PHPNuke dynamic dependant drop down menu with two menus
Hi all
I have a phpnuke site where i want to generate a form with 2 dynamic drop downs pulling info from the database and where the second menu is dependant on the first menu selection.
The fields i am pulling from the database are Job Categories and Job Sub Categories, so the user chooses a job category and the second menu then displays all sub categories within that selection.
the database table contains 3 fields as follows:-
id
Category
Parent
the jobs are then entered in the database thus:-
id=1
Category=Engines
Parent=0
id=2
Category=Mechanic
Parent=1
id=3
Category=Health
Parent=0
id=4
Category=Doctor
Parent=3
etc i.e. if the Parent=0 then its a root category, if anything else then its a sub category, if it is a sub category then the Parent number is the id of the root category
I believe this can be done with OnChange, but would prefer a means of doing this on same page somehow ????
Here is some sample code i started playing with to give you an idea of where to start from:-
function show() {
global $sitename, $db, $admin, $module_name;
include('header.php');
OpenTable();
echo "<tr>;
echo "<td width=\"50%\"><font face=\"Arial\"><select size=\"1\" name=\"Category\">";
$sql = $db->sql_query("SELECT Category from nuke_jobs_Config where Parent='0'");
while (list($Category) = $db->sql_fetchrow($sql)) {
echo "<option value=\"$Category\">$Categ
}
echo "</select> Category</font></td>";
echo "</tr>";
echo "<td width=\"50%\"><font face=\"Arial\"><select size=\"1\" name=\"SubCategory\">";
$sql = $db->sql_query("SELECT SubCategory from nuke_jobs_Config where Parent<>'0'");
while (list($SubCategory) = $db->sql_fetchrow($sql)) {
echo "<option value=\"$SubCategory\">$Su
}
echo "</select> SubCategory</font></td>";
echo "</tr>";
CloseTable();
include('footer.php');
}

Store the results in a JS array an display the results.
Just like this:
<html>
<head>
<script>
var aDetail = [
["1", "Engines", "0"],
["2", "Mechanic", "1"],
["3", "Health", "0"],
["4", "Doctor", "3"],
["5", "Nurse", "3"],
["6", "Oil", "1"],
["7", "Car", "0"]];
function categSelected(theSel){
theForm = theSel.form;
opt = theForm.SubCategory.option
opt.length = 0;
if(theSel.value=="") {
opt[0] = new Option("--Select Subcategory--", "");
return;
}
for(i=0;i<aDetail.length;i
if(aDetail[i][2]==theSel.v
subCategoryValue = aDetail[i][1];
for(j=0;j<opt.length;j++){
if(opt[j].value==subCatego
}
if(subCategoryValue>""){
opt[opt.length] = new Option(subCategoryValue, subCategoryValue);
}
}
}
}
</script>
</head>
<body>
<form name="myform">
<table>
<TR>
<TD>Category</TD>
<TD colspan="3" >
<select name="Category" onchange="categSelected(th
<option>--Select Category--</option>
<option value="1"> Engines </option>
<option value="3"> Health </option>
<option value="7"> Car </option>
</select>
</TD>
</TR>
<TR>
<TD valign="top" >Sub Categories</TD>
<TD>
<select name="SubCategory">
<option>--Select Subcategory--</option>
</select>
</TD>
</TR>
</table>
</form>
</body>
</html>
replce the aDetail JS array values with the DB values. Do you need help in that?

congrats ldbkutty, on the nail :)
I had to change it ever so slightly to fit in with phpnuke requirements but it works the biz ;)
How could i expand on this in the future to account for more dropdowns, i.e. 3 or more ?

But, would be better if you could ask your other questions as new post.
BTW, i dont understand what you mean by: < How do i extract the variables out to post to the next routine, i.e. modules.php?name=$module_n
i need to obtain the category name and its ID >
May be i am too tired with this, but better if you could post this as a new question, so other experts might also try to help you.
Cheers!
