PHP处理大量表单字段的便捷方法
这篇文章主要介绍了PHP处理大量表单字段的便捷方法,本文讲解一种使用数组的方式来快速、方便的处理大量表单数据,需要的朋友可以参考下
关于程序开发中的表单批量提交策略
很多时候一个表单太多的字段,如何能够高效获取表单字段,也为如何提神开发的效率和统一性?
比如一个系统的某个有26个字段,,那么我用表单的名称用26个a到z的字母,
你是选择 ,,……,的传统形式来做吗?
但是这种情况下如果做批量数据插入就不会有那么简洁了,
因为插入或者编辑操作会是这样的语句:特别是这样长得蛋疼的SQL字符串更悲催。
复制代码 代码如下:
$sql="INSERT kele_table(a,b,……,z) value(a='$a',b='$b',……,z='$z')";//这样写很长铁牛用省略号标示
$sql="UPDATE SET kele_table(a='$a',b='$b',……,z='$z') where id=$id";
这样子写的话挺折腾的,字符串太长
用下面一种方法更好:
要点1:对整个提交的表单字段使用数组模式。
复制代码 代码如下:
,……,
要点2:
PHP后台程序通过POST接收$setting数组
要点3:
插入表单字段展示
复制代码 代码如下:
$fields=array('a','b',……,'z');//这个是特意设置校验字典,校验提交的字段是否存在
foreach($setting as $k=>$v) {
if(in_array($k, $fields)) { $sqlk .= ','.$k; $sqlv .= ",'$v'"; }
}
$sqlk = substr($sqlk, 1);
$sqlv = substr($sqlv, 1);
$sql="INSERT INTO kele_table ($sqlk) VALUES ($sqlv)";
更新表单字段展示
复制代码 代码如下:
$sql = '';
foreach($setting as $k=>$v) {
if(in_array($k, $fields)) $sql .= ",$k='$v'";
}
$sql = substr($sql, 1);
$sql="UPDATE kele_table SET $sql WHERE id=$id";

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
