复选框始终只显示“打开”

Question

this is how I have 2 checkbox and I do not want that you should only click on them simultaneously. it must only be possible to click on one at a time!. in the present to when I clicked the news, so it must enter a number in there to write "on". I would like to later be sure it is entered into the database.

the problem is that it appears to say "on" no matter what!?

<form action="#" method="post">
                    <table>
                        <tr>
                            <td>Emne</td>
                            <td>Vigtigt: <input type="checkbox" name="vigtigt" class="new"> Nyhede: <input type="checkbox" name="nyhede" class="new"></td>
                        </tr>
                        <tr>
                            <td>Title</td>
                            <td><input type="text" name="title" maxlength="50" class="new"></td>
                        </tr>
                        <tr>
                            <td>Tekst</td>
                            <td><textarea name="tekst" cols="20" rows="15" class="new"></textarea></td>
                        </tr>
                        <tr>
                            <td><input type="submit" name="opret" value="Opret Blog" class="new"></td>
                            <td></td>
                        </tr>
                    </table>
                    <?php
                    if(isset($_POST["opret"]))
                    {
                        if($_POST["vigtigt"] != "")
                        {
                            echo $_POST["vigtigt"];
                            echo "<br />";
                            echo $_POST["nyhede"];
                        }
                        elseif ($_POST["nyhede"] != "")
                        {
                            echo $_POST["vigtigt"];
                            echo "<br />";
                            echo $_POST["nyhede"];
                        }
                        else
                        {
                            echo "Fejl!";   
                        }
                    }
                    ?>
                </form>

Answer 1

You have to define a value attribute for it to:

 <input type="checkbox" name="vigtigt" class="new" value="MyValueHere">

This way you will receive its value when its checked.

Edit:

To have only one selected at a time you will have to use type="radio" and give them the same name and different values.

<input type="radio" name="vigtigt" class="new" value="MyValueHere">
<input type="radio" name="vigtigt" class="new" value="MyOtherValueHere">
