Passing array values to another page

[cheeks2k]

I have various checkbox values which I want to pass to an XML page, but I can't work out how to do it. I feel like I'm close and I've been searching all through the forums but can't find the answer I need. Here's the relevant code:

<form action="<?php MyFunction(); ?>" method="post">
4. Road proposals by private bodies: <input type="checkbox" name="box[0]" /><br />
5. Public paths or byways: <input type="checkbox" name="box[1]" /><br />
6. Advertisements: <input type="checkbox" name="box[2]" /><br />
7. Completion Notices: <input type="checkbox" name="box[3]" /><br />
8. Parks and countryside: <input type="checkbox" name="box[4]" /><br />
9. Pipelines: <input type="checkbox" name="box[5]" /><br />
10. Houses in multiple occupation: <input type="checkbox" name="box[6]" /><br />
11. Noise Abatement: <input type="checkbox" name="box[7]" /><br />
12. Urban development Areas: <input type="checkbox" name="box[8]" /><br />
13. Enterprise Zones: <input type="checkbox" name="box[9]" /><br />
14. Inner urban improvement areas: <input type="checkbox" name="box[10]" /><br />
15. Simplified planning zones: <input type="checkbox" name="box[11]" /><br />
16. Land maintenance notices: <input type="checkbox" name="box[12]" /><br />
17. Mineral consultation areas: <input type="checkbox" name="box[13]" /><br />
18. Hazardous substance consents: <input type="checkbox" name="box[14]" /><br />
19. Environmental and pollution notices: <input type="checkbox" name="box[15]" /><br />
20. Food safety notices: <input type="checkbox" name="box[16]" /><br />
21. Hedgerow notices: <input type="checkbox" name="box[17]" /><br /><br />
<input type="submit" value="Submit">
</form>
<?php
function MyFunction() {
global $box, $searches, $environment;
$box = array("<option4 />","<option5 />","<option6 />","<option7 />","<option8 />","<option9 />","<option10 />","<option11 />","<option12 />","<option13 />","<option14 />","<option15 />","<option16 />","<option17 />","<option18 />","<option19 />","<option20 />","<option21 />");
foreach ( $box as $box2 )
{
if ($_POST['box2']) { $boxtest = "$box2" ; }
}

$datenow = date( "d-m-y" );
$timenow = date( "H:i" );
$f = fopen ("secondtest.inc", "aw");
fwrite ($f, "$boxtest\n");
fclose ($f);
}
?>

I could do each checkbox with a separate value, but I heard arrays were easier!

here's a quick example of how you could clean your code up a bit:

$checkbox_array = array (
4 => 'Road proposals by private bodies',
5 => 'Public paths or byways',
6 => 'Advertisements',
7 => 'Completion Notices',
8 => 'Parks and countryside',
9 => 'Pipelines',
10 => 'Houses in multiple occupation',
11 => 'Noise Abatement',
12 => 'Urban development Areas',
13 => 'Enterprise Zones',
14 => 'Inner urban improvement areas',
15 => 'Simplified planning zones',
16 => 'Land maintenance notices',
17 => 'Mineral consultation areas',
18 => 'Hazardous substance consents',
19 => 'Environmental and pollution notices',
20 => 'Food safety notices',
21 => 'Hedgerow notices'
);

echo '<form action="' . $_SERVER['PHP_SELF'] . '" method="POST">';
foreach ($checkbox_array as $key => $value)
{
	echo $key . '. ' . $value . '<input type="checkbox" name="box[' . $key . ']"><br>';
}
echo '<input type="submit" name="submit" value="submit"></form>';

print_r ($_POST);

you would then have the array $_POST['box'] populated with the checked boxes to do whatever you want with

[CaptianChaos]

<input type="checkbox" name="box[0]" />

that will never be true in your next page. Change to:

<input type="checkbox" name="box[0]" value="1" />

[devinemke]

<input type="checkbox" name="box[0]" />

that will never be true in your next page. Change to:

<input type="checkbox" name="box[0]" value="1" />

actually that's not really necessary. checked checkboxes return a value, unchecked ones do not. so you can simply use isset() to test your boolean. as per the example code:

if (isset ($_POST['box']['12']))
{
echo 'you checked Urban development Areas';
}

OK, I'll have to come back to this. I'm obviously not at the level I thought I was because I just can't get it to work.
