[PHP] Die Page, Die! (Was: Preview button to show PDF without submitting post data?)
PHP List,
Okay, so I've got a nice situation where a form has a preview button as
well as a submit button. When the user presses Submit, the page
reloads, and it emails a PDF.
If the user presses Preview, it launches a new page in a new window,
and also outputs a PDF directly to the user so they can review it.
All good, but I don't need that second window open once the PDF has been
shown to the user.
For some reason I can't kill that second window. I've tried two methods.
Killing it with PHP, and killing it with JavaScript.
Here's the PHP version:
if (isset($_POST['preview']))
{
$pdf-Output(preview.pdf, D);
die(PDF プレビュー出しました / PDF Preview Displayed);
}
Here's the JavaScript version:
if (isset($_POST['preview']))
{
$pdf-Output(preview.pdf, D);
echo 'script type=text/javascriptjavascript:self.close();/script';
}
But in either case, I keep getting that second page coming out, with the
whole form rendered all over again.
How can I kill a page? Once the PDF is rendered, I don't need it. I'd be
okay if it came down to the browser then closed, but it would be better
if the server sent the PDF and didn't send the page.
Any advice would be much appreciated.

[PHP] die function
Hi all,
I have a machine that must insert in cron in a mysql db in another
remote machine.
The problem is that I cannot know if the connection in the first
machine (adsl) go down because no entry in the machine log is
generated. I would like to redirect the die function in a e-mail that
say me what happens.
I found a script
?php
function die_script($errmsg)
{
print $errmsg . /body/html;
die;
}
?
and I tried to insert a mail() before die function but I cannot call
the function in this way:
or die(Connection failed: . die_script());
But no email is generated.
How can I do?
Thanks
Barbara

[PHP] php die function for MySQL connection errors
Hi,
I have a quick question about using the PHP die() function. I'm building a
site around a MySQL database, and when I connect to the database from a PHP
page I use the following code:
$connection = mysql_connect($host, $user, $password)
or die(Error connecting to SQL server);
$db = mysql_select_db($database, $connection)
or die('Error connecting to database);
Simple enough so far right? So if there is a problem connecting in anyway,
an error message appears. What I want though is to redirect to a properly
separate error page, rather than just have a basic text mesage.
I changed the code to this:
$connection = mysql_connect($host, $user, $password)
or die(Error connecting to SQL server);
$db = mysql_select_db($database, $connection)
or header('Location: ../errors/databaseselect.php');
Which works fine (tested by deliberately misnaming database so it can't find
it).
However if I then use the same approach for the server connection error,
like below, it doesn't work.
$connection = mysql_connect($host, $user, $password)
or header('Location: ../errors/servererror.php');
$db = mysql_select_db($database, $connection)
or header('Location: ../errors/databaseselect.php');
I get a variety of error messages dependant on what I tweek to try and make
it work. I've tried all I can think of, and I've tried putting the header
function inside a die function to no avail. I don't understand why it works
for the database connect error but not the server error.
If anyone has any suggestions as to what the problem is or how I could
improve my technique I'd love to know. I'm sure I can't be the only person
who has wanted to do something like this, but I can't find any references
online to anything other than simple text error messages. I'm relatively new
to PHP but not programming in general so please don't be afraid to fire big
words at me.
Thanks in advance!

you haven't told us what error messages you are getting - however my
guess is that your header() call fails because of the error message
produced by mysql_connect() if so you can try @mysql_connect($host,
$user, $password) instead so that error messages to browser are
suppressed ( you can achieve the same by editing your php.in)

I have a quick question about using the PHP die() function.
[...]
I changed the code to this:
$connection = mysql_connect($host, $user, $password)
or die(Error connecting to SQL server);
$db = mysql_select_db($database, $connection)
or header('Location: ../errors/databaseselect.php');
Which works fine (tested by deliberately misnaming database so it can't
find it).
However if I then use the same approach for the server connection error,
like below, it doesn't work.
$connection = mysql_connect($host, $user, $password)
or header('Location: ../errors/servererror.php');
On failure, this causes the header to be sent, but doesn't actually stop execution of
your script, so...
$db = mysql_select_db($database, $connection)
this will now fail because you don't have a valid $connection.
or header('Location: ../errors/databaseselect.php');
The bottom line is, whenever you issue a header(Location: ) call, you also need
to cause the script to die if your logic demands that -- so the above should be
written something like:
if (!$connection = mysql_connect($host, $user, $password)):
header('Location: ../errors/servererror.php');
die();
endif;
if (!$db = mysql_select_db($database, $connection)):
header('Location: ../errors/databaseselect.php');
die();
endif;
(And, BTW, the HTTP definition says that the Location: header should specify a full
absolute URL, so that should be:
header(Location: http://your.server.name/path/to/errors/servererror.php;);
etc.)
Cheers!
Mike

[PHP] die! die! directory!
Help! I've been beating on a problem all day and think I've isolated the problem to the following line: print input type=image src=./maps/map1.jpg name=coordinate ; If I call the statement as is, I get a little red x where my map should be. In earlier calls to the same directory, I can get a server error, misconfiguration... if I change the line to: print input type=image src=map1.jpg name=coordinate ; I see the image. is there a way to declare the path before asking for the file, or a better way to state the file location. Any help will be greatly appreciated. Hugh
