 |
|
When I was converting our CMS code and templates to support multilingual sites, I noticed that {html_select_date} was not locale aware.
With this change you can correct that (works on PHP without nl_langinfo support).
Add this function:
| Code: | function find_date_format() {
// for *nix platforms, and PHP >= 4.0.7, use nl_langinfo information
if (version_compare(phpversion(), "4.0.7") != -1 && function_exists("nl_langinfo") && substr(php_os, 0, 3) != "WIN") {
return str_replace(array('E', 'B'), array('D', 'M'), strtoupper(preg_replace('/[^a-z]/i', '', nl_langinfo(D_FMT))));
}
// *** if nl_langinfo is not available, do it the hard way ;-)
// find the date separator
$date_separator = preg_replace('/[a-zA-Z0-9]/i', '', strftime("%x"));
// if a separator has been found
if (!empty($date_separator)) {
// get the different fields from the date
$date_fields = explode($date_separator{0}, strftime("%x"));
// if we found 3 parts in the date string
if (count($date_fields) == 3) {
// possible values
$days = array(strftime("%d"), strftime("%e"));
$months = array(strftime("%m"), strftime("%b"), strftime("%B"));
$years = array(strftime("%Y"), strftime("%y"));
// part 1
if ($date_fields[0] == $date_fields[1]) {
// month and date the same, then assume MD if the locale uses am/pm, or DM otherwise
$format = strftime("%p") == "" ? "D" : "M";
} elseif (in_array($date_fields[0], $days)) {
$format = "D";
} elseif (in_array($date_fields[0], $months)) {
$format = "M";
} elseif (in_array($date_fields[0], $years)) {
$format = "Y";
}
// part 2
if ($date_fields[0] == $date_fields[1]) {
// month and date the same, then assume MD if the locale uses am/pm, or DM otherwise
$format = strftime("%p") == "" ? "M" : "D";
} elseif (in_array($date_fields[1], $days)) {
$format .= "D";
} elseif (in_array($date_fields[1], $months)) {
$format .= "M";
} elseif (in_array($date_fields[1], $years)) {
$format .= "Y";
}
// part 3
if (in_array($date_fields[2], $days)) {
$format .= "D";
} elseif (in_array($date_fields[2], $months)) {
$format .= "M";
} elseif (in_array($date_fields[2], $years)) {
$format .= "Y";
}
}
}
// return the format detected, or YMD if detection failed
if (isset($format) && strlen($format) == 3) {
return $format;
} else {
return "YMD";
}
}

Then find:
| Code: | | $field_order = "MDY"; |
and replace it by:
| Code: | | $field_order = find_date_format(); |
This code is tested on Linux and Windows, with different versions of PHP4. I haven't had any failures sofar, and you can still use the field_order parameter to override the detection (although I think with this addition, who needs it?  ) |
