PHP - Help With Cms Structure And Ideas

I would like to be able to use this 

<img src="user/<?=$log_username. '/' . $main_image;?>" width="130" height="150" id="pic5"/>

to work within php and i am having a had time doing so  . Any ideas?  $log_username refers to the users specific username folder within the main users folder         html source code looks like this  ,but i need to reference this within  a PHP  code block not html

<img src="user/lexi/pic.png" width="130" height="150" id="pic5">

any ideas? thanks guys

Hi, I would like to generate a constant value that change from a website to website but have an identical value for a single website. For example 

$_SERVER['SERVER_ADDR']

doesn't change for a single website, but easy to guess. an other idea is 

realpath(dirname(__FILE__))

but this can change if the web application execute scripts located in sub directories of the main script that use this variable. So what other possibilities to get a constant value that doesn't change ?   Thank you.

ok so for the second issue of the night, has anyone used lightbox with images that are fetched from a database (mysql)??

i have the following but it opens at the bottom of the page and not in a lightbox...

echo '<a href="' . $row['image'] . '" rel="lightbox[roadtrip]"><img src="' . $row['image'] . '" width="100" alt=""></a>';

I'm just looking for some tips here. I am developing and selling an eccommerce shopping cart software package, and it has been received very well from the early adopters. There's just one small problem that prevents the software from being a truly out-of-the-box solution: the include path. Not all users have access to their php.ini file, and it's not always a php.ini file anyway. So this is something the installation is unable to set for the customer.

I'm using object-oriented PHP5 stuff, so I have a folder named "classes" with all the relevant stuff in there. I am unable to search for paths to the folder and hard-code those into source files (there are ajax calls and other fun stuff; hard to know the exact relation to the path).

I guess I could use set_include_path on the top of a bunch of files, but that is a small performance hit (and totally inelegant code). I could put the folder path in the database somewhere and query for it (and cache it so it's not a performance hit). None of this stuff seems good. The path seems like the best solution.

Unless you have better ideas....

Hi all,


I've been trying to improve the speed of my file download script and was wondering if anyone could advise me which of the following is more efficient (Don't worry its not the whole script, just one segment), in terms of speed and server load?

The way I have the segment currently:

//if file exists need to check authorision levels

//set access to no

$access = NULL;

//retrieve current user levels

$cpm = $_SESSION['MM_CPMGroup'];

$cpmh = $_SESSION['MM_CPMHGroup'];

$cm = $_SESSION['MM_CMGroup'];

$cj200 = $_SESSION['MM_CJ200Group'];

$cj = $_SESSION['MM_CJGroup'];

//set file category type & set access if allowed

if ($category == 'cpm') {

if ($cpm == '1') {

$access = 1;

if ($subcategory == 'techdata') {

$path = "files/techdata/cpm/";

}

elseif ($subcategory == 'msds') {

$path = "files/techdata/cpm/msds/";

}

elseif ($subcategory == 'symbols') {

$path = "files/symbols/cpm/";

}

else {

$path = "files/cpm/";

}

}

}

elseif ($category == 'cpmh') {

if ($cpmh == '1') {

$access = 1;

if ($subcategory == 'techdata') {

$path = "files/techdata/cpmh/";

}

elseif ($subcategory == 'msds') {

$path = "files/techdata/cpmh/msds/";

}

elseif ($subcategory == 'symbols') {

$path = "files/symbols/cpmh/";

}

else {

$path = "files/cpmh/";

}

}

}

elseif ($category == 'cm') {

if ($cm == '1') {

$access = 1;

if ($subcategory == 'techdata') {

$path = "files/techdata/cm/";

}

elseif ($subcategory == 'msds') {

$path = "files/techdata/cm/msds/";

}

elseif ($subcategory == 'symbols') {

$path = "files/symbols/cm/";

}

else {

$path = "files/cm/";

}

}

}

elseif ($category == 'cj200') {

if ($cj200 == '1') {

$access = 1;

if ($subcategory == 'techdata') {

$path = "files/techdata/cj200/";

}

elseif ($subcategory == 'msds') {

$path = "files/techdata/cj200/msds/";

}

elseif ($subcategory == 'symbols') {

$path = "files/symbols/cj200/";

}

else {

$path = "files/cj200/";

}

}

}

elseif ($category == 'cj') {

if ($cj == '1') {

$access = 1;

if ($subcategory == 'techdata') {

$path = "files/techdata/cj/";

}

elseif ($subcategory == 'msds') {

$path = "files/techdata/cj/msds/";

}

elseif ($subcategory == 'symbols') {

$path = "files/symbols/cj/";

}

else {

$path = "files/cj/";

}

}

}

if ($access < 1) {

// if user access not granted to file category return message

if($logging > 0){

$status = "Wrong Permissions";

include('logit.php');

}

if (! $_SESSION['PrevUrl']) {

//header("Location: ". $loginpage );

exit;

}

$redirect = $_SESSION['PrevUrl'];

header("Location: ". $redirect );

exit;

}

// if file exists and user access granted continue


Obviously the above is a lot of lines of code... So I have rewritten the above to look like:


//if file exists need to check authorision levels & retrieve current user levels

if ($category == 'cpm' && $_SESSION['MM_CPMGroup'] == '1') {

$access = 1;

} elseif ($category == 'cpmh' && $cpmh = $_SESSION['MM_CPMHGroup'] == '1') {

$access = 1;

} elseif ($category == 'cm' && $cm = $_SESSION['MM_CMGroup'] == '1') {

$access = 1;

