Lab 7

For this lab you will create a ContactPage and a ContactForm class that will include the following features.

contact.php

You will generate a Contact Page given by the inclass example PageLib.php. Create a ContactPage class that extends Page object. The ContactPage class will have a public member variable $form assigned to a new ContactForm object by default, which you will define a class in a seperate file called ContactFormLib.php and require within this ContactPage.php. Override the Page's displayPage() function such that you will call a member function displayContactForm passing it's member variable form. Within this function you will call the ContactForm object's member function displayForm().

ContactFormLib.php

You will create a class called ContactForm that will contain a member variable for action='contact.php' and method='POST' four member functions: addLabel, addInput, addTextArea, and displayForm.

• displayForm() - the driver function that will display a html form. Use the member variables $action and $method within the open tag of the form. Add three input tags with a label for each one, a text area with a label, and a submit button. You will have an input tag for: name, email, and phone; a textarea for the user's contact message, and a button to submit the form [addInput("submit",...)]
• addLabel($label, $for) - this function will output an html label. The first parameter will act as a title for the input, and the second parameter will be the corresponding id of the input element.
• addInput($type, $id, $name, $placeholder='', $value='', $required=true) - this function will output an html input tag and fill in the attributes with the given parameters.
• addTextArea($id, $name,$placeholder='', $rows=8, $cols=40, $required=true) - This function will output an html textarea tag and fill in the attributes with the given parameters.

Once the form has been submitted [if(isset($_POST))] validate that all the required fields were not empty. If so, assign the $contactpage's member variable content to display "Thank you ... $name, $email, $phone, and $message". Otherwise display the form.

Put all of these scripts into your ~/3680_S18/wk7/ depository directory, which I'll extract and copy all of them at the time of the due date.
