Show images in RSS feed / Also limited description length

Hi 8BG,

RSS feeds can be finicky, but this should work to display an image.<description>
<![CDATA[

<p><u>Here is an image thumbnail</u> </p>

<?php foreach ($record['image'] as $upload): ?>
<img src="http://www.my_web_site.com<?php echo $upload['thumbUrlPath'] ?>" width="<?php echo $upload['thumbWidth'] ?>" height="<?php echo $upload['thumbHeight'] ?>" alt="" />
<?php endforeach ?></p>

<p align="center"><strong><font color="#ba1419">My First Image</font></strong></p>
]]>
</description>

In general, any time you want to treat code as "code" in an RSS feed, you need to surround the code with CDATA tags.

Note: You'll have to add the URL to change the relative image thumbURLpath location to absolute.

As far as limiting characters, here are 2 excerpts from my CMSB Cookbook that may help.

DISPLAYING THE FIRST X CHARACTERS ON A LISTING PAGE
Add this at the top of the page or before you want to invoke the character limiting function:

<?PHP function textLimit($string, $length, $replacer = '...')
{
if(strlen($string) > $length)
return (preg_match('/^(.*)\W.*$/', substr($string, 0, $length+1), $matches) ? $matches[1] : substr($string, 0, $length)) . $replacer;

return $string;
}

?>

and then where you want to display your content:

<?PHP echo textLimit($record['your_field'], 100) ?>

LIMITING THE NUMBER OF WORDS SHOWN IN A PAGE
If you use the character limiting function that’s exactly what you’ll get, and words can be cut off. But if you want to limit the word count, Dave shares his usual uncanny wisdom:

Put this code at the top of your page, or before you want to invoke the word limiting function:

<?PHP
function maxWords($textOrHtml, $maxWords) {
$text = strip_tags($textOrHtml);
$words = preg_split("/\s+/", $text, $maxWords+1);
if (count($words) > $maxWords) { unset($words[$maxWords]); }
$output = join(' ', $words);

return $output;
}
?>

Then put this code where you want the words limited (to 5 words):

<?PHP echo maxWords($record['content'], 5);
?>
If you want to add ...more and a link, use something like this:

<?PHP echo maxWords($record['content'], 5);
?>...<a href="<?php echo $record['_link']; ?>”>Read More</a>

Hope that gets you started.

I am using the wysiwyg editor with barely any formatting at all but i do have several paragraphs. Limiting the words is making it all one paragraph. How can I keep my paragraphs?

Hi rez,

Do you mean makes it all one paragraph on the list page that is limited or on the detail page?

What does the source code look like with and without the limit words function?

Best,

Jerry

Hi rez,

Use this version of maxWords to keep your paragraph formatting.
<?PHP
function maxWords($textOrHtml, $maxWords) {
$text=str_replace("<p>","*P*",$textOrHtml);
$text= str_replace("</p>","*/P*",$text);
$text = strip_tags($text);
$words = preg_split("/\s+/", $text, $maxWords+1);
if (count($words) > $maxWords) { unset($words[$maxWords]); }
$output = join(' ', $words);
$output=str_replace("*P*","<p>",$output);
$output=str_replace("*/P*","</p>",$output);
$output.="</p>";

return $output;
}
?>


Let me know if that works for you.

i'm not getting this to work.
can somebody post a sample of where it is in the code?

thx
tim

Hi Tim,

What is the nature of the problem you're encountering? If you could clarify what's happening and attach the .php file you're working with, I can take a look for you.

Hope this helps.

it's not cutting down the amount of text displayed.
i'm sure i've done some thing wrong just not sure what.

Hi,

What's happening is that you're outputting the content of your about record in two different places:
<?php foreach ($about_usRecords as $record): ?>


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



<?php foreach ($record['images'] as $upload): ?>
<?PHP echo maxWords($record['content'], 5); ?>

You're only using the maxWords function the second time. Trying changing the code to this:
<?php foreach ($about_usRecords as $record): ?>


<?php echo maxWords($record['content'],5); ?><br/>
<a href="<?php echo $record['_link'] ?>">Read More</a><br/>


<?php foreach ($record['images'] as $upload): ?>

Hope this helps.
