The $_GET Function
The built-in $_GET function is used to collect values from a form sent with
method="get".
Information sent from a form with the GET method is visible to everyone (it
will be displayed in the browser's address bar) and has limits on the amount of
information to send (max. 100 characters).
Example
<form action="welcome.php" method="get">
Name: <input type="text" name="fname" />
Age: <input type="text" name="age" />
<input type="submit" />
</form>
|
When the user clicks the "Submit" button, the URL sent to the
server could look something
like this:
|
http://www.w3schools.com/welcome.php?fname=Peter&age=37
|
The "welcome.php" file can now use the $_GET function to collect form data
(the names of the form fields will automatically be the keys in the $_GET
array):
Welcome <?php echo $_GET["fname"]; ?>.<br />
You are <?php echo $_GET["age"]; ?> years old!
|
When to use method="get"?
When using method="get" in HTML forms, all variable names and values are displayed in the URL.
Note: This method should not be used when sending passwords or other sensitive information!
However, because the variables are displayed in the URL, it is possible to
bookmark the page. This can be useful in some cases.
Note: The get method is not suitable for large variable values;
the value cannot exceed 100 characters.
