RE: Re[2]: [PHP] Self Submitting Form
Ah ha!
I think I found where the problem lies(and also our confusing
disconnect). Even though you and I were doing pretty much the same
thing, your case worked fine in the instance where the parameter being
submitted in the self submitting form was only one word. If you changed
your test case to something like hi there (which is what I was using
in my testing), it breaks. Why? The parameter needs to be urlencoded
first.
Thank you very much for your help and suggestions, Toby! I really
appreciate your time and effort in helping me to see the light.

[PHP] Self Submitting Form
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=#FF
TEXT=#00 LINK=#00 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=myvarVALUE='+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!

Re: [PHP] Self Submitting Form
Hi Sam,
I am not sure I know what you want to do...
I tried to recreate your problem:
test.html
form name=myform1 method=get action=
input type=hidden name=myvar1 value=testing
script
window.open(test2.html, test);
/script
/form
test2.html
BODY onLoad=document.forms[0].submit();
form name=myform1 method=get action=test3.html
INPUT TYPE=hidden NAME=do_preview VALUE=1
script
document.write('INPUT TYPE=hidden NAME=itworks
VALUE='+opener.myform1.myvar1.value+'');
/script
/FORM
/BODY
test3.html
script language=Javascript
function parseQueryString (str)
{
str = str ? str : location.search;
var query = str.charAt(0) == '?' ? str.substring(1) : str;
var args = new Object();
if (query)
{
var fields = query.split('');
for (var f = 0; f fields.length; f++)
{
var field = fields[f].split('=');
args[unescape(field[0].replace(/\+/g, ' '))] =
unescape(field[1].replace(/\+/g, ' '));
}
}
return args;
}
var args = parseQueryString ();
for (var arg in args)
{
document.write(arg + ': ' + args[arg] + 'BR');
}
/script
And the output is:
do_preview: 1
itworks: testing
As should be expected...
Pls try to specify your problem.

RE: [PHP] Self Submitting Form
Hi Toby!
Thank you for your suggestion, but unfortunately you are using GET in your test2.html
file. I specifically stated in my initial email that due to the fact that I am using
textareas in my original form (your test1.html) that I did not want to use GET for it
might run the risk of overstepping the bounds of how many characters the browser will
accept in the GET string.
Any other suggestions that anyone else has would be most appreciated as I am still
pretty stuck on this.
As always, thanks in advance!
