have a look at peg_replace in the man, you could also get your users to save as 
filtered html which get rid of some of it, there's also a MS tool "Microsoft Office 
HTML Filter 2" that will clean it some more, it says it's for word 2000 but it works 
fine for word 2002/XP.

but your best option is to use preg_replace to swap out all the "smart tags" etc.

As far as anyone is concerned they do the same... Check the archives for

fopen? here is a quick snip from the user comments $page= join ('', file
('www.yahoo.com')); that basically loads all the HTML at Yahoo.com into
the varible $page... neat huh :)

PHP doesn't really write HTML for you, thats your job... so a function or
a simple loop could do this...
for ($i=0; $i<3; $i++)
    echo "<input type='hidden' name='$$var[$i]' value='$var[$i]'>";

No problems :)

I think mailing list managers like Yahoo, ezmlm, etc all have "features" in
them to suspect bots and programs from subscribing/posting to the groups.  I
know I've had trouble subscribing/posting to groups managed by ezmlm...

Probably there is a header or two that PHP automatically sets which makes
the mailing lists suspicious... or something!! I don't know enough about
email to really come up with an answer!!!

You could try setting some headers similar to what your email client sets,
to see if it's something "missing"... or try sending yourself an email from
a php script and analysing the headers it sets.

It could also be the lack of a return address or something similar that
throws the lists off too.

Most mailing lists reject mail if the Subject is blank.

That would probably explain why your subjectless 2nd example is disappearing
into the void.

Richard,
Thanks for the reply.
'top' shows that the script is being run as nobody.
the '2<' stuff allow the password to be passed as a file descriptor and I 
think it is this that is breaking.
I have setup a nobody directory just for this. I then set the HOME variable 
to point to this directory.
If on command line, I su to nobody, setup the enviroment variable HOME, 
GNUPGHOME etc then run the php script command line it runs perfectly.
The problem seems to be that when running from apache, it can't handle the 2< 
bit.
If I set up a test key with no password, then I can run the script perfectly 
(ie I don't need to pass the password-fd bit.)
If I use exec, I get the same results.
I'll add the implode bits and try that.

Regards,
Jon

I'm trying to go about doing this:

While there is data in an array, get and echo individual pieces from
this array and execute a mysql query that gets the other info in the
table where arraypiece. Stop when all arraypice have been echoed.

The array gets its values from and checkbox form. I got that part: 

<input type="checkbox" name="check[]" value="'.$ID.'">

So I count the number of times there is something in $check, which I
think is done like so:

for($i = 0; $i < sizeof($check); $i++) {
echo $i;
}

that should give me the number of checboxes clicked. (it does, I
verified)

so, now I say:

for($i = 0; $i < sizeof($check); $i++) {
# echo $i;
echo '<p>';
$data = $check[$i]; 
echo $data;

which brings me to getting the rest of the data from the tables (the
array I was talking about holds the ID) (aka the key) but I still need
to put the key in the door.

Ok, so no I would need to loop a mysql query for as long as there is
data in the array, - since I only have one key for each row.

Let me try to write it:

for($i = 0; $i < sizeof($check); $i++) {
# echo $i;
echo '<p>';
$data = $check[$i]; 
#echo $data;
mysql_query("SELECT * FROM table WHERE ID = '$data'");
$db_ID = $row["ID"];
$db_picture_name = $row["picture_name"];
echo $db_ID;
echo $db_picture_name;
}

Now, this should do the trick, let's test it ... testing ... 

Nope, mysql can't execute that query...
Hmmm...


I get this

could not execute queryYou have an error in your SQL syntax near 'table
WHERE ID = '1'' at line 1

no shit! I actually don't have a table called table!

Fixed that, testing ....

could not execute queryNo Database Selected

ok, let's do that. (I've been up all nigh what do you want!)

ok, now what?!

I get NOTHING! NOTHING! WHAAAAHHT!

I tried hardcoding the $ID, nothing, so that must be ok, as we have
proved earlier,

By this time I ended up with this code:

for($i = 0; $i < sizeof($check); $i++) {
# echo $i;
echo '<p>';
$data = $check[$i]; 
#echo $data;
mysql_query("SELECT * FROM kodak_user_pictures WHERE ID = '1'")
or die ('could not execute query '.mysql_error());
$db_ID = $row["ID"];
$db_picture_name = $row["picture_name"];
echo $db_ID;
echo $db_picture_name;
}

of course it gives me nothing! 

