STRPOS() error? Why...

[madcat]

Hi:

I can't figure out why I get this error as other people have used this exact code on their sites with no problem.

I'm using a shopping cart program and trying to get a description area to use line breaks instead of characters to control the amount of space I have to describe.

Warning: strpos(): Offset not contained in string. in /home/felix/public_html/shop/index.php on line 344

...index.php looks like this...

</tr>";
}
$bgcolour=$colour_4;
while($row = mysql_fetch_array($result))
{ $product=$row["product"];
$description= $row["description"];
$price=$row["price"];
$sale_price=$row["sale_price"];
$image=$row["image"];
$title=$row["title"];
$title=stripslashes($title);
$description=stripslashes($description);
while ($br_count < 4)
{
$br=strpos($description,"<br>",$br);
$br=$br+1;
$br_count++;
}
$br=$br-1;
$description=substr($description,0,$br);
$br=0;
$br_count=0;
//$description=substr($description,0,100);

Thank you for any help...!

unless $br is set somewhere in your code before the snippet you posted, strpos() will die because the offset you are feeding as the third argument is not set.

i still don't quite understand what are ultimately trying to do here. you want to display only part of the description right?

Ok, tried to initialize but no go, same errors...

The description error is setup so that characters limit what you can do, this would hopefully allow line breaks...

Thanks,

if your working a string thats 4 characters long, and you try to specify an offset of 5, you will get that error.

try
echo strlen($description);
echo $br;

right before the call to strpos() to see it.

but i really dont understand what your code is supposed to do.

maybe take a look at explode(), that might be what your trying to do...

Seems as though his looking for 4 Brs hence the while loop a bit curious why? Anyway you may want to make it easier for people by using the [php][/php] tags in future when posting code.
