Hello! I've got exactly what I've wanted in my previous topic so I have decided to make a new topic for some help.

And a database like this;

Code: [Select]
<?php
function generate_forums($parent)
{
$has_childs = false;

global $forums_array;        

foreach($forums_array as $key => $value)        
{
if ($value['parent'] == $parent)
{
if ($has_childs === true)
{
$has_childs = false;
}
echo '<a href="/category/' . $value['title'] . '/">' . $value['title'] . '</a><br>' . $value['description'] . '';        
generate_forums($key);        
echo '<br>';
}
} 
}
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.

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, 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!  

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,

So i'm having a little trouble trying to simplify some code I already have.

Code: [Select]
$result = mysql_query("SELECT images, cat_id FROM image_cat");

while ($row=mysql_fetch_array($result))
{
$cat_id=$row['cat_id'];
echo $cat_id;
$imgresult = mysql_query("SELECT * FROM images WHERE cat_id='".$cat_id."'");
while ($col=mysql_fetch_array($imgresult))
{
echo $col['img_id'];
}
}

Okay, so this works, however i'm sure I can bring it together under one query, though i'm truly stumped as to how?
I thought I could do a simple join:

Code: [Select]
$result = mysql_query("SELECT image_cat.cat_id, images.img_id WHERE image_cat.cat_id=images.image_cat");

This works, but repeats the image category on each loop. I could remove this via php if statements, but there must be a simpler/mysql solution.

If it doesn't make any sense I need to get

Img cat 1
-img 1
-img 2

img cat 2
-img 3
-img 4

etc etc

That join will give

img cat 1
-img 1
img cat 1
-img 2
img cat 2
-img 3

Hope that makes sense?? And any help would be amazing!
Thanks.

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.

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?? )

I have made a custom post type for products, and am using a custom taxonomy for the product categories. The thing that I am wondering about is that sometimes a product category is a parent, and sometimes a child, but sometimes both. For instance, if you have a top level category named shoes, then you might have a sub category named Nike. However, Nike also has shirts, so you could say that shoes and shirts were both subcategories of Nike. Do you know what I'm saying? It's like there is no real parent to child relationship, but they are both parents and both children of each other. How do you handle this type of situation?

Im struggling with how to filter items that have multiple categorises say if i wanted to search for a shoe that is good for walking and hiking in my database?

Shoe_id
Shoe name
color_id type_id

colors color_id color   type type_id type

My problem is what do i do in a situations like this? say a shoe is good for walking and running? aka type 1 and 2 

shoe id 1 shoe name nike color id 1 type id 1 and 2   

Hi,

I have been working on an eCommerce platform for the last few months. Its almost complete but I need to do one thing and thats to only display sub categories if products exist in them.

This is the site craftgo.me (development site),

and this is how the categories are produced for a category page. ie. http://www.craftgo.me/category.php?cat_id=96

Code: [Select]
if($_GET['cat_id']) {
$parents_id = $_GET['cat_id'];
$cat_num_rows_sql = "SELECT category_id, parent_id FROM mccategories WHERE parent_id = '$parents_id'";
$cat_num_rows_result = mysql_query($cat_num_rows_sql);
$cat_row_count = mysql_num_rows($cat_num_rows_result);

if($cat_row_count == '0'){
$current_cat_parent_sql = "SELECT parent_id FROM mccategories WHERE category_id = '$cat_id'";
$current_cat_parent_result = mysql_query($current_cat_parent_sql);
$cat_parent_row = mysql_fetch_array($current_cat_parent_result);
$parent_id = $cat_parent_row['parent_id'];
} else {
$parent_id = $_GET['cat_id'];
}
}



$catsql = "SELECT category_id, category_name FROM mccategories WHERE cat_showing = '0' AND parent_id = '$parent_id' ORDER BY category_name";
$catresult = mysql_query($catsql);
while($catrow = mysql_fetch_array($catresult)) {

$category_id = $catrow['category_id'];
$cat_name = $catrow['category_name'];

echo '<li><a href="category.php?cat_id=' . $category_id . '">' . $cat_name . '</a></li>';
}

In the mcproducts table the category id for each product is under 'product_category'


Im not even sure where to start to make this work, but if anyone could give me a pointer, that would be super.

Many thanks
Eoin

I have got a script which is able to create hierarchical categories infinitely and display them as items in a ul.

What I need now is to get these categories to appear in a hierarchical dropdown i.e. the user clicks a menu and the dropdown drops down, then the categories that don't have any children will simply be displayed whereas the categories that do have children will have an arrow pointing to the right and once hovered over all of their children will be displayed in a new menu with their children and so on a nd so forth. Very similar to the way the windows menu bar works except with more levels.

Basically I want it to function sort of like a spry menu bar except it can go down then across etc etc and any further categories and sub categories that are added in will be shown. Can anybody help me out with this or perhaps point me in the direction of a tutorial that helps to avhieve this effect.

Heres my code that creates them in an unordered list:--



<?php

$link = mysqli_connect('localhost','','');
mysqli_select_db($link,'mydb');

$query = mysqli_query($link,'SELECT * FROM nested_categories');
while ( $row = mysqli_fetch_assoc($query) ){        
$menu_array[$row['id']] = array('name' => $row['name'],'parent' => $row['parent_id']);
}

function generate_menu($parent){        
$has_childs = false;        

global $menu_array;        

foreach($menu_array as $key => $value){                
if ($value['parent'] == $parent){ 
                              
if ($has_childs === false){                                

$has_childs = true;                                
echo '<ul id="categories">';                        
}                        

echo '<li>'. $value['name'];                        
generate_menu($key);                        

echo '</li>';                
}        
}        
if ($has_childs === true) echo '</ul>';
}

generate_menu(0);

?>

I am a new guy here and don,t have much knowledge of PHP. My problem is complex but let me explain it in simple lines.
I have two different codes , 1) This code takes form entries 'website','caption' and 'name' and stores it into the Table named as 'user_info' into mysql database. This page is saved as index.php

2) This code can add add new category as a root or a child of existing category with update(edit & delete) option.This page is saved as categories.php

Both codes are working(except upload function),but what i want to do is to combine the both forms (Items and category) into one page so that a user can add :

webite :Its any URL
caption: Description of website
name: name of the person
Add category:choosing existing category
Add new category:If not exist add new category

Tell me how can i combine both codes so that my item entries display under their categories????

1) code for items -stores in Table 'user_info'
