I have used this page http://www.binarytides.com/blog/php-redirect-go-back-to-previous-page/
to go back
but from
http://page.co/test.php?item=26
I post something to post.php and then call the php Go back function but I go back to
http://page.co/test.php
losing the argument path, any idea?
In Your form fill in the query string to the action attribute, like this:
<form action="?item=26" name="myform">
...
</form>
and after the submission Your HTTP_REFERER will contain this query string so redirect to it will be successfull...
EDIT: If the form is on the page post.php, it is enough to use action="?item=26" - of course You can and should use PHP to write down the number/ID of item from whenever it may come...
Lets say Your item ID is stored in the variable $item_id - then Your action will look like this: action="?item=<?php echo $item_id; ?>".
You should use sessions for stuff like this. Set a session when posting the data and you're set.

I've got a php script which builds a html table via echoing data, But i want to add a link onto one of the values and pass that value to the next page.
<td><a href='redirect.php'><?php $_SESSION['WR'] = $row['WorkOrdRef'];echo $row['WorkOrdRef'];?></a></td>
is the line in question but this will only pass the last value added to the table.
Oh, it doesnt work like this. the php code gets executed no matter if you click the link.
I guess the easiest way to do this is to pass it as a get parameter.
html page:
<?=$cellContent?>
redirect.php:
$clickedcell = $_GET['clickedcell']
now the $clickedcell will have the data from the previous page about what cell did the user click.
If you want to use session for some reason, you still have to pass it with GET or POST and store it after the user clicks.
hopefully this is understandable and good luck with your project.
you can change the session by get method also it is possible building by javascript
in the same page add this
if(isset($_GET["clicked"])){
$_SESSION['WR'] = $row['WorkOrdRef'];
$redirect'<META HTTP-EQUIV="REFRESH" CONTENT="0;URL='.$adres.'/"> ';
return $redirect;
}
and then change your url
<td><?php echo $row['WorkOrdRef'];?></td>
I am working on a project where i need to access clean URL's always i.e no parameters can be passed in the URL for getting values on another page.
Can anyone please suggest an alternative other than 'Form Submit' method.
Thanks In Advance.
Use $_SESSION for this purpose.
Using $_SESSION you can use variable in multiple pages wherever you want.
// assigning variable
$_SESSION['name']="variable";
//retrieving
echo $_SESSION['name'];
write session_start() at the top of page wherever you want $_SESSION variable
For Clean URL's i prefer you may use HTTP POST Method. Hope that helps.
<form name="frmApp" method="POST" action="/action.php">
</form>
Else, you can use AJAX with jQuery to submit the values to another page.
$.ajax({url:"action.php",success:function(result){
$("div").html(result);
}});
Check out w3schools to get started with AJAX : http://www.w3schools.com/jquery/jquery_ajax.asp
No support for SESSION since i don't like writing php code inside my web page.
Sessions can help, or ajax call.
for using clean url you can use post method in form
<form name='' method='POST' action=''>
You can try mapping resources to the url.
Suppose you want to get mailing address of a customer then you can write.
http://[baseurl]/[customerId]/mailingaddress.

I'm trying to store the redirect URL for use a few pages later but I'm having trouble figuring out how to get it from one place to another.
Usually I'd just pass a variable thru the URL, but since my redirect URL contains URL variables itself, this doesn't exactly work.
To give you a better idea of what I'm trying to do, here's the structure.
PAGE 1: User can click a link to add content on PAGE 2
PAGE 2: User enters text. Submitting the form on this page calls "formsubmit.php" where the MySQL data entries are handled. At the end of this I need to redirect the user to PAGE 1 again. The redirect URL needs to exactly match what was originally on PAGE 1
Does anyone have any suggestions on how to go about this?
You should use $_SESSION to store the variable in session memory. As far as specifics go with how to handle this in particular, you should be able to figure it out (store the variable, check if it exists later, if so redirect etc etc) but $_SESSION is going to be much more efficient / less messy than trying to pass things back and forth in query strings.
To declare a session variable you would do something like this:
$_SESSION['redirUrl'] = "http://www.lolthisisaurl.com/lolagain";
And then to reference it you just do
$theUrl = $_SESSION['redirUrl'];
Here is some material to get you started: http://php.net/manual/en/reserved.variables.session.php
I would recommend either using session variables, or storing the redirect url in a hidden form parameter. Session variables are pretty simple; just initialize the session (once, at the top of each page), and then assign variables to the $_SESSION global var:
<?php
session_start();
...
$_SESSION['redirect_url'] = whatever.com;
...
Hidden form parameters work by sending the data from page to page as form data. On the backend, you would add code that would put the URL to be stored in a form variable:
<input type='hidden' name='redirect_url' value='<?php echo $redirect_url; ?>';
On each page, you can take the URL out of the $_POST or $_GET variable (whichever is appropriate) and insert it into a hidden form in the next page.
You can use urlencode and urldecode to pass a string that contains elements that would otherwise break a url in a url query.
I can see two possible solutions :
get the previous page from document.referrer ([edit] find more info on this SO thread : getting last page URL from history object - cross browser?)
store the previous url via a session variable ([edit] MoarCodePlz pointed this out in his answer)

You can add this hidden field in to your form:
<input type="hidden" name="referer" value="<?php echo $_SERVER['HTTP_REFERER']; ?>">
Then use header() to redirect to this page:
header('Location: '. $_POST['referer']);
I've never really thought about this, but it helps with some security of something I'm currently working on. Is it possible to submit GET data without an actual input field, and instead just getting it from the URL?
If so, how would I go about doing this? It kind of makes sense that it should be possible, but at the same time it makes no sense at all.
Perhaps I've been awake too long and need some rest. But I'd like to finish this project a bit more first, so any help you can offer would be appreciated. Thanks
Yes. If you add some query-string to yourl url, you can obtain that in php using $_GET without form submitting.
Going to this URL adress http://yoururl/test.php?foo=bar cause echoing foo (if there will be no foo query string, you'll get warning).
# test.php
echo $_GET['foo'] # => bar
Is this what you mean?
Link
// page.php
echo $_GET['type']; // foobar
This is what I understand of your question:
You have a <form method="get" action="foo.php">-like tag on your page
You have a series of <input type="text" name="bar"/> in your page
You want to pass additional GET parameters that are not based on an input from the form
If so, it is possible, but I hardly see how it could help with security. Input from a client cannot be trusted, so even if you hardcode the GET value, you have to check it serverside against SQL injection, HTML injection/XSS, and whatnot.
You have two ways:
Use a hidden input: <input type="hidden" name="myHiddenGetValue" value="foobar"/>
Add the GET parameter to the form action: <form method="get" action="foo.php?myHardcodedGetValue=foobar">
If what you meant is that you want to have a GET request without a form, you just need to pass all the GET parameters to the href of a link:
Click here!
Yes it's possible. Just append the GET data to the link.
For example:
<a href="main.htm?testGet=1&pageNo=54>Test</a>
You can also use Javascript to build the url.
If you happen to be using jQuery and want to build the GET data dynamically you can do this:
var getParams = { testGet:1, pageNo:54 };
$(".myLink").attr("href", url + "?" + $.param(getParams));
