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.
