How to Customize HTML5 Date Field Date Format

When date input was added by HTML5, many believed that it would offer the users a friendly, interactive and known method of entering a date on a website. However; this new addition has failed to live up to the expectations and the major reason behind it remains the fickle nature of the format of the input given by the user.

Originally, the date input attribute was designed as a form element to pick values through a datepicker. The problem however, lies in the implementation of datepicker which changes from browser to browser. What it essentially means is that as a web designer you must be intending to allow user to pick a date in the format YYYY/MM/DD via datepicker and you designed your HTML validations accordingly, but when the user accesses the webpage through the browser on his system, he might see a completely different sequence of selections depending upon the default date settings in his/her system and the browser used.

Now there is no said rule in HTML5 that would allow the web designers to change the format in which the date element picks values. Therefore, the rigidness of the date element prompted designers to look for other ways to alter the format of the date to be entered by the user.

Form Validation Using Jquery Examples

When you include forms on your website for user input, it is always advisable to perform some validation on the data entered. This not only ensures that your application receives the type of data it can work with, but it also makes for good UX (user experience) as users will be able to be warned of the incorrect input and be given hints of the kind of data that is acceptable.

There are two kinds of validation: client-side and server-side validation. It is recommended that you perform both. Client side validation is usually done with JavaScript and it serves to give the user quick feedback on input errors before a call to the server is made with the data. Server side validation serves as a second line of defence against invalid data. Even if you have set up client side validation, you should always perform server side validation as JavaScript can be bypassed.

PHP Form Validation Tutorial

Client-side form validations help in giving immediate feedback to the user. It is also required to add server side form validation in your form processing script. The user can disable Javascript on their server or even auto-bots might try to submit your form as well.

The server side form validations help keeping the form submission data consistent. The validations also help in lesser server side errors. For example, if you have set length limit in the database for a text input, it is better to do the validation before it actually gets cut off by the database system or even getting an error thrown.