What the hell is $row?

Ok, let's fix that.

for($i = 0; $i < sizeof($check); $i++) {
# echo $i;
echo '<p>';
$data = $check[$i]; 
#echo $data;
$db_data = mysql_query("SELECT * FROM kodak_user_pictures WHERE ID =
'1'");
$row = mysql_fetch_array(db_data);
$db_ID = $row["ID"];
$db_picture_name = $row["picture_name"];
echo $db_ID;
echo $db_picture_name;
}

now I get this... I'm also getting tired...

Warning: mysql_fetch_array(): supplied argument is not a valid MySQL
result resource

STUPID $ SIGN! (look near db_data, nope, the second one!)

Ok, let's test ... 

Ok, good, let's switch the hardcoded 1 from the query back to the
$data...
 Testing ...

Ok, now it only gets one...

Let's try a for each

for($i = 0; $i < sizeof($check); $i++) {
# echo $i;
echo '<p>';
$data = $check[$i]; 
#echo $data;
foreach ($data as $check[$i]) {
$db_data = mysql_query("SELECT * FROM kodak_user_pictures WHERE ID =
'$data'");
$row = mysql_fetch_array($db_data);
$db_ID = $row["ID"];
$db_picture_name = $row["picture_name"];
echo $db_ID;
echo $db_picture_name;
}
}

Warning: Invalid argument supplied for foreach()

Ok... 

Not better, but let's see...

Ok, now I ende up with this code:

for($i = 0; $i < sizeof($check); $i++) {
# echo $i;
echo '<p>';
$data = $check[$i];
$db_data = ("SELECT * FROM mytable WHERE ID = '$check[$i]'");
$row = mysql_query($db_data);
# $row = mysql_fetch_array($db_data);
$db_ID = $row["ID"];
$db_picture_name = $row["picture_name"];
echo $db_ID;
echo $db_picture_name;
#echo $data;
}

I don';t know what to do, I get nothing, I think the error is that I do
not know how to call the mysql query results into the variables fro
echoing, please I beg you someone tell me.

Now, this should do the trick, let's test it ... testing ... 

Nope, mysql can't execute that query...
Hmmm...


I get this

could not execute queryYou have an error in your SQL syntax near 'table
WHERE ID = '1'' at line 1

no shit! I actually don't have a table called table!

Fixed that, testing ....

could not execute queryNo Database Selected

ok, let's do that. (I've been up all nigh what do you want!)

ok, now what?!

I get NOTHING! NOTHING! WHAAAAHHT!

I tried hardcoding the $ID, nothing, so that must be ok, as we have
proved earlier,

By this time I ended up with this code:

for($i = 0; $i < sizeof($check); $i++) {
# echo $i;
echo '<p>';
$data = $check[$i]; 
#echo $data;
mysql_query("SELECT * FROM kodak_user_pictures WHERE ID = '1'")
or die ('could not execute query '.mysql_error());
$db_ID = $row["ID"];
$db_picture_name = $row["picture_name"];
echo $db_ID;
echo $db_picture_name;
}

of course it gives me nothing! 

What the hell is $row?

Ok, let's fix that.

for($i = 0; $i < sizeof($check); $i++) {
# echo $i;
echo '<p>';
$data = $check[$i]; 
#echo $data;
$db_data = mysql_query("SELECT * FROM kodak_user_pictures WHERE ID =
'1'");
$row = mysql_fetch_array(db_data);
$db_ID = $row["ID"];
$db_picture_name = $row["picture_name"];
echo $db_ID;
echo $db_picture_name;
}

now I get this... I'm also getting tired...

Warning: mysql_fetch_array(): supplied argument is not a valid MySQL
result resource

STUPID $ SIGN! (look near db_data, nope, the second one!)

Ok, let's test ... 

Ok, good, let's switch the hardcoded 1 from the query back to the
$data...
 Testing ...

Ok, now it only gets one...

