display php code

[ecabrera]

hello i need help on displaying php code on my website so people can come and just copy it but it wont let me display it

[trq]

What exactly is the problem?

[MasterACE14]

I think you're after highlight_string()

[ecabrera]

ok im using highlight_string() to output a bit of php code but and it does but returns a value of 1

 

<?php
if ($_GET['view']){

$id = $_GET['view'];

require "scripts/connect.php";
$query = mysql_query("SELECT * FROM php WHERE id='$id'");
$rows = mysql_fetch_assoc($query);

$title = $rows['title'];
$body = $rows['body'];
        $code = highlight_string($rows['code']);

mysql_close();
}

?>
<div id="codetitle">
<?php echo $title;?>
</div>
<p id="body"><?php echo $body;?></p>
<?php

if($code){
echo "<div id='codeBox'>$code</div>";
}else
{

}
?>

[MasterACE14]

        $code = highlight_string($rows['code'], true);

[ecabrera]

ok thanks

[ecabrera]

ok so i'm saying if there is no code dont dispay that box but if there is display

 

<?php
if(!$code){

}else
{
echo "<div id='codeBox'>$code</div>";
}
?>

 

this displays it no matter if there is code or not

[MasterACE14]

if($code == '')

 

or...

if(empty($code))

[ecabrera]

still displaying

[trq]

We need to see more code.

[ecabrera]

<?php
if ($_GET['view']){

$id = $_GET['view'];

require "scripts/connect.php";
$query = mysql_query("SELECT * FROM php WHERE id='$id'");
$rows = mysql_fetch_assoc($query);

$title = $rows['title'];
$body = $rows['body'];
        $code = highlight_string($rows['code'], true);

mysql_close();
}

?>
<div id="codetitle">
<?php echo $title;?>
</div>
<p id="body"><?php echo $body;?></p>
<?php
if($code == ''){

}else
{
echo "<div id='codeBox'>$code</div>";
}
?>

<?php
if (isset($_GET['view']) && !empty($_GET['view'])){ // avoid error variable doesn't exist

$id = $_GET['view'];

require "scripts/connect.php";
$query = mysql_query("SELECT * FROM php WHERE id='$id' AND LENGTH(code)");
   if ( mysql_num_rows($query) )
   {
       $rows = mysql_fetch_assoc($query);

      $title = $rows['title'];
      $body = $rows['body'];
       $code = highlight_string($rows['code'], true);
   }
mysql_close();
}

?>
<div id="codetitle">
<?php echo $title;?>
<>
<p id="body"><?php echo $body;?></p>
<?php
if ( isset($code) )
{
echo "<div id='codeBox'>$code<>";
}
?>

[ecabrera]

stilll displays

[ecabrera]

this was after i add        $code = highlight_string($rows['code'], true); before it use to work

[Andy-H]

That's because

echo highlight_string('', true);

outputs

<code><span style="color: #000000"></span></code>

 

Did you use the exact code I posted? It should work.

[ecabrera]

yes but the box still displays

[Andy-H]

<?php
if (isset($_GET['view']) && !empty($_GET['view'])){ // avoid error variable doesn't exist

$id = $_GET['view'];

require "scripts/connect.php";
$query = mysql_query("SELECT * FROM php WHERE id='$id' AND LENGTH(code)");
   if ( mysql_num_rows($query) )
   {
       $rows = mysql_fetch_assoc($query);

      extract($rows, EXTR_SKIP);
   }
mysql_close();
}

?>
<div id="codetitle">
<?php echo $title;?>
<>
<p id="body"><?php echo $body;?></p>
<?php
if ( isset($code) && !empty($code) )
{
echo '<div id="codeBox">'. highlight_code($code) .'<>';
}
?>

??

[ecabrera]

i tryed and i makes it worse thanks for helping though

[Andy-H]

lol how does it make it worse? Note the <>, I think thats something to do with PHPFreaks quote button.

[PaulRyan]

This will work I think, untested.

 

<?PHP

  //### If view does not exist, show error message
  if(!isSet($_GET['view'])) {
    echo 'You have not selected any code to view.'; 
    exit;
  }

  //### Make $_GET['view'] an integer
  $id = intVal($_GET['view']);

  if(!$id) {
    echo 'Invalid ID to get code.';
    exit;
  }

  //### Include the DB connection
  include("scripts/connect.php");

  //### Make our query
  $query = "SELECT `title`,`body`,`code` FROM `php` WHERE `id` = {$id}";

  //### Execute our query
  $doQuery = mysql_query($query);

  //### If we do find any match, display error, else disaply code
  if(!mysql_num_rows($doQuery)) {
    echo 'We could not find the code you were looking for.';
    exit;
  } else {

    //### Assign data fetch to $result
    $result = mysql_fetch_assoc($doQuery);

    //### Echo the code title and body content
    echo "<div id='codetitle'> {$result['title']} </div>";
    echo "<p id='body'> {$result['body']} </p>";

    //### If code exists display it, if it doesn't display a message
    if(!empty($result['code'])) {
      echo "<div id='codeBox'>{$code}</div>";
    } else {
      echo 'No code to display';
    }
  }
  
?>

 

Try it out, tell me how it goes.

 

Regards, PaulRyan.

[ecabrera]

works but does not display the code for the ones that have should i add

highlight_code($code)

[PaulRyan]

I left this is in to see if you could work it out for yourself, it seems not.

You need to try things for yourself, see if you can figure out the issue, anyhow...

 

       echo "<div id='codeBox'>{$code}</div>";

Change to:

       echo "<div id='codeBox'> ".highlight_string($result['code'])." </div>";

 

Regards, PaulRyan.

[ecabrera]

[ecabrera]

i have a question why didnt it work just by saying

<?php
if ($code)
{
echo "<div id='codeBox'>$code<>";
}
?>
