result.php has to do 4 main tasks

prepare the input for DB query
query the DB
prepare the DB results for display
display the results

1.1) get the data from $_GET or $_POST (haven’t seen the opening <form>).
1.2) remove the unnecessary values
1.3) sanitize against SQL Injection. how you do that exactly depends on your DB system (Database Abstraction Layer, if you have one)
2) run the query
3) this again depends strongly on your DB system (results from a PDO based system differ quite much from a simple mysql_query())
4) print the values where you want them to be.

notes:
your file is neither valid XHTML nor is it ever treated as XHTML.
CSS helps you building cleaner and smaller HTML code.

thank you your answer Dormilich!!

about cleaning the file with CSS ... is what i,m doing right now... what you see at the moment is only for you helping me. this way you can see what i want to do.

Now time to jump in the CORE of the subject..

let me know what information you need to help me with the code for my result.php file.

i need to get any selection made the user in the dropdown and after that searchg the database for every matching item and after display the result.

can you gave me a hint of code that can do this. i'm using a normal mysql database nothing fancy.

this site is not for purchasing something. this is only a BIG library of everything made in 1/24 - 1/25 scale.

you can check the main page www.scale24-25.com i explain a bit more what it will do.

but for now i have to made some coding and it's whwere i have some problem

thank's in advance for your help

mainly how you want to do it, what you require, basic coding stuff.

first you need to decide, how you want to interact with your DB. from personal experience I can recommend a “Database Abstraction Layer”* (like PHP’s PDO and MySQLi classes). You should also consider using a “PHP framework”* (e.g. CodeIgniter), so you don’t have to code everything by yourself (and making DB queries is quite a common task). Once you decided about that we can talk about preparing data.

@scaleautostyle
two possible routes are
1) fetching all the requested data and process that in a loop
2) fetching the matching DB keys and do fetch & display **

@scaleautostyle
I can give you an example of code I use, but that won’t help you much.

* google search term
** this can save considerable amount of code + way more flexible

thank's for the reply Dormilich!!

i just download CodeIgniter.. that's sound great for a beginner.. but i have a problem.. it's the first it's happen and i don't know what to do.

when i open the index.php file in my browser ( using my localhost) a pop-up appear to log in my localhost. it's asking my username and password.. what's this???

also i will do what you think it will be the best for the purpose of the site i'm building. do you see the update page www.scale24-25.com/kitDB-site.php it's a bit better,

so let me know about the popup login i got and by what you want to start.

i will e a VERY GOOD student sir. promise.

thank's

beats me why… no idea. check your server directory for a .htaccess file (this is used on apache for a login pop-up). on all posix os this is a hidden file!

@scaleautostyle
it’s not about what I think… it looks way better now :)

well, as for the HTML, get rid of the table, it’s not necessary.
and drop XHTML, if you don’t want to use the possibilities of using XML

Aug 25 '09 #7

WOU ouuu... it's working... i found the .htaccess file and delete it... now it's working..

what do you mean by rid the XHTML... i wrote my code using adobe dreamweaver selecting new PHP and open. i don't use XHTML

what do you mean by this??

well, as for the HTML, get rid of the table, it’s not necessary.

do you mean to use CSS instead of what i use??

and now i'm ready to sstrat... hum hum.. by what we begin proffessor??

thank's

@scaleautostyle
you (Dreamweaver resp.) use a XHTML 1.0 DTD… use this instead

Expand|Select|Wrap|Line Numbers

 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN"

        "http://www.w3.org/TR/html4/strict.dtd">

@scaleautostyle
CSS is a layout language. so if you have semantic (structural) html code, you can use CSS to make it look like you want it. (see CSS Zen Garden, always the same HTML, but each CSS brings a totally new appearance)

ex. full code

Expand|Select|Wrap|Line Numbers

             <ol id="all_params">

                <li>

                    <label for="limit_l">Intervall von:</label>

                    <input  id="limit_l" type="text" size="20" value="0" />

                </li>

                <li>

                    <label for="limit_r">Intervall bis: </label>

                    <input  id="limit_r" type="text" size="20" value="1" />

                </li>

           </ol>

Expand|Select|Wrap|Line Numbers

 ol {

    list-style-type: none;

}
 
li label {

    float: left;

    width: 10em;

    text-align: right;

    padding-right: 0.5em;

}
 
li {

    clear: both;

    padding-top: 0.5em;

}

thank's for the hint about the xhtml.. i will change all my file.

for the CSS i'm working on that already. when it will be finish i will let you know.

well, well, my dear pupil… ;)

this is indeed not an easy decision to make (for I’m not an SQL expert).

