Question

I am new to PHP and i need to know how to display entered data on a page. I will clarify. There is a text box on a page and when the user types something in it and clicks submit, a blank page will come up that says: You entered [ENTERED DATA HERE]. i want to do this so that i put a code in the text box, and it will automatically generate the correct iframe.

<iframe marginwidth="0" marginheight="0" src="http://jb-radio.com/movies/play.php?mu=[ENTERED DATA HERE]" frameborder="0" height="360" scrolling="no" width="640"></iframe>

Please help on this script (i think it is done with PHP) i think this should be fairly simple.

Answer 1

You can do this in client-side Javascript with no PHP involved:

 <iframe id="the_iframe" style="display:none;" marginwidth="0" marginheight="0" src="" frameborder="0" height="360" scrolling="no" width="640"></iframe>

 <input id="the_input" type="text" />
 <input id="the_button" type="button" value="Click me to change the iframe" />

 <script type="text/javascript">
   document.getElementById('the_button').onclick = function() {
     var theUrl = 'http://jb-radio.com/movies/play.php?mu=';
     theUrl = theUrl + document.getElementById('the_input').value;
     var theIframe = document.getElementById('the_iframe');
     theIframe.style.display = 'block';
     theIframe.src = theUrl;
   };
 </script>
