PHP/MySQL Course

Read about simple form procession from page 201 to 205 top two lines.

Notes:

• The $_POST array global variable is automatically filled in from the from fields and the submit button.
• All the data in the $_POST array are strings
• This part of the chapter covers the two part form. One part is the form, and the processing of the form is in a separate php file
• The php file that processes the form must compose a web page to send back to the user, this is usually just a confirmation of the form data being received. We will learn later in this lesson, that you can just redirect to another page after processing without generating a page.
• Note that the option input builds an array of answers, and this array is a element in the $_POST array with the key set by the name attribute of the select tag. And the name must end in [] for it to work. (p204 line 10)

The author uses plain text prior to the text fields to label them, this is old school and you should not do it. Use the new label tag instead.

Read this short page about the label tag: The HTML Label Tag

Also play my video: PHP Form protocol for more information on how forms are processed.

Question:
With this form, which php expression would look up the age entered from the computeAge.php program?

<form action='computeAge.php' method='POST'>
<p><label for= 'age'>Type the age of your car: </label>
<input type='text' name='carage' id='age' /></p>
<p><input type='submit' value='submit' /></p>
