Pete
Once again, thank you for your help.
I was able to get it to work, I did not understand the browser differences
either, but on my testing server on IE, it worked as I wanted but not on
anything else. I chopped out most of the code and ended up with this:
if ( isset($_POST['submit']) ) {} else {
print "<form action=\"phpForm3.php\" method=\"POST\">\n";
if ($Recordset1) {
print "<table width=200 border=1>\n";
print "<th> </th>\n";
print "<th> State </th>\n"; //2 fields in Counties table, State and County
print "<th> County </th>\n";
print "</tr>\n";
//create table
$i = 0;
while ( $row = mysql_fetch_array($Recordset1) ) {
$i++;
print "<tr>\n";
print "<td><input type=\"checkbox\" name=\"county$i\"
value=\"$row[name]\"></td>\n";
echo "<td>{$row['state_id']}</td>\n";
echo "<td>{$row['name']}</td>\n";
echo "</tr>\n";
}//end while
print "</table>\n";
} else {
echo("<P>Error performing query: " .
mysql_error() . "</P>");
}
print "<input type=\"hidden\" name=\"counties\" value=\"$i\"/>\n";
print "<input type=\"submit\" name=\"submit\" value=\"Go\"/>\n";
}
?>
Again, thank you.

If you would allow me to show you a little easier way of doing this.
if ( !isset($_POST['submit']) ) {
echo '<form action="phpForm3.php" method="POST">';
if ($Recordset1) {
echo <<<HEADER
<table width=200 border=1>
<tr><th> </th><th> State </th><th> County </th></tr>
HEADER;
while ( $row = mysql_fetch_array($Recordset1) ) {
echo <<<ROW
<tr>
<td><input type="checkbox" name="county[]" value="{$row['name']}"></td>
<td>{$row['state_id']}</td>
<td>{$row['name']}</td>
</tr>
ROW;
}//end while
echo '</table>';
} else {
echo '<p>Error performing query: '.mysql_error().'</p>';
}
echo '<input type="submit" name="submit" value="Go" />';
}
Now, the main thing I want you to see is the line for the country checkbox'es
The county[] turns the submitted values into an array. So, in the processing
script, you would do this.
<?php
...
if ( !empty($_POST['county'])
foreach ( $_POST['county'] AS $id => $name )
echo "{$id} {$name}\n";
...
?>
Hope this clears things up for you a little.
Enjoy.
Jim

In a weird twist, I have/had the script working, but again it is not
working in FF or Chrome. This is a link to the first page which runs you
through the pages.
I have the submit to trigger upon change so there is no submit button. This
works in IE7. If I add a submit button, it does not work in any of them.
I am wondering if this is more a problem with the html.
http://www.assessmentappeallawyer.com/forum_state.php
This is the code for the first processing page
if ( !isset($_POST['submit']) ) {
echo '<form action="forum_delete.php" method="POST">';
if ($Recordset1) {
echo <<<HEADER
<table width=200 border=0>
<tr><th> </th><th> State </th><th> County </th></tr>
HEADER;
while ( $row = mysql_fetch_array($Recordset1) ) {
echo <<<ROW
<tr>
<td><input type="checkbox" name="county[]" value="{$row['name']}"></td>
<td>{$row['state_id']}</td>
<td>{$row['name']}</td>
</tr>
ROW;
}//end while
echo '</table>';
} else {
echo '<p>Error performing query: '.mysql_error().'</p>';
}
echo '<input type="submit" name="submit" value="Select" />';
}
?>
****This is the code for the second processing page.
<?php
if ( !empty($_POST['county']))
foreach ( $_POST['county'] AS $id => $name )
echo 'You have selected '. " {$name}".'<br />';
$totalRows_county_result_net= "($totalRows_county_result) + (1)";
echo "[$totalRows_county_result_net]";
echo "$totalRows_county_result";
?>
</div>
<!--eo center-->
<?php
$name=$_POST['name'];
echo 'You have selected'."$name";
?>
<?php
mysql_free_result($county_result);
?>
Again, thank you for any input.

I think it may have to do with HTML, or the fact that IE is "helping"
you with your coding... where FF and Chrome are usually more
"literal" (yet better IMO). Also, the fact that "submit" has not been
defined.
try adding:
<input type="submit" name="submit" value="submit" style="display:
none;" />
This *SHOULD* give you the submit button, but the style is "hidden" now,
so it shouldn't show, but it will fire off the "submit" action... make
sure it is in between the <form></form> tags though.

