How can i get data from using date range for querying multiple details from a table?

Question

I\'ve been able to get multiple details from this table, using the codes beneath the table...

I know the table looks odd, but that\'s the available data table from the cl

Answer 1

I hope this will help

    <?php 
  

$Date1 = '01-10-2010'; 
$Date2 = '07-12-2010'; 
  

$array = array(); 
$range = 0;

$Variable1 = strtotime($Date1); 
$Variable2 = strtotime($Date2); 
  

for ($currentDate = $Variable1; $currentDate <= $Variable2;  
                                $currentDate += (86400)) { 
                                      
$Store = date('Y-m-d', $currentDate); 
$array[] = $Store;
$range++;

} 
for ($i=0; $i < $range; $i++) { 
    echo $array[$i];
}
  


?>

First, change your dates from

$datfrm ="00/00/0001";
$datto ="31/12/2099";

to

$datfrm ="00-00-0001";
$datto ="31-12-2099";

then add

    if (empty($last_score)) {
      $last_score=0;
    }else{

    }
    

between

$last_score = trim($scores[count($scores)-1]);

and

$finalScore15 += $place_map[$last_score];

that should solve your problem completely.

Answer 3

I was having a bit of trouble understanding exactly what you wanted out of e1 and e2 - assume its just the last value in the field. If I got that wrong, you can correct it in the function $eview.

Here is code that yields a result of 4.2 with the data you posted.

$datfrm = "";       // or something like '2010-01-01'
$datto = '2200';    // or something like '2015-12-01'

$gender="male";

$place_map = ['first' => 1, 'second' => 0.8, 'third' => 0.4];

// My understanding of the code is to get the weighted value of the
// last word in the column - if that's wrong, you can change this
// I am assuming you want the date that corresponded to the item you used
// for the final score, so if wrong, you need to change this.
// Also assume there will be the same number of dates as 'e's
//
// return false if bad value, or 0 if not in date range
$eview = function ($row, $ecol, $dcol) use ($place_map, $datfrm, $datto) {
    $parts = array_filter(array_map('trim', explode(",", $row[$ecol])));
    $dates = array_filter(array_map('trim', explode(",", $row[$dcol])));
    if (!$parts || count($parts) != count($dates)) {
        echo "Expected same number of parts and dates!\n";
        return false;
    }
    $date = array_pop($dates);      // Getting last date...
    return ($date >= $datfrm && $date < $datto) ?
           ($place_map[array_pop($parts)] ?? false) : 0;
    };

$finalScore1 = $finalScore2 = 0;

// perform the query ...
$query = "SELECT e1, e2, d1, d2 FROM eyfstb WHERE gender = '{$gender}'";
if ($result = $db->query($query)) {
        /* fetch associative array */
    while ($row = $result->fetch_assoc()) {
      $finalScore1 += $eview($row, 'e1', 'd1') ?: 0;
      $finalScore2 += $eview($row, 'e2', 'd2') ?: 0;
    }
}

echo ($finalScore1+$finalScore2) . "\n";

Answer 4

You want to skip lines where there are not exactly 3 elements in the e1 field. After the line: $efind = explode(',', $efind);, add this:

if (count($efind) !== 3) {
    continue;
}

Add this in both places.

Another problem in the code is that when you try to compare dates, you compare strings with <= and >=. You should instead use strcmp().

Without knowing the entire content of your table, it is hard to see where the undefined index error comes from.

Answer 5

You are doing

if ($result = $db->query($query)) {
    $finalScore1 = 0;
   ......
}

if ($result = $db->query($query)) {
   $finalScore2 = 0;
   .......
}


echo ($finalscore +$finalscore2);

Try to do:

$finalScore1 = 0;
if ($result = $db->query($query)) {
   ......
}

$finalScore2 = 0;
if ($result = $db->query($query)) {
   .......
}


echo ($finalscore +$finalscore2);

You have also not defined, define on the top of all:

$place_map = ['first' => 1, 'second' => 0.8, 'third' => 0.4];

Hope these resolve you error, rest result as per data and code
