hi. I have set up a multi list page (labeled news.php) and set up a page detail as newsDetail.php -- I'm having a problem with two things.

1) on the news.php page.. any way to change the link i.e. newsDetail.php?news-headline-to-come-here-4 to something else like... click here for more info?

2) on the detail page --- any way to show one news item instead of all of them????

THANKS! I'm loving this tool!

Hi,

For your first question, you just need to replace what appears between the <a></a> tags. Right now, you have this:
<a href="<?php echo $record['_link'] ?>"><?php echo $record['_link'] ?></a><br/>

You need to replace it with this:
<a href="<?php echo $record['_link'] ?>">*YOUR TEXT HERE*</a><br/>

You just need to replace "*YOUR TEXT HERE*" with whatever text you want displayed as a link.

We need to make a few more changes to newsDetail.php.

First, we need to restrict the number of records being returned to only return 1. Replace your current getRecords statement with this:


// load records
list($newsRecords, $newsMetaData) = getRecords(array(
'tableName' => 'news',
'where' => whereRecordNumberInUrl(1),
'limit' => 1,
));

This will only return one record. Now we need to select that record. Put this code right below:

$newsRecord=$newsRecords[0]; //select the first record.


Last thing we need to do is change the code where we're outputting our content. Replace all the code in "STEP 2" with this:


<!-- STEP2: Display Records (Paste this where you want your records to be listed) -->
<?php echo date("D, M jS, Y g:i:s a", strtotime($newsRecord['date'])) ?><br/>
<!-- For date formatting codes see: http://www.php.net/date -->
<span class="headline"><?php echo $newsRecord['title'] ?></span><br/>
<?php echo $newsRecord['content'] ?><br/>
<hr/>

<?php if (!$newsRecords): ?>
No records were found!<br/><br/>
<?php endif ?>
<!-- /STEP2: Display Records -->&nbsp;</p></td>

Give this a try and let me know if you run into any issues.

Hi cfdesign,

If I understand what you're asking, both are possible, and easy.

The showing only the first news item is as easy as inserting a <?PHP break ?> before your <?PHP endforeach ?> which will tell the loop to stop after it runs through once.

Changing the link to ...click for more... can be accomplished in a few ways.

Here's an excerpt from my CMSB Cookbook thecmsbcookbook.com that describes one approach using a word count to determine when the "click for more" is displayed.

In the head of your page insert the following code: (straight out of the code generator)
<?php

require_once "/your_path_to/cmsAdmin/lib/viewer_functions.php";

list($your_tableRecords, $your_tableMetaData) = getRecords(array(
'tableName' => 'your_table',

));

?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

In the body of your page, before you display your information, put the following code to set up the maxwords 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, where you want to display your articles and pictures, use something like this:

strupper forces the title to be displayed in CAPS, the number in the <?PHP echo maxWords($record['full_article'], 40); line sets the number of words to display before the ... (read more).

<?php foreach ($your_tableRecords as $record): ?>
<?php foreach ($record['your_image'] as $upload): ?>
<a href="http://www.your_site.com/your_detail_page.php?<?php echo $record['num'] ?>"><br /><br /><img border="0" src="<?php echo $upload['thumbUrlPath'] ?>" alt="" width="<?php echo $upload['thumbWidth'] ?>" height="<?php echo $upload['thumbHeight'] ?>" align="center" /></a>
<?php endforeach ?>
</td>
<td align="left" valign="top"><div><a href="http://www.your_site.com/your_detail_page.php?<?php echo $record['num'] ?>"><?php $event_title = ($record['title']); ?><?php echo strtoupper($title); ?></a></div>
<br />
<?PHP echo maxWords($record['full_article'], 40);
?>...<a href="http://www.your_site.com/your_detail_page.php<?php echo $record['num'] ?>">(Read More)</a>
<?php endforeach; ?>
</td>
</tr>
</table>

Styling is of course up to you.
Hope that gives you some ideas.

Best,
