Question

注意到如果我不选择复选框并提交，我会收到这些错误：

Warning: implode() [function.implode]: Invalid arguments passed in /home/content/o/l/t/oltvcb/html/feedback_mtg.php on line 148

Warning: Cannot modify header information - headers already sent by (output started at /home/content/o/l/t/oltvcb/html/feedback_mtg.php:148) in /home/content/o/l/t/oltvcb/html/feedback_mtg.php on line 162

我注意到表格数据实际上是在我的电子邮件中发现的......

与“选项”字段

有关

以下是表单代码：

Answer 1

除了一些严重可怕的代码之外，修复错误代替了这一行：

$options = $_POST['options'] ;

有了这个：

$options = array();
if(isset($_POST['options'])) {
    $options = $_POST['options'];
}

错误基本上是每当你没有选择一个选项$options没有被设置为一个数组时，所以当你尝试对它进行implode时，PHP会因为期待一个数组而感到不快。 / p>

Answer 2

if (isset($_POST['options'])
{
    implode(...)
}

我选择这个......这一个将所有内容封装在一个函数中。
