PHP - Help With Php Dates

Hi guys,

I am trying to create a program which manages campaigns.
each campaign has a start date and and end date.
a user has to enter data releated to the campaign everyday

example
start date: 10-1-2011
end date: 17-1-2011

now all this information is stored in 2 tables
1st table is "campaigns" this stores the campaign name, start date and end date
and 2nd table is "campaign_data" this table stored the data for each campaign and also date of when that data was entered

my question is, if the user did not enter data on 11-1-2011 how will I know this, keeping in mind the month diffrence which can accur if the length of the campign was 2 month long?


table:
campaigns
fields:
id | campaign_name | start_date | end_date

table:
campaign_data
fields:
id | campaign_id | date | page

Thank you

Hi, I have a created comment system, now what i am after is when the comment is posted the time is posted in hidden format. All is going fine but what i don't know, what should the time be posted as example date(H:m:s) or... the result i want is time in minutes first e.g.
commented 2 mins ago and increasing to hours after that days. Could some one kindly guide me in the right directions.

how do I order two tables by date so that the most recent are first and the most unrecent last?  like table 1 should be first then a table 2 then a table 1.  does this make sense?

Hi again!
I'm trying to use this code that i found somewhere in the net to display all the dates between 2 dates.
It is exactly what i need but..
I understand the code and its structure (i think) but it gives me an error (maximum execution time of blah blah) which i think is
because it makes an infinite loop(not sure..  )

Code: [Select]
function GetDays($sStartDate, $sEndDate)
{   
$sStartDate = gmdate("Y-m-d", strtotime($sStartDate)); 
$sEndDate = gmdate("Y-m-d", strtotime($sEndDate)); 
       
     $aDays[] = $sStartDate; 
     
     $sCurrentDate = $sStartDate; 
     
      while($sCurrentDate < $sEndDate){ 
        $sCurrentDate = gmdate("Y-m-d", strtotime("+1 day", strtotime($sCurrentDate))); 
     
        $aDays[] = $sCurrentDate; 
      } 
     
      return $aDays; 
    } 


Appreciate the help and suggestions!
Gonna browse the forums for answers for the meantime...

Hi There,

I am trying to create a table, and accross the top I would like the Week Commencing Dates of the last 5 weeks. So for example:

<table>
<tr><td>07/02</td><td>31/01</td><td>24/01</td><td>17/01</td><td>10/01</td></tr>
</table>

Can anyone help?

Cheers
Matt

Been a while since I hit a snag but have a new one!

I have hit the old problem that I need to be able to input dates pre 13th December 1901 which appears to not work when using strtotime
<?php echo date("F j, Y ", strtotime($row_seasonview['season_start'])); ?>

Following a bit of googling it seemed that the alternative was to set the format in the query
Code: [Select]
SELECT *,
DATE_FORMAT(`season_start`,'%D %M %Y') AS startdate,
DATE_FORMAT(`season_end`,'%D %M %Y') AS enddate
FROM seasons
WHERE season_id = %sand to call the date from that
<?php echo $row_seasonview['startdate']; ?>
but this just comes back with 'Query was empty'. If I remove the two DATE_FORMAT lines the query runs fine.

I know there must be a way round this but cannot fathom it out. Any suggestions would be greatfully welcomed!!!

Thanks in advance
Steve

Code: [Select]
<?php
$date = date('Y-m-d');
$strtime = strtotime('today +14 days'); 
$strtime = date('Y-m-d', $strtime);
if ($distributor != 1) {
$select = "SELECT deal_data.headline AS headline FROM deal_data
WHERE str_to_date(deal_data.end_date,'%Y/%m/%d') BETWEEN str_to_date('" . $date . "', '%Y/%m/%d') and str_to_date('" . $strtime . "', '%Y/%m/%d')";
}else {
$select = "SELECT deal_data.headline AS headline FROM deal_data
WHERE str_to_date(deal_data.end_date,'%d.%m.%Y') BETWEEN '" . $date . "' and '" . $strtime . "'";
}
?>
The dates are formatted in the database as Varchar (I don't do that anymore, this is an old project) and are formatted as: "09/12/2010".

Anything wrong with the above code that would make it not work and return queries?

Hi,

I'm trying to get the date, using this code


<?php
include('config.php');
$today = date('Y-m-d 00:00:00');
$nineyesterday = date('Y-m-d H:i:s', mktime(date("H") - (date("H") + 6), date("i") - date("i"), date("s") - date("s"), date("m") , date("d"), date("Y")));
$now = date('Y-m-d H:i:s');
$nineam = date('Y-m-d 9:00:00');
$ninepm = date('Y-m-d 18:00:00');

if ((strtotime($now) >= strtotime($today)) &&  (strtotime($now) <= strtotime($nineam)))
{
//count the answers by yes or no
$q = "SELECT opt, count(opt) FROM plus_poll_ans WHERE date<='".$nineyesterday."' AND date>='".$nineam."' GROUP BY opt desc "; 
}
elseif ((strtotime($now) >= strtotime($nineam)) &&  (strtotime($now) <= strtotime($ninepm)))
{
//count the answers by yes or no
$q = "SELECT opt, count(opt) FROM plus_poll_ans WHERE date<'".$nineam."' AND date>='".$ninepm."' GROUP BY opt desc "; 
}
$q = mysql_query($q) or die(mysql_error());

//separate the results
while($row = mysql_fetch_array($q))
{
$total_opt[] = $row['count(opt)'];
}

mysql_freeresult($q);

$yes = intval($total_opt[0]);
$no = intval($total_opt[1]);

$total = $yes + $no;
        echo $total."<br/>";
        echo $yes."<br/>";
        echo $no."<br/>";
?>


but it didn't work, why isn't it working?

