3 Queries at once...HOW TO DO THIS????

[jwwceo]

I have a master search box on my site that I want to do a bunch of things when submitted. Basically, I want customers to be able to enter anything in there..like keywords and colors and have the query look in a bunch of different places for matches.  I already have these 2 queries running, that search for kewywords and colors, but I'd like them to both be run when a customer inputs the search box. I'd also like it to query the item name and the notes field. The third query is displayed below but I'm not sure of the syntax on it...

At any rate... how can these three be combined to one varible that I can run in a while loop to display products on my page...I also only need one entry per item (shirt_id)...in case numerous fields match the search string...

mysql_query("SELECT * FROM shirtcolors
  LEFT JOIN colors ON shirtcolors.color_id = colors.color_id
  LEFT JOIN shirts ON shirtcolors.shirt_id = shirts.shirt_id
  WHERE color = '$colorsearch' ORDER BY shirts.$field $direction") or die(mysql_error());

mysql_query("SELECT * FROM shirtkeywords
    LEFT JOIN keywords ON shirtkeywords.keyword_id = keywords.keyword_id
    LEFT JOIN shirts ON shirtkeywords.shirt_id = shirts.shirt_id
  WHERE keyword = '$keywordsearch'  ORDER BY $field $direction") or die(mysql_error());

mysql_query("SELECT * FROM shirts WHERE notes like'%$search%' OR name like'%$search%'") or die(mysql_error());

Store the results of each query in an array: $arr1, $arr2, $arr3, etc.

Each array is basically a set, so we take the UNION of any two minus their INTERSECTION.

$Result = array_merge( $arr1, array_diff($arr2, $arr1) );
$Result = array_merge( $Result, array_diff($arr3, $Result) );

Perhaps there is a better way, but that should do the trick.

[code]mysql_query("query 1; query2; query 3;");[/code]

If you don't understand what I mean, then I mean that you just have to seperate the queries with semi-colons ( [tt];[/tt] ).

The mysql_query documentation says the query should not end with a semicolon.  I've not tried submitting multiple queries in that way, but would that return all of the results in a single result set?