Let's try a for each

for($i = 0; $i < sizeof($check); $i++) {
# echo $i;
echo '<p>';
$data = $check[$i]; 
#echo $data;
foreach ($data as $check[$i]) {
$db_data = mysql_query("SELECT * FROM kodak_user_pictures WHERE ID =
'$data'");
$row = mysql_fetch_array($db_data);
$db_ID = $row["ID"];
$db_picture_name = $row["picture_name"];
echo $db_ID;
echo $db_picture_name;
}
}

Warning: Invalid argument supplied for foreach()

Ok... 

Not better, but let's see...

Ok, now I ende up with this code:

for($i = 0; $i < sizeof($check); $i++) {
# echo $i;
echo '<p>';
$data = $check[$i];
$db_data = ("SELECT * FROM mytable WHERE ID = '$check[$i]'");
$row = mysql_query($db_data);
# $row = mysql_fetch_array($db_data);
$db_ID = $row["ID"];
$db_picture_name = $row["picture_name"];
echo $db_ID;
echo $db_picture_name;
#echo $data;
}

I don';t know what to do, I get nothing, I think the error is that I do
not know how to call the mysql query results into the variables fro
echoing, please I beg you someone tell me.

Hi everybody,

i wrote a script which will be executed by HREF's. If a command is going to be 
executed by a click on a link the page reloads itself and jumps
in the part of the script, which should be executed.

Normaly I wrote some like this for doing this:

echo '<a href="'.$PHP_SELF.'?action=delete&id='.$arrResult['id'].'" class="text01">';

but now in a very special case i forgot to write $PHP_SELF like this

<a href="?action=delete&id='.$arrResult['id'].'" class="text01">

without knowing that I have forgotten to write this $PHP_SELF thing I clicked on the 
Link and i did execute the Script, like i wanted it to.

Is it normal that it works so fine? Can I use this everytime I link on the same page 
for script execusion?

Can I send Forms via an PHP Function like the submit() statement in Javascript?

Have a nice day, and please answer.

i'm setting up a messages option on my site, i was looking in the
documentation and read that if headers are not included in an e-mail, the
message is sent to the junk folder, i don't use hotmail (so i would not
know), however i am adding headers: using

// The headers
$myHeaders = "From: \"".Autoresponse."\" <".$myAddress.">\r\n";
$myHeaders .= "To: \"".$myName."\" <".$myAddress.">\r\n";
$myHeaders .= "Reply-To: \"".$myName."\" <".$myAddress.">\r\n";
$myHeaders .= "MIME-Version: 1.0\r\n";
$myHeaders .= "Content-Type: text/html; charset=iso-8859-1\r\n";
$myHeaders .= "X-Priority: 1\r\n";
$myHeaders .= "X-MSMail-Priority: High\r\n";
$myHeaders .= "X-Mailer: Just My Server";

// send the e-mail
mail($myAddress, $mySubject, $myMessage, $myHeaders);

##############################
when testing the file i get the response e-mail, however at the top of the
e-mail i get the following:


Content-Type: text/html; charset=iso-8859-1 X-Priority: 1 X-MSMail-Priority:
High X-Mailer: Just My Server

this must mean that i have written the headers wrong, can someone point me
in the right direction

thanks

Is there a way to determine what a user clicked from a page and pull info from 
that page to the new page from an array?

Example on one page:
echo "<a href='test.php?picName=$lines[$i]'><img 
src='Bid2002/$lines[$i]'></a>&nbsp;";
?>

on the test.php page how do i determine which picture the user clicked on?

ORDER is a reserved word in MySQL.

Change the query and escape order aswell

'order'='1' WHERE ID='2'

Or, rename the order column to something else.

Ahem. Why not check out the MySQL docs for reserved words (they _are_ right
there ...):

http://www.mysql.com/doc/en/Reserved_words.html

PHP Docs are for PHP. MySQL Docs are for MySQL. PHP != MySQL.

Not real sure if you *want* the PHP file interpreted or not, but if not,
try
this:

<?php
  $html = file("http://example.com/whatever.htm";) or die("Could not load
remote HTML");
  echo implode('', $html);
?>

But if I should also check 'object-oriented' then I believe it deals

Sorry 'bout that. Actually, if you have an idea of what OO 
("object-oriented") is, I think I can say that "procedural" is just the 
opposite of it.

I tried Google myself and this came out on top:

  "Writing Procedural Code in Non-Procedural SQL"

There's a short explanation but I think it's enough to give you some hint 
about "procedural code".

