im stuck help please

[homer09001]

ok ive written a php CMS to my needs but problem number 1:
i want to embed php into my content but when i view it front end its not displaying whaty i want just pure php code:

this code is the code that gets the content from the database and displays it

<?php
include "config.php3";
include "dbconnect.php3";

$id = $_REQUEST['pageid']; 

if( isset($id) ) 
{ 
$a = "SELECT * FROM $table1 WHERE id='$id' AND published='1'";
$rows = mysql_query($a) or die (mysql_error());

while ($b = mysql_fetch_array($rows)){

$cont = $b['content'];
}

$test = mysql_num_rows($rows);


if($test == 1)
{
echo nl2br($cont);
}}
else
{
$rows = mysql_query("SELECT * FROM $table1 WHERE id = 000");

while ($b = mysql_fetch_array($rows)){

$welcome = $b['content'];
echo nl2br($welcome);
}}
?>

i was going to stick an if statement in to see if there is <?php and ?> in the content if so then parse it spereatly but i cant work out how.

any help would be greatly appreciated

You have line breaks in the right middle of your php. Here's what your source code looks like:

<td width='640' align='center' valign='top'>
<?php<br />
include "echo.php";<br />
?>
</td>

[homer09001]

of course it looks lie that your lookin at the page source code which is in HTML

[samudasu]

Uhmmm, ok genius. You go ahead and put <br />'s right in the middle of php code. Let us know how that's working out for ya!

i think he gets your point... but you are saying

nl2br > which converts all your linebreaks, to brs.

if you want to RUN the code contained in a string which you just pulled back from the database, you need to do an eval statement.

[samudasu]

Well, then Dude, you're admin panel is putting <br />'s in your code and that won't work! It probably turns newlines into <br /> automatically. Do you have another way to upload your scripts to your pages?
Now the question you should be asking is if you yourself get the point?

could you explain about this "Eval Statment"???

and sam i get what you mean and i tried entering the code like so:

<?php include "echo.php"; ?> 

and i have the problem of it not displaying now

http://uk.php.net/manual/en/function.eval.php

Example:

<?
$string = 'include("echo.php");';

eval("$string");
?>

[stevesweetland]

ok.

you have a string, mixed with html and php, right?

you cant just print it, and expect the server to know automatically that it has php code to run.

nl2br outputs a string, and every time it see's a linebreak, it prints a br.

eval outputs a string, and it expects it to be php code, so attempts to run it.

there are other factors to take into account when preparing a string for eval() use, primarily that you cannot pass anything but php to an eval statement. you cannot parse a html/php mixed string with eval alone.

probably what you need to do is strip out the php and run it seperately wherever it occurs.

you could do this using ereg, and whenever it finds php (identified by the php tags), do an eval on the statements.

www.php.net/eval will tell you all you need to know regarding running a string as code.

ok i think i got it sorted i replaced the follwoing code:

if($test == 1) 
{ 
echo nl2br($cont); 
}} 
else 
{ 

with:

if($test == 1)
{
eval ("?>$cont<?");
}}
else
{

nl2br is now used when teh content is created and inserted into the database meaning that i can now include php and html in teh one field and it runs perfectly

[homer09001]

for example in my basic content editor i enter this:

im testing the <?php echo "echo"; ?> code


testing the nl2br code aswell

and in the browser:

im testing the echo code

testing the nl2br code aswell

Thanks steve your a great help 😉

correct me if you think im wrong though please helps me learn the language 😃
