I am at the moment making a program where in a html file there are 5 checkboxes for the user to choose from. Each checkbox represents a letter so in mine it goes A, B, C, D, E. When the user clicks on the submit button it takes you to a php page that displays what numbers they checked.

Here is the html code ive done,


<html>

<div id="entryform">

    <form method="GET" action="phpprogram.php">

        <label for="option1"></label><input type="checkbox" name="option1" value="A"> A<br />

        <label for="option2"></label><input type="checkbox" name="option2" value="B"> B<br />

        <label for="option3"></label><input type="checkbox" name="option3" value="C"> C<br />

        <label for="option4"></label><input type="checkbox" name="option4" value="D"> D<br />

        <label for="option5"></label><input type="checkbox" name="option5" value="E"> E<br />

        <br />

        <input type="submit" name="submit" value="Show Letters" />    

    </form>

</div>


</html>

I'll assume you're trying to use POST instead of GET (POST is the preferred method). First of all checkboxes can be placed into its own array for simplicity, notice how I use "options[]" to handle each option:

<html>
<div id="entryform">
    <form method="POST" action="phpprogram.php">
        <label for="option1"></label><input type="checkbox" name="options[]" value="A"> A<br />
        <label for="option2"></label><input type="checkbox" name="options[]" value="B"> B<br />
        <label for="option3"></label><input type="checkbox" name="options[]" value="C"> C<br />
        <label for="option4"></label><input type="checkbox" name="options[]" value="D"> D<br />
        <label for="option5"></label><input type="checkbox" name="options[]" value="E"> E<br />
        <br />
        <input type="submit" name="submit" value="Show Letters" />    
    </form>
</div>

</html>

phpprogram.php:

<?php 
//If form was sent
if(isset($_POST['options'])) {
    //Iterate through options[] array
    foreach($_POST['options'] as $opts) {
        //handle each option
        print $opts . " selected.<br/>";    
    }
}
?>

This will list each option selected.

If a suggested code/method fails, informing us is less important than telling us why or what errors occurred.

Additionally, the label tag isn't really used the best way....

<input type="checkbox" name="options[]" value="A" id="option1"><label for="option1"> A</label><br />

i.e. the label shall be around the text connected to the checkbox, and the checkbox needs an id attribute so the label knows which input it's a label for
