Conditional IF statement to HTML form checkbox to add form elements

[ashbullmanuk]

Hi everyone,

 

I am trying to add a conditional if statement to a checkbox in an html form, so that when the user checks the box, the a new set of form elements appear below it.

 

I created the new form elements in a seperate file, and planned on using the include command, so something like:

 

If ('kick start' == "yes"

{ include ('kickstart.html');}

 

the html check box code is

Kick Start

 

nothing happens though when i click the checkbox.

 

Any thoughts?

Javascript is what you need, but I'm not a js guru.

Could you use chained select boxes with javascript? See this:-

i checked out the link, but what i need is that when a user checks a box a whole new section of form appears, with text fields and areas etc.

 

I dont know much about JS either, so if anyone knows where i might help or a tutorial on this or with PHP would be very much appreciated.

 

I found a source with what looked like it could do what i want, but the page threw a 500 internal server error when loading the it. the new code if anyone maybe able to shed some light is:

 

<?php

//Defining checkbox variable

$kick_start = 'unchecked';

 

if(isset($_POST['continue'])) // the continue button to execute the following

{

if ?(isset($_POST['kick_start']))

{

$kick_start = $_POST['kick_start'];

if ($kick_start == 'yes')

{ include("kick_start_form.html");

}

}

}

?>

 

Many thanks everyone

You can make a show/hide or expand/collapse section with javascript or PHP. Here is a PHP example, the benefit being that it works even if javascript is disabled:-

 

Item 1 just happens to be a hidden form, but it could be anything:-

maybe try removing the typos first:

 

if ?(isset($_POST['kick_start']))

 

the question mark above looks like a typo to me
