Why is there no one?

What is a stupid method?

This requirement can be achieved by splicing filtering conditions, for example, when no conditions exist.

select * from tbl_name where 1=1 

If you select a region, the SQL statement becomes

select * from tbl_name where 1=1 and area = ”XXX“ 

After selecting a method, the SQL statement becomes

select * from tbl_name where 1=1 and area = ”XXX“ and type=1 

Multiple conditions are always placed after the SQL statement.

You can consider passing parameters through the URL, or directly writing a cookie or session, and then assembling an SQL statement for the existing data. I think so, but it depends on the requirements.

No one. Which of the following heroes can help you? thank you.

In fact, this problem is very big, and both the server and client are involved.
The server mainly generates query statements.
How does the client determine the value passing style?
However, if you do not have any specific requirements, why can't you write a book?

Ajax or Frame click to submit once

Like this?
Then you can combine and assemble SQL statements.

I have already written it out, but now it's mainly about data splitting. you can check it at www.0971my.com/wskh.php?

We strongly recommend that you have php + sphinx

I used to get one. you just need to change it.

// Delete the GET parameter if (isset ($ _ GET ['AC']) {$ k = substr ($ _ GET ['AC'], 3 ); unset ($ _ GET ['AC']); if ($ k = 'all') $ _ GET = array (); else unset ($ _ GET [$ k]);}/* GET parameter */function getparam ($ k) {$ param = $ _ GET; if (isset ($ _ GET [$ k]) unset ($ param [$ k]); $ param [$ k] = ''; return http_build_query ($ param );}

This $ param usage, '. $ quyu ['title'].'
The rest is the SQL statement.
