Getting the value of an input box?

[denhamd2]

Hi, hope someone can help me with this:

I have a cart page and i want to be able to update quantities of products using input boxes. So far so good. These input boxes get their values form variables from the previous page. Here is the code:

<input name="'.$key.'" value="'.$pspackdetails.'" type="text" size="3">

As you can see, the name and value are both dynamically generated. What I need is to get the value of the box as a variable so I can multiply it by a price.... something like input.name.value but does anybody know how to get this value using PHP?

Please help!

If you're using the POST method everything sent to the action URL will be in the $POST super global. If the method is GET (it's usually POST for forms) the values will be in $GET.

$_POST[$key] would have the value that $pspackdetails had.

You would just have to use the same method you used to define $key in the form as you do in the form processing.

I've tried a few things but I don't know how to go about doing this. Please can you have a look at my code and tell me how I could get that?

foreach($SESSION as $key => $val)
{
$productdetails = $val;
$pspackdetails = ereg_replace("", "</span><span class='colour'>", $val);
$pspackdetails = ereg_replace("-x-", "</span><span class='rates'>", $pspackdetails);
$pspackdetails = ereg_replace("--y--", "</span><span class='dimensions'>", $pspackdetails);
if($val != "Submit") { if($val != "Add To Cart") { if($val != "keane") { if($val != "ian") {
if($val != '')
{
if(preg_match('|_q$|',$key))

{ echo '<span class="quantity"><input name="'.$key.'" value="'.$pspackdetails.'" type="text" size="3"></span><br>'; $amount = $pspackdetails; }

if(preg_match('||',$key)) {

$parts = explode('-x-',$productdetails);

for($i = 0; $i < count($parts); $i++) // we start at zero
{
$prices[] = strtr($parts[$i],'_',' '); // and clean the underscore
}

echo '<span class="item">'.$pspackdetails.'</span>'; }

// MULTIPLICATION BIT
print "<b>".($parts[1] * 1)."</b> Amount: $amount";
}
}
} } } }
echo '</p><p align="center"><input type="submit" name="Submit" value="Submit"></p></form><p align="center"><a href="javascript:history.go(-2)">Back to Shopping</a></p>';
}

Sorry forgot to mention I'm using session variables...
