Creating a membership based site seems like a daunting task at first. If you ever wanted to do this by yourself, then just gave up when you started to think how you are going to put it together using your PHP skills, then this article is for you. We are going to walk you through every aspect of creating a membership based site, with a secure members area protected by password.
This is in continuation of the tutorial on making a membership based web site. Please see the previous page PHP registration form for more details. Download the code You can download the whole source code for the registration/login system from the link below: RegistrationForm.zip The ReadMe.txt file in the download contains detailed instructions. The login form Here is the HTML code for the login form. <form id='login' action='login.php' method='post' accept-charset='UTF-8'> <fieldset > <legend>Login</legend> <input type='hidden' name='submitted' id='submitted' value='1'/> <label for='username' >UserName*:</label> <input type='text' name='username' id='username' maxlength="50" /> <label for='password' >Password*:</label> <input type='password' name='password' id='password' maxlength="50" /> <input type='submit' name='Submit' value='Submit' /> </fieldset> </form> Logging in We verify the username and the password we received and then look up those in the database.
This tutorial will introduce HTML check boxes and how to deal with them in PHP. Single check box Let's create a simple form with a single check box. <form action="checkbox-form.php" method="post"> Do you need wheelchair access? <input type="checkbox" name="formWheelchair" value="Yes" /> <input type="submit" name="formSubmit" value="Submit" /> </form> In the PHP script (checkbox-form.php), we can get the submitted option from the $_POST array. If $_POST['formWheelchair'] is “Yes”, then the box was checked.
This tutorial will show you how to add select boxes and multi-select boxes to a form, how to retrieve the input data from them, how to validate the data, and how to take different actions depending on the input. Select box Let's look at a new input: a “select” box, also known as a “drop-down” or “pull-down” box. A select box contains one or more “options”. Each option has a “value”, just like other inputs, and also a string of text between the option tags.
This tutorial takes you step by step through web form processing using PHP. You will learn how to collect input from a web form, validate and save it. This tutorial assumes that you are familiar with at least very basic PHP and HTML. Note: You can make web forms quickly with Simfatic Forms. Simfatic Forms helps you to make complete, feature rich forms and get it online quickly. Read more here.
It is very essential to have the input to your form validated before taking the form submission data for further processing. When there are many fields in the form, the PHP validation script becomes too complex. Moreover, since you are doing the same or similar validation for most of the forms that you make, just too much of duplicate effort is spent on form validations. Note: You can make web forms quickly with Simfatic Forms.
In this article shows the usage of PHP_SELF variable and how to avoid PHP_SELF exploits. What is PHP_SELF variable? PHP_SELF is a variable that returns the current script being executed. This variable returns the name and path of the current file (from the root folder). You can use this variable in the action field of the FORM. There are also certain exploits that you need to be aware of. We shall discuss all these points in this article.
This tutorial will cover how PHP handles form data posted via the ‘GET’ method. Introduction to the query string GET data comes from the URL itself, and will typically follow the name of the script file in the URL. The start of GET data is indicated with a question mark (?). The name of the field is followed by an equal sign (=) and the value of the field. Each field is then separated by an ampersand (&).
This tutorial will cover how PHP handles form data posted via the POST method. Introduction to the form POST data is submitted by a form and “posted” to the web server as form data. POST data is encoded the same way as GET data, but isn't typically visible to the user in standard browsers. Most forms use the post method because it “hides” the form data away from the user and doesn't clutter up the URL in the address bar.
