Different content based on category parent..

[lindsayanng]

I have not yet tried this, but I was curious how nested categories work on the product pages.. For instance, lets say I have a product in the tshirts parent category and the kids sub category... I want to create an if statement in the product_info.php that says something like this:

 

<?php

if ( basename($PHP_SELF) == FILENAME_DEFAULT ) {

if ( $cPath!='2' )

 

 

echo <img src="images/tshirt1.jpg"> <img src="images/tshirt2.jpg"> <img src="images/tshirt3.jpg">;

 

elseif ( $cPath!='3' )

 

echo <img src="images/longsleeve1.jpg"> <img src="images/longsleeve2.jpg"> <img src="images/longsleeve3.jpg">;

}

else

echo <img src="images/longsleeve1.jpg"> <img src="images/longsleeve2.jpg"> <img src="images/longsleeve3.jpg">;

 

?>

 

 

So the main concern is.. if the category displayed in the if statement is a parent category, and you are viewing any product in any sub category, will this work?

[lindsayanng]

At the moment.. I have this for testing..

 

  <?php 

if ( $cPath!='28' ){


echo' <img src="images/tshirt1.jpg"> <img src="images/tshirt2.jpg"> <img src="images/tshirt3.jpg">';

}else {

echo '<img src="images/longsleeve1.jpg"> <img src="images/longsleeve2.jpg"> <img src="images/longsleeve3.jpg">';

}
?>

 

What should happen is if you are on any product with the category cPath of 28, it should show the tshirt images, all other cats should show the longsleeve images.. This is not happening..

 

You can see here

The code

if ( basename($PHP_SELF) == FILENAME_DEFAULT ) {
if ( $cPath!='2' )

would never happen on the product_info page since it isn't the index.php page (FILENAME_DEFAULT) and doesn't use cPath. You will need to create a database call to get the category ID using the product ID for that page.

[lindsayanng]

Gahh that would explain it.. I forgot that I I can really use the cpath on the index page.. ok.. Since i'm not so great with mysql i will really have to spend some time with this..

 

SO i need to query the DB for the current category and then use that in the if/else statement??

[npn2531]

Actually if you put

echo $cPath;

on product_info.php it will display the category number, so in theory you would think you could do what Lindsay is proposing.

[lindsayanng]

Yea, apparently it works in mysterious ways :)

 

This is my exact code:

    <?php 

if ( $cPath!='28' ){


echo' <img src="images/tshirt1.jpg"> <img src="images/tshirt2.jpg"> <img src="images/tshirt3.jpg">';

}else {

echo '<img src="images/longsleeve1.jpg"> <img src="images/longsleeve2.jpg"> <img src="images/longsleeve3.jpg">';

}
?>

 

Does anyone see any typos or weirdness on my part.. Because if you can echo the cpath, you should be able to use it in an if statement (i would THINK)

[lindsayanng]

So any thoughts on this code here??

[Jack_mcs]

cPath is handled in application top and it may be safe to use it but I don't know that I would depend on it. Is it valid if someone directly links to the product page? I would prefer to call it explictly so there's no question about it. You can try

$cPath = tep_get_product_path($_GET['products_id']);

Your code for the image looks fine.

[lindsayanng]

Ok yes... I have a basic hack that would totally work..

 

 <?php 
switch ($current_category_id){
case "28":
echo' <img src="images/tshirt1.jpg" width="200px"> <img src="images/tshirt2.jpg" width="200px"> <img src="images/tshirt3.jpg" width="200px"><img src="images/productadd/hugmeup_2412-2.jpg" width="200px">';
	break;
		case "31":
echo' <img src="images/productadd/hugmeup_2386.jpg" width="200px"> <img src="images/productadd/hugmeup_2389-2.jpg" width="200px"> <img src="images/productadd/hugmeup_2422.jpg" width="200px"><img src="images/productadd/hugmeup_2477-2.jpg" width="200px">';
	break;
	}

?>

 

 

Where the case # is the cpath number.. works perfectly.. Now the next step is to move this out of the core code and have people enter it via an admin area.. but thats more work than I have time to do..

[Jack_mcs]

You should add a default section to that switch or your results may not be as planned.

watch out, $cPath == $current_category_id only for the toplevel categories,

it might be ok for your case, just make sure you are aware of the difference as they've been both in above code snippets

[burt]

$category_is_on = (isset($cPath_array) && (sizeof($cPath_array) > 1)) ? (int)$cPath_array[1] : (int)$current_category_id;

 

Do what you want with $category_is_on;

 

Should work on any page that affects the category menu; index, product_info, reviews

[burt]

Ahem ;)

 

I misread the question. Ignore previous post.

[burt]

Instead, try this:

 

$category_is_on = (isset($cPath_array) && (sizeof($cPath_array) > 1)) ? (int)$cPath_array[sizeof($cPath_array) - 2] : (int)$current_category_id ;

 

echo $category_is_on;

 

Untested, but you should be able to work something out from that.

[lindsayanng]

hey Burt.. I came back to revisit this.. I currently have my site set up like this..

 

PARENT CATEGORY (no prods. just for organizational purposes)

Subcat 1

Subcat 2

 

I FINALLY got it so that when you click on the parent category you see a link to the sub cat and beneath that you see all of the products in subcat 1 and subcat 2

 

This means that the path is different now.. If you go to a product that is in subcat1 from the parent cat listing, the switch statement does work (as expected and pointed out above)

 

So my question is.. how do you find out which category a product is in WITHOUT querying the cpath and instead actually getting the category..

[lindsayanng]

Oops.. heres my code as it is now

 

   <?php 
$category_is_on = (isset($cPath_array) && (sizeof($cPath_array) > 1)) ? (int)$cPath_array[1] : (int)$current_category_id;
switch ($category_is_on){
	//case "28":
case "29":
case "32":
	case "47":
		case "46":
		case "44":
		case "45":

echo' <img src="images/tshirt1.jpg" width="200px"> <img src="images/tshirt2.jpg" width="200px"> <img src="images/tshirt3.jpg" width="200px"><img src="images/productadd/hugmeup_2412-2.jpg" width="200px">';
	break;
		case "31":
		case "48":
		case "49":
echo' <img src="pagegraphics/dogsinclothes//hugmeup_2386-2.jpg" width="200px"> <img src="pagegraphics/dogsinclothes/products-258.jpg" width="200px"> <img src="pagegraphics/dogsinclothes/products-252.jpg" width="200px"><img src="pagegraphics/dogsinclothes/hugmeup_2481-2.jpg" width="200px">';
	break;
	}

?>

[lindsayanng]

Well I found a function that is pretty useful .. It gets the product's category not by the cpath but via the product ID (because it is associated with the category)

 

  $category_path =tep_get_product_path($product_info['products_id']);
