Getting numbers from string - without Internal Errors

[MCrosbie]

Hi,

 

Right, here is what I'm up to. In this CMS system all of the PHP code for the different variables e.g. {title} are stored in a MySQL database. The code searches for these variables in the pages contents, e.g. "<td>{title}</td>}", and replaces it with whatever the PHP code for that variable is e.g. $echo = $row['content']['title'], "<td>My Title</td>". In some of the pages, the variable is actually variable in it self, for instance for photo galleries, instead of creating a seperate variable for each gallery created, just use one. So for instance in a pages contents may be {PhotoGallery #100921}, this number needs to be named as $var['varivari'], before the PHP for variable is evaluated. I have already tried one solution using preg_match, which works fine, however on some pages where status=1, I get Internal Server Errors. Could you please help me to add in code to the "Current PHP code", to be able to enable this number to be picked up.

 

Database: DM_content

| 100921 |      1    |  100920  | Page 2 | Description    | page 2, page | {title}      |  Michael    | 100500        |

Page 1 - Live to the public (status = 0), Members only page (membersonly = 1), Is not shown on the menu (menu = 1)

Page 2 - Child page to Page 1, Under development (status = 1), Is shown in the menu (menu = 0)

 

Database: DM_variables

------------------------------------------------------------------------------------------------------------------

|    id      |                              code                        |                      php                            |

------------------------------------------------------------------------------------------------------------------

| 300221  |  /AO_photogallery #\b([1-9][0-9]{5})\b/      |      $echo = PhotoGallery ... etc          |

------------------------------------------------------------------------------------------------------------------

| 300222  |                          {title}                          |      $echo = $row['content']['title']        |

Current PHP code:

Code:

include('includes/startup.php');
$res['chlock'] = mysql_query("Select * from DM_site where variable='HS_status'");
$row['chlock'] = mysql_fetch_array($res['chlock']);
if($row['chlock']['value'] != 0 ){
include('includes/lockdown.php');
}else{
$res['contentselect'] = mysql_query("Select * from DM_content where level='1' and title LIKE '%home%'")or die("Error ". mysql_error()."");
$row['contentselect'] = mysql_fetch_array($res['contentselect']);
if(!$_GET['id']){$_GET['id'] = $row['contentselect']['id'];}
$res['content'] = mysql_query("Select * from DM_content where id='".$_GET['id']."'")or die("Error ". mysql_error()."");
$row['content'] = mysql_fetch_array($res['content']);
$res['template'] = mysql_query("Select * from DM_templates where id='".$row['content']['template']."'")or die("Error ". mysql_error()."");
$row['template'] = mysql_fetch_array($res['template']);
$content = $row['template']['template'];
$res['variables'] = mysql_query("Select * from DM_variables")or die("Error ". mysql_error()."");
while($row['variables'] = mysql_fetch_array($res['variables'])){
	$echo = '';
	eval($row['variables']['php']);
	$content = str_replace($row['variables']['code'], $echo, $content);
}
echo $content;
}

 

 

PHP code that gets the number, but sometimes gives Internal Server Errors for unknown reasons

Code:

include('includes/startup.php');
$res['chlock'] = mysql_query("Select * from DM_site where variable='HS_status'");
$row['chlock'] = mysql_fetch_array($res['chlock']);
if($row['chlock']['value'] != 0 ){
include('includes/lockdown.php');
}else{
$res['contentselect'] = mysql_query("Select * from DM_content where level='1' and title LIKE '%home%'")or die("Error ". mysql_error()."");
$row['contentselect'] = mysql_fetch_array($res['contentselect']);
if(!$_GET['id']){$_GET['id'] = $row['contentselect']['id'];}
$res['content'] = mysql_query("Select * from DM_content where id='".$_GET['id']."'")or die("Error ". mysql_error()."");
$row['content'] = mysql_fetch_array($res['content']);
$res['template'] = mysql_query("Select * from DM_templates where id='".$row['content']['template']."'")or die("Error ". mysql_error()."");
$row['template'] = mysql_fetch_array($res['template']);
$content = $row['template']['template'];
$res['variables'] = mysql_query("Select * from DM_variables ORDER by id ASC")or die("Error ". mysql_error()."");
while($row['variables'] = mysql_fetch_array($res['variables'])){
	$echo = '';
	if(preg_match($row['variables']['code'],$content,$matches)){
	 	$var['varivari'] = $matches[1];
		if($matches[1] = "[1-9][0-9]{5}"){
			$row['variables']['code'] = "{".$matches[0]."}";
		}
  			eval($row['variables']['php']);
		$content = str_replace($row['variables']['code'], $echo, $content);
	}
}
echo $content;
