LIMIT query using a variable

Im writing a hack that depending on the number entered in vBOptions, will limit the ammount of TR/TD tags there are using a query. I've tried this code:

PHP Code:


		
			
$uploadcode = $DB_site->query("SELECT uploadcrap FROM portfolio LIMIT $numofportfolio");

Then I use $uploadcode[uploadcrap] in the template
But this only shows one row of code when I entered 5 in options.

Anyone shed some light on this

you shouldn't get a single row, as your using an DB result and not a normal array.

you have to add a whileloop fetch_array afterwards :)

Good idea, I'll try that - thanks

Ok, here is the code i'm using now:

PHP Code:


		
			
$uploadcode = $DB_site->query("SELECT uploadcrap FROM portfolio LIMIT $numofportfolio");

  while($uploadcodes = $DB_site->fetch_array($uploadcode)) {

   eval(" \$codecrap = \" " .gettemplate("codecrap_ap")."\";");

}

Then in the codecrap_ap template, I have $uploadcodes[uploadcrap] but I get an error:

"Warning: mysql_fetch_array supplied argument is not a valid MySQL result resource in db_mysql.php

Any ideas why?

are you sure $numofportfolio is set at least at 1?

also in your eval code you missed a .
