There are at least two ways to do this...
[ol type=\'1\'][*][code]<?php
$q = "select * from messages WHERE id=$id";
$res = mysql_query($q) or die('Problem with query: ' . $q . '<br>' . mysql_error());
$num_msgs = mysql_num_rows($res);
echo num_msgs;  
?>[/code][*][code]<?php
$q = "select count(*) as num_msgs from messages WHERE id=$id";
$res = mysql_query($q) or die('Problem with query: ' . $q . '<br>' . mysql_error());
$rw = mysql_fetch_assoc($res);
echo $rw['num_msgs'];  
?>[/code][/ol]

Can you kindly take a look, I got the function in the correct order of code but know i get a database error, But without the function the code is correct,

What can you see wrong please thank you.

[code]
<?php


$sql_host =   'xxxx';  //add host information here (localhost, mysql.host.com, etc.)
$sql_un   =   'xxxx';  //add your user name here
$sql_pass =   'xxxx';  //add your password here
$sql_db   =   'freedating';  //add your database name here


mysql_connect("$sql_host", "$sql_un", "$sql_pass") or
    die ("Could not connect to database");
mysql_select_db($sql_db) or

    die ("Could not select database");

function counting()
{

$q = "select count(*) as num_msgs from membercomments WHERE id=$id";
$res = mysql_query($q) or die('Problem with query: ' . $q . '<br>' . mysql_error());
$rw = mysql_fetch_assoc($res);
echo $rw['num_msgs'];
}

counting()
?>
[/code]

This is the error i get but only in the function method overwise no error.

[code]
Problem with query: select count(*) as num_msgs from membercomments WHERE id=
You have an error in your SQL syntax. Check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1

I got the function to work but is it the correct way thank you.
[code]
<?php

function counting($count)
{

$sql_host =   'xxxx';  //add host information here (localhost, mysql.host.com, etc.)
$sql_un   =   'xxxx';  //add your user name here
$sql_pass =   'xxxx';  //add your password here
$sql_db   =   'freedating';  //add your database name here


mysql_connect("$sql_host", "$sql_un", "$sql_pass") or
    die ("Could not connect to database");
mysql_select_db($sql_db) or

    die ("Could not select database");



$q = "select count(*) as num_msgs from membercomments WHERE id=$id";
$res = mysql_query($q) or die('Problem with query: ' . $q . '<br>' . mysql_error());
$rw = mysql_fetch_assoc($res);
echo $rw['num_msgs'];
}
