Each of your database seem to be containing integer unique identifier. My case is little different and the table does not contain integer identifier. How can i modify the option tag in while loop so that the drop down works fine. My code is not selecting the genomeVer value in the drop down list. My code is given as under. function autoSubmit() { var formObject = document.forms['theForm']; formObject.submit(); } <!-- organism SELECTION --> Select Organism <option value= "1" >human <option value= "2" >mouse <option value= "3" >rat <!-- genomeVer SELECTION BASED ON organism VALUE --> select GenomeVersion <?php while($row = mysql_fetch_array($result)) { // echo ("$row[genomeVer]"); echo "" . $row['genomeVer'] . ""; } ?> Thanks Fahim I was following your example for making a drop down list. Each of your database seem to be containing integer unique identifier.

My code is not selecting the genomeVer value in the drop down list.

My code is given as under.

function autoSubmit()
{
var formObject = document.forms['theForm'];
formObject.submit();
}

Select Organism
<option value= "1" >human
<option value= "2" >mouse
<option value= "3" >rat

select GenomeVersion

<?php
while($row = mysql_fetch_array($result))
{
// echo ("$row[genomeVer]“);
echo “” . $row['genomeVer'] . “”;
}

?>

Thanks

how can you make it happen that one selection of the dropdown affects 2 or 3 tables dropdown at the same time?

say, if you select DROPDOWN1, Dropdown 2 and Dropdown changes at the same time.

I'm trying to add to a existing dropdown from a textarea with a add button then it updates on the dropdown list? Hi, I’m trying to do something similar, but different.

Like you, I avoid Javascript at all costs! It just isn't for me. I love PHP but I don't like migrating MySQL into it too often but, alas, that's par for the course. Anyway, I think that I can use your script, and understand it, too! Thanks a whole lot for putting this out here! Wow, exactly what I’ve been looking for! Like you, I avoid Javascript at all costs!
