Check Box

[Radon3k]

I have a check box on a page I made and in order for you to go to the next page, that must be checked, and if not, it'll return with saying it has to be checked. What would the code for this be? I'm not familiar with how to work with check boxes and radio buttons in PHP. Thanks. 🙂

Consider

<input type="checkbox" name="hello" value="world">

If this checkbox is checked and submitted under the POST method, $POST['hello'] would be set and contain the string 'world'
Else $POST['hello'] would not be set.

The same applies to radio buttons, and indeed to most form controls.

Ahh, great, thanks! I wasn't sure if there was anything special you needed to do. That's simple enough, thanks again! 🙂

What about for drop down lists? How would that work?

Consider:

<select name="colour">
<option value="">Colour</option>
<option value="red">Red</option>
<option value="green">Green</option>
<option value="blue">Blue</option>
</select>

Then $_POST['colour'] will be set (i.e. can use isset() to test) if one of the non-null options are selected.
