To get the difference in minutes, choose MINUTE for the difference in hours, choose HOUR, etc. To get the difference in seconds as we have done here, choose SECOND. The unit argument can be MICROSECOND, SECOND, MINUTE, HOUR, DAY, WEEK, MONTH, QUARTER, or YEAR. To calculate the difference between the timestamps in MySQL, use the TIMESTAMPDIFF(unit, start, end) function. TIMESTAMPDIFF(SECOND, departure, arrival) AS difference Solution 1 (difference in days, hours, minutes, or seconds): You'd like to calculate the difference between the arrival and the departure. In the travel table, there are three columns: id, departure, and arrival.
$row = mysqli_fetch_array ($result, MYSQLI_ASSOC) Īnd as diafol mentioned.Timestamp and you want to calculate the difference between them. $q = "SELECT * FROM festivals WHERE id = $id LIMIT 1" You did not select anny page(Or whatever)'
#How do you do division with mysql code
This is the code I used in case anyone else want to use it. Thank you very much everyone and mostly "diafol" for helping me out.
The template/festival.php file could be something like this. $description = 'This is a description of the page for the meta content' $_error_msg = "Sorry, this festival doesn't exist. You just access each one like this.īy using mod_rewrite in Apache, you could even get these urls to look something like.īut anyway, they'd all resolve to give you a GET id, which could be used in the following fashion. mysqli_insert_id($con) ĭocument.getElementById("festivals").submit()Īgain, I don't know why you're creating a physical file for each festival - it doesn't make sense. Mysqli_query($connection, "INSERT INTO festivals (id, festival_name, city, deadline, url) VALUES (?'festival_name', 'city', 'deadline', 'url')") Įcho "The added festival\'\s name is: $festival_name '' and has this id:". $fp = fopen($festivals_path.$php_file_name, "w") Now lets write this to the festivals directpry. We use the festival name to create a new file. $new_festival_file = str_replace($placeholders, $data, $tpl) $tpl = file_get_contents($tpl_patch.$tpl_file) Store template placeholders in an array. $result = $mysqli->query("SELECT festivals WHERE festival_id = $id") $id =1 //Default record to show if a problem.
Please let me know what I'm doing wrong here: My code wa way to long, so I cut it down to a few field. I think i might be duplicationg some of the code or just coding wrong.īecause when i visit that page on the net it doesn't show at all. Now, I have spent all the daytrying to get my code work. DO NOT REFRESH THE PAGE or data will be sent again." "VALUES('$name', 'NULL', '$logo', '$country', '$city', '$deadline', '$date_from', '$venue', '$date_to', '$info_page', '$web', '$about', '$open_for', '$flag')") or die(mysql_error()) Įcho "Thank You the form have been entered in the database. Mysql_query("INSERT INTO festivals (name, id, logo, country, city, deadline, date_from, venue, date_to, info_page, web, about, open_for, flag)". Insert the values into the correct database with the right fields. What changes do I need to do here? Unable to select database") Here is the code I use to post the form to the database.