Thank you for your reply, I had inserted a submit button prior, but it did
not work. I tried your suggestions and got the same result. I am not
seeing anything in the html that should be causing the hick-up, but given
the php is run on the server as Peter pointed out, browser issues with php I
have not really encountered before.
I can live with a submit button, but living with one that does not work...
Thank you for your input, if you see anything else that seems amiss, please
let me know.

the <form onchange="submit"> as far as I know, isn't a standard/valid
html attribute... so I would remove it altogether.
http://www.w3schools.com/tags/tag_form.asp
and try on the <select ... onchange=""> to be
<select .... onchange="document.forms["Form1"].submit();">
where Form1 is the id of the form (so add that to the <form...>
<form id="Form1" ... >
try that... (i haven't been testing... my fault... but I am in the midst
of work right now to really test it out)
good luck!

I don't think this is a bad idea at all, in general. This is pretty
much what TextMate does when you use snippet insertion. For editors

the structure of what i'm doing before filling in all the details.

When I'm writing code in a language I know, I use either Vim, Kate, or
Eclipse. But when I'm learning a language I use an environment with no
syntax highlighting or code completion. It is in these cases that the
close-then-fill coding style helps. Also, I've many times had to SSH
into a server and change HTML or PHP code in the half-VIM that ships
with CentOS and Debian, which does not support syntax highlighting. So
the style has real-world advantages.

2:1 is excessive. I only comment where the code is not explicitly
clear, or at the beginning of each code block of a long if / elseif /
elseif chain. And I comment the close parenthesis to know what it
closed.

Sometimes I have to touch a live site, in fact _most_ of the work I do
is for small accounts that don't have a test environment. I can often
write a test page with a security-by-obscurity filename, but relying
on the interpreter is a habit that I cannot afford.

This question will probably reveal my lacking knowledge of the
fundamentals, but I'm a go for it anyway:
When you use a $_SERVER variable, is a query made to the server to get
the information or is it just sitting in a variable all ready to go?
Reworded, is there any efficiency gained by storing the data in a
"local" variable if it's going to be used many times in the script?
My experience with jQuery has taught me to store $(objects) in local
variables if they're going to be used repeatedly because the DOM is
queried every time a jQuery object is generated, so I'm wondering if a
similar logic applies.
Example:
if ($_SERVER['SCRIPT_NAME'] == 'how.php')
// do stuff
if ($_SERVER['SCRIPT_NAME'] == 'why.php')
// do other stuff
vs.
$script_name = $_SERVER['SCRIPT_NAME'];
if ($script_name == 'how.php')
// do stuff
if ($script_name == 'why.php')
// do other stuff
Cheerios,
Marc

Marc,
$_SERVER is an array and it should have all the information. I do not know
the answer for the latter part of your query.

$_SERVER is just a prepopulated superglobal array that is created
at runtime. When the script is executed via the web, PHP and the web
server (for example, Apache) generate numerous environment values as
directed by their configuration.
The quickest way to learn about this in more detail is to use it's
nickname in Google: EGPCS. The actual configuration directive is
variables_order, but many folks - particularly the PHP3/4 and very
early PHP5 - will be more familiar with the nickname, which is an
acronym for the default order of superglobals: Environment, Get, Post,
Cookie, Server.

Thanks for the clear answer.

This is something I actually do understand. I was wondering if the
code running on the server had to query the server for the information
every time a $_SERVER var was referenced, but like Daniel explained,
the contents of the $_SERVER array are populated at runtime and so no
further "hey server, what version of apache are you running?"
questions need to be asked of it.

No, it wasn't. If you look at where I pass in parameters, I have a
$parameter-> value bound as value of the parameter, which is wrong. It
should be just $parameter. I corrected my code (after digging for the
larger part of a week), and now it's working. I guess this had to do
with my very short-lived experience with PHP - less than 40 hours, if
I put everything ever spent on PHP together.

Is there a way to make this syntax:
$checking_answer = $answer_reference_2;
Equal to:
$checking_answer = $answer_reference_ . ($i + 1);
(where $i = 1)
making $checking_answer take on the value of $answer_reference_2 ?
I am trying to develop a web app quiz and I need to test the users answers.
