PHP - I Want To Show Categories In Header Instead Of Pages.

Hi,

my page is currently up at brewhas.org/transactions.php.  When I retrieve a set of results > the defined # per page (such as entering 'WI' for last name), I see the first page correctly, and see the links to next pages, but when I go to the next page there are no results displayed.  Same for p.3, etc.

So I've looked around enough to know that I need to pass a variable to the subsequent pages, either via a session variable or the URL.  I have 2 fields input on the form, as well as a limit and offset.  My questions are 1) do I need to pass all 4 and if so then should I use a session variable so the URL does not get too long, and 2) can anyone provide any help with setting session variables and including them to be passed?

I'm a newbie and have grabbed some code where I can but this is where i'm stuck.  thanks in advance.

MOD EDIT: [code] . . . [/code] tags added.

I have been going in circles about how to handle the issue that I have come up with and was hoping that someone could provide a different method. Basically I want to be able to create an infinite number of categories and allow them to be assigned to other categories then making them subcategories/sub sub categories if you will. My initial plan was to use a method I have used before by just saving the parent id of the subcategories and recursively going through the data. However, I am not to fond of this because of the inefficiency that it provides. I did some research and found that method is called the "Adjacency List". I also found another way to do it called "Nested Sets" which seems to be much more efficient but its a little harder to understand / maintain. I was hoping that someone here could offer alternatives to both of these methods that will allow me to keep the efficiency of "Nested Sets" but providing the ease of use / maintenance of the "Adjacency List".

Thanks in advance for any help.

I need to view this in dropdown menu using parent_list column

I have two tables, one called Categories and one called SubCategories. Each subcategory needs to be displayed under its parent category in a HTML table.

So I have this code, but I don't know how to list each Sub-Category under each Category in a HTML table.

<?php

require ('includes/initialize.php');

require 'classes/database.class.php';


$sql = "SELECT * FROM Categories, SubCategories WHERE Categories.ID = SubCategories.CatID";

$Result = $database->Query($sql);
 
$Data = $database->Fetch($Result);

?>

How can i make unlimited sub categories when i have this mysql fields: id, name, parent


Code: [Select]
$query = "SELECT * FROM cats";
$result = mysql_query($query);
while ($var = mysql_fetch_array($result)) {
  echo $var['name'];
  // now i need here some code for sub cats, but sub cat in subcat :(
}
Can someone help me?

Hi there, I have a piece of code that takes all posts with the category of 'model' and puts it on the models page. It then displays the post as a gallery using fancy box. The problem is I want all posts with the category of 'faces' to go on the faces page, but at the moment they are appearing on both pages. Here is the code I have. Any help will guarantee a donation as I am at my wits end trying to figure this out.

Code: [Select]
<?php
  global $post;

  $args = array(
    'numberposts'     => 8,
    'offset'          => 0,
    'category'        => 'models',
    'orderby'         => 'post_date',
    'order'           => 'DESC',
    'post_type'       => 'post',
    'post_status'     => 'publish' );

  $posts_array = get_posts( $args );
  $x = 1; // track model
  foreach( $posts_array as $post ) {
    setup_postdata($post); ?>
    <div id="model-thumb">
<?php
    $arg2 = array( 'post_type' => 'attachment', 'numberposts' => -1, 'order' => 'ASC', 'post_status' => null, 'post_parent' => $post->ID );
    $attachments = get_posts($arg2);
    if ($attachments) {
        $i = 1; // track images
        foreach ( $attachments as $attachment ) {
            $image_attributes = wp_get_attachment_image_src( $attachment->ID, 'full' );
            if ($i == 1) { // Get thumbnail info to display with second image
                $img1src = $image_attributes[0];
                $img1w = $image_attributes[1];
                $img1h = $image_attributes[2];
            } elseif ($i == 2) { // Display thumbnail with link to second image
?>
           <a class="allModels" rel="gallery<?php echo $x; ?>" href="<?php echo $image_attributes[0]; ?>" 
?><img src="<?php echo $img1src; ?>" width="<?php echo $img1w; ?>" height="<?php echo $img1h; ?>"/></a><br /><p><?php the_content();?></p></div>

<?php
            } else { // Other images

Hi guys

I need help writing a php script

I have a table 'categories'

with fields
'id' 'cat_name' 'parent_id'

the 'parent_id' is just an the id field..

I want to create a way to have unlimited sub categories

so I can have

categorie -> sub-categories
categories  -> sub-categories  -> sub-categories
categories -> products

If i have a list of categories like:
1. Billboards and advertisement section
  1(a)City Clock
    1(a)(i)Application fee  (has columns for approved price and proposed price)
    1(a)(ii)Advertisement Per year (has columns for approved price and proposed price)

  1(b)Billboards
    1(b)(i)Application fee for construction (has columns for approved price and proposed price)
    1(b)(ii)Charge per year without advertisement (has columns for approved price and proposed price)

  1(c)Something here.....
    1(c)(i) something here...(has columns for approved price and proposed price)
    1(c)(ii)something here...(has columns for approved price and proposed price)
    1(c)(iii) something here... (has columns for approved price and proposed price)
     e.t.c

