Hi all,

I am having problem trying to put some code together.

I have the following code:

...
$query = "select * from tbl_news ORDER BY id DESC" ;
$result = mysql_query($query) or die("Query failed") ;

...

I then have this code:

$url_product = mysql_result($result,$i,'news_title');

which is displaying my domain name and the news title from the database like this:

www.mydomain.comthe-news-title-here ... now...I need to change it to do the following:

www.mydomain.com/news/fullnewsfile.php?news_title=

So, $url_product = mysql_result($result,$i,'news_title'); is dispalying:

this: www.mydomain.comthe-news-title-here

I need to add a "/" after the "www.mydomain.com then this path "news/fullnewsfile.php?news_title=" and after that the "news_title" field from the database.

Hope I've explained properly.

thanks

st3vo

or if your looping

$query = "select * from tbl_news ORDER BY id DESC" ;
$result = mysql_query($query) or die("Query failed") ;

if($rows=mysql_num_rows($result))
{
      for($x=0;$x<$rows;$x++)
      {
            $urlData = mysql_fetch_array($result);
            $url_product = "http://www.mydomain.com/news/fullnewsfile.php?news_title=".urlencode($urlData['news_title']);
      }
}

I just have a small problem with the code.

For example...The records are 1 foward so...title1 links to record 2 title2 links to record 3 and so on..

Is that hard to fix pls?

When you call "mysql_fetch_array()" it puts the information from the current row of the DB and puts into the variable it's assigned to, it then calls the next row so there is no need to use "mysql_result()" each time which is then moving the DB pointer forward 1.

I've replaced the code below
after             $dbData = mysql_fetch_array($result); //new

if you put print_r($dbData);
it will show you exactly what I mean

Kind regards
James
