[PHP] javascript cookie dissapears when adding session_start()
I've been working on a PHP/Javascript Cookie Notify (Including multiple language support). Now I have one small problem, when session_start() is not at the top, the cookie message works as it should be. Now I am trying to add session_start(); at the top, as this will load the current language file the visitor has set it to. But then the cookie message will not show. I've cleaned all my cookies, and still can't get it to work ... I've put up a small code on jsFiddle, but when session_start(); is at the top, it launches correctly in jsFiddle. which can be viewed (here). Does anyone know what i'm doing wrong? And would you be able to explain me what I am doing wrong? Thanks

You see, PHP has a difficult time detecting IF Javascript is turned ON in the client's browser because PHP is history by the time the browser does anything, including running Javascript. Thanks, Tedd. That's how I suspected things to be. However, the list was very quiet, I might have missed something, and so I felt it couldn't hurt to ask. TBH I'd already done: echo pre; print_r ($_SERVER); echo /pre; and didn't spot anything there that I thought would give me the info I sought - but then I don't know the purpose of every element of that array and $_SERVER is not the only superglobal! As Yogi Berra once said; It's always hard to predict things especially when it deals with the future. However, once the browser has requested a transfer via HTTP that request is in the past and that request is where stuff that lets you know some of the browser's capabilities (e.g. HTTP_ACCEPT) comes from. So it would be possible by a similar mechanism for a browser to tell your script whether or not Javascript (or any other language for that) is available. However, there are two ways to kind-of doing it: Way 1 -- I place an element in html that is hidden from the user's view via css (display:none) and if Javascript is ON then Javascript changes the css so that the element is shown to the user (display:block). Here's an example: This is the reverse of part of what I've done for the page in question. I had a tabbed interface similar to: div id=sect01 style=display:block; [stuff] /div div id=sect02 style=display:none;visibility:hidden; [stuff] /div ... However, the second div must be visible if JS isn't available otherwise the user can't access that section. So I've changed the style of the second and subsequent divs to display:block and then used an onLoad routine to change the .style.display and .style.visibility attributes of the second and subsequent divs to none and hidden respectively so that those who have JS get the full DHTML. Now I also using AJAX on that page. However, I can use the fact that the trigger events aren't handled if JS isn't available to just retrieve what's actually needed at the time via AJAX if JS is available or submit the full form if it's not. Of course, that complicates things in the PHP on the server as the script then has to handle both interim and final form submission. FWIW, it's possible to detect whether or not Javascript is available, but not AFAICT at 'first contact' because you need the 'first contact' page to do something to prove that JS is available, from which you can assume that JS is not should that something not be done. For example, you can make the link to a page into a form submission - e.g: form name='jstest' action='myscript.php' method='post' input type='hidden' name='wehavejs' value=1 /form a href='myscript.php' onClick=document.forms['jstest'].submit();return(false); Click Here/a The form is submitted if the browser has JS and so the hidden input field is posted. However, if the browser doesn't have JS the default behaviour occurs when the link is clicked and so the field is not posted. Hence we can use isset($_POST['wehavejs']) to determine whether or not the browser has JS capability.

Cheers, tedd -- --- http://sperling.com/ I'm not sure if my earlier reply got through, but here it is again (or at least the general gist of it) There are ways you can detect if a browser is *capable* of running Javascript using $_SERVER['HTTP_USER_AGENT'] and an up-to-date browscap.ini file. This will allow you to check if the browser indicated by the user agent. However, there are caveats to this approach: * A browser might be sending the wrong user agent string, there are plenty of plugins which do this * A browser might be capable of running Javascript but might have it turned off or otherwise blocked * Filtering may be going on by a proxy server or firewall that strips out Javascript (sounds stupid but happens in paranoid businesses) Like everyone has mentioned thus far, it's better to use progressive enhancement or try to avoid relying on Javascript at all. Even a website as complex as Facebook allows users to go on it without needing a browser that runs Javascript. Something as complex as Google Docs has a very clear need for Javascript though, so you wouldn't expect that to work without it. Lastly, if you're creating the website for a government or business, you really need to make it work without Javascript, as a lot of countries make it illegal to discriminate against a disability, which you would be doing if you made a site that was unusable without Javascript. After all, there are many speech and Braille browsers out there that can't take advantage of Javascript, and a lot of Javascript apps which require mouse interaction to run (mouseover/hover events, etc) -- Thanks, Ash http://www.ashleysheridan.co.uk

