PHP - Php/mysql Dates

I am trying to create a simple calendar where a user can add/remove their availability date. This part works so far. Now what I am having trouble with is highlighting the already selected dates that are fetched from a MySQL database.

 

Here's my code.

// HTML
<div id="datetimepicker1"></div>

// Jquery/Ajax

<script>
$(document).ready(function () {

  $('#datetimepicker1').datepicker({
    dateFormat: "yy-mm-dd",
    multidate: true,
    onSelect: function () {
        var getDate = $("#datetimepicker1").val();

        $.ajax({
             type: "POST", //or GET. Whichever floats your boat.
             url: "snippets/adapter-set.php",
             data: { date: getDate },
             success: function(data) {
              // alert(data);
             },
             error: function() {
                 alert("Error.");
             }
        });
    }
  });
});
</script>

// PHP
// adapter-set.php

$post_date = $_POST['date'];

$find_query = $db->prepare("SELECT user_id FROM user_dates WHERE date_available = :date_available");
$find_query->bindParam(':date_available', $post_date);
$find_query->execute();
$result_find = $find_query->fetchAll(PDO::FETCH_ASSOC);
if(count($result_find) > 0) {
  foreach($result_find as $row) {
    $user_id =	$row['user_id'];
  }
  $delete_query = $db->prepare("DELETE FROM user_dates WHERE user_id = :user_id");
  $delete_query->bindParam(':user_id', $user_id);
  $delete_query->execute();
  $result_delete = $delete_query->execute();
  if($result_delete == false) {
   echo 'delete false';
  } else {
   echo 'delete success';
  }
} else {
  $insert_query = $db->prepare("INSERT INTO user_dates(date_available) VALUES(:date_available)");
  $insert_query->bindParam(':date_available', $post_date);
  $result_insert = $insert_query->execute();
  if($result_insert == false) {
   echo 'insert false';
  } else {
   echo 'insert success';
  }

}

 

The above code works fine. It inserts and deletes a date row in MySQL database table based on a click.

Now what I would like to do is to highlight all the "available" dates that are already inserted into the database; so that the user knows which dates he has already selected. This is my code for that. But it doesn't seem to be working. No errors. It's just not highlighting the inserted dates. Can you tell me what I'm doing wrong?

// JQUERY
<script>
    $(document).ready(function() {

        $.post('snippets/adapter-fetch.php', {}, function(data){
            $("#datetimepicker1").datepicker({
              datesEnabled : data.datesEnabled
            });
        }, 'json');

    });
</script>

// PHP
// adapter-fetch.php

$global_user_id = 5;

$find_query = $db->prepare("SELECT date_available FROM user_dates WHERE user_id = :user_id");
$find_query->bindParam(':user_id', $global_user_id);
$find_query->execute();
$result_find = $find_query->fetchAll(PDO::FETCH_ASSOC);
if(count($result_find) > 0) {
  foreach($result_find as $row) {
    $date_available =	$row['date_available'];

    echo $date_available;
  }
} else {
  echo 'not dates available';
}

 

I just have a general question about when other programmers remove rows older than say a year old....

Do most of you:
1) set up a CRON job to run daily at 3:00am
2) Add a routine at login for each user
3) Add a routine when a user moves into a certain portion of the application
4) A maintenance routine that an administrator manually has to envoke

Or is there another way...I have done some research but most of the things google has showed me is the how not when to do this...

Hi guys,

I am trying to do a multidates events availability calender. The script below indicates todays date by highlighting an orange colour and also indicates the start and end date of the event highlighting grey colour on the two dates (The colour are link via css classes as shown).
Code: [Select]
//Today's date
$todaysDate = date("d/m/Y");
            $dateToCompare = $daystring . '/' . $monthstring . '/' . $year;
echo "<td align='center' ";
if($todaysDate == $dateToCompare){
echo "class='today'";
}else{
//Compare's the event dates
$sqlcount = "select event_start,event_end from b_calender where event_start ='".$dateToCompare."' AND event_end='".$dateToCompare."'";
$noOfEvent = mysql_num_rows(mysql_query($sqlcount));
if($noOfEvent >= 1){
echo "class='event'";
}
}
It works ok i.e. if start date = 01/01/2012 and end date = 04/01/2012 both date will be highlighted with grey colour. However I want it to also highlight grey on the dates between the 1st and 4th to show that then anydates between the 1st and 4th are not available and this is when I'm stuck.

Please guys I need help.

