multipage

I'm trying to build a multi step/page form in PHP and CodeIgniter and I was wondering if any of you could help me. How can I have a multi step form in CI that updates rather than inserts again when you return to the previous step with the back button? How can I have a form that doesn't have those back button POST form resend messages? Edit: without JS if possible Thanks! Create a unique ID which you use in all steps of your wizard. Save that ID to the database upon the initial saving of your form. Forward this ID to the next steps using a input type="hidden" . When saving a step, first try to

I'm trying to understand the best options for pulling off a wizard form in ruby on rails. Ideally I'd like to have it so the application signup has a back and next button that allows the user to submit data in steps. So in step 1 they could fill out contact info. Once they are done they could click next and be on step 2 to fill out payment info, etc. If they make a mistake, they can click back and correct it. Some steps will be required, while others will not, but you do have to make it to the last step to submit the data to the database to sign up. They then need the ability to go back and

I am using jsPDF in my site to generate PDFs. But now I have multiple DIVs to print in a single PDF. which may take 2 to 3 pages. For example: <div id="part1"> content </div> <div id="part2"> content </div> <div id="part2"> content </div> my JS code This works but not as I expected, It add a part of the content(which cannot be included in more than one page). It removes html tags like br, h1 etc. function formtoPDF() { jsPDF.API.mymethod = function() { // 'this' will be ref to internal API object. see jsPDF source // , so you can refer to built-in methods like so: // this.line(....) // this
