pass vars in php & javascript

[Anon]

i have written a simple php poll script adn want to enhance it so that when you vote rather than reloading the page to show resluts it automatically loads a pop up window. how can i pass varibles between php and javascript ??

poll.php - choose vote from input radio button form details

<form>
<input type="radio" name="vote" value="choice2">
<input type="radio" name="vote" value="choice2"> // the choice is dynamically produced from php $key
</form>

script at top of page -

<script language="javascript">
function newwin() {

window.open('pollres.php?vote='choice from vote','newWindow','toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbars=no,resizeable=0,width=200,height=350');

}
</script>

i cannot get the popup window to take the varibles so that it opens : -

pollres.php?vote='choice'

any ideas ??

Use urlencode() to encode your parameters. It should solve your problem.

sorry, not sure how to use urlencode, any tips ??

ive looked at the php manual and it doesn't make that much sense to me

thanx

Sorry, I had read your post too quickly. You want to pass PHP the value of the radio button the user selected ? Try this (tested on IE) :

function getchoice()
{
var v=document.forms[0].vote;
for(i=0;i<v.length;i++)
if(v.checked)
return v.value;
return "";
}

window.open('pollres.php?vote='+getchoice(),'newWindow',...);

Hi,

I have a question. I am working on a php4/mysql furniture catalogue site which has italian and french products,

and therefore I have special characters such "é", "è", "ù", and so on... in the products names.

I use a the javascript function "variable_in_link(variable-value)" and window.open to open a photo viewer for each product.
It works well, but with a product name like "Noé", the variable passed loses the accent (é).

I tried php's urlencode, but it looks like javascript "parses"(sorry:-) ) the link, not php (?)
so my name variable "Noé" arrives in the pop-up as "N" (kind of strange, I also lose the "o" :-)

Any ideas ? Thanks in advance !
Here's the code (hope it appears).

$clid > collection id (the collection the product belongs to)
$clnm > collection's name ("Noé" arrives as "N" in the pop-up window)
$bdnm > brand name (the brand the collection belongs to)

The Javascript :

</title>

<script LANGUAGE="JavaScript">

<!--

function variable_in_link(varible_value)

// function variable_in_link will assign the first variable

// passed to it as variable_value

{

new_win = window.open('http://127.0.0.1/~christia/decologia/viewer.php?'+varible_value+'','', 'location=yes,status=yes,menubar=yes,scrollbars=yes,resizable=yes,width=640,height=400,left=10,top=10')

}

//-->

</script>

...and the PHP

while ( $photoqueryrow = mysql_fetch_array($hpphotoquery))

		 {

		 $hpphoto = $photoqueryrow["PhotoURL"];



		?>



		 <a HREF="javascript:variable_in_link('

<?php

echo ("clid=" . $clid . "&clnm=");

echo (urlencode($clnm));

echo ("&bdnm=");

echo (urlencode($bdnm));

?>

')">

		 <?php

echo ("

		 <img SRC='" . $hpphoto . "' "

		 );

		 }



	?>
