I have 2 pages, namely main.html and list.php The Main Pageincludes the following code and consists of a dropdown that i want to pull some database records into by calling the function fillCategory contained in list.php

Content on main.html

<!doctype html public "-//w3c//dtd html 3.2//en">
<title>Page Title</title>
<script language="javascript" src="list.php"></script>
<body bgcolor="#ffffff" text="#000000" link="#0000ff" vlink="#800080" alink="#ff0000" onload="fillCategory();">
<FORM name="drop_list" action="yourpage.php" method="POST" >
<SELECT NAME="Category" >
<Option value="">Category</option>

Content of list.php


echo "
function fillCategory(

$q="select * from category";

echo mysqli_error($dbc);


echo "addOption(document.drop_list.Category, '$row[cat_id]', '$row[category]');";


I know that records are being pulled from the MySQL database since when i view i can see the following diplayed on the page:

function fillCategory( addOption(document.drop_list.Category, '1', 'Sport');addOption(document.drop_list.Category, '2', 'Music');addOption(document.drop_list.Category, '3', 'Art');

which are the contents (Sport, Music, Art) that i'd like to appear in my dropdown. However, i suspect that i shouldn't see the above being displayed in list.php Instead, it should probably be passed to main.html "unseen". Can anyone point out the probable error in my syntax. I can provide more detail on the database structure if it will help.

I think there's a mismatch here in the technologies, php is serverside, so everything it does happens on the server before the html is served, whereas javascript is clientside and doesn't begin doing anything until after the html/javascript has been delivered to the browser. You would use javascript if you wanted to modify the dropdown AFTER it had been rendered in the browser.

I don't think you need the script tag, what you're saying with that is that there's some javascript to execute and it's in the file list.php, but list.php contains php not javascript. The two technologies can't be mixed like this.

You can pull the records from the database and write them directly into the dropdown without any reference to javascript.

Hope that helps.

Hello ,

Mark can use both files. However he needs to include the list.php in the main.php. But really that does not worth it.
better to have the sql select on the main.php and populate a <option></option> tags with it.

Or if Mark uses DW he can always have a dynamically generated Select created by the program.
