If you run this in a browser you can see the form. I want to clarify how could that be happen the form is inside the if statement. Is there any way you can hide html code in PHP. The html code will be executed if the "if" statement is true.
<?php
require "../utility/connection.php";
$submit = true;
if(isset($_POST['submit'])){
$query = mysqli_query($connect, 'SELECT * FROM email_accounts');
}else{
}
if($submit = true){?>
<form method="post" action=" .<?php echo $_SERVER['PHP_SELF']; ?> ">
<label for="subject">Subject:</label>
<input type="text" id="subject" name="subject" value="<?php echo $subject; ?>" />
<br />
<br />
<label for="message_body">Say something:</label>
<textarea id="message_body" name="message_body"><?php echo $msg_body;?></textarea>
<br />
<input type="submit" id="submit" name="submit" value="Send Email" />
</form>;
<?php
}
?>

First, your 'if' statement is wrong - you have used a single '=', which means it assigns the value true to $submit and then tests it, finding it to be true and executing the block that follows. Here are some options that will work:
if($submit == true) {
if($submit === true) {
if($submit) {
The second reason your form will display is that you have set $submit to true on the second line of the script, and you don't appear to be setting it anything else elsewhere in the code.

Wow your great.
I change the initial value of submit to false. I also change the "if" statement to == but the form still showing.
Thanks for your help.

Just to clarify aswell:
= is an assignment operator.
== is the comparison operator as mentioned above.
=== is another comparison operator I call identity, which checks for equality AND type.
As PHP is not strongly typed, a variable can change types dynamically at runtime.
Example:
$a = 2;
$b = "2";
A comparison would be like this:
if($a == $b)
{
}
..would be TRUE, as they have the same value, but one is an integer and one is a string.
if($a === $b)
{
}
.. would be FALSE, because they have matching values but different types!
For me, understanding this in the beginning helped me to write reliable condition tests for websites and applications.

PHP doesn't run in a browser, it runs in the web server. If you open a PHP file directly in a browser (by File->Open...) instead of loading it from a server the PHP code won't get executed.

I run this stuff using my local web server xampp in localhost.

I think you might have a syntax error.
if you have to check something, then the if statement should be:
if($submit == true)
if($submit = true) -> is setting submit to true not checking.
Hope this helps.

This is an odd error and I hope someone has seen it before.
I have a script that is called from other scripts. It also runs from the commandline and is used to ftp files to various destinations. One is to a google upload site and it looks to work 2 out of 3 runs with one time reporting this error
Warning: ftp_put(): '': command not understood.
Using a google search, I have found reference to "ftp_put(): 'STOR':" errors but nothing on the empty string I have.
What else gets me is this does not fail always, just once in a while. I can use the same parameters too...sometimes it fails but usually it is good.
ideas?

Reading the comments in the PHP Manual ... http://php.net/manual/en/function.ftp-put.php[^] you are not the only one to suffer. In the comments various possible solutions are suggested.
Let us know which, if any, provides a better answer.

in your form tag one attribute is missing. Without that attribute browser wont upload file
enctype="multipart/form-data"

I think this belongs better in the forum as I believe the problem to be on the PHP side. What I'm doing is creating a table dynamically that has some JavaScript function calls in it (well I'm trying to). The page is displaying ok in Chrome and Firefox but IE is complaining about it and not displaying at all. However in Chrome and Firefox it's not "working" just displaying right. this is the code I'm trying to use...
$display_string .= "<td><a href='javascript:choice('".$row .$col ."')'><img src='images/o.jpg' border=0 height=100 width=100 name='" .$row .$col ."' alt='Open'></a></td>";
When you hover over one of the cells on the loaded page you see javascript:choice(. It should read something like javascript:choice(A3) If I do an inspect element with chrome I get
<img src="images/o.jpg" border="0" height="100" width="100" name="B2" alt="Open"> so it appears the issue is in the creation of the javascript call?
Thanks in advance!!

You need to properly match up your quotes - you used a single quote for href= and then the closing quote was just inside the javascript function. Try this:
$display_string .= "<td><a href=\"javascript:choice('{$row}{$col}')\"><img src='images/o.jpg' border=0 height=100 width=100 name='{$row}{$col}' alt='Open'></a></td>";
I've replaced the outer single quotes with escaped double quotes. I've also put the $row and $col variables into the string so that the '.' operator is not required, but that's just my personal preference.

Now I see what I did wrong in my other version, I forgot the escape character... the joys of learning new languages. Thanks, it seems to be working now.
Putting a variable inside {} adds it to a string? I didn't know that. 
I really appreciate the help!!

At the moment, I have index.php located at the root. I want to have it parse all my URLs and delegate the workload to the correct code (via URL rewriting). I may be a bit nit-picky, but I'd like to know if there's an elegant solution to neatly separating the request URL and the key-value pairs of the query?
My index.php looks like this:
<?php
header('Content-Type: text/plain; charset=utf-8');
echo 'Debug Output';
echo "\n\n";
echo 'Request ($_SERVER["REQUEST_URI"]): "'.$_SERVER['REQUEST_URI'].'"';
echo "\n";
echo 'Request ($_GET["request"]): "'.$_GET['request'].'"';
echo "\n";
echo 'd="'.$_GET['d'].'"';
echo "\n";
echo 'e="'.$_GET['e'].'"';
echo "\n";
?>
If I give it some URLs, they produce the corresponding outputs:
- mysite.com/a/b/c?d=1&e=2&request=3
Debug Output
Request ($_SERVER["REQUEST_URI"]): "/a/b/c?d=1&e=2&request=3"
Request ($_GET["request"]): "3"
d="1"
e="2" - mysite.com/a/b/c?d=3&e=4
Debug Output
Request ($_SERVER["REQUEST_URI"]): "/a/b/c?d=3&e=4"
Request ($_GET["request"]): "a/b/c"
d="3"
e="4"
$_SERVER["REQUEST_URI"] includes everything after mysite.com including the raw query string, and $_GET["request"] will not return the requested URL minus the query string if there is a key named request.
I could parse the value of $_SERVER["REQUEST_URI"] myself, but I'd like to use built-in functionality before coding around the problem.
My GUID: ca2262a7-0026-4830-a0b3-fe5d66c4eb1d 
Now I can Google this value and find all my Code Project posts!

$_SERVER["QUERY_STRING"] will give you the query string. (I forget if it includes the ? or not.) Picking off everything prior to the first ? (i.e. the URL part) isn't too hard.

Interestingly enough, I get all the pieces of the request neatly delimited by ampersands.
mysite.com/a/b/c?d=1&e=2&request=3
Debug Output
Request ($_SERVER["REQUEST_URI"]): "/a/b/c?d=1&e=2&request=3"
Request ($_GET["request"]): "3"
Request ($_SERVER["QUERY_STRING"]): "request=index.php&request=a/b/c&d=1&e=2&request=3"
d="1"
e="2"
mysite.com/a/b/c?d=1&e=2&request=%26+%3F
Debug Output
Request ($_SERVER["REQUEST_URI"]): "/a/b/c?d=1&e=2&request=%26+%3F"
Request ($_GET["request"]): "& ?"
Request ($_SERVER["QUERY_STRING"]): "request=index.php&request=a/b/c&d=1&e=2&request=%26+%3F"
d="1"
e="2"
Although the key-value pairs remain encoded, I guess it's still better to just use explode to get the key-value pairs first and then explode the resulting items to get the keys and values.
