phpMyAdmin Database Fields
You have four Fields in your table from the previous lesson Although they are set out in rows in the images, the rows are actually
the Columns you saw earlier – the Fields. Each Field needs a name. So go
ahead and type the following for your Field names:
Create a database with phpMyAdmin
You can create all of your database tables and queries using PHP code. But
before doing that, it's a good idea to get an understanding of just what it
is you'll be creating. If you're new to the world of databases, then here's
a simple primer.
A database is a way to store lots of information. You might want to store the
names and addresses of all your contacts, or save usernames and passwords for
your online forum. Or maybe customer information.
When you create a database, you're creating a structure like this:
What is a database and what do they look like?

Getting values out of PHP functions
When you're creating your own functions, you may notice that they can be broken
down in to two categories: functions that you can leave, and just let them do
their jobs; and functions where you need to get an answer back. As an example,
here's the two different categories in action:
print ("Get on with it!");
$string_length = strlen($string_length);
$string_length = strlen($string_length);
Check for blank Textboxes with PHP
f you remember the script that we wanted to create earlier it was this:
- Get the text that a user entered in a textbox on a form
- Trim any blank spaces from the left and right of the text
- Check that what you have left is not a blank string
<?PHP
PHP Functions and Arguments
Arguments
Functions can be handed variables, so that you can do something with what's inside of them. You pass the variable over to your functions by typing them inside of the round brackets of the function name.
<?PHP
$error_text = "Error message";
display_error_message($error_text);
display_error_message($error_text);
function display_error_message($error_text) {
print $error_text;
PHP Functions
What is a Function?
A function is just a segment of code, separate from the rest of your code. You separate it because it's nice and handy, and you want to use it not once but over and over. It's a chunk of code that you think is useful, and want to use again. Functions save you from writing the code over and over. Here's an example.Suppose you need to check text from a textbox. You want to trim any blank spaces from the left and right of the text that the user entered. So if they entered this:
" Bill Gates
"
You want to turn it into this:Sorting PHP Array values
There may be times when you want to sort the values inside of an array. For
example, suppose your array values are not in alphabetical order. Like this
one:
$full_name = array();
$full_name["Roger"] = "Waters";
$full_name["Richard"] = "Wright";
$full_name["Nick"] = "Mason";
$full_name["David"] = "Gilmour";
$full_name["Richard"] = "Wright";
$full_name["Nick"] = "Mason";
$full_name["David"] = "Gilmour";
Geting Values from Arrays
Here's an example for you to try:
<?php
$seasons = array("Autumn", "Winter",
"Spring", "Summer");
print $seasons[0];
print $seasons[0];
?>
The array is the same one we set up before To get
at what is inside of an array, just type the key number you want to access.
In the above code, we're printing out what is held in the 0 position (Key) in
the array. You just type the key number between the square brackets of your
array name:
print $Array_Name[0];
How to Set up a PHP Array
First you type out what you want your array to be called ($Order_Number,
in the array above) and, after an equals sign, you type this:
You can use two basic methods to put something into an array.
array( );
So setting up an array just involves typing the word array followed by a pair
of round brackets. This is enough to tell PHP that you want to set up the array.
But there's nothing in the array yet. All we're doing with our line of code
is telling PHP to set up an array, and give it the name $Order_Number. You can use two basic methods to put something into an array.
PHP Arrays
You know what a variable is – just a storage area where you hold numbers
and text. The problem is, a variable will hold only one value. You can store
a single number in a variable, or a single string. An array is like a special
variable, which can hold more than one number, or more than one string, at a
time. If you have a list of items (like a list of customer orders, for example),
and you need to do something with them, then it would be quite cumbersome to
do this:
$Order_Number1 = "Black shoes";
The PHP break statement
There are times when you need to break out of a loop before the whole thing
gets executed. Or, you want to break out of the loop because of an error your
user made. In which case, you can use the break statement. Fortunately, this
involves nothing more than typing the word break. Here’s some not
very useful code that demonstrates the use of the break statement:
$TeacherInterrupts = true;
$counter = 1;
$counter = 1;
while ($counter < 11) {
PHP Do ... While loops
This type is loop is almost identical to the while loop except that the condition comes at the end:
do
statement
while (condition)
The difference is that your statement gets executed at least once. In a normal
while loop, the condition could be met before your statement gets executed.
PHP While Loops
Instead of using a for loop, you have the option
to use a while loop. The structure of a while loop is more simple than a for
loop, because you’re only evaluating the one condition. The loop goes round
and round while the condition is true. When the condition is false, the programme
breaks out of the while loop. Here’s the syntax for a while loop:
while (condition) {
statement
PHP For Loops
So what’s a loop then? A loop is something that goes round and round.
If I told you to move a finger around in a loop, you’d have no problem
with the order (unless you have no fingers!) In programming, it’s exactly
the same. Except a programming loop will go round and round until you tell it
to stop. You also need to tell the programme two other things - where to start
your loop, and what to do after it’s finished one lap (known as the update
expression).
You can programme without using loops. But it’s an awful lot easier with them. Consider this.
You want to add up the numbers 1 to 4: 1 + 2 + 3 + 4. You could do it like this:

