kannuk Posted January 12, 2011 Share Posted January 12, 2011 Hi - I have been searching for a way to select the stored time from a database (stored in 24h format - 13:20:00) and display it as 12h format. I have checked a number of forums and nothing quite seems to fit the bill. I would like it to display as 2:00pm, 12:00am, etc. Here is what I have so far: $sql = ('SELECT * FROM events WHERE active="1" AND event_date >= CURRENT_DATE AND MONTH(event_date) = 1 order by event_date ASC, event_start ASC'); $result = mysql_query($sql); $num_rows = mysql_num_rows($result); // Yes Item if (!($num_rows == 0)) { $myrow = mysql_fetch_array($result); echo ('<span class="bold" style="font-size:14px">January</span>'); do { printf ('<span>Event Time: %s', $myrow['event_start']); if ($myrow['event_end'] != '') { printf (' to %s', $myrow['event_end']); } } while ($myrow = mysql_fetch_array($result)); } Right now this just shows the regular 24h format (hh:mm:ss) for any events in the month of January. I would like both "event_start" and "event_end" to show up in 12h format. I have tried a number of things but none of it works. I'm SURE it is something simple that I have missed. Thanks in advance for any help. Quote Link to comment Share on other sites More sharing options...
litebearer Posted January 12, 2011 Share Posted January 12, 2011 Have you tried ... http://www.php-mysql-tutorial.com/wikis/php-tutorial/php-12-24-hour-time-converter-part-1.aspx Quote Link to comment Share on other sites More sharing options...
Pikachu2000 Posted January 12, 2011 Share Posted January 12, 2011 Select it in your query already formatted using the MySQL DATE_FORMAT() function. Quote Link to comment Share on other sites More sharing options...
kannuk Posted January 12, 2011 Author Share Posted January 12, 2011 Hey - thanks for the feedback. litebearer, I am having a hard time getting my head around what to do with that code. I am not that experienced at PHP so I am sort of drawing a blank. Pickachu2000 - I have been trying to include DATE_FORMAT in the query but it is not working (at least not how I am doing it. Doesn't this have to be done below where the information is printed out, not in the query? Here is what I tried to include in the query: DATE_FORMAT(event_start, '%r'). I also tried with TIME_FORMAT. Sorry I'm just not getting it. Quote Link to comment Share on other sites More sharing options...
Pikachu2000 Posted January 12, 2011 Share Posted January 12, 2011 Actually, I guess I should ask what the data type of the field is that the time is stored in. Is it a DATETIME field, or something else? Quote Link to comment Share on other sites More sharing options...
kannuk Posted January 12, 2011 Author Share Posted January 12, 2011 Hi Pickachu - It's TIME. Sorry, I thought I stated that upfront. Stored as 00:00:00 (h/m/s) 24 hour format. Quote Link to comment Share on other sites More sharing options...
litebearer Posted January 12, 2011 Share Posted January 12, 2011 simply put the function near the top of your page; then fill the variable with the data from your db table (see the last couple of lines) <?php function TimeCvt ($time, $format) { # $time - String: Time in either 24hr format or 12hr AM/PM format # $format - Integer: "0" = 24 to 12 convert "1" = 12 to 24 convert # RETURNS Time String converted to the proper format if (ereg ("[0-9]{1,2}:[0-9]{2}:[0-9]{2}<wbr />", $time)) { $has_seconds = TRUE; }else{ $has_seconds = FALSE; } if ($format == 0) { // 24 to 12 hr convert $time = trim ($time); if ($has_seconds == TRUE) { $RetStr = date("g:i:s A", strtotime($time)); }else{ $RetStr = date("g:i A", strtotime($time)); } }elseif ($format == 1){ // 12 to 24 hr convert $time = trim ($time); if ($has_seconds == TRUE){ $RetStr = date("H:i:s", strtotime($time)); }else{ $RetStr = date("H:i", strtotime($time)); } } return $RetStr; } $bad_time = "14:32:11"; /* the value from your db table */ $format = 0; $good_time = TimeCvt ($time, $format); ?> Quote Link to comment Share on other sites More sharing options...
Pikachu2000 Posted January 13, 2011 Share Posted January 13, 2011 While that will work, I would think this would be quite a bit less hassle. "SELECT TIME_FORMAT(`event_start`, '%l:%i %p') AS `s_time`, TIME_FORMAT(`event_end`, '%l:%i %p') AS `e_time` . . . etc. The formattted times can then be accessed directly as $myrow['s_time'] and $myrow['e_time'].
