Question

I’m trying the code below to enter events into MySQL table using PHP. When I run it, it gives no error and no row is inserted into MySQL table. Where am I going wrong in the code?

Also when I change

$date = strtotime("third friday of $month[$j] $year[$i]");

to

$date = mktime(0,0,0,$month[$j],$k,$year[$i]);

it works for all days, but I’m looking for only third friday of every month..

<?php 
if(isset($_POST['myform'])){

         $day   =   array('1','2','3','4','5','6','7','8','9','10','11','12','13','14','15','16','17','18','19','20','21','22','23','24','25','26','27','28','29','30','31');
         $month =   array('1','2','3','4','5','6','7','8','9','10','11','12');              
         $year  =   array('2011', '2012','2013', '2014', '2015', '2016');   

         $startday   = $_POST['day'];
         $eventplace = $_POST['eventplace'];
         $eventname  = $_POST['eventname'];
         $eventtime  = $_POST['eventtime'];

        for($i=0; $i<count($year); $i++){

            for($j=0; $j<count($month); $j++){

                for($k=$startday; $k<count($day); $k = $k + 7){

                        $date = strtotime("third friday of $month[$j] $year[$i]");

                        $week = date('W', $date) ;

  $query = mysql_query(" INSERT INTO caldemo(day, month, year, eventname, eventtime, eventplace, eventweek)
                         VALUES ('".$k."', '".$month[$j]."', '".$year[$i]."', '".$eventname."', '".$eventtime."', '".$eventplace."', '".$week."' )")or die(mysql_error()) ;
              }
            }
         } 
      }
?>   


<form name="theform" method="post" action="caldemo.php">
<table>
<tr>
<tr>
<td>Event Venue:</td>
<td><input type="text" name="eventplace" size="50"></td>

<tr>
<td>Event Name:</td>

Try

for($j=0; $j<count($month); $j++){

  $date = strtotime("+2 week friday $month[$j] $year[$i]");
  $week = date('W', $date) ;
  $k = date('d', $date) ;

  $query = mysql_query(" INSERT INTO caldemo 
    (day, month, year, eventname, eventtime, eventplace, eventweek)
    VALUES 
    ('".$k."', '".$month[$j]."', '".$year[$i]."', '".$eventname."', 
    '".$eventtime."', '".$eventplace."', '".$week."' )")
  or die(mysql_error()) ;
}

Removed the third for loop. Changed the argument to strtotime and used day returned by it as $k in the query.
