HTML Forms, ONSUBMIT, PHP Functions

[mikefromvt]

Hi.

I have to verify and filter data received via std input through an
HTML form that is embedded within a php scripts. I am unable to apply
the filter to the std input data. I have been trying to push the std
input to the filter (in the form of a function) via the ONSUBMIT
feature of HTML forms. Should this work? Anyone know of a good,
inexpensive php script debugger for MAC OS 10.4 Intel?

Thanks

Mike

nope.

php executes on the server, not on the client. either use javascript to
'validate' on the client-side...regardless, use php to validate the data
once the form submits the data to the server.

Form data validation:

1) Client-side validation via CS Javascript
- validate data ONSUBMIT
- loop until you think it's right

2) Server-sdie validation via PHP (or whatever your language is)
- validate data via $_GET or $_POST
- if any of it is not right, send it back to the browser
- if it's all OK, do whatever your going to do

I use URLParams (Firefox extension) to verify what my HTML form sends.

Does this help?:
