[PHP] control browser with a href tag
hi friends, i have two pages: list.php and update.php list.php will have a hyper link that when click on, it will open a new window for user to update info. once user clicks update button on update.php page, i want to close update.php and return to list.php. however if user doesn't click update button, i don't want user to go back to list.php. in other word, freeze up list.php until user closes or clicks update button on update.php. is this possible to do with php? thanks

Yes and no, don't think you intend to, but you may be mixing technologies. You refer to hyperlinks, etc, which is web technologies and windows, which is not unless you use javascript or ajax. With PHP you can cause your browser to open a new browser by adding target=_blank to the hyperlink, but you cannot easily disable functionality of the old browser (It's still open, just usually covered up by the new browser), and if the user clicks your hyperlink again a 3rd browser will be opened. You could name your target (target=mypage) which means if the user clicks it a new browser will be opened, and if the user clicks the same link again, a 3rd window will not be opened, but the page in the mypage target will be refreshed. HTH, Warren Vail after read all your replies, i understand and want to redefine the problem. if user clicks on the hyperlink on list.php page, i want to open a new windows for user to update info. once user clicks update on update.php page, i want to close the update.php page automatically and refresh list.php page. i think this is possible. can someone give me suggestions how to do this? thanks -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I have actually done what you are looking for... Here is how I do it:
On the search page, write the search phrase into a session variable so you
can access it from another page and then run this code:
?PHP
$sortOrder = $_SESSION['order'];
$search = $_SESSION['search'];
$select = SELECT * FROM .$table. WHERE blah blah blah blah blah;
$export = mysql_query($select);
$fields = mysql_num_fields($export);
for ($i = 0; $i $fields; $i++) {
$header .= mysql_field_name($export, $i) . \t;
}
while($row = mysql_fetch_row($export)) {
$line = '';
foreach($row as $value) {
if ((!isset($value)) or ($value == )) {
$value = \t;
}
else
{
$value = str_replace('', '', $value);
$value = '' . $value . '' . \t;
} $line .= $value;
}
$data .= trim($line). \n;
}
$data = str_replace(\r, , $data);
if ($data ==) {
$data =\n(0) Records Found!\n;
}
header(Content-type: application/x-msdownload);
header(Content-Disposition: attachment; filename=Export.xls);
header(Pragma: no-cache);
header(Expires: 0);
print $header\n$data;
?
What that does is it writes the current search pattern into an excel file
called Export.xls and downloads it to your harddrive. I am in the process of
re-writing it to work as a function, but have had mixed results so far. I'm
learning functions right now :)
If you know functions, and want to take a stab at re-writing it, I can
provide you with the code I have so far :)
thank you for the suggestion, but here is another problem that i try to
avoid saving mysql statement to query from the table again.
let say that user searched and found 10 records,
in the meantime, other users may change any of these 10 records,
so if we saved mysql statement and re-run mysql statement again, the
result might be different. to prevent this problem, i only want to
download records that returned on this page only.
thanks,

[PHP] generate xls file on fly
hi friends,
i have a php page with the following logic:
html
head
titleDownload/title
/head
table
trtdTitle/tdtdAuthor/td/tr
? $sql = select title,author from book where title != null and author !=
null; ?
? $rs = mysql_query($sql) or die(mysql_error()); ?
? while($row = mysql_fetch_array($rs)) { ?
trtd?=$row[0];?/tdtd?=$row[1];?/td/tr
? } ?
trtda href=Download Into Excel File/a/td/tr
/table
/html
is there anyway to generate this into xls file w/o using fopen fwrite to
the server? my goal is to have a link after the table and user can click
on that link and a save window pop up to allow user to save to local disk.
appreciate very much for any input.

why not store the whole SQL statement in a session variable, so it can
work with any table??? i never use session before, but i'll look into it
to see if it works for me.
any suggestion for a tutorial on session in php??? thanks.

Tim
setcookie from php.net states the following:
setcookie() defines a cookie to be sent along with the rest of the HTTP
headers. Like other headers, cookies must be sent before any output from
your script (this is a protocol restriction). This requires that you place
calls to this function prior to any output, including html and head
tags as well as any whitespace
call setcookie before you output ANY THING, even error
hope that helps.
