Need help with QueryString ..

spacepoet · April 22, 2011

Hi:

How can I build a querystring (or whatever I need to do to solve my issue) to pull in the month and year?

Meaning:

I have this link:

Entertainment.php

which goes to a dynamic calendar, which works fine except it does not show the events because I think it replies

on getting the current month and year.

When I click on a "Next Month" and the click back to the current month, the URL is:

Entertainment.php?month=4&year=2011

and the events then display properly in the calendar.

How do I properly build a URL for this?

The calendar code looks like this:

<?php
ob_start();
$today = date("M Y");
?>

...

<head>
<script>
function show_evt(m,y,day){  
    location.href = "<?=$_SERVER['PHP_SELF'];?>?month=" + m + "&year=" + y + "&day=" + day;
}

function goLastMonth(month, year)
{

if(month == 1)
{
--year;
month = 13;
}

document.location.href =  '<?=basename($_SERVER['PHP_SELF']);?>?month='+(month-1)+'&year='+year;
} 
function goNextMonth(month, year)
{

if(month == 12)
{
++year;
month = 0;
}

document.location.href = '<?=basename($_SERVER['PHP_SELF']);?>?month='+(month+1)+'&year='+year;
} 
</script>
</head>

...

<p>

<?php 

$date =time ();

$day = (isset($_GET['day'])) ? $_GET['day'] : date('d', $date);
$month = (isset($_GET['month'])) ? $_GET['month'] : date('m', $date);
$year = (isset($_GET['year'])) ? $_GET['year'] : date('Y', $date);

$first_day = mktime(0,0,0,$month, 1, $year);

$title = date('F', $first_day); 

$day_of_week = date('D', $first_day);

switch($day_of_week){ 
     case "Sun": $blank = 0; break; 
     case "Mon": $blank = 1; break; 
     case "Tue": $blank = 2; break; 
     case "Wed": $blank = 3; break; 
     case "Thu": $blank = 4; break; 
     case "Fri": $blank = 5; break; 
     case "Sat": $blank = 6; break; 
}


$days_in_month = cal_days_in_month(0, $month, $year); 

?>
<table class="tableClass">
<tr class="field-bg-color">
     <th class="eventLeftArrow"><a href="javascript: void(0);" onClick="goLastMonth(<?php echo $month . ", " . $year; ?>)"><<<</a></th>
     <th colspan="5" class="eventHeader"><?=$title. " " . $year;?></th>
    <th class="eventRightArrow"><a href="javascript: void(0);" onClick="goNextMonth(<?php echo $month . ", " . $year; ?>)">>>></a></th>
</tr>
<tr class="calDates">
     <td>S</td>
     <td>M</td>
     <td>T</td>
     <td>W</td>
     <td>T</td>
     <td>F</td>
     <td class="lastOne">S</td>
</tr>
<?php

$day_count = 1;

?>
<tr>
<?php
while ( $blank > 0 ) { 
?>
<td>      </td>
<?php 
     $blank = $blank-1; 
     $day_count++;
} 

$day_num = 1;

while ( $day_num <= $days_in_month ) { 
    $sql = "select count(calName) as evt_count from calTbl where calDate ='" . $month . '/' . $day_num . '/' . $year . "'";
    $result = mysql_query($sql);
    while($row = mysql_fetch_array($result)){
        if($row['evt_count'] >= 1){
    ?>
            <td align="center" style="cursor:hand;cursor:pointer;background-color:#FF6A6A;text-align:center;" onclick="show_evt('<?=$month;?>','<?=$year;?>','<?=$day_num;?>');">
            <div class="brown-bg-color cal-head-text white-text bold-text"><?=$day_num;?></div>      
            
    <?php

        $result = mysql_query($sql);

                ?>
                <a href="<?=$_SERVER['PHP_SELF'];?>?month=<?=$month;?>&year=<?=$year;?>&day=<?=$day_num;?>"><?=$row['calName'];?></a></br>
            <?
            }
        }else{

            <td>
            <div class="brown-bg-color cal-head-text"><?=$day_num;?></div>      
    <?php
        }
    }
?>
    </td>
<?php 
$day_num++; 
$day_count++;

if ($day_count > 7){
?>
</tr><tr>
<?php
$day_count = 1;
}
} 

while ( $day_count >1 && $day_count <=7 ) { 
?>
<td> </td> 
<?php
$day_count++; 
} 
?>
</tr></table> 
<?php

if(isset($_GET['day'])){
         $sql = "select * from calTbl where calDate ='" . $month . '/' . $_GET['day'] . '/' . $year . "'";
         $result = mysql_query($sql);
         echo '<table class="data-table-class">';
         echo '<th>Event Name</th><th>Event Desc</th>';
        while($row = mysql_fetch_array($result)){
            echo '<tr><td>'. $row['calName'] . '</td><td>' . $row['calDesc'] . '</td></tr>';
        }
        echo '</table>';
}
?>
      
<div class="myClear"></div>

<?php
    ob_flush();
?>



</p>

Can anyone help me out? This is the last part and I am good to go!

Thanks!

So you want to get te values of month and day from the URL?

Hi:

What I need to have happen is when the link is clicked:

Entertainment.php

It goes to that page with the final URL looking like:

Entertainment.php?month=4&year=2011

Where the URL will always write the current month and year.

Does this make sense?

Thanks!

well $month=date("m"); will give you the month and $year=date("Y"); will give you the current year Im not sure you need to use $_GET for that

fugix · April 22, 2011

if you do what gevesen said....next you will set the link href to

Entertainment.php?month=$month&year=$year

Got it!

Entertainment.php?month=".date('n')."&year=".date('Y')."\"

Thanks for the pointers - helped me to work through it.
