Hello Group,

I'm working on my first PHP code and will appreciate if someobody could give me some help.

I have:

$strDays = array (       '','1st', '2nd', '3rd' ,'4th', '5th' , '6th', '7th', '8th', '9th', '10th',
                                      '11th', '12th', '13th' ,'14th', '15th' , '16th', '17th', '18th', '19th', '20th',
                                      '21st', '22nd', '23rd' ,'24th', '25th' , '26th', '27th', '28th', '29th', '30th',
                                      '31st'
                                    );
<? foreach ($strDays as $valDay){ ?>
<option selected><? echo $valDay; ?> </option>
<? } ?>

to populate a drop-down menu by days of month. Then I use it for the 2nd time for a 2nd drop-down menu and it points to 31th day. How  can I reset it back to 1th or first element of the array?

Thanks,
A

Hello,

Thanks but this is not what I had asked for. How can I reset the variable?

That actually is what you asked for; the only reason the dropdown comes up with 31 selected is because of the "selected" attribute in each of those <option> tags.

The way tolgaong wrote it, the 1st day will be selected.

No part of your code requires any "reset"; foreach doesn't work the same as next() and current() and all those where it's up to you to maintain the internal array pointer.

Is it possible the other <select> is overriden by something client-side (perhaps Javascript, or perhaps even your browser filling in a known form value like "date of birth" or you or something)?

Apart from that, if it's identical code it should be behaving identically.

Oh I see. Now I get it. I hadn't used "selected" in my previous code. Once again thanks both of you.
