Question

I need to add a zero to the date value that is posted as the MySQL date value will be used as a directory path to show added photos. Currently the directory is saved as 2012-2-5 and the MySQL entry is 2012-02-05.

I have tried the following, however it doesn’t seem to be working:

$dates = array($_POST['photos_year'], $_POST['photos_month'], $_POST['photos_day']);
    foreach($dates as $date) {
    if (strlen($date) == 1) {
        $date = '0' . $date;
    }
    }
$photos->date = $dates[0] . "-" . $dates[1] . "-" . $dates[2];

I am using a for loop to create the date form, it might be easier for me to edit this however I haven’t had any success:

<select name="photos_month"  id="photos_month" tabindex="3">
    <option value ="">- Month -</option>
    <?php 
    for($date=01;$date<=12;$date++) {
        if (isset($photos) && $date==$month) {
            echo "<option value='".$date."' selected='selected'>".$date."</option>";
        } else {
            echo "<option value='".$date."'>".$date."</option>";
        }
    }
    ?>
</select>

You need to update the foreach to be

foreach ($dates as &$date)

Currently, $date is a new symbol and will not overwrite the value. That should fix it, but it may be nice to have the correct strings in the options too. You can use str_pad to do that.
