Im trying to make a PHP cart

[cnotation]

Hello,

I am new to PHP, its only been a few days. So I figure what better to learn then to make my own script. Anyway I am stuck on something that seems should be simple....

On my product page there is a 'drop select' and a submit button.

This code is:

<form method='post' action='cart.php'>
<input type='hidden' name='code' value='0222'>
<select name='num' size='1'>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select>
<input type='submit'></form>

My question is.... How do you umm, get the value from 'drop select'... "num" ?

$_POST[code] works

but

$_POST[num] doesn't.

I dont know what has happened to you,but heres its work

PHP Code:


if(!$_POST['submit']) {
    echo "<form method='post' action=''>
    <input type='hidden' name='code' value='0222'>
    <select name='num' size='1'>
    <option value=1>1</option>
    <option value=2>2</option>
    <option value=2>3</option>
    </select>
    <input type='submit' name='submit'></form>";
}
else {
    echo $_POST['code'];
    echo "<BR>";
    echo $_POST['num'];

} 


May be you was wrong with $_POST[num],it should be $_POST['num']

Thanks, I tried $_POST['num'].. didnt work either.. is there another way to get the value??

sounds like you are losing that return value somewhere. try this on cart.php:

PHP Code:

print_r($_POST); 


That should print out the values of your request, num should be in there, if not, post the output from the print_r.

print_r($_POST);

gave me this..

Array ( [code] => 0222 [num] => )

Gosh this is annoying.. I cant even get past the second page. And the make matters worse... $_POST has failed me, what little confidence I had is shook.

I dont know why this works

foreach ($_POST as $field => $value)
{
echo "$field = $value<br>";
}
but the others dont

put quotes around your select box option values
