problem is you have a mix of HTML and PHP

you have to use the <?php and ?> tags to show what is PHP

<?php

?>
<form name="" method="post" action="<?php echo $_SERVER['PHP_SELF'] ?>">
<p>
<?php
// php start                    

                $sql = "SELECT * from pages where username = '$_SESSION['user']' AND title='$_GET['id']' ";
                $result = mysql_query($sql, $conn);
                $row = mysql_fetch_assoc($result);
// php end
?>                   

<input type="text" name="title" value="<?php echo $_GET['id'] ?>"><br><br>

No sorrry miss understanding, its all in a function and the HTML is being echoed out. So i think i need to concatenate the php so it is not echoed out as $_SERVER['PHP_SELF'].

If it makes sense?

if you are 'echoing it out'
you have to use
echo "something";
if you dont use echo, then you have to use plain HTML,
and escape from php using ?>

No i am using that i will give an example;

function eample()
{
echo '<html><body>';
echo '<td align="center"><form action="$_PHP_SESLF">';

rather than echoing the page like index.php it is actually echoing $PHP_SELF. I am having this problem with things like

echo'<input type="text" value="$row['value']">';

do you see what i mean?

Read the manual dealing with strings.

Single quotes (') will not have the PHP engine go through and parse it.
Double quotes (") will have the PHP parsers parse the string.

So:

echo '<td align="center"><form action="$_PHP_SELF">';

Will echo out:

<td align="center"><form action="$_PHP_SELF">

and

echo "<td align='center'><form action='$_PHP_SELF'>";

will echo out:

<td align='center'><form action='page.php'>

Now, your post title was "Concatenation" which would look like:

echo '<td align="center"><form action="' . $_PHP_SELF . '">';

will echo out:

<td align="center"><form action="page.php">

Make sense? See here for more help
