Create/Update Php Session With Javascript
Dec 15, 2005
I am trying to create/update a Php Session with Javascript to confirm
if users have Javascript enabled.
My first thought was to create a Javascript that writes a script tag
referencing a php page, which sets a $_SESSION variable.
javascript.js:
<script type="text/javascript">
<!--//
document.write('<s'+'cript type="text/javascript"
src="javascript.php"></s'+'cript>');
//-->
</script>
javascript.php:
<?php
session_start();
$_SESSION['javascript'] = 'enabled'
?>
I can see that both the javascript.js and javascipt.php files are
executing from the web logs, but when I try to query the
$_SESSION['javascript'] variable from another page $_SESSION is empty.
Is it possible to create/update a Php Session with Javascript?
Might it be done using URLEncoded URL, Javascript XMLHttpRequest, or
something of the like?

I currently have a form that asks for certain info. When the user enters and then submits it, a javascript script sends the info to a php form and then php does its thing. While doing its thing, php tries to change a php session. I am wondering if there is a way to change the php session, and have it take effect on the user end without a refresh. So if the user has a session for their name (Bob), then goes to this form and changes it to Joe, then session the user has will be changed from Bob to Joe without the page reloading. Is this possible?

I´m using this code to avoid the "click to activate" a flash file, it does work, but it seems like the browser is still loading something (not flash), it is related to this code, since removing it, the browser stops loading.
objects = document.getElementsByTagName("object");
for (var i = 0; i < objects.length; i++)
{
objects[i].outerHTML = objects[i].outerHTML;
}

I'm trying to create an object that will update itself at a set interval, but I'm having a scope issue when using the "setInterval" or "setTimeout" function.
[Code]...
But I get the same result. Ultimately, I'd rather have the setTimeout (or setInterval) to be within the object, so that each instance of the object will fire the update on itself. I had a similar issue in this thread but I can't seem to figure out how to adapt it for this instance.

What I have got is a form that a user has to fill out and submit (when validated all variables are stored in a session and emailed after multiple forms are completed), currently I have radio buttons, text boxes and a combo box/ drop down list (for location). All parts are working fine and validating fine. My problem is to do with the combo box//ddl. I have successfully validated the ddl so the user must select a location onsubmit and it is added to session and passed fine.At the moment the ddl only has cities or towns in it however as I would like to include different states and possibly different countries I need a code that validates the state first and then only gives the cities/towns that are in that state (otherwise my ddl would be to large). I can do this with links however I can't seem to do it in a form.

I'm doing an ajax call to a remote php file... it returns a value fine,
and even enters a value into a text field on my form. The problem is,
right after the function call to the ajax function, I do an alert of
what the field value is, and it doesn't recognize the field value has
been changed. Two caveats:
1 - It will recognize the last call's change
(if I run it a 2nd time, it'll see the 1st call changes)
onBlur="ajaxCall(document.form1);alert(document.form1.ajax Field.value);">
2 - It'll recognize the current call's change if I set a 2 second
timeout
onBlur="ajaxCall(document.form1);setTimeout('checkFields(d ocument.form1)',2000);">
It seems, although I can see the text field getting updated,
programmatically speaking, it isn't reflecting it until everything is
done... including any alerts and such.
It's weird seeing the empty alert popup, when I can see the value in
the text field underneath it.

I am trying to update all Select boxes on a page dynamically using
javascript, I simple want to change the selected item in each select
box when a tick box is pressed on the page. Each Select box is named
in the same convention ie. ddl_DeliveryStatus_ and then the recordID
and contains the same options in the same order. The number of select
boxes changes every time the page is loaded as this is all built using
ASP linked to a database.
I am hoping there is an array or collection or something similar I can
simply reference to do this, but an struggling to find the answer.

I know that IE6's support for CSS is well... hmmm... lets just say not very good, however I was wondering if style declarations can be added at run time, via JS?
e.g.
Can I create a new rule?

I have a situation where I'm displaying some information in a table on
a web page. I've given the user the ability to make several different
"queries" and show different sub-sets of the data.
I would like to add a button to the page that would allow the user to
create an .XLS file that would contain the current contents of the
table. I realize that I could create it on the server and allow him to
download it but I'd rather let him create it right there on his
machine. Is it possible to have a script that can do such a thing?

I don't know the problem with IE6. I have tried three methods, and
they all failed. I eliminated the use of mootools' framework in method
3. MooTools is not the problem. Because the table is created but is
not showing up. I have checked that with IE developper toolbar. Code:

is there a way to create iframes using cookies and javascript? What i need to do is to have a way to create a cookie on page one, and use the info on page two to create the iframe.Users will see a list of "external links", once they click on a link, they will be redirected to a page that will generate a iframe of the chosen link.My guess is that if there is a way, it must need to use cookies to store the info (url) to get used by the script that will create the iframe on the page that will be used to show all iframes.

Now to my question: I've created a dynamic table sorting script in JavaScript.
It allows you to sort any by any column ascending or descending and even remove options (kinda like Excel in a way).
It uses (as far as I know and I've tried to keep it) 100% standards compliant code.
Not surprisingly, it doesn't work *at all* in Internet Explorer yet it works *perfectly* in Firefox and Opera.
The funny thing is that IE doesn't throw any error messages--just a blank page.
Here is the page in question (please be sure to enable JavaScript to see the effect).
Any ideas?

I'm trying to output an HTML page from a simple XML file, but I need to offer this as a service from a website, so users can browse and find the XML file on their local hard drives, and then generate an HTML page.
I think there are some security issues with HTTP not being able to access local files (ie. C: emp.xml) because it doesn't work when I browse to a local file from the website (files on servers work fine). Is there any other way to pass an XML file from local to a website?
I'm using the following javascript to load the XML file.
var xmlDoc=new ActiveXObject("Microsoft.XMLDOM")
xmlDoc.async="false"
xmlDoc.load(filepath)

I am having difficulty on maintaining session when using ajax.
I first load a page with a session genterated. But since AJAX is a
client side activity where I sent an AJAX request to an url without any session
info. Of course, the server will create a new session. Even though I
can write the session id into the first page where I made ajax calls, it is not a secure way...
How do people deal with this problem?

I'm just beginning with JavaScript (and Ajax). My loginscript now works with Ajax - that is; the script is sending a request to the servers PHP script to check username and password, but I wonder what that script should return - and how to use that response. Either XML or pure text: The response is now "false" if the user couldn't log in for some reason, and the users ID and real name if the login went well...
But then the problem: if login IS ok - so that the users ID and real name is returned from the serverscript - I would like to store those variables in a session variable ($_SESSION in PHP). How do I get those variables back to the client script from JavaScript?
