#7802 — passing values into javascript

<script type="text/javascript">AudioPlayer.embed("audioplayer_1",
{soundFile: "http://mroldies.net/mp3/[value1]-[value2].mp3"})</script>

Given this line of script which is from the wordpress standalone
audioplayer, how could I pass a value from page one to page two so that the
two values in brackets are replaced with the proper information?


http://mroldies.net/1960/all60.html

What I am looking at doing is, linking each song name to one php page.

So that I only have to have one line of code per artist.
Rather than having a single script per song.

I don't care to read your flames on the page showing an under construction
page for most of the links. I have it that way for a reason. Or any of your
other trite little flames that you do just to harass me with.

PHP runs on the server, and doesn't know anything about javascript 
(which runs on the client).  The only way PHP can "pass values" to 
javascript is to generate the data in the data which is sent to the client.

But since you're asking about how to do it in wordpress, I would highly 
recommend you ask din a wordpress support group.  They know their code 
better than anyone else, and will know better than anyone else what you 
have to do to get it to work in their environment.

Wordpress created the script to run outside of it's own format.
Had you bothered to look at the page given, you would see the script in
action. I do not have the fullblown Wordpress stuff on my site.

As PHP creates the html page, it would be, or should be, rather simple to
produce a line of code for that line of JS.
Such as 
Echo "<script>code</script>"

Yep.

Now all you have to do is work out how to get the values you want where 
you have "code".

Simples. Google "javascript variable assignment"

It's probably something like:

echo "<script type='text/javascript'>var jsvarname = {$phpvarname};</
script>\n";

If $phpvarname is a string, you'll need single or escaped double quotes 
round it, either of:

echo "<script type='text/javascript'>var jsvarname = '{$phpvarname}';</
script>\n";

echo "<script type='text/javascript'>var jsvarname = \"{$phpvarname}\";</
script>\n";

If You want to pass the value of a javascript variable from one page to a 
script on another page, then on the first page you need to put the 
variable value into a suitable post or get request (which is a javascript 
issue, not a php issue, so don't ask how to do it here), and then in the 
php you need to extract the value from the request, validate it, and then 
use it for $phpvariable.

How you get it into the post / get request using javascript is a 
javascript topic, not a php one. You might want to google something like 
"dynamically generating get request urls with javascript".

On the php side, you can check that a string in the $_POST or $_GET array 
matches the expected format using a regex:

http://php.net/manual/en/function.preg-match.php

You can convert a string in the $_POST or $_GET array to an int or float 
value using appropriate functions:

http://php.net/manual/en/function.intval.php
http://php.net/manual/en/function.floatval.php

So, for example, as an academic exercise, to read an integer limited to a 
range of 25 .. 75 and with a default value 50 from a get request and send 
it back as a javascript value, you could code something like this in the 
php:

$myval1 = 50; // default value
if ( isset( $_GET['myval1'] ) && preg_match( '/^[2-7][0-9]$/', $_GET
['myval1'] ) == 1 ) {
$myval1 = intval( $_GET['myval1'] );
if ( $myval1 < 25 ) $myval1 = 25; // lower limit value
if ( $myval1 > 75 ) $myval1 = 75; // upper limit value
}

echo "<script type='text/javascript'>\nvar myval1 = {$myval1};\n</script>
\n";

Obviously you also need to make sure that the echo appears at an 
appropriate point in generating the output, I normally try and put such 
things in the document head before I declare any javascript functions.

Personally I try to keep the PHP part as small as possible, so inside 
the top section of my JS where I'm initialising some variables, it's 
likely to be something like:


var myjsVar = <?php echo $myphpvar; ?> ;


As the man says: simples!

Typical ballsed up wrapping ...

$myval1 = 50; // default value

// check if a get value was received and that it has the expected
// text format

if ( isset( $_GET['myval1'] ) && preg_match( '/^[2-7][0-9]$/', $_GET
['myval1'] ) == 1 ) {

	$myval1 = intval( $_GET[ 'myval1' ] ); // get the int value

	if ( $myval1 < 25 ) $myval1 = 25; // lower limit value

	if ( $myval1 > 75 ) $myval1 = 75; // upper limit value 

}

Whether or not it IS running on the client is immaterial. The value is 
still passed via HTML.

FYI, I found the answer at codingforums.
I got it without any BS.

When you asked at that forum, did you include a condescending paragraph 
such as you did here? And usually do when you ask questions?

Beauregard, you don't understand.  Richard NEVER does anything wrong -

So, what is the answer you found? I have a similar need, and although I 
think other replies covered it well enough, I'd appreciate your sharing the 
information, especially if it is any easier.

Thanks,
