Advanced Search - customized product fields?

[zvenson]

well somehow i figured it out but get a strange error...

the search can be expanded to custom tables by adding this to your
/include/modules/pages/advanced_search_results/header_php.php

- assuming you have a field called extras_flammability_test

if (isset($_GET['extras_flammability_test'])) {

$extras_flammability_test = $_GET['extras_flammability_test'];

}

then in the $define_list = array
i added something like

'PRODUCT_EXTRAS_FLAMMABILITY_TEST' => PRODUCT_EXTRAS_FLAMMABILITY_TEST,

in the query i added

LEFT JOIN " . TABLE_PRODUCTS_EXTRA_STUFF. " pu

ON pu.products_id= p2c.products_id

and did some other minor changes to the file. The search performs and gets the products where the criteria are matching, but somehow on every result i get there are 4 buttons to add the product to the shopping cart - i m looking at it for quite a time now but cannot find out what went wrong - has anyone a hint or point my stupid face to it so i can find the problem? thank you -
the advanced search can be found here
(the page is under developement right now and there are only test products included but for testing purposes it should be okay)

thanks for help!

[zvenson]

okay found the problem - often it just helps to write it down and ask in the forums and then give the answer to it myself
if anyone is interested in the solution let me know

It is always helpful if you post the solution to any problem, even if you do work it out for yourself, so that others can be helped by your discoveries ...

yeah - that`s what i want to do but ran into antother problem

i want to select a value "class_of_absorbtion" which can be in three different tables (for each product). This value can be in one, two or three or neither of the tables. I have and sql statement like this:

WHERE (p.products_status = 1 AND p.products_id = pd.products_id AND pd.language_id = 1 AND p.products_id = p2c.products_id AND p.products_id = pu.products_id AND p.products_id = pac.products_id AND p.products_id = puc.products_id AND p.products_id = pic.products_id AND p2c.categories_id = c.categories_id AND (pac.class_of_absorbtion OR puc.class_of_absorbtion_second OR pic.class_of_absorbtion_third) ='B'

so there are three tables of class_of_absorbtion. Im confused about the OR and AND statement - my code doesn`t work so maybe i have again something wrong in my php or even in my logic.
If anyone could have a quick look at this would be very nice!
thank you!

[zvenson]

no one helping? what a bummer....

[zvenson]

Hi!
I`m really stuck over here so if anyone could help me that would be sooooooooo nice...
I'm trying to explain my problem again:

I have 3 Tables called:
products_acoustics
products_acoustics_second
products_acoustics_third

each table contains a field products_id and a field for the acoustics information which can be values from A to E.
the three fields for the acoustics information are called
class_of_absorbtion (for table products_acoustics)
class_of_absorbtion_second (for table products_acoustics_second)
class_of_absorbtion_third (for table products_acoustics_third)

so i think i need to "left join" these tables together so i can get the coresponding product with just one "where" clause, right?

I tried the following (from clause)

$from_str = "FROM (" . TABLE_PRODUCTS . " p

LEFT JOIN " . TABLE_MANUFACTURERS . " m

USING(manufacturers_id), " . TABLE_PRODUCTS_DESCRIPTION . " pd, " . TABLE_CATEGORIES . " c, " . TABLE_PRODUCTS_TO_CATEGORIES . " p2c )

LEFT JOIN " . TABLE_PRODUCTS_EXTRA_STUFF. " pu

ON pu.products_id= p2c.products_id


LEFT JOIN " . TABLE_PRODUCTS_ACOUSTICS. " pac
ON pac.products_id = p2c.products_id
LEFT JOIN " . TABLE_PRODUCTS_ACOUSTICS_SECOND. " puc
ON pac.products_id = puc.products_id
LEFT JOIN " . TABLE_PRODUCTS_ACOUSTICS_THIRD. " pic
ON pac.products_id = pic.products_id


LEFT JOIN " . TABLE_META_TAGS_PRODUCTS_DESCRIPTION . " mtpd

ON mtpd.products_id= p2c.products_id

AND mtpd.language_id = :languagesID";



$from_str = $db->bindVars($from_str, ':languagesID', $_SESSION['languages_id'], 'integer');

and here the where clause

if (isset($_GET['class_of_absorbtion']) && zen_not_null($_GET['class_of_absorbtion'])) {

$where_str .= " AND (pac.class_of_absorbtion
OR puc.class_of_absorbtion_second
OR pic.class_of_absorbtion_third) = :absoID";
$where_str = $db->bindVars($where_str, ':absoID', $_GET['class_of_absorbtion'], 'string');


}

I know i must have gotten something wrong, because still only the first table "class_of_absorbtion" and the field "class_of_absorbtion" is searched. If anyone could help me a little on this, would be sooo nice. Hope anyone does. Thank you!

[zvenson]

well now i solved it - was just a tiny little thing, but if no one helps these things are sometimes hard to find

here`s the code for the correct where clause

 $where_str .= " AND (pac.class_of_absorbtion=:absoID
 OR puc.class_of_absorbtion_second=:absoID
OR pic.class_of_absorbtion_third=:absoID)";

Sorry Zvenson,

you are right. That's the situation in advanced search:

- if I leave the search field "keywords" blank and i fill only the new search field with an author name (it is supposed to search in my new field "author"), zen cart tell me "You must fill at least one field of research"

- if i fill "keywords" with a word and the new field with an author name, zencart gives me back only the products that match the first criteria

So, Zenky seems to ignore my second search field...

[zvenson]

Hi Marco!
Well, my first thought is, that there must be something wrong in this line where you put this:
&& empty($products_author)
this line should check if the author (or any other field) is empty and if so - you get the error message that nothing has been entered. Well - the reason for this could be, that the "$products_author" variable is empty - try inserting an

echo $products_author;

above the line where all the "&& emptys" are - then enter a search word in the products author field - do a search and look if the $produts_author is "echoed" (printed) somewhere on your screen. if it is not - then there must be something wrong bevor the actuall search is done...
Hope this again helps a little!

I'm now following this thread for my own reasons! I have added a new table of product details (e) instead of adding to the product table. All of possible search fields are boolean - either 1 or 0 which is served by checkboxes on the search form.

So looking at your code suggestion above,
1) (isset($_GET['dwarf']) && !is_numeric($_GET['dwarf'])) &&
2) && empty($dwarf)
3) case 'dwarf':
$select_column_list .= 'e.dwarf';
4) if (isset($_GET['dwarf']) && zen_not_null($_GET['dwarf'])) {
$where_str .= " AND e.dwarf = :dwarf";
$where_str = $db->bindVars($where_str, ':dwarf', $_GET['dwarf'], 'string');
}

this doesn't work - and I know the field isn't a string as in number 4.

When I say it doesn't work - the search page just refreshed itself and never goes to the results page.

I'm pretty sure I've got the table added correctly to the select statement and even if I didn't, I'm not getting that far!

What might be wrong?
