Dynamically associating array with textfield

[kilbey1]

I have a form consisting of 3 dropdowns next to text fields, ie:

Label: Textfield Select

Time1: 2 Days
Time2: 2 Hours
Time3: 2 Months

(the option 'Week' is also available')

I can go so far as to determine that Time1 has Day selected, Time2 has Hours selected, and Time3 has Months selected, like so:
Array ( [0] => hour [1] => day [2] => month )

I then want to compare apples to apples by converting days, months, and weeks into hours (and eventually back again), so now I want to dynamically determine that Time1 (array 0) is associated with Time1, so textfield must now be 224 to equal 48 hours, while Time3 (array 2) must be 2730.484398.

Here is what I have so far; how can this be better written?

	
$time = array("hour" => "hour", "day" => "day", "month" => "month", "week" => "week");
	$timeO = $time;
	$timeP = $time;
	$timeM = $time;


function buildSelect($selArr, $selOpt){ 
    $selectText = $selOpt[0]; 
    if ($selectText != "") { 
        $selDefault = "selected"; 
        if ($selOpt[1] == "true") { 
            $selDefault = ""; 
        } 
        echo "<option $selDefault>$selectText</option>\n"; 
    } 
    foreach($selArr as $key => $value){ 
    $sel = ""; 
        for ($loop = 2; $loop < count($selOpt); $loop++) { 
            if ($selOpt[$loop] == $key) { 
                $sel = "selected"; 
            } 
        } 
        echo "<option $sel value='$key'>$value</option>\n"; 
    } 
    return; 
} 

?>

foreach ($times as $value) {
	$day = array_search('day', $times);
	$hour = array_search('hour', $times);
	$week = array_search('week', $times);

}

it might be a bit simpler if you could integrate this into your code

<?php

define('HOUR', 3600);

$t1 = ( strtotime('2 months') - time() );
$t2 = ( strtotime('2 days')   - time() );
$t3 = ( strtotime('2 hours')   - time() );

$tt1 = $t1 / HOUR;
$tt2 = $t2 / HOUR;
$tt3 = $t3 / HOUR;

echo "2 months = $tt1 hours | 2 days = $tt2 hours | 2 hours = $tt3 hours";

?>

you will see that should come out with the hours just right.

Hey, thanks for that tip! Know how I can convert decimals (ie. 3.5 for 3 1/2 hours) correctly? Any such entry gives me a changing negative result.

Here's how I've implemented your code thus far:

define('HOUR', 3600); 

<...snip...>

$To = $_POST['To'];
$Tp = $_POST['Tp'];
$Tm = $_POST['Tm'];
$timeO = $_POST['timeO'];
$timeP = $_POST['timeP'];
$timeM = $_POST['timeM'];

$numbers = array($To, $Tp, $Tm);
$times = array($timeO, $timeP, $timeM);

$t1 = $numbers[0] . ' ' . $times[0];
if ($numbers[0] > 1) { $t1 .= "s"; };
$t2 = $numbers[1] . ' ' . $times[1];
if ($numbers[1] > 1) { $t2 .= "s"; };
$t3 = $numbers[2] . ' ' . $times[2];
if ($numbers[2] > 1) { $t3 .= "s"; };


echo $t1 . "<BR>" . $t2 . "<BR>" . $t3 . "<BR>";
$t1 = ( strtotime(' '. $t1 .' ') - time() ); 
$t2 = ( strtotime(' '. $t2 .' ') - time() ); 
$t3 = ( strtotime(' '. $t3 .' ') - time() ); 
echo $t1 . "<BR>" . $t2 . "<BR>" . $t3;
