here is the php codes and mysql query that i want to put into a table:

<form action="" method="post" class="niceform">
<fieldset>
    <legend>Job Orders</legend>\
    <table>
<tr>
<th>SSA</th>
<th>Months</th>
</tr>

         <?php

$datefrom= $_POST['timestamp'];
$dateto=$_POST['timestamp1'];

$parsemonth="";
$parseday ="01";

$conditionmonth=$parsemonth-3;


//january
if ($conditionmonth == '1'){

$sql="SELECT
a.specialist_partner_ID
,count(CASE WHEN a.receivedDate between DATE_SUB('2011-01-01', INTERVAL 3 MONTH) and         DATE_SUB('2011-09-30', INTERVAL 3 MONTH) THEN a.job_order_number ELSE null END) As December,
count(CASE WHEN a.receivedDate between DATE_SUB('2011-01-01', INTERVAL 2 MONTH) and  DATE_SUB('2011-09-30', INTERVAL 2 MONTH) THEN a.job_order_number ELSE null END) As November
,count(CASE WHEN a.receivedDate between DATE_SUB('2011-01-01', INTERVAL 1 MONTH) and   DATE_SUB('2011-09-30', INTERVAL 1 MONTH) THEN a.job_order_number ELSE null END) As October 
,count(CASE WHEN a.receivedDate between '2011-01-01' and  '2011-01-30'THEN a.job_order_number ELSE null END) As Jauary
,count(job_order_number) As Total
FROM jo_partner a
WHERE a.receivedDate BETWEEN '2011-01-01' AND '2011-12-31'
GROUP BY a.specialist_partner_ID";
}

//february
else if ($conditionmonth == '2'){

$sql="SELECT
a.specialist_partner_ID
,count(CASE WHEN a.receivedDate between DATE_SUB('2011-02-01', INTERVAL 11 MONTH) and    DATE_SUB('2011-02-29', INTERVAL 3 MONTH) THEN a.job_order_number ELSE null END) As November
,count(CASE WHEN a.receivedDate between DATE_SUB('2011-02-01', INTERVAL 10 MONTH) and  DATE_SUB('2011-02-29', INTERVAL 2 MONTH) THEN a.job_order_number ELSE null END) As December

,count(CASE WHEN a.receivedDate between '2011-02-01' and  '2011-02-29'THEN a.job_order_number ELSE null END) As February
,count(job_order_number) As Total
FROM jo_partner a
WHERE a.receivedDate BETWEEN '2011-01-01' AND '2011-12-31'
GROUP BY a.specialist_partner_ID";
}

//march
else if ($conditionmonth == '3')
{

$sql="SELECT
a.specialist_partner_ID
,count(CASE WHEN a.receivedDate between DATE_SUB('2011-03-01', INTERVAL 3 MONTH) and       DATE_SUB('2011-03-31', INTERVAL 3 MONTH) THEN a.job_order_number ELSE null END) As December
,count(CASE WHEN a.receivedDate between DATE_SUB('2011-03-01', INTERVAL 2 MONTH) and  DATE_SUB('2011-03-31', INTERVAL 2 MONTH) THEN a.job_order_number ELSE null END) As Jauary

FROM jo_partner a
WHERE a.receivedDate BETWEEN '2011-01-01' AND '2011-12-31'
GROUP BY a.specialist_partner_ID";
}

and so on and so forth… up to DECEMBER

while ($row = mysql_fetch_row($sql)
{

} 
?>
  </tr></table>
</fieldset>

the condition is when I select a month to view the report for that month, ex January, only data from January will only be visible and the last 3 consrctive month, ex december and november

Answer 1

Given that a table is build up using this kind of data:

<tr>
  <td>item1</td>
  <td>item2</td>
</tr>

It’s really simple to build the table using SQL, just bracket the data using the table tags:

SQL only code, not recommended because it leaves open a XSS security hole!
Only use this if you are 100% sure the data inside your DB is safe

/*escape all data coming from a user */
/*or even better just escape all incoming data *period* */
$SSAID = mysql_real_escape_string($_SESSION['SESS_SSA_ID']);

/*don't use 2 queries if you can do it in one */  
$result = mysql_query("SELECT CONCAT('<tr>',GROUP_CONCAT(
                              CONCAT('<td>',ug.group_name,</td>), SEPARATOR ' ')
                              ,'</tr>') as tablestring 
                      FROM user_group ug
                      INNER JOIN user u ON (ug.usr_group_ID = u.user_group_id)
                      WHERE u.SSA_ID = ''$SSAID' )";

$row = mysql_fetch_row($result);
echo "here comes the table";
echo $row['tablestring'];

This code constructs the whole table in SQL. An other option is to loop though the values and piece together the table in a while loop:

Code example using a while loop, escapes the output, preventing XSS

$result = mysql_query("SELECT ug.group_name 
                      FROM user_group ug
                      INNER JOIN user u ON (ug.usr_group_ID = u.user_group_id)
                      WHERE u.SSA_ID = ''$SSAID' )";
$table = "<tr>";
while ($row = mysql_fetch_row($result));
{
  $table .= "<td>".htmlspecialchars($row['group_name'], ENT_QUOTES, 'UTF-8')."</td>";
}
$table .= "</tr>";
echo "here comes the table";
echo $table;

Points to remember

• Use mysql_real_escape_string() on all $vars you inject into a SQL-statement.
• Always escape data you echo onto the screen using htmlspecialchars() to prevent XSS.
• Get out of the select * habit, only select what you need.
• Don’t use two queries and use php as a courier between them, use one query instead, see a tutorial on SQL joins.
