PHP - Category Forum System

Hope I am in the right area.  I am working on a project which is sort of a business directory.  I have a category table, a sub-category table then the actual account table.  So a user clicks on the category, then selects the sub-category to view information of accounts in that category, and then be able to click to see the full profile.  Here's where I am getting stuck.  A user may be listed in more than one sub.  As an example, let's say a parent is Cars, then subs might be New, Used, Parts, etc.  Now a particular user might be listed under all three subs.  How can I link them?  I have my cat/sub linked via parent/child id's.  However, how can I get the user to be linked to multiple subs?  Would I need to create a separate table to do similar to parent/child of the categories?  If so, then how would I insert the multiple id's into the table?  I assume at this point that I would use drop downs for the subs.  I am having a real hard time wrapping my head around this so any help is greatly appreciated.

An array of "categories" is given:

    $categories = array(
        array("id" => 1, "title" => "Pants", "children" => array(
            array("id" => 2,
                "title" => "Boots",
                "children" => array(
                    array("id" => 3, "title" => "Leather"),
                    array("id" => 4, "title" => "Textile"),
                ),
            ),
            array("id" => 5, "title" => "Sneakers"),
        ),
        ),
        array(
            "id" => 6,
            "title" => "Sort",
            "children" => array(
                array(
                    "id" => 7,
                    "title" => "Balls",
                ),
            ),
        ),
    );

I need to write a function searchCategory ($categories, $id) that returns the name of the category by the category ID.

Help me please.

Hi Guys (& Ladies of course) 

I'm having a problem trying to add post category to the H1 title, I have managed to butcher my theme so that the single post now removes the H1 from the title in the header & instead adds it to the post title.

But what I'd like to do now is keep the H1 blog title on all pages including home page, but I'd like to ammend the title with the addition of the post category, as follows;

currently shows "Top Rated Gadgets" on all pages.

would like it to show "Top Rated (category name)" when viewing a single post.

So if the category of the post was Asus Laptops it would show "Top Rated Asus Laptops" instead of the usual "Top Rated Gadgets"

The closest I have got to it so far is with
Code: [Select]
<?php the_category(', '); ?> but this returns a hyperlink ! Is there any method I can use that will simply return the category name as plain text..?

Any help would be much appreciated 

Thanks

I have created a form which allows people to add data to a database.  However, I want to replicate the form across several pages and give each page a category.

For example, if I have a website based on sport.  I have a page which enters information into the baseball category, a page which enters information into the ice hockey category, a page which enters information into the soccer category etc.

Can someone advise how I would do this?

Categories table:
id catname

Post Table:
id postbody posttile date  catid

so i am getting posts with catid for related posts like

http://localhost/site/index.php?action=category&cat=1

so where $_GET['cat'] is 1 it display posts from that category 1, now what i need is when i post a new post i hv choice to assign multiple categories to one post, so a post could be in cat1 and in cat2 as well . please any idea how can i do that? i was thinking to make a new rows in posts table for each category and set it to 0 or 1 , and when  i submit new post it will set 1 to those categories which i select upon writing post. but if i have like 20 categories i need to add more 20 rows in posts table.

is there any other better way i can accomplish this?
Thanks for help

Hello everyone,

I am currently working on the script taken from www.phpwebcommerce.com I am only a beginner and have been using it in a little project for an online game just to help my mates be able to trade items and such.

I have managed to get almost everything sorted apart from one thing. The function which gets the categories for a drop down select box:

Code: [Select]
/*
    Generate combo box options containing the categories we have.
    if $catId is set then that category is selected
*/
function buildCategoryOptions($catId = 0)
{
    $sql = "SELECT cat_id, cat_parent_id, cat_name
            FROM tbl_category
            ORDER BY cat_id";
    $result = dbQuery($sql) or die('Cannot get Product. ' . mysql_error());
   
    $categories = array();
    while($row = dbFetchArray($result)) {
        list($id, $parentId, $name) = $row;
       
        if ($parentId == 0) {
            // we create a new array for each top level categories
            $categories[$id] = array('name' => $name, 'children' => array());
        } else {
            // the child categories are put int the parent category's array
            $categories[$parentId]['children'][] = array('id' => $id, 'name' => $name);   
        }
    }   
   
