two dropdownlist - php

I have two dropdownlist boxes. If I click on the first dropdown box, then the values have been changed in the second listbox accordingly to first listbox.
For example:
One is Fruits,vegetables,Birds. If i click on the Fruits then it shows the fruit list items in the second list box. It is same for other list also.

Number of dropdowns based on selection of first dropdown

Programming in Bootstrap and PHP I am trying to create a dynamic form which has the following.
User uses a dropdown to select number from 1 to 10.
The page then displays x number of dropdowns.
Each dropdown is the same and displays a list of userID from a MySQL table tblUsers
Once the user makes a selection from each dropdown, it then shows a second dropdown immediately underneath showing a list of videos from a second MySQL table tblVideos. Meaning that the second dropdown is based on the results from the first.
Once all dropdowns have been selected. Submit is pressed and the results are sent as an array to the table tblVideoStored
Any ideas how the PHP and MySQL would be in a simple form..
Based on what you plan to achieve, you may want to look into combining php with ajax (Javascipt). Below are some examples that should set you on the right path

I want to create a dynamic dropdown in loop

My requirement is to display CSV headers as the first element, then for each header, I want to map the element to elements appearing in drop-down. When first drop-down element is selected, it should dynamically populate second drop-down.
Example say my csv has the headers: first, second, third my first drop-down has values: 1, 2, 3 Then Based on 1: I should get second drop-down as a, b Then Based on 2: i should get second drop-down as i, j Then Based on 3: I should get second drop-down as p, q
i.e. First: (drop-down if 1 selected) (drop-down a, b) appears.
My problem is I am getting this done when I do not run this on loop. When I give a for loop for populating the csv header, automatically, the send drop-down does not appear.
Any help would be appreciated!

PHP selection in dropdown list

I need to create 4 dropdown list where the options are the names of the candidates (ex. 5 candidates) in a certain position (ex.Representatives). When i select a candidate from the list in the first dropdown, there will be 4 options in the second dropdown, and in the third dropdown there will be 3 options and so on. To sum it up, what is the php code for removing the list in the next dropdown upon selection without submitting it yet.
Use jQuery......jQuery help you to do validations easily. So it may take less time for client side validation
For e.g.;
$("#id_of_dropdown").change(function () {
// Some Code Here like you want to change another dropdown put if else here
});

How to get value from multiple drop down fields with the same name

I have added 5 drop down fields in my form with the same name. These field will be displayed based on selected country's radio button.I have 5 radio buttons named as "USA,INDIA,UK,EURO,AUS".
If i select USA, 1st drop down contains US sizes, will be displayed.
If i select INDIA,2nd drop down contains INDIAN sizes, will be displayed.
All are working Good. Now i have an issue with store that value to my DB in magento. When i submit the form, 5th drop down field(EURO sizes) value only saved.
If i select size other than EURO,I got an empty value. If i select Euro size, I got correct value.I hope you understand my problem. Please guide me to solve mine issue guys!
You can add disabled attribute to other drop-downs when you show the selected one. This way the browser will ignore the disabled ones.
Or, you could append [] to your drop-downs' name, like this:
<select name="name[]"> ... </select>
This way you will get an array in the request variable, then you can decide which to use in the array according to your radio button value.