Thanks

Hi,
So I only want my users to be able to perform certain tasks each 12 hours.
This is the code I use:
Code: [Select]
function canVote($ip, $vote_id, $updateTimer = true){
$time = date("Y-m-d H:i:s");

$this->CI->db->where('vote_id', $vote_id);
$this->CI->db->where('user_ip', $ip);
$this->CI->db->from('votes_voters');
$count =  $this->CI->db->count_all_results();
/*$count = $this->CI->db
->where('vote_id =', $vote_id)
->where('user_ip =', $ip)
->from('votes_voters')
-count_all_results();*/

$row = $this->CI->db
->where('vote_id =', $vote_id)
->where('user_ip =', $ip)
->get('votes_voters')
->row();

if($count == 0){
$data = array(
   'vote_id' => $vote_id,
   'user_ip' => $ip,
   'last_vote' => $time
);

$this->CI->db->insert('votes_voters', $data);
return true;
}
else{
$last_vote = $row->last_vote;
if($last_vote + strtotime("12 hours") < $time){
return false;
}
else{
if($updateTimer = true){
$data = array(
               'last_vote' => $time,
            );

$this->CI->db->where('vote_id', $vote_id);
$this->CI->db->where('user_ip', $ip);
$this->CI->db->update('votes_voters', $data);
}
return true;
}
}
}
Apparently the failing bit is this:
Code: [Select]
if($last_vote + strtotime("12 hours") < $time){
return false;
}
I believe you can guess what I'm trying to do here, if variable 1 + 12 hours is smaller than variable 2, then return false.
Any help is much appreciated.

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

Hey guys,

What I'm trying to do is set 2 dates.  Today's date and then a date 14 days from now.  However, I want it to increase the month if by adding 14 days will bring me to the next month, same with the year.

I have this, but it doesn't increment the month or year.

$week = mktime(11, 59, 59, date("m"), date("d")+14, date("y"));
$date =  date("Y-m-d H:i:s", $week);

Hey, I have just recently coded a forum and my topics are ordered by date. This means if there is a topic at 4pm and then there is another topic made at 4:01pm the topic which was posted at 4:01pm will be listed at the top.

I know how to add timezones but there is bit of a problem,  if  person from the UK posts a topic and his/hers timezone is set to:

date_default_timezone_set('Europe/London');()

this means the time at which the topic was posted will be 20:36pm (Just a randome time example).

However if someone posted a topic from america/los_angeles one hour before the one above his/her time will be 11:36 am. Even though this topic was posted one hour before the UK post. The UK topic will override it because it is 8:36pm. In fact, all UK topics will show up at the top and all the america/los_angeles topics will show bellow.

How do I slove this problem? I just don't get it even tough I looked online.

Please help, thanks.

i want to created a case like the following need help with the syntax:
Code: [Select]
switch (true)
{
case($fromdate-$todate==17-04-2001-25-04-2011):
echo $finalprice = $result;
        break;
}

I am trying to get data out of my database to display in a graph, the problem I have is that if there are no rows on a certain date then that date does not get placed into the array.

I am thinking I will need to loop through previous dates and match the 'current working date' to the keys of my array to see the total number of rows

my array of data from the database will look like this :-
Code: [Select]
Array
(
    [2011 April 25th] => 32
    [2011 April 26th] => 70
    [2011 May 6th] => 86
    [2011 May 7th] => 86
    [2011 May 8th] => 87
    [2011 May 9th] => 86
    [2011 May 10th] => 86
    [2011 May 11th] => 79
)
notice the gap between april 26th and may 6th, thats because there are 0 rows in the database that fall on these days.

Whats the best way to loop through say the past month?

Hope this makes sense, if there is a better method I would be glad to hear it.

I need to do some reporting and I need some help.  The reporting periods are as follows:

08/28-09/03
09/04-09/10
09/11-09/17
09/18-09/24
09/25-10/01

So, they are Sunday through Saturday throughout each month.  Say the date is Sept. 7.... How can I find out the date of the Sunday before last.  How can I know what month I am reporting for?

I am querying the database each Wed. for sales data from the previous month.  I want to take the totals from my query and store them in a separate table.  The problem is, I don't know how to find out what month the previous week falls into.  And I don't know how to find the date of the Sunday before last.

Thanks,

Jake

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

When just generating HTML, where should dates be formatted?  What about when generating JSON (I've found that date formatting is not so straight forward using JavaScript)?  Are there factors which may make one approach better than the other (i.e. querying one record versus a list of records)?  How important is consistency of an approach?  Any other factors I should consider?  Please provide rational for your decision.  Thank you     At the database?

DATE_FORMAT(my_date, "%m/%d/%Y %r") AS my_date

In the controller?

$date = new DateTime($my_date);
$my_date=$date->format('m/d/Y');

In a twig or smarty template?

{{ mydate|date("m/d/Y g:i A") }}

At the client using handlebars and the Moment library?

UI.registerHelper("formatDate", function(datetime, format) {
if (moment) {
f = DateFormats[format];
return moment(datetime).format(f);
}
else {
return datetime;
}
});

...

{{formatDate MyISOString "short"}}

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.
  Code: [Select]
<html><head>
<meta http-Equiv="Cache-Control" Content="no-cache">
<meta http-Equiv="Pragma" Content="no-cache">
<meta http-Equiv="Expires" Content="0">
<?
$proFile = "profilePics/profile.jpg";
//if ( date ("m d Y H:i:s.") - date ("m d Y H:i:s.", filemtime($proFile)) <= 00 00 0000 00:00:04 ){ //this is where the magic should happen.
//echo "<meta http-equiv="refresh" content='4'>"; }
?>

<?
echo date ("m d Y H:i:s.");
echo "<br>";
echo date ("m d Y H:i:s.", filemtime($proFile));
echo "<br>";
echo  date ("m d Y H:i:s.") - date ("m d Y H:i:s.", filemtime($proFile)); //only outputs 0
