I am working with website in which a user can login and then submit some forms. I want the user to avoid re-submitting the same form twice when he uses the browser refresh or when he goes to another page and then comes back to that same page using the browser back button.
I know of two solutions:
1. Redirect to a different page after form submission - The problem with this approach is that the website has many forms. So redirecting each form to a different one is not a very feasible solution.
2. A token can be stored in session (or somewhere) after each form submission. These tokens can be verified if the form is being resubmitted - The problem with this approach is that the user can submit
one form only once. I want the user to be able to submit the same form multiple times, provided with differetn data.
Is there a suitable solution where a form with same data is submitted only once, but there is no such restriction with different data?
Can the ASP request object be cleared after form submission, so even when refresh button is pressed, Request.Form elements dont have any data? (Storing ALL the information filled in each form during that session and then comparing for resubmit is not a clean solution I think??).
How can I make it that if the user clicks the back button --- the page will be automatically refreshed form the database (the asp) and not just show what was on the page before they submitted?
Currently i did 2 pages form and action pages, where form will have 2 inputs, and action page will insert the data into database.
but the i have tested once i keep refresh the action page, the data will be inserted again and again, anyone know how can i control this matter and avoid sql injection?
I have sometimes duplicate contents in a comments page because impatient people send the same form twice (they pressing in few seconds the Send button twice) . How can I avoid this?
I have a series a forms that submit data to different tables in a database. As it stands, when a user completes FORM 1 and clicks the SUBMIT button, the FORM 1 data is submitted (action = form2.asp, method = post) to ASP code at the top of FORM 2 (request.form("form1 field name") etc...), and submitted to the database with SQL code, also at the top of FORM 2(INSERT into...). Hence the submit button on FORM 1 directs the user to FORM 2, and submits the data which is exaclty what I wanted. However, I now need the users to submit multiple sets of data with FORM 1, and direct them to FORM 2 once they have finished using FORM 1. Most importantly, I need to pass a few parameters from FORM 1 to FORM 2, and have these parameters submitted to the database.
My main problem is getting a fresh form1 after submiting the same form1, in preparation for anoter set of data using the same form. Basically, the database has 'one to many' relationship tables. Form1 and form2 are both populating the 'many' tables, so that each form needs to be filled-in several times while retaining the key field of the 'one' table. At the moment submiting form1 takes me to form2. Is is possible to submit the data to the database, get form1 back again to submit more data, as many times as required, then click another button to load form2 when the user is finished with form1?
Can anyone please give me some pointers? or at least explain the concept of what I need to do. I am a novice and it's taking me a while to get to this stage. Any help will be greatly appreciated.
Is it possible to post FORM1 to itself and insert the data (i.e. place the request.form at the top of FORM 1) If so, how do I direct users to FORM 2 while retaining my parameters?
I know there really isn't a way to disable the "back button" on the browser BUT ... I'm trying to not allow multiple entries via a form submit when the back button is depressed on the browser.
Basically is there a code snippet that somebody can provide so that when a form is submitted and somebody attempts to go back by hitting the "back" button, that form information just entered won't resubmit into the database?
I'm having a small problem with refreshing my form after saving data in my database! here's what i'm trying to do:
* In my UpdateDB.asp form i display my database records and the user can make changes on whatever record he wants;
* after he'll have to save changes by hitting the save button on the form;
* when i receive the "save" action, i update the database; set a session variable that i'll use later to true ( Session("UpdateDB")= TRUE) and DISABLE the Save Button.
*once i'm done with it i reset my session variable to false ( Session("UpdateDB")= FALSE); and WOULD LIKE to "ENABLE" the save button; but i can't.
Everything works just fine but i can't "ENABLE" my save button? how can i refresh the page and get back the save button? i thought that after resetting my session variable to false would help me but i don't know how to use it?
I have a form, which uses a series of drop downs and text fields. However, when a user forgets to fill out a field, validation jumps in and points to the field which wasnt filled in correctly. However, the drop down fields ALL reset back to the original values when the form is submitted. I dont want this to happen, I want the form to retain its selected values if a mistake is made so the user doesnt have to fill out the form all over again.
I have an asp form. The page is kind long. After user scroll down and make some change on the items, the form needs to be refreshed with new selections (some controls may disabled based on the selection).
My question is, each time after the refresh, the form always go back to the top position. Since the form is quiet long. User may get frustrated if he/she have to scroll down the page to find the current position each time after make a selection change. Is there a way to remember the document postion before refresh the form, and reset the position after the refresh? I guess some javascript code may be able to do it. But so far I have no clue at all.
I have a page that is database driven. The customer want the option to sort the data by Date and by Title and have the default be by Date.I have two queries that show data by date and then by title. I have them in separate ASP pages that I can use a server side include depending on which button is pushed. I just don't know how to implement it.
how would I set up a page so thatI have the data defaulted to show by Date and two buttons at the top that one could click to toggle to show by Title if they so choose? -- all keeping this in one page.
When users clicked a unkown mime type link such as Zip on my website, a "Save/Open/Cancel" dialog box pops up. Is there a way to detect which button users clicked by using ASP? actually I only what to record the "valid" click -- when Open/Save was clicked.
I have a page with 2 frames. The first one has a link that loads a page in the second frame. This page has a button on it. When the button is hit, the page does some processing and loads another page in the same frame (the second).
I use ASP and response.redirect or javascript in the onclick event of the button to do the redirection. When I refresh the page by clicking the button on the browser (IE), the second frame becomes empty. Please note that the src attribute of the frame is not set.
If I set the src attribute of the second frame to some asp page and then navigate to another page inside the same frame, when I refresh the page, the initial asp page is loaded in the frame regardless of the asp page currently loaded into the frame.
It seems that when you refresh the page, the frames are reinitialized no matter what pages are currently loaded in the frames.
I solved the problem by redirecting to the main page in the top frame, passing some parameters and resetting the src of the frame to the desired asp page. Thus, when the page is refreshed, all the frames are properly refreshed too.
I move from one form to another when I click to a radio button. I can identify which radio button I clicked by trapping its value. but my problem is that there are a set of radio buttons followed by values being displayed from a join table.
I want to know the values displayed from the table. so that based on which I can do my further processing. Like the radio button is showing the name of student, his id, story id...and 2-3 more things. when I select the first radio button (its value = 0 ),
how can I know that the selected one is for which student_id and for which story_id.??? Code:
I have created a page that pulls up my data from an access database. A value has a link that goes to a detail page that I want to show all of the information for that value that was clicked.
How do I pass that value and then pull up the information for that value? Do I need to give you my code?
I have an ASP site that uses frames two frames. (yes I should be using include files, but we started ou using frames so we have been stuck with frames.)
When I get a page expired warning (I am not caching pages) and a user clicks refresh from the menu bar the user is taken back to the home page! The home page is a frame with a top frame that is repeated on each subsequent asp pages
The lower half of the home page is a login screen.
After login the next page is shown in the lower half of the frame. Refreshing within the individual frames is ok.
But when the Refresh from the menu bar is used the home page is returned any ideas why?

I'm getting crazy with this. You know that when you install office in your computer it install a plugin for Internet Explorer so when you click in a link to any office document it opens the document inside the explorer instead of asking to save it as normal files.

I need to provide a way to download a software and its corresponding manual from a web page.
So far I have done the sign in page where people give their data. I will then give access to a page with a link allowing to download the required file(s).

I do a SELECT * from table command in an ASP page to build a text file out on our server, but the export is not to allow a field name rows of records. The first thing I get is a row with all the field names. Why do these come in if they are not part of the table records? How do I eliminate this from being produced? Code:
