Disable a checkbox when another one is checked

[Eiolon]

Hi all.  I am wanting to disable a check box when another one is checked.

 

Here is a screenshot of what I am trying to do.

 

 

Basically, if the registration fee box is checked I want the online registration box to be disabled (because participants can't pay online from the website).

 

Thanks!

Either use a radion button, or post your question in the Javcascript forum.

So I take it this cannot be done with PHP?

 

I was reading on a solution using Javascript but it appears it only works in IE.

the check boxes have to have the same name, in that case when you select one the other one becomes unselected

PHP is server-side. Meaning it does not know anything that goes on after the data is displayed without a POST BACK to PHP.

 

Javascript and html is Client-side, which means that they can interpret stuff when a user clicks on something without a POST BACK.

This is not PHP but,

 

<form>
<input type="radio" name="option" value="0"> A registration fee is required for this program.
<br />
<input type="radio" name="option" value="1"> Ask for participants age when registering for this program.
<br />
<input type="submit" name="submit" value="Submit">
</form> 

 

Then you just add the additional options to the form as needed.
