If you want to embed $array[CONSTANT], then the {} is used.
I use {} out of habit for non arrays. Not sure if there is an impact.

The braces are also used when the characters following the variable are
also valid variable name characters :)

Yes, your forms generation class includes a tremendous amount of proven
code, including a bunch of Javascript validation, all of which the
programmer doesn't have to develop himself.
The only real complaint I have about your class is that the class file

If you compare the typing involved in the first case with the typing

That is because you are just thinking about the typing of the generated
HTML. To generate and validate forms, you also have to consider the code
you write to validate and process the forms because the HTML forms do
not process by themselves.
You need to think about the security of your application, so you also
need to validate submitted values, discard invalid values, escape
outputted values, and so on. All that is done with a couple of calls to
the forms class.

That used to be an issue in the 20th century in the PHP 3 days. Since
PHP 4, the PHP code is no longer interpreted. The Zend engine compiles
the PHP code in Zend op codes in the first stage. In the second stage
the op codes are executed. If you use a cache extension like APC, Turck
MMCache, XCache, etc.. the first step is skipped after the first
execution and the size of the original code is not relevant because it
is already compiled in shared memory.
Anyway, the class has all that code because it is necessary to implement
all it supports.

The last two can generate JavaScript, too (still working on that). -- I also am working on more complex validation being automatic: across fields or tables, dependent on other variables, etc. By standardizing the format of metadata and the means of storing system code values, plus core CSS class names, you can use this across projects.

It doesn't help to reset any values. The form data is being resent by the browser itself, just if the user presses the submit button again with the same data.

Re: [PHP] Forms and destroying values
This issue comes over and over again. The trick, as I learned from this list, is to send a redirect to the browser to a confirmation page, so the browser remembers the page redirected to and completely ignores the page that made the redirection so that neither a refresh nor going back to it can repeat the operation. So, if the database update has been succesful, use the header() function to send a 'location' header along with enough arguments in the URL to display a significant confirmation message but make sure that it is different from the URL that makes the database update.

I am also still confused as to why giving them a null value doesn't work. You need to get it clear in your head when PHP is sending data to the client and when it is not. Your assumption is basically that the data in $_POST is actually *connected* to the form displayed in the browser. This is not the case. When you change the contents of $_POST it has no effect on what the browser displays or uses since it's not actually sent to the browser unless you specifically output it in the form of a, erm, form. When the user hits refresh, or uses the back button it is up to the browser what it does. In the case of refresh, if the page being refreshed was created in response to a form being submitted the browser will ask the user if they want to resubmit the data. When using the back button the browser will usually use its cached copy of the page rather than hitting the server again. Hope that makes it clearer. -Stut -Original Message- From: Satyam [mailto:[EMAIL PROTECTED] Sent: January 12, 2007 8:21 AM To: Beauford; PHP Subject: Re: [PHP] Forms and destroying values This issue comes over and over again.

RE: [PHP] Forms and destroying values
Beauford, I think you miss the point. The point is that the values are not remembered by the server at all (after the script finished running), so you don't have to explicitely destroy them. The unset() function is for session variables, which are remembered by the server even after the script finished running, that's their purpose. Your variables are not session variables but normal variables. BUT they are remembered by the browser, which may send them again to your script, that's why you get the same values again. So you have to apply some workaround to make the browser not send them again.

Re: [PHP] Forms and destroying values
As many have already replied to your question, what happens is that upon a refresh the browser is resending the original post variables again. The unset() does work, from the point of the unset() to the end of the script (when all variables except for session variables are unset), PHP will have completely forgotten about those values. But that does not affect the browser at all. On a refresh the browser will send the information again, unless it is tricked via a redirection command to believe the URL used for the post is obsolete. Then, what the browser will do is to remember the URL it was redirected to and drop the 'obsolete' URL so, when the user does a refresh, the browser will be smart enough to go to the 'updated' (the redirected-to) URL instead of the original 'obsolete' one and thus will get the confirmation page again, but without passing through the database transaction.

RE: [PHP] Forms and destroying values
Thanks, a little confusing there. You would think though that once the info is transmitted by the browser it would be forgotten by the browser. Anyway, I do have a work around, and since PHP can't do anything about what the browser does, this will have to suffice. Thanks all. -Original Message- From: Stut [mailto:[EMAIL PROTECTED] Sent: January 12, 2007 11:38 AM To: Beauford Cc: 'PHP' Subject: Re: [PHP] Forms and destroying values Beauford wrote: So the answer is, there is no way to destroy the values.

