Validating data in php form

To validate is to ensure the data you've requested of the user matches what they've submitted.

There are several core methods you can use for input validation; usage obviously depends on the type of fields you'd like to validate. Say we have an input area in our form like this: Just like that, we've told the browser to only allow up to five characters of input, but there's no limitation on what characters they can input. If we're saving to the database, there's no way we want to give the user unrestricted write access. When processing the form, we'll write code to check each field for its proper data type.

This commonly comes up when building a settings page for your theme, creating and manipulating shortcodes, or saving and rendering extra data associated with a post.

There's a distinction between how input and output are managed, however.

Here is the client side form validation code: Once the contact form is submitted, the form submission data is sent to the script mentioned in the action attribute of the form (in our form).Whether you like it or not, forms are a major apart of every web developer’s life.If you think about it, most of what we do is based on receiving and validating data that has been sent to us by the client.The ‘contact us’ form provides an easy interface through which your visitors can communicate to you.Your visitors can quickly submit their views, opinions and suggestions about your website , product or service.

The script then will collect the form submission data, validate it and send the email. Ensure that the mandatory fields are filled-in, and that the email is in proper format. After sending the email, the visitor is redirected to the ‘thank you’ page.
