I want to control the access in php website.
I have a solution right now with switch case.
<?php
$obj = $_GET['obj'];
switch ($obj)
{
case a:
include ('a.php');
break;
default:
include ('f.php');
}
?>
But when i have so many pages, it becomes difficult to manage them. Do you have better solutions?
Right now, i develop the application using php4. And i want to use php5. Do you have any suggestions when i develop it using php5?
Thanks
$obj = $_GET['obj'];
$validArray = array('a','b','c','d','e');
if (in_array($obj,$validArray)) {
include ($obj.'.php');
} else {
include ('f.php');
}
The more pages you have the harder it will be to control this.
Your best off using a framework of some sort, my personal preference is CodeIgniter.
why not just address a page itself?
first page
another page
I am not saying that this is the best solution, but years ago I used to have a website which used a database to manage the key, the page to be included, and some informations like additional css for instance.
So the code was something like:
<?php
$page = htmlspecialchars($_GET['page']);
$stuffs = $db->query('select include,css from pages where pageid = "' . $page . '" LIMIT 1');
?>
So when we needed to add a page, we just created a new field in the database. That let us close a part of the website too: we could have a "available = {0,1}" field, and if zero, display a static page saying that this page was under maintenance.

I am Working on making the menu for our content management software using php and we are having this small issue. Since we want everything to eventually be called in chunks, were breaking certain page items into chunks and loading them via functions through an included file. Since this is hard to explain, I will post some example code of what i mean below.
This is the file page.php (removed needless html code).
This is the page the user is on:
<?php
define("CURRENT_PAGE", "page.php");
include_once("data/main.inc.php");
?><html>
Content loads here.
<? desktopMenu(); ?>
</html>
Okay and here's the function for desktopMenu() from main.inc.php:
function desktopMenu() {
// Query to get the top level navigation links with no parents
$query = mysql_query("SELECT * FROM menu WHERE p_id = '0'");
if(mysql_num_rows($query) > 0) {
while($result = mysql_fetch_array($query)) {
extract($result);
if($isparent == "1") {
// Just check if they have children items
$sub_menu_query = mysql_query("SELECT * FROM menu WHERE p_id = '$id'");
if(mysql_num_rows($sub_menu_query) > 0) {
// CODE TO SHOW THE MENU ITEM AND ITS SUBS
}
} else {
// CODE TO SHOW REGULAR MENU ITEMS
// WANT TO INSERT class='active' if the CURRENT_PAGE is this value..
echo "<li><a href='#'>link</a></li>";
}
} else {
echo "<li><a href='javascript:void(0);'>Error Loading Menu</a></li>";
}
}
I am wondering how I can get the CURRENT_PAGE on the included script so I can load the class="active" onto the correct page. I am already using the following:
$config = include('config.inc.php');
$GLOBALS = $config;
on the top of main.inc.php, above this menu function so I could set global variables and include my $config['database'] variables for calling the SQL database within a function (doesn't work otherwise).
How can I check the current_page variable so I can set it active in the menu? I have tried a few different things but nothing is showing the way we expect it to. Thanks guy.
First of all I would recommend looking at MVC architecture when building your apps. I believe the use of GLOBALS is frowned upon.
To answer your question:
Since you are defining a constant define("CURRENT_PAGE", "page.php"); then this will be globally available within the scope of the function desktopMenu()
so you may use something like:
$className = (isset(CURRENT_PAGE) && CURRENT_PAGE=='xxxxx')?'class="active"':'';
echo "<li>link</li>";
xxxx string is most likely a field output from you database as the page name which will match the defined constant.
$className = (isset(CURRENT_PAGE) && CURRENT_PAGE==$result['page_name'])?'class="active"':'';
This is the basic form and you will most likely need additional conditions for the 'active' menu switch mapping to different pages.
I've tried to answer your question with an example although the structure you have used run the app is not the recommended way to develop.
I would look at the way modern frameworks are structured (Laravel, Zend, Symphony...) and utilise these.
I would also try and automate the page mapping (e.g. look at the URL and pull out the page from a rewrite which matches to the menu in your database)
best of luck
There are multiple options. Including static functions, global variables and passing the variable or object into the function.
