arjanvr Posted September 27, 2013 Share Posted September 27, 2013 How do I change the date format so it reads Day-month-Year (example 13-05-2013) in the output and allows me to put it in that format in the input form.. I read a couple of pages how to do it but that did not work so I hope someone can either fix it for me or tell me exactly what to change so i can learn from that.. much appriciated The input and edit form <?php /* Staat de gebruiker toe om nieuwe records toe te voegen te bewerken */ // connect to the database include("connect-db.php"); // Maakt nieuw/edit record formulier function renderForm($klantnummer = '', $bedrijfsnaam ='', $adres ='', $postcode ='', $plaats ='', $londerhoud ='', $aantal ='', $vonderhoud='', $error = '', $id = '') { ?> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> <title> <?php if ($id != '') { echo "Bewerk onderhoud"; } else { echo "Nieuw onderhoud"; } ?> </title> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> </head> <body> <h1><?php if ($id != '') { echo "Bewerk onderhoud"; } else { echo "Nieuw onderhoud"; } ?></h1> <?php if ($error != '') { echo "<div style='padding:4px; border:1px solid red; color:red'>" . $error .

Ch0cu3r Posted September 27, 2013 Share Posted September 27, 2013 What/where is your date field? How is the date stored in your database? Functions you'll want to look at are date and/or strtotime (depening on how you're storing the date).

cyberRobot Posted September 27, 2013 Share Posted September 27, 2013 If the date comes from your database and the field type in the database is one of the date types, you could use SQL's DATE_FORMAT() function: http://dev.mysql.com/doc/refman/5.1/en/date-and-time-functions.html#function_date-format Link to comment https://forums.phpfreaks.com/topic/282471-how-to-change-date-format/#findComment-1451385 Share on other sites More sharing options...
arjanvr Posted September 27, 2013 Author Share Posted September 27, 2013 What/where is your date field? How is the date stored in your database? Functions you'll want to look at are date and/or strtotime (depening on how you're storing the date). These are date fields and they are stored in the database as type Date in edit/add form. <strong>Laatste onderhoud:<br><small>jaar-maand-dag</small></strong> <input type="text" name="londerhoud" value="<?php echo $londerhoud; ?>"/><br/> <strong>Volgende onderhoud:<br><small>jaar-maand-dag</small></strong> <input type="text" name="vonderhoud" value="<?php echo $vonderhoud; ?>"/><p/> $londerhoud = htmlentities($_POST['londerhoud'], ENT_QUOTES); $vonderhoud = htmlentities($_POST['vonderhoud'], ENT_QUOTES); Although now I see mixed up the 2 forms I have so the bottom field is from a different form but the they are the same way build so if i know how to do one of the 2 I can do the other myself.. This is also a date which needs to be changed echo "<td>" . $row->vervaldatum . "</td>"; Link to comment https://forums.phpfreaks.com/topic/282471-how-to-change-date-format/#findComment-1451460 Share on other sites More sharing options...
Ch0cu3r Posted September 27, 2013 Share Posted September 27, 2013 In what format is the date currently formatted for $_POST['londerhoud'] and $_POST['vonderhoud']? I will also reiterate which function you'll need to use a I said earlier. Functions you'll want to look at are date and/or strtotime (depening on how you're storing the date).

arjanvr Posted September 28, 2013 Author Share Posted September 28, 2013 Select date in format day-month-Year (01-01-2001) from a date column. SELECT DATE_FORMAT(date_column,'%d-%m-%Y') AS date FROM table Does it matter where I place that on the page or does it need to be in the line where I actually print the date. Does that work for both the input form to put into the script aswell as the script that displays it on the page or do I only need it to put it correctly into the database and I can simply keep the echo as is?

cyberRobot Posted September 30, 2013 Share Posted September 30, 2013 Does it matter where I place that on the page or does it need to be in the line where I actually print the date. Does that work for both the input form to put into the script aswell as the script that displays it on the page or do I only need it to put it correctly into the database and I can simply keep the echo as is? It's a MySQL function, so it goes in the query where you get the date fields from the database.
