[Resolved] checkbox question

[cidesign]

Hello;

Been scratchin my head on this one. I have to do simple checkbox validation without JS and I thought the following code inside of my form would give me the checkbox value. However when I click submit no value is displayed for the $box variable.

$box=$_POST['BoxValue'];
echo $box; //no value gets displayed after submit pressed.

<form>
<input type=\"checkbox\" name=\"BoxValue\" value=1>
</form> // form is submitted to $ _SERVER['PhP_SELF'].

This is the only checkbox in the form. The other elements of the form display with no issues so am I missing something with checkboxes ?

I am only concerned that the user clicked the checkbox. Again this is the only form element that doesn't post to the page.

Quote from somewhere:

"It's important to realize that a checkbox is only submitted if it's actually checked. Otherwise, its very absence tells you what you need to know - the user didn't click this checkbox. In the case of checkboxes, you can check explicitly to see whether the value was set (as follows...) "

<form name="form1" method="post" action="">
<input type="checkbox" name="BoxValue" value="1">
<input type="submit" name="Submit" value="Submit">
</form>

$result =($_POST['BoxValue'])?"BoxValue: 1":"BoxValue: Not checked";
echo $result;
