could we get the full source?

the URL of the results of my PHP is at:

http://wscottpadgett.com/CWMC/fee_content_query_test.php

and it shows all that is really pertinent to my question...


thanks!!!!

I'm not sure that javascript is decoding the variable into the form name as you intend. Given your application, could you pass the form number on the document to the function instead of the name? The form objects on a document are stored in an array, such that the first one can be referred to as document.forms[0], for example. So you could have:

function submitform(i) {
// i is the number of the form on the document, - 1.

document.forms[i].submit();

}


Just a thought, and I didn't test it!

i don't think i can use the form number, because the page arrangement will change according to how many items are in the database at the time of submission, but is it possible that javascript sets an associative array with keys of form names also??

this would work beautifully, but if i try this:

document.forms['form_name'].submit();

it doesn't seem to work....

is that because the above expression is evaluating the form_name var as it runs, or because the array just isn't associative as i thought i might be???

[wscottpadgett]

no associative array.

but i think i can write a script to yield an appropriate form number to pass for the appropriate from submitted from and fix it up that way.

thanks for the tip, i'm going to give it a shot.

just fyi, if i do run the explicit form # in the script it does work! so i think you got me half-way there.

i'll keep you posted.

thanks!

[wscottpadgett]

your tip about the existence of the forms array has me all set. i appreciate it.

i just placed a counter into the PHP that creates the forms so that i have a counter variable passed to the javascript function. then it correctly submits the right form!

thanks A LOT. you pulled me out of deep frustration!

:cool:

Hey, you know what? That makes my day too! Sounds like you're doing some substantial server side processing. Maybe some time I'll need to know how to do that as well.
