PHP - Selected Date Sums Values Month And Day

Hi,   I'm new to php,   I'm trying to get the month value from a date stamp (ie I have a variable with the following sort of value: 2014-08-20 07:32:20 )   how do I create a new variable with just the month values (ie 08) of the date stamp??   any help would be appreciated.   Thanks !

Hello,
I've been struggling for days on this problem now. And I'm getting frustrated!  I know that the answer is simple, and I've done it before but I cannot figure out what I'm doing wrong.
What do I want?
Well, I get a date from the database in this format: YYYY-MM-DD. I first want to distract one month from that and then set in into this form: YYYY, MM, DD. I've got this but it's not working (I've tried a lot different values).

$transformdate = date("Y-m-d", strtotime("-1 month", $d_datevalue)); 
$startpoint = str_replace("-", ", ", $transformdate);


Thanks,

date in my database is save as (dd/mm/yyyy). now i want to create sql to search for activity for chosen month..how do i extract month from (dd/mm/yyyy) and include in sql?

Hi, I'm having trouble with this:

Code: [Select]
$date = date('d/m/y') ;
echo $date;
echo "<br/>";
$date1 = strtotime('date -1 month');
echo date('Y-m-d', $date1);
My result looks like this:
Current Date:  19/05/11
Date minus 1 month:  1970-01-01

I want it to look like this:
Current Date:  19/05/11
Date minus 1 month:  2011-04-19

Hi Guys,

Been a while since I've been on here,  but I'm currently bashing my head against a wall trying to figure this one out.

Basically I have a calendar that outputs Monday through Sunday, and the user clicks on a date and outputs it to the URL.... ie. ?day=$day&month=$month&year=$year.

Now the next part I need to find out what day (0-6) say the 25th Feb 2011 will be wday 5... now how can I do this in code?

And before anyone says why not output it to url, I cannot as the first week and last weeks use different code

Cheers

James

i have this code to set a date to the 1st of the previous month --

SELECT DATE_FORMAT(DATE_SUB(tbl_col, INTERVAL 1 MONTH), '%Y-%m-01') FROM table

can it be changed to set date to first Monday in that month...?

I am currently trying to make a line graph out of data using php and javascript. How do I add up the values of a column and separate them by month. For example the database has 74 amount of rows. Then the values from the "views" column get added up and then displayed by month.

Code: [Select]
   <table width="70%" class="linechart">
     <thead>
       <tr>
         <td></td>
         <th scope="col">Jan</th>
         <th scope="col">Feb</th>
         <th scope="col">Mar</th>
         <th scope="col">Apr</th>
         <th scope="col">May</th>
         <th scope="col">Jun</th>
         </tr>
       </thead>
     
     <tbody>
       <tr>
         <th scope="row">Post Views</th>
         <td>24324</td>
         <td>29634</td>
         <td>15435</td>
         <td>56545</td>
         <td>23543</td>
         <td>2123</td>
         </tr>
         
       </tbody>
   </table>

Hi,

I've got a date picker on a form which puts data into a database in the YYYY-MM-DD format. Just wondering how I could also put the name of the month (extracted from that) as well as just the year into separate columns. Ie: To use the field race_date from the form to also fill the 'race_month' and 'race_year' columns in the database.

This code obviously only fills the 'race_date' column so far:
Code: [Select]

global $_POST;

$race_date = $_POST["race_date"] ;


....



$query = "INSERT INTO 10k_races (race_date, race_month, race_year)" . "VALUES ( '$race_date', '$race_month',  '$race_year')";

I have a php page where i need to list all item in a particular month.But the format for date stored is MMMM DD,yyyy that January 22, 2011.
How do i extract the month name only from the above format

I am using the following code to get the third sunday of every month for +6 Months from todays date.  I have put together the following code which works perfectly when the date is echoed however when it comes to inserting those dates into mysql db it throws a unable to convert to string error.  Im new to this and my head is in a spin as to why those dates can't be inserted if they can echoed ok.  I have spent 2 days at it now and searched many forum however they seem to get side tracked from my issue (or do they)??????? I figure I can't go mixing DateTime and date() the way I have?  Please help???

Code: [Select]
[php]
$month=date('F');
$now=date('Y-m-d');
$year=date('Y');

$num='3'; //example only this will be a $_POST value 0-3
$day='Sunday'; //example only this will be a $_POST value Monday-Sunday

$start= date('Y-m-d', strtotime('+'.$num.' week '.$day.' '.$month.' '.$year.''));

if($start>$now) {
$begin=strtotime('+'.$num.' week '.$day.' '.$month.' '.$year.'');
} else {
$d = new DateTime( $start );
$d->modify( 'first day of next month' );
$nextmonth = $d->format( 'F' );
$year = $d->format( 'Y' );
$begin=strtotime('+'.$num.' week '.$day.' '.$nextmonth.' '.$year.'');
}

$date=date('Y-m-d', $begin);
# insert into db first occurance
//mysql_select_db($database);
//$query_rsFirst = "INSERT INTO event_date VALUES (NULL, '$event', '$d', '$date', '$date')";
//$rsFirst = mysql_query($query_rsFirst) or die(mysql_error());
echo $date.'<br/>';
for($i = 0; $i <= 4; $i++)  {
$d = new DateTime( $date );
$d->modify( 'first day of next month' );
$nextmonth = $d->format( 'F' );
$date=date('Y-m-d', strtotime('+'.$num.' week '.$day.' '.$nextmonth.' '.$year.''));

# insert into db
//mysql_select_db($database);
//$query_rsDate = "INSERT INTO event_date VALUES (NULL, '$event', '$d', '$date', '$date')";
//$rsDate = mysql_query($query_rsDate) or die(mysql_error());
echo $date.'<br/>';
if($nextmonth=="December") {
$d = new DateTime( $date );
$d->modify( 'first day of next year' );
$year = $d->format( 'Y' );
}
}

I have set up a function to validate user input date in yyyy-mm-dd format taking into account the following possibilities: the length of the month February 29th when the year is not a leap year When I run the code, I do not get any feedback whatsoever, when it should. This is the code below and I would appreciate your thoughts:

if(!function_exists('checkdate'))
{
	function checkdate($date, $checkyear, $currentmonth)
	{
		if($checkyear == 0)//if it is not a leap year
		{
			// if current month is february
			if($currentmonth == 2)
			{
				if(!preg_match("/^(20)\d\d[-](0[1-9]|1[012])[-](0[1-9]|1[0-9]|2[0-8])$/", $date))
				{
					// set error for date field
					return ($error = 'Invalid Date!');
				}
				return ($error = 'valid Date!');
			}
			// if current months are april, june, september or november
			elseif($currentmonth == 4 || $currentmonth == 6 || $currentmonth == 9 || $currentmonth ==11)
			{
				if(!preg_match("/^(20)\d\d[-](0[1-9]|1[012])[-](0[1-9]|1[0-9]|2[0-8]|3[0])$/", $date))
				{
					// set error for date field
					return ($error = 'Invalid Date!');
				}
				return ($error = 'valid Date!');
			}
			else
			{	
				if(!preg_match("/^(20)\d\d[-](0[1-9]|1[012])[-](0[1-9]|[12][0-8]|3[01])$/", $date))
				{
					// set error for date field
					return ($error = 'Invalid Date!');
				}
				return ($error = 'valid Date!');
			}
		}
		elseif($checkyear == 1)//if it is a leap year
		{
			// if current month is february
			if($currentmonth == 2)
			{
				if(!preg_match("/^(20)\d\d[-](0[1-9]|1[012])[-](0[1-9]|1[0-9]|2[0-9])$/", $date))

	}
$todate = getdate();

$checkyear = date('L');
$date = 2014-02-31;
echo checkdate($date, $checkyear, $currentmonth);

I'm creating a line graph using ChartJs. I wanted to display my data according to the month selected by the user. For example, if the user select "2021-03" all the order that is made in the month of March will be plotted in the graph. It works well for the current month, but it does not work for the selected month. 

I use Ajax to get the data but i do not know why my graph does not shown when i click on my `loadchart();` button. Can anyone enlighten me how can i do it? Because i do not know what mistake did i made here. Any kind of explanation will be appreciated. Thanks!

 

This is the where i place my `loadchart()` button and also the javascript to plot the graph.

  <div class="col-md-12 form-group">

I have created a query to show the subject name as a drop down box now I would like to you use value to compare what module available in the database.

For now I can disaplyed all the module that is avilable for all the subject. But i would like to use the drop down box to gather which subject they have chosend then use this information to gather the module

$query=("SELECT Tes_Name FROM User u, Subject s, Test t WHERE u.Use_ID = '{$_SESSION['ID']}'
    
    AND s.Sub_ID=t.Sub_ID

I have this function where i want to pass the month and year according to the date drop down that is chosen by the user. But can't seem to get the selected month and year. But instead, i got the month and year for now (which is April 2020). Can any one show me how can i achive this? I mean how can i pass the month and year selected to my `allreport-summary.php` page. It would be better if you guys can show me examples of codes on how can i implement this. Any help will be appreciated. Thank you so much. cheers! 

   

  <div class="row">
                  <div class="col-4 my-auto">
                    <input type="month" id="month" class="form-control" value="<?php echo date('Y-m'); ?>">
                  </div>
                  <div class="col-4 my-auto">
                    <select class="form-control" id="seller">
                      <option value="">Select All</option>
                      <?php
                      $sql = "SELECT * FROM sellers ORDER BY seller_registered";
                      $query = $conn->query($sql);
                      while ($row = $query->fetch_assoc()) {
                      ?>
                      <option value="<?php echo $row['id'];?>"><?php echo $row['seller_fullname'];?></option>
                      <?php } ?>
                    </select>
                 
                  </div>
                  <div class="col-4">
                    <button type="button" class="btn btn-info" onclick="loadreports();">
                      <i class="nc-icon nc-zoom-split"></i>
                    </button>
                  <a href="allreport-summary.php?month=<?php echo date('Y-m');?>">
                    <button type="button" class="btn btn-info" style="height: 40px;">
                      <i class="fa fa-file-excel-o"></i> &nbsp;  &nbsp;Export All Report
                    </button>
                   </a>
                      </div>

how can i pass that `<a href="allreport-summary.php?month=<?php echo date('Y-m');?>">` according to the selection of `  <input type="month" id="month" class="form-control" value="<?php echo date('Y-m'); ?>">` ? 

I am working on a report generation. Here I need to count the number of months involved in the selected date range. I need to apply the monthly charges accordingly.

Example: If the user selects 25-08-2011 to 03-10-2011, it should return 3 as the number of months.

Yes, the number of days are less than 60 but still the date range is spread across 3 months.

Any solution.. Please.