I guess you have to construct the SQL string according to the options on which you refine (you could in theory fetch all IDs which match each option separately and only use these that occur in every result set, but this is not good if you have huge data sets).
… looks like a reasonable way to go.

of course you should read CodeIgniter’s MySQL section (if you use CI). this should clear the matter, how you connect & query (mostly)

Aug 26 '09 #11

connecting to the database is not a problem. i don't understand how i can get the result. if you or somebody put a simple code on how to do base on my need.. ( with my field and file) it will be appreciate

ex: if someone click on the 1/24 from the scale drop down and click submit. what's the code need to return all the 1/24 found in the table kit field scale.

if he select tamiya from the manufacturer kit dropdown and honda from the reel manufacturer dropdown and then click the submit button.. what will be the code to return the info from the table kit field manufacturer_kit and manufacturer_reel.

all my code can be found in the post above. base on this file what i have to change to work. may be i have to change some variable or other things. i read, read, and RE-read. but it look like if i ask you to read an instruction in chinese. you will read 100 time but never understand. except if i gave a traduction of a small text you will be able to compare the instruction with my text and so..

i hope someone can help me i really need an answer for my problem

my problem here is, that I don’t know the CI mysql syntax.

@scaleautostyle

Expand|Select|Wrap|Line Numbers

 -- as a prepared statement

SELECT `kit_id` FROM table_name WHERE `scale` = ?

then you can use another prepared statement to fetch all the data

Expand|Select|Wrap|Line Numbers

 -- SQL

SELECT * FROM table_name WHERE `kit_id` = ?
 
# PHP

foreach ($id_array as $id)

{

  // pseudo code, use CI’s syntax instead

  $pdos->execute(array(1 => $id))

  printResult($pdos->fetch());

}

@scaleautostyle

Expand|Select|Wrap|Line Numbers

 -- as a prepared statement

-- get 20 results from offset

SELECT `kit_id` FROM table_name WHERE `manufacturer_kit` = ? AND `manufacturer_reel` = ? LIMIT ?,20
 
# PHP (again, mostly pseudo code)

$pdos->execute(array(1 => "tamiya", 2 => "honda", 3 => 0));

$id_array = $pdos->fetchAll();

the output code is the same as above

Aug 26 '09 #13

still get the #$#%$% problem this is the link of the page

http://www.scale24-25.com/kitDB-site.php

for this page NO PROBLEM.. here it is... when you clic on the go button it supposed to return what the user select in the field. ex: you choose 1/24 and honda. a query will search the database under the column scale to find every 1/24 and under the constructor name to find all honda and them display the result.

this query have to be made in a separate files name kitDB-result.php.

but i REALY don't know what the query need to be.

if you can gave me an exemple of the query using my data it will be appreciate

yours

sebastien

PS: use this.

database name: sebastien
username: SAS
password: resinkit

sale column = scale
kit manufacturer = kit_manufacturer
engine = engine

thanks in advance

Did you try the SQL statement that Dormilich suggested?
It looks "right" to me too, mind you I'm not a SQL expert...

Whenever I get stuck on SQL stuff I turn to my trusty database book or the w3cschools site. The W3CSchools site has examples on the Select Statement and the Where Clause that may help you get an idea of what you need to do....

SELECT `kit_id` FROM table_name WHERE `manufacturer_kit` = ? AND `manufacturer_reel` = ?

This is a simple select statement. It should work no problem. Be aware however that you need to replace the ? with actual data. If that select gets the data you want then you can start to LIMIT the output and order it and do all sorts of fancy things. Just get the basic SQL down first.

The only problem is that you are selecting only one field of data "kit_id" if you want everything from the whole table "table_name" you would change kit_id to *.

Sep 17 '09 #16

@RedSon

ok but how I can replace the ? by the selection of the user....

 mysql_query( "

    SELECT kit_id

    FROM table_name

    WHERE manufacturer_kit='$manufacturer_kit' AND manufacturer_reel='$manufacturer_reel'

    LIMIT 1

" );

Obviously you will need to define your $manufacturer_kit and $manufacturer_reel variables. I made a string using " so that php variable can be included, and then I wrapped the variables in ' so that MySQL is happy. You could also have a multipart string, but that is easier. I also added a LIMIT 1, so that only one record is returned, and it stops searching after it gets that one. Look it up if you haven't used it before.

@RedSon
You’ve got the intention wrong. this is not a simple SELECT statement to display the results, it is a SELECT statement for use as Prepared Statement. the "?" will be replaced in the execute() call. further this statement only fetches the kit_id, because for the result display, there will be used another Prepared Statement, which uses the selected IDs to get the complete data.
