Authentication Scripts for a User Management Application (
Page 1 of 4 )
In this article we will continue to discuss the application-wide scripts that we started to talk about in the last article. These special scripts are used by all the scripts and pages of the application. We will continue to look at the func.inc script that has several useful functions defined in it. This article is the third part of a nine-part series.The func.inc script
This script is essentially an include file that contains helper functions, such as the one that uses regular expressions to check if a given email address is correctly formatted. The file contains at least four functions, which are listed below:
<?php
function isadmin($id){
//run query to check if this user is admin
$sql = "SELECT level FROM users WHERE uid='".$id."'";
$res = mysql_query($sql);
if($res){
$row= mysql_fetch_assoc($res);
if($row['level'] == 'admin'){
return TRUE;
}else{
return FALSE;
}
}
}
function isAuthed($uname){
if(isset($uname)){
return TRUE;
}else{
return FALSE;
}
}
function genpass()
{
//This function generates a 7 letter password
$chars = "1234567890abcdefGHIJKLMNOPQRSTUVWxyz
ABCDEFghijklmnopqrstuvwXYZ1234567890";
$thepass = '';
for($i=0;$i<7;$i++)
{
$thepass .= $chars{rand() % 39};
}
return $thepass;
}
function checkEmail($email){
if(eregi('^[[:alnum:]][a-z0-9_.-]*@[a-z0-9.-]+.[a-z]{2,8}$',$email)){
return TRUE;
}else{
return FALSE;
}
}
?>
