My apologies if this post is somewhat OT. I am having some trouble
figuring something out, and I am hoping you can help.
I have a PHP web form on which a user can enter a number of different
things
into both text and textarea fields. At the bottom of the form is a
preview button which opens another browser window.
I know I can use the GET string to pass these form fields from one
PHP page to another, but with
textareas involved and the possibly large amounts of text being
passed, I didn't want to run the possibility of overrunning the limit
on a GET string. So I figured using a form POST would be more
appropriate.
My thought was to create a self submitting form in the child window, but
I am having
trouble getting it to work (or maybe I should try a different method
entirely to do this...any suggestion welcome!). My code for the
preview window (which contains the self submitting form is as
follows:
<?
if ($do_preview) {
echo $myvar; exit;
}
?>
<HTML>
<HEAD>
<TITLE></TITLE>
<META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=iso-8859-1">
</HEAD>
<BODY onLoad="document.preview_form.submit()" BGCOLOR="#FFFFFF"
TEXT="#000000" LINK="#000000"> <FORM NAME="preview_form" METHOD="post"
ACTION="<? echo $PHP_SELF ?>">
<INPUT TYPE="hidden" NAME="do_preview" VALUE="1">
<script>
document.write('<INPUT TYPE="hidden"
NAME="myvar"VALUE="'+opener.myform1.myvar1.value+'">');
</script>
</FORM>
</BODY>
</HTML>
(I also tried doing an eval within the VALUE attribute, but all that did
was set myvar to the text that I had between the quotes :) )
When I click the preview button on the parent window, I would like to
see the value of the myvar1 variable when the form self
submits...unfortunately, I get nothing. I know it is getting into my
$do_preview block at the top, and I am accessing the variable
correctly because if I do an alert(opener.myform1.myvar1.value), I
get the proper value.
Any thoughts would be greatly appreciated!
