Subject: [PHP] Introduction and questions...
Hi Everyone, I'm very new to php and to this list. I'm hoping to be
able to suck up as much knowledge from this list as I possibly can
and be able to help and contribute in the future.
But until that time, I'm in need of some help.
I'm trying to write an image gallery script(Or program/application?)
for displaying images on a web page. That part of it is working just
fine, what I want to add though is the ability for people who use
this script to be able to copy/paste a link to insert the HTML into
their page/weblog.
In other words... How do I get it to display the text: img
src=myserver.com/path/to/picture height=reasonable size instead
of actually displaying the picture?

Check htmlentities on www.php.net/htmlentities.
It converts and other characters to their correspondent html entities
(http://msdn.microsoft.com/library/default.asp?url=/workshop/author/dhtml/re
ference/charsets/charset2.asp )
=
Here is a copy/paste from the
code I've been using:
if ($i = '5')// column count
(designed for 5 columns wide - change the 5 for however many wanted)
{
$i = $i + '1';
echo 'td align=left width=115
height=100
a href='.$filename.'img src='.
$filename.' height=60 border=0 //abr /
font size=1 face=tahoma'.
$filename.'br /'.filesize($filename).' bytes. BR / link info:
img src=quot;http://www.raoset.com/media/images/texas/images/'.
$filename.'quot; height=50% /font
/td
I have tried another more robust script but this is the one I'm
currently working with. I'm usually a quick learner but right now I'm
just lost, and I can't see the trees through the forest.I'm pretty
sure I'm using php4.*, If someone can tell me where exactly to find
that I would be more then happy to tell you the EXACT version I'm
using. :) I'm not real good on the command line YET... It's another
one of my many projects filed under CRITICAL Ahhh... The joys of a
small business and wearing many many hats :)
=
Check www.php.net/phpinfo.
1. Create a php file onn your webserver named phpinfo.php.
2. Insert the following code:
?php
phpinfo();
?
3. Call the script from your browser.
=
Anyway... Long enough post for my question I think, if you need more
info let me know, and thanks in advance for any help even if it's
just a RTFM... Just please include TFM ;)

RE: [PHP] Hidding HTML Input Elements values approach
-Mensagem original- De: David Dorward So the value attribute contains an encrypted representation of the country name ... which is transmitted in clear text right next to it? If you want encryption, why not just use SSL? The value attribute contains an encrypted value of a row id in the database table for countries. How would I know which country the user has selected if I don't know its row id to insert on a members table (either plain, masked or encrypted)? name ... which is transmitted in clear text right next to it? What is posted is the value attribute of the option elements not the country text (do a print_r($_POST)). Suppose you are on a Private Area on a website after login and you might have links such as: a href=page.php?changeprefsPreferences/a a href=page.php?op=3Change Password/a a href=site/changeemailChange E-mail/a In my approach these links would be like: a href=page.php?ad6467ae6757Preferences/a a href=page.php?op=97874bd86a4a5Change Password/a a href=site/97874bd86a4a5Change E-mail/a - for this you need ht access on apache -I think- -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Hidding HTML Input Elements values approach
Greetings.
I would like some feedback on this approach for encrypting HTML input
element values such as Checkbox, Radio, Select, Hidden, etc, and Javascript
code related to those elements.
The procedure is when a user first arrives at the site a session structure
is created and in it I create a random key string to use on encryption
functions for every page requested by that specific user.
So, for example a typical country select box, its option values are
encrypted with the previous created key on page request and decrypted (after
form submission f.ex.) on the validation code:
form
input type=hidden name=op value=aba87bdbs897a87e9986ab76
select name=country
option value=aba7b6a76d6eb76bf98ab986ab76Country Name/option
/select
/form
function ExampleValidation(){
// ...
$country_id = isset($_POST['country']) ?
MyDecryptFunction($_POST['country']) : 0 ;
// etc...
}
I also use this approach to encrypt values in Querystrings such as ids,
operations, form steps, etc.
So far I haven't found any holes on this approach (except when someone
gets access to the hosting account :] ) so I would like some feedback and/or
ideas and/or other approaches.
Thanks in advance.
Apologies for my bad English.
Pedro.

RE: [PHP] Hidding HTML Input Elements values approach
-Mensagem original- De: jblanchard I don't see any problem with the approach, but I would ask why... Because if I write original ids or values matching those on database (or other data source) they can easily be changed on client side, that is the main purpose. Another purpose is to easily allow forward/back on a form with several steps without showing the 'internal step' and avoid the The page you requested has expired; Increased security (I think, that's why I posted) because the encryption key is different for every user/visit to the site (not page). The project in question has several long forms and different types of payments (sms, unique cc number, etc). -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] php versions between os/platform
Greetings! I am building a website using PHP 5.1.2 and MySQL 5.0.18 and I am using windows xp with IIS. All the hosting companies I have contacted are using php 4.x.x and mysql 4.x.x or 3.x.x, on linux I suppose. Are php versions the same for every os/platform?
