[Resolved] pulling one row from table

[fr8]

i have a mysql database and with a couple tables in it. what i would like to do is pull from one of those tables.

what i would like to do if possible (im not sure still new) is pull one of the rows based on a variable in the url. the variable would be equal to one of the pids from the table rows. is something like this possible with php. if so how ?

Yeah, it's actually pretty easy.

just have an if statement that looks for the variable.

if( !isset($my_var) )
{ echo("You have accessed this page incorrectly, crack head!"); }
else
{
$result = mysql_query("SELECT * FROM table_name WHERE table_id='$my_var'");
$row = mysql_fetch_assoc($result);

i understand all of the code except for the first item.

if( !isset($my_var) )

the "!isset" to be exact.

isset checks to see if the variable has a value. If it hasn't been passed in the query string, them the test returns true (meaning it's not set). If it fails, meaning it exists...
