I get an invalid argument when trying to create this output of pages to limit to 20 records per pages. I removed the line and it stopped the error, but the next and previous buttons will go on and on even if there is no more records so I am thinking it is my mysql_num_rows() function
I have gotten this script from here: http://www.phpbuilder.com/columns/rod20000221.php3 If you know of a better one or can help me out on this one, that is much appreciated Actual error is: not a valid mySQL result resource here is the code: <?php $numresults = mysql_query("SELECT * FROM booklist"); $numrows = mysql_num_rows($numresults); < ---------------------------------------- FAILS HERE // next determine if offset has been passed to script, if not use 0 print "Pages:"; if (empty($offset)) { $offset=1; } $connection = @mysql_connect("localhost", "", "") or die ("could not connect to database"); $db = @mysql_select_db("db", $connection) or die("Could not select database"); $sql = "SELECT id,title, author, subject FROM booklist LIMIT $offset, $limit"; $limit = 20; // get results $result = mysql_query($sql, $connection) or die("Could not execute query"); while ($row = mysql_fetch_array ($result)) echo "<tr><td>".$row['title']."</td><td>".$row['author']."</td><td>".$row['subjec t']."</td></tr>"; } // next we need to do the links to other results if ($offset==1) { // bypass PREV link if offset is 0 $prevoffset=$offset-20; print "<a href=\"$PHP_SELF?offset=$prevoffset\">PREV</a> \n"; } // calculate number of pages needing links $pages=intval($numrows/$limit); // $pages now contains int of pages needed unless there is a remainder from division if ($numrows%$limit) { // has remainder so add one page $pages++; } for ($i=1;$i<=$pages;$i++) { // loop thru $newoffset=$limit*($i-1); print "<a href=\"$PHP_SELF?offset=$newoffset\">$i</a> \n"; } // check to see if last page if (!(($offset/$limit)==$pages) && $pages!=1) { // not last page so give NEXT link $newoffset=$offset+$limit; print "<a href=\"$PHP_SELF?offset=$newoffset\">NEXT</a><p>\n"; } ?> -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
