Autosubmit forms

[Kayamel]

Hi,

I have a huge form that partly extracts data from a database, partly takes user input and partly display data accoding to what the user types in the fields.

Say I have field 1, field 2, and field 3 etc... What I would like is when the user input something in field 1, there is an autoprocessing behind that display the corresponding data on field 2 while the user continues to fill the rest of the form.

Do I necessarily have to use javascript to do this or is there any way to do it in php ? I 'd prefer to have the smallest amount of javascript code possible in the page.

Since the PhP code is executed before it arrives at the user, you'd have to use javascript.

Leatherback,

Not trying to contradic you or anything by the following statement.

Can you provide a resource on javascript doing what he needs.

I would have thought something like ASP or C# would need to be used. I am probably wrong, but this is my attempt to learn as well.

Ah yeah, I always forget the server/client side difference between js/php. I guess I don't have much choice.
Thanks.

Hi Kudose,

Nope. Cannot provide you with a resource: I try to stay away from auto-submitting forms as much of possible. I hate the things, and have no info on it here... (I personally like to control what is hgappening when I visit a site. I serieously dislike any scripts runnig to mke my life easier, which always seem to fail when I load the page.

But you would need some sort of iframe to which you use an onchange: form.name.submit() action. The IFRAM will then process the request, and the javascript can then pick it up. Or you can just submit the whole formpage.

I jhave seen it pass by a lot in the past on this forum. Do a search for it..?

asp and C# (.NET) are both server-side, the same as php.

i havent tested this and i hope it will give you some ideas

<script>
function validatedata(formname)
{

formname.field2.value=formname.field1.value;
return true;
}
</script>

<form name="form1" method="post" action="">
<input type="text" name="field1" onKeyPress="return validatedata(form1);">
<input type="text" name="field2 ">
</form>
