I have $year and $month as two variables. I want to convert them into date so that I can insert it into mysql table. I just want to store mm-yyyy in mysql.Is it possible in php?
$date = "$year-$month-01";
If you plan on storing it in a real 'date' field, you must have a day of the month too.
MySQL displays DATE values in ‘YYYY-MM-DD’ format.
So if you want it as a DATE, you have to put a day in your date like : $date = "$year-$month-$day".
If you don't want it as a DATE, you can store it as a 'MM-YYYY' like that : $date = "$month-$year".
After, you just have to make your MYSQL Query and it will work.

I have created the text box as well as the query for database.But in my case I want to fetch the data from input field and store it in database.
What actually happens is when I use the function $_POST['launch_date'] it displays the date that I add in db but when I store this in a variable and convert it to y-m-d format it doesn't give me the answer from the text field like $launch_date=date("Y-m-d",strtotime($_POST['launch_date']));.
when i print the both the above mentioned code in single line like echo $_POST['launch_date'] .$launch_date."<br>"; I get the following results
30/01/2020 1970-01-01.
The first one is from my text box and the second one is from the variable that I have created.
Use DateTime::create_from_format() to specify the format of your dates.
$launch_date = DateTime::create_from_format('m/d/Y', $_POST['launch_date'])->format('Y-m-d');
$_POST['launch_date'] = '30/01/2020';
$date = str_replace('/', '-', $_POST['launch_date']);
$launch_date = date('Y-m-d', strtotime($date));
echo $_POST['launch_date'] ." ".$launch_date."<br>";
Output: 30/01/2020 2020-01-30
The issue here is that the / has confused the format of m/d/Y (instead of d/m/Y). And if the date time is not valid (for instance, the month is greater that 12) is in the American format, you'll get the default time (aka UNIX timestamp 0) ie 1970-1-1.
You can create date from user input by
$launch_date = DateTime::create_from_format('d/m/Y', $_POST['launch_date'])->format('Y-m-d');
This is create a date variable of the form Year-Month-Date.
You can change the format as per your requirement.
Y-m-d is the standard date format for MySql.
If You are using PHP version 5.2 or lower you , you will have to parse the date in to 'd'. 'm' and 'y' . Then you will have to create a new date.
I have a MySQL table containing date and time in one of its column as text (15/05/2018 11:05:40). I want to convert this string to DateTime format so that it can be used to fetch data based on the date in PHP.
Use DateTime::createFromFormat
$date = date_create_from_format('d/m/Y H:i:s', $time);
I have a calendar in html form and I want to insert this date into MySQL. The default MySQL date is 0000-00-00. But in my country the format is DD/MM/YYYY. So what to do to fix it. Thank you. I am using PHP.
You must use one format in your HTML page, and another format in your database.
So, if you want to store a date like this '12/05/2008' into mySql, you must transform it like this:
$date = '12/05/2008';
$dateToStore = date('Y-m-d', strtotime(str_replace('/','-',$date)));
And if you wonder why, you need to replace the '/' with '-' to make php know that the first part of the data string is the day, and then the month (as I think is your case).
MySQL the date format is always YYYY-MM-DD. To convert it to another format, you need to manually convert the retrieved date to the desired format like
$displayDate=date("d/M/Y", strtotime($mysqldate));
Method 1
You cant insert into DD/MM/YYYY format. Instead while rendering it in view file you can change into desired format.
<?php
$date = $result['db_date']; // I ASSUMED YOUR DB FIELD IS db_date
$desiredFormat = date('d/m/Y', strtotime($date)); // CONVERTING INTO YOUR FORMAT
echo '<pre>'; print_r($desiredFormat); // DISPLAYING IT
?>
Method 2
You can retrieve from database in your desired format using below
SELECT *, DATE_FORMAT(YOUR_DATE_FIELD, "%m/%d/%Y") AS date FROM YOUR_TABLE;
Use MySQL STR_TO_DATE
Try this mysql query :-
INSERT INTO `table`(`date`) VALUES (STR_TO_DATE('10/10/2015', '%d/%m/%Y'))
I want to convert the data on which I have the format
$dateToday = date("d-m-Y");
so the value of $dateToday is 27-12-2012
Then I want to save it to the database with the mysql data type date. How to keep the value of 27-12-2012 it can be stored in the mysql database with the format 2012-12-27?
Help me please. Thank you
Yes, you can convert the date with strtotime();
$dateToday = date("d-m-Y");
$newDate = date("Y-m-d", strtotime($dateToday));
OUTPUT: 2012-12-27
And then you can store data to your database.
