tjhilder Posted December 23, 2005 Share Posted December 23, 2005 this is my question, would it be possible to count the numbers in a field in a table? like ... photo_album | photo_count (number of photos in the album) first album | 21 second album | 15 third album | 52 so that photo_count's contents are counted? 21 + 15 + 52 = 88 if possible, how would I do it?

fenway Posted December 23, 2005 Share Posted December 23, 2005 You mean like using SUM()? Try the following: SELECT SUM(photo_count) FROM photos Hope that helps.

tjhilder Posted December 23, 2005 Author Share Posted December 23, 2005 ah thanks, I keep seeing that in places but when I wanted to use something like that it never came to mind lol how would I display that on the browser?

fenway Posted December 23, 2005 Share Posted December 23, 2005 I don't know what you mean by "on the browser" -- you retrieve this aggreate value in MySQL (you should give it a nice alias, like sum_count), and then get it with PHP, and shove it out to the browser the way you do with any other PHP script. Maybe I don't understand your question. Quote Link to comment https://forums.phpfreaks.com/topic/3091-counting-numbers-in-mysql-field/#findComment-10355 Share on other sites More sharing options...
tjhilder Posted December 23, 2005 Author Share Posted December 23, 2005 this is the code I have (by what i thought you meant) $show_totals = "SELECT SUM(number) AS sum_count FROM gallery"; if ($r = mysql_query ($view_2003)) { $row = mysql_fetch_array($result); echo "{$row['sum_count']}"; } else { die ("Couldn\'t show the News because: <b>" . mysql_error() . "</b>. The query was $view_2003."); } I wanted to get the amount of photos from the gallery with MySQL and then echo them on the browser with PHP. sorry if that wasn't clear enough last time. -- TJ Quote Link to comment https://forums.phpfreaks.com/topic/3091-counting-numbers-in-mysql-field/#findComment-10358 Share on other sites More sharing options...

ryanlwh Posted December 25, 2005 Share Posted December 25, 2005 you applied mysql_fetch_array on $result which sould be $r. Glad that you figured it out by yourself.

fenway Posted December 25, 2005 Share Posted December 25, 2005 I actually missed that, as well as the change in the query variable name, too! Didn't look that closely, I guess.
