Forms are exposed to anyone who visits your site, including malicious visitors. These malicious users or bots try to inject harmful code into your system. The code entered can steal legitimate user credentials, access to databases and servers. So it is very important to clear data before doing anything. Most programming languages ​​have some sort of cleanup facility. In PHP applications, sanitizing input is as easy as passing a value to a built-in function. Let’s start by clearing the input (

Custom Data Validation

To make sure everything is correct, let’s start by displaying all the data we got from the contact form.

I have confirmed that the form works. Time to select each input from $_POST and clean up before continuing. For this we use the filter_var() function. This filter function replaces the passed variable name with

Returns a sanitized value. In this example, we clear each field one by one, but you can use filter_var_array() to quickly remove malicious data.

Contact If he’s ever used a form, he’s likely experienced an overwhelming amount of spam. To keep your inbox free from spam, you need to implement some form of spam prevention. The quickest and easiest solution is the honey pot technique. This is the oldest trick in the book and easy to do. Basically I added a hidden field to my contact form and expect only bots to fill this field as it is not visible to legitimate users. This method protects her web form from major spambots. As you can imagine, nothing prevents the bot from detecting this hidden field and avoiding entering it. It also attracts manual spammers who can easily bypass all the client’s spam filtering methods when the website traffic starts to grow. This is where the API comes in, handling all form submissions internally and never interacting with the visitor.

.To make sending requests easier, we’ll use the popular GuzzleHttp library to create HTTP requests. You can install Guzzle using Composer. If you’re not familiar with Composer, it’s a dependency manager for PHP.
