What that line does is that it searches for all occurrences of {([a-z0-9\.]+)} within the template file (which contents are in $contents) and then parses the matched string to $this->replace_callback.
Then the replace_callback method gets a string eg. "user.posts.count". It then "explodes" that string by each occurrence of "." so we get an array which looks something like this:
PHP Code:
Array
(
[0] => user
[1] => posts
[2] => count
)
And then it selects the correct data from the array(the second argument of the parse method) and returns it to the preg_replace_callback method, which in turn replaces the matched string by the returned data in the $contents string.
I recommend that you read the php site.. |
Thanks!
One thing that I noticed though.
Cause in my database, I have a table called posts, and wihin it, every row starts with "post_", for example:
Code:
post_content
post_author
post_time
And when I use like this in the template file:
HTML Code:
Posted at {post.post_time}
..it didn't work
PHP Code:
foreach($posts as $post) {
$tanaxia['template']->parse(
array(
'post' => $post
)
));
}
$post will contain an array with all the data from the fetched rows.. so that should work :S
But it doesn't.
It works if I do like this:
PHP Code:
foreach($posts as $post) {
$tanaxia['template']->parse(
array(
'post' => array(
'posttime' => $post['post_time'],
'postauthor' => $post['post_author'],
'postcontent' => $post['post_content']
)
));
}
HTML Code:
<center>
<table width="900" border="1">
<tr>
<td colspan="3"><font size="2">Posted {post.posttime}</font></td>
</tr>
<tr>
<td colspan="2" width="30%">By: {post.postauthor}</td>
<td>{post.postcontent}</td>
</tr>
</table>
</center>
Notice that I removed the _ from the template...
Any idea how to fix that ??
