form processing before "submit" is pressed

[baffled_in_UK]

Hi,

My form and update to Db works fine, however if you accidentally hit the "Field Exit" key the form validation is not done and a record is written regardless of the required values not being entered.

Is there any way I can ensure this doesn't happen ? The Db update is dependent on this statement..

 if ($submit) {

is this sufficient because I have the feeling there is always a value in there.

Thanks

An example of your form code would probably help, but some pointers.

• Do not rely on client side validations such as java script, not everyone has these turned on - always validate the data within the PHP code in addition to any more friendly client side validation code.

• If you are unsure at what fields are being returned from the form when hittting submit or cancel etc then add in a loop to your program to echo out the values in the $POST and $GET superglobal arrays.

Hope that this general info helps.

Thanks.

It was actually a js error. I may well go down the PHP validation road when I am more comfortable with it.

If I knew how to emulate a js alert box I probably would.

Thanks again

There is nothing wrong with JS based validation, the main point is not to rely on it since anyone can switch it off and bypass any validations your site needs.

I personally advise doing both where applicable, the JS is nicer and can tell them upfront that the input is wrong but it should always be revalidated on the server side.
