PHP <-> JavaScript Problem

[IWeb]

Hello,

I am working with a dynamic list of checkboxes:

<input name="cbxList[]" type="checkbox" id="cbxList[]" value="1">
<input name="cbxList[]" type="checkbox" id="cbxList[]" value="2">
<input name="cbxList[]" type="checkbox" id="cbxList[]" value="3">
...

I am using cbxList[], so that I can threat the checkboxes as an array in PHP.

Until this point everything works.

But I also want to place a "check/uncheck all" button based on Javascript to check/uncheck all checkboxes:

Therefore I am trying to use the following javascript-code

function checkAll(field)
{
for (i = 0; i < field.length; i++)
	field[i].checked = true ;
}

function uncheckAll(field)
{
for (i = 0; i < field.length; i++)
	field[i].checked = false ;
}

and this code for the button:

 <a href="#" onClick="checkAll(document.form_3.cbxList)"><font size="1" face="Arial, Helvetica, sans-serif"><strong>mark 
  all</strong></font></a><strong><font size="1" face="Arial, Helvetica, sans-serif"> 
  | <a href="#" onClick="uncheckAll(document.form_3.cbxList)">unmark all</a></font></strong>

The JavaScript does not work because I am using "cbxList[]" instead of "cbxList".

Can someone help me to fix this?

Thanks,

To use your checklist as an array in php you only need to set the name of all checkboxes to chklst[] You can give them separte id's or all the same id for that mather. And you can use these id's to adress each checkbox seperaltly using javascript you aren't obliged to use the name.

So you can do something like this:

<input name="cbxList[]" type="checkbox" id="cbxList" value="1"> 
<input name="cbxList[]" type="checkbox" id="cbxList" value="2"> 
<input name="cbxList[]" type="checkbox" id="cbxList" value="3"> 

or

<input name="cbxList[]" type="checkbox" id="cbxList1" value="1"> 
<input name="cbxList[]" type="checkbox" id="cbxList2" value="2"> 
<input name="cbxList[]" type="checkbox" id="cbxList3" value="3"> 

Sorry for the tons of typos. I'm Dutch speaking.

That doesnt exactly answer his question as its related to Javascript.

I also suggest using name as well as id. This is because not all browsers support id. and im not sure on how Javascript will handle it.

Im not great with javascript so im sort of clueless with how to solve your problem

Despite being a Javascript question and not PHP, this is covered in the PHP manual's FAQ and is also mentioned in the user notes on the Variables from Outside PHP manual page. After all, it's not like you're the first person to ever come up against this.
