Validate array problem

[micmac]

Hi all,
If i have a form, ie:

<form action="validate" method="POST" onSubmit="return checkform(this)">
<input type="text" name="ord[]" size="20">
</form>

and i send the array to validate.php which looks like the following:

<script Language="JavaScript">
<!--
function checkform(frm)
{
if(frm.ord[0].value=="")
{
        alert("<?php print $xxPlsEntr?> \"<?php print $xxName?>\".");
        frm.name.focus();
        return (false);
}
return (true);
}
//-->
</script>

how do i get it to check the input field ord[] for an entry?

Cheers,
micmac

what you are trying to do is not really clear to me. Are you trying to combine server-side way of working with client-side script?
Coz I see that you are trying to send ord[] to a PHP file which contains a Javascript code.

To provide client-side checking, put the code in that page itself. You can put it in another file as it would cause your browser to request a new page which has nothing to do with the first one.

I suggest server-side checking, for instance:

<form action="validate.php" method="post">
<input type="text" name="ord">
</form>

in validate.php

$ord=$_POST['ord'];
if (empty($ord)){
//error message here
}

If you're asking what I think you're asking (how to refer to a form field named "ord[]" in Javascript), this is covered in the PHP manual, both in its [man]FAQ[/man] and in the user notes in the variables from outside PHP section.
