$_GET Help needed

[AchillesForce]

Hello, I've been learning PHP for about 3 weeks now and I've came across a problem. I'm fairly new at this PHP stuff, and I'd appreciate some help.

 

What I got:

 

Index.php

<?php
@$uct = $_GET['uct'];	/* gets the variable $uct */
if (!empty($uct)) {
$uct .= '.php';
include($uct);
}	/* if $uct has a value, include it */
else {
include('home.php');
} 	/* otherwise, include the default uct */
?>

 

Home.php

<?php
$default = "This is the default code I want to show"
$1 = "This is going to be The content if ID = 1"
$2 = "This is going to be The content if ID = 2"
$3 = "This is going to be The content if ID = 3"
$4 = "This is going to be The content if ID = 4"
?>

 

Profiles.php

<?php
$default = "This is the default code I want to show"
$1 = "This is going to be The content if ID = 1"
$2 = "This is going to be The content if ID = 2"
$3 = "This is going to be The content if ID = 3"
$4 = "This is going to be The content if ID = 4"
?>

 

What I would like:

I'd like to be able to access the data I want by sorting it in my navigation. Something like index.php?uct=home&id=2 Or even index.php?uct=profiles&id=2

 

Thanks in advanced!:

I appreciate anyone's help or suggestions. If someone could show me how to write out the code so it works how I want it, that'd be great! Once again, thanks in advance.

You mean something like this:

<?php
if (is_int($_GET['id'])){
switch ($_GET['id']){
	case 1:
		$output = "This is going to be The content if ID = 1";
		break;
	case 2:
		$output = "This is going to be The content if ID = 2";
		break;
	case 3:
		$output = "This is going to be The content if ID = 3";
		break;
	case 4:
		$output = "This is going to be The content if ID = 4";
		break;
	default:
		$output = "This is the default code I want to show";
}
echo $output;
}
else{
exit("invalid ID number");
}

?

@jonsjava:

 

watch using is_int() .. vairables passed via forms and urls are passed as strings, not integers, therefore, is_int() will return false (invalid id number) in the example you provided.

 

better to use is_numeric() (not much of a choice in this matter), and use is_int() if testing integers within your scripts.

Or ctype_digit, or filter_input(INPUT_GET, 'id', FILTER_VALIDATE_INT, array('options' => array('min_range' => 1, 'max_range' => 4))) for a slightly (ahem) more verbose option.

they all have their uses.  one is straight integers, one is string or integer, and one is straight strings.

Like I have stated before, I'm not too good at PHP, but I can read what you have posted, and I am looking for something like that.

But I tried the code you gave me, with the link "index.php?uct=home&id=2" and I still got no luck

Any more suggestions?

switch out this line:

 

if (is_int($_GET['id'])){

 

with:

 

if (ctype_digit ($_GET['id'])){

[AchillesForce]

switch out this line:

 

if (is_int($_GET['id'])){

 

with:

 

if (ctype_digit ($_GET['id'])){

That worked, but now if you dont have an ID with the page, it'll show an error. I fixed this by adding a @. Check it out

<?php
if (@ctype_digit ($_GET['id'])){
   switch ($_GET['id']){
      case 1:
         $output = "This is going to be The content if ID = 1";
         break;
      case 2:
         $output = "This is going to be The content if ID = 2";
         break;
      case 3:
         $output = "This is going to be The content if ID = 3";
         break;
      case 4:
         $output = "This is going to be The content if ID = 4";
         break;
      default:
         $output = "This is the default code I want to show";
   }
   echo $output;
}
else{
   echo("invalid ID number");
}
?>

 

Deff worked. Will be using the forum more, so look out for me!

Thanks once again for everything!

[mrMarcus]

just lose the initial IF statement and use the 'default:' within the switch():

 

<?php
   switch (ctype_digit ($_GET['id'])){
      case 1:
         $output = "This is going to be The content if ID = 1";
         break;
      case 2:
         $output = "This is going to be The content if ID = 2";
         break;
      case 3:
         $output = "This is going to be The content if ID = 3";
         break;
      case 4:
         $output = "This is going to be The content if ID = 4";
         break;
      default:
         $output = "This is the default code I want to show";
   }
   echo $output;
?>

 

what happens is that the switch() statement matches the condition to the appropriate case within the switch, and if there are no matches, it uses the default.

Even better!

Heads up mrMarcus, you'll probably be getting PMed when I need PHP help! haha

Thanks a lot bud.
