Changing a recursive condition in a SQL/PHP website menu
I am modifying a site built in PHP with content drawn from a SQL database. The original developer had the navigation created with the following code. It creates the navigation from the CMS pages – it works fine for top level pages but I am trying to modify the way subpages are presented.
What I want it to do is when a subpage is present, it first opens a DIV containing formatting, then populates the subpagemenu by using the ‘while’ statement below. Finally, when the subpagemenu is finished, it closes the DIV.
I can’t seem to work out which condition ‘opens’ the subpage menu before it goes through the loop of filling out the subpage menu.
Any and all help appreciated – thanks!
<?
$pagesrc = $_SERVER['SCRIPT_NAME'];
$getPID_sql = "SELECT * FROM tblPages WHERE parentID = 0";
$getPID_result = mysql_query($getPID_sql);
if(!$getPID_result){print mysql_error()."<br />";}else{
while ($row = mysql_fetch_array($getPID_result, MYSQL_ASSOC)) {
$parentID = $row["pageID"];
$linkName = $row["pageTitle"];
$linkID = $row["pageID"];
print "<A href = '".$pagename."?id=".$linkID."'>".$linkName."</A> | ";
if($pageID){
$subpages_sql = "SELECT * FROM tblPages WHERE parentID = $parentID";
$subpages_results = mysql_query($subpages_sql);
if(!$subpages_results){print mysql_error();}else{
$rowcount = mysql_num_rows($subpages_results);
if($rowcount > 0){
while ($row2 = mysql_fetch_array($subpages_results, MYSQL_ASSOC)) {
$sublinkName = $row2["pageTitle"];
$sublinkID = $row2["pageID"];
$sublinkParentID = $row2["parentID"];
if($sublinkParentID == $pageID || $sublinkParentID == $PID){
print "<a href='".$pagename."?id=".$sublinkID."'>".$sublinkName."</a>";
}
}
}
}
}
}
}