PHP and HTML Checkboxes
Note one thing about the HTML checkbox elements: they all have different NAME
values (ch1, ch2 ch3, etc). When we coded for the Radio Buttons, we gave the
buttons the same NAME. That's because only one option can be selected with Radio
Buttons. Because the user can select more than one option with Checkboxes, it
makes sense to give them different NAME values, and treat them as separate entities
(but some advocate treating them just like Radio Buttons).
In your PHP code, the technique is to check whether each checkbox element has been checked or not. It's more or less the same as for the radio Buttons. First we set up five variable and set them all the unchecked, just like we did before:

PHP and HTML Radio Buttons
Make sure you save your work as radioButton.php, as that's where
we're posting the Form – to itself.
To get the value of a radio button with PHP code, again you access the NAME
attribute of the HTML form elements. In the HTML above, the NAME of the Radio
buttons is the same – "gender". The first Radio Button has
a value of "male" and the second Radio Button has a value of female.
When you're writing your PHP code, it's these values that are returned. Here's
some PHP code. Add it to the HEAD section of your HTML:The HTML ACTION attribute and PHP
You don't have to submit your form data to the same PHP page, as we've been
doing. You can send it to an entirely different PHP page. To see how it works,
try this:
Create the following page, and call it basicForm2.php. This is your HTML. Notice the ACTION attribue.

<html>
<head>
<title>A BASIC HTML FORM</title>
</head>
<head>
<title>A BASIC HTML FORM</title>
</head>
PHP Submit buttons
In the previous lesson you saw how to get text
from a textbox when a Submit button on a form was clicked. However, when you
first load the page the text still displays.
The reason why the text displays when the page is first loaded is because the script executes whether the button is clicked or not. This is the problem you face when a PHP script is on the same page as the HTML, and is being submitted to itself in the ACTION attribute.

PHP and Text Boxes on HTML Forms
If you've been following along from the in the previous lesson
then your basicForm.php now has a METHOD and ACTION set. We're going
to use these to process text that a user has entered into a text box. The
METHOD attribute tells you how form data is being sent, and the ACTION
attribute tells you where it is being sent.
To get at the text that a user entered into a text box, the text box needs
a NAME attribute. You then tell PHP the NAME of the textbox you want to work
with. Our text box hasn't got a NAME yet, so change HTML TO THIS
PHP and the Submit Button of HTML Forms
The HTML Submit button is used to submit form data to the script mentioned
in the ACTION attribute. Here's ours:
<Form Name ="form1" Method ="POST" ACTION
= "basicForm.php">
So the page mentioned in the ACTION attribute is basicForm.php. To Submit this
script, you just need a HTML Submit button:
<INPUT TYPE = "Submit" Name = "Submit1"
VALUE = "Login">
PHP and the Action Attribute of HTML Forms
The Action attribute is crucial. It means, "Where do you want the form
sent?". If you miss it out, your form won't get sent anywhere. You can
send the form data to another PHP script, the same PHP script, an email address,
a CGI script, or any other form of script.
In PHP, a popular technique is to send the script to the same page that the form is on – send it to itself, in other words. We'll use that technique first, but you'll see both techniques in action.

