Need To Include Radio Buttons And Checkboxes

deziner76hd · October 19, 2010

I have no idea where to go from here

Actually, there are two different instances of the array you'll need to deal with when using checkboxes. One is when you set up the form. The next is in processing the data from the form. Here's an example you can cut and paste into a new file to help you understand how it works. I was something like this that helped me understand how arrays interact with forms, and how they can be used to keep things grouped and organized. This isn't the only way to do it, but I feel it's one of the better ways, especially if you have a large number of checkboxes, or groups of checkboxes.

<?php
if( $_POST['submitted'] == 'yes') {
echo '<pre>';
print_r($_POST);
echo '</pre><br>';
if( is_array($_POST['boxes']) ) {
	foreach( $_POST['boxes'] as $key => $value ) {
		echo "Index: $key - Value: $value<br>";
	}
}
}
?>
<html>
<form action="" method="POST">
First: <input type="checkbox" name="boxes[]" value="first" <?php echo (is_array($_POST['boxes']) && in_array('first', $_POST['boxes'])) ? 'checked = "checked"' : ''; ?>><br>
Second: <input type="checkbox" name="boxes[]" value="second" <?php echo (is_array($_POST['boxes']) && in_array('second', $_POST['boxes'])) ? 'checked = "checked"' : ''; ?>><br>
Third: <input type="checkbox" name="boxes[]" value="third" <?php echo (is_array($_POST['boxes']) && in_array('third', $_POST['boxes'])) ? 'checked = "checked"' : ''; ?>><br>
<input type="hidden" name="submitted" value="yes">
<input type="submit" name="submit" value="Submit">
</form>
</html>
?>

Thank you

can you tell me why it prints this above the answers it prints?

Array
(
    [boxes] => Array
        (
            [0] => first
            [1] => second
        )

    [submitted] => yes
    [submit] => Submit
)

This is what it prints in entirety.

Array
(
    [boxes] => Array
        (
            [0] => first
            [1] => second
            [2] => third
        )

    [submitted] => yes
    [submit] => Submit
)


Index: 0 - Value: first
Index: 1 - Value: second
Index: 2 - Value: third
First:
Second:
Third:

I would think it should just print this with all three checked

Index: 0 - Value: first

Index: 1 - Value: second

Index: 2 - Value: third

A user gary submitted the contact form:

Did you notice it's 1:00am again? it seems like I am always up at 1:00 am working on something.

I want you to know I really do appreciate all the time you have put in helping me.

Pikachu2000 · October 19, 2010

The first part is the output from the print_r($_POST). I threw that in there so you'd be able to see exactly how the $_POST array is structured. That code block can be commented out or removed at any time. That output shows that $_POST is an array, containing 3 elements: 'boxes', 'submitted', and 'submit'. You can see the 'boxes' element is also an array, itself containing the 3 elements from the checkboxes.

The next block of code uses a foreach() loop to to through just the array in 'boxes', and output the values to the screen.

Is this starting to make more sense now?

deziner76hd · October 19, 2010

Yes The last explanation of how it is all put together actually clicked and gave me insight into how it all works. Now I will try to implement it into my existing form and get it to work.

Thank you

deziner76hd · October 19, 2010

Ok I see how this all works but I still can't get it to print to e-mail

deziner76hd · October 19, 2010

Well I am trying to learn and understand all this. I start to think I have things under control and when I try what I think will work (several variations) and it doesn't it's gets a little frustrating.

This is what is returned

A user Gary T White submitted the contact form: (working)

Full Name: Gary T White (working)

Email: [email protected] (working)

Gender: female (working)

Languages I Speak: English (not working)

Preferred Language: English (working)

Favorite color: Array (not working)

Education: HighSchool (working)

Check Boxes: Array (not working)

What am I not getting here?

deziner76hd · October 20, 2010

Ok I commented out:

if( $_POST['submitted'] == 'yes') {

echo '<pre>';

print_r($_POST);

echo '</pre><br>';

And All I can get it to print to email is:

Array

Why?

deziner76hd · October 20, 2010

And with the above commented out i still get this printed on the page

Index: 0 - Value: first

Index: 1 - Value: second

Index: 2 - Value: third

Warning: Cannot modify header information - headers already sent by (output started at /home/richardi/public_html/test2.php:33) in /home/richardi/public_html/test2.php on line 93

You can't print an array with echo. You need to print it by referencing the index key of the element that the value you want to print is stored in. That is done like this: echo $array['element']; and can be done in a loop to echo them all recursively.

foreach( $array as $key => $value ) {
     echo "The index with key: <b>$key<b> holds the value: <b>$value</b><br>";
}

And with the above commented out i still get this printed on the page

Index: 0 - Value: first

Index: 1 - Value: second

Index: 2 - Value: third

Warning: Cannot modify header information - headers already sent by (output started at /home/richardi/public_html/test2.php:33) in /home/richardi/public_html/test2.php on line 93

You'll notice a foreach loop like the above in the example code I gave you that's outputting those values. As far as the header error goes, you can't use header() after there has been any output at all to the browser, or you'll get that error, and the header() call will fail.
