Sub-categories Tutorial

Hi,

I'm not sure what could be causing this. If you want us to look into this issue further, we can work on it through out consulting services.

Go to www.interactivetools.com/hire-us/ and fill out the form there.

Hope this helps.

Hello!
Great instructions... I'm sure this is User Error... ;)
I have it up - but the articles are not showing when clicked on so I'm obviously missing something.

Here's my page: http://www.aubriericheson.com/recipes.php

I stripped everything back out. Here's the stripped own version:
http://www.aubriericheson.com/recipes2.php

I appear to have 3 problems:

1) when I click on a category - it does not bring up the articles (recipes) in that category (recipe_categories). Right now I have one 1 in breakfast, dinner and snacks.

2) when I click on a recipe by title - I get a view urls error. I'm still a little new to this so a push in the right direction on that would help.

3) I would like the number of recipes within each category to appear after the name. For instance:
• Breakfast (10)
• Lunch (3)

Thanks so much for your help!!! Tina


And here's the code to the stripped own version:

<?php header('Content-type: text/html; charset=utf-8'); ?>
<?php


// load viewer library
$libraryPath = 'cmsAdmin/lib/viewer_functions.php';
$dirsToCheck = array('/home/content/a/u/b/aubrier/html/','','../','../../','../../../');
foreach ($dirsToCheck as $dir) { if (@include_once("$dir$libraryPath")) { break; }}
if (!function_exists('getRecords')) { die("Couldn't load viewer library, check filepath in sourcecode."); }

// load records

list($recipe_categoriesRecords, $selectedCategory) = getCategories(array(
'tableName' => 'recipe_categories',
));

list($recipesRecords, $recipesMetaData) = getRecords(array(
'tableName' => 'recipes',
));

?>

<h1>Browse Recipes by Category</h1>
<ul>
<li><a href="?">(View All)</a></li>
<?php foreach ($recipe_categoriesRecords as $categoryRecord): ?>
<?php echo $categoryRecord['_listItemStart'] ?>

<?php if ($categoryRecord['_isSelected']): ?><b><?php endif ?>
<a href="?category=<?php echo $categoryRecord['num'] ?>"><?php echo $categoryRecord['name'] ?></a>
<?php if ($categoryRecord['_isSelected']): ?></b><?php endif ?>

<?php echo $categoryRecord['_listItemEnd'] ?>
<?php endforeach ?>
</ul>

<!-- STEP2: Display Records (Paste this where you want your records to be listed) -->

<h1>Browse Recipes by Title</h1>
<?php foreach ($recipesRecords as $record): ?>

<a href="<?php echo $record['_link'] ?>"><?php echo $record['title'] ?></a><br/>

<?php endforeach ?>

<?php if (!$recipesRecords): ?>
No records were found!<br/><br/>
<?php endif ?>

<!-- /STEP2: Display Records -->

Hi csdesign,

1. You named your article's category field "recipe_categories" instead of "category". (Lucky guess!) You can either change the name of that field OR change this:

<a href="?category=<?php echo $categoryRecord['num'] ?>"><?php echo $categoryRecord['name'] ?></a>

...to this:

<a href="?recipe_categories=<?php echo $categoryRecord['num'] ?>"><?php echo $categoryRecord['name'] ?></a>

2. You'll need to create a Detail Page for your recipes. You can use the Code Generator to create one for you. After you have decided on a URL for it, go into the Section Editor, click the Viewer Urls tab, and enter the URL for your Detail Page.

3. First, add this code at the bottom of STEP 1 (but before the ?>):

$rows = mysql_query_fetch_all_array("SELECT c.num, COUNT(*) FROM {$TABLE_PREFIX}articles a JOIN {$TABLE_PREFIX}categories c ON a.category = c.num GROUP BY c.num");
$articleCountByCategoryNum = array_combine(array_pluck($rows, 0), array_pluck($rows, 1));

Note that you'll need to change the field name in red to match yours (recipe_categories.)

Next, add this (in red) to your display code:

<a href="?category=<?php echo $categoryRecord['num'] ?>"><?php echo $categoryRecord['name'] ?> (<?php echo $articleCountByCategoryNum[$categoryRecord['category']] ?>)</a>

Once again, you'll need to change both instances of "category" to "recipe_categories".

I hope this helps! Please let me know if you have any questions.

I'm getting close, but obviously, I'm still missing something. The Recipes page does come up with categories and all the right recipes list to the right of those categories, however, there are 2 errors with each category:

So on the main recipes page, it looks like it's trying to display the number of articles so when that works, that's perfect and each set of recipes is coming up - even with the errors.

when I click on a recipe in the right column, it's trying... I get the url with the title afterwards but get this error on a blank page:

MySQL Error: Table 'aubriedb.cms_articles' doesn't exist

example:
http://www.aubriericheson.com/recipeDetail.php?Cinnamon-Quinoa-Hot-Cereal-36

Okay, and I'm only throwing this easy on in there because I know it will take you a fraction of the time to tell me as it will for me to find it.

right now the ListPageFields for recipes.php is:

dragSortOrder, recipe_categories, title

If I want it to list first by recipe_categories, then drag order, then title (alphabetically, what's the correct working for A-Z DESC... or is that it?

thanks so much!! She has her content in - we're ready to launch on Sunday... hopefully. Thanks! Tina

Hi,

The first error being cause (recipe_category) looks like it's being caused because there is no field in the recipe_categories table called recipe_category.

The second error is caused because the variable $articleCountByCategoryNum is never actually created.

If you could give me some more information on exactly how you want this to work and the names of all of the fields in both recipe_categories and recipes, I can take a closer look at this issue.

Hope this helps.

Hi Jason,

Thanks for your post! What I would like to see happen is to have the list of categories in the left column with the number of articles (recipes) in each category following it:

example:

Breakfast (10)
Lunch (22)
Dinner (4)
etc....

When a user clicks on "breakfast", all of the breakfast recipes come up in the right column - and this works like that right now. The the user can click on the recipe title and that recipe will open in it's own page.

I didn't realize she would have so many recipes and she'll probably add a lot more. Do you have a suggestion for a way to organize the "view all" category button (which does nothing right now) or the "browse recipes by title" column.

I was thinking of this... but I don't know if it's doable.

On this page:
http://www.aubriericheson.com/recipes.php

Browse recipes by category would remain as described above.
Browse recipes by title, would be a list of the letters of the alphabet and when you click on "B" or any letter... all recipe titles starting with "B" would be listed below that. Is that possible?

Thanks so much for you help!! Tina
