Passing Variables Between Web Pages
Jan 19, 2004
I am attempting to display info put into an array from an onClick() event in a different page - I have created different functions which populate an array with different info dependant on which link the visitor clicks ie HTML Code:
<a href="nextpage.htm" onClick="functiontopopulatearray()"> SELECT</a>
The function seems to work fine, however when the next page loads and I attempt to access the array elements they are now undefined - both pages are linked to the same JS document.

On the response to my first post, "Passing Variables", I see how to use the cookies. How would I use session variables? I thought you could not access them via jquery.

I have an HTML page which loads another page inside an IFrame. Each of the two pages has its own javascript code.
I would like to be able to define one global variable which will be accessed from functions in both scripts. The variable must be single. That means that if a script in one of the pages changes it, the change will be seen by the scripts in the other page.

I'm using Klaus Hartl's"jQuery Cookie plugin" to send variables between pages with Jquery. Works like a smile in Chrome BUT messes everything up (reloads the whole page into a one of it's div's) in FireFox and (of course) IE... Can this be accomplished without using cookies?
The script in the receiving page looks like this:

For some reason, I am using document.referrer in a PHP script that is called as a JavaScript script. The problem is that I need to pass the value of document.referrer to a PHP variable (in the same file) in order to add it to the database. How can I do that?

This probably seems pretty trivial to you experts but I just don't know why it doesn't work and would like a nudge in the right direction please.I have a sllide and fade that works great - no problems. I am firing it with a function call from the HTML like so;<a href='#' onClick='sfade('#s1'); return false;>as you see I am passing the div to be faded(and slid) as a variable. Works great. The receiving function is:
var str='';
function sfade(str){
$(str).slideFadeToggle(1000);
[code]....

I'm creating dynamic buttons and forms for a website and would like the form hidden when it's corresponding button is clicked. However, when I pass button and form name variables to my JavaScript that hides the form, the variables are not being recognised unless I explicitly set them. (e.g 1 and 2 as seen below).
In a nutshell the onlick event doesn't seem to like PHP variables !

Don't know if this should be under JS or PHP... I have 2 different pages. On the first one, a table shows a list of items. Each has a button that when clicked opens another window with specific size attributes, hence the onClick event. The 2 PHP variables are computed and different for each item (each line).
Here is the line:
<input onClick="javascript:window.open('player_buy.php?send_role=<?=$data['ROLE']?>&send_price=<?=$send_price?>', '_blank', 'status=0,toolbar=0,scrollbars=0,location=no,statusbar=0,menubar=0,resizable=0,width=739,height=320, top=0,left=0')" class="button_sale" type="submit" value="> > >" name="submit">
Now of course, on the popup window, the URL will show .../player_buy.php?send_role=XXX&send_price=XXX
But the goal is to avoid that. So my question is: Is there a way to open such a popup window, pass these variables to it but in a way that it would not show in the URL?

I have a javascript function that receives the form name, field name and value and I want to be able to spit that data back to the originating form after doing some processing on the data.
The values are making it to the function perfectly, but when I try to return those values to the form, it tells me it's not a function. I know there's some syntax problem, but I'm just not sure where!
function doThis(one,two,three){
var myFormName = one;
var myFormField = two;
var myFormValue = three;
var goHere = myFormName + '.' + myFormField;
[Code]...

To formulate the problem simple i have two buttons with the onclick function:
I guess what im asking is how can you set a variable by one onclick function and then use it in any other function?

I have one page witih PHP where users will be answering a form for file upload. However, I need to give them the option to either upload a file or select one that is already uploaded.
In order for them to select a file that is already uploaded, they will use a pop up window to browse to the file and and select the a file with a radio button or submit button to select the file.
What i need to happen is when they press "select" they window needs to close and that file's url or relative path needs to fill in the "select uploaded file" with the path or url.
I"ll be using PHP in both form and popup for the file, but I cant do that with php without refreshing the page. Can javascript do this and how would I go about this.

A while back I was working on learning C++. However after finding out that making API's was too difficult I switched over to HTML and Javascript for a while to get it to do what I want without having to fry my brain on weird code statements.
Well now I've reached the barrier of being able to save data. For a while I've just had it to the point where the code I need is saved in a textarea and I copy and paste it in notepad. Then upon reentering I pull it out of Notepad and paste into the testarea.
Well enough with the bla bla bla. Is there a way I can use the <form method="post"> stuff to pass a variable to a C++ compiled program?
All I need to know is: 1) can I use <form method="post" action="SomeProg.exe"> and 2) what would the name of the posted variable be to use in my C++ code? As you can tell I running client-side so PHP and other server-side languages that WinXP don't support without special installation wont work.

