Dynamic Navigation Menu
I need to build a dynamic menu that will include certain links depending on what variables are in the URL. This is doable - right?
For example: catalog.php?product=widget&color=green
Menu would look like:
Green Widgets
Brand 1 Green Widget
Brand 2 Green Widget
Brand 3 Green Widget
etc.
Any help would be greatly appreciated!

Dynamic Navigation
I am trying to construct a dynamic navigation that expands when a visitor selects a sub-directory. The site has 6 sub-directories, plus the root. Is there a way to use a wildcard or something, to indicate all contents of a directory? For example (this does not work): <?if($_SERVER['PHP_SELF']=="/cars/*"){?> Anyone know of a solution? What about the root level, is there an option for that too?
Dynamic Menu CSS
I am trying for a long time now, to find a way of creating a dynamic drop down menu. I have the CSS part ready and working and also I have the first level of the menu working. the problem I have is how can I submit the id from the first level menu in order to make the query and create the second level and so on menu. I am trying to avoid Javascript but I can't see another way at the moment... What I want to achieve is to produce the menu on HOVER if that is not possible on click will be ok as well. Do any of you have an idea ? This is the code I have : ********************************************** <div id="menu"> <ul> <li><h2>Products</h2> <ul> <?php do { ?> <li><a href="?cat_id=<?php echo ($row_product_categories['prod_category_id']); ?>"title="<?php echo strtoupper($row_product_categories['prod_category_name']); ?>"><?php echo ucfirst($row_product_categories['prod_category_name']); ?></a></li> <?php } while ($row_product_categories = mysql_fetch_assoc($rs_product_categories)); ?> <ul> <?php do { ?> <li><a href="index.php?id=<?php echo ($row_products['prod_id']); ?>"title="<?php echo strtoupper($row_products['prod_name']); ?>"><?php echo ucfirst($row_products['prod_name']); ?></a></li> <?php } while ($row_products = mysql_fetch_assoc($rs_products)); ?> </ul> </li> </ul> </li> </ul> </div> **************************************************
Mysql Php Dynamic Menu
I am trying to write a script that will create dynamically a menu from MySQL database. The database table is a product categories table and it has the folowing filed: category_id, parent_category_id, category_name (some other fileds are there as well but these are enough to figure out the logic) I know that I have to store all the product_categories records in a temp array and then some how go through them and store the level of each record in the menu.... If you have done something like that I suppose you know what I mean and I would much appreciate to give me a hint here ... I had a look in the phpLayersMenu from sourceforge but it is really advanced OO code and I cannot understand the logic.... My target is to create a Tree menu with no pre - defined number of records...
Dynamic Select Menu
I am trying to populate a select menu with data from a mysql db. I get the select menu, but no content or errors. The two fields are id and websites. Here is the code:
Dynamic Drop Down Menu
I'm having difficulties displaying the MakeModelID for a row selected from a drop down menu I've populated from a table combining three attributes (Make, Model and Specification - for example Ford Transit LWB 350 HR). What I require is to capture in a variable, such as $MakeModelID, the ID for that record selected. Code:

