MarkBad311 Posted March 7, 2006 Share Posted March 7, 2006 This is gonna be tuff. I have an existing function in my library that querys the db and generates these links depending on the 'bar' field . **Problem I am making these results fit in to a one line button on a side naviagtion menu example :: [a href=\"http://www.eriescene.com\" target=\"_blank\"]www.eriescene.com[/a]. the second nav portion is two lines. some of the titles are too long. **Solution use some kind of regular expression:1.... starts from the begining of the title and counts in 19 characters 2.... and replaces the next two charcters with .. (two periods).3.... Forgets about the rest. [!--coloro:#FF9900--][span style=\"color:#FF9900\"][!--/coloro--]Note: Must work on whitespace, letters, numbers, special characters.[!--colorc--][/span][!--/colorc--]Here is the Existing Link Generating PHP/MYSQL CODE[b][!--coloro:#009900--][span style=\"color:#009900\"][!--/coloro--]///////////////////////////////////////////////Links to single Events//////////////////////////////////////////////////////////function sidemenu($connection) {global $nav_block;$table_name = "events";$sql = "SELECT id, bar FROM $table_name WHERE `date` BETWEEN DATE_SUB(CURDATE(), INTERVAL 1 DAY) and DATE_ADD(CURDATE(), INTERVAL 20 DAY) ORDER BY 'bar'";$result = @mysql_query($sql) or die(mysql_error());$num = @mysql_num_rows($result);if ($num < 1) { $nav_block = "<p>I am sorry there is no results</p>";} else { $nav_block .= "<ul class=\"menu\">";//if results are found loop through them and make a form selection block list. while ($row = mysql_fetch_array($result)) { $id = $row['id']; $bar = $row['bar']; $nav_block .= "<li><a href=\"http://www.eriescene.com/index.php?id=$id\">$bar</a></li>"; } $nav_block .= "</ul>"; }}[!--colorc--][/span][!--/colorc--][/b][!--coloro:#009900--][span style=\"color:#009900\"][!--/coloro--]$bar[!--colorc--][/span][!--/colorc--] is the variable we'll need to modify. something like[!--coloro:#009900--][span style=\"color:#009900\"][!--/coloro--]$bar = $preg_replace('findit, limit it and add two period chacters, $bar);[!--colorc--][/span][!--/colorc--]Try as I may stinkin regex's get me everytime.

I took the regex stuff from one of the O'rielly perl books and put together a 2 page regex chart that's come in handy, but a cookbook would be nice...

wickning1 Posted March 7, 2006 Share Posted March 7, 2006 Heh, sorry, I was just kidding. :) I used the Perl Cookbook and Programming Perl when I was learning regular expressions, but these days I have no need for such things.
