Question

I have problem with mysql_fetch_array() and while loop. I have the query:

$tagsquery = mysql_query("SELECT `url` FROM `tags`, `mapa-tagow`, `statusy` WHERE `tags`.`id` = `mapa-tagow`.`tag-id` AND `statusy`.`id` = `mapa-tagow`.`article-id` AND `tags`.`tag` ='$tag' ORDER BY `url` ASC ") or die("ERROR: Tags doesn't exist."); 

And results in while loop:

while($tags = mysql_fetch_array($tagsquery)) {
   echo "<a href='tags.php?url=$url'>$url</a>, ";
}   

When testing this query in PHPMyAdmin I have one more result than I get in PHP. I dont know why PHP always missing first result.

Answer 1

A few possibilities:

• You’re looking at a different copy of the same database
• You’ve already started fetching your result set earlier than your while loop

On a side note, you should build an array of your tag links, and then output them using implode… while(){ $tag_links[] = '<a href...';} print implode(', ', $tag_links);