Dynamic MySQL Nav Menu Sorting
I have this dynamic menu and I want to change the order of the menu items... I added a column in the database wich has an integer value for ordering the menuitems. But the only way is by hardcoding them into the database. I would like a way to sort them with drag-and-drop or with up/down arrows. Do you think that except PHP & MYsql I will need Javascript as well ? Any ideas how to do that ?
Dynamic Message Board Menu
Here's an issue I've spent the last 8 hours trying to get my head around, I'm pretty sure the answer is simple enough, but I just cannot work it out, any help would be much appreciated...even just a function name or something... I have a very simple message board setup. The browse menu will look end up like below, all dynamically fed from a database, which is currently setup as: [articleID] [articleDate] [articleText] 23 2007-07-18 Lorem ipsum dolor.... The 'articleDate' field is a DATE type, formatted yyyy-mm-dd. All posts should be sorted ascending, latest first. I want nothing to be hard coded, so there could be 2 posts in any month, or 200, or there could be no posts in any year. 2007 June - #1 - #2 August -#1 September -#1 -#2 2008 January -#1 . . . . . So on and so on. So far, I've toyed with array_unique(), as well as multi-dimensional arrays, but I'm really not sure if this is the right approach. I'd post code but I'm not sure there's any point, what I'm really looking to find out is the method to use, rather than code snippets, so if anyone has achieved this, how did you do it? I'm happy as to teach myself whatever I need to know, problem is I don't know what I need to know...
Dynamic Menu Bar In A Frame - Controlling Frames In Php?
I have been using in a lot of websites a script that creates a menu bar but avoids that the button to the current page can be clicked. I am rather satisfied with it (although suggestions for better ways of doing things are welcome, the script follows below FYI) No there is a a problem that for a new site (www.orkestbasic.nl/nieuw) the menu with the links has to be placed in a separate frame because the right part of the page must be scrollable. So the check wether a button has to be a link or not cannot be done anymore with checking PHP_SELF as I am used to do. I am thinking of making all the links to something like <a href = "main.php?content=songlist"> then main.php would be a frameset with something like <frame name = "content" src = "<?php echo "$content.php"?>"> In the left frame I could do a similar thing with a small modification to the createlink function (see below) I often use. But I would like to know if there are more elegant suggestions for it. Could not find really good tips on google. Thanks for any help FYI This is the function I have been using until now. function mvwMaakLink($omschrijving, $verwijzing, $separator = "", $aHrefClass = "", $noHrefClass = "") { $locatie = $_SERVER['PHP_SELF']; //link to the current page, no need for clicking on it //echo $locatie; if (strstr($locatie, $omschrijving)) { $beginTag = ""; $slotTag = ""; if ($noHrefClass != "") { $beginTag = "<span class = "$noHrefClass">"; $slotTag = "</span>"; } echo "$beginTag$verwijzing$slotTag"; } else { $beginTag = "<a "; if ($aHrefClass != "") { $beginTag .= "class = "$aHrefClass" "; } $beginTag .= "href = "$omschrijving">"; echo("$beginTag$verwijzing</a>$separator"); } }
Unexpected Order On Dynamic Select Menu
I've got a directory called 'potm' (picture of the month) that contains: 02.jpg 03.jpg 04.jpg I'm dynamically constructing an 'archive' select menu that contains all the available pics. For some reason the select menu reads: April February March I've tried to sort the array, but it made no difference. PHP Code:
[PEAR:QuickForm] Dynamically Change A Dropdown Menu According To Another Menu?
I've been using QuickForm for a few months now and I am now given a new challenge: I've got a search form with a dozen of dropdown menus, the first dropdown menu being "Brand". If you select either Brand A, B, C, D... Z, the second dropdown menu "Model" must be dynamically changed to model AA, AB, AC, AD..., according to the models manufactured by the brand selected in the first box. I've seen that done on quite a few sites, but never found if QuickForm had a quick & clean way of doing that.
Navigation Problem And PHP
Problem: I'm trying to get a navigation path/string similar to devshed or zdnet. ================================================= Example: "you are here: home / news / archives / article" With each in turn being a link and the last being the title. ================================================= I have a small file in the directory /news/archives/ that takes an include file and populates page from mySQL. A function is called (getNavPath) that looks to see where the file is and prints a navaigation structure back up the tree. A snippet of the code I've done so far: ================================================= <PRE> //passed in the doc title function getNavPath($navtitle) { $path = getenv("REQUEST_URI"); $dir=dirname($path); $dir_array=explode("/", $dir); // split the string by forward slash (directory delimiter) /* note: the array will now have an empty string as its first element because every file is at least under root ("/"). So we'll shift it by 1 to get rid of this empty string */ array_shift($dir_array); $arraylength=count($dir_array); //length of the array /* if the first element is set, i.e. we're not directly under root and can proceed*/ if(isset($dir_array[0])) { echo("<a href="/">home</a> / "); //prints home with a link back to home for($i=0;$i<$arraylength;$i++) { $dir_path.="$dir_array[$i]/"; echo("<a href="/$dir_path"."index.php">$dir_array[$i]</a> / "); } echo("$navtitle"); }//end if isset.. else { //print the title echo("$navtitle"); } }// end getNavPath </PRE> ================================================= The problem is that when I type the URL without the specific filename e.g. www.domain.com/news/archives/ it doesn't seem to work (although the index.php file is printed okay). Also if I do type in the full dir1/dir2/dir3/index.php, then dir3 will point to the current page, but I can sort this out. Can anyone help? Am I going about it the right way?