I got your info the first time around but didn't respond directly to you as Tedd made similar comments and I'd responded to his post. Like everyone has mentioned thus far, it's better to use progressive enhancement or try to avoid relying on Javascript at all. Even a website as complex as Facebook allows users to go on it without needing a browser that runs Javascript. Something as complex as Google Docs has a very clear need for Javascript though, so you wouldn't expect that to work without it. In my case, one of the controls I'm considering is a tiled map with up to 16 tiles. This is on a page with four tabbed sections that takes several seconds to load at broadband speeds. Also, the nature of the site means that people may need to access it and use this form while connected via mobile broadband or even GSM; connection media that are usually both slow and paid for per unit of data transfer. I need to record in hidden input fields the location of where a user clicks on the map and also echo that click back in the form of a marker overlaid on the clicked tile. Using AJAX, I can update just the two fields plus one image. Without Javascript, the extra bandwidth needed to unnecessarily download the entire page multiple times will cost my users both time and money. So while I must ensure the site works without Javascript, I really need the optimisation that JS brings. Lastly, if you're creating the website for a government or business, you really need to make it work without Javascript, as a lot of countries make it illegal to discriminate against a disability, which you would be doing if you made a site that was unusable without Javascript. After all, there are many speech and Braille browsers out there that can't take advantage of Javascript, and a lot of Javascript apps which require mouse interaction to run (mouseover/hover events, etc) AIUI, a lot of countries (mine included) make it unlawful to knowingly discriminate against the disabled. However, The Disability Discrimination Act requires only that reasonable steps be taken to avoid discrimination ... and making stuff accessible to the disabled at considerable inconvenience and/or expense to everyone else is not considered reasonable. Now where I can, I'll produce stuff that is enhanced by images, colour, JS etc. but will still be usable in Lynx. However, some stuff (e.g. mapping) won't work without graphics and so is inherently unavailable to the visually impaired. It makes no sense whatever to try to make such content work in speech and Braille browsers. Thus making a site that's unusable without Javascript doesn't necessarily constitute unlawful discrimination! -- Geoff -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I suspect the short answer to this is No, but since the list is quiet I'll ask anyway: Q: Is it possible to check whether Javascript is available on the client without using client-side Javascript to create a form and hence pass a variable that will only be set if Javascript is available on the client? Is there something in $_SERVER etc. that can provide this info? Geoff: To answer your question in a new thread.

If Javascript is OFF then nothing happens. Way 3 -- another way is to use unobtrusive Javascript -- here's an example I did for my students: http://www.webbytedd.com/aa/add-onclick-button/index.php If Javascript is OFF, then the Add Another Record button is not seen by the user -- because it's not in the html. However, if JavaScript is turned on, then the Add Another Record button is shown and becomes available as another option via DOM scripting. That's called unobtrusive Javascript. Try it! Now that doesn't mean that JavaScript can't call PHP, because it can -- look here: http://webbytedd.com/b/timed-php/ and here: http://webbytedd.com/a/ajax-site/ Those are examples of JavaScript running PHP scripts.

Here's the form:
http://php1.net/a/insecure-form/index.php
It was a simple working example of JavaScript Injection. But it no longer
works and I want to find out why. The most popular reason thus far is
Browsers have changed, but I'm not sure as to what did change.
Look at the post-processing source --- note the slashes. Apply
stripslashes() to the output on the PHP side and all should be right
again with the world.

