Form Data

[Anon]

I have a problem with forms my enquiry form is not remembering the data which is typed by the user.

That is when the user clicked the register button, I display any fields which require completion on a different form with a hyperlink back to the registration form. I use the javascript: history.back() to move to the previous page. For some reason the details entered are lost.

Can anyone tell me why?

I am using normal forms (no rocket science involved), and using a php file called "addregistration.php" to process the fields entered.

HELP!!!!

It sounds like the info the users enter in is not being cached. There are two basic alternatives for this functionality. The first is to just recall the form page, passing in all of the data either in an URL or using hidden form fields. The other option, is just shift your validation to the form page itself, using javascript. I am assuming that since you were using a javascript function, that this is a viable option. I personally prefer this method, and it really is pretty easy to implement. If you need a hand, just drop me a line

Hope this helps

Thanks for your help darren. I wonder why the data is not being cached. I am using Apache/PHP4 and MySQl on Windows 2000. Is there any configuration set-up for Apache to switch off caching.

On the subject of using the same form, what would be the best way to implement this.

Many Thanks

The caching is on the browser side. I've found that IE will remember much better than NS.

Ken is absolutely right...and I have never been able to figure out the reasons behind this...which is why I do all of my validation in JS...that, and Im lazy..🙂

What I do, is call a validate function with onClick of the submit button...ie...

<input type = "submit" name = "submit" value = "submit" onClick="javascript: return validate(yourformnamehere);">

and then I havein the header:
function validate(form){
//for textfield not empty
if(form.fieldname1.value==""){
alert('Fieldname1 is a required field');
form.fieldname1.focus();
return false;
}
return true;
}

and so on. Obviously, you can build really complex validation rules, but I have yet to have a rule I can't implement in JS. The one big drawback, is that if the user has JS turned off, you are hosed. The validation doesn't work at all...
But if that isnt an issue, you are set!

Hope this helps
