Save and return to same place on page

[eluser]bazianm[/eluser]
I have a web system that I inherited from another developer. He used CodeIgniter.

We have a form that is basically a huge series of tables. Think of it like a long excel sheet. The users are entering their data (the data is organized into categories) and after each category there is a button where they can click save and save their work.

The problem is that the save button, which does a submit on the form, reloads the form and brings them right back to the top.

Is there a way I can return the user to the place they were at on the page?

Thanks in advance for any assistance...

Ciao,
every time you submit a form...your reload the page.
Have you think to submit the form with asynchronous method (ajax), so you don't need to reload the page.

Either you use AJAX for submitting just the form but not reloading the page, OR
you add anchors to your page and add these anchors as a hidden input field to the form. On submit you just check for that input-field and reload the page to the appropriate anchor-tag. That's the easier version because AJAX can be a real pain on setting it up.

Using jQuery makes AJAX pretty simple now a days. What took 20-30 lines of code before, can now be done in 1. This also is a much better time saver than frequent page reloads, and then scroll. Also, nice plugins like jEditable can speed up data entry, as it can take a page element and let you edit in place. Losing focus of the form field automatically submits it via jQuery/AJAX.

Wow. Thanks. I have never used Ajax before. Can you recommend a good resource to learn about it?

The [url="http://api.jquery.com/jQuery.ajax/"]jQuery AJAX[/url] api is a good place to start. There are some simple examples there. Also using the [url="http://api.jquery.com/jQuery.post/"]$.post()[/url] function which derivative to $.ajax(), without all the granular options.
