Validating input php
We are using this function to check if all the text fields are empty or not.We are using isset() to check the gender radio button is checked or not.But I will say that validating your input is the first step to ensuring that the code you have written will be executed as intended.Maybe you are coming to PHP from another language and you might be thinking, “this was never an issue before so why should I care?Here, we are going to see how to validate a form using PHP. We are going to check these validations in server side.
Since our web application allows outsiders to enter data, server side form validation is also required for additional security.
We are validating email format by using PHP filter_var() function.
The code is, $value) /* Validation to ensure gender is selected */ if(!
Many applications do not plan input validation, and leave it up to the individual developers.
This is a recipe for disaster, as different developers will certainly all choose a different approach, and many will simply leave it out in the pursuit of more interesting development.