Using PHP In Navigation Crumb
I'm pretty new to the world of PHP and need a little assistance. I've got a static site at the moment, but I'd like to make it a little easier to maintain and update. One of the areas I think PHP will really help is with the navigation crumb. Rather than typing in all the information such as 'Home > Category > Article' ... what could I use? I'd like PHP to just insert the Home URL, followed by the category name and URL, follwed by the article title.
Controlling Navigation With PHP
I got a set of pages which must be navigated in a strict manner. Let's just say the pages are named A, B, C, and so on. I got no problem with forward navigation, but I want to disable the client browser's back button. More specifically, if the user is currently at page D, the back button doesn't bring the user to page C, but page A instead (assuming consecutive navigation, from A to B to C and so on). How can I achieve this with PHP, assuming both the server and the client are behind strict firewall (both referer and cookies disabled), and use of client-side javascript are avoided as much as possible (or even considered disabled as well, either by the firewall or the browser's setting)?

Dir Navigation With Php Ftp Functions
I'm having trouble navigating my directory structure using php's ftp functions (such as ftp_chdir and ftp_cdup.) I'm writing a program that allows a user to easily create robot.txt files and upload them to their server. They should be able to log in to their server using ftp and browse their directory structure, specifying which robots to allow into each directory. When the user logs into their server, they are presented with a list of directories displayed as links. Clicking a directories link will take them into that directory and will present them with the sub-directories contained in that directory. I have the program running at Each time is link is clicked, the page is refreshed and ftp_connect called, meaning that the user is logged back in to their root directory. I have a stack containing the directories that have been navigated, so that the program can direct the user to the drectory they intend to be in. This seems overly complicated. Is it possible to do what I am trying to do just using php's ftp functions, without storing a session variable containing all the directories that have been navigated? Is is possible to not have to re-login to the root directory every time a page that uses ftp functions is called? The solution I have seems to work well and handles symbolic links, but has the drawback that I can't navigate above the directory that the user originally logs into. It also just doesn't seem like the correct way to do this. I'm sure there is a simpler, more proper way. <?php include 'include.php' session_start(); //If $_POST variables are set then we are logging in for the first time and set $_SESSION variables accordingly if (isset($_POST['server'])) { $post = clean_post($_POST); $_SESSION['ftp_server'] = $post['server']; $_SESSION['ftp_username'] = $post['username']; $_SESSION['ftp_password'] = $post['password']; //Create a stack/array which holds the name of the directories we have traversed $_SESSION['directories'] = Array(); } //if we are not connected to a server then redirect to the login page if (!isset($_SESSION['ftp_server'])) { header("Location: login.php"); exit; } //If $_GET variables are set then we are actively navigating the directory structure if (isset($_GET['dir'])) { $get = clean_get($_GET); $ftp_dir = $get['dir']; } // set up a connection or die $conn_id = ftp_connect($_SESSION['ftp_server']) or die("Couldn't connect to " . $_SESSION['ftp_server'] . "<br>"); // try to login if (@ftp_login($conn_id, $_SESSION['ftp_username'], $_SESSION['ftp_password'])) { echo "Connected as " . $_SESSION['ftp_username'] . "@" . $_SESSION['ftp_server'] . "<br>"; $_SESSION['username'] = $_SESSION['ftp_username']; } else { echo "Couldn't connect as " . $_SESSION['ftp_username'] . "<br>"; } // turn passive mode on ftp_pasv($conn_id, true); //If we are navigating the directoty structure if (isset($ftp_dir)) { //if we are navigating to the parent directory pop the name of the current directory off the stack if($_GET['act'] == 'cdup') { array_pop($_SESSION['directories']); } //otherwise we are navigating to a child directory else { //grab the name of the current directory and push it on the $_SESSION['directories'] stack $pieces = explode("/", $ftp_dir); $relative_path_dir = array_pop($pieces); array_push($_SESSION['directories'], $relative_path_dir); } //Since the stateless nature of http forces us to always login to the root directory //we use the $_SESSION['directories'] stack/array to navigate to child directory we are trying to access foreach($_SESSION['directories'] as $rel_dir) { if (ftp_chdir($conn_id, $rel_dir)) { //do nothing for now } else { echo "Couldn't change directory "; } } //we are in the child directory, so display the path echo "Current directory is now: " . ftp_pwd($conn_id) . " "; } else { //we are in the root directory, so display the path echo "Current directory is now: " . ftp_pwd($conn_id) . " "; } function create_dir_tree() { global $conn_id; $files = ftp_nlist($conn_id, ""); //get files in directory if(is_array($files)) { //display a link to the parent directory echo "<br /><a href=index.php?&act=cdup&dir=" . ftp_pwd($conn_id) ..

