PLEASE: javascript to php help

Anon

Please help. I needed an answer to my question regarding getting textarea to php VIA javascript.

SORRY to say this, but people answered that PHP gets the variable already. However, I already KNOW this. I MUST use Javascript. If you would like to know why, I will tell you. I am NOT submitting a form. I don't want to submit a form. I am using an onclick Javascript window opener (clicking on some text opens up a text window, duplicating what the user just filled in), and this is done via the Javascript variable: "document.form1.textarea.value"

My question is how do I get THAT into PHP??? PHP will ONLY capture the original textarea variable if the form is submitted via get or post. I am not submitting at all. I don't want to, for my own personal reasons.

I will post my original question here:

When I type into textarea, and click the "submit button," the "javascript variable"
that holds what the visitor typed is this:
document.form1.textarea.value

My question is: On that next page that appears, how can I store that Javascript
variable in a PHP variable?

I mean, do I put the php stuff into my javascript tags? Nothing I try seems to
work. Here is an example of what I tried:

<SCRIPT LANGUAGE="JavaScript">
<?php
$my_variable = "document.form1.textarea.value";
?>
</SCRIPT

but, of course, that doesn't work.

You may ask why I want to do this? Well, the reason is that after Javascript is
used (I MUST use Javascript for programming reasons), I want PHP to store that
variable into a mySQL database.

Okay, you are still a little obfuscating... but here is my understanding:

1) you have a static page with a text area
2) you click on a link or something else which changes the URL to the PHP file
3) in that PHP file you want the contents of the textarea from the previous page
4) you want to do this WITHOUT submitting any form, etc.

If the above is what you want, do this:

When you call the new URL from javascript, call it like this:

I'm assuming you are going to do a document.location.href to change the location of the current document to the PHP file (let's call it step2.php). You use the same URL if you want to open a window:

function changeURL() {
// get the contens into a local variable
theText = document.form1.textarea.value;

// create the new URL
newurl = "step2.php?text=" + escape(theText);

// load the URL
document.location.href = newurl;
}

basically, we are passing in a text=value pair to step2.php in the newurl. I used escape to encode the string into a URI format (otherwise if the textarea input contains weird characters, the newurl won't load properly).

you can call the changeURL function from anything like a button, a link, or a onmouseover event, ... whatever you wish to call it from.

i hope this is what you were/are looking for,

In particular, if you want PHP to get the textarea content (or indeed the "next page" at all), the browser has to submit the content to the server in some fashion or the server won't be able to receive it to pass it to PHP.

Actually, you are almost correct. The visitor types in info into the textarea, then clicks my Javascript text link, and then a POPUP window opens which has the textarea in it.

But I think your solution might work.

Thank you

Yes, I did mention that you can put in the URL into the popup window code. I used the document.location object because it is faster to type in than window.open :-)

anyway, good luck and I hope your program works as intended.
