get check box value

[phppaper]

Dear all,

 

How can I use php to get the check boxs values (only the checked one):

 

<input type="checkbox" name="option[]" value="Milk"> Milk<br>

<input type="checkbox" name="option[]" value="Butter"> Butter<br>

<input type="checkbox" name="option[]" value="Cheese"> Cheese

 

Thanks!!

if you are posting it using a PHP form something in this manner

($_POST['checkboxname] == "ON")

 

or a group of checkboxes

 

page_html.php

 

      <form method="post" action="">

      <input type="checkbox" id="colour[]" value="red"> Cat<br>

      <input type="checkbox" id="colour[]" value="blue"> Mouse<br>

      <input type="checkbox" id="colour[]" value="green"> Car<br>

      <input type="checkbox" id="colour[]" value="yellow"> DaniWeb

      </form>

 

php.php

 

      <?php

      $things = serialize($_POST['colour']);

 

      $query = "INSERT INTO table(colour) values($colour)";

      mysql_query($query) or die(mysql_error());

      ?>

 

Just turn it into an array and dump the contents to db. You have to "serialize" the data first and don't forget to "unserialize" when you are taking the data back out.

Hi,

 

if (isset($_POST['option']) && is_array($_POST['option']))
{
foreach ($_POST['option'] as $option)
{
	echo $option.', ';
}
}
