Now onto the tutorial, if you could call it that.
This is useful for when you have a user access restriction to certain pages, and you dont want to use numbers, which at some point, might get a lil confusing. You may start to wonder if, 1 = admin or 5 = guest. Or the other way around.
You might start to clutter up with something like this.For Example.
CODE
$USER_LOGGED_IN means nothing, in this tutorial.But it can be interpreted as a replacement for the user's name/id that is logged in at the moment from a COOKIE/SESSION that is initialized by the user.
CODE
if(UserAuthentication($USER_LOGGED_IN, 0)){ // Zero (0) Being the access needed
echo("Welcome Member");
}
echo("Welcome Member");
}
With this example, you can define the variable so that it can be identified easily.For Example it could be done like this.
CODE
if(UserAuthentication($USER_LOGGED_IN, $user_access['member'])){ // $user_access["name"] Being the access needed
echo("Welcome Member");
}
echo("Welcome Member");
}
But that still wouldnt look nice.
But with this code below...
CODE
<?php
$USER_ACCESS = array(); // Create User Access Array
// Create Access List Array
$access_levels = array("0" => "Guest",
"1" => "Member",
"2" => "Special Member",
"3" => "Global Moderator",
"4" => "Administrator");
// Insert Access List into the User Access Array
// Create User Access Array
$USER_ACCESS = array_flip($access_levels);
/*This is Another Way to Define The Access Array
foreach($access_levels as $key => $value){
$USER_ACCESS[$value] = $key;
}
//*/
// Start Defining the access. To create a new variable. EG: SPECIAL_MEMBER
foreach($USER_ACCESS as $key => $value){
$DEFINE_KEY = str_replace(" ","_", strtoupper($key));
$DEFINE_VALUE = $value;
define($DEFINE_KEY,$DEFINE_VALUE);
}
?>
$USER_ACCESS = array(); // Create User Access Array
// Create Access List Array
$access_levels = array("0" => "Guest",
"1" => "Member",
"2" => "Special Member",
"3" => "Global Moderator",
"4" => "Administrator");
// Insert Access List into the User Access Array
// Create User Access Array
$USER_ACCESS = array_flip($access_levels);
/*This is Another Way to Define The Access Array
foreach($access_levels as $key => $value){
$USER_ACCESS[$value] = $key;
}
//*/
// Start Defining the access. To create a new variable. EG: SPECIAL_MEMBER
foreach($USER_ACCESS as $key => $value){
$DEFINE_KEY = str_replace(" ","_", strtoupper($key));
$DEFINE_VALUE = $value;
define($DEFINE_KEY,$DEFINE_VALUE);
}
?>
You could do something like this;
CODE
if(UserAuthentication($USER_LOGGED_IN, GUEST)){
echo("This page can be publicly viewed.");
}
echo("This page can be publicly viewed.");
}
It wouldnt take much modifying to turn the hard-coded "$access_levels" array list into something taken from a database.
Sorry if its not really sounding like a tutorial, but...
1) Im tired
2) I dont usually write the tutorials, but the code for the tutorials.
Gimme pointers on makin this sound more tutorialish.
Hope this helps someone
