 Week #9 TO-DO ASSIGNMENT: Write a script to enter urls using a form and save the unique urls in a cookie for the current browser session, and then display the urls that are saved using the same script as active hyperlinks opening in a target window. Write an administration script with the ability to modify and delete urls from the set cookies and protect access to this by using a script-based hard-coded password protection area. In the form portion where you modify the existing links be sure to prefill the input form with the existing url so it can more easily be modified.

Post this assignment here so that we can offer comment/critique for you, but also post a URL to the working copy of the script and the complete source code of the script in your post.

scriptname.php <-- script name

Good luck to you!

 ok, im changing hosts and thats why ive been a lil delayed with assignement 10

on my new host register_globals are off so i was updating all my scripts to work with that, but this one either needs something more or i just dont get what wrong. the code is basically the same, just added the following $trings to the beggining of each:


assignement9advanced.php

<? ob_start(); ?>
<html>
<head><title>URL memorizing form</title></head>
<body>
<?
global $PHP_self;
$SCRIPT_NAME = $_SERVER["SCRIPT_NAME"];
$admin = $_COOKIE["admin"];
$urls = $_COOKIE["urls"];
$username = $_POST["username"];
$password = $_POST["password"];
$added = $_POST["added"];
$adminaction = $_POST["adminaction"];
$action = $_POST["action"];
$name = "Quick";
$pass = "saver";

administrator9advanced.php
<? ob_start();
$action = $_REQUEST["action"]; ?>
<html>
<head><title><? if($action) { print("$action Url"); } else { print("URL memorizing form - Administrator mode"); } ?></title></head>
<body>
<?
$urls = $_COOKIE["urls"];
$urlaction = $_POST["urlaction"];
$dellink = "http://quicksaver.beigetower.org/php_assignements/administrator9advanced.php?action=Delete&url=";
$modlink = "http://quicksaver.beigetower.org/php_assignements/administrator9advanced.php?action=Modify&url=";
$adminurls = explode("§", $urls);
$howmanyurls = count($adminurls);

the rest is exactly the same. I dunno what im missing, if i enter the admin mode it doesnt show the urls on the cookie! help?!
its here

 Alright guys, this lesson got me mroe than any before, because it seriously calls for remembering everything you were taught, plus going out and doing some PHP learning on your own. It's a much more creative and thus individual assignment.

Some things about my script that you may want to know. First off, IT DOES WORK WITH PHP5. I don't think any of the other examples do. Second, my script limita the user to 15 favorites, but you can easily change that by going through all the loops and changing "$n < 15" to whatever number you want. Finally, there are two pages only because when you set a cookie, the page must refresh before you can see it. If you refresh the page though, it remembers not only the cookie, but also you submitting the url form. the resulting page will have the new link displayed, but it will also have an ERROR message saying you altready have that link. To avoid getting this spam error message, a second page is used called "refresher" in which the only code is a header leading to the HTTP_REFERER... in other words, right back where you started except without the error.

Anyway, now you know how it works, but now also you can how it works :) This took me DAYS to perfect, so I hope you guys like it!!

 Gixboy - you did a really nice job here. I must admit that I was surprised to see the qualiy of your work. Keep at it.

BTW, you are welcome back in the chatroom as long as you can not interupt and be rude to those who are trying to help you.

 thanks, but I was being naive when I said I "perfected" it. The eregi() web url function has a ? after the ^(http://) that should not be there. The way it is now, you can add something like "gixboy.com" instead of "http://gixboy.com" and that will ultimately make the link lead to http://gixboy.com/gixboy.com which, of course, doesn't exist.

Also, if you put that code into a browser, you'll notice that the first time you use the script, nothing will happen - you must use it again before it wakes up and realizes that it should be doing something. That can easily be fixed by just moving the if(!$_COOKIE['urls']) conditional ahead of if($_POST['action']=="true") conditional.

You need to make those two changes for the code to work 100% properly. I did not realize either of those two because, respectively, I tested the false url by randomly typing in letters or leaving it blank, and I had been testing so much that the cookie was set, so I never retested the first time. It wasn't until I uploaded it onto my domain and tried to access it from another desktop that I realized what was happening.

Besides those two little things, there are things that can be done to make the code shorter, that, after writing the thing for days, I was too lazy to go back and do. But it still works nonetheless.

Thanks TD for your enthusiasm in the quality of my script, but for now I'm gonna fly solo when it comes to programming. I'll use the script school when I need to, and I'll post the assignments here like I have been, but I won't be asking questions in the chat anymore. As we saw today, at the point that I'm getting to, it's hard to phrase both a question and an answer in a way that both parties can understand. Between the time it takes to decipher one another's thoughts and to argue, I probably could have figured the problem out on my own by then.

 As far as 'nothing happening' goes, you may want to look back to week #8, where headers and redirection were covered.


<?php
if($this){
header("Location: $PHP_SELF");
}
?>




But I'm sure you would have "figured that on your own"...
