[SOLVED] Regex issues

[xyn]

First off, I would like to apologise for posting this, in the "incorrect" area, as i couldn't find the specific regex board.

 

Secondly, I've been working on my own basic template engine, every thing has been working fine, up until i used multiple

IF STATEMENTS within my html template page:

 

The Template file:

[code=php:0]<table width="600" cellspacing="0" cellpadding="0">
<tbody>
	{0|if:rows=0}
	<!-- No items in basket -->
	<tr class="formbg">
		<td colspan="2" width="600" height="25" class="head2" style="padding-left:5px;">
		There are not any products in your shopping basket!
		</td>
	</tr>
	{0|else}
	{while}
	{1|if:row=1}
	<!-- The headings for the basket table -->
	<tr class="formbg">
		<td width="300" height="25" class="head3" style="padding-left:5px;">
		Heading
		</td>
		<td width="300" height="25" class="head3">
		Title
		</td>
	</tr>
	{1|endif}
	<!-- The basket items -->
	<tr class="formbg">
		<td width="300" height="25" class="head3" style="padding-left:5px;">
		-
		</td>
		<td width="300" height="25" class="head3">
		-
		</td>
	</tr>
	{endwhile}
	{0|endif}
</tbody>
</table>

[/code]

 

 

Basically I can collect the table row between {0|if:rows=0} and {0|else}.

I can also collect everything from {while} to {endwhile} between {0|else} and {0|endif}.

 

However, when i try to extract the following as separate items, the regular expressions will not work...

 

[code=php:0]{1|if:row=1}
<!-- The headings for the basket table -->
<tr class="formbg">
<td width="300" height="25" class="head3" style="padding-left:5px;">
Heading
</td>
<td width="300" height="25" class="head3">
Title
</td>
</tr>
{1|endif}

[/code]

 

 

My php code:

 

[code=php:0]function basket_checkout(){
	# define smart tags
	$smart_tags=array(
		array()
	);
	# select products in basket
	$cart=mysql_query("select * from `sc_cart_basket` where `sc_basket_user`='{$_SESSION[$this->c_session]}' order by `sc_basket_added` asc");
	$cart_html=file_get_contents("$this->c_root/basket_checkout.inc.php");
	# regular expressions
	$pattern_elseif_1="/^(.*?)\{(0\|if:rows=0)\}(.*?)\{(0\|else)\}(.*?)\{(0\|endif)\}(.*?)$/us";

	$pattern_while="/^(.*?)\{(while)\}\{(1\|if:row=1)\}(.*?)\{(1\|endif)\}(.*?)\{(endwhile)\}(.*?)$/us";



	$html_table_start=preg_replace($pattern_elseif_1, "\\1", $cart_html); # start table
	$html_no_rows=preg_replace($pattern_elseif_1, "\\3", $cart_html); # if no mysql rows, insert 1 table row

	$html_basket_while=preg_replace($pattern_elseif_1, "\\5", $cart_html);  # the while loop

	$html_basket_itmes=preg_replace($pattern_while, "\\4", $html_basket_while);  # DEBUG 1





	$html_table_end=preg_replace($pattern_elseif_1, "\\7", $cart_html); # end the table (debug only)



	echo $html_table_start, $html_basket_itmes, $html_table_end;
	// -->
}

[/code]

I fixed it.. the regex i now use is...

 

"/^(.*?)\{(while)\}(.*?)\{(1\|if:row=1)\}(.*?)\{(1\|endif)\}(.*?)\{(endwhile)\}(.*?)$/us";
