radio button selection

pauldh

😕Presntly I can launch a prices with a start button (e.g.. run movie)

Problem:
How can I launch other movies depending of the setting by radio-buttons?
In this example:
if radio-button = 1 => run movie-1
if radio-button = 2 => run moviie-2

The radio-button selection must be modified by selecting the wanted number but WITHOUT another submit button therefor

Thus: how to use the radio-button value as variable for selecting another movie and modify immediately the radio-button value without a submit button/
thx

First, you need to understand how PHP works. PHP is all on the server, so all your PHP code requires some kind of request from the client (the browser).

This request can be either a regular form submit, a user clicking a link, or an AJAX request (which I presume is what you want here?)

What code do you have so far?

I have tried the following:

<html>
<head>
<script>

function getRadioValue(id) {
var $radioBtn = document.getElementById(id);
alert($radioBtn.value);
}
</script>

</head>
<body>
<form action="" method="post">

<input type="radio" id="btn1" name="123" value="value1" onClick="Javascript:getRadioValue(this.id)"/> 1 <br>

<input type="radio" id="btn2" name="123" value="value2" onClick="Javascript:getRadioValue(this.id)"/> 2 <br>
<input type="radio" id="btn3" name="123" value="value3" onClick="Javascript:getRadioValue(this.id)"/> 3 <br>
</form>
</body>

</html>

the only thing I need is to get a variable which i can use in php

You can give any other solution of course , ajax, ...

Ah, well I see some of your problems.

You don't really need the javascript: part in your onclick event handlers, as Javascript is assumed anyway, and it may break in older browsers.

You're not using any PHP, so not sure why you're prefacing all your variable names with $, take those out.

Now where are your videos, and the code that you're using to display them?

<?PHP
activated by submit button
if (isset($POST['submit-gedrukt'])) {
$selected_button = $POST['hulp']; // content = "value' waarde in de button forn
}

$a = 'checked';
$b = '';
$c = '';

selektie =

<?
echo $selected_button;
?>

<?php
if ($selected_button == "1") {
echo "altijd";
$a = 'checked';
$b = 'unchecked';
$c = 'unchecked';
}
else if ($selected_button == "2") {
echo "soms";
$a = 'unchecked';
$b = 'checked';
$c = 'unchecked';
} else if ($selected_button == "3" ){
echo "nooit";

$a = 'unchecked';
$b = 'unchecked';
$c = 'checked';
}
?>

<FORM name ="formnaam" method ="post" >
<INPUT TYPE = 'Radio' Name ='hulp' value= '1' <?PHP print $a; ?> >altijd <br> 
<INPUT TYPE = 'Radio' Name ='hulp' value= '2' <?PHP print $b; ?> >soms <br>
<INPUT TYPE = 'Radio' Name ='hulp' value= '3' <?PHP print $c; ?> >nooit <br>
<P>

</FORM>

<FORM>
<INPUT type="button" value="button film1" onClick="myframe.location.href='http://aaa.bbb.cc'">
</FORM>

</body>
</html>

Here the film is launched (derived from vimeo.com ) , but there eis not yet a coupling between radio button selection and launching the movie(S).

Can you give based on this a solution please?
