Symfony2未定义偏移：0彩票项目错误

Question

在我的彩票项目中，我有5张门票，您可以在其中选择数字并购买。问题是，如果你为了买他们...例如，你只能买到门票：

Ticket 1 Ticket 2 Ticket 3 Ticket 4 Ticket 5 

如果添加号码票1，然后其他人它的工作原理...如果你跳过ticket 1并添加数字给其他人，当你试图购买你得到这个错误：

ContextErrorException：注意：未定义偏移量：0在C：\ wamp \ www \ Digidis \ front \ src \ MediaparkLt \ UserBundle \ Service \ MoneyManager.php line 313

完整堆栈：

array('cartProduct' => array('title' => 'EUROMILLONES', 'price' => '2.35', 'product' => '2', 'ticket_id' => '1433921783_19792', 'numbers' => '8,13,14,17,37', 'stars' => '4,7', 'betslip' => '{"duration":"1","subscription":"false","jsPrice":"235","type":"simple","numbers1":"0,0,0,0,0","numbers2":"8,13,14,17,37","numbers3":"0,0,0,0,0","numbers4":"0,0,0,0,0","numbers5":"0,0,0,0,0","stars1":"0,0","stars2":"4,7","stars3":"0,0","stars4":"0,0","stars5":"0,0","dayOfWeek":"3"}', 'is_syndicate' => false, 'draw' => object(DateTime)), 'product' => object(Product), 'user' => object(User), 'reference' => null, 'paymentResult' => 'Authorised', 'bets' => object(stdClass), 'individualBets' => array(), 'tickets' => array(array('numbers' => '8,13,14,17,37', 'stars' => '4,7')), 'k' => '0', 't' => array('numbers' => '0,0,0,0,0', 'stars' => '0,0'), 'is_ticket_filled' => false, 'week_id' => array(array('ticketId' => '7005')), 'g' => '0', 'lastId' => '7005', 'purchase' => object(Purchase), 'price' => '2.35', 'bet' => object(Bet), 'euromillonesBet' => object(EuromillonesBet), 'drawDate' => array(object(DrawDate)), 'j' => '0')) in C:\wamp\www\Digidis\front\src\MediaparkLt\UserBundle\Service\MoneyManager.php line 313 

正如你可以看到第一张票，它是空的（或0），这就是为什么它会导致错误...我怎样才能让它跳过空的票？

这里是哪里发生错误的控制器：

Answer 1

从我看到你的对象投注类型设置为"type":"simple"和numbers1":"0,0,0,0,0"

$is_ticket_filled = ((int) str_replace(',', '', $t['numbers'])) > 0; 
//(int) 00000 = 0 
if (!$is_ticket_filled) { 
    unset($tickets[$k]); 
} 

导致问题，因为没有设置呢不重置数组索引。 http://ideone.com/5q74Wv

再后来你遍历索引时重复使用使用unset($tickets[$k])

if ($bets->type === 'simple') { 
    //... 
    $tickets = array_values($tickets); 
} 

或检查车票后存在for($k=0; $k < count($tickets); $k++)

而应该重订阵列

$ticketCount = count($tickets); 
for ($k=0; $k < $ticketCount; $k++) { 
    if (false === isset($tickets[$k]) { 
     continue; 
    } 
    //... 
} 

或者更容易，使用迭代现有的门票数组而不是for。

foreach ($tickets as $k => $ticket) { 
    //... 
} 

然后只用$ticket因为$k，不使用其他任何地方改变$tickets[$k]。