How to pass (well more like bridge) session information to the client side from server side.
Right now, what I'm basically doing is echoing the userID and the username into a method in JavaScript tag at the bottom of every page.
The reason why I am doing this is simply for AJAX-related interactivity.
This is an example of what the code looks like:
Code:
A) It requires JavaScript code to be pasted within the HTML document (its non-external).
B) It requires the code to be echoed in EVERY PAGE.
C) A PHP Script or Class must maintain the responsibility of printing the session values.
D) The variable data cannot be accessed from any imported javascript files prior to where it was printed.
Now, I'm wondering about using Cookies. This would benefit me since I don't have to inject any ugly javascript code into the HTML output. I can also remove the PHP script that echoes the values and the changes will be purely handled in PHP (cookies can be updated!).
The only issue that's stopping me is simply security. Since cookies can be edited very easily on the client side, then the data can be changed. But then again so can the JavaScript (using a tool like Grease Monkey).
Once again, I am aware to never ever to trust the client side data without any validation; therefore using some sort of hash checksum, the cookie data can be compared to its PHP equivalents.

I've been workling seperately with PHP/ MySQL and am now trying to get things together with jQuery which I have so far only used with non-dynamic content. Here is the setting I am trying to achieve:
I have one php file that generates two different contents depending on the setting of a status-variable $ncs. If $nsc=0 the main page is loaded, showing an overview of all available news-articles. If $ncs=1 the content of a specific article is shown fully. The jQuery connected to each case differs. So i would like to pass the varible $ncs over to my jQuery script:
Code JavaScript:
I have checked that $ncs is not NULL on the rendered page. However after being passed to the jQuery script the variable is undefined. I have never connected PHP and jQuery so it is probably a general twist in my idea of how it works. I tried passing different variables and all are undefined in jQuery. What do I have to attend to when passing PHP-variables to jQuery?

I'm trying to pass multiple variables using a url on a Java function call.
the code I have that passes the 1 variable is:
function HandleChange() {
parent.CustomerIf.document.location.href="CustomerReturn.asp?id=" + varName.options[varName.selectedIndex].text;
}
which passes the chosen data (being loaded from a database) from a drop down box on an onchange event in asp script.
What I want to do is pass multiple variable via the above url script that the next page will get by the request.querystring method.
something like this:
function HandleChange() {
parent.CustomerIf.document.location.href="CustomerReturn.asp?id=" + varName.options[varName.selectedIndex].text + "address=" varAddress.value;
}

Basically, I have a window with an empty text field in. When I click on a link, another window appears on top of the first. (A pop up window.)
The popup window also has a text field in it. If I type "Test" in the popup window's text field and click "Submit", is there a way I can send that value to the empty text field in the first window?

We have a content management system that requires us to fill in 20 fields for metadata about a page. We store the metadata in a separate database for our records.
I'd like to be able to open a window with the data from our database, click a link, and have it fill in the form in the content management system (hosted by a different organization, so window.opener is out of the equation).
I tried this
<a href="#" onClick="window.open('http://www.google.com', 'Google'); window.Google.f.q.text.value='my name'">Enter my name in Google!</a>
In this example, I'd click a link that would open up Google, then pass the value "my name" to Google's search bar. Unfortunately for me, it didn't work.
Am I asking too much? I'd hate to have to rekey or copy/paste 20 fields worth of metadata each time I create a page.

At the moment I have this function, which passes variables to a php file with $_get
function savePath() {
//store title
pathTitle = 'pathTitle=' + document.getElementById("pathTitle").value;
//pathLength = getPathLength();
window.location.href = "save-path2.php?"+pathTitle;
}
but I need to use $_post
function savePath() {
//store title so we can use $_post
pathTitle = 'pathTitle=' + document.getElementById("pathTitle").value;
data = '<form action="save-path2.php" name="formData" method="post">
<input type="hidden" name="pathTitle" value="'+pathTitle+'" />
</form>'
document.formData.submit();
}
How would i automaticly submit the form?

I forget how to parse the variables passed on the URL like this:
<A HREF="http://www.mysite.com?bla="blahhh"" TARGET=_blank>http://www.mysite.com?bla="blahhh"</A>
How would I check this for a value and add some code to a page if it is equal to this value?

Im simply trying to make a dynamic searchbar so that the results pop up as someone write in the keywords. Problem 1 :When i pass foreign char types through jquery's $.ajax(); such as:
[code]....
they get translated to some weird characters when i try to compare them in the mysql database.javascript side:
Code:
$("#id_study4").keyup(function() {
var keyword = $("input[name=study4]").val();
var school_id = $("select[name=school4]").val();
[code]....
And the second problem is simply when i get he search results, i have the keyword emphasized with bold font weight, and text underline so that people can see. The problem here is that if i search with the keyword bach, then result becomes <b>bach</b>elor with all small letters when it should be <b>Bach<b/>elor. The way i have done this can be seen below:
Code:
str_ireplace($keyword, "<b>".$keyword."</b>", $study['study_name'])
