PHP - Detect Your Time?

Ok, so I have a code that looks like so:
Code: [Select]
<script type="text/javascript">
    var ng_config = {
        assests_dir: 'ng/assets/' // the path to the assets directory
    }
</script>
<script type="text/javascript" src="ng/ng_all.js"></script>
<script type="text/javascript" src="ng/components/calendar.js"></script>
<script type="text/javascript">
var my_cal;
ng.ready(function(){
        // creating the calendar
       var my_cal = new ng.Calendar({
            input: 'enddate',
            start_date: 'year - 1',    // the start date (default is today)
            display_date: ng.get('startdate').value,  // the display date (default is start_date)
  server_date_format: 'm/d/Y'    // changing the server date format for a specific calendar.
        });
    });
var my_cal1;
ng.ready(function(){
        // creating the calendar
        my_cal1 = new ng.Calendar({
            input: 'startdate',
            start_date: 'year - 1',    // the start date (default is today)
            display_date: new Date(),   // the display date (default is start_date)
  server_date_format: 'm/d/Y'    // changing the server date format for a specific calendar.
        });
    });
how do I detect the months that pass between the two dates that are selected using a popup calendar using php so that my register page know which month to display the event under.  Does this make sense?

Hello.

Would php be the right thing to use in regards to monitoring changes in html on certain pages, Basicly, I'd need it to be something like:

"Page last changed: 2 Days, 4 Hours, 34 Minutes and 13 Seconds ago."

What would I use for this?

Thanks

I am having a problem with PHP displaying the correct date and time. It updates as it should, but is fast by 4min and is always displaying a date in 2004. I ran a basic php script to make sure the application im using itself is not wrong. go to lunenburgledger.com/time.php

Anybody had any ideas on where to check? The system time on the Windows Server 2003 is correct. The only thing I can think of is that it was converted to a virtual machine on vmware esxi, but the system time stayed right. Any ideas?

Thanks!

Hello,

I tried to implement some PHP code to enable a web page to show "Dinner" specials versus "Lunch" specials based on the time.

The business is located in the Eastern Time Zone, so I only need to routine to work based on Eastern Time (New York).

What I am noticing is that the server is processing the lines of code so fast that the command to establish the correct time for the remaining code is not always being acknowledged.

This line of code appears to be processing too fast for the remaining lines of code:
date_default_timezone_set ( "America/New_York" );

Is there some additional code I can put in place to make sure the correct time is always ascertained?

I need the $hourmin variable to always return a combination of hour + minute based on 24-hour time and Eastern Time zone.

My code is as follows:


 <?php
   $name8 = file_get_contents("test/special8name.txt");
date_default_timezone_set ( "America/New_York" );
$gethour = date("H");
$getminutes = $gettimedate["minutes"];
$gettimedate = date();
$hourmin = $gethour . $getminutes;
$currentday = date("l", time());
$currentdate = date("M j, Y");
if ($hourmin < 1500 && $currentday <> "Saturday" && $currentday <> "Sunday") {
   echo "<span class=\"namesred\">$name8 </span>";
}
  else if ( $hourmin > 1500 && $hourmin < 2300 && $currentday <> "Saturday" && $currentday <> "Sunday") {
   echo "<span class=\"namesblue\">$name8 </span>";
  }
  else if ( $currentday == "Saturday" or $currentday == "Sunday") {
   echo "<span class=\"namesblue\">$name8 </span>";
  }
?>

OK So I've got a datepicker that sends a date in d/m/y format. My DB stores the data in Unix Timestamp Which I can convert the date to with strtotime however this does the exact date & time.

All I want is the actual day. I've spent hours trying to convert this with just the day with mixed results...

Thanks.

PHP 5.2.6

We rent PHP server space on a server in California. Several of my pages generated by PHP show the current date and time, so when the page is printed, the user knows when the data was printed. Our users could be anywhere in the US, I am in Michigan. How do I convert the server time (PDT) into local time, regardless of where the user is?

Thanks.

