Re: [chris] Sub-categories Tutorial

Hi Dan,

At line 38,

list($regionsRecords, $selectedCategory) = getRegions(array(

... should be:

list($regionsRecords, $selectedCategory) = getCategories(array(

And you'll need to match up your variable names in your body; this:

<?php foreach ($regionsRecords as $regionsRecord): ?>

... should be:

<?php foreach ($regionsRecords as $categoryRecord): ?>

Also, you're overwriting your $listingsRecords variable with that last getRecords call. You'll want to remove this:

list($listingsRecords, $listingsMetaData) = getRecords(array(
'tableName' => 'listings',
));

And finally, I just have to mention that you can get away with using a WHERE clause instead of beta_lookupRelatedFields (since you're only dealing with one record here.) If you wanted to, you could replace this:

beta_lookupRelatedFields(array(
'table' => 'listings',
'recordList' => &$listingsRecords,
'fieldList' => array( 'agent')
));
$listingsRecord = @$listingsRecords[0]; // get first record


// show error message if no matching record is found
if (!$listingsRecord) {
header("HTTP/1.0 404 Not Found");
print "Record not found!";
exit;
}

... with this:

$listingsRecord = @$listingsRecords[0]; // get first record

// show error message if no matching record is found
if (!$listingsRecord) {
header("HTTP/1.0 404 Not Found");
print "Record not found!";
exit;
}

list($listingAgentsRecords, ) = getRecords(array(
'tableName' => 'agents',
'where' => "num = '" . $listingsRecord['agent'] . "'",
));
$listingAgent = @$listingAgentsRecords[0];

Then you could use $listingAgent['my_agent_field'] instead of $listingsRecord['agent']['my_agent_field']. Go ahead and use whichever approach you're more comfortable with.

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

Ok Chris That definitely helped because now it's displaying the links from the backend. BUT... for some reason my links are not working properly or something in the page is wrong. Here is what I have. Maybe you can spot the problem.

Let me tell you what's happening first to give you an idea. When I bring my mouse over one of the category menu links it shows that it is pointing to the correct category number(good) BUT when I click on the link it loads all the listings instead of loading the listings from that category. I am not receiving any errors or anything it just keeps loading all the listings. Also now for some reason the region name for the actual listing in the Listing page is a number and not the name of the region.

You can test it out and see for yourself: http://www.gselection.com/dev/region-listings.php

Code on the "listings" page:

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

require_once "/home/gselect/public_html/cmsAdmin/lib/viewer_functions.php";

list($regionsRecords, $selectedCategory) = getCategories(array(
'tableName' => 'regions',
));

list($listingsRecords, $listingsMetaData) = getRecords(array(
'tableName' => 'listings',
));

?>

Code in the "Listings" page Body :

<h1><?php echo $listingsRecord['city_town'] ?> Listings</h1>
<p>Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam.</p>
<?php foreach ($listingsRecords as $record): ?>
<div class="product2">
<?php foreach ($record['photos'] as $upload): ?>
<div class="product-thumb2">
<div class="<?php echo $record['sold'] ?>"></div>
<a href="<?php echo $record['_link'] ?>"><img src="<?php echo $upload['thumbUrlPath2'] ?>"width="<?php echo $upload['thumbWidth2'] ?>" height="<?php echo $upload['thumbHeight2'] ?>" alt='' /></a></div>
<?php break; ?>
<?php endforeach ?>
<div class="product-description2">
<h2><?php echo $record['title'] ?></h2>
<h3><?php echo $record['city_town'] ?> | $<?php echo $record['price'] ?> | MLS#: <?php echo $record['mls'] ?></h3><br />
<p><?php echo $record['summary'] ?></p>
</div>
<div class="product-button2">

<a href="<?php echo $record['_link'] ?>"><img src="images/learn-more.jpg" alt="Learn More" title="Learn More" /></a> </div>
<div style="clear:both;"></div>
</div>
<?php endforeach ?>

<?php if ($listingsMetaData['invalidPageNum']): ?>

Results page '<?php echo $listingsMetaData['page']?>' not found, <a href="<?php echo $listingsMetaData['firstPageLink'] ?>">start over &gt;&gt;</a><br/>
<br/>
<?php elseif (!$listingsRecords): ?>
<div class="no-results">
Sorry, we currently have no listings in this region!
</div>
<?php endif ?>
<!-- /STEP2: Display Records -->

Menu:

<div id="navcontainer3">
<ul id="navlist3">
<?php foreach ($regionsRecords as $categoryRecord): ?>
<li><a href="region-listings.php?category=<?php echo $categoryRecord['num'] ?>"><?php echo $categoryRecord['name'] ?></a> </li>
<?php endforeach ?>
</ul>
</div>


I really hope that you can figure out what's happening because once this is rectified I will be pretty much finished the site. I know you can help me Chris, you are my only hope. Thanks.

