In my page, there are multiple $_GET values. ie
if(isset($_GET["projects"]))
{ ..... }
else if(isset($_GET["research"]))
{ ...... }
else if(isset($_GET["publication"]))
{ ..... }
...upto 10 elseif's
Can I shorten this? Can I get these values {projects,research, publication,..} in a variable.?
Ok so I guess I figured out what you want from your comments. Lets see.
$types = array('projects', 'research', 'publication'); // add as many as you want
$valid = array_intersect_key($_GET, array_flip($types));
if (count($valid) > 1)
die "More than one category is set, this is invalid.";
if (!$valid)
die "No category was set, you must choose one.";
foreach ($valid as $type => $value) // just to split this one element array key/value into distinct variables
{
$value = mysql_real_escape_string($value); // assuming you are using mysql_*
$sql = "SELECT * FROM table WHERE $type = '$value'";
}
