php - 在某些情况下输入表单数组值 null
问题描述
我有一个包含近 13000 个输入（复选框）的大表单，这是 html/smarty 代码，我的问题是在检查表单末尾的复选框（最后一个）时，它们的值始终为空。我像这样调试了 $_POST 值
if (isset($_POST['partsfilter'])) {
$vars = $_POST['partsfilter'];
var_dump($vars[5366]);
var_dump($vars[5368]);
var_dump($vars[5525]); this one return null when it shouldn't be
}
我在 htaccess 文件中试过这个
php_value post_max_size 20M
php_value upload_max_filesize 20M
php_value max_input_vars=15000
但问题始终存在我正在考虑使用 AJAX 从选中的复选框中获取值并提交表单，因为提交的（选中的输入）值不是太多（至少不是 13000）
