refering as previous question here HTML Generator: Convert HTML to PlainText and put in a textbox using PHP

Now i got some problems even if the reply produce the expected result.

I got these 3 pages:

Page1.php

// This page contain two columns, one for the form that take the variables, and other one that contain the iframe that must to display the plaintext

Page2.php

// Cutted code that take $_GET variables and store in $_SESSION $html = file_get_contents('page3.php'); echo '<textarea readonly style="border:none;resize:none" rows="50" cols="116" value="'. $html .'"></textarea>';

Page3.php

// This is the file page3.php that must to be in plaintext, but first it must take the variables from $_SESSION and complete the code

Now I get the plain text file but the variables aren't passed since i've stored them in session. i got $var instead of the value.

And the textbox displays only half of the file, not showing the <link> and the whole <style> tags.

<textarea> does not have value.

You need to echo that variable inside the tags.

$html = "Text here"; echo '<textarea readonly style="border:none;resize:none" rows="50" cols="116">'. $html .'</textarea>';

"it must take the variables from $_SESSION and complete the code"

Also note that you are using sessions. Make sure the session was started having session_start(); at the top of that page and for any other pages that may be using sessions.

Example:

session_start(); if(isset($_SESSION['var'])){ $_SESSION['var'] = "var"; } else{ echo "Session is not set."; }

N.B.: Make sure you are not outputting before header.

Consult the following on Stack if you get a headers sent notice/warning:

Add error reporting to the top of your file(s) which will help find errors.

<?php error_reporting(E_ALL); ini_set('display_errors', 1); // Then the rest of your code

Sidenote: Displaying errors should only be done in staging, and never production.

Test example which proved successful, echoing var inside <textarea>:

<?php session_start(); if(isset($_SESSION['var'])){ $_SESSION['var'] = "var"; $var = $_SESSION['var']; } else{ echo "Session is not set."; } // $html = "Text here"; $html = $var; echo '<textarea readonly style="border:none;resize:none" rows="50" cols="116">'. $html .'</textarea>';

Edit:

Base yourself on the following model to assign GET arrays to sessions arrays.

<?php session_start(); $_GET ['lb1'] = "lb1"; $lb1 = $_GET ['lb1']; $_GET ['lb1'] = $_SESSION["lb1"]; $_SESSION["lb1"] = $lb1; //echo "Hey LB1 " . $lb1; $lb1_session = $lb1; $_GET ['lb2'] = "lb2"; $lb2 = $_GET ['lb2']; $_GET ['lb2'] = $_SESSION["lb2"]; $_SESSION["lb2"] = $lb2; //echo "Hey LB2" . $lb2; $lb2_session = $lb2; $html = $lb1_session . "\n". $lb2_session; echo '<textarea readonly style="border:none;resize:none" rows="50" cols="116">'. $html .'</textarea>'; ?> <a href="check_get_sessions.php">Check GET sessions</a>

check_get_sessions.php

<?php session_start(); if(isset($_SESSION['lb1'])){ $lb1_session = $_SESSION['lb1']; echo $lb1_session; } if(isset($_SESSION['lb2'])){ $lb2_session = $_SESSION['lb2']; echo $lb2_session; } $html = $lb1_session . "\n". $lb2_session; echo '<textarea readonly style="border:none;resize:none" rows="50" cols="116">'. $html .'</textarea>';

That's the best I can offer you.

Doing $html = $lb1_session . "\n". $lb2_session; you can use "\n" as seperators between each variable to be echo'd. Or, <br> if you want; the choice is yours.

The above assigns the $html variable to chained variables. You can add the others that may need to be added $lb3, $lb4, $lb5 etc.

Good luck! (buon fortunato)

Thanks, that stupid error is gone now the file display correctly. Using error reporting i see that the variables isn't setted. there is a point in your reply that i can't undestand, figure the variables to be passed is a total of 8, how can i use $html = $var;?
@andreaem You're welcome. I used $var as an example variable taken from the session array, which in turn is then assigned to the $html variable, in turn echoing in the textarea. You stated in your question that you were using sessions, so I made up a quick test file to show you an example.
Thanks, should it work, i've replaced var with my variable name and no error is reporting. The point is that i got the full file as plain text but, this file contain some variables that must to show his values before outputting as plaintext, and now i got the $var1 instead of "somevalue", there is anyway to set the variables first of put content in the textbox? Maybe a visual example can explain better link
@andreaem well I'd keep what you have now for $html = file_get_contents('page3.php'); and use what I posted in my answer about echo '<textarea readonly style="border:none;resize:none" rows="50" cols="116">'. $html .'</textarea>';. Hard to say exactly about what you meant as "this file contain some variables that must to show his values before outputting" - You may need to use a heredoc php.net/manual/en/… or nowdoc php.net/manual/en/…
follow my link in previous reply, will reach the page i'm working on, i'm italian so maybe i can't explain what i mean. in the page completing the form with random values and clicking generate it will display the page code, in this page you will see that we have $lb1,$lb2,$lb3 etc.. i must to assign a value to this variables first of showing the output, but even if i do, it will show $lb1 cause it's the file original content