THEN SOME CATEGORIES LOOK LIKE:category 2
2. Category name
  2(a)something here..(has columns for approved price and proposed price)
  2(b)something here..
    2(b)(i)something here..(has columns for approved price and proposed price)
    2(b)(ii)something here..(has columns for approved price and proposed price)



NOW: i have categories without sub categories and others with sub-sub categories , a main category doesn't does have a column for prices ( or lets just say other columns) , a sub category WITHOUT its sub category will have columns for prices, if a sub category has its sub category, then its subcategory should have columns for prices (this is where my problem is - how do i handle such a situation in php Mysql?? )

Hello, New to php&mysql here and need a little help.  I want to make category list with sub-categories and sub-sub-categories. The goal is when I load website I will see full list with master(root)categories . Then when I click some categories should load sub-category and if I click on sub-category should load sub-sub-category. Something like this:

Computers
     -> Motherboards
             -> Model 1
             -> Model 2
             -> etc.
Monitors
     -> Model 1
     -> Model 2

As you can see max level of sub-category will be 2+root.  Here is the perfect example what I want to do http://3docean.net/category   I don't understand(know) also how exactly will look my database table? How to store categories and sub-categories.   I don't want someone to write full code etc as I want to learn it but will be great if you guys can show me some good tutorial how to make it mostly database structure.   Thank you in advance!   p.s.  Sorry for my English!  

I have two tables subcat and category

structure
subcat
id_subcat|id_of_cat|subcat_name| and for
 main categories
ID_cat|cat_name|

now what I want to display them as
Main category
subcategory1
subcategory2
Main category2
subcategoryX
etc...

Here's the code I'm using but doesn't work,it doesn't display anything.

<?php
$query = "
SELECT ID_cat, id_subcat, subcat_name, cat_name 
  FROM subcat, category 
  WHERE ID_cat=id_subcat";
$result = mysql_query($sql);
 
$lastCat = null;
while($row = mysql_fetch_assoc($result)) {
  # Check if you need to print the category_name
  if($lastCat != $row['ID_cat']) {
# Not the same category as the last one!
# Print it and save the ID
$lastCat = $row['ID_cat'];
echo "<br />". $row['ID_cat'];
  }
 
  # Print the sub category
  echo "<br />". $row['subcat_name'];
}
?>

Hello, I am doing (well trying to do, anyway) a script where I need to follow a link, and through its source (file_get_contents) i need to to follow each "category" and into its "subcategory" (and sometimes even SUBsubcategory).
Lets say the first in the menu is called "Catfood", the second "Dogfood",
you click on "Catfood" and you get a submenu with for example "Whiskas", another one called "Purina Pro",
and you click "Whiskas" and you see a list of food called for example "Whiskas Junior Chicken" and "Whiskas Junior Fish".

then after i have followed "Whiskas", i need to go back and follow "Purina Pro".
then after "Purina Pro" i need to go back to "Dogfood" and do the same to its submenu + subsubmenu + food menu..

so yeah, thats pretty much it basically..
i have already used wget for windows to download the entire website to not put load on it all the time when trying stuff out..

i use RegEx to find categories, their products and price, and i got all that covered, it's just that the website isn't built very friendly for using Regex to tie lets say "Purina Pro" with being in the "Catfood" category, so i have to go through all categories and subcats to save the categories in maybe an array, and bind the subcategories to the main category ("Purina Pro" with "Catfood")

i hope this all doesn't sound too errr weird lol, any help is very much appreciated even enough to just get me started on my own! =)


****************** EDIT BELOW:

The menu looks a bit like this, though it's orinally not about cat or dogfood, they are just examples

Catfood
  - Whiskas
  - Purina Pro
Dogfood
  - Royal Canin
     - Puppy food
     - Grown
     - Senior
  - Bozita Robur

Hi all am haiving abit of a problem am trying to query 6 categories with 6 games each.With the code i done is only showing one cat with 6 games. How can i fix this ?. If you go to games-flash.co.uk you will see at the bottom of the home page that only one cat shows.   php code.

     <div class="catgames">

Hey all,

I have a relationship where a zone has many posts and a category has many zones but a zone can also have many categories. The zones are basically parts of a page, such as the main area and sidepanel stored in database as records with name fields such as 'panel' and 'main'. There's a serious flaw right now and I would like to know the best solution to address it. Right now I access the posts of a zone of a category like this:

Code: [Select]
$category->zone->get()->post->get();

The above ends up displaying all the posts in the database for any given category because when category is selected, it searches for the associating zones, and then selects all posts related to those zones, which is wrong. i want to select all posts of the zones associated with that particular category.

Current database:

Code: [Select]
posts
id zone_id

zones
id name

categories_zones
id zone_id category_id

categories
id

What should I do? Add a category_id column to the posts table and relate the post directly to the category as well as directly to the zones table so the post table would have two foreign keys: category_id and zone_id

Would this be the most effective thing to do given my requirements?

Thanks for response.

}
} 
}
generate_forums(0);
?>
The code works wonders. But it is hard to customize template wise.

$ID#1 $title = General
I would start off with <table>
I need to have the Categories that Parent = ( 0 ) to have a HTML <tr>
I also need the Categories with Parent = ( Value ) to have a HTML <td>
Then the tags would be closed off before $ID#2 $title = Gaming's template would start again.

I keep trying to scramble the coding around and can't seem to find that probably "simple" touch.
Thanks in Advanced.