Sorry -- I'm not making myself clear.
The form as-is produced a javascript alert() and now it doesn't.
It doesn't make any difference if I use stripslashes() or not, it
still will NOT produce a javascript alert as it used to do.
Seriously, try this:
?php
$insecure = $_POST['insecure'];
//$insecure = stripslashes($insecure);
?

p
Enter (cut/paste the red) br/span class=red lt;script
alert(Evil Code); lt;/script/spanbr/ in the field below
and see what happens. The red is javascript code.
/p
form method=post action=index.php
p
Field: input type=text size=60 name=insecure
/p
p
input type=submit value=Submit Post
/p
/form
?php
if ($insecure != null)
{
echo(pThis is what you entered:/p);
echo(Input: $insecure);
echo(br);
$insecure = htmlentities($insecure);
echo(Input after htmlentites: $insecure);
echo(br);
}
?
?php include('../includes/footer.php'); ?
You can un-comment the stripslashes() function and it will still not
produce a javascript alert.

Looks like some form of variable tainting. There was a proposal and a patch a
while back, but all it did was emit a warning. I've looked at the PHP5
changelog to see if this was added but can't find any reference to it being
merged in.
This is not a browser change because it's happening before the browser sees the
response (try it with curl).

[PHP] Javascript question
Before some of you newbies feel like being heroes and jump all over me:
I KNOW THIS IS A PHP-RELATED LIST. IF YOU DON'T LIKE MY QUESTION, DON'T
ANSWER IT.
Now that that's out of the way... I have a Javascript question (and
maybe a Browser/DOM question) for you folks. I'm not sure this is
anything they teach you in any online/in-seat/self-taught Javascript
course that I've ever seen before, so I figured I would bring it here.
My boss asked me if I knew of a tool that would change the !DOCTYPE of
a page on-the-fly to test validation in different schemes (i.e., XHTML
Strict, Transitional, Loose, etc.). After a bit of looking around, this
is the solution I came up with (as a bookmarklet):
javascript:document.write('!DOCTYPE html PUBLIC -//W3C//DTD XHTML 1.0
Strict//EN http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd;' +
document.getElementsByTagName('html')[0].innerHTML);
However, I'm not sure it will fire any validation events, since
technically the page has already been loaded (Javascript is just adding
more text). I fear the case will be the same if the current page's
source is sent to a new browser window.
I'm not asking for any coding suggestions, necessarily--just curious as
to whether or not anyone knew if this will invoke browser validation
events or not. Comments and questions are more than welcome, though. :)
Cheers!

Can't you do it via PHP using a GET parameter? Seems more likely to work
properly since it requires the page be reloaded on a fresh slate. While
at the same time, it will easily jump through the doctypes that the
server deems suitable given the parameter

Absolutely. However, requiring a server-side script was something I was
hoping to avoid. It may be useful as an intranet utility somewhere down
the road, but a bookmarklet was what I was shooting for for this first
test.

[PHP] PHP Javascript header
Hello there,
Kind of newbie to PHP and javascript... I have this problem:
I want to pass a javascript variable to a PHP code.
I am inside a javascript function that is creating HTML elements
dynamically. After creating a select tag, I want to populate it with a
list of variable names from $_SESSION['subgroupcolumn'] .
Here is part of the code:
.
.
.
location.href=subgroup.php?m= + m;
var linner= for ($c=1; $c $_SESSION['rows']; $c++){ echo( 'option
value=' . $c . '' . $_SESSION['subgroupcolumn'][$c][0] . '/option\n' );
} ;
document.getElementById(selectedSubsetText + hitcounter).innerHTML = linner
;
.
.
.
Since we cannot pass a javascript var to PHP directly, I am redirecting to
subgroup.php and sending the variable (m) and getting it there using a
$_GET. Now the question:
In subgroup.php, after I get the variable m, I create the
$_SESSION['subgroupcolumn'] array then I redirect to the initial page.
Obviously it's not working because the code after
location.href=subgroup.php?m= + m; is not executing after coming back to
the initial page
How do I make it to continue executing the javascript code?
I hope it's clear...
Thanks for your help.

