Parse form field?

[Mags]

Hi everyone,

Not a programmer, just need a little help.... I have a form with a
type="file" field, which uploads the file to the server (using
ColdFusion).

is there a way to parse the type="file" field to extract the file name
and store it into a DB when the form gets submitted?

Any help is appreciated. Thx!

Yes, but you would have to use server-side technology such as Perl, PHP,
ASP, JSP, ColdFusion, etc.

The exact solution depends on what database and server-side technology you
have available to you.

Actually, I am using CF - but I just figured it out:

STEP 1: grabbing the info from the 4th form element....

<script language="JavaScript">
<!--
function getValue(otherElement){
var path_name = (otherElement.form.elements[4].value);
window.document.myForm.the_file.value = path_name;
}
// -->
</script>

STEP 2: hidden file where this value will be passed to...

<form name="myForm" etc.>
<input type="hidden" name="the_file">

STEP 3: the submit button pushes the value into the hidden field....

<input type="submit" onClick="getValue(this);" name="Set"
value="Submit">
</form>

ColdFusion then can do all the database (which by the way is MS SQL) and
submission. No idea if this is the best way to do it but it works (after
testing for a couple hours). Maybe the code will help someone else. Now
I just need to run some string functions on the 4th form element to
extract the file name...

Thanks for responding!

The "type" attribute is required since HTML 4 and sufficient:

<script type="text/javascript">

This is obsolete, you can/should omit it and its closing counterpart.
[...]function getValue(otherElement){
var path_name = (otherElement.form.elements[4].value);
window.document.myForm.the_file.value = path_name;
}
[...]
<input type="submit" onClick="getValue(this);" name="Set"

It works if client-side script support is present, the DOM of the UA
provides means to retrieve the value of an input[type="file"] element
and if timing issues do not prevent the form from being submitted too
early, otherwise it does not work at all.
Maybe the code will help someone else.
I doubt that.
Now I just need to run some string functions on the 4th form element to
extract the file name...

It would be

var filename =
document.forms["myForm"].elements[3].value.replace(/.*[\\/]/, "");

But as you do have ColdFusion available, why do you not do the
whole thing server-side? It would be the only reliable solution.