Navigation In First Application
I've writing my first php application and it's killing me. I've been programming desktop stuff since the early ྌs but this is way different; php, html, css, and (god forbid) JaveScript all interacting. I figured out the session management (I think) and can log a user in and display a <table> with links <a> for the user to select the next action. What I would like is for the href to specify a php function and pass parameters to the function. Something like this would be cool but doesn't work. <a href="do_some_stuff($menu_data[menu].pid)">{$menu_data[menu].pname1}</a> I understand that the href thing can contain a URI or href="do_some_stuff.php", but how do you create a page where the user can select an option and have it call a function based on the selection? I'm using php5, smart, & Firebird.

Php Webcomic Navigation Script
i am wondering if someone can help me code something relatively simple for navigating through a linear series of php pages. my code is halfway done, and is basically functional, but i would like to add something to it. the code right now can find what page you are on, the next page, and the previous page. here is how it currently reads: <? //to get filename $p = $_SERVER["SCRIPT_NAME"]; $parts = Explode('/', $p); $p = $parts[count($parts) - 1]; //get filename $c = strtok($p,"."); //get number string $nc = $c+1; //next comic $pc = $c-1; //previous comic $ncf = "$nc.php"; $pcf = "$pc.php"; if (file_exists($ncf)) { echo "<a href="$ncf">go to the next page</a>"; } else { echo "<a href="0.php">go to the first page</a>"; } ?> <br /> <? if (file_exists($pcf)) { echo "<a href="$pcf">go to the previous page</a>"; } else { echo "<a href="2.php">go to the latest page</a>"; } ?> what i do if you are on the last page, a link to the first page would show, and this is not a problem since 0.php can be hardcoded. my problem, however, is in navigating the pages in decreasing order. is there any way to look at the current directory and get the token of only the php pages? i know that i can use the max() function to get the greatest one listed, but i do not know how to list the files to use the max() function.

