Quiz 4: Handling User Input

Autoglobal array elements are referred to with an index number.

You must use the global keyword to reference a global variable within the scope of a function.

When using the variable name as an index for the $GLOBALS array, you omit the leading dollar sign from the name.

The method attribute defines how the form data is submitted to the server.

The value of the method attribute will be either post or get.

When the form data is submitted using the get method, the form data is appended to the URL specified in the form's method attribute.

When a form's submit button is pressed, each field on the form is sent to the Web server as a name/value pair.

When the post method is used to submit a form, the name portion of the name/value pair becomes the value assigned to the array element.

When using the get method to submit form data, the form data is separated from the URL by a colon. (:).

The get method restricts the number of characters that can be appended to a URL to 255.

PHP includes a feature called magic quotes, which automatically adds a backslash (\) to any single quote, double quote, or NULL character in submitted form data.

By default, magic_quotes_gpc is the only magic quote directive enabled in the php.ini configuration file.

The alternate method to escape strings is the stripslashes() function.

The blank() function can be used to determine if a value was entered in a form.

The best way to ensure valid form data is to build the Web form with controls that only allow the user to enter acceptable responses

The round() function can be used to ensure that numbers have the appropriate number of digits after the decimal point, if any.

Regular expression functions are some of the best tools for verifying string data meets the strict formatting required for email addresses.

A good programming practice is to stop processing a form when an error is found and display the error to the user.

A sticky form is redisplayed with the values that the user entered the last time the form was submitted.

With complex escaping from XHTML, you close one PHP block, insert some XHTML elements, and then open another PHP block to continue the script.

In PHP, an e-mail message is sent using the email() function.

The subject argument of the mail function must be plain text without XHTML tags or character entities.

From, Cc, Bcc and Date headers are examples of additional headers.

The mail() function returns a value of TRUE if the message was sent successfully and FALSE if it was not.

In an all-in-one form, when the user clicks the submit button, the script submits the form to a separate processing script.

The issent() function can be used to determine if the $Submit variable has been set (if the Submit button has been pressed).

The unset() function is used to uninitialize a variable after it has been set.

The post method is ideal for embedding options in a hyperlink.

When using text hyperlinks to navigate within a Web page template, the values that specify which dynamic content to show must be appended to the filename in the "href" attribute of the anchor tag.

You cannot use buttons to target content to a dynamic section of a Web page template.
