Tom,
Here is how you would paginate in PHP.
/****************************************/
// Number of records to show per page:
$display = 4;
// Determine how many records there are.
if (isset($_GET['np'])) {
$num_pages = $_GET['np'];
} else {
$query = "SELECT * FROM mytable";
$query_result = mysql_query ($query) or die (mysql_error());
$num_records = @mysql_num_rows ($query_result);
if ($num_records > $display) {
$num_pages = ceil ($num_records/$display);
} else {
$num_pages = 1;
}
}
// Determine where in the database to start returning results.
if (isset($_GET['s'])) {
$start = $_GET['s'];
} else {
$start = 0;
}
// Number of records to show per page:
$display = 4;
// Determine how many records there are.
if (isset($_GET['np'])) {
$num_pages = $_GET['np'];
} else {
$query3 = "SELECT * FROM mytable";
$query_result = mysql_query ($query3) or die (mysql_error());
$num_records = @mysql_num_rows ($query_result);
if ($num_records > $display) {
$num_pages = ceil ($num_records/$display);
} else {
$num_pages = 1;
}
}
// Determine where in the database to start returning results.
if (isset($_GET['s'])) {
$start = $_GET['s'];
} else {
$start = 0;
}
