I am trying to do something really basic but can not seem to find a tutorial for it.
I have created a simple web form using HTML what I need todo is create a php file that will read the web form, open a new browser window (or display in same page) the contents of the web form, do toy guys have any tutorials on this?
Many thanks
Chris
I'm sure many will post different links to tutorials that they like, but I thought I would just give you the basic. The key parts to the form are the method and action. The Method attribute tells ths browser how to submit the data, either through GET or POST. The action attribute tells the browser where to submit the form. (In your case it will be, somepage.php) If you ever need the form to submit back to itself, you can here use explicitly type the page name or you can use use PHP to dynamically insert the page name. Finally, make sure that all your form fields use the name attribute, as this is how php will access the elements.
On the php side of things, your form variables will be stored in either $_GET or $_POST depending on how on method you used to submit your form. For example, assume you have a input element of type text with the name 'FirstName'. Within php you can access this by doing
<?php
var firstName = $_GET['FirstName'];
?>
This should be enough to get you started. Be sure to check out the php docs and the other tutorials listed on this page for a more details.
Please look at this tutorial: http://www.learnphp-tutorial.com/HtmlForms.cfm
And you can find many more tutorials if you search it on Google.

I am fairly new to using PHP so bear with me if this is a stupid question
I have a form that comprises a number of radio buttons, the action is set to redirect to the same page and the method is GET.
A click on a radio button gets data from the database. The data is used to redisplay the same page with changed content.
The page URL has PHP arguments in it like the example below
localhost/basesite/mypage.php?itemID=8&name=city&number=9
When I access the page and click on a radio button I get a page with “no arg” because the URL reads
localhost/basesite/mypage.php?number=6
Two of the arguments are missing and that the last one is incorrect.
With no change whatsoever to the code except using ”post’ instead of “get” the whole thing works flawlessly.
I have used
form action= "" method=“get”
form action= “#” method=“get”
and many other actions using $_SERVER["REQUEST_URI”], $_SERVER['QUERY_STRING'] etc and combinations thereof.
Those that worked with POST did not work with GET.
I do not need to use POST as data is not written only retrieved from the database so I have no worry about data being written more than once.
If I have to I will use POST but if the user refreshes or uses the back button then the usual warnings will be issued by the browser.
What am I missing?
you should you use $.get which is a jquery method.
First, you should share your full source code for better understanding your problem. And also you have to use post method to submit a radio button values to get some value from your database. Form data can be submitted using these two methods (get and post). Both are used for the same purpose, but stands apart under some specifications. As in GET method key values are passed in the Url while in POST, the information transfers in a hidden manner.
Sorry folks. It was a badly formed URL due to me not fully understanding how to set a hidden element.
So im asking what options do I have other than redirecting GET variables when Im trying to repopulate a form?
Im thinking I can create session variable and use that also. Am I correct that these are the ONLY 2 ways?
What I have now is:
if ( count($m) > 0 ) {
// there is an error in fields filled out so we are sending user back to form.
$_SESSION["myarray"] = $m;
header("location: ./edit.php?datefield=".$datefield."&text=".$entry."&flag=".$flag);
}
but this reveals my variable to the user. I want to avoid this.
UPDATE
I re-worded my question and the code to be clearer.
I also like found that the solution for me was to use an include('edit-error.php'). Which is basically the original edit.php with everything stripped out but the code needed to generate the form, and I populated edit-error.php with the needed variables. I never had this in my tool box before so I am grateful to the user who suggested it.
One way that you can consider for hide information (not totally, but more stronger than GET) of user is create a JSON with your infos and send a POST request to your page.
Personally, I still preferring sessions, but there are other ways.
The solution I used was provided my user pala_ , so thanks pala_ I up voted your comment.

This allows me to conduct server side validation and redisplay the form again with user input, so they can resubmit. I was using header(Location) with paramaters to submit as GET and I didnt want that. Using include() is a perfect solution for me.
I am new to html, I would be really glad if you can help me with this.
I have a web page where there is a list and some other text inputs and buttons. This option list can be populated by clicking the "add" button in the page, this add button is to direct to another page and in that page there are some chekboxes, those which are checked are loaded back to the main page,(where I have the list) .
At the end data in the main page needs to be loaded to the database, (what is in the list and in the text inputs).
Since I'm new I just know little about php and html, I thought I should have a form within a another form(form to "add items", form to load to the database) and it is not possible in html. Can anyone suggest the best way to do this? Do I need to use javascript?
Why can't the extra inputs (the ones that would be in the second form) be part of the first form? I think the question will become clearer if you post a sample form so we can see the relationship between the two forms.
But overall, since you're ultimately only submitting one form, then maybe all the inputs belong together. If what you're calling the second form isn't supposed to be visible right away, you can still have it be part of the same form, but only reveal it when needed.
Again, some sample data would help to understand the exact context of your question.
in php if you use input name="somename[]"
for a number of input elems
you will get an array in $_POST['somename'] and access all the values.
I think what you're after - if I understand you correctly - is ajax. Ajax allows you to asynchronously send data to/from another script without leaving the current page. This is accomplished using JavaScript. In your case I think what you need to do is set an onclick event in JavaScript to a button:
<input type="button" onclick="javascriptFunction()">
You can read more about ajax here:

I have a basic map and it is set up to take user (no need to sign up, just click and add details, then submit) input, it is just a plain text field. I know I need to set-up a php to store the new data as people enter it but I am a little lost. I searched but did not see an Q&A already, if it exists a redirect would be great. Thanks in advance!
Here is the page if you'de like to see the source, very basic. http://www.nextepisodepgh.org/worldartproject.html
Once the user has clicked on the button you need to do a post back of the form (either directly or indirectly via ajax) to your php page. Your php would simple just grabbed the get or post variable and save it to the database.
I want to do a search with pagination, but I don't know how to 'store' the data in the $_POST array, should I do it with sessions?

If you are doing a search, you are trying to GET data from the server, and not send data to it -- which means you probably should use GET, and not POST.
Also, it would allow your users to bookmark the result pages (or send those links by e-mail, IM, ...), which is always nice ; and, also, use the back/forward buttons of the browser without getting an alert box, which is nice too ^^
(Oh, and, BTW, it would help solve your problem ;-) )
Yes, you can use sessions or hidden fields and even better GET method in your form.
It is possible to use both GET and POST in form, just add appropriate attribute method to form tag:
<form action="index.php?page=5" method="POST">
So the pager links are submit buttons while rest of the data is stored in hidden fields. But that's not a good way to do this because you cannot pass someone link (on IM for example) to your search results.
But the best way is to store somewhere POST input data (look here: http://www.symfony-project.org/plugins/, when you input your query once, it is stored and remembered so you dont need to fill form multiple times)
