[PHP-DB] session and form
hiii all, i've posted this question some days back. but didnt find answer. so posting it again. in my phpscript, some users are allowed to del/modify contents of the database. for this they have been provided login name and password, after user loggs into the secure area, session starts. since here, user can modify/del contents of database, i need to use many forms. arrays have been used to store the checkbox, textbox values which user wants to modify. since these values are submitted thru forms in session, when browsers back button is pressed, it forces to press refresh button, to retrieve the values. and page loads only after pressing refresh button. can any one pls tell me why it happens? and how to pass variables thru form in session ?? smita _ MSN Photos is the easiest way to share and print your photos: http://photos.msn.com/support/worldwide.aspx -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP-DB] Pedigree question
Yes, there are. There is a pretty good php code, called HTML Tree which can make trees, dynamically. Regarding the coding itself...you can have a simple table that records who is ancestor of who. This is a solution. Another one, which is not so neat is to create a table with 5 columns...one per generation. Does this make sense?

[PHP-DB] a where clause question
Hi, I need a where clause in following situation: Say I want to query two tables: A and B. In table A there is field Afn, while in table B there ere 3 fields: Bfn1, Bfn2 and Bfn3. I want to compose a query, in which the where clause can do this: if A.Afn=1, then check Bfn1, if A.Afn=2, then check Bfn2, if A.Afn=3, then check Bfn3. So how I compose a where clause to do this?

[PHP-DB] DBF question: column names?
Hi there. I'm not familiar with DBF files, or the PHP dbase functions. I've found (very) few code snippets on the Web about DBF files...a class on PHP classes and a couple of other brief mentions elsewhere. I have a question: I was given a DBF file that I don't know the structure of. Is there any way to read the column names and find out what they are, or do I need to have someone send me a description of the table structure before I can work with their file? I assumed I could just read the structure, and then print the column names out or smething, but I can't seem to find any examples of that. -- Marc Antony Vose http://www.suzerain.com/ Imagination is more important than knowledge. -- Albert Einstein -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

RE: [PHP-DB] passing array to next page
Also, if you decide to use serialize() and unserialize() through the post variables (I'd recommend against using it in the query URL because some browsers have a limit as to how much data they can fit into it), you should consider encrypting it in some way or at least appending an encrypted CRC to it. This is to prevent a malicious user from modifying the contents of the array in a way that may be dangerous to PHP or to your code. Take a look at these functions: http://www.php.net/manual/sk/printwn/function.crc32.php Calculates a CRC http://ca.php.net/manual/en/ref.mcrypt.php Family of extensions that provide encryption capabilities (not available on Win32, I believe) -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP-DB] $_POST And $_REQUEST
>$_REQUEST is an associative array consisting of the contents of $_GET, >$_POST, $_COOKIE, and $_FILES Also, they are not function but arrays, as Hatem said. You can usa $_REQUEST as a "catch-all" that provides you with both what was passed to your page through the URL query ($_GET) and what was posted to the webserver through HTTP ($_POST). IMHO, it's always better to use the more specific arrays ($_GET or $_POST), because that makes your pages more accurate and, therefore, less open to possible attacks. -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
