PHP日期和时间选择框

Question

I am populating three select boxes to give me 3 select boxes, containing day, month, time. I am using this current code to populate each option:

<select name="<?php echo $select2; ?>">
<?php 
$months = array(Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, Dec);
foreach ($months as &$value)
{
echo '<option value="'.$value.'">'.$value.'</option>';
}
?>
</select>

I am then converting the selected results into a single variable. which is stored in a DB as a DD-MM-YY format. How can I pull this info out of the database, and make the select boxes default to what ever has been pulled out from the DB?

Thanks guys

Answer 1

You can explode the DD-MM-YY string using the explode method. For example:

$pieces = explode("-", $date);

This should give you an array with 3 elements as follows:

Array(
  0 => "DD", // Days
  1 => "MM", // Months
  2 => "YY"  // Years
)

Now maybe go ahead and loop through the dates as you had been. If they match, put a checked attribute for that option.

foreach ($months as $value)
{
  if($value == $pieces[1]) // $pieces[1] is the months element as you'll notice above
    echo '<option value="'.$value.'" checked>'.$value.'</option>';
  else
    echo '<option value="'.$value.'" checked>'.$value.'</option>';
}

Your question was kind of vague, but something like this could work.