The consensus for various reasons is to pass the variable into the function
$myVar = new Object\Or\Data();
function myFunction($myVar) {
//do stuff with $myVar
}
//then call the function
myFunction($myVar);
There are lots of answers to this question on stackOverflow, so have a deeper search. Here is an example
I found the solution to my problem and thought I would share here. I first set the call on the page.php to use desktopMenu(CURRENT_PAGE); and then on my main.inc.php I added this line
$thispage = CURRENT_PAGE;
function desktopMenu($thispage) {
//REST OF FUNCTION
}
And I set a table variable on each menu item called menu-group, so I can define the current menu group for a menu item and have the appropriate menu item highlighted when you're on that page or one of it's sub pages.
Thanks so much for the answers guys!
Just a small question for anyone out there that uses smarty. I am trying to pass PHP directly into my code, but when I do, the cached version cuts out the PHP and just prints it directly like so.
<div class="dashboard-card-content">
<?php
$con = mysqli_connect(Nice,Try,Fly,Guy);
$company_id = $_smarty_tpl->tpl_vars['auth']->value['user_id'];
$company_id = mysqli_query($con,"SELECT company_id FROM cscart_users WHERE user_id = $company_id")->fetch_object()->company_id;
$company_id = mysqli_query($con,"SELECT goal FROM cscart_companies WHERE company_id = $company_id")->fetch_object()->goal;
echo "Your current goal is: ".$company_id;
?>
This just prints all of it out on my webpage, so I tried using the following:
{Literal}
{Include_php}
{php}
And I just can't find a way to get my PHP code to go into my TPL how I want it. This is becoming really frustrating and all I want is for my cache files to leave the PHP code alone. Sorry if this is a dumb question but I have been researching this for a while. How do I implement SmartyBC so that I can still use PHP injections. And if using SmartyBC is a bad idea, can someone give me a dumbed down version of how to use a seperate PHP function page to set variables to show in the Template?
Smarty is a template engine for presentation logic only. You cannot put application logic inside a template. It was possible in older versions of Smarty but fortunately not anymore. Just execute those funcions in a php file and pass the result to the template.
And yes, you can use SmartyBC: http://www.smarty.net/docs/en/bc.tpl, but that's supposed to be used for compatibility with existing projects. It's a really bad idea and shouldn't be used for new projects.
Why do you want to use php in Smarty?
Put your logic into a class or function, and pass the data via the controller: Registry::get('view')->assign('smarty_variable', $data), and you are good to go.
You can create PHP function which gets necessary data from database. E.g.
function fn_get_company_goal($user_id)
{
$company_id = db_get_field("SELECT company_id FROM ?:users WHERE user_id = ?i, $user_id");
$goal = db_get_field("SELECT goal FROM ?:companies WHERE company_id = ?i, $company_id");
return $goal;
}
Put it to your addon. Then you can use it in the Smarty template in the following manner:
{$goal = $user_id|fn_get_company_goal}
I'm searching now for hours. I try to switch the store language after the login.
Given is:
The id of the Store I want to switch too.
The Event Observer is also done.
This is what I worked out the last hours
My Observer:
$customerId = Mage::getModel('customer/session')->getCustomer()->getId();
// Get the Store ID we want to switch too
$connection = Mage::getSingleton('core/resource')->getConnection('distributor_read');
$mainLanguage = $connection->fetchAll('SELECT...');
$storeId = $mainLanguage[0]["store_id"];
if (!$storeId == null) {
$storeCode = Mage::app()->getStore($storeId)->getCode();
// Here I have to switch by the store code
return;
}
Would be glad if someone could help me out.
At least I need a method to switch the language or storeview, but I don't find any working MagentoAPI methods.
to Set the store id programatically
In the index.php file, (in your language specific folder), add the following:-
$store_id = 'your_store_id_here';
$mageRunCode = 'store view code';
$mageRunType = 'store';
Mage::app()->setCurrentStore($store_id);
Mage::run($mageRunCode, $mageRunType);
I am suggesting you to create some temporary session variable from login action and read in index.php to set language pack and again unset it if your work has been done
Hope someone will find this information useful :)
I will tell you guys what I did for this case. I tried to get the Mage_Core_Controller_Response_Http class, completely in vain.
