Trying to add PHP to my forums

I am trying to add this simple PHP code to scrape the latest currency to my forums. What is the best and easiest way? thanks,

<?php
$today = date('Y-m-d');
$con = mysql_connect('localhost', 'user', 'passwd'); # please put appropriate values here
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("currency", $con); # please replace 'mydb' with your database name.
$query = "SELECT cur_rate FROM currency WHERE cur_date = '$today' AND cur_code = 'PHP'";
$result = mysql_query($query)
or die(mysql_error());
$row = mysql_fetch_array( $result );
$php = $row['cur_rate'];

echo $php;

?>

i tried to write a plugin and used global_start as the hook and it worked one time and then went away and never came back. PLEASE HELP!

also, while i am at it, how would one format the number that it outputs so it is only 2 decimal places?

thanks in advance

Method 1 Including External Files

Method 2 Place the code inside a plugin (no PHP start/end tags), and grab the information into a variable. Do not echo it, just use that variable in a template.

is there a better hook or how would you create a better hook?

i would imagine that if i used global start, it just does it the one time - showing the currency.

any ideas?

thanks.

Plugins don't just disappear. Make sure that you didn't add the plugin in a product that you later uninstalled. Other than that I would recommend Method B, echoing has a tendency not to show up because the template system overwrites all your previous output.

For bugtesting I would make a plugin in global_start (in product vBulletin) that looked something like this:

PHP Code:


		
			
if (isset($_REQUEST['testing'])){
   //Fetch latest Coke prices from coke.com
   getLatestCurrencyCode();

   //350 litres gives you 2 gold coins.
   echo $CokeToGoldRatio;

   //Make sure that we don't let vBulletin continue
   //(to prevent the template from writing over your echo)
   exit;
}

What do you mean that it worked just one time? You mean only the first time you hit the site? First time you hit that page? I don't understand what you mean.

yes. i finally got it to work. it showed the currency. i refreshed and it was gone! :(

so i thought it was the hook - global_start - like it will deal with global commands but just on the start or one time. it is my first plugin attempt.

not sure what i am doing.

could someone walk me through the whole thing? that wud be even better. maybe there is a better vbulletin hook to use than global_start? not sure.

thanks.

Post your exact plugin code, please, and your template edit (a few lines above and below and tell us what template it is).

original code is this:

<?php
$today = date('Y-m-d');
$con = mysql_connect('localhost', 'username', 'passwd1'); # please put appropriate values here
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("dbname_currency", $con); # please replace 'mydb' with your database name.
$query = "SELECT cur_rate FROM currency WHERE cur_date = '$today' AND cur_code = 'PHP'";
$result = mysql_query($query)
or die(mysql_error());
$row = mysql_fetch_array( $result );
$php = $row['cur_rate'];

echo "1 USD = PHP $php";?>

//end orignal code

i set up a plugin called currency using vbulletin and global_start and did this:

$today = date('Y-m-d');
$con = mysql_connect('localhost', 'username', 'passwd1');
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("dbname_currency", $con);
$query = "SELECT cur_rate FROM currency WHERE cur_date = '$today' AND cur_code = 'PHP'";
$result = mysql_query($query)
or die(mysql_error());
$row = mysql_fetch_array($result);
$php = $row['cur_rate'];

then i save this as currency (plugin)

and then go to the header to insert the information i wanted:

echo "1 USD = PHP $php";

what am i doing wrong?

thanks.

Please use the html/php tags. It is very difficult to read code when you don't use those.

Don't use echo. Put the variable into the template or use a template_hook. Also, it is probably not a good idea to use a variable named $php.

and then the plugin using vbulletin and global_start

$today = date('Y-m-d');
$con = mysql_connect('localhost', 'username', 'passwd1'); # please put appropriate values here
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("dbname_currency", $con); # please replace 'mydb' with your database name.
$query = "SELECT cur_rate FROM currency WHERE cur_date = '$today' AND cur_code = 'PHP'";
$result = mysql_query($query)
or die(mysql_error());
$row = mysql_fetch_array( $result );
$php = $row['cur_rate'];

then in the header:
echo "1 USD = PHP $php

$php is scraping philippine peso and is standard at yahoo for that currency so i cannot change it unfortunately.

is this what you wanted?

can you help me now?