Hi Dan,

You'll need to change the field name in the URL to match yours. Change this:

<li><a href="region-listings.php?category=<?php echo $categoryRecord['num'] ?>"><?php echo $categoryRecord['name'] ?></a> </li>

... to this:

<li><a href="region-listings.php?city_town=<?php echo $categoryRecord['num'] ?>"><?php echo $categoryRecord['name'] ?></a> </li>

Also, to fix your "Undefined variable" error, you'll probably want to do change this:

<h1><?php echo $listingsRecord['city_town'] ?> Listings</h1>

... to something like this:

<?php if ($selectedCategory): ?>
<h1><?php echo $selectedCategory['city_town'] ?> Listings</h1>
<?php else: ?>
<h1>All Listings</h1>
<?php endif ?>

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

I can't thank you enough for the help that you guys have given me over the past week or so. Exceptional really. I have asked questions in countless forums for several different applications that we use and no one even comes close to the kind of support that you guys give. Ultra impressed.

BUT...LOL, one final question and it's really not a deal breaker whatsoever but is there a way that I can get the name of the region to show up in the URL instead of a number? Like I said it's not a deal breaker but it really would be nice and a bit more SEO friendly. Thanks again.

Hi Dan,

We're only too happy to help. :)

You can add the name of the region to the URL (but you'll still need the number there). Try replacing this:

<li><a href="region-listings.php?city_town=<?php echo $categoryRecord['num'] ?>"><?php echo $categoryRecord['name'] ?></a> </li>

... with this:

<?php
$name = $categoryRecord['name'];
$name = preg_replace('/[^a-z0-9\.\-\_]+/i', '-', $name); # replace non-url-friendly characters with hyphens
$name = preg_replace("/(^-+|-+$)/", '', $name); # remove leading and trailing hyphens
?>
<li><a href="region-listings.php?name=<?php echo $name ?>&city_town=<?php echo $categoryRecord['num'] ?>"><?php echo $categoryRecord['name'] ?></a> </li>


I hope that helps! Please let us know if you have any questions. :)

Amazing!! That is exactly what I wanted. Thank you very much Chris you have been super helpful. Please tell Dave and Jason thank you for me as they also helped me out with issues I have been having with this project.

Hi Dan,

Firstly, it looks like you're putting records into the same variable ($listingsRecords) twice. You'll probably want to get rid of one of those getRecords() calls.

You could solve this with beta_lookupRelatedFields. Or, since you're already loading all your regions, you could do your own (simple) lookups:

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

require_once "/home/gselect/public_html/cmsAdmin/lib/viewer_functions.php";

list($listingsRecords, $listingsMetaData) = getRecords(array(
'tableName' => 'listings',
'perPage' => '6',
'orderBy' => 'featured',
'where' => 'featured = 1',
));

list($regionsRecords, $selectedCategory) = getCategories(array(
'tableName' => 'regions',
));

$regionsByNum = array_combine(array_pluck($regionsRecords, 'num'), $regionsRecords);

?>

then replace this:

<h3><?php echo $record['city_town'] ?> | <?php echo $record['price'] ?> | MLS#: <?php echo $record['mls'] ?></h3><br />

with this:

<h3><?php echo $regionsByNum[$record['city_town']]['name'] ?> | <?php echo $record['price'] ?> | MLS#: <?php echo $record['mls'] ?></h3><br />

Does that help? Please let me know if you have any questions.

Boy-O-Boy am I struggling with this. I never would have imagined that pulling a name from another table would be so tough. Ok so every solution you gave me has worked but I always end up with the same problem but on another page. This is the last page that is not displaying the region correctly so there really shouldn't be anymore questions left after this one.

Ok so every page is now showing the correct region except the actual listing page. You can view it here:

http://www.gselection.com/dev/listing.php?353-Querbes-308-2

Where it says "N.D.I.P" it should be pulling "Vaudreuil-Dorion" which is the correct region. Here is the code that's on this page:

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

require_once "/home/gselect/public_html/cmsAdmin/lib/viewer_functions.php";

list($listingsRecords, $listingsMetaData) = getRecords(array(
'tableName' => 'listings',
'where' => whereRecordNumberInUrl(1),
'limit' => '1',
));


beta_lookupRelatedFields(array(
'table' => 'listings',
'recordList' => &$listingsRecords,
'fieldList' => array( 'agent')
));
$listingsRecord = @$listingsRecords[0]; // get first record

// show error message if no matching record is found
if (!$listingsRecord) {
header("HTTP/1.0 404 Not Found");
print "Record not found!";
exit;
}

list($agentsRecords, $agentsMetaData) = getRecords(array(
'tableName' => 'agents',
));


?>
<?php

require_once "/home/gselect/public_html/cmsAdmin/lib/viewer_functions.php";

list($regionsRecords, $selectedCategory) = getCategories(array(
'tableName' => 'regions',
));

$regionsByNum = array_combine(array_pluck($regionsRecords, 'num'), $regionsRecords);

?>

Body code:

<h1><?php echo $listingsRecord['title'] ?></h1>
<div class="subtitle"><?php if ($selectedCategory): ?><?php echo $selectedCategory['name'] ?><?php endif ?>, Quebec | MLS#: <?php echo $listingsRecord['mls'] ?> | $<?php echo $listingsRecord['price'] ?><br />
Bedrooms: <?php echo $listingsRecord['bedrooms'] ?> | Bathrooms: <?php echo $listingsRecord['bathrooms'] ?>
</div>

Honestly Chris this is the last page that is not displaying the region correctly. I'm confident that you will know what is going on once to review the code. Thanks again.
