RE: help : looping for template

I found another mistake, but you could have found it on your own imho. Did you take a serious effort to find the error?

You want to replace the KEY with the VALUE, so the tag will look like {blockName.key} and not like {blockName.value}.

php Code:

Original - php Code
foreach ($data as $key => $value) { $blockCode = str_replace ("{".$blockname.".".$key."}", $value, $blockCode); }

foreach ($data as $key => $value) {
        $blockCode = str_replace ("{".$blockname.".".$key."}", $value, $blockCode);
    }

Next time, try a little harder yourself to find the error. That will improve your php knowledge, your knowledge about this template system and it will save you a lot of time

RE: help : looping for template

First off This piece of code was having problems.

php Code:

Original - php Code
function assign_block_vars($blockname, $data) { $blockCode = $this->get_block($blockname); foreach ($data as $key => $value) { $blockCode = str_replace ("{".$blockname.".".$key."}", $value, $blockCode); } $this->page = str_replace ($this->return[0], $blockCode.$this->return[0], $this->page); }

 
function assign_block_vars($blockname, $data)
{
    $blockCode = $this->get_block($blockname);
    foreach ($data as $key => $value) {
        $blockCode = str_replace ("{".$blockname.".".$key."}", $value, $blockCode);
    }
    $this->page = str_replace ($this->return[0], $blockCode.$this->return[0], $this->page);
}

keeps giving me this error:

php Code:

Original - php Code
Undefined offset: 0

 
Undefined offset: 0

on the lines where $this->return[0] is located. On BOTH the assign_block_vars and get_block functions

all have to do with the return (i think...)

This is my class

php Code:

Original - php Code

class Page { 
     var $page;

// --------------

                         $this->page = implode("", file($template));

}

  }
}

i use this code to do the replacing.

php Code:

Original - php Code
$index->assign_block_vars("Announcements",array("Content_Body" => $row['body'], "Content_Header"=> $row['subject'], "UserName" => $row['username']));

 
$index->assign_block_vars("Announcements",array("Content_Body"  => $row['body'],
                        "Content_Header"=> $row['subject'],
                        "UserName"  => $row['username']));

and in the template its something like this

php Code:

Original - php Code
<!-- START Announcements --> Title:{Announcements.Content_Header} By:{Announcements.UserName} <hr> {Announcements.Content_Body} <!-- END Announcements -->

 
<!-- START Announcements -->
Title:{Announcements.Content_Header} By:{Announcements.UserName}
<hr>
{Announcements.Content_Body}
<!-- END Announcements -->

Also im developing on windows. And I also test this on my site which is a linux host.
Both gave me errors when using

php Code:

Original - php Code
$blockCode = $this->get_block($blockname);

 
$blockCode = $this->get_block($blockname);

and

php Code:

Original - php Code
$this->page = str_replace ($this->return[0], $blockCode.$this->return[0], $this->page);

 
$this->page = str_replace ($this->return[0], $blockCode.$this->return[0], $this->page);

like the above function at start/top of this post
