Cia a tutti sono nuovo del forum e nn sono molto pratico in php.
Sto facendo un sito sul fantacalcio, e ho travato un programma php su internet:
function main() {
?>
<style>
input, textarea { display: block; margin-bottom: 1em; }
label { font-weight: bold; display: block; }
</style>
<?php
// Find out how many teams we want fixtures for.
if (! isset($_GET['teams']) && ! isset($_GET['names'])) {
print get_form();
} else {
# XXX check for int
print show_fixtures(isset($_GET['teams']) ? nums(intval($_GET['teams'])) : explode("\n", trim($_GET['names'])));
}
}
function nums($n) {
$ns = array();
for ($i = 1; $i <= $n; $i++) {
$ns[] = $i;
}
return $ns;
}
function show_fixtures($names) {
$teams = sizeof($names);
print "
Calendario per $teams squadre.</p>";
// If odd number of teams add a "ghost".
$ghost = false;
if ($teams % 2 == 1) {
$teams++;
$ghost = true;
}
// Generate the fixtures using the cyclic algorithm.
$totalRounds = $teams - 1;
$matchesPerRound = $teams / 2;
$rounds = array();
for ($i = 0; $i < $totalRounds; $i++) {
$rounds[$i] = array();
}
for ($round = 0; $round < $totalRounds; $round++) {
for ($match = 0; $match < $matchesPerRound; $match++) {
$home = ($round + $match) % ($teams - 1);
$away = ($teams - 1 - $match + $round) % ($teams - 1);
// Last team stays in the same place while the others
// rotate around it.
if ($match == 0) {
$away = $teams - 1;
}
$rounds[$round][$match] = team_name($home + 1, $names)
. " v " . team_name($away + 1, $names);
}
}
// Interleave so that home and away games are fairly evenly dispersed.
$interleaved = array();
for ($i = 0; $i < $totalRounds; $i++) {
$interleaved[$i] = array();
}
$evn = 0;
$odd = ($teams / 2);
for ($i = 0; $i < sizeof($rounds); $i++) {
if ($i % 2 == 0) {
$interleaved[$i] = $rounds[$evn++];
} else {
$interleaved[$i] = $rounds[$odd++];
}
}
$rounds = $interleaved;
// Last team can't be away for every game so flip them
// to home on odd rounds.
for ($round = 0; $round < sizeof($rounds); $round++) {
if ($round % 2 == 1) {
$rounds[$round][0] = flip($rounds[$round][0]);
}
}
// Display the fixtures
for ($i = 0; $i < sizeof($rounds); $i++) {
print "
Giornata " . ($i + 1) . "</p>\n";
foreach ($rounds[$i] as $r) {
print $r . "
";
}
print "
";
}
print "
Il calendario si ripete a seconda del numero di giornate</p>";
$round_counter = sizeof($rounds) + 1;
print "
";
if ($ghost) {
print "La squadra " . $teams . " è un 'fantasma'.";
}
}
function flip($match) {
$components =explode(' v ', $match);
return $components[1] . " v " . $components[0];
}
function team_name($num, $names) {
$i = $num - 1;
if (sizeof($names) > $i && strlen(trim($names[$i])) > 0) {
return trim($names[$i]);
} else {
return $num;
}
}
function get_form() {
$s = '';
$s = '
Inserisci il numero si squadre OPPURE nome delle squadre</p>' . "\n";
$s .= '<form action="' . $_SERVER['SCRIPT_NAME'] . '">' . "\n";
$s .= '<label for="teams">Numero di squadre</label><input type="text" name="teams" />' . "\n";
$s .= '<input type="submit" value="Genera calendario" />' . "\n";
$s .= '</form>' . "\n";
$s .= '<form action="' . $_SERVER['SCRIPT_NAME'] . '">' . "\n";
$s .= '<div>Oppure</div>' . "\n";
$s .= '<label for="names">Nomi delle squadre(una per linea)</label>'
. '<textarea name="names" rows="8" cols="40"></textarea>' . "\n";
$s .= '<input type="submit" value="Genera Calendario" />' . "\n";
$s .= "</form>\n";
return $s;
}
main();
?>
Questo programma provato in easy php funziona correttamente. Ma quando lo carico sul mio sito nn funziona, praticamente quando inserisco i nomi delle squadre al posto di darmi il calendario mi fa tornare alla home page.
Cosa devo modificare??????