You need to get it clear in your head when PHP is sending data to the client and when it is not. Your assumption is basically that the data in $_POST is actually *connected* to the form displayed in the browser. This is not the case. When you change the contents of $_POST it has no effect on what the browser displays or uses since it's not actually sent to the browser unless you specifically output it in the form of a, erm, form. When the user hits refresh, or uses the back button it is up to the browser what it does. In the case of refresh, if the page being refreshed was created in response to a form being submitted the browser will ask the user if they want to resubmit the data. When using the back button the browser will usually use its cached copy of the page rather than hitting the server again. Hope that makes it clearer. -Stut -Original Message- From: Satyam [mailto:[EMAIL PROTECTED] Sent: January 12, 2007 8:21 AM To: Beauford; PHP Subject: Re: [PHP] Forms and destroying values This issue comes over and over again.

Re: [PHP] forms usage in web pages
There's nothing wrong with multiple forms on a single page, as long as all id attributes in all elements are unique on the entire page, not just within the form. Just make sure that each form is self-contained with its own submit button and such. Only the form whose submit button is clicked will get submitted by the browser.

On Fri, April 21, 2006 7:45 am, William Stokes wrote: In PHP. Is it possible to point to a variable with the HTML form name by which it was posted from? The FORM name attribute was an add-on for Javascript client-side. It is not transmitted by HTTP. PHP never sees it. Or do I just have name the variables uniquely? Yes. Or you could just add ONE new INPUT in each form to tell you which FORM was used: INPUT TYPE=HIDDEN NAME=FORM VALUE=AddNew / Or you could have just ONE form and use buttons with name for your INPUTs: form name=irrelevant ... input type=submit name=AddNew value=Add / input type=submit name=DeleteOld value=Del / /form The button the user clicked on is sent as a variable with HTTP. EXCEPTIONS: If there is only ONE submit button, and if the user hits Enter (aka Return) instead of actually clicking on the button, then some browser do not send the button name/value. If you use JavaScript to do the submit, it's your problem to add whatever inputs you need in JavaScript to make things work... As well as anything in JavaScript works, anyway. Or you could have the FORMs have different ACTION attributes so you know which form sent the data because you have scripts dedicated to a specific purpose instead of some monolithic mess trying to be-all do-all end-all. Or you can use arrays in the NAME attributes to organize things in some cases -- probably not in this particular instance, but keep it in mind for INPUT elements within the same form. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Steve,
These can be a PITA. Here's how I've done it.
1. Create a function to determine which is selected:
function is_selected( $option_expression )
{
if ($option_expression)
{
$retval = selected;
}
else
{
$retval = ;
}
return $retval;
} // end of function is_selected
2. Build your list of selection, in this case a list of classifications
fetched from a database;
$option_class is the variable holding the list of options:
$sql = select * from class;
$result = mysql_query( $sql );
while( $row = mysql_fetch_array( $result ) )
{
$nClassKey = $row[nClassKey];
$cClass = $row[cClass];
$selectval = is_selected( $nClassKey == $nClass );
$option_class .= option value = \$nClassKey\
$selectval $cClass/option;
} // end while $row = mysql_fetch...
3. Then display it this way in the form:
Select name=nClass
? echo $option_class ?
/select
Hope this is helpful - Miles

The way I did:
# taking values from DB
$query = mysql_query(select * from VALUES)
$result = mysql_fet_array($query);
#create an array of all values of dropdow menu
$values = arra('value1', 'value2', 'value3', 'value4');
# create SELECT form using for loop
echo 'select name=category id=categoryoption selected=true
value=Option ValueOption Value/optionoption
value=line-/option';
for($i=0; $icount($values); $i++)
{
# if value from DB is equal to value in SELECT form set it as SELECTED
$selected = ($result['value_from_db'] == $values[$i]) ? 'SELECTED' : '';
echo 'option value='.$values[$i].' '.$selected.'
'.$values[$i].'/option';
}
echo '/select';

Re: [PHP] Forms on PHP
Refer to the following line numbers:
01 ?php
02 // Start of PHP code - Extract values from form.
03 /* Other values read */
04 $n=$_POST['n'];
05
06 // Pass the data from the form to lightcurve_csharp
07 $command=./lightcurve_csharp $a $i $e $lomega $bomega $lambda $n;
08 $result=`$command`;
09
10 $form_submitted=$_POST['form_sumbitted'];
11 if (isset($form_submitted)) {
12 if ($form_submitted) {
13 echo 'The form has been submittedbr';
14 unset($form_submitted);
15 }
16 } else
17 echo 'The form has not been submittedbr';
When the user first load the page, no data was posted. So there was no
$_POST['form_sumbitted'] available. Line 10 will cause $form_submitted to
contain the NULL value (I think). $form_submitted will evaluate to FALSE at
line 12. Thus it will not display any message.
By the way, by doing line 10, $form_submitted would have been set regardless
whether there is $_POST['form_sumbitted'], and line 11 will evaluate to TRUE
always. Thus you will never ever see the 'form not been submitted' message.
Anyway, when you posted for the first time, $_POST['form_sumbitted'] is
available. The 'The form has been submittedbr' message will be printed.
After that, when you press Reload button on the browser, the post data will
once again be sent from the user. (This is the behaviour of reloading a
posted page. In Internet Explorer there should be a message dialog box
asking the user whether to resend form data in order to refresh.) Reposting
the data during the reload means that there will be
$_POST['form_sumbitted'], thus once again the 'form hass been submitted'
message.
In order to prevent this from happening, you should do a header('Location:
success-page.php') on a successful submit. This is so that at the redirected
page, the user would not have resent data even if he press the Reload
button.
Hope this helps

