echo error statements?

[Tim_L]

Hi again,

Not sure if that's what they're called but at the moment I'm using JS to validate my form. Instead I'd prefer to use php to validate and then echo the error messages in a bold colour. Is it easy to do this? So for eg.

When they click submit button, php would check whether any required fields are empty or not valid and would echo in bold red that they need to fill it in.

I think that this would be better than a JS alert that can be quite 'aggressive'!

Yes, it should be fairly easy to do.

One common way is for the form to submit to the same page, and when any errors are detected, no actual processing is done, only the errors are displayed and the form displayed, with the fields filled in.

Would you be able to give me an example of the code?

I want to use it on a form which is inserting details into the DB. So if 'field1' = "" then don't submit form and echo this line etc.