So I kept going on my research and I found a solution.
I used:
header('Location: '. Mage::app()->getStore()->getBaseUrl().'/customer/account?___store='.$storeCode);
There we go, my on login observer just set the language.
edit:
To set a new header could cause some problems, because if just any piece of html is already rendered you can not set a new header.
I worked sth. else out:
$url = Mage::getUrl('*/*');
$url .= "?___store=" . $storeCode;
$response = Mage::app()->getFrontController()->getResponse();
$response->setRedirect($url);
$response->sendResponse();
exit();
There is obviously still a problem, the exit shouldn't used in good software code, but a simple return does not work, it does not end or kill the observer action.
I still working on a solution to kill the observer in a right way. As I said the observer need to get killed to redirect the url.
I've searched far and wide and every CMS tutorial out there either doesn't explain this at all or gives you a huge chunk of code without explaining how it works. Even on stack overflow I can't find anything close to the answer, though I'd be okay with eating my words if someone could point me to the answer.
I am using PHP and mysql for this project.
I am building a CMS. Its extremely simple and I understand every concept I think I'll need except how to dynamically generate pages and page links. The way I want to do it is by having a database table that stores the name of a page and the main content of the page. That's all. Then I'd just call a script to pull the main content of a page into whatever page I happen to call. No big deal, right? Wrong.
Here's the problem. If I were to do this then I'd have to create a file for every page I want to create that calls the script that pulls the content from the correct database row. So I could add all sorts of page names and contents into the table but I don't know how to call them without manually creating new files each time I want to link to a new page.
Ideally there'd be a script that creates links to pages based on the page name row of the DB table as the pages are created. But how do you get those links with the ?=pageName at the end? If I just knew how that worked then I could figure the rest out.
UPDATE
The second answer really confirmed everything I thought I had to do but there is one catch. My plan now is to split up all the code into a series of functions and either include or require them in different templates that will be used to format the way pages are displayed. I need one look for the home page and one other design for the rest of the pages. I'm thinking that I'll have a function that says if ID is 0 then call this page template.php else call this other template file.php. But how do I pass the required variables to these new files? Do I just include the index.PHP page in them?
Bill your actually on the right track. Almost all web software today does extensive URL processing. Traditionally you would have php pages on your web root and then utilize the query string in the URL to refine the page's output. You have already arrived at why this might not be desired. So the popular alternative is the Front Controller design pattern. Basically we funnel every request to your index.php page and then route the request to internal pages or apps outside the web root. This can get complicated fast and everybody seems to implement this pattern in unique ways.
We can utilize this pattern without the routing by simply putting our app in the index page. The script below shows an example of what your trying to do in the simplest of ways. We basically have one page with our script. We can request the virtual pages by changing the id query string in our url. For example www.demo.net/?id=0 can be utilized as an index to your site. This should be the same as www.demo.net without the 'id' query. Just keep solving those problems one by one even if you don't know what the problem is. Once you start looking at other peoples code, then you can start seeing how other people solved the same problems you have.
The solution below will get you started, but then what do you do when you want an admin page? How do you authenticate the user? Do you duplicate alot of the code for yet another page? If your serious about your CMS then your going to want to implement some kind of framework underneath it. A framework to process the url, route to your application, load configuration files, and probably manage your database connection. Yea it gets complicated, but not if you solve each problem one at a time. Utilize classes or functions to share code to start. At the very least include a common "bootstrap" file at the top of your page to initialize common functionality such as a database connection. Read Stack Overflow just to keep up with whats going on. You can learn alot of terminology and probably find some answers to questions you didn't even know you wanted to ask.
