过滤多个复选框php的更好方法
我正在尝试制作一个php，mysql简单的复选框过滤器。
因此，复选框有3个部分，用户需要至少选择其中任何一个以显示结果。
我的代码

现在我手动完成了用户可以做的所有情况，在我的方法中有很多重复，如果没有复选框增加它将很难统计所有情况
1 个答案:
答案 0 :(得分：1)
我觉得某些事情在某个地方变得越来越复杂。
我将专注于这个陈述......
因此，复选框有3个部分，用户需要至少选择其中任何一个以显示结果。
在此示例中，我有三组复选框category[branch]，category[batch]和category[year]。如果不选择集合中的项目，则post变量不存在并通过isset()和count()验证。
/！ \本代码不是SQL注入安全
<?php
if( $_SERVER['REQUEST_METHOD'] === 'POST')
{
if( isset( $_POST['category'] ) === true and count( $_POST['category'] ) === 3 )
{
$category = array_keys( $_POST['category'] );
$selections = call_user_func_array('array_merge', $_POST['category']);
$where = array();
foreach( $_POST['category'] as $key => $value )
{
$where[] = $key . " IN ('" . implode("','",$value)."') ";
}
echo 'three areas selected; ' . implode( ', ', $category );
echo 'you selected: ' . implode( ', ', $selections );
echo 'WHERE ' . implode( ' AND ', $where );
}
else
{
echo 'please select atleast any one of each category';
}
}
?>
