

no error, no messages, no output result, nothing?

any nice guess from you guys?

Try:

[code]
<?php
//search record for topic records.
session_start();
require_once ("opendb.php");
require_once ("error_messages.php");
$COerr_msgs = new error_messages; //instantiate object

//get variables from form
$topic_new = $_POST['topic'];
$_SESSION['topic']=$topic_new;

//select record
$query  = "SELECT * FROM topics WHERE title='$topic_new'"; //get record from table
        $result = mysql_query($query) or die(mysql_error());

//retrieving old title
while ($chk_dup = mysql_fetch_array($result)) {
$title_old = $chk_dup["title"]; //fetch from table
$descrip_old = $chk_dup["description"];
$url_old = $chk_dup["url"];
}


//compare and search new_topic with old_topic using REGEX
if(preg_match("/\b$topic_new\b/i", $title_old)) {
//display all data records using paging.
echo "ok match found!<br>";
echo $title_old, "<br>";
echo $descrip_old, "<br>";
echo $url_old;
} else {
$COerr_msgs->err_msgs('search1');
}
?>
[/code]