When you have to recover the date you can reverse this operation like this:
$dateFromDatabase = "2012-12-27";
$reverseDate = date("d-m-Y", strtotime($dateFromDatabase));
OUTPUT: 27-12-2012
(corrected "Y-m-d" to "d-m-Y" in 2nd date call)
this is how it works:
You have to store your data in the proper mysql format. It will allow you to make whatever ordering, aggregating, filtering and calculating your dates.
But when you need to display your data, you may convert it in whatever format you wish, using mysql DATE_FORMAT() function:
SELECT DATE_FORMAT(dt,'%d-%m-%Y') as dtf FROM TABLE
will give you dtf field formatted in your custom format
i'll show u how to do that.
To explain i create one table called testtable1 it contain only one column called
col1 of type DATE
Table creation query is given below
CREATE TABLE `testtable1` (
`col1` DATE NULL DEFAULT NULL
)
Following query will work as you need.
In the first line i declared a string variable. In the second line i converted that string to your required date format and inserted into table.
set #var1='27-12-2012';
insert into testtable1 values(STR_TO_DATE(#var1, '%d-%m-%Y'))
You could also try to use the mysql function for converting to a date from a string, i.e
STR_TO_TIME
.
The SQL query could be
INSERT INTO foo_table (foo_date)
VALUES (STR_TO_DATE('27-12-2012','%d,%m,%Y'))
If you want to store data in MYSQL table in this format, you need to declare the column as varchar.
Because the datetime store date in a different format like 'yyyy-mm-dd hh:mm:ss'
The output is wrong This cannot show the date from the database .This show 1970/01/01.....
$date=Date($year."/". $month."/". $day);
$date=Date("Y-m-d", strtotime($date));
echo $date;enter code here
Try this
$dateToday = date("d-m-Y");
$dateForMysql = date('Y-m-d', $dateToday));
So im trying to insert a time using an input text field into a database table with data type TIME.
The format of time that I want to insert should be like this:
H:MM pm// example: 6:30 pm
The problem is the am/pm doesnt insert in my database table.
Only the hour and minute.
Please give me idea how to solve this.
Better with sample codes. Thanks.
Data Type TIME is for storing time data type - that means no AM/PM. Store the data in Your database in 24 hour format and format it to 12 hour format with am/pm in PHP or MySQL using one of these:
PHP:
$date = new DateTime($mysql_column['time']);
$date->format('h:i:s a');
or:
$date = date('h:i:s a', strtotime($mysql_column['time']));
or MySQL:
SELECT DATE_FORMAT('%h:%i:%s %p', time) FROM table;
Store the TIME as a standard format (18:30:00), and the format it however you want when you display it (Using DateTime objects or the date functions).
MySQL doesn't support extra formats when storing time data.
I think you want to add the jquery time picker value in your database with actual format in the database.
Here I have written some function
function update_time($time){
$ap = $time[5].$time[6];
$ttt = explode(":", $time);
$th = $ttt['0'];
$tm = $ttt['1'];
if($ap=='pm' || $ap=='PM'){
$th+=12;
if($th==24){
$th = 12;
}
}
if($ap=='am' || $ap=='AM'){
if($th==12){
$th = '00';
}
}
$newtime = $th.":".$tm[0].$tm[1];
return $newtime;
}
$time = update_time($_POST['time']); //here I am calling the function now you can insert the value in db
you just have to call the function and insert the returned value in database.
And while printing that you can do something like that echo date("h:i A",strtotime($time));
Change the type of the field to a varchar. TIME cannot store it like that. However, keep in mind that storing it like you want to will make it more difficult to provide localized results if that is something you will eventually need. That is, timezone support becomes difficult if you are not storing the timestamp itself, but rather a user-friendly representation.
EDIT: Or, DATETIME works as well, as was pointed out in the comments above.
You can use the DateTime Object in PHP which has functions to create a time object from any format and also has a function to output a time in any format like so
<?php
$date = DateTime::createFromFormat('j-M-Y', '15-Feb-2009');
echo $date->format('Y-m-d');
?>
http://php.net/manual/en/datetime.createfromformat.php
You would be best changing the field type to 'VARCHAR (32)', and then writing the time with PHP.
Example: date('m/d/y g:i:sa');
Why do you want to store the am or pm anyhow? If you store the date/time as a unix epoch timestamp, you can format the date however you want in the program - not the database.
Example: time(); - Store this in an INT(8) field.
date('m/d/y g:i:sa, $time()); - Output from DB like this.
try .ToShortTimeString() after your date variable.
