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.
