I have a TON of forms that I have to populate, can I make a PDF file using
Acrobat Professional, and then use PHP to populate those forms and have text
inserted into the pre-made text fields that I made using Acrobat? And if
so, what is the best tool for that? I'd prefer to do it for free, but
spending $$ is fine too.
Thanks
Dan

How else would php know you want session started? You can turn
session.auto_start on, but then you don't have control over session
parameters.

You can use preg_replace_callback or the e pattern modifier to let you
run php code for the replacement:

Hi Comex,
Thanks for your reply, I have modified the code so I have a call back
function:
echo = preg_replace_callback( '/<p[^>]*>(.*?)<\/p>/ms', "callback",
file_get_contents($_GET['file']) );
function callback($matches){
return
'<form name="form" target="_parent"
action="/index.php?action=edit_paragraph&file='.$_GET['file'].'"
method="post">
<input type="hidden" name="old_html"
value="'.htmlentities($matches[0]).'">
<p><a href="javascript:;"
onclick="document.form.submit();">'.$matches[1].'</a></p>
</form>';
}
But I still can't see how I can increment a value in each return string?

function callback($matches) {
static $i = 0; // <-- maintains counter within function scope
$i++;
return "<form name="form$i">....</form>";
}
btw, i've been meaning to mention this in the last few posts of
yours, but have you considered using DOM to make this happen. When
ever I see a regex solution for parsing an html document, it makes
me cringe.

Hi Curt,
Thanks for your reply. So basically I do something like:
$doc = new DOMDocument();
$doc->loadHTML($file);
$p = $doc->getElementsByTagName('p');
How would then wrap the following around each <p> tag:
<form name="form" target="_parent"
action="/index.php?action=edit_paragraph&file='.$_GET['file'].'"
method="post">
<input type="hidden" name="old_html"
value="'.htmlentities($matches[0]).'">
<p><a href="javascript:;"
onclick="document.form.submit();">'.$matches[1].'</a></p>
</form>
BTW if its not obvious I am trying to create a CMS that lets users edit
anything within a <p> tag!

Hello
Is it good to use exception handling for error handling or I should use only
for exceptions?
For example:
Is it good to throwing user input errors with throw new Exception().
Thanks
--- End Message ---

I would recommend keeping error handling and exceptions separate.

I'm not sure if I understand how you mean by this but it sounds to
me that your asking if you should use exception catching vs if
statments:
try {
is_valid_username($username);
catch (Exception $e) {
$errors[] = $e->errorMessage;
}
imo, programming like that doesn't make sense, exceptions are more
designed for errors in assumed succesfull code. Consider:
<?php
try {
$dbh = new PDO('mysql:host=localhost;dbname=test', '', '');
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sql = "select bar from foo";
$stmt = $dbh->prepare($sql);
$stmt->execute();
}
catch (PDOException $e) {
echo $e, "\n";
exit();
}
// some code to use the valid $stmt object
?>
There are two places where that code will issue an exception:
1. if a connection to the db fails, which it shouldn't
2. if the column bar doesn't exit of table foo doesn't exist
which should exist (unless the DBA decides to rename the table
or column.
After the catch statement, I know that $stmt is going to be valid
and can check for valid results or not.
The use of the try catch is to ensure that something that is
suppose to happen 100% of the time succesfully, if it doesn't we
have an exceptional case and should bail out in a friendly
manner.
Curt.

Hello,
I would also go by keeping them separate; it helps both in logic-flow, and
maintenence. Not to mention, exception handlers are design to do just that
- handle exceptions.

Hello, Sir:
I just installed PHP with pdflib :
--------------------------------------------------------------------
PHP-4.4.1
pdflib PDFlib GmbH Version 6.0.2
pdflib PECL Version 2.0.3
apache 1.3.34
in Liunx FC1.

When I run the script , I got the error messages as following:

Some thing wrong with this function at the 8th parameter, I think:
>>>>>>pdf_show_boxed($pdf,$text,50,650,150,100,'right','');
if I remove the 8th parameter, It would tell me :
---------------------------------------------------------------------------------------------------------
Warning: pdf_show_boxed() expects exactly 8 parameters, 7 given in

What should I do?

If you note at php.net/mail that the SMTP setting is only for
windows. Under *nix only as current installed MTA like sendmail can
be used.
you can set your sendmail_path to pass parameters like :
/sbin/sendmail -f [EMAIL PROTECTED]

iirc, Firefox 1.5 has improved its caching system, in paticular to the
back button drama.

According to the code you cat'ed there is no panda object that is
defined so my first assumption is that you have a file that is set
in your php.ini:
auto_prepend_file=/some/panda.php
> Segmentation fault (core dumped)
Even at that, this core dump shouldn't be happening. I'm assuming
you installed this via ports. There are two thing i can think of
that should be checked before getting a backtrace:
1) are you uptodate on your ports? have you done a cvsup
recently?
2) what does 'php -v' say?

hi Curt.
for the first question :
yes i always do the things below:
#portupgrade -arR
and
#cvsup -g -L 2 /etc/por...
i mean yes my ports up to date.
and for the second :
[EMAIL PROTECTED] php -v
Segmentation fault (core dumped)
[EMAIL PROTECTED] php-config --version
5.0.5
[EMAIL PROTECTED]
dont know how to solve this troublesome problem.