Hi guys, I have this code:

<?php

// This Code Works

if (isset($_POST{"PantryID"})) {

Create_Pantry($_POST{"PantryID"});

}

// This Code Isn't Working, Keeps Going To 'Else'.

if (isset($_POST{"ItemName"})){

Add_Item($_POST{"ItemName"}, $_POST{"ItemWeight"}, $_POST{"ItemPrice"}, $_POST{"ItemDate"});

}else{

echo "Nothing To do";

}

?>

 

here is the html

<label for="PantryID">Create Pantry: </label>

<input type="text" id="PantryID" name="PantryID" disabled="true" />

<label for="ItemName">Item Name: </label>

<input type="text" id="ItemName" name="ItemName" disabled="true" />

Please help, I can't find any syntax errors.  - At the point the PHP is activated it is no longer disabled. the PantryID  is set up the same way.

Hi,
   how can i detect if my website is being open in mobile type all devices instead of computer
Please help

i'm trying to use this code to detect if the browser of the user is IE (any version) and id true (if it is IE), then it's redirected to an error page; otherwise, it's ok and sent ot the index. I get the following error...

Warning: Cannot modify header information - headers already sent by (output started at /index.php:1) in /xie.php on line 13

any ideas.. ???


<?php
function ae_detect_ie()
{
if (isset($_SERVER['HTTP_USER_AGENT']) && 
    (strpos($_SERVER['HTTP_USER_AGENT'], 'MSIE') !== false))
        return true;
    else
        return false;
}
if (ae_detect_ie()) {
header("Location: error.php");
} else {
header("Location: index.php");
}
?>

How can I detect if the page was refreshed?  I thought the following worked, however, after much head scratching, discovered it does not work for a POST request using the Chrome browser.  Thanks

<?php
$refresh=isset($_SERVER['HTTP_CACHE_CONTROL']) && $_SERVER['HTTP_CACHE_CONTROL'] === 'max-age=0';
echo(($refresh?'refresh':'not refresh').'<br>');
echo('$_GET<pre>'.print_r($_GET,1).'</pre>');
echo('$_POST<pre>'.print_r($_POST,1).'</pre>');
?>
<ul>
<li><a href="refresh.php?id=1">one</a></li>
<li><a href="refresh.php?id=2">two</a></li>
<li><a href="refresh.php?id=3">three</a></li>
</ul>
<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<input type="text" name="text" value="hello">
<input type="submit" name="submit" value="submit">
</form>

Why does the following code not detect the following file? After I select a file and I click upload, it goes back to the upload form.


<?php
include_once("includes/config.php");

//grab their type
if(!$_COOKIE['user'])
{

//they are a guest

$info = "Guest";
}
else
{

//they are a user

$info = $_COOKIE['user'];
}


if(!$_FILE['file'])
{

$content = '<form action="submit.php" method="post" enctype="multipart/form-data">
<label for="file">SELECT SKIN:</label>
<input type="file" name="file" id="file" />
<input type="submit" name="submit" value="Submit" />
</form>';
}
else
{

if($_FILES['file']['error'] > 0)

{

$content = "There was an error trying to upload the skin ".$_FILES['file']['name'].".".$_FILES['file']['error'];

}

}

?>
<html>
<head>
<title><?php $title; ?></title>
<link rel="stylesheet" type="text/css" href="theme/style.css" />

I have a problem, where i need to know when user leave or close tha browser tab. I tryd to make a ajax post, after unload, make a POST into kill_browser.php and after 1 minute when session_expire, php code will be execute and save time into database. But it not seems to work :/ I'm glad if some 1 can say what im doing wrong, or is there eny better way to detect it.   @home.php   var leaved = 'leaved';
$(window).unload(
        function(){
            $.ajax({
            url: 'kill_browser.php',
            global: false,
            type: 'POST',
            data: leaved,
            async: false,
            success: function() {
            console.log('leaved');
            }
        });
    });   @kill_browser.php <?php

require('class/connection.php');
$conn = new connection();
session_cache_limiter('private');
$cache_limiter = session_cache_limiter();
session_cache_expire(1);
$cache_expire = session_cache_expire();
session_start();
$_SESSION['leaved'] = $_POST['leaved'];
if($_SESSION['leaved'] == null || $_SESSION['leaved'] == " "){
    $conn->logOut($_SESSION['userID'], $_SESSION['userIP'], $_SESSION['LAST_GENERATED_ID']);
    session_regenerate_id(true);
    unset($_SESSION);
    session_destroy();
    header('location:index.php');
}
?>

In PHP?

Let's say I'm going off of:
width x height





So this is 2x1

2x1

2 blocks across, 1 block height.

How do I check this against other blocks in php to see if the 2x1 will overlap another set of dimensions dynamically?

Am I over thinking this?
