CodeIgniter framework prompts the solution to Disallowed Key Characters_PHP tutorial
Opening the source code of the ci framework, it is not difficult to find that there is such a function in the core input class of ci:
function _clean_input_keys($str)
{
if ( ! preg_match("/^[a-z0-9:_/-]+$/i", $str) )
{
exit('Disallowed Key Characters.');
}
{ $ Str = $ this- & gt; UNI-& GT; Clean_string ($ str) (🎜>}
🎜>}
, so an error is thrown
We can rewrite this method in the core of the application
Name it MY_Input.php (the prefix MY_ can be customized in config.php), and then add the following code
Copy code
The code is as follows:
}
function _clean_input_keys($str)
{
if(preg_match("/^,_[a-z0-9 :_/-]+$/",$str)){
$str = preg_replace("/,_/","",$str); preg_match("/^[a-z0-9:_/-]+$/i", $str))
return $str;
}
}

What is Identity in SQL? Specific code examples are needed. In SQL, Identity is a special data type used to generate auto-incrementing numbers. It is often used to uniquely identify each row of data in a table. The Identity column is often used in conjunction with the primary key column to ensure that each record has a unique identifier. This article will detail how to use Identity and some practical code examples. The basic way to use Identity is to use Identit when creating a table.

1. Function Overview Keyspace notification allows clients to receive events that modify Rediskey changes in some way by subscribing to channels or patterns. All commands that modify key keys. All keys that received the LPUSHkeyvalue[value…] command. All expired keys in the db database. Events are distributed through Redis's subscription and publishing functions (pub/sub), so all clients that support subscription and publishing functions can directly use the keyspace notification function without any modifications. Because the current subscription and publishing functions of Redis adopt a fireandforget strategy, if your program

How to implement custom middleware in CodeIgniter Introduction: In modern web development, middleware plays a vital role in applications. They can be used to perform some shared processing logic before or after the request reaches the controller. CodeIgniter, as a popular PHP framework, also supports the use of middleware. This article will introduce how to implement custom middleware in CodeIgniter and provide a simple code example. Middleware overview: Middleware is a kind of request

CodeIgniter Middleware: Accelerating Application Responsiveness and Page Rendering Overview: As web applications continue to grow in complexity and interactivity, developers need to use more efficient and scalable solutions to improve application performance and responsiveness. . CodeIgniter (CI) is a lightweight PHP-based framework that provides many useful features, one of which is middleware. Middleware is a series of tasks that are performed before or after the request reaches the controller. This article will introduce how to use

An unpatchable Yubico two-factor authentication key vulnerability has broken the security of most Yubikey 5, Security Key, and YubiHSM 2FA devices. The Feitian A22 JavaCard and other devices using Infineon SLB96xx series TPMs are also vulnerable.All

Problems encountered: During the development process, you will encounter keys that need to be deleted in batches according to certain rules, such as login_logID (ID is a variable). Now you need to delete data such as "login_log*", but redis itself only has batch query. Command keys for class key values, but there is no command for batch deletion of a certain class. Solution: Query first, then delete, use xargs to pass parameters (xargs can convert pipe or standard input (stdin) data into command line parameters), execute the query statement first, and then remove the queried key value and the original del parameters. delete. redis-cliKEYSkey* (search condition)|xargsr

Introduction to the method of using the database query builder (QueryBuilder) in the CodeIgniter framework: CodeIgniter is a lightweight PHP framework that provides many powerful tools and libraries to facilitate developers in web application development. One of the most impressive features is the database query builder (QueryBuilder), which provides a concise and powerful way to build and execute database query statements.