Re: [PHP] Forms on PHP
PHPDiscuss - PHP Newsgroups and mailing lists wrote: I am new to this or any newsgroup in PHP, as well as PHP itself, so this question is probably rather elementary. I have a form which on clicking on the Submit button calls up a compiled program on the server that is executed and writes output to a file. This file is then read by the PHP script and passed on for other processes. Yikes! What if two guys surf to the same page AT THE SAME TIME? Is this all being taken care of? Or is this an admin page that only one guy ever uses, and he *KNOWS* not to run it in two different browsers at the same time? And you'll *NEVER* try to run it for testing while he's trying to run it for real? And... This scenario is rife with potential problems. When the page is first loaded, it knows that the Submit button has not been clicked, and after clicking the button it knows, which is of course what we want. The problem is that subsequently it always thinks the button has been clicked, even if the reload button on the browser has been clicked. When I hit re-load, you get back *exactly* the same thing I sent you last time. $_POST and everything. If you want to do something *different* then you need to keep a record of the fact that I already POSTed this data. For example, you could embed a http://php.net/uniqid in your FORM in a HIDDEN INPUT, and then store that in a database, and if I POST again, you can do whatever you want. Don't call that external program, and just read the file from the previous action but with an added notification that I'm reading old data, or send me a different output, or ... -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Refer to the following line numbers:

14 unset($form_submitted);
15 }
16 } else
17 echo 'The form has not been submittedbr';
When the user first load the page, no data was posted. So there was no
$_POST['form_sumbitted'] available. Line 10 will cause $form_submitted to
contain the NULL value (I think). $form_submitted will evaluate to FALSE at
line 12. Thus it will not display any message.
By the way, by doing line 10, $form_submitted would have been set regardless
whether there is $_POST['form_sumbitted'], and line 11 will evaluate to TRUE
always. Thus you will never ever see the 'form not been submitted' message.
Anyway, when you posted for the first time, $_POST['form_sumbitted'] is
available. The 'The form has been submittedbr' message will be printed.
After that, when you press Reload button on the browser, the post data will
once again be sent from the user. (This is the behaviour of reloading a
posted page. In Internet Explorer there should be a message dialog box
asking the user whether to resend form data in order to refresh.) Reposting
the data during the reload means that there will be
$_POST['form_sumbitted'], thus once again the 'form hass been submitted'
message.
In order to prevent this from happening, you should do a header('Location:
success-page.php') on a successful submit. This is so that at the redirected
page, the user would not have resent data even if he press the Reload
button.
Hope this helps
-Leon
Many thanks - at the top of the file I put in the code:
if ($_POST['submit'])
header('Location: .../submitted.php');
where further down in the form I have name=submit for the submit button.
This goes to a new page submitted.php. The code is in fact now at
http://proteus.as.arizona.edu/~csharp/lightcurved.php .
No doubt there is still a way of writing back to the original page after
the submit button has been clicked, but I can't see an easy way, so this
will have to do for now. A work-around is to do it in frames, and write
to a frame at the bottom so that it appears to be in the same page.

nl2br will give you back the correct formatting, but
will leave br/'s in the output.
I just went through this issue the other day, what I
found worked for me was:
htmlspecialchars('string'),ENT_NOQUOTES);
Note- check the available parameters for
htmlspecialchars. I used ENT_NOQUOTES because I wanted
to preserve the single and double quotes in my text.

My AOL, hotmail and other work addresses did not work. Can someone tell me why? Technically, To: is only supposed to allow one (1) email address. Assuming you are using sendmail or one of its popular drop-in replacements, they will support To: with multiple emails, but it's not RFC that they have to. So while I don't think it's the real problem, you're better off using Cc: headers in the optional fourth argument to http://php.net/mail to be standards-based. Most likely, however, the email you sent was flagged as spam by AOL and hotmail, but not yahoo. So the email got sent just fine, but they throw it out before you ever saw it. You can research how spam filters work to make your email look less like spam and tray again.

KAM What I have is an issue with posting forms with Dynamic ListBoxes.
KAM What happens is when you fill the form out, and hit submit, it validates the

KAM an error. All the textfields have all the information and the Static
KAM ListBoxes have all the information they filled out... But if the user
KAM selected a STATE (which is pulled dynamically) it will reset this box to the
KAM default setting.
It will reset it when the page reloads with the error message, yes?