    // build combo box options
    $list = '';
    foreach ($categories as $key => $value) {
        $name     = $value['name'];
        $children = $value['children'];
       
        $list .= "<optgroup label=\"$name\">";
       
        foreach ($children as $child) {
            $list .= "<option value=\"{$child['id']}\"";
            if ($child['id'] == $catId) {
                $list.= " selected";
            }
           
            $list .= ">{$child['name']}</option>\r\n";
        }
       
        $list .= "</optgroup>";
    }
   
    return $list;
}

Basically the problem is that it only creates a category list of two levels e.g.

Parent

    Child

and I wish to be able to have more sub categories e.g.

Parent

    Child

Is there anyway of adapting this code so it can do something like that? Many thanks for any help.

I'm not sure why but I copied the correct syntax from the wp codex page for it to display the date and title which it displays the titles for the categories however it only displays the date for the headlines category and don't know why. Any answers?

Hi, I have been working on a directory/cms script (first large script to build from scratch).

I am stuck on a small part of it where is shows users a list of the listings they have put in the directory.

Below is the code that generates the table that shows the list of listings which is pulled from the 'listings' table in my database.

Code: [Select]
<?php 
### List of listings user has posted ###
if(isset($_SESSION['userlogged'])) {
$user_id = $_SESSION['userlogged'];

$sqlCommand = "SELECT listing_id, cat_id, listing_title, listing_date, showing FROM listings WHERE showing='0' AND user_id='$user_id' ORDER BY listing_id ASC"; 
$query = mysql_query($sqlCommand,$con) or die (mysql_error()); 

$ListingDisplay = '';
while ($row = mysql_fetch_array($query)) { 
    $listing_id = $row["listing_id"];
$cat_id = $row['cat_id'];

if ($cat_id == '1') { 
$cat_name = "Carpenters";
}
if ($cat_id == '2') {
$cat_name = "Stone Masons";
}
if ($cat_id == '3') {
$cat_name = "Plumbers";
}
if ($cat_id == '4') {
$cat_name = "Landscapers";
}

$listing_title = $row["listing_title"];
$listing_date = $row["listing_date"];

$ListingDisplay .= '
<tr class="listingaccount">
<td><a href="edit_listing.php?lid=' . $listing_id . '">' . $listing_id . '</a></td>
<td>' . $cat_name . '</td>
<td>' . $listing_title . '</td>
<td>' . $listing_date . '</td>
<td><a class="hoverBtn" href="edit_listing.php?lid=' . $listing_id . '"><img src="images/btnedit.png" border="0"></a></td>
<td><a class="hoverBtn" href="remove_listing.php?lid=' . $listing_id . '"><img src="images/btndelete.png" border="0"></a></td>
</tr>';

} 
mysql_free_result($query); 

?>

<table width="680" border="0" align="right" cellpadding="0" cellspacing="0">
  <tr>
    <td colspan="2"><h2>My Listings</h2></td>
  </tr>
  <tr>
    <td>&nbsp;</td>
    <td>&nbsp;</td>
  </tr>
  <tr>
    <td><a href="account_add_listing.php">Add New Listing</a></td>
    <td>&nbsp;</td>
  </tr>
  <tr>
    <td>&nbsp;</td>
    <td>&nbsp;</td>
  </tr>
  <tr>
    <td colspan="2" valign="top">
   
   
<table width="100%" border="0" cellspacing="0" cellpadding="0">
  <tr>
    <td>Listing Code</td>
    <td>Category</td>
    <td>Title</td>
    <td>Date Entered</td>
    <td>&nbsp;</td>
  </tr>
 
    <?php echo $ListingDisplay; ?>
 
</table>
   
   
   
   </td>
  </tr>
</table>
<?php } ?>

That all works just fine, but I would like to be able to generate the categories automatically. I am thinking some sort of array, but im not quite sure how to go about it and was hoping maybe someone could give me a starting point I could work from.

My categories table is like this:

--------------------------
| cat_id | cat_name |
--------------------------

Many thanks
