post checkbox value

There are many links that lets you know how to handle post values from checkboxes in php.Look at this link: http://www.html-form-guide.com/php-form/php-form-checkbox.html

Single check box

HTML code:

<form action="checkbox-form.php" method="post">    Do you need wheelchair access?    <input type="checkbox" name="formWheelchair" value="Yes" />    <input type="submit" name="formSubmit" value="Submit" /></form>

PHP Code:

<?phpif (isset($_POST['formWheelchair']) && $_POST['formWheelchair'] == 'Yes') {    echo "Need wheelchair access.";}else{    echo "Do not Need wheelchair access.";}    ?>

Check box group

<form action="checkbox-form.php" method="post">    Which buildings do you want access to?<br />    <input type="checkbox" name="formDoor[]" value="A" />Acorn Building<br />    <input type="checkbox" name="formDoor[]" value="B" />Brown Hall<br />    <input type="checkbox" name="formDoor[]" value="C" />Carnegie Complex<br />    <input type="checkbox" name="formDoor[]" value="D" />Drake Commons<br />    <input type="checkbox" name="formDoor[]" value="E" />Elliot House    <input type="submit" name="formSubmit" value="Submit" /> /form><?php  $aDoor = $_POST['formDoor'];  if(empty($aDoor))   {    echo("You didn't select any buildings.");  }   else  {    $N = count($aDoor);    echo("You selected $N door(s): ");    for($i=0; $i < $N; $i++)    {      echo($aDoor[$i] . " ");    }  }?>

in normal time, checkboxes return an on/off value.

you can verify it with this code:

<form action method="POST">      <input type="checkbox" name="hello"/></form><?phpif(isset($_POST['hello'])) echo('<p>'.$_POST['hello'].'</p>');?>

this will return

<p>off</p>

or

<p>on</p>

You should use

<input type="submit" value="submit" />

inside your form.

and add action into your form tag for example:

<form action="booking.php" method="post">

It's post your form into action which you choose.

From php you can get this value by

$_POST['booking-check'];
