What way could I do this

I was just wondering I have all of these arrays such as $user[name]; Now what my problem is I have a repeating loop that gets a few templates that I store in the database. Don't ask why I just want them their for what I'm trying to learn. My problem is whenever I loop and echo, some of those templates will call upon stuff like $user[name] and it should output a text of like Joe for example... instead it only ouputs the actual text of $user[name].

Hopefully I'm not confusing anyone, but is there a way that if you define something in a file and then run a query if the query has any information on the echo statement of whats stored inside such as an array or variable that on the output it would display what it has been defined too?

You muste evaluate templates to get the variables in:

PHP Code:


		
			
eval('$template = "' . fetch_template('templatenamer') . '";');

Look at the code at the top of every vB file, see a pattern? Especially this...

PHP Code:


		
			
require_once('./global.php');

$bbuserinfo comes from there and is an array with all of the current user's vb info if I understand correctly. I do not have a list of what's in there. There may be one at vb.com.

yeah, and what he said too.

So lets say I had something like this...

PHP Code:


		
			
$result = mysql_query('SELECT * FROM templates'); 

while ($row = mysql_fetch_assoc($result)) 

{ 

    $templates[$row['name']] = $row['template'];     

} 



echo $templates['header']; 

echo $templates['index'];

How would I complete the transformation? Btw noppid this isn't for a vb, I'm just trying to learn PHP by creating a complex news program

PHP Code:


		
			
$compiled_header_template = str_replace('\\\\$', '\\$', addslashes($templates['header']));

eval('$header = "' . $compiled_header_template . '";');

echo $header;

There's a few problems that arise when I do that... It now retrieves the data but at the same time when it does, it now won't let me do like set widths for tables or to be able to call upon any CSS such as the class = to whatever and so forth... Any ways around that one?

Hmm ...

PHP Code:


		
			
<?php

 $foobar = 'Foo Bar';

 $templates['header'] = '<table width="100%" class="mytable"><tr><td>$foobar</td></tr></table>';

 $compiled_header_template = str_replace('\\\\$', '\\$', addslashes($templates['header']));

 eval('$header = "' . $compiled_header_template . '";');

 echo $header; 

?>

Output

HTML Code:

<table width="100%" class="mytable"><tr><td>Foo Bar</td></tr></table>

Seems to work for me.

I've triple checked this and something is definately wrong with this... This is my entire php code for anything retaining towards the templates.

PHP Code:


		
			
$result = mysql_query('SELECT * FROM templates'); 

while ($row = mysql_fetch_assoc($result)) 

{ 

    $templates[$row['name']] = $row['template'];     

} 





// echo $templates['header']; 





$compiled_header_template = str_replace('\\\\$', '\\$', addslashes($templates['header'])); 

eval('$header = "' . $compiled_header_template . '";'); 

echo $header;

If I just echo the $header template without doing any of the str_replace functions and so forth.... The css will work, the set table widths, and so forth will work, BUT any variables or arrays that I output wont. I can use your way and get most of the variables and arrays to ouput but then it will not accept the CSS properly nor the set table widths, heights, and so forth. Any idea on what could possibly be the problem?

The code seems to be OK.
Can you post a template that does not work?

PHP Code:


		
			
<body bgcolor='#ffffff' leftmargin='0' topmargin='0' bottommargin='0' rightmargin='0'>

<table cellpadding='0' cellspacing='0' border='0' class='maintable' width='650' align='center'>

<tr>

<td>LOGO GOES HERE</td>

</tr>

<tr>

<td background='images/navbg.jpg' height='20'>LINKS</td>

</tr>

<tr>

<td>

This is the header template that doesnt even call upon any arrays. I have it after all the php code at the bottom of the page right before the last } ?> and even this one will not cooperate
