populating of drop down menu not working


stockychaser

Recommended Posts

trying to get a drop-down menu (in a form) to work  that needs to get populated from a table

table called  :  CarCategory

in this table are 2 columns  called

CarCategoryID    (unique number from 1-18)

CarCategoryDesc  (actual name of category.. e.g. 'convertible')

 

link :  http://98.131.37.90/postPart.php

 

I'm a total novice.. and can't figure out why the first is not working and the second (country) is working

 

 

code :

 

<!--NOT WORKING ... why not ?? should show drop down menu--> 

    <label>

      <div align="center">

          <select name="carcategory" id="CarCategory" class="validate[required]" style="width: 200px;">

 

          <option value="">Select Car Category from list...</option>

 

            <?php while($obj_queryCarCategory = mysql_fetch_object($result_queryCarCategory)) { ?>

                <option value="<?php echo $obj_queryCarCategory->CarCategoryID;?>"

                <?php if($obj_queryCarCategory->CarCategoryID == $UserCountry) { echo 'selected="selected"'; } ?> >

                <?php echo $obj_queryCarCategory->CarCategoryDesc;?></option>

            <?php } ?>

 

        </select>

      </div>

    </label>

 

<!-- working ! -->

    <label>

      <div align="center">

          <select name="country" id="Country" class="validate[required]" style="width: 200px;">

 

          <option value="">Select...</option>

 

            <?php while($obj_queryCountry = mysql_fetch_object($result_queryCountry)) { ?>

                <option value="<?php echo $obj_queryCountry->CountryID;?>"

                <?php if($obj_queryCountry->CountryID == $UserCountry) { echo 'selected="selected"'; } ?> >

                <?php echo $obj_queryCountry->CountryName;?></option>

            <?php } ?>

 

        </select>

      </div>

    </label>

Hi stockychaser,

I can't see the country drop-down in the page you link to. Are you definitely getting a connection to your database?

Try putting some debugging code in to see if you are getting any results.

 

Use var_dump() to view the content of $obj_queryCarCategory

 

 <?php while($obj_queryCarCategory = mysql_fetch_object($result_queryCarCategory)) { var_dump($obj_queryCarCategory); ?>

 

Can you post the code that does the database connection and query?

 

Cheers,

Fergal

hi Fergal,

the connection looks like this :

 

<?php

 

    // information about Mysql server

    $dbhost = '98.130.0.104';

    $dbuser = 'soundfa_sam';

    $dbpass = '********';      //here sits the correct password !

    $dbname = 'soundfa_acn';

 

    // try to connect

    $conn = mysql_connect($dbhost, $dbuser, $dbpass) or die (mysql_error());

 

    // choose database

    mysql_select_db($dbname);

?>

 

 

- - - - -

 

When I insert the php string you gave me above, the page no longer loads.

is this normal ? (again... I'm totally new to PHP !! (sorry))

 

thanks all !

Hi stockychaser,

Your connection code looks fine.

 

If you're getting a blank page it is probably because error reporting is turned off. Try inserting this at the top of your script:

 

error_reporting(E_ALL);
ini_set('display_errors','On');

 

If you have direct access to the database  try running your SQL query directly to make sure it doesn't contain any errors.

It's working. .

 

at the top of the page... I forgot to put in the "getCarCategory" section :(

 

 

 

<?php

    // start session

    session_start();

 

    // Include site's config

    include_once 'phpcodes/config.php';

 

    // Include connection

    include_once 'phpcodes/conn.php';

 

    // get Currency

    $sql_queryCurrency = 'SELECT * FROM Currency';

    $result_queryCurrency = mysql_query($sql_queryCurrency) or die (mysql_error());

 

    // get CarMake

    $sql_queryCarMake = 'SELECT * FROM CarMake';

    $result_queryCarMake = mysql_query($sql_queryCarMake) or die (mysql_error());

 

    // get CarCategory

    $sql_queryCarCategory = 'SELECT * FROM CarCategory';

    $result_queryCarCategory = mysql_query($sql_queryCarCategory) or die (mysql_error());

 

    // get CarModel

    $sql_queryCarModel = 'SELECT * FROM CarModel';

    $result_queryCarModel = mysql_query($sql_queryCarModel) or die (mysql_error());

 

 

?>

 

 

thanks for all the help...
