PHP - Category And Datetime Field.

Hello All, I have the following code:

Code: [Select]
echo "<table width='615px' cellpadding='3' cellspacing='4' align='center'>";
echo "<tr>";
echo "<td align='left' width='150px'>";
echo  substr($row['date'],0,11); 
echo "</td>";
echo "<td align='left' width='465px'>";
echo $row["food"] ;
echo "</td>";
echo "</tr>";
echo "</table>";
And this outputs:

Apr 4 2011    Chicken Ceasar Salad, Garlic Toast, Cloddhoppers, Applesauce, & Milk

(etc.)

How can I add "Mon" in front of "Apr 4 2011"?

thanks!

Basically I am using DATETIME to store the time in which a row was input.
Format - 2010-11-13 21:31:53
How would I get the current time of page load and compare it to the database row "2010-11-13 21:31:53" then output the difference.

Example
$sqlresult = 2010-11-13 21:31:53;
$currentTime = (GET CURRENT DATE+TIME = (2010-11-13 21:31:55) );

Output -
This was posted 2 minute's ago.

Thank you in advance. Any help would be greatly appreciated.

I'm given something like this:
Sun Nov 06 2011 09:30:00 GMT-0500 (EST)

And i'm trying to turn that into
2011-11-06 09:30:00

I started by using explode and trying to loop through the day and month to figure it out, but that seems inefficient and overly complicated. Am i missing something?

Thanks

Hello!! i want to save datetimes into a mysql database. Their format is dd-mm-yy  hh:mm. I think mysql format for datetime is yy-mm-dd hh:mm..How can i convert them??

Hey, does anybody know a good function, where I can have the trendy "time ago" functionality?   A good tutorial would be cool, too.   I would be using the datetime function off MySQL.

Hi Everyone,

Please have a look at this, and tell me if its right?
I am generating a sitemap for my website dynamically.

The date I am providing: 2012-02-24 11:56:09 and this is the output I am getting: 2012-02-24T11:56:09Z
now I am not sure of the Z at the end of the returned value.

I think I am looking for something similar to this: 2012-03-12T12:00:02+02:00

not to sure what I am doing wrong and where it gets the timezone from, I am guessing from the php config file.

any help would be much appreciated. thanks

My code:

Code: [Select]
<lastmod><?php echo $time->toAtom($post['Post']['modified']); ?></lastmod>

Code: [Select]
OFXAdapter: Failed to parse request: Unable to parse an atomic field "OFXRequest.OFXRequest.SignOnMsgsRqUn.SignOnMsgsRqV1.SonRq.DtClient": field value "20101005091544.000[-4:EDT]" is not a valid (YYYYMMDDHHMMSS.XXX[gmt offset:tz name]) date.
I am trying to put together some PHP code to use the OFX standard to communicate with my bank in order to download my recent transactions. The standard details that in the sign-on request, the date and time must be included in the format listed above.

As you can see, I have the value in the exact same format as specified. So my question is this: is there something about GMT offset or TZ names that I am missing here?

Hi, I'm a newbie here, and with PHP, and need some help with the datetime display.
I am wanting to utilize old Naval comms DTG (datetimegroup) format which is DDHHMM 3-digit Month 2-digit year.
The DDHHMM = Day (01 - 31) HH (hour 01 - 24) MM (minute 00 - 59)
What I need to do is to add the letter Z (meaning GMT, ZULU) like thus  DDHHMMZ FEB 11
How can I go about inserting that Z into this?

Tks in advance for any assist

Hello,

I have a query that displays a list of events for the year, and am in need of guidance on how to have it only show events that are >= today's date. 

The 'date' is inserted into the table as a varchar field from javascript code.  There was an old blog post about doing something like....

Code: [Select]
SELECT * FROM calendar WHERE `date` >= NOW() ORDER BY date ASC LIMIT 5

I seem to have trouble in that i believe NOW() will only work with proper datetime entries as opposed to my varchar setup.

any help navigating this would be great.

Hi, so I am trying to get how many minutes and seconds are left from the datetime entry in the database and the current datetime, but I'm having issues...

Here's my code:
Code: [Select]
$query = "SELECT RequestMadeDateTime FROM TempAwaitingClients WHERE PSOID = '2'";
$result = mysql_query($query);
$row = mysql_fetch_assoc($result);
$RequestMadeDateTime = $row['RequestMadeDateTime'];
$currentDateTime = date('Y-m-d H:i:s');
echo 'Request Made Date Time: ' . $RequestMadeDateTime . '<br />';
echo 'Current Date Time: ' . $currentDateTime . '<br />';
echo date_diff($RequestMadeDateTime, $currentDateTime);

What I'm getting those is this, "Warning: date_diff() expects parameter 1 to be DateTime" ... Which I don't get because both variables are DateTime...

Hi all,
I have a loop that is modifying a DateTime object. It goes through X number of times and adds 1 day to the date time object and stores the modified object in an array. I use ->add(new DateInterval('P1D')); For some reason it is losing an hour each time that I add a day. I start out at 19:00 and each iteration through the loop adds a day, but loses an hour.
2010-09-19 19:00:00
2010-09-20 18:00:00
2010-09-21 17:00:00

I can correct for this by doing ->add(new DateInterval('P1DT1H'));, but adding 25 hours instead of 24 hours doesn't make any sense to me. I am using PHP Version 5.3.1.

Any ideas?

Thanks,
W

I have a function that receives two datetime values attached to the variables $start and $end.  These will be in the format 'Y-m-d H:i:s'.

