First of all: this is NOT a php list.
Second: just construct the sql query by iterrating though the argument list with a
foreach statement.
$searchgenre="punk, hardcore, ...";
if(!($genre_array=split(", ",$searchgenre))){
print "Error...";
}
//assumes you have at least one genre
$first_genre=array_shift($genre_array);
$query="select * from artists where genre like '%$first_genre%'";
foreach($genre_array as $another_genre){
$query.=" OR '%$another_genre%'";
}
$query.=" ORDER BY artist";
The only drawback could be that you must have php4 to have the foreach construct. But
even with php3 use a while loop to go through the genre list.
