from的enctype="multipart/form-data"

php版本5.6.6

问题:部分POST数据接收不到

追源代码发现是php中max_input_vars配置造成的;

技术分享

相关函数为rfc1867_post_handler,如果超过长度,则不会调用safe_php_register_variable来进行变量注册

 

相关堆栈如下
#0  rfc1867_post_handler (
    content_type_dup=0x7ff85307a5f8 "multipart/form-data; boundary=", ‘-‘ <repeats 27 times>, "306141311912057",
    arg=0x7ff85307ccc0) at /tmp/php-5.6.2/main/rfc1867.c:681

其中rfc1867_post_handler为php_session_rfc1867_callback

 

解决办法:

在php.ini中将max_input_vars调大改为5000就可以了
