Somehow when moving a site to a newer server, the php code broke. We did have it tested with a temporary site first, but it still broke.
All of the dynamic links for listings no longer work. I have a next button that does nothing except change the url. It still shows page 1 of 5 when you click next. I do know that something is right though, because at the top of this page, it gets the number of records and displays it from the database.
I've heard this code is old and that a new site is being made altogether, so all I need to do is fix the errors. I don't need to re-do the entire page, since it would be a waste of time. They will be scrapping it in the next couple months anyway.
I'm more of a .NET developer, so I'm not even really sure how to error check a PHP site. Here is the code that is broken and the function that defines those variables.
<?php
echo "<br>\n";
echo "<strong>";
if($page_num > 1) {
$prev_page = $cur_page - 1;
echo " ";
echo "<A HREF=\"$PHP_SELF?action=list_records&sort_order=$org_sort_order&order_by=$order_by&cur_page=$prev_page$search_link\"><< Previous</A>\n";
}
if($page_num < $total_num_page) {
$next_page = $cur_page + 1;
$last_page = $total_num_page - 1;
echo " ";
echo "<A HREF=\"$PHP_SELF?action=list_records&sort_order=$org_sort_order&order_by=$order_by&cur_page=$next_page$search_link\">Next >></A>";
}
echo "</strong>";
?>
function list_records() {global $tbl_units, $tbl_members;
global $unit_array, $location_array;
global $default_sort_order, $default_order_by, $records_per_page;
global $sort_order, $order_by, $cur_page, $search_db, $search_txt, $search_link;
global $PHP_SELF;
$query = "SELECT count(*) FROM $tbl_units
INNER JOIN $tbl_members ON $tbl_units.memberid = $tbl_members.username
WHERE $tbl_members.status = 'Active' AND $tbl_units.status = 'Available' $search_db";
$result = mysql_query($query);
if(!$result) error_message(sql_error());
$query_data = mysql_fetch_row($result);
$total_num_user = $query_data[0];
$page_num = $cur_page + 1;
$total_num_page = $last_page_num
= ceil($total_num_user/$records_per_page);
if($total_num_user > 0) {
echo "<CENTER><H3>$total_num_user unit(s) found. ";
echo "Displaying the page $page_num out of $last_page_num.</H3></CENTER>\n";
} else {
echo "<CENTER><div class='vacancy'>No vacancies at this time!</div></CENTER>\n";
}
if(!empty($search_txt)) echo $search_txt;
if(empty($order_by)) {
$order_by_str = "ORDER BY $default_order_by";
$order_by = $default_order_by;
}
else $order_by_str = "ORDER BY $order_by";
if(empty($sort_order)) {
$sort_order_str = $org_sort_order = $default_sort_order;
$hold_order = $sort_order;
$sort_order = 'DESC';
}
else {
$sort_order_str = $org_sort_order = $sort_order;
$hold_order = $sort_order;
if($sort_order == 'DESC') $sort_order = 'ASC';
else $sort_order = 'DESC';
}
if(empty($cur_page)) {
$cur_page = 0;
}
$limit_str = "LIMIT ". $cur_page * $records_per_page . ", $records_per_page";
$query = "SELECT $tbl_units.* FROM $tbl_units
INNER JOIN $tbl_members ON $tbl_units.memberid = $tbl_members.username
WHERE $tbl_members.status = 'Active' AND $tbl_units.status = 'Available' $search_db
$order_by_str $sort_order_str $limit_str";
$result = mysql_query($query);
if(!$result) error_message(sql_error());
If someone can help me figure out how to get my links to work, I would really appreciate it! I've tried a couple things here and there, but I can't get the page to redirect to the next page of results.