The problem is that you are changing the location of the page and then
chaning the location back. Really you need an AJAX call using
XMLHttpRequest. There are probably easier examples, but here is one:

[PHP] table mixing PHP, javascript, ajax and CSS
Hi, i'm currently working on some project which needs in several pages, a table to display query results...till now nothing special. however, in order to not create several time the table and features i've decided to create my own templates including PHP classes, CSS and javascript. this table class should have filter, colors schemes, multi selection and header/paging header. I would like to know what are your suggestions, recommendations or tips to have something easy to deploy and upgrade ? i was thinking to have a common (framework) base : a simple html file having 3 divs, each div receiving a particular php file (header, pagin, or the table itself) header, paging or table PHP files could be located in some folder being different for each template... main changes in templates are usually for the table it self (in terms of columns amount, of presented data record,...) basically my structure is the following one: /folder_to_include_by_user_in_his_development_environment /templates /template1 pager.php table.php /template2 pager.php table.php header.php frame.php /class table_class.php helping_classes.php ... /js_and_ajax function.js the user will have only to run a js function which will include the frame.php file into his own webpage with the template given as parameter. thx for any suggestion. -- Alain --- Windows XP x64 SP2 / Fedora 10 KDE 4.2 PostgreSQL 8.3.5 / MS SQL server 2005 Apache 2.2.10 PHP 5.2.6 C# 2005-2008

True, you can access an input named myInput in a form named myForm
by simply writing:
document.myForm.myInput.value = Hello!;
BUT... for CSS, it's also quite easy to reference something by name:

address the form elements using only the names (in fact, it's easier
than via the ids as there's a short syntax for it!).
CSS and the DOM, however, use the ids as primary identifier, so use
of
either of those may demand the presence of ids.
8 snip!
True, you can access an input named myInput in a form named myForm
by
simply writing:
document.myForm.myInput.value = Hello!;
BUT... for CSS, it's also quite easy to reference something by name:
[name=myElement]
{
color: blue;
font-size: 10pt;
}
Well, true -- hence the qualifiers in *primary* identifier and *may*
demand!

[PHP] JavaScript and PHP
Hi,
I have this HTML/JS page that switches images clicking on the radio
buttons and call template.php with the image ID as parameter:
http://portulan-online.net/einstein.html
Now, I need to make it a PHP page, because it is going to receive a
parameter from the URL that calls it and pass it as is to template.php
So, einstein.php will be called with a parameter (satellite):
http://portulan-online.net/einstein.php?satellite=123
After that, in einstein.php, I do:
$satellite = $_REQUEST['satellite'];
Next thing, I need the action in the JavaScript to be, for example:
http://portulan-online.net/template.php?id=3satellite=123
What I don't know is how to mix the PHP variable satellite with the
image ID here:
document.getElementById('image1').src =
http://portulan-online.net/einstein-; + ID + .png;
I've tried putting einstein.php all inside an echo, but the radio
buttons and the submit button stopped working.
Does anyone knows how to do this ?
Any help would be appreciated.
Warm Regards,
Mário Gamito

You could do that. Also, I'd suggest using $_GET instead of $_REQUEST.
Request works,b ut it is very broad. $_GET is more specific/secure.

My code to start, looks like this:
?php include('../header.php') ?
h1 Hi /h1
?php include('../footer.php') ?
From there I have a complete page -- from doctype to copyright, it's
all there and it validates.
If I need a javascript file locally, then I add it to the local
working directory by naming the file a.js. Likewise, if I need an
additional css file, then I name it a.css and it's also included in
the call.
However, if I don't need those files, then none are included in my
local working directory and attempts to load those files will fail --
however -- it doesn't matter if an attempt to load fails or not as
long as the files are not needed.
I think that's kind of clever, but I like Rocky and Bullwinkle as well.

