Display records in Months and Days table

[marky7890]

Hello,

I am trying to display rainfall totals for the year so far in a table with months going across and days going down. Like so:

 

-- Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec

1

2

3

4

5

6

7

8

etc

 

And then have the rainfall totals for each day in the table, I am quite experienced with PHP however I cant work out how I would do this 

 

The data is stored in a mysql table called "wx_daily", and the rainfall column is called" RainTotal". The dates are stored in the "Date" column in mysql Date format.

 

Im using the following mysql query:

 

SELECT * FROM wx_daily WHERE YEAR(Date) = '2011' ORDER BY Date Asc

 

 

Thanks,

Mark

Can you tell me the table structure.

Here it is:

 

  `Date` date NOT NULL,

  `TempMin` decimal(5,1) NOT NULL,

  `TempMinTime` time NOT NULL,

  `TempMax` decimal(5,1) NOT NULL,

  `TempMaxTime` time NOT NULL,

  `DewPtMin` decimal(5,1) NOT NULL,

  `DewPtMinTime` time NOT NULL,

  `DewPtMax` decimal(5,1) NOT NULL,

  `DewPtMaxTime` time NOT NULL,

  `HumMin` decimal(5,1) NOT NULL,

  `HumMinTime` time NOT NULL,

  `HumMax` decimal(5,1) NOT NULL,

  `HumMaxTime` time NOT NULL,

  `WdChill` decimal(5,1) NOT NULL,

  `WdChillTime` time NOT NULL,

  `PressureMin` decimal(5,1) NOT NULL,

  `PressureMinTime` time NOT NULL,

  `PressureMax` decimal(5,1) NOT NULL,

  `PressureMaxTime` time NOT NULL,

  `WindGust` decimal(5,1) NOT NULL,

  `WindGustDir` decimal(5,1) NOT NULL,

  `WindGustTime` time NOT NULL,

  `WindSpeed` decimal(5,1) NOT NULL,

  `WindSpeedDir` decimal(5,1) NOT NULL,

  `WindSpeedTime` time NOT NULL,

  `Windrun` decimal(5,1) NOT NULL,

  `RainRate` decimal(5,1) NOT NULL,

  `RainRateTime` time NOT NULL,

  `RainTotal` decimal(5,1) NOT NULL,

  `SnowTotal` decimal(5,1) NOT NULL,

  `WindDomDir` varchar(11) NOT NULL,

  UNIQUE KEY `Date` (`Date`),

I can't think of any way to arrange your data to do this inside the while loop that pulls the database values.  But, you can store that data to sort it later.  My idea is along the lines of:

UN-TESTED

<?php 

$sql = "SELECT RainTotal, MONTH(`Date`) as `month`, DAY(`Date`) as `day` FROM wx_daily WHERE YEAR(Date) = '2011' ORDER BY Date Asc";
$result = mysql_query($sql) or trigger_error(mysql_error());
if(mysql_num_rows($result) == 0) {
echo 'No data exists!';
exit();
}

while($r = mysql_fetch_assoc($result)) {
$storage[$r['day']][$r['month']] = $r['RainTotal'];
}
echo '<table><tr><th>Day</th><th>Jan</th><th>Feb</th><th>Mar</th><th>April</th><th>May</th><th>June</th><th>July</th><th>Aug</th><th>Sep</th><th>Oct</th><th>Nov</th><th>Dec</th></tr>';

foreach($storage as $day => $monthArray) {
echo '<tr><td>' . $day . '</td>';
for($i = 1; $i < 13; $i++) {
	if(array_key_exists($i,$monthArray)) {
		echo '<td>' . $monthArray[$i] . '</td>';
	}
	else {
		echo '<td>0</td>';
	}
}
echo '</tr>';
}
echo '</table>';

?>

jcbones' solution is great with the following possible hiccup. It assumes you have information for every day of the month in at least one of your months. If, somehow, for some reason, you didn't have data for the 23rd day of every month in a given year, the script would skip that day.

 

It will probably never happen like that, but I figure I'd point it out for educational sake. A solution would be to pre-populate the storage array like this:

 

for( $i=0; $i<=31; $i++ ) $storage[$i] = array();

Thanks everyone for your help, jcbones your solution worked great.

Very true, and something that can be implemented easily.  Although, I would use:

$storage = array_fill(1,31,array());

That would be the simpler code Never really used array_fill(), always range(). Good to know.
