In this tutorial I will show you how to do client side validation in the form. Yii ensures to save the input to persistent storage.
Preparation: Let’s imagine there is a company called xyz and has number of employees. Happy Coding 🙂 Client Side Form Validation with Yii Framework Hej, I’m from Bangladesh. Perhaps, that’s why I do not know any closed source language.
Step 1: Creating Database Use the following code to create our table.
-- -- Database: xyz -- CREATE DATABASE xyz; -- -- Select: xyz -- USE xyz; -- -- Table structure for table employees -- CREATE TABLE IF NOT EXISTS employees ( id int(11) NOT NULL AUTO_INCREMENT, name varchar(150) NOT NULL, age int(11) NOT NULL, email varchar(100) NOT NULL, address text NOT NULL, PRIMARY KEY (id) ) ENGINE=Inno DB DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ; This code will create one database called xyz and five fields for our employees table.
When a user enters the correct Captcha code but server-side validation of another field fails, they are shown another Captcha image with a different code.
.action_button.action_button:active.action_button:hover.action_button:focus,.action_button:hover.action_button:focus .count,.action_button:hover .count.action_button:focus .count:before,.action_button:hover .count:before.u-margin-left--sm.u-flex.u-flex-auto.u-flex-none.bullet.
If we allowed multiple retries on solving the same Captcha, it would significantly lower the Captcha security, since bots could just brute-force different code values until they eventually got it right.Client scripting and server scripting serve different purposes.Server scripting, via ASP, can be used to create Hypertext Markup Language (HTML) pages on the fly on the Web server that are then sent to the browser.So basically, if the Captcha validation attempt wasn't successful, the Captcha image also needs to be reloaded and the previous user input cleared, since the old Captcha code has been invalidated.I have a form protected with Bot Detect Captcha that contains several other validated fields.
