I'm trying to get this data to display from month to month in a database. Right now the data is called $month and there is also a date stored in the database by month and also complete date. This is the code that somebody was helping me with. I am very new to PHP. Right now it goes forwards and backwards but doesn't display the current month.

if (!isset($_REQUEST['next']) || !isset($_REQUEST['prev'])) {
	 	$month= ltrim(date('m'),0) ;
	 }
	 $direction = '';
	 if (isset($_REQUEST['next'])){ 
	    $direction = 'next';
	 }
	if (isset($_REQUEST['prev'])){ 
		$direction = 'prev';
	}
	if ($direction == 'next'){
	 	$month = $month + 1;
		print_r($month);
	 } else {
	 	$month = $month - 1;
		print_r($month);
	 }
 	 date_default_timezone_set('America/New_York');




<form method="post" action="/reports.php">
<input type="submit"/>
<input type="hidden" name="prev" val="next"/>
</form>


<form method="post" action="/reports.php">

<input type="submit"/>
<input type="hidden" name="next" val="next"/>
</form>

This article describes how to handle date/time values in PHP and MySQL.  Please read it over and post back if you still have questions about the concepts.

I don't see how you are keeping track of the current month with the code you supplied.  Unless it is handled in some code that you're not showing here your $month will always be the current month.

In line 1 of your code you are checking to see if Next OR Previous are Not selected.  This will always be True, so I think you want to check if Next AND (&&) Previous are Not selected.
if (!isset($_REQUEST['next']) && !isset($_REQUEST['prev'])) {

Also your "prev" hidden field has a value of "next" which I'm guessing should be a value of "prev".

See if this helps.  I may be misunderstanding the question, but as I interpret it the question would be "How do I get the values for the previous or next month?"  If that's not what you want, please give us a little more to go on.

<?php // demo/temp_designaire.php
error_reporting(E_ALL);

date_default_timezone_set('America/New_York');

$get = !empty($_GET['q']) ? trim(strtolower(substr($_GET['q'],0,1))) : FALSE;
if ($get)
{
    // TO FIND NEXT MONTH
    if ($get == 'n')
    {
        $next = mktime( 0,0,0, date('m') + 1, date('d'), date('Y') );

Thanks, I got somebody to help me with it...It doesn't go through the years but it will work for what I need it for...

I'll try to look at your code and use it on a later date


$month = (int) (isset($_GET['month']) ? $_GET['month'] : date('m'));

if ($month=="")
{  
	date_default_timezone_set('America/New_York');
	$dateTime = date(DATE_RSS);      
	echo $dateTime . "<br>" . "<br>";
	echo "date('m') =" . date('m') . "<br>" . "<br>";  	 
	$month = ltrim(date('m'),0) ;  	
	echo "ltrim(date('m'),0) =" . $month . "<br>" . "<br>";  // I think that all 
}

$prevmonthtopost = ((($month+11)-1) % 12) + 1;  
$nextmonthtopost = ((($month+11)+1) % 12) + 1;  
?>

<form method="post" action="/next3.php?month=<?php echo $prevmonthtopost ?>">
  <input type="submit" value="previous" name="prev"/>
</form>
<p></p>
<form method="post" action="/next3.php?month=<?php echo $nextmonthtopost ?>">
  <input type="submit" value="nextious month" name="next"/>
</form>

<h1>Month <?php echo $month ?></h1>

<!-- Or you could do it this way -->
    <h1>Days in <?php echo $month ?> you meditated.</h1></div>
