TeddyKiller Posted March 28, 2010 Share Posted March 28, 2010 Well.. I know how to display a certain amount of characters. For example - This will display 50 characters. $synopsis = substr($row['story'],0,50); Keeping it simple, you could do something like... - This will display 50 characters, with a Read More after story snippet. $synopsis = substr($row['story'],0,50) .'..<a href="/my-page-to-display-news.php">Read More</a>'; As for only displaying Read More if there is more than 50 characters exceeded, you could do.. $synopsis = substr($row['story'],0,50); if($row['story'] > 50){ $synopsis .= '..<a href="/my-page-to-display-news.php">Read More</a>'; However this may display a resut if there is anumber bigger than 50, so you'll have to change it slightly to do it with characters. Could be either.. if(substr($row['story']) > 50) /* OR */ if(substr($row['story'] > 50)) Not sure though.. was an option I never tried.

dstar101 Posted March 28, 2010 Author Share Posted March 28, 2010 $synopsis = substr($row['story'],0,50) .'..<a href="/my-page-to-display-news.php">Read More</a>'; Thanks this code gets the work done never thought it was so simple I still want to format the text retrieved from the database using BBcodes (like one use in forums). And How can I filter PHP and Html Tags before entering the Text into Database Quote Link to comment Share on other sites More sharing options...
ignace Posted March 28, 2010 Share Posted March 28, 2010 LOL I laughed at: elseif($state =! 1){ $state = !1 <=> $state = 0 which means that the body (between { and }) of elseif($state = !1) never executes $synopsis = substr($row['story'],0,50); Is not a good idea you could get: He kissed my ass... while the long text would have been He kissed my assistant Use $synopsis = substr($row['story'], 0, strpos($row['story'], ' ', 50)); It also looks nicer if(substr($row['story']) > 50) /* OR */ if(substr($row['story'] > 50)) 'hello world' > 50 <=> 0 > 50 = always false in both above cases. You probably meant: if(strlen($row['story']) > 50) Quote Link to comment Share on other sites More sharing options...
dstar101 Posted March 28, 2010 Author Share Posted March 28, 2010 Is not a good idea you could get: Quote He kissed my ass... while the long text would have been Quote He kissed my assistant Do not worry about it ;) lols elseif($state =! 1){ I thought it meant if state is not equal to one Quote Link to comment Share on other sites More sharing options...
ignace Posted March 28, 2010 Share Posted March 28, 2010 I thought it meant if state is not equal to one That would be: != Quote Link to comment Share on other sites More sharing options...
