Working with Form 'file field' data in ASP.

[daryl]

I am relatively new to ASp and I'm sure this is a simple problem and I'm just missing something simple.
----------------------
BACKGROUND:
I have got a form, with a few text fields and 3 'file fields' used to upload images.(this works fine)

All I want to do is get the value of each of the 'file fields'.
----------------------
MY QUESTION:
How do you get the value of a 'file field'?

[daryl]

Could this worK?

If I used the javascript below to get the value of the form field? I could run it on page unload.

<script type="text/javascript">
var obj = document.getElementById('filefield1');
</script>


Just thinking, it probably wont work but I will look into it.

no it wont work....well it might, but why use javascript!

you can simly call the forum field -

Code: Select all

field1 = request.form("field1")
response.write field1

where field1 is the name of your input box...

Actually you cant just call it. It does not work for file upload fields.

It works for all other form fields, but not for file upload fields.


The solution:

1.Put this javascript in the head.
<script language="JavaScript"><!--
function getExtension(value) {
return value.substring(value.lastIndexOf() + 1,value.length);
}
//--></script>


2.Put this 'onclick' script on the forms submit button.
<input name="submit" type="submit" value="Submit" onClick="document.MyForm.input1.value =(getExtension(this.form.FILE1.value));"/>

3.You also need a hidded field called in this case, 'input1'


How it works:

When the submit button is clicked, using the javascript function it takes the file field data and inserts it into a pre created hidden form field which you can then reference by name.

I could then tell which image upload fields were empty and then alter the path information after the image upload but before the path was entered into the database.
