PHP - Moved: How To Submit The Value Of Drop-down Selection Without Actually Clicking On Subm

Hi All,

I have 2 tables:

one
CarMake
- CarMakeID
- CarMakeDesc

two
CarModel
- CarModelID
- CarModelMake
- CarModelDesc

Depending on what the user selects in the first dropdown (carmake)
the possible selection in the second dropdown (model) needs to be limited to only the models from the selected carmake.
in the second table (Carmodel : the 'CarModelMake' = CarMakeID, to identify the make)

How do I limit the dropdown 'CarModel' based on the selected CarMake in the first dropdown.

link :    http://98.131.37.90/postCar.php


code :
-- -- --
Code: [Select]



<label>
            <select name="carmake" id="CarMake" class="validate[required]" style="width: 200px;">

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

            <?php while($obj_queryCarMake = mysql_fetch_object($result_queryCarMake)) { ?>
                <option value="<?php echo $obj_queryCarMake->CarMakeID;?>"
                <?php if($obj_queryCarMake->CarMakeID == $CarAdCarMake) { echo 'selected="selected"'; } ?> >
                <?php echo $obj_queryCarMake->CarMakeDesc;?></option>
            <?php } ?>

        </select>
</label>

        <label>
<select name="carmodel" id="CarModel" class="validate[required]" style="width: 200px;">

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

            <?php while($obj_queryCarModel = mysql_fetch_object($result_queryCarModel)) { ?>
                <option value="<?php echo $obj_queryCarModel->CarModelID;?>"
                <?php if($obj_queryCarModel->CarmodelID == $CarAdCarModel) { echo 'selected="selected"'; } ?> >
                <?php echo $obj_queryCarModel->CarModelDesc;?></option>
            <?php } ?>

        </select>
</label>



I'm a novice.. and appreciates all the help !

I am creating a form that will allow the user to select the make of vehicle "FORD" for example. If that make of vehicle is selected among different makes of vehicles, then another box will appear, with all the models for that particular model "Fiesta" for example.

What type of code accomplishes this setup in my web page? I do not want to list 500 models in one drop down list, but just those for each make in the first drop down list.

Thanks much!

guys i have this  dropdown menu

echo "<form method=\"post\" action=\"\">";

echo "<center><select name=\"mydropdown\" size=\"0\" style=\"height:4em; width:15em;\">";

echo "<option value=\"Milk1\">{$_SESSION['tem1']}</option>";
echo "<option value=\"Milk2\">{$_SESSION['tem2']}</option>";
echo "<option value=\"Milk3\">{$_SESSION['tem3']}</option>";

echo "</select></center>";
echo "</form>";

and i wand to update a variable every time i select one of the contents...


how can i done this???

If I have a drop-down list...
Code: [Select]
<select name="attendees">
                        <option value="">--</option>
                        <option value="1">1</option>
                        <option value="2">2</option>
                        <option value="3">3</option>
                        <option value="4">4</option>
                    </select>


Where does the value that the user selects get stored?


Does it get stored in $_POST by default (if a Form is used)?

What variable would hold the selected value?

I am trying to make a Web Form for people to fill out that has two drop down menus where i want the first drop down menu's selection changes the values of the selections in the second drop down. ((IE. If the first drop down value is "product 01" then the second drop down shows values "Red, Green, Blue" while if the first drop down value is "product 02" then the second drop down shows values "Yellow, Green"))
Anyone have any ideas? Thanks in Advance.

day VARCHAR( 2 ) NOT NULL ,

year VARCHAR( 4 ) NOT NULL ,
is this correct?

many thanks

Hello,
i want to reproduce a content switcher based on drop-down menu (example: http://www.infocercetare.ro/index.php) anyone can help me with the logic of the function the rest i think i can handle.

best regards

Need some help to define the php logic to echo back a selection if/when chosen from the drop down menu.
Note: I'm using just a small subset of the USA states to show setup and what I'm trying to accomplish - it will be the same for all the other drop down menus as well....

