I have mock fantasy football form that creates data in an external text file and I have everything working, I have just run into one problem. Can someone show me how I can sort the players by their number (largest on top) and then highlight (in red) the whole row of the player that has had the most points?
Here is my form file:
<!doctype html public "-//W3C//DTD HTML 4.0 //EN">
<html>
<head>
<title>Fantasy Football</title>
</head>
<body>
<form action="team.php" method="POST">
<table border="1">
<tr><td>Player Name</td><td><input type="text" name="name"</td></tr>
<tr><td>Position</td><td><input type="text" name="position"</td></tr>
<tr><td>Number</td><td><input type="text" name="number"</td></tr>
<tr><td>Team</td><td><input type="text" name="team"</td></tr>
<tr><td>Points per game</td><td><input type="text" name="points"</td></tr>
<tr><td colspan="2" align="center"><input type="submit"></td></tr>
</table>
</form>
</body>
</html>
And here is the return data:
<?php
$name = $_POST['name'];
$team = $_POST['team'];
$number = $_POST['number'];
$position = $_POST['position'];
$points = $_POST['points'];
$DOC_ROOT = $_SERVER['DOCUMENT_ROOT'];
@ $fp = fopen("$DOC_ROOT/../php/football.txt","ab");
if(!$fp) {
echo 'Error: Cannot open file.';
exit;
}
fwrite($fp, $name."|".$team."|".$number."|".$position."|".$points."
");
?>
<?php
$DOC_ROOT = $_SERVER['DOCUMENT_ROOT'];
$players = file("$DOC_ROOT/../php/football.txt");
echo "<table border='2'>";
echo "<tr> <td>Name</td> <td>Team</td> <td>number</td> <td>Position</td> <td>Points</td> </tr>";
for($i = 0; $i < sizeof($players); $i++) {
list($name,$team,$number,$position,$points) = explode('|', $players[$i]);
echo '<tr><td>'.$name.'</td><td>'.$team.'</td><td>'.$number.'</td>
<td>'.$position.'</td><td>'.$points.'</td></tr>';
}
echo '</table>';
?>
Not really good at inserting bits an pieces of code, so if you could, can you tell me exactly where to put whatever you can give me?
Update:
Is this where I needed to put everything? The way it is now, when I submit my form I don't see anything! Obviously I did something wrong, so I'm open to suggestions!
<?php
function sort_player_array( $array, $key, $asc = true) {
$result = array();
$values = array();
foreach ($array as $id => $value) {
$values[$id] = isset($value[$key]) ? $value[$key] : '';
}
if ($asc) {
asort($values);
}
else {
arsort($values);
}
foreach ($values as $key => $value) {
$result[$key] = $array[$key];
}
return $result;
}
?>
<?php
$name = $_POST['name'];
$team = $_POST['team'];
$number = $_POST['number'];
$position = $_POST['position'];
$points = $_POST['points'];
$DOC_ROOT = $_SERVER['DOCUMENT_ROOT'];
@ $fp = fopen("$DOC_ROOT/../php/football.txt","ab");
if(!$fp) {
echo 'Error: Cannot open file.';
exit;
}
?>
<?php
fwrite($fp, $name."|".$team."|".$number."|".$position."|".$points."
");
$players = file("$DOC_ROOT/../php/football.txt");
$player_array = array();
foreach($players AS $player)
{
list($name,$team,$number,$position,$points) = explode('|', $players[$i]);
$player_array[] = array('name' => $name,
'number' => $number,
'position' => $position,
'points' => $points,
);
}
$sorted_players = sort_player_array($player_array, 'number', true);
foreach( $sorted_players AS $player )
{
echo '<tr><td>'.$player[name].'</td><td>'.$player[team].'</td><td>'
.$player[number].'</td><td>'.$player[position].'</td><td>'.$player[points].'</td></tr>';
} ?>
