Products_Results.php short description length

Products_Results.php short description length

On Products_Results.php I would like to limit the display length of the short description to a fixed number of lines (probably three).
My current iteration of this page is here.
Products_Results.php

Thanks

I was able to do something like this on my product results page by adding in a new div around the product short description. For the div I added some inline styling to set the height and the overflow like this:

<div style="height:45px; overflow:hidden;"> the short description is here </div>

Thanks Eric

That I know I can do.
What I'm looking for is a way to truncate the length at a certain number of characters or lines.
That way I can make certain it doesn't look as if the dialog just runs off.
Using overflow:hidden it is possible that if the heading wraps to two or three lines that the text in the short description could be partially obscured by the edge of the div. And I would have to write all my short descriptions to fit in the allotted space, which could change with a redesign.
I remember reading about using a PHP script that could identify the end of a word and add an ellipsis to indicate…

No awkward words cut in half or lines of text blocked by the edge of the div.

Thanks

Eric, I found something

Eric

I found this…

$string = "Your feed string here";
$max = 100;
substr($string,0,strpos($string," ",$max));
That will truncate on the first whitespace found starting at the 100th position.

But being stupid about php - how would I employ this so that it would bring in the short description where needed?
And how would I add an ellipsis?

Thanks

Looks like a good example script, you can implement it on your products results page like this:

line 480

php:
<?php echo $row_WADAProducts["ProductShortDesc"]; ?>



Update it with your code like this:

php:
<?php
$string 
"" $row_WADAProducts['ProductShortDesc'] . ""
$max 100
substr($string,0,strpos($string," ",$max));
if(
strlen($string) > 100){ echo ". . .";}
?>

I think something isn't quite right.
That code seems to eliminate the short description entirely and insert an ellipsis in its stead.
Servers are down so I'm looking at a local copy.
When I upload I'll post back with a link.
Changing the value from 100 to a higher number just moved the ellipsis further down the div.

I just updated the code that you provided, this code you have is not printing out the description, it is just limiting the size of it. You will need to set this value to a variable and print this out to see it, you can set it to the string var and just add it to the echo on the next line like this:

php:
<?php

$string 
"" $row_WADAProducts['ProductShortDesc'] . ""
$max 100
$string substr($string,0,strpos($string," ",$max));
if(
strlen($string) > 100){ echo $string ". . .";}
?>

Eric, That works - sort of

Eric

That works but I get this error…

Warning: strpos() [function.strpos]: Offset not contained in string in /data/10/1/87/19/1087834/user/1133069/htdocs/intuhorses/Products_Results.php on line 476

on all the returns from the Gallery section.
You can see it here.

This code is coming from your script, it seems that it might not be crafted properly. Here is a link to the php page for the strpos function:

php.net/strpos

Here is an example of how the description is shortened within the PowerStore Admin area on the product results page:

php:
<?php echo substr(strip_tags($row_WADAProducts['ProductShortDesc']), 23); ?>

<?php 
if (strlen($row_WADAProducts['ProductShortDesc']) > 23) { echo "..."; } ?>



This one is limiting the description to 23 characters total, you can use some code like this and just update the recordset value and number of characters to display.
