Forms in PHP

As in HTML, the form elements are enclosed within <form> tags. Here is a small example.

The form element takes two values, First is the form's "action" that tells to which script the data has to be sent. In the example above it is "process.php". It can also be in the form of URL (e.g. http://www.vyom.co.in/scripts/private/processors/process.php) Second is the "method" which tells the form how to send the data. POST method sends data in data stream, and maintains it as a secret. like password GET method is used to send data making visible to users. For example if we are sending a name=george then it would look like (e.g. http://www.vyom.co.in/process.php?name=george)

The variable that the form passes on by POST method is collected using $_POST. In the following example it takes variable from the POST and assigns it to the variable $name

If we are using GET method to pass the data then should use the following code.

For each variable that is passed from form, we should follow the above procedure.

The following code is to create a system which will e-mail a user's comments to you.

The above code is used to make a simple form, where a user can enter their e-mail address. name and comments if any. Here can add extra parts if required. After adding remember to update the php script too.

here we have used [email protected], You should replace it with your own e-mail address. save the script as mail.php and upload both the files. And now just fill in your comment box.

First part of the script stops the spammers from using your form to send their spam messages. this is done by checking for special characters not present in the input that can be used to trick the computer into sending messages to other addresses. It is this function which checks for these characters. and if they are found, stops running the script.