Below assume we have a table with the following fields:
page_id
page_name
page_title
page_body
<?php
//<--------Move outside of web root-------------->
define('DB_HOST', 'localhost');
define('DB_USER', 'cms');
define('DB_PASS', 'changeme');
define('DB_DB', 'cms');
define('DB_TABLE', 'cms_pages');
//<---------------------------------------------->
//Display errors for development testing
ini_set('display_errors','On');
//Get the requested page id
if(isset($_GET['id']))
{
$id = $_GET['id'];
}
else
{
//Make page id '0' an index page to catch all
$id = 0;
}
//Establish a connection to MySQL
$conn = mysql_connect(DB_HOST,DB_USER,DB_PASS) or die(mysql_error());
//Select the database we will be querying
mysql_select_db(DB_DB, $conn) or die(mysql_error());
//Lets just grab the whole table
$sql = "SELECT * FROM ".DB_TABLE;
$resultset = mysql_query($sql, $conn) or die(mysql_error());
//The Select Query succeeded, but returned 0 result.
if (mysql_num_rows($resultset)==0)
{
echo "<pre>Add some Pages to my CMS</pre>";
exit;
}
//This is our target array we need to fill with arrays of pages
$result = array();
//Convert result into an array of associative arrays
while($row = mysql_fetch_assoc($resultset))
{
$result[] = $row;
}
//We now have all the information needed to build our app
//Page name - Short name for buttons, etc.
$name = "";
//Page title - The page content title
$title = "";
//Page body - The content you have stored in a table
$body = "";
//Page navigation - Array of formatted links
$nav = array();
//Process all pages in one pass
foreach($result as $row)
{
//Logic to match the requested page id
if($row['page_id'] == $id)
{
//Requested Page
$name = $row['page_name'];
$title = $row['page_title'];
$body = $row['page_body'];
$page = "<b>$name</b>";
}
else
{
//Not the requested page
$page = $row['page_name'];
}
//Build the navigation array preformatted with list items
$url = "./?id=" . $row['page_id'];
$nav[] = "<li>$page</li>";
}
?>
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">

foreach($nav as $item)

echo $item;
}
?>
</ul>
</div>
<div id="content"><?php echo $body;?></div>

I think you need to read about $_GET.
I also recommend a decent PHP book. Forget online tutorials; they are (for the most part) utterly useless.
I'm working on a page where I've listed some entries from a database. Although, because the width of the page is too small to fit more on it (I'm one of those people that wants it to look good on all resolutions), I'm basically only going to be able to fit one row of text on the main page.
So, I've thought of one simple idea - which is to link these database entries to a new page which would contain the information about an entry. The problem is that I actually don't know how to go about doing this. What I can't figure out is how I use the PHP code to link to a new page without using any new documents, but rather just gets information from the database onto a new page. This is probably really basic stuff, but I really can't figure this out. And my explanation was probably a bit complicated.
Here is an example of what I basically want to accomplish:
http://vgmdb.net/db/collection.php?do=browse<r=A&field=&perpage=30
They are not using new documents for every user, they are taking it from the database. Which is exactly what I want to do. Again, this is probably a really simple process, but I'm so new to SQL and PHP coding, so go easy on me, heh.
Thanks!
<?php
// if it is a user page requested
if ($_GET['page'] == 'user') {
if (isset($_GET['id']) && is_numeric($_GET['id'])) {
// db call to display user WHERE id = $_GET['id']
$t = mysql_fetch_assoc( SELECT_QUERY );
echo '<h1>' . $t['title'] . '</h1>';
echo '<p>' . $t['text'] . '</p>';
} else {
echo "There isn't such a user".
}
}
// normal page logic goes here
else {
// list entries with links to them
while ($t = mysql_fetch_assoc( SELECT_QUERY )) {
echo '<a href="/index.php?page=user&id='. $t['id'] .'">';
echo $t['title'] . '</a><br />';
}
}
?>
And your links should look like: /index.php?page=user&id=56
Note: You can place your whole user page logic into a new file, like user.php, and include it from the index.php, if it turns out that it it a user page request.
Nisto, it sounds like you have some PHP output issues to contend with first. But the link you included had some code in addition to just a query that allows it to be sorted alphabetically, etc.
This could help you accomplish that task:
www.datatables.net
In a nutshell, you use PHP to dynamically build a table in proper table format. Then you apply datatables via Jquery which will automatically style, sort, filter, and order the table according to the instructions you give it. That's how they get so much data into the screen and page it without reloading the page.
Good luck.
Are you referring to creating pagination links? E.g.:
If so, then try Pagination - what it is and how to do it for a good walkthrough of how to paginate database table rows using PHP.
