php - Implementing Form that Might Result in Different Queries -

-

i have form needs allow people search hikes, hiking groups, or hikers, depending on radio button choose within form.

obviously, in either of these 3 cases, query of different tables in database, , have different usability down road. shouldn't process of these in 1 place assuming. guys agree?

what might practice way handle such case? tried redirecting request single form processing modules, had trouble making post request in url trying redirect.

ideas/suggestions appreciated, alex

i don't see problem handling 1 form. pass on search type , build appropriate query based on type, search terms, etc. if queries totally different, sounds input gathering pretty simple. may want display results different pages, processing can handled 1 form , 1 script.

quick example:

//get variables out of post  if ($search_type == "hike") {     //put hike query, results     //call script display hikes } elseif ($search_type == "group") {     //put group query, results     //call script display hikes } elseif(...) //etc, etc

(or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

-
example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