For each of these values, I create a DateTime object to make the handling of them easier:
Code: [Select]
$startDT = DateTime::createFromFormat('Y-m-d H:i:s', $start);
$endDT = DateTime::createFromFormat('Y-m-d H:i:s', $end);

What I need to do now is ensure that the seconds of the $startDT value are always set to '00' and the seconds of the $endDT value are always set to '59'.

Is there an easy way to do this without having to extract the individual values for hours, minutes and seconds before reapplying them using the setTime function, adjusting the values accordingly?

I have a page where "Events" which may be of interest to site visitors can be recorded.

Among other info, an "Event" has a "from" date and a "to" date (to show that an event will run from October 29th to October 31st, for example).

All event info is being written to the db, but the "from" and "to" dates are not. (In the db, "0000-00-00 00:00:00" is being entered in the "from" and "to" columns.)

In the Events table, both event_date and event_end_date are of type datetime. Dates are entered into the form fields via a javascript datepicker and are in the format "24/09/2011".

I'm using this code:
Code: [Select]
// Check for a Start Date:
if (empty($_POST['from'])) {
$errors[] = 'You forgot to enter a Start Date for the event.';
} else {
$from = $_POST['from'];
}

// Check for an End Date:
if (empty($_POST['to'])) {
$errors[] = 'You forgot to enter an End Date for the event.';
} else {
$to = $_POST['to'];
}

The db query is this:
Code: [Select]
if (empty($errors)) { // If everything's OK.
// Insert the Event info in the database...
// Make the query:
$q = "INSERT INTO
events (title, event_date, event_end_date, venue, ext_link, blurb)
VALUES ('$title', '$from', '$to', '$venue', '$ext_link', '$blurb')
";
$r = @mysqli_query ($dbc, $q); // Run the query.
if ($r) { // If it ran OK.
// Print a message:
echo "<h2>Event info added!</h2>
<h3>Your entry is now visible on the <a href='index.php'>Home Page</a>.</h3>
<p><a href='logout.php'><strong>Log out</strong></a></p>
"
;
mysqli_close($dbc);
include('inc/footer.php');
exit();

And the form is this:
Code: [Select]
<form id="form1" name="form1" method="post" action="add_event.php">
<label for="title">Title</label>
<input type="text" name="title" id="title" value="<?php if (isset($_POST['title'])) echo $_POST['title']; ?>" />
<script>
$(function() {
var dates = $( "#from, #to" ).datepicker({
defaultDate: "",
changeMonth: true,
numberOfMonths: 1,
onSelect: function( selectedDate ) {
var option = this.id == "from" ? "minDate" : "maxDate",
instance = $( this ).data( "datepicker" ),
date = $.datepicker.parseDate(
instance.settings.dateFormat ||
$.datepicker._defaults.dateFormat,
selectedDate, instance.settings );
dates.not( this ).datepicker( "option", option, date );
}
});
});
</script>
<label for="from" >*From</label>
<input type="text" name="from" id="from" value="<?php if (isset($_POST['from'])) echo $_POST['from']; ?>" />

<label for="to" ">*To</label>
<input type="text" name="to" id="to" value="<?php if (isset($_POST['to'])) echo $_POST['to']; ?>" />
 
<label for="venue">*Venue</label>
<input type="text" name="venue" id="venue" value="<?php if (isset($_POST['venue'])) echo $_POST['venue']; ?>" />
 
<label for="blurb">*Description</label>
<textarea name="blurb" id="blurb" value="<?php if (isset($_POST['blurb'])) echo $_POST['blurb']; ?>" rows="5" ></textarea>
 
<label for="ext_link">External link (optional, entered like &quot;www.example.com&quot;)</label>
<input type="text" name="ext_link" id="ext_link" value="<?php if (isset($_POST['ext_link'])) echo $_POST['ext_link']; ?>" />
 
<input type="submit" name="submit" value="Insert Event Info" class="submit" /></p>
<input type="hidden" name="submitted" value="TRUE" />
</form>

Can anyone tell me why the dates aren't being recorded? Any help will be greatly appreciated.

I have multiple datetimes. The format is dd-mm-yy, hh:mm. I want to insert it into a table using mysql. However mysql format is yy-mm-dd, hh:mm:ss. How can i do it and what type should i use (datetime?timestamp?).
Thanks for your help!!

I'm having trouble inserting a formatted PHP DateTime into a MySQL table.

I'm getting:
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ',2012-01-31)' at line 4

I get the error when I try to insert the date as a string from a DateTime object via:
$insertDate = $date->format('Y-m-d');

As well as when I try to recast it as a date object:
$insertDate = date("Y-m-d",strtotime($date->format('Y-m-d')));

I've also tried putting the date in ' ' 's and escaped " " 's.


My insert query is:
$insert = "INSERT INTO pendingordersdetails (PartNumber,Oqty,Pqty,Aqty,PartStatus,
PartPrice,idOrderNo,PrtTariffCode,PrtLocation,LineNum,PKqty,SPqty,AllocationDate)
VALUES ('$partNum',$oQty,0,$aQty,'Excess',$price,$orderNum,'$tariffCode',
'$location',$lineNum,$PKqty,$SPqty,'$allocDate');";

and the echoed output is:
INSERT INTO pendingordersdetails (PartNumber,Oqty,Pqty,Aqty,PartStatus, PartPrice,idOrderNo,PrtTariffCode,PrtLocation,LineNum,PKqty,SPqty,AllocationDate) VALUES ('0446535240 ',3,0,1,'Excess',163.89,66,' ', 'A0406E01',2,,,'2012-01-31');

Anyone have any ideas?