Here's the example code:

Code: [Select]

<form name="form1" method="post" action="<?php $_SERVER[PHP_SELF]; ?>">
<select name="address_state" id="address_state" tabindex="25">
<option value="" selected> - Select State -</option>
<option value="AK">Alaska</option>
<option value="AL">Alabama</option>
<option value="AR">Arkansas</option>
<option value="AZ">Arizona</option>
<option value="CA">California</option>
<option value="CO">Colorado</option>
<option value="CT">Connecticut</option>
<option value="DC">District of Columbia</option>
</select>

<input name="submit" type="submit" value="submit" tabindex="900" id="submit" />
</form>

Issue: I have validation (logic) define to check all the (other) text, radio, and check boxes of the form and that all works great! However, any time one of those particular fields fail validation, any selected "drop down" item is lost - it defaults back to no selection and the user has to make all drop down menu selections again.

Can someone provide method to echo back - in php being the page reloads to itself - the drop down selection as in the example above?
Thanks!

Hello.

I hope one of the PHP/HTML gurus here can help me. I have a web page that has been altered a bit to add some Google Analytics stuff and I've moved it to a 2nd directory. The original one works fine, the 2nd one won't post the form when I click the submit button.

1st URL https://www.theneutralizer.info/neutralizer
2nd URL: https://www.theneutralizer.info/neutralizer2

I have changed the action property to the correct script, and it does exist. But the problem is when clicking the button nothing happens.

Anyone have any ideas? I can send the PHP code if needed, but since it's HTML output, it should work the way it is displayed in the browser.

My problem is when the entries in the form are validated and some fields with incorrect entries are found the fields filled out stay on the re-load of the form, all of them except the US States drop down menu which reverts back to Alabama every time.

I would like to see that the user selection stays in place even after a re-load of the form. and with my limited experience I am having an issue trying to figure this out for a school project.

Any help at all would be greatly appreciated, like what variables to create/call on and where exactly I insert this code.

Much appreciated.

I'm trying to repopulate a dropdown list when the user hits the submit button to add another item to the dropdown.

I'm trying to use the isset method, but am having some issues implementing it properly. Can anyone steer me in the right direction?

Hi all

I am trying to write a piece of code that allows a user to select a country from the drop down menu and them submit it so that it changes the delivery cost in the session.

Here's the code for the drop down menu:

echo "<form method=\"post\" action=\"basket.php\">";

                     echo "<select name=\"postal_area_name\" >";

                        echo "<option value=\"\">--Please Select--</option>";

                        echo "<option value=\"England\">England</option><option value=\"Scotland\">Scotland</option><option value=\"Wales\">Wales</option>";

                     echo "</select>";

                     echo "<input type=\"submit\" name=\"submit_postal_area\" value=\"Go\" class=\"go\">";

                     echo "</form>";

Then here's my code to grab the delivery change from the form:

if(isset($_POST['postal_area_name'])) {

         $_SESSION['postal_area'] = ($_POST['postal_area_name']);

         header("Location: basket.php");

         exit;

      }

Then this is to set the session price:

if(isset($_SESSION['postal_area']) && $_SESSION['postal_area'] == "England") {
                        $set_delivery = "5.95";
                     } elseif(isset($_SESSION['postal_area']) && $_SESSION['postal_area'] == "Wales") {
                        $set_delivery = "10.00";
                     } elseif(isset($_SESSION['postal_area']) && $_SESSION['postal_area'] == "Scotland") {
                        $set_delivery = "20.00";
                     } else {
                        $set_delivery = "5.95";
                     }
   
                     $subtotal += $set_price * $qty;
                     $delivery += $set_delivery * $qty;

Then I echo out the $delivery in the basket.

This doesn't seem to update, it shows the value as being 0 all the time?

Please help

Thanks
Pete
