Validation - Form That Submits A POST Request When Data Is Submitted
Dec 9, 2009
I have a form that submits a POST request when data is submitted.
A Servlet then processes this POST request and a JavaBean is used to make some calculations. The HTML response is not generated within the Servlet but instead I forward the request to a JSP to generate the response. - This all works fine.
Here is my index.jps:
Regardless of whether incorrect input is given, the data is still POSTed to the server and calculated on or a Server Side error is given.
Am I correct in calling the function onclick?
The validation essentially needs to be so that:
- Student field contains a string
- Score1, Score2, Score3 and Score 4 contain a number between 0 and 100
I am analyzing header tags for submitting forms online in order to better understand how htmlhttp forms work- signing in to gmail, yahoo mail, and amazon, using the network tab of google developer tools, to view the http headers of requests and responses, and learn where they come from. I am seeing very peculiar behavior in my browser's (chrome)request headers when signing into amazon. The form data, always has the following two header names appended to the second and third to last places of the form data query: x=(some random number), and y=(some random number).
I have a multistep jquery form that validates user input and then should send me an email. Problem is, right now, I can only get it to validate the first page, then it sends the email before the rest of the pages are viewed. I'm just trying to delay the submission of the form until the "submit_fourth" button is pressed. I've got $25 via paypal for the one who sticks with this one for long enough to come up with a workable solution.
Here is my code I know it's a lot, but I wasn't sure how much would be HTML code is in the second post in this thread (it was just too much to fit in one go).
By the way this ONLY needs to work in IE, but it is better if it works in all browsers.
All Ajax libraries I've read use encodeURIComponent() on the name-value pairs extracted from forms before POST ing the result to the server with and xmlhttprequest. I can understand why this encoding is required in the case of a GET request and the form data is attached as a URI query string; however, why is the encoding necessary for POST requests?
I'm trying to submit form data to mysql database. The POST form action calls a javacript/ajax httpRequest. My php script has a redirect at the end of it on completion of data submission. My problem is after submitting the form, the redirection works, but no data is entered into database. I'm wondering if there is a problem with my httpRequest.
I've built a form in a mobile app where the user chooses a photo from the camera roll, they hit an upload button and the image is submitted to my server. The file is renamed by the PHP script and moved to the correct folder. All this works great.
I need a way to send the new filename back to my app and I'm not sure how exactly to do that.
The reason I need the name back from the PHP script is because I will then ask my users of the app to fill in a title and description and then i just want to submit all of the data together.
I'm having an issue when using a <button type="submit" with a form. The validation hook gets called but the form still submits regardless of the validation result. Is this a bug or mymisunderstandingof the button tag???BTW: I'm using a UI framework that generates Button tagsHere is a simple example
document.getElementById ('total').value = total
This code works perfectly for displaying the values on screen. However, when I send the form (PHP Post), the " total " field is empty. I have searched all over for possible solutions. But no solution yet.
1. document.getElementById ('total').INNERHTML = total .This does not even work on screen and total field is not updated on screen. Needless to say, the PHP Post variable was also empty.
I have a lot of tables and to get it to post some of the data into a form.
So say i have a location and a start date and end date, and when i select a radio and click submit the location and dates get put into the corresponding field in the form.
However i have a lot of tables and a lot of different options but want it to go to only one form. this form can be on a seperate page, but was wondering if its possible to get the form to appear on the same page, underneath the table.
I have a problem with sending data from a form to a php script with AJAX. To test if it works, I try to send data from the form, print it in the php with "echo", and then put it back in the initial html file.
The function stateChanged, basically says:
The problem is that the response is empty, but I don't know why. I have checked the input data and the postData variable says "firstName="+input (e.g. "firstName=Robert"), so that's not the error.
I've got a form which is acting as a calculator. Once the calculation is complete I want it so when the user presses a 'print' button it takes certain parts of the form data and displays them in a new window which would be designed for printing.
I have implemented a page based on tabs. Now how to submit the data is it just have the submit button on the last tab is it? On the other hand how best to show the error because there might be some fields not fill in the first tab itself and the user might be in the last tab.
I have a problem where if a form submission (set up to submit via AJAX) fails validation, the next time the form is submitted, it doubles the number of post requests - which is definitely not what I want to happen. I'm using the jQuery ValidationEngine plugin to submit forms and bind validation messages to my fields. This is my code below. I think my problem is that I need to unbind from the validationEngine plugin when the form fails, but I can't figure out how to do this.