Thanks

I was just wondering if anyone can reccomend the best way to get dates from a database and turn them into dates you can display.  For example if you have a date stored such as 23/08/10, is there an easy way to turn this into 23rd August 2010?  Thanks for any help. 

so i have a basic html table and down the left column i have monday,tuesday,wednesday.... sunday.

In the column 2nd from the left, i want to fill it with the current weeks dates, which is really based on the current date. So if today is Jul 29th Friday, then strtotime("last monday") would give me Jul 26th Monday... my issue is "last monday" wont work if today is monday because that will give me 19th of july... and since I technically dont know what day is today i'm not sure how to cleanly work around this without having to use some if statement... if today is monday do "last monday +7 days" or just do "now" etc...

Thanks!

Evening All,

How would I go about selecting a future date based on a date?

What I want to achieve is to take todays date, add ten days to it and then store it as the month end following that date.

For example 19th Nov + 10days = 29th November = 31st Dec


Many thanks for any pointers!

Hello Everyone,

I seem to be going no place fast...

In a PHP file, I should be taking a date from a jquery datpicker, and get it to a format that mysql will read in the yy-mm-dd format with...

if(isset($_POST['choice']))
$choice = (isset($_POST['choice'])) ? date("Y-m-d",strtotime($_POST['choice'])) : date("Y-m-d");

Can't seem to get a single inline(embeded) jquery Datepicker date to post right to the PHP and mysql correctly to return data from the table.. My reading has me to understand it should be right, but it is not. Now the datepicker select does have several POST events to PHP that trigger from the single select... data being requsted in PHP by the day, month, and year as well as PHP to use the date to create a highcharts graph in the PHP file to select data for hours of a day, days of a month, and months of a year.

The Table is very simple... date, time, power

Here is the PHP for dayPower.php that will just collect the sum data for the selected day in the datepicker...

<?
if(isset($_POST['choice']))
$choice = (isset($_POST['choice'])) ? date("Y-m-d",strtotime($_POST['choice'])) : date("Y-m-d");
$con = mysql_connect("localhost","root","mackie1604"); 
if (!$con)  { 
die('Could not connect: ' . mysql_error()); 
} 
mysql_select_db("inverters", $con); 

$sql = 'SELECT sum(power) AS power '        
.'FROM feed '       
.'WHERE date = $choice';
$res = mysql_query($sql) or die('sql='.$sql."\n".mysql_error());
$row = mysql_fetch_assoc($res);
echo $row['power']; 
?>

Here is the javascript that sends the date and how it post the PHP file.

Code: [Select]
$(document).ready(function () {   
      $('#datepicker').datepicker({onSelect: function(dateText,inst) {
            var myDate = $(this).datepicker('getDate');
            $('#apDiv1').html($.datepicker.formatDate('DD, d', myDate));
            $('#apDiv5').html($.datepicker.formatDate('MM', myDate));
            $('#apDiv7').html($.datepicker.formatDate('yy', myDate));
            $.post('dayPower.php', {choice: inst.val()}, function(data) {
                $('#apDiv2').html(data).show();
            });
            $.post('dayGraph.php', {choice: inst.val()}, function(data) {
                  $('#apDiv4').html().show();
});
$.post('monthPower.php', {choice: inst.val()}, function(data) {
                $('#apDiv6').html(data).show();
            });
            $.post('monthGraph', {choice: inst.val()}, function(data) {
                  $('#apDiv9').html().show();
});
$.post('yearPower.php', {choice: inst.val()}, function(data) {
                $('#apDiv8').html(data).show();
            });
            $.post('yearGraph', {choice: inst.val()}, function(data) {
                  $('#apDiv10').html().show();
});
      }});
});

What am I doing wrong

Alan

I have this code that compares date times but im not sure if its correct.

if("2008-08-10 00:00:00.0" > strtotime("now")) {
        echo "here";
    }


The code echo's here, but it shouldn't because the time is less than the current time. Any ideas?

I'm trying to make a script to check a files date time and if its under so many seconds long the page will refresh.  here is what I've got.  I've been testing the output of the date() functions but when i do the math all i get is a 0.  where did i go wrong? is it just i can't do math with dates?  Thanks in advanced.

//if ( date ("m d Y H:i:s.") - date ("m d Y H:i:s.", filemtime($proFile)) <= 00 00 0000 00:00:04 ){ //this is where the magic should happen.
