[RESOLVED] POSTing checkbox selection

DrexlSpivey

Dear All,

can you please help me sort out something re POSTing data from a checkbox form.

Sending page is:

$my_array = array('dog', 'cat', 'horse', 'badger');

echo "<form method=\"post\" action=\"arrayreceive.php\" name=\"myForm\">";

foreach ($my_array as $animal) {
echo "<input type=\"checkbox\" name=\"selectedanimals[]\" value=\"".$animal."\">$animal<br>";
}
echo "<input type=\"submit\" value=\"submit\">";
echo "</form>";

Receiving page is:

if ($_POST['selectedanimals[]']) {
echo "something was received <br>";
} else {
echo "nothing was received <br>";
}

$selected_animals[] = $_POST['selectedanimals[]'];

foreach ($selected_animals as $animal) {
echo "From the POSTed array ----- $animal<br>";
}

The POSTed data is never received, and I cannot figure out why. (Using PHP5, with Register_globals off – I think it worked when they were on, I don't have control of register_globals).

Can anyone please suggest how I can get this to work.

Thanks in advance.

It makes it much easier to read if you enclose your code in the [ php][/code] BBCode tags . . .

The array and all the data is being passed to the second script. I've changed a few things for you so you can see for yourself that it makes it, and the values it holds. Whenever I'm in doubt as to what values are being passed, I start echoing them to the screen, so I know for sure what is going on.

<?php
print_r($_POST);
// added the print_r() to show the POST array, note that it has an array within the POST array . . .

//check if empty $_POST['selectedanimals'] not ['selectedanimals[]']
if (!empty($_POST['selectedanimals'])) { 
          echo "something was received <br><br>";
} else {
          echo "nothing was received <br>";
}

//take the array in the POST array at index 'selectedanimals' and put it in the $selected_animals array.
$selected_animals = $_POST['selectedanimals'];

// changed to echo key and value so you can see how it's now stored in the new array.
foreach ($selected_animals as $key => $val) { 
          echo "From the selected_animals array: key:" . $key . " Value : " . $val . "<br>";
}
?>