I think that's kind of clever, but I like Rocky and Bullwinkle as well.
I don't use a script to find my JavaScript files and CSS but I do
something similar to your includes for header and footer. The difference
being that my template engine will pull them in at compile time and not
at run-time. A lot of static content is pulled in this way and relocated
using compile-time accumulators. Then I use run-time accumulators to
flush content at run-time into the appropriate areas if necessary. This
allows me to create a layout that is compiled once at compile time but
with flush hooks for run-time. For instance for simplicity I use the
following tag in the head area to set up JavaScript:
jinn:javaScriptSystem/
This is the same as doing the following manually:
jinn:accumulatorFlush name=javaScriptTags/
jinn:accumulatorFlush name=javaScriptTags dynamic=true/
jinn:javaScript
jinn:accumulatorFlush name=javaScript/
jinn:accumulatorFlush name=javaScript dynamic=true/
function javaScriptOnLoad()
{
jinn:accumulatorFlush name=javaScriptOnLoad/
jinn:accumulatorFlush name=javaScriptOnLoad dynamic=true/
}
/jinn:javaScript
-
The body tag will have an onload=javaScriptOnLoad(). Then in a content
file I can add the following:
jinn:accumulate name=javaScriptOnLoad
// some javascript code to modify the DOM
/jinn:accumulate
And it will get relocated at compile time to the location of the static
flush statement: jinn:accumulatorFlush name=javaScriptOnLoad/
Similarly within my code at run-time I can do the following:
$mAcc = $this-getServiceRef( 'accManager' );
$acc = $mAcc-getRef( 'javaScriptOnLoad' );
$acc-append
(
' // some javascript to modify the DOM '
)
And it will be get flushed into the content at the location of the
dynamic flush statement:
jinn:accumulatorFlush name=javaScriptOnLoad dynamic=true/
So all in all, it's very simple for me to put JavaScript (and any
content for that matter) anywhere I please. I often use it for layout
areas (such as left pane, right pane, etc), menus, visitor notices, etc.
BTW if you're wondering why I have a jinn:javaScript tag it's because
who wants to remember the following:

Generally, script blocks outside of the head are meant to be used for
routines that run as the page is loading. For example, one might have
some JS that creates some block of HTML or something. Or one might have
a JS block at the very end of the page that is meant to run once the
page has (almost) completed loading. Why people do this, i'm not sure.
Personally, i think script blocks belong in the head. If you have some
function that needs to run at page load, there's the onload handler for
that.
In your case, it looks like that function could be placed pretty much
anywhere, as it can only be called once the page has loaded, anyway. Is
your problem that you can't change the head of the page (to include that
function) for some reason? In any case, go ahead and put it in the body.

In head - whenever possible
In body - whenever else
It's not incorrect to have JS in the body, but it sure makes it more
difficult to see what's happening.

Actually, I didn't want to answer this, but you're talking shit here ;)
Javascript needs to be initialised before it can be used.
So, if you have a function bodyload(), and you call it from body
onload=bodyload();, you need to place it inside head, as it isn't
loaded if you put it in body.
Some browsers will still run the javascript code, however it is not recommended.

Re: [PHP] javascript in head or in body ?
Ok, you got the obligatory 'wrong list' comments. It is the wrong list, but for the sake of public completeness... how about an answer to the question. You can put it anywhere but a couple of considerations: 1. I believe if you put it AFTER where the JS functions defined in that block are called, it may try to call the functions before the functions appear. So close to the top is always good. I could be wrong on this, but there was some kind of condition along those lines and I think it was with JS and positioning. 2. Non JS compliant browsers. If you put it in the body, they're likely to ignore the script tags and just blatantly display the JS as if it was meant for output. This can be mitigated by using HTML comment blocks around the JS. Since they're different than JS comment blocks, it won't interfere with the JS. But putting your script in the head block should also prevent it from being displayed. 3. If you're executing JS in order to output something, you're going to need to put it whereever in your HTML you'll need the output. If you're just defining functions to be called later, then you can put it whereever (probably above where you're calling the functions.. see #1). The only things we don't put in the head for script blocks is a popup calendar thing that the old developer installed and our users seem to like. Part of it's requirements is a script tag that includes some JS and HTML where you want the popup calendar to appear. Could probably be streamlined, but works well enough and doesn't look too ugly so why make more work for ourselves until we do the full re-design (2035?) -TG = = = Original message = = = Are there any rules when to include javascript in head or in body ?

