Page will not successfully include()

[stickynote427]

I have a tutorials page on my site. A parameter in the URL determines the tutorial displayed, and if a "code" parameter is set, then that example for the tutorial will be displayed instead.

 

However, when I try to include() the example file, my entire page does not load; I'm assuming because include() is obviously run in PHP, as well as the file starting out with some PHP code.

 

Here's what I have at the top of my tutorials page:

 

<?php

if (isset($_GET['t'])) { //if a tutorial is specified
if (isset($_GET['code'])) { //check if the example should be shown
include('howto/'.$_GET['t'].'/code'.$_GET['t'].'.txt'); //include the example file
}
else { //if the example file should not be shown
include('howto/'.$_GET['t'].'/tut'.$_GET['t'].'.txt'); //include the tutorial file
}
echo("<a href=\"http://blakechesney.com/p/howto\">Return to the main how-to page</a>"); //echo navigation back to the main page
}

else {
// perform actions related to the main page; probably irrelevant to my problem
?>

 

When the "code" parameter is set, though, the page only loads up to the point until I want to include() the example file.

 

Any ideas?

 

Thanks.

Try using the require() function as it has better error reporting. Also if you are planning to store the file data in a variable you can alternatively use the file_get_contents() function. The cause - the file does not exist. Be sure the path is relative of the php script and try to follow the path via ftp yourself.

[stickynote427]

Using require() unfortunately gives me the same result.

 

Using file_get_contents() displays the rest of the page like I want it to, but the content of the example file is still not included.

You need to turn error reporting and display errors on.

 

Put this at the very tp of your script.

 

<?php ini_set('display_errors','1') ; error_reporting(E_ALL) ;?>

[stickynote427]

Thanks.

 

This is what I get:

 

Warning: mysql_connect() [function.mysql-connect]: Access denied for user 'root'@'localhost' (using password: NO) in /var/www/html/mysql/test.php  on line 4

 

I have tried different usernames and passwords as well and those do not work, either.

You haven't posted any code that connects to any databases. That error would seem unrelated.

[stickynote427]

I'm confused. This is all of the code I have in my file:

 

<?php ini_set('display_errors','1') ; error_reporting(E_ALL) ;?>

<?php
$con = mysql_connect("localhost","root","");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

if (mysql_query("CREATE DATABASE my_db",$con))
  {
  echo "Database created";
  }
else
  {
  echo "Error creating database: " . mysql_error();
  }

mysql_close($con);
?>

[trq]

How does this relate to the code in your first post and then again to your question?

 

Are you with us?

[cwarn23]

Try making your connect line the following

$con = mysql_connect("localhost","root","",true);

[trq]

Try making your connect line the following

$con = mysql_connect("localhost","root","",true);

 

Firstly, what does that have to do with the original question?

 

Secondly, your advice would do NOTHING at all in relation to an access denied error either.

Oh, lord. I apologize. I'm also having problems with MySQL and did not realize that this was not where I was trying to get help with MySQL.

 

I added the PHP code that thorpe provided earlier to the CORRECT file this time. Here is the error I receive:

 

Parse error: syntax error, unexpected T_CONSTANT_ENCAPSED_STRING, expecting ')' in /var/www/html/pages/howto/2/code2.txt  on line 6

 

Again, I'm sorry about my mistake.

[cwarn23]

Php must be executing the text as code. Try the following as your include.

echo file_get_contents('howto/'.$_GET['t'].'/tut'.$_GET['t'].'.txt');

[stickynote427]

Okay, now I receive:

 

Warning: file_get_contents(howto/2/tut2.txt) [function.file-get-contents]: failed to open stream: No such file or directory in /var/www/html/pages/howto.txt  on line 8

[cwarn23]

Isn't it obvious, the file does not exist. So I would suggest that you make sure the specified path is NOT a fake url and to make sure it exists. If you need a fake url you must specify the full 'http://domain.com/folderetc'.

Okay, now I receive:

 

Warning: file_get_contents(howto/2/tut2.txt) [function.file-get-contents]: failed to open stream: No such file or directory in /var/www/html/pages/howto.txt  on line 8

[greatstar00]

the above error means the file does not exist, so try to give a valid file

[stickynote427]

Alright, well, I tried this:

 

echo file_get_contents('http://example.com/pages/howto/'.$_GET['t'].'/tut'.$_GET['t'].'.txt');

 

And I get this error message:

 

Warning: file_get_contents(http://example.com/pages/howto/2/tut2.txt) [function.file-get-contents]: failed to open stream: HTTP request failed! in /var/www/html/pages/howto.txt  on line 8

 

And went to http://example.com/pages/howto/2/tut2.txt and I can see the file fine.

[cwarn23]

Replace the example.com with your real domain.

Alright, well, I tried this:

 

echo file_get_contents('http://example.com/pages/howto/'.$_GET['t'].'/tut'.$_GET['t'].'.txt');

 

And I get this error message:

 

Warning: file_get_contents(http://example.com/pages/howto/2/tut2.txt) [function.file-get-contents]: failed to open stream: HTTP request failed! in /var/www/html/pages/howto.txt  on line 8

 

And went to http://example.com/pages/howto/2/tut2.txt and I can see the file fine.

This likely means that you have url_wrappers disabled. Most hosts will not allow you to use urls to include or open files.

[cwarn23]

Try the following:

echo file_get_contents('http://blakechesney.com/pages/howto/'.$_GET['t'].'/tut'.$_GET['t'].'.txt');