Multilevel Site Navigation
my question is quite simple, but I have not found any sufficient answer even after spending several hours in google or reviewing this group. I am planning a website, which is using an index.php, which has a structure of the layout. In this script I am planning to have several include() -statements. One to generate the site navigation on the left margin. Another to generate content in the mainarea of the page. The content is stored in separate html-docs or php.-scripts, which are inserted into index-page. Variables, that are needed to pick the right content can be passed in the url. I will not use any database, because the content is quite static, but by using php I am anyway looking for easier maintenance and updating. My trouble is that I don't know how to generate a navigation that has three levels, like this: Item1 in first level ...Item1 in second level ....Item2 in second level .......Item1 in third level .......Item2 in third level .......Item3 in third level ....Item3 in second level Item2 in first level Item3 in first level Item4 in first level ....and so on.... When user enters the site, only main laevel's links are visible. When user clicks an item on the first level, the content is updated with the frontpage of this topic, but at the same time appropriate second level links are displayed. And so on. Of course I will use css to make links on different levels distinctive, so there must be a way to set different class-value in <a> tag in different levels.
Keyboard Navigation In Photoalbum
I've just started to learn PHP, so this may be a dumb quiestion, but I'll ask it anyway... Is it possible to create a photoalbum (or make use of such) with PHP, where I could navigete with my keyboard? When some picture from a gallery would be selected, could I navigate to next or previous picture by using for example buttons "n" and "p" from my keyboard? Is this possible to do with PHP or should I use JavaScript or such instead?

Automating Page Navigation And Control Transfer
Is there a system available to do the following: consider an app of a few pages: page1.php: form1----->page3.php form2----->page4.php page2.php: form3----->page3.php form4----->page4.php when I am at page3.php, I do not know whether I came there from page1->form1 or page2->form3. I can check for $_SERVER['HTTP_REFERER'] and get an answer. But this example is simple. Let us generailze that I want an app that keeps a track of all the pages the user requested, in the order that they were sent to him. Obviously, it can be written based on sessions. Is there already some popular open source application for this? Also, this brings me to a broader question of page navigation rules. In an app made of 20-50 pages/scripts, life will be hell if there is no systematic approach to transferring control between pages. Is there some kind of structure already made and readily available into which you just plug-in your pages by telling some rules ? E.g. the scheme is something like: $ListOfPages = array( 1=>"Main.php", 2=>"Edit.php", 3->"Add.php", .........., N->"Error.php"); $RuleSet = array( 1=>array("Main.php","Edit.php","allow_edit"), 2=>array("Main.php","Add.php","allow_add"), ................... 3=>array("Main.php","Error.php","my_error_handler") ); The RuleSet is a set of page transfer rules based on evaluation to true of the specified functions, i.e., allow_edit(), allow_add(), my_error_handler() etc. Obviously, form submission is the chief means of control transfer for PHP programs and the use of ?op=add_something in URL's(GET) and <input type=hidden name=op value=add_something> (POST) are a step towards making some kind of structure. So the grand code will look like: $MyGrandAppControllerObj = new GrandAppControllerObj(); $MyGrandAppControllerObj->setPages($ListOfPages); $MyGrandAppControllerObj->setRules($RuleSet); $MyGrandAppControllerObj->Run();
Shopping Cart Navigation And Back Button Browser
I am building a shopping cart where the user adds items to his shopping cart and shippes some to himself and others to someone else as a gift. I do the following thing, First let the user fillout his info and I ask him to check which items does he want to send to himself. Once he hit submit button I do the following. 1) I process which poduct does he want to ship to himself. Then I remove those products from the shopping cart. 2) Then if he has items in his shopping cart remaining I display address form and checkboxes asking user to check all items that he want to ship to this address. then I repeat step 2 until the user has no more items in his shopping cart. when he has no items I will display billing page. Here is my problem if user hits back button in the browser and then enters submit button I have not items in the shoppingcart since I removed them from his shopping cart the first time he processed his form. So how do I deal with back button in the browser. I have no idea how to it when I have multiple forms.

Counting External Link Clicks Whilst Maintaining Ease Of Navigation
I'm writing some php code to count the number of clicks that a link receives. Once the extra click has been counted it will redirect the user to the target webpage. However - it must also allow the user to click the back button once on her browser in order to return to the first page (as oposed to going back to the redirect page which will then instantly send the user to the website that I'm linking to). Sounds tricky to me but indeed.com have managed it. If you click on one of the jobs links on the following webpage you will be taken to a redirect page and then the target webpage. And... if you then use the back button in your browser you will go straight back to the search results, bypassing indeed's redirect page and so keeping navigation easy for the user: Code:
