PHP – get the check box values of HTML form
Editor’s note: In some cases when you try to create a HTML form for user to input data, you might like to include a set of check boxes for them to input multiple choices, however in order to get the data from a set of check boxes with PHP, I think the easier way is to use array for it, and here in this example I am going to show you how to do so
First we create a HTML form with a set of check boxes, once submitted, the data will pass to test.php:
<form action="test.php" method="post" name="form1" /> <input type="checkbox" name="color[]" value="red" /> red <input type="checkbox" name="color[]" value="green" /> green <input type="checkbox" name="color[]" value="yellow" /> yellow <input type="submit" name="submit" value="submit" /> </form>
See the check boxes are in one array color[ ] , now we take a look at the test.php file
First we have to get only the value from boxes which are checked, if condition is used here:
if (isset($_POST['color'])){ ............. }
for all the selected check boxes, we then use a foreach() to loop everyone of them and print it out onto the screen:
if (isset($_POST['color'])){ foreach ($_POST['color'] as $value) { echo $value; echo "<br>"; } }
