You've got to build up the query statement field by field.
- Start with SELECT * FROM table WHERE
- That the condition (like VAR_X = '$VAR_X') for filled fields only.
- The one detail to note: for all but the first condition add AND before.
So if only var_1 and var_7 are filled the result would be
SELECT * FROM tabel WHERE var_1 = '$var_1' AND var_7 = '$var_7'.
So I'm very new to all this and I'm trying to build a website based on a MySQL database. I want to make a page that has a bunch of different attributes you can search by. The way it's set up now if you don't fill out a certain criteria it only turns up entries where that criteria is blank. I want it to show all of the rows where the other columns match, ignoring the blank one. Here's what I'm doing now:
$result = mysql_query("SELECT * FROM table
$var_1, $var_2, and $var_3 all come from an html form, and if certain fields aren't filled in they're left blank and respond to if... statement where $var_1=='' When I only had 4 of them I made one for each of the 16 possible combinations, but now I want to double that so it's time to figure out a better way. I've been searching for a couple hours but it seems like I don't know enough about MySQL to know what to look for. I just copied what I have now from a tutorial. Anyone one to help point me in the right direction? Thanks in advance!
