[RESOLVED] Checkboxes

[mmonaco]

I know its offtopic for this forum.

If I have a list of checkboxes
<input type=checkbox name='ary_dothis[]' id='dothis'>
<input type=checkbox name='ary_dothis[]' id='dothis'>
<input type=checkbox name='ary_dothis[]' id='dothis'>

And I would like to check them all, if i do formname.ary_dothis[].checked=true i get an error because of the brackets. If I do formname.dothis.checked=true it only works if theres one item with an id of dothis.

How can i workaround this?

yep way off topic... lets see if I can confuse you on how I do it:

for 10 boxes

here's the javascript function

function checkAll() {
for (var j = 1; j <= 10; j++) {
box = eval("document.form.grp_id" + j);
if (box.checked == false) box.checked = true;
}
}

an example of check box:

<input name="grp_id[]" type="checkbox" id="grp_id3" value="3" '.$checkgrp3.'>
so for each of the check boxes give them an id number

now $checkgrp3 would come out of the database (inside the while loop)

and this is in the while loop:

$temp = 'checkgrp'.$GRP_ID;
$$temp = 'checked';

you'll need a link to call all <a href="javascript:checkAll()">check all</a>

heres some javascript examples:
