QUACK Posted March 21, 2006 Share Posted March 21, 2006 I created a template class in Python worked perfect. I decided to convert it to PHP.It works as expected execpt one thing. When I do a loop and assign the block it counts backwards. Ill explaine ...[code]<?php########################################################## FILENAME: template.php# COPYRIGHT: (C) 2006, Kyle King (aibotca@yahoo.ca )################################################################################################## Class: Template# 1: set_file.# 2: assign_vars.# 3: assign_block.# 4: delete_block.# 5: parse.########################################class Template{ var $new_tpl; ######################################## # Function: set_file # 1: template, string. ######################################## function set_file ( $template ) { # Set new_tpl to the contents of $template $this->new_tpl = file_get_contents ( $template ); } ######################################## # Function: assign_vars # 1: array, array. ######################################## function assign_vars ( $array ) { # Loop though the array. foreach ( $array AS $key => $value ) { # Replace the key with the value in new_tpl. $this->new_tpl = str_replace ( '{' . $key .

See assign_block in the PHP code thats what does the block :(Thanks Quote Link to comment Share on other sites More sharing options...
.-INSANE-. Posted March 21, 2006 Share Posted March 21, 2006 ok im not very good in PHP so this may not help but i dont think u set a value it looks empty to me but like i said im not good so dont flame me for this Quote Link to comment Share on other sites More sharing options...
wickning1 Posted March 21, 2006 Share Posted March 21, 2006 I'll try and illustrate what's happening.<!-- BEGIN example_block -->{example_block.S_LOOPTEST}<br /><!-- END example_block -->you run assign_block and it does this:<!-- BEGIN example_block -->{example_block.S_LOOPTEST}<br /><!-- END example_block -->Value: 0<br />Run it again and you get:<!-- BEGIN example_block -->{example_block.S_LOOPTEST}<br /><!-- END example_block -->Value: 1<br />Value: 0<br />Run it again and you get:<!-- BEGIN example_block -->{example_block.S_LOOPTEST}<br /><!-- END example_block -->Value: 2<br />Value: 1<br />Value: 0<br />Run delete_block and you get:Value: 2<br />Value: 1<br />Value: 0<br />Now I don't know exactly what you're shooting for but you could fix it by printing the values above the block:[code] function assign_block ( $block_name, $array ) ... # Replace keys with old keys + block in new_tpl. $this->new_tpl = str_replace ( $match[ 0 ], $block . $match[ 0 ], $this->new_tpl ); }[/code] Quote Link to comment Share on other sites More sharing options...
QUACK Posted March 21, 2006 Author Share Posted March 21, 2006 ah $block . $match[ 0 ] worked >.< all i had to do was switch it haha thanks very muchit does:Value: 0Value: 1Value: 2:) and ur statement was correct, it leave the block there and adds more too it until it deleted, simpel and works.