PHP and the Post Attribute of HTML Forms
<FORM NAME ="form1" METHOD ="POST"
ACTION = "">
The ?Submit1=Login part from the previous section is now gone! That is because
we used POST as the method. Using POST means that the form data won't get
appended to the address in the address bar for all to see. We'll use both
POST and GET throughout the book. But it depends on the project: if the data
is not sensitive then use GET, otherwise use POST.
PHP and the Method Attribute of HTML Forms
<FORM NAME ="form1" METHOD ="
" ACTION = "">
The Method attribute is used to tell the browser how the form information should be sent. The two most popular methods you can use are GET and POST. But our METHOD is blank. So change it to this:

<FORM NAME ="form1" METHOD ="GET"
ACTION = "">
To see what effect using GET has, save your work again and then click the Submit
button on your form. You should see this:HTML Forms and PHP
If you know a little HTML, then you know that the FORM tags can be used to
interact with your users. Things that can be added to a form are the likes of
text boxes, radio buttons, check boxes, drop down lists, text areas, and submit
buttons. A basic HTML form with a textbox and a Submit button looks like this:
<html>
<head>
<title>A BASIC HTML FORM</title>
</head>
<body>

PHP Booleans
A Boolean value is one that is in either of two states. They are known as True
or False values, in programming. True is usually given a value of 1, and False
is given a value of zero. You set them up just like other variables:
$true_value = 1;
$false_value = 0;
$false_value = 0;
PHP Logical Operators
As well as the PHP comparison operators you saw earlier, there's also something
called Logical Operators. You typically use these when you want to test more
than one condition at a time. For example, you could check to see whether the
username and password are correct from the same If Statement. Here's the table
of these Operands.
PHP Switch Statements
To see
how switch statements work, study the following code:
<?php
$picture ='church';
switch ($picture) {
case 'kitten':
print('Kitten Picture');
break;
break;
case 'church':
print('Church Picture');
break;
break;
}
PHP Less Than, Greater Than
The Less Than ( < ) and Greater Than ( > ) symbols come in quite handy.
They are really useful in loops (which we'll deal with in another section),
and for testing numbers in general.
Suppose you wanted to test if someone has spent more than 100 pounds on your site. If they do, you want to give them a ten percent discount. The Less Than and Greater Than symbols can be used. Try this script. Open up your text editor, and type the following. Save your work, and try it out on your server.

PHP Not Equal To
PHP Not Equal To
In the previous you saw what Comparison
Operators were. In this lessons, we'll explore the Comparison Operator for
Not Equal To: !=.So open up your text editor, and add the following script:
<?PHP
$correct_username = 'logmein';
$what_visitor_typed = 'logMEin';
$what_visitor_typed = 'logMEin';
if ($what_visitor_typed != $correct_username) {
print("You're not a valid user of this site!");
PHP Comparison Operators
PHP Comparison Operators
You saw in the last section how to test what is inside of a variable. You used if, else … if, and else. You used the double equals sign (==) to test whether the variable was the same thing as some direct text. The double equals sign is known as a Comparison Operator. There a few more of these “operands” to get used. Here’s a list. Take a look, and then we’ll see a few examples of how to use them.

PHP if ... else if Statements
PHP if ... else if Statements
The Syntax of if…else if is as follows………
If (condition){
Print (“out put”);}
if ... else Statements in PHP
The syntax for the if else statement is this:
if (condition_to_test) {
}
else {
else {
}
If you look at it closely, you’ll see that you have a normal If Statement
first, followed by an “else” part after it. Here’s the “else”
part:
else {
}
Again, the left and right curly brackets are used. In between the curly brackets,
you type the code you want to execute. In our code, we set up two variables:
$kitten_image = 0;
$church_image = 1;
$church_image = 1;
PHP If Statements
You saw in the last section that variables are storage areas for your text
and numbers. But the reason you are storing this information is so that you
can do something with them. If you have stored a username in a variable, for
example, you'll then need to check if this is a valid username. To help you
do the checking, something called Conditional Logic comes in very handy indeed.
In this section, we'll take a look at just what Conditional Logic is. In the
next section, we'll do some practical work.
