$_REQUEST gives empty value while form submits array value

Question

this is my url

db_control.php?workname=Test+message&worktype=1&workscore=10&multi%5B%5D=4&multi%5B%5D=24&frmsubmit=

this is my php code

if(isset($_REQUEST['frmsubmit']))
{
    echo $_REQUEST['workname']; echo '<br>';
    echo $_REQUEST['workscore'];echo '<br>';
    foreach($_REQUEST['multi'] as $mlti => $n)
    {
        echo $n;echo '<br>';

I know, I know, it is hard to find a solution when you can't replicate the error. — Amarnasan, Dec 16 '15 at 08:24
What happens if you hit this address (replacing %5B%5D with brackets)?: db_control.php?workname=Test+message&worktype=1&workscore=10&multi[]=4&multi[]=24&frmsubmit= — Amarnasan, Dec 16 '15 at 08:35
What is your PHP version? The conversion from [ ] to array might not be for all versions. Mine is 5.5.6 — Amarnasan, Dec 16 '15 at 08:59
No worries.. i found.. there is an include file to get user information that blocks. I just remove the include its woked. but cant find why its blocked. working on it.. thanks for all... — John Babu, Dec 16 '15 at 09:29

The right way to do this would be to pass all values of multi in one parameter multi in the following way.

Use:

http://example.com/workname=Test+message&worktype=1&workscore=10&multi=4,24&frmsubmit=

Instead of:

http://example.com/workname=Testmessage&worktype=1&workscore=10&multi[]=4&multi[]=24&frmsubmit=

And access the values of "multi" by using explode like this:

if(isset($_REQUEST['frmsubmit']))
{
    echo $_REQUEST['workname']; echo '<br>';
    echo $_REQUEST['workscore'];echo '<br>';
    $multiParam = explode(",",$_REQUEST['multi']);
    foreach($multiParam as $mlti => $n)
    {
        echo $n;echo '<br>';
    }
}

thanks that variable multi[] is from dropdown multiple selection option. how can i do this..? – John Babu Dec 16 '15 at 08:12
That's not right. The way he dealt with multi parameters is perfect and way more elegant than yours. Also, what if one of the multi values include a comma? Bang! You got a splitted value. – Amarnasan Dec 16 '15 at 08:13
I provided an alternate solution to the problem he is facing. Why don't you enlighten us as to why it isn't working? @Amarnasan – bIgBoY Dec 16 '15 at 08:18
I enlighted you by saying I tried it and it worked. As you can see in my comment to his answer. – Amarnasan Dec 16 '15 at 08:18
