MYSQL - Link To An Index Page
I'm working on a site which has several hundred articles stored in a MySQL database. On the bottom of the page are two links for the previous and next article. The site has been constructed in such a way that the database has fields containing the url of the previous and next pages (i.e. article.php?recordID=137) and these are pulled out of the DB in the form of links.
Rather than them having to add this to the DB every time a new article is added I'm trying to automagically do it in PHP. I've sorted the main part by taking the current article and either subtracting or adding it's ID by 1 to create the prev and next but I'm a bit stuck when it comes to the current (highest) article number. What I want it to do is link to an index page when there is no +1 (or -1 for the start).

Creating A Folder Index With Link
I'm trying to think of ways to create a folder index for a client. Basically they want to upload PDF's to a folder and have the PHP script index the folder for a file list with links to the files to be displayed in a browser. No navigation to other folders. Just a list of a specific folder with links to the files. This can be done with simple html and frames but they do not like the look and want more formating control. Any thoughts. I've seen some file manager scripts but that is more function than I need.

Check Whether The User Has Clicked On A Link - Undefined Index Error
if (!$_REQUEST['view']) { I placed that code in one of my files to check whether the user has clicked on a link that is supposed to direct it to view a blog item. If it is indeed untrue, then it shows a list of blog items, else it shows the blog with the id set by 'view' For some reason, the code works. But it gives me this undefined index error nonetheless.

Doesn't Like Index.php For Main Page
I've built a website and some of the pages are php pages (e.g. SomePage.php). It all works fine; both the html pages and the php pages come up and work just fine. I then made a change to the main index.html file and made it so that it's an index.php file instead, and it has some php code embedded in it, not much different than any of the other php pages on my site. But when I try to go to that index.php file, as the first file to bring up for the site, it fails to bring up the page but instead pops up an Open File dialog, asking if I want to Open or Save the index.php file. It's as if the server is not recognizing index.php as being a php file that needs the normal php pre-processing on the server side. I used to get similar prpoblems with the other php pages before I had my server properly set up with Apache and php and such. But all of that is indeed properly set up. The OTHER php pages come up OK. It's just the very first, index.php page, that doesn't come up correctly. What am I doing wrong?

Include() - Store The Text In The Index Page
I have a index.php page that has some text on it and I also have a edit_index page. From edit_index you can edit the text on the index page. But I don't want to store the information in a database or a text file but instead want to store the text in the index page. Since the index page is PHP i made a variable at the top named $index_content and that holds the current text. What I want to have happen is for me to be able to, from edit_index, is edit the variable with the new text. So when I hit submit on edit_index I want it to call up index.php and redefine the $index_content variabled stored in the page. But i don't know how to write to a page like that when it's not apart of the script being executed. I tried require(), but that didn't work, and I tried include() but that didn't work either. Is there some way to do this that i'm not aware of?

Blank Page Caused By Undefined Index
I upgraded my php from 4.4.7 to 5.2.4 and now the entire website doesn't work. So I am trying to learn PHP and go through the site one error at a time. If you have a idea why the upgrade caused the site to fail that would be great. But in the meantime this is the problem i am stuck on. I get this error now when transferring to a page Notice - PHP Notice: Undefined index: REMOTE_ADDR in c:locationSession.php on line 45. That line has the following code. $GLOBALS["$SessionName"]=md5 (microtime() . $GLOBALS[REMOTE_ADDR"]); Like I said this code worked before the upgrade. Any idea what I can do to fix this problem?

Want My User To Have To Go Back To The Index Page As Soon As They Login.
I am having a little trouble intergrating a login/user management script with my html pages. I have used the div tag put in my php in there and put the rest of the php where it is originally placed in the script. Here is my problem. I would like my user to stay on the same main page while the login part changes(goes to the members area). I have tried using i-frames but if there is a link in one, the main page does not change the i-frame does. Can this be solved with more php. I do not want my user to have to go back to the index page as soon as they login.

Php Page Will Not Process Link To Different Page

I am trying to use the following page (code listed here) to click on link, and display 1 of three pages.

Of course I copied this code from a php site tutorial somewhere. Page code below: <? if ($link == page2){ $page="files/page2.html"; } elseif($link == page3){ $page="files/page3.html"; } else{ $page="files/stuff.php"; } ?> <html> <head> <title> index.php </title> </head> <body bgcolor="#999999"> <table width="100%" cellpadding="0" cellspacing="0" border="0"> <tr> <td colspan="3"><h1>The Template (index.html)</h1></td> </tr> <tr> <td align="center" valign="top"><a href="index.php?link=index"> Page 1 </a></td> <td align="center" valign="top"><a href="index.php?link=page2"> Page 2 </a></td> <td align="center" valign="top"><a href="index.php?link=page3"> Page 3 </a></td> </tr> </table> <? include($page); ?> </body> </html>

Mysql Index Cardinality
I use a primary key in a table, insert a row, the cardinality is increased of 1 as well. I just tried to do that with an INDEX, and the cardinality is none unless I update it with analyze table for example I also tried with KEY (which is supposed to be an alias of index) and after the first insertion it updated the cardinality but not later on. 1/any explanation?is there a kind of random update from time to time? 2/ is that cardinality important to know? I read that big cardinality will ensure that the index is used for joins for example. Does MySQL check the "real" cardinality before querying?Or do I have to run an analyze table from time to time.

Also another problem is if the link doesn't contain the "=" sign to explode. Would that cause a problem?
