I have this query in PHP: $items2 = mysql_query(SELECT DISTINCT * FROM rev ORDER BY rev, $link); I have three rows with the same data on it, and DISTINCT seems to be not working, since I got all the rows, any ideas of what is going wrong? Without knowing how many fields you have and what they are, no. But you should realise that DISTINCT looks at _all_ selected fields in a record, so if you have an auto_increment id field in amongst those selected, all the records will be different.

RE: [PHP-DB] Multiselect List
That's not the problem. The problem is referring to the listbox via javascript. It doesn't like the format: formName.listBoxName[].value it has no problem with formName.listBoxName.value but then PHP doesn't seem to handle it correctly.

Re: [PHP-DB] Multiselect List
Ryan, you should be able to refer to the listbox in javascript as document.formName.elements['listBoxName[]']. Hope this helps... Dusty Ryan Jameson wrote: That's not the problem.

There is a function called MM_findObj which does exactly what you
need. I believe it originated from the Macromedia company (hence the MM
prefix) - possibly used by Dreamweaver for its scripting purposes, but I
digress.
Below is the funtion, and whenever you want to refer to oddly named form
elements, you call MM_findObj('oddlyNamedFormElement[]') (and it returns
an object reference to the form element that you can use normally).
function MM_findObj(n, d)
{
//v4.01
var p, i, x;
if (!d) {
d = document;
}
if ((p = n.indexOf('?')) 0 parent.frames.length) {
d = parent.frames[n.substring(p+1)].document;
n = n.substring(0,p);
}
if (!(x = d[n]) d.all) {
x = d.all[n];
}
for (i = 0; !x i d.forms.length; i++) {
x = d.forms[i][n];
}
for (i = 0; !x d.layers i d.layers.length; i++) {
x = MM_findObj(n, d.layers[i].document);
}
if(!x d.getElementById) {
x=d.getElementById(n);
}
return x;
}

RE: [PHP-DB] Multiselect List
Well i did not see why the name have to be with brackets [], can you show some code ? If you create the select in the way that i said, the name of the select will not have brackets , and the javascript have to work. --- Ryan Jameson (USA) [EMAIL PROTECTED] wrote: That's not the problem.

[snip]
An addendum to that, two points:
(mixed js and html examples, patently obvious which is which though)
1) You can use this for more than just form elements, if you give an
item an id. e.g.
div id=my_great_divhello world/div
h8_ie_my_great_div = MM_findObj(my_great_div);
2) This is just a general warning, but I used to stumble into it a lot.
IE creates variables/objects in the document namespace, essentially
polluting it - good for convenience, bad for cross-browser anything. As
an example:
input name=nothing
can be used as just nothing e.g.:
alert(nothing);
... and in fact, you get errors when you try to do things like:
nothing = MM_findObj(nothing);
because IE doesn't like to overwrite its pretty little objects. Which
nobody asked for. The only solution is to use different names for the
javascript variables describing/referring to your form/other elements.
h8_ie_nothing = MM_findObj(nothing);
