text cut to 30 char's

[ovisopa]

Hello ppl
I found a script that reads from a db some news in format Title - date and content ... this is the script:

<?
require ("database.inc.php"); //here are the username and pass
$result = mysql_query ("SELECT subject,content,timestamp FROM news ORDER BY timestamp DESC");
while ($data = mysql_fetch_array ($result))
{
?>
<tr><td><b><? echo $data["subject"]; ?></b>[<? echo date("d. m. Y", $data["timestamp"]) ?>]</td></tr>
<tr><td><? echo nl2br($data["content"]) ?></td></tr>

what I want is to include the second script witch will cut the content to 30 char's and add a link after for full story. But I don't know how to combine those scripts or how to store the content in $string .
This is the 2nd script.

<? 
function cutMore($string,$more_link,$max_length=30,$format='... [{link}]',$title='more') 
{ 
$string=trim($string); 
if(strlen($string)>$max_length) 
{ 
$string=substr($string,0,30); 
$last_pos=strrpos($string,' '); 
if($last_pos!=false) 
$string=substr($string,0,$last_pos); 
$format=str_replace('{link}','<a href="'.$more_link.'">'.$title.'</a>',$format); 
$string.=$format; 
} 
else 
{ 
/* it's not longer. Well, you can now either add the [more] link anyway or just do nothing 
* just uncomment the 2 lines by removing the "#" below if you want the [more] link added */ 

#$format=str_replace('{link}','<a href="'.$more_link.'">'.$title.'</a>',$format); 
#$string.=$format; 
} 
return $string; 
}
?>

Can somebody help me?

function shorten($str,$href,$max=33,$buffer="...")
{
	$outstr="";
	$words=explode(" ",$str);
	for($i=0;$i<count($words);$i++)
	{ 
		static $char_count=0;
		$char_count+=strlen($words[$i]);
		if($char_count<=$max)
			$outstr.=$words[$i] . " ";
		else
			continue 1;
	}
	return "<a href=\"viewarticle.php?id=$href\" target=\"_blank\">$outstr $buffer</a>";
}

echo shorten(nl2br($data['content']), $data['id']);

just change the query to "SELECT * " and have your article-viewer handler thing, in this case "viewarticle.php" query the id and pull the full content

that function should preserve whole words so it doesnt cut off in the middle of a wo....

theres probably an easier way to do this too🙂 but this is what im using for now

I't almoust ok.... the problem is:

First news is ok,but from the second one I see only the title and date and instead of content i see an error like this :

This to is just a test [23. 10. 2002]

Fatal error: Cannot redeclare shorten() in c:\web\apache\htdocs\sibiul\index.php on line 51

I don't know why that errro apears there and I really don't know how to fix it.

Can you help me again, pls?

[ovisopa]

I've tried again my script, from the first post, and finaly it's working but I see the same error :

Fatal error: Cannot redeclare cutMore() in c:\web\apache\htdocs\sibiul\index.php on line 51

Can U tell what's wrong with this?

Seems to me that you have put that function inside another function.

Make sure that the function is only read once. If its inside a function that is used more than one time, it trys to declare it again.

Since you are using an INLCUDE, put your cutMore() function in the
database.inc.php
instead of the index.php..

I ran into this same thing and for some reason, when you have an INLCUDE or a REQUIRE at the top of the page and try to add a function below that in the same page rather than in the INCLUDEd file, it gives that CANNOT REDECLARE error..

(There is probably a way around it, but I have not discovered it yet.. but there probably is..)

as for the char limitation, try something like this..

Store the limit you want in a variable..

$Limit = '40';
 

Count the number of chars when the form is submitted..
Store the first(number of chars defined by $Limit) chars in a variable like $FirstChars
and

if ($Count >= $Limit) {
echo $FirstChars." ...<a href='link_to_article.php'>CLICK HERE TO READ MORE..</a><BR>";

hope something in here helps..