I'd like to be able to modify the switch variable inside a case
statement, like this:

switch ($foo) {
  case 'step2':
    do_step2();
    if ($error) $foo='step1'; //repeat step1
  break;

  case 'step1':
    do_step1();
  break;

  case 'a_third_thing':
    do_something_else();
  break;
}

Can you modify the variable ($foo) inside a case statement and
have it evaluated for subsequent 'case's like this? If not, I 
will have to revert to a series of if statements, in which this can
be done:

if ($foo=='step2') {
  do_step2();
  if ($error) $foo='step1';
}
if ($foo=='step1') {
  do_step1();
}
etc.

Switch-case seems cleaner, and I'd prefer to stick with it.

If you don't break, it continues to execute all the code until
the end of the switch, ignoring any subsequent case
statements.

In my example, eliminating the break after step2 would
cause execution of do_step1(), but also do_something_else(),
which is not desired.

Regardless of how many break statements you take away (even
if only 1), case statements appear to be ignored after the
first match is made. I need a way to make the switch statement
continue evaluating case-matches, even after the first case
match is made. Further, it should allow one case segment to
alter the switch variable and have such alteration taken 
into account for subsequent matches.

Here's a more illustrative example of my situation:

switch ($foo) {
  case 'a':
    if (do_a()) echo "a was done";
    else $foo='menu';
  break;

  case 'b':
    if (do_b()) echo "b was done";
    else $foo='menu';
  break;

  case 'menu':
    print_menu();
  break;

  case 'logout':
    do_logout();
  break;
}

that code will not print_menu if do_a fails, since
it exits the switch statement upon seeing a break.

if I remove the break after do_a, it will execute
do_a and do_b -- bad. what we really want is for it
to execute do_a and if do_a returns false, print_menu.

It seems like you can do something like this:

switch ($foo) {
   case 'a':
     if (do_a()) echo "a was done";
     else print_menu(); // changes here
   break;

   case 'b':
     if (do_b()) echo "b was done";
     else print_menu(); // changes here
   break;

   case 'menu':
     print_menu();
   break;

   case 'logout':
     do_logout();
   break;
}

Or, if for some reason you can't do that (or you don't want to)...

Here's another way: (I'm not sure if this will work.)

switch ($foo) {
   case 'a':
     if (do_a()) echo "a was done";
     else $foo='menu';
   
   case 'menu':
     print_menu();
   break;

   case 'b':
     if (do_b()) echo "b was done";
     else $foo='menu';

   case 'menu':
     print_menu();
   break;

   case 'logout':
     do_logout();
   break;
}

It doesn't look "clean" but it might just work...

BTW, I know this is just an example, but I expect you're doing your 

  if(){
  } else {
  }

properly in your real code...

This is my form:

  Group:<BR><INPUT TYPE=TEXT NAME="group" SIZE=8>&nbsp;&nbsp;
  <INPUT TYPE=BUTTON VALUE=" OK!" onClick="Javascript:validate(this);">

and the function validate:
function validate() {
  var ok=true;
 if (document.answerform.name.value=='') {
  ok=false;
  alert('Please write Your name')
  document.answerform.name.focus();
  document.answerform.name.select();

  alert('What group?')

 }
 if (ok==true) {
  location.href='groups/collect_answer.php?name=<?php echo $name;

  return true;
 } else { return false; }
}

and this doesn't work and I can't see why not

Looks like a javascript question to me.

Ahem. Why not check out the MySQL docs for reserved words (they _are_

PHP Docs are for PHP. MySQL Docs are for MySQL. PHP != MySQL.

Yep, figured it just now, thanks anyway, ahhh.. You'd thing they put
reserved names right besides the damn mysql command in the manual. Alas
it shall not be so.

Then check the MySQL manual using the URL I posted!

PHP doesn't care about the hundred or so reserved MySQL words. MySQL does.
Perhaps you're confusing the two. Please check what I said:

PHP != MySQL

The documentation for each is separate. PHP has "convenience" functions for
talking to a MySQL database. It does not parse or check your SQL statements
for correctness - it just passes them along and lets the MySQL library do
its work. PHP does this for a great number of products: cURL, GD functions,
various ODBC interfaces, etc. It's up to you to read the support docs for
those products to use them fully. The docs for PHP don't need to be
cluttered with deep and detailed explanations of every supported interface,
not would I expect them to.