} elseif ($category == 'cj200' && $_SESSION['MM_CJ200Group'] == '1') {

$access = 1;

} elseif ($category == 'cj' && $_SESSION['MM_CJGroup'] == '1') {

$access = 1;

} else {

$access = NULL;

}

if ($access == NULL) {

// if user access not granted to file category return message

$status = "Unauthorised";

include('logit.php');

header("Location: ".$_SESSION['PrevUrl']);

exit;

}

// if file exists and user access granted continue

switch($subcategory) {

case "techdata":$path="files/techdata/".$category."/".$filename; break;

case "msds":

$path="files/techdata/".$category."/msds/".$filename; break;

case "symbols":

$path="files/symbols/".$category."/".$filename; break;

default:

$path="files/".$category."/".$filename;

}


The second version is a lot shorter, but is it better? And could I shorten the if statement further so its more like:


//if file exists need to check authorision levels & retrieve current user levels

if (($category == 'cpm' && $_SESSION['MM_CPMGroup'] == '1') || ($category == 'cpmh' && $cpmh = $_SESSION['MM_CPMHGroup'] == '1') || ($category == 'cm' && $cm = $_SESSION['MM_CMGroup'] == '1') || ($category == 'cj200' && $_SESSION['MM_CJ200Group'] == '1') || ($category == 'cj' && $_SESSION['MM_CJGroup'] == '1') {

$access = 1;

} else {

$access = NULL;

}

if ($access == NULL) {

// if user access not granted to file category return message

$status = "Unauthorised";

include('logit.php');

header("Location: ".$_SESSION['PrevUrl']);

exit;

}

// if file exists and user access granted continue

switch($subcategory) {

case "techdata":$path="files/techdata/".$category."/".$filename; break;

case "msds":

$path="files/techdata/".$category."/msds/".$filename; break;

case "symbols":

$path="files/symbols/".$category."/".$filename; break;

default:

$path="files/".$category."/".$filename;

}


Any advice would be appreciated! Thanks!!

Hello Friends,

Iam in a little bit confused matter. Iam developing a website & it requires a user's banning system too so my question begin here that if i use user's IP to ban but they can easy access the website by using different proxy sites & almost ip address are dynamic not static.
Banning their email is waste thing because they can create a new email within 1min.

Anyone have experiences in these things ? How we can ban a user permanently from accessing the website ?

Hey guys I have a few pages where im echoing in one row at a time. Like for a email system. I want to color in every other row with CSS.
since im echoing in one row at a time i cant place a class on every other row saying which one is even or odd. wondering what are some ideas on how to do this.

One idea i had was maybe assign a number to each row then maybe a php math function to find if a number is odd or even? like to know if there is a correct or standard way to do this.
typed a small little example below

           $list3 = "SELECT message FROM pm WHERE id = '".($_SESSION['user_id'])."'";
           $list2 = mysql_query($list3) or trigger_error("SQL", E_USER_ERROR);
while ($list = mysql_fetch_assoc($list2)) { 
?>

<td class="odd"><?php echo $list['message']; ?></td> 

<?php } ?>

A picture to show what I mean by coloring every other row

Hi all,

I am working on php project and willing to use the "everything as a plugin" idea so alot of people can easily contribute.

I am wondering how I can make a php page that includes my plugins, without having to hardcode them(as in require_once, ...).
And afterwards it should be possible to execute a function on each of the enabled plugins.

Especially the "hardcode" part I am not sure on how to fix it.
As for executing a function for each plugin (so that will be a Class object), I wonder how I can make an object of each class from an interface and then execute a function without hardcoding the creation of all objects.

Any one ideas or experience with something like this?

Thanks in advance.

I'm currently working on a site that has about 4 separate panels on the page that all use an include to populate. Each include is interacting with the database and I'm thinking that it might congest the databse to have each panel connecting to the same data base and getting data when the page loads.

I was wondering if it would be good practice to take all the connections and functions and put them on a 5th include at the top of the page. This way the connections and functions would be available to each include.

Is this a good idea? Will it be a problem for the 4 includes to ask the php function list include for data? Is it better to just let each include contain only the code it needs?

Also, say I have 20 functions on the php include and one site page only needs to use 1 function. Would the php function include still loop thru and connect to the database for all 20 functions just because it is included or will it only use the bandwidth needed to execute the 1 function it is being asked to use?

Hope that's not over confusing.
Thanks!

Hello dear friends,

Let say we have

Code: [Select]
$to = "gigi";
then we have link like this

Code: [Select]
mysite.com/file.php?id=$1
We can change it to new form by add rule at .htaccess codes

Code: [Select]
RewriteRule -(.*)\.htm file.php?id=$1
So that the link be like this

Code: [Select]
mysite.com/$to-$id.htm

it will works , Now what if i want to make the link like this

Code: [Select]
mysite.com/$id/$to.htm
what will be the .htaccess code in this way ???

thanks

Hi. I am creating a database where a user can store up to 50 names of their family members. I have two table structures in mind and curious which one is the more efficient structure.


====================================================================================================

TABLE A:
userid-firstfamilymemberid-firstfamilymembername-secondfamilymemberid-secondfamilymembername        Note:(the columns would repeated until the fiftiethfamilymemberid and fiftiethfamilymembername for a total of 101 columns)     TABLE B:
userid-familymemberid-familymembername

======================================================================================================
which is more efficient... Table A which would have more columns but less rows or Table B which would have less rows but more columns.. also keep in mind that the fixed amount is 50 family members per a user. Thanks in advance.
