我有这个提交罚款的表格。问题是我想确保表单字段不是空白。现在，当它被提交为空白时，它会在“support1”表单字段旁边显示错误消息。但它仍然发布到数据库！不知道为什么它会忽略并继续使用else语句。

答案 0 :(得分：0)
您可以使用isset()检查输入是否存在，并使用empty()检查输入是否为空。例如：
if(isset($_POST['take5']) && !empty($_POST['take5'])) {
$take5 = trim($_POST['take5']);
} else {
// empty input, do something else
// e.g. show error
}
注意：您可能需要转义输入以放入SQL
答案 1 :(得分：-1)
在应填写的输入字段上使用选项required="required"。此外，您可以使用@$_POST['var']忽略这些消息。
