RSS confusion

[lukeUrtnoedki]

ok, then 

Im stuck on one problem,

heres my assignment

Your RSS feed is to display these fields:

• Product Name
• Product Line
• Product Scale
• Product Vendor
• Product Description
• Buy Price formatted in US dollars

  The product name of each feed item, is to be a link to a product page. You may choose the format of the remaining item data.

I have most of it down, but looked at the available tags and made some guesses, is this ok?

<?php
require_once('db/conn.php');

try {
$stmt = $conn->prepare('SELECT productCode, productName, productLine, productDescription, productVendor, buyPrice FROM `products` WHERE productLine = "Trains" OR productLine = "Vintage Cars" ORDER BY timeStamp ASC LIMIT 10');

$stmt->execute();

if($stmt->rowCount()) {
while($row = $stmt->fetch(PDO::FETCH_ASSOC)) {
                    echo '<item>';
                    echo ' <link>http://php_class.teamluke.net/Assignment_9/product.php?Code='.$row['productCode'].'>';
                    echo ' <title>' . $row['productName'] . '</title>';
                    echo ' </link>';
                    echo ' <category>' . $row['productLine'] . '</category>';
                    echo ' <source>' . $row['productVendor'] . '</source>';
                    echo ' <description><![CDATA[' . $row['productDescription'] . ']]></description>';
                    echo ' <Price>'
// I looked and couldn't figure out if my code in the while loop makes sence.
// Does it to you?

 
.number_format($row['buyPrice'], 2) . '</Price>';
                    echo '</item>';
}
                }
} catch(PDOException $e) {
echo 'ERROR: ' . $e->getMessage();
}
?>

</channel>
</rss>

I looked and couldn't figure out if my code in the while loop makes sence.

Does it to you?

When i try to validate it, I get soo many errors though...

using [code] instead of a rich text paste

The CDATA stuff isn't needed for the first <title> tag.

 

For the <webMaster> tag, see the example in the RSS 2.0 Specification (https://validator.w3.org/feed/docs/rss2.html).

 

For the second <link> tag (child of <image>), see the note in the RSS 2.0 Specification (https://validator.w3.org/feed/docs/rss2.html#optionalChannelElements).

ok, made a few changes and this is where im at.

https://validator.w3.org/feed/check.cgi?url=http%3A%2F%2Fphp_class.teamluke.net%2FAssignment_9%2Frss.php

Every error occurred 10- times so the problem is everything in the while loop

 while($row = $stmt->fetch(PDO::FETCH_ASSOC)) {
        echo '<item>';
	echo '  <link>http://php_class.teamluke.net/Assignment_9/product.php?Code='.$row['productCode'].'>';
	echo '  <title>' . $row['productName'] . '</title>';
	echo '  </link>';
	echo '  <category>' . $row['productLine'] . '</category>';
	echo '  <source>' . $row['productVendor'] . '</source>';
	echo '  <description><![CDATA[' . $row['productDescription'] . ']]></description>';
	echo '  <Price>$' .number_format($row['buyPrice'], 2) . '</Price>';
	echo '</item>';
                    }

I sort of guessed on what tags to use (out of the ones I can) and I had no idea how to use a tag to describe the price.

Thanks for your help thus far

Most of the errors refer the tags used within the <item> tag. The available children tags (for <item>) are listed in the RSS 2.0 spec here: https://validator.w3.org/feed/docs/rss2.html#hrelementsOfLtitemgt

 

The specification provides examples on how to use the tags. Note that the <title> tag is a child of <item> and not <link>. And there isn't a tag for <Price>, but you could add that information to the <description> tag.

On a related note, did you see the "[help]" links to the right of the errors in the W3C validation page (https://validator.w3.org/feed/check.cgi?url=http%3A%2F%2Fphp_class.teamluke.net%2FAssignment_9%2Frss.php)?

 

They can help guide you to the solutions. 

[lukeUrtnoedki]

ok made some corrections.  But am having a hard time figuring out this last error

It looks like the feed is technically valid. The last two things (guid and misplaced item) are suggestions. With that said, did you see the help links?

• guid help: https://validator.w3.org/feed/docs/warning/MissingGuid.html
• misplaced item help: https://validator.w3.org/feed/docs/warning/MisplacedItem.html

[lukeUrtnoedki]

Ya, dont understand the warning,

 

Do you see the issue?

[lukeUrtnoedki]

ok, thanks

[lukeUrtnoedki]

the warning says to move all item elements to the bottom of the channel, arent they allready?

Hint: there is a tag in your code after the last <item> tag, but before the end </channel> tag. It rhymes with "batom".
