detect unchecked checkbox php

php

Solution

If a checkbox is not checked it will not be posted. `if(!isset($_POST['checkboxname']))` will do the trick.

Be aware, though, you should at least submit something so that you know the form was submitted in the first place.

if (isset($_POST['formWasSubmitted'])) {
    //form was submitted...let's DO this.

    if (!isset($_POST['checkboxname'])) {
        // checkbox was not checked...do something
    } else {
        // checkbox was checked. Rock on!
    }
}

Problem

Is there a way to check of a checkbox is unchecked with php? I know you can do a hidden field type in html but what about with just php when the form is submitted? I tried below no luck. ``` if(!isset($_POST['server'])||$_POST['server']!="yes"){ $_POST['server'] == "No"; } ```
