Accessing a Single Checkbox

[cpd259]

I have the following HTML field description:

<input type="checkbox" id="truck"> Check Truck <br>

It is a single checkbox and I would like to know if the user checked it or not. I have tried using the following PHP code but it doesn't seem to work as I always get the box being not checked when it is ie Truck is not checked.

if (isset($_POST["truck"])) {
echo "Truck is checked";
}
else
{
echo "Truck is not checked";
}

Should I put a pair of [] after the id even though it is a single check box?

Thanks for you help in advance...Charlie

Your input needs a name, <input type="checkbox" id="truck" name="truck">

Thanks...Someone told me that under newer versions of HTML, the 'name' would be going away and the 'id' would be replacing it. This is why I didn't put the 'name' in there.

I don't know where name is being removed from, the xhtml standards don't allow it in some elements, but all input elements allow it. And you need names because PHP uses them to identify diffrent $_POST variables.
