I'm working on editing an existing PHP form that seems to use Bootstrap to do the field validation (telling me if a required field is missing).
Currently, when you fill out the form and click Submit, a modal pop-up comes up that basically just prints your form data so you can review it before submitting. Then, within that modal is another Submit button that actually submits the form.
However, the validation of determining whether all the required fields are filled out only happens on the 2nd Submit button, not the first.
Is there a way I can tell my 1st Submit button to do the validation, and only open the modal pop-up if the validation passes?
Hello you can use Jquery. You can check with jquery first form values. If you need check with php you can use Ajax.

I'm using Symfony2 but i'm experiencing a troubling thing.
I have a form, with a textarea field, but each time i press 'enter' to go to the next line it refresh the page (without deleting the previous line)..
Do you have any idea where does it come from?
Thanks!
Well for sure you have a submit button on the form. On enter in a form you call the submit butt that refreshes the page!
In order to prevent that you can just make the button in the type="button" and bind a onclick function so that the submit button is not called on enter!
However; you will remove the enter feature that calls the submit on the entire form not just in the text area!
OR --> you can just call a function on keypres or keyup on the text area and e.prevetnDefault();
I hope my answers helps you!
I am using Twitter Bootstrap's modal control to create a popup form where a user can enter some input.
How do I go about getting the information from the form? In the past when I am just using a form on a page, I have used the post variable to get user input - but would that apply in this case?
Use AJAX, that way you can submit the form, get a response and then decide whether or not to close the modal window.
I'm just trying to understand the submit button within php.
I know that it performs that action stated within the form tag. So basically what I have is an form tag that only defines it's ID, i.e. no method attribute nor action. And within this form is a submit button. This input element only defines the type as submit, i.e. no name attribute nor id nor value.
Quickly describing the file: It has two input text elements which are required and a submit button. When i view this file in chrome, and i've clicked the submit button, a pop up shows below the required fields which i have not entered text in stating "required field".
I love this function however, it doesn't check for spaces, i.e. " ".
So back to my question, could someone possibly tell me what the submit button actually does or possibly what methods does it call when i click on it even though the form it is in has no action defined.
When the button is clicked, the browser detects this and submits the form back to the server. This has nothing to do with PHP, it's simply the browser implementing what the HTML specification stipulates.
Since your form does not have an action attribute, what happens is that the browser gathers the values of all eligible input controls in the form, turns that into a query string and makes an HTTP GET request to the current URL using that query string. The HTML5 spec covers this in detail.
The submit button offers one possible interface for the submission of the form. It's like the send button for a text message. While there are alternatives to submit the form, the submit button is the HTML option.
When a form's action is empty, the form submits the GET data to the page that form is on. (Basically, it reloads itself, with the new form data attached.) So you could write your PHP code at the top of the same page to manipulate the data.
In your PHP code at the top of the page, you can test whether or not your form sent data in those two required fields. If one or both are empty, you can echo a message to the user telling them the fields are required.
I have a form with a wysiwyg editor and I would like to add a preview button so the user can see how the content would look like in the website.
In order to do this I inserted another submit button wich gets the info from the form and redirects to a preview page.
All ok, but after clicking that button the form content disappears so the user can see a preview but it has no data in the actual form in order to make some changes or to submit the form in order to save the data.
So here's my question: can I have this preview button and also keep the data in the form after clicking the preview button?
What you need is either:
Repopulate the form from the preview function (that means manually fill in the form with the submitted data)
OR
Use Ajax to submit the form to the preview function and keep open the current edition page.
By the way, you can't have two submit for one form.
I have a form which has got five (5) file input controls along with other controls. This form also has got two (2) submit buttons.
I have used JQuery Validation plugin to validate form inputs.
Name of one submit button is "Upload_Images" and name of another is "Upload_Project".
What I want to do is that if user clicks on "Upload_Images" button all files controls should be validated and files uploaded to server but not rest of the data.
If use clicks on "Upload_Project" button then the whole form should be validated and the files are not already uploaded they should be first uploaded and then the project should be saved to DB.
Now if I click on any of the two submit buttons the form Validation kicks in and if there is invalid data it stops form submit process.
How can I achieve this?
Use javascript to change your form 'Action' property to redirect to wherever other page you need to go, then submit.
