array elements in a select menu problem

markwin

hi all

ive got a select menu that displays the week beginning dates for the next 3 weeks. eg mon 18th nov, mon 25th nov, etc.

ive got it so that it uses an array of 4 values for the date, and makes the 4 variables of the array the value of the selected item.

echo "<OPTION value=\"$dates[dayofweek] $dates[th]$dates[dayofmonth] $dates[month]\">$dates[dayofweek] $dates[th]$dates[dayofmonth] $dates[month]</OPTION>";

thats what each of the select items looks like. what it does is first get the system date before this, and then works out the next 4 week beginning dates. its probably not the best way to do it but it works for me fine. now i can refer to the selected item fine, and can echo the date selected no problems like so
echo "<BR>". $dates[month];

but how do i echo one of the array elements of the selected item??

ive tried these
echo "<BR>". $Datess[$dates[dayofmonth]];
echo "<BR>". $Datess[dayofmonth];
echo "<BR>". $Datess[dates[dayofmonth]];

just cant seem to get it to refer to one of the array elements of the selected item. can anyone help me with this?

What do you mean "echo the array elements of the selected item"? The "selected item" as I understand it is the value of the selected option (is that named Datess?), and that's a string, not an array. In that case, you'll need to take the string and parse it either into an array (explode() on the spaces), or use strtotime() to convert it into a timestamp from which you can extract time/date information.

ive used an array to make the 4 elements of the array the value and display value of the select items.

if ($day == "Monday") {
$dates = array("dayofweek", "dayofmonth", "th", "month");
$dates["dayofweek"] = $day;
$dates["th"] = $today;
$dates["dayofmonth"] = $th;
$dates["month"] = $month;
echo "<OPTION value=\"$dates[dayofweek] $dates[th]$dates[dayofmonth] $dates[month]\">$dates[dayofweek] $dates[th]$dates[dayofmonth] $dates[month]</OPTION>";
}

what this does is put the 4 values i have worked out in my formula, and puts them into the 4 array elements. it then makes the value of the select item the 4 values of the array.

i jsut want to refer to one of the elements of the array of the selected item, the day of the month for example. so when one item is selected, i want to be able to just get the 3rd element of the array, which is dayofmonth. how would i just refer to that part.

Well I'm obviously still misunderstanding your question, because it still sounds like the same question as the one I answered.

This line is wrong though:

 $dates = array("dayofweek", "dayofmonth", "th", "month");

What you get from that is

$dates[0]='dayofweek';
$dates[1]='dayofmonth';
$dates[2]='th';
$dates[3]='month';

It can be dropped because it's just sticking things in the $dates array that never get used.

In fact with the code you give the array is completely redundant. It's equivalent to just going


if ($day == "Monday") {
echo "<OPTION value=\"$dayofweek $th$dayofmonth $month\">$dayofweek $th$dayofmonth $month</OPTION>";
}
