Question about something in template.php

[Pests]

Not too sure if this would be the place to post this, but I guess it is related to the styling...

Was looking over the source of template.php and found this, can someone tell me what it does? I think I have a pretty good idea, but it might be wrong due to my lack of knowledge of $_tpldata array.

Code: Select all

if (strstr($blockname, '.'))
      {
         // Nested block.
         $blocks = explode('.', $blockname);
         $blockcount = sizeof($blocks) - 1;

         $str = &$this->_tpldata;
         for ($i = 0; $i < $blockcount; $i++)
         {
            $str = &$str[$blocks[$i]];
            $str = &$str[sizeof($str) - 1];
         }

         // Now we add the block that we're actually assigning to.
         // We're adding a new iteration to this block with the given
         // variable assignments.
         $str[$blocks[$blockcount]][] = $vararray;
      }

This code assigns variables to block if block is nested.

> if (strstr($blockname, '.'))

Checks if there is dot in block name

> $blocks = explode('.', $blockname);

Splits it to array of block names

> $blockcount = sizeof($blocks) - 1;

get number of blocks

> $str = &$this->_tpldata;

variable $str points to $this->_tpldata

> $str = &$str[$blocks[$i]];

$str points to block array

> $str = &$str[sizeof($str) - 1];

$str points to last item in array.

by this time if variable name was block1.block2.block3 then $str points to last item in block2

> $str[$blocks[$blockcount]][] = $vararray;

adds one more item to block array.

I hope this explanation is clear enough.

Yeah, its good. Anyone mind explaining to me a bit more of the layout of $_tpldata?

[Acyd Burn]

print_r($_tpldata);

[Pests]

Thats going to help, considering Im not using the file anywhere.

Just using print_r() prints everything on one line (which on my opinion is hard to read)!
Try this:

Code: Select all

<?php
print(nl2br(print_r($_tpldata, true)));
// Unset it
unset($tpldata_info);
?>

If the parentheses are confusing:

Code: Select all

<?php
$tpldata_info = print_r($_tpldata, true);
$tpldata_info = nl2br($tpldata_info);
print($tpldata_info);
// Unset it, just in case something else uses that var
unset($tpldata_info);
?>

And if you want nothing but the print_r(), do this:

Code: Select all

<?php
$tpldata_info = print_r($_tpldata, true);
$tpldata_info = nl2br($tpldata_info);
print($tpldata_info);
// No unsetting here, as we're exiting anyway
exit();
?>

or you could use

Code: Select all

<?php
echo '<pre>';
print_r($_tpldata);
echo '</pre>';
?>

Or

Code: Select all

header('Content-Type: text/plain');
die( print_r($_tpldata, 1) );

Incorrect. It prints it out with newlines, but not HTML br tags.

Incorrect. It prints it out with newlines, but not HTML br tags.

Which means "everything on one line" when you're viewing the final page (not the source).
