Re: Too many records to display in one web page

Eduardo, The best way to do it is on both a php and sql level. Use sql's limit keyword in your query to return only the amount of records you want. For instance, page 1 will have LIMIT 0, 9 in the query. Page 2 will have LIMIT 10, 19. Then you can simply use *_fetch_array and a foreach(maybe) to iterate through all the values. If you want to have the the amount of records dynamically generate then either have a asdf.php?min=0&max=9 or just do min = (page * 10) - 10 and max = (page * 10) - 1. Many different ways to do this. However I find this one to be the most efficient.

problem with your example. Limit is not used that way Check out this page for further explanation http://dev.mysql.com/doc/refman/5.0/en/select.html#id3064319 Here is something I whipped together for this as an example <?php $page = 1; $rowsPerPage = 10; $start = 0; if ( isset($_GET['page']) && is_numeric($_GET['page']) && $_GET['page'] >= $page ) { $start = ($rowsPerPage * floor($_GET['page']) ); } $SQL = "select * from table LIMIT {$start}, {$rowsPerPage}" display results... ?> Let me know if I completely confused you. I am often confusing... Jim Lucas

Hope this helped.

When I run a query and display the records in a web page, this can become a problem because there might be too many records to be displayed in one single web page so I am trying to divide the total number of records and display them in multiple pages. Let's say, if the query returns 100 records then I would like to display the first 10 records and then put a navigation bar where I can go to the next 10 or return to the previous 10 records Is this done at a SQL or PHP level ? any experience on doing this ? Thanks a bunch Eduardo
