In the last post i was thinking on this hack banzer wrote for b2, it was useful for me,but with the latest renaming of wp files and tables its out of order:
function preview_posts($the_cat = “1”, $last_char = “0”, $n_posts = “3”, $pr_more = “<b>»</b>más…”, $set_date = “nohour”, $the_file = “b2.php”, $pr_before = “<img src=\”images/arrows.gif\” width=\”8\” height=\”8\” /><b>”, $pr_aftertitle =”</b> <i>”, $pr_afterauthor = “</i> “, $pr_afterdate = “<br><br>”, $pr_after_pr = “<br>”, $pr_ending = “<br><br>”) {
#this function by Benzer at benzer@arkania.org http://benzer.arkania.org
global $tableposts, $querycount, $postdata, $authordata, $tableusers;
if ($the_cat != “”) {$choose_cat = “WHERE post_category=’$the_cat'”;}
else {$choose_cat = “”;}
$query=”SELECT * FROM $tableposts $choose_cat ORDER BY post_date DESC LIMIT $n_posts”;
$result=mysql_query($query);
$querycount++;
while($row = mysql_fetch_object($result)) {
$pr = explode(“
“, stripslashes($row->post_content),2);
if ($last_char != 0) {$preview_tx = substr(stripslashes($row->post_content), 0, $last_char);}
else {$preview_tx = $pr[0];}
$author_id = $row->post_author;
$the_author = mysql_query(“SELECT user_nickname FROM $tableusers WHERE ID=’$author_id'”);
$the_author2 = mysql_fetch_object($the_author);
if ($set_date == “nohour”) {
$no_hour = explode(” “,$row->post_date);
$the_date = $no_hour[0];
} else {$the_date = $row->post_date;}
echo $pr_before.stripslashes($row->post_title).$pr_aftertitle.$the_author2->user_nickname.$pr_afterauthor.$the_date.$pr_afterdate.$preview_tx.$pr_after_pr.”ID.”\”>”.$pr_more.”“.$pr_ending;
}
}

Well, is not a perfect code but it does the trick (i made some modifications from a previous hack for b2) , sure somebody would improve it. add this lines at the end of your template-functions.php file:
function preview_posts($cat=””, $limit=””, $predate=””) {
global $tableposts, $tablepost2cat;
//$post_amount = “post_content AS content”;
$post_amount = “SUBSTRING(post_content,1,350) AS content”;
$sql= ” SELECT ID, post_title, DATE_FORMAT(post_date, ‘%d/%m/%y %h:%i’) AS formatted_date, ” .
” $post_amount ” .
” FROM $tableposts,$tablepost2cat ” .
” WHERE ID=$tablepost2cat.post_id and $tablepost2cat.category_id=$cat” .
” ORDER BY post_date DESC LIMIT $limit”;
$result=mysql_query($sql);
WHILE ($row = mysql_fetch_array($result)) {
echo($predate.$row[‘formatted_date’].'<h4>| ‘.
stripslashes($row[‘post_title’]).'</h4>
‘.stripslashes($row[‘content’]).'[…]
…more‘.’
‘);
}
}
,in your template add this code where you want to display posts:
<?php preview_posts (“catnumber”,”npost”) ; ?>
, where catnumber=the number of the category you want to select (eg. 1 or 2 .., and npost=the number of posts to be shown: 4, or 3.

Sorry, replace above code with this, i missed some lines:
function preview_posts($cat=””, $limit=””, $predate=””) {
global $tableposts, $tablepost2cat,$siteurl, $blogfilename;
//$post_amount = “post_content AS content”;
$post_amount = “SUBSTRING(post_content,1,350) AS content”;
$sql= ” SELECT ID, post_title, DATE_FORMAT(post_date, ‘%d/%m/%y %h:%i’) AS formatted_date, ” .
” $post_amount ” .
” FROM $tableposts,$tablepost2cat ” .
” WHERE ID=$tablepost2cat.post_id and $tablepost2cat.category_id=$cat” .
” ORDER BY post_date DESC LIMIT $limit”;
$result=mysql_query($sql);
WHILE ($row = mysql_fetch_array($result)) {
echo($predate.$row[‘formatted_date’].’ ‘.
stripslashes($row[‘post_title’]).’
‘.stripslashes($row[‘content’]).'[…]
…more‘.’
‘);
}
}