You already have the preselected variable in your function, so why not
just pass in whatever the user previously selected back to it again?

Well, like I say, you've pretty much written it there. You need a loop which outputs
one line on each iteration -- the body of the loop will look something like:
echo fname$i = {$_POST['fname'][$i]}
. flab$i = {$_POST['flab'][$i]}
. fplc$i = {$_POST['fplc'][$i]}
There's any number of ways you could write the loop so that $i has the approriate
value on each iteration, but a for() loop would probably be the conventional one.

Do you really want a variable called $fname0 and another $fname1 and so
on, or do you just want this output? It seems to me that you probably
want the latter, so you need only walk through your array:
foreach ( array_keys($_POST[fname]) as $k )
{
print fname$k = {$_POST[fname][$k]} ;
print flab$k = {$_POST[flab][$k]} ;
print fplc$k = {$_POST[fplc][$k]}br\n ;

If I understand your question correctly it sounds like you want to populate a database on Server A with data residing in a database on server B via a form hosted on server A *grin*. Obviously this is tedious, and if there are a lot of entries then I would suggest writing a script to populate and submit the form automatically. If you are lucky everything will be done via HTML GET method (URL parameters); however, it is more likely that it uses the POST method.

Re: [PHP] Forms
As I mentioned already you would be best not using Javascript and
performing the submission via PHP. I wrote the following snippet in the
past to do something similar to what you are asking. Study it and see if
you can adapt it to your own needs. You should be able to loop on the
form submission but you may want to disable script time limit if you
expect that this will take a while.
function submitForm( $host, $path, $data )
{
$headerString =
'POST '.$path.' HTTP/1.0' .\r\n
.'User-Agent: Lynx ;)' .\r\n
.'Host: '.$host .\r\n
.'Accept: */*' .\r\n
.'Content-type: application/x-www-form-urlencoded' .\r\n
.'Content-length: ';
$postData = '';
foreach( $data as $key = $value )
{
$postData .= urlencode( $key ).'='.urlencode( $value ).'';
}
$postData = ereg_replace( '.$', '', $postData );
$headerString .= ''.strlen( $postData ).\r\n\r\n;
$headerString .= $postData.\r\n;
$content = sendRequest( $host, $headerString );
$content = implode( \n, $content );
echo 'CONTENT'.\n\n.$content.\n\n;
}
function sendRequest( $host, $header )
{
$fp = fsockopen
(
$host,
80,
$errno,
$errstr,
30
);
$data = '';
if( !$fp )
{
echo Error: $errstr ($errno)\n;
}
else
{
fputs( $fp, $header );
while( !feof( $fp ) )
{
$data .= fgets( $fp, 128 );
}
fclose( $fp );
}
return explode( \n, $data );
}
Cheers,
Rob.

If I understand your question correctly it sounds like you want to
populate a database on Server A with data residing in a database on
server B via a form hosted on server A *grin*. Obviously this is
tedious, and if there are a lot of entries then I would suggest writing
a script to populate and submit the form automatically. If you are lucky

RE: [PHP] Forms and PHP
Not sure why you don't want to submit the form. But if you really really don't want to submit the form then you have to use javascript. If you're willing to submit the form, then this is relatively simple, depending on how you want to display the data. if you're willing to submit, then step through the field that has the data, one word at a time (maybe explode the string on (space)) and compare the word to your dictionary. if the word is misspelled, then add it to an array, or do some action -Original Message- From: Jason Giangrande [mailto:[EMAIL PROTECTED] Sent: Saturday, July 19, 2003 8:37 PM To: [EMAIL PROTECTED] Subject: [PHP] Forms and PHP I have a question about forms and PHP.

Re: [PHP] Forms and PHP
This is done with javascript... without getting too off topic...

No, in your first form you have code like
Well almost. I realised whilst trying to get to sleep last night that
there's a problem with this. In the first form you need:
?php
if ((!isset($_POST)) || (!isset($_POST['foo']))) {
$foo = set default value here;
$action = form2.php;
} else {
$foo = $_POST['foo'];
$action = results.php;
}
?
form method=post action=?php echo $action;?
input type=text name=foo value=?php echo $foo;? /
...
/form
This way you won't get a circular dependency. However, it means that you'll
need to provide some other way of amending the details on form2 if it's a
requirement.
and in the second form you have:
form method=post action=form1.php
input type=hidden name=foo value=?php echo $_POST['foo'];? /
...
/form

When the submit button in this form is clicked it updates the database with no problems and displays a link - linking back to page1.php (I have decided not to use redirect). How do load the page and fill all the text boxes with the information that was already written - because this information (from page1.php, first form) has not been saved to the database yet.
