In your function there is at the end before the return statement: $previewtext = $whowcatvar; First $whowcatvar isn't defined. So it could be an answer. And I think u need to delete this line. -----Message d'origine----- De : Dwayne Heronimo [mailto:dwayne@xxxxxxxxxxxxxxx] Envoyé : vendredi 23 mars 2007 16:55 À : php-general@xxxxxxxxxxxxx Objet : Re: preview string with strlen PHP (help) Dear all, hmm.. sorry the $previewstext thing was a typo in my mail. But yes it is working but it will only display the first record of the recordset. I have like a list for items with short text in a page and of course made a query to make the database variables available. Which where the variable $row_show_cat['text']; comes from. This is why I thought that i may have to rewrite it into a function to display the $row_show_cat['text']; in a repeated reagion. I have rewritten my function: <?php function previewString($showcatvar) { $minitxt = $showcatvar; $len = strlen($minitxt); if ($len > 235) { $len = 235; } else { $len = $len; } $newstring = substr($minitxt,0,$len); $previewtext = $newstring; $previewtext = $whowcatvar; return $previewtext; } ?> And to to show it later in the page: <?php echo previewString($row_show_cat['text']); ?> but this still won't anywould display anything. :S Please let me know.
