[PHP] validating form data via javaScript when stored in an array

2001-04-09 Thread Joseph Blythe 

G'day,

I was wondering if anyone knows how to get the following to work:

--snip from head--
script language="JavaScript"
//--
function validateForm(theForm) {
   if ( theForm.input[name].value == "" ) {
   alert("You must type a value for NAME.");
   theForm.input[name].focus();
   return false;
   }

}
!--
/script

--/snip--
--snip from body---

form name="form" method="post" action="whatever" onSubmit="return 
validateForm(this);"
input type="text" name="input[name]"
input type="text" name="input[address]"
input type="submit" value="submit"
/form

--/snip--

Now the above doesn't work as I think javascript does not understand 
arrays? or I don't understand how javascript deals with arrays??

Any help/suggestions would be great, sorry if this post is a little off 
topic in the way of javascript but I would not be having this trouble if 
I weren't passing the form data to php via an array :-)

Regards,

Joseph.

[PHP] validating form data via javaScript when stored in an array

2001-04-09 Thread Morten Winkler Jørgensen 

Joseph,

   You will have to declare
   SCRIPT LANGUAGE="javascript 1.2"

  myArray  = new Array();

  myArray[0] = "a string";
  myArray[1] = 11;
  myArray[2] = new Array();
   /SCRIPT

   since JavaScript 1.2 has arrays implemented.


Kind regards,
Morten Winkler

Thanks for that, but my problem being that I have just collected all my 
form data in an array:

input[keyname]

how do I now build the equivelent js array to validate the data?

I tried the following still does not work:

--snip from head--
script language="JavaScript1.2"
//--
input = new Array();

function validateForm(theForm) {
  if ( theForm.input[name].value == "" ) {
  alert("You must type a value for NAME.");
  theForm.input[name].focus();
  return false;
  }

}
!--
/script

--/snip--
--snip from body---

form name="form" method="post" action="whatever" onSubmit="return 
validateForm(this);"
input type="text" name="input[name]"
input type="text" name="input[address]"
input type="submit" value="submit"
/form

--/snip--

How do I force all the data into the javascript array, while still 
setting the array to input[keyname]?

Any help appreciated,

Regards

Joseph

I don't think you can name variables as varname[name] and access them like
that in javascript unless
varname[name] is initialize where varname is an array and name=index in that
array and it must be defined first.

I believe you will have to change the naming convention from var[keyname] to
var_keyname or something, and same for reading it from PHP.

or else name them as:
input_1
input_2
input_...
input_N
then you can access them in JavaScript as:
for (i=0;in;i++)
{
fld=eval("form.input_"+i);
if (fld.value=="")
{
  alert('error in field');
  fld.focus();
}
}

as for PHP and reading them, you have to do:
?
  for ($i=0;$i$n;$i++)
{
  $temp = "input_$i";
  $value = $$temp;
  echo "value $i=$value";
}
?

hope it helps.
