Remove record num from _link

Hi kblm,

What code exactly are you using at the top of your page, and can you provide the example URL that is being generated for "1 Main Street #3" and failing to find the record?

Thanks,
Chris

Can't give a URL right now because I'm on a protected server.

I can give you my details.

I have 2 pages, a listings page and a detail page.

On the listings page, within the foreach loop I create a link as follows:

<?php
$propertyLink = preg_replace('/[^a-z0-9\.\-\_]+/i', '-', $record['address']);
$propertyLink = preg_replace("/(^-+|-+$)/", '', $propertyLink);
?>

I then for each record create the manual URL like this:

<a href="/home-listings-detail.php?<?php echo $propertyLink ?>">LINK</a>

For a record that has a property address of 1234 Main Street, I get the nice URL of this: /home-listings-detail.php?1234-Main-Street

On the detail page, at the top I have the following:

<?php

//CODE USED TO REMOVE THE RECORD num from the URL
$title_like = preg_replace("/_/", '\\_', @$_SERVER['QUERY_STRING']);
$title_like = preg_replace("/-/", '_', $title_like);

// load records
list($listingsRecords, $listingsMetaData) = getRecords(array(
'tableName' => 'listings',
'where' => mysql_escapef('address LIKE ?', $title_like),
'limit' => '1',
));
$listingsRecord = @$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;
}

?>

For that test URL of /home-listings-detail.php?1234-Main-Street, the code works fine. It's loads the detail page.

However, if I change the property address to 1234 Main Street #3, the url it wants to go to is: /home-listings-detail.php?1234-Main-Street-3

For the detail page I get the error thrown from the CMS: Record not found!


Hope that helps.....let me know.

Hi Kevin,

Thanks for the details! I think what's happening here is that the adjacent space and number sign (" #") in "1234 Main Street #3" are getting turned into a single hyphen ("-") in the link, and that's being turned into a LIKE expression which is only looking for one character there (e.g. LIKE "1234_Main_Street_3").

I think the simplest solution here is to not truncate adjacent hyphens into one. Wherever you're generating links, remove the plus sign from this regular expression:

$query_string = preg_replace('/[^a-z0-9\.\-\_]+/i', '-', $record['title']);

It should look like this instead:

$query_string = preg_replace('/[^a-z0-9\.\-\_]/i', '-', $record['title']);

That should cause your link to have an extra hyphen in it, like this: /home-listings-detail.php?1234-Main-Street--3

Does that help?

I'll have to test some more but right now it looks to be working. Thanks Chris!!

Hi Kevin,

You can use the PHP function trim() to do this, for example:

$query_string = trim ( preg_replace('/[^a-z0-9\.\-\_]/i', '-', $record['title']) );

Hope this helps,

Jason thanks.

Technically that does help. Forgot I could just trim the string. However, I think I'm thinking of this incorrectly, because even when I trim the string, the CMS still doesn't find the record. I'm guessing because the record itself HAS the spaces, therefore the LIKE isn't matching?

I guess, can someone explain to be exactly what these preg_replace statements are doing? Maybe that will help me understand how to tackle this.


These are on the list page to form the link:

$propertyLink = preg_replace('/[^a-z0-9\.\-\_]/i', '-', $record['property_name']);
$propertyLink = preg_replace("/(^-+|-+$)/", '', $propertyLink);


These are on the detail page:

$title_like = preg_replace("/_/", '\\_', @$_SERVER['QUERY_STRING']);
$title_like = preg_replace("/-/", '_', $title_like);


Thanks for any help.

Hi Kevin,

To get a better idea of exactly what's happening, try putting a debugSql option in your getRecords call:

// load records
list($listingsRecords, $listingsMetaData) = getRecords(array(
'tableName' => 'listings',
'where' => mysql_escapef('address LIKE ?', $title_like),
'limit' => '1',
'debugSql' => '1',
));

This will print out the exact query being executed. If you could post this along with the exact value of the address field in the record you are expecting to retrieve. That should point us in the right direction.

Thanks

Jason,

Ok, with the trim NOT in the script....and the record having NO trailing spaces in the Title in the CMS.....this is the resulting query (which works):

SELECT SQL_CALC_FOUND_ROWS `property_listings`.*
FROM `cms_property_listings` as `property_listings`
WHERE (property_name LIKE 'Acorn_Lodge')
ORDER BY SUBSTRING_INDEX(property_name,'The ',-1)
LIMIT 1
tableName = 'property_listings' AND
fieldName IN ('photos') AND
recordNum IN (4)
ORDER BY `order`, num
SELECT SQL_CALC_FOUND_ROWS `accounts`.*
FROM `cms_accounts` as `accounts`
WHERE (`num` IN (1))
ORDER BY fullname, username


Now, if I just add a space to the end of the record title in the CMS....I then get this query:

SELECT SQL_CALC_FOUND_ROWS `property_listings`.*
FROM `cms_property_listings` as `property_listings`
WHERE (property_name LIKE 'Acorn_Lodge')
ORDER BY SUBSTRING_INDEX(property_name,'The ',-1)
LIMIT 1

Looks to me like something IS trimming this already, even though I haven't added the TRIM to the link.