You can still have it in the head and use javascript to target specific content to a tag with an ID. In fact, I'd say that's a better option when used in conjunction with onload() since you can be certain all of your libraries are loaded. Additionally it allows you to place default content in the event that your visitor doesn't have JavaScript enabled. Cheers, Rob. -- ...

Re: [PHP] Javascript and PHP interaction
What you *COULD* do is this:
Use .htaccess to force your .css files to *really* be PHP files:
Files ~.css
ForceType application/x-httpd-php
/Files
[NOTE: Depending on your server configuration, the
application/x-httpd-php part could be *ANYTHING* the sysadmin felt was
appropriate...]
Inside your CSS, you now have the full-blown power of PHP to output
whatever you think is right for the CSS.
But you'll need to tell the browser that this *IS* CSS output, so
you'll need:
?php
header(Content-type: text/css);
?
at the very tip-top.
Note that browsers can cache the CSS, so you'll want to add more
headers to stop that, probably, or have a random value in the LINK tag
in your HTML document.

I think you can not do it with PHP.
But you can do it with javascript. you have to read the offsetWidth
property of the object, then set it's style.width like
if (document.getElementById('whatever').offsetWidth 300) {
document.getElementById('whatever').style.width = 300;
}
hope that helps

Re: [PHP] Javascript and $_POST
There is nothing wrong with the way you want to submit this form.
Although it's JS :) The sample code you posted was broken in some ways...
missing document. in JS en missing input field to check.
This sample works fine ...
test.html
script language=JavaScript
function checkForm() {
if (document.inputForm.cc_phone_number.value == ) {
alert( Please enter a phone number. );
document.inputForm.cc_phone_number.focus();
return;

Think some other code or JS errors might stop the form from sending data.

}
}

Re: [PHP] Javascript and $_POST
Don't see how this can pass the check without document.
if (inputForm.cc_phone_number.value == ) {
alert( Please enter a phone number. );
inputForm.cc_phone_number.focus();
return;
}
Comming to this check already gives an error.
Maybe ask on some Javascript list.
P.s. reply to the list please.

You guys are going to kill me! I found my problemand it's one of those
What the hell were you thinking issues.
Within my form was a button but I stupidly made it a submit when I created
it and therefore the javascript check for submit was finding my button first
and dumping the error.
So, in summary:
function checkForm( )
{
document.FormName.submit();
}
*DOES *work and will pass your $_POST values between pages as long as you

I have a form that uses Javascript to validate form field entries, and if
they are incorrect it returns an error to the user.
After the Javascript processing is complete, it submits the form to my save
page. However it seems that once the processing is complete and it passes to
the save page, none of my $_POST variables are being passed.
Is this normal, or is there a work around for it?
My Javascript has multiple checks. Below is a very condensed version:
script language=JavaScript
function checkForm() {
if (inputForm.cc_phone_number.value == ) {
alert( Please enter a phone number. );
inputForm.cc_phone_number.focus();
return;
}
document.Submit.submit();
}
/script
And this is my Save option at the bottom of my page
form name=Submit action=save.php method=post
enctype=multipart/form-data
table align=center border=0 cellpadding=0 cellspacing=0
width=680
tr
td width=64 align=lefta href=javascript:checkForm()
title=SaveSave/a/td
/tr
/table
/form
When I click on save, it does go thru all the checks correctly and prompts
to enter info if anything is left out. It then passes me to the
save.phppage as it should, but all of my $_POST('X') values come
in blank.

From the looks of it, you have two forms - one called Submit and one
called inputForm. You need to submit the inputForm for the values to be
passed to the processing page.
document.inputForm.submit();

Maybe you just condensed-out the inputs, but if your inputs aren't within the form, they won't be submitted. E.g. if you have: form id=dataForm input ... / input ... / /form form id=submitForm ... /form If you submit submitForm, nothing will get posted. You want to post dataForm in the above example. (Or whatever inputForm happens to be in your example.) jon -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
