| I spent some time reconstructing your code and figuring out what was needed to solve the problem. I changed your get_statment funtion to return an array of tags not just a single tag. Also I made a few changes to parse_if
This is what I came up with. Give it a try: PHP Code: <?php
class template
{
var $base_path;
var $reset_vars;
var $ldelim = '<';
var $rdelim = ' />';
var $BAldelim = '<';
var $BArdelim = '>';
var $EAldelim = '</';
var $EArdelim = '>';
var $scalars = array();
var $arrays = array();
var $carrays = array();
var $ifs = array();
function template($base_path = NULL, $reset_vars = TRUE) {
if ($base_path) {
$this->base_path = $base_path;
}
$this->reset_vars = $reset_vars;
}
function set($tag, $var, $if = NULL) {
if (is_array($var)) {
$this->arrays[$tag] = $var;
if ($if) {
$result = $var ? TRUE : FALSE;
$this->ifs[] = $tag;
$this->scalars[$tag] = $result;
}
} else {
$this->scalars[$tag] = $var;
if ($if) {
$this->ifs[] = $tag;
}
}
}
function set_cloop($tag, $array, $cases) {
$this->carrays[$tag] = array(
'array' => $array,
'cases' => $cases);
}
function reset_vars($scalars, $arrays, $carrays, $ifs) {
if ($scalars==true) { $this->scalars = array(); }
if ($arrays==true) { $this->arrays = array(); }
if ($carrays==true) { $this->carrays = array(); }
if ($ifs==true) { $this->ifs = array(); }
}
function get_tags($tag, $directive) {
$tags['b'] = $this->BAldelim . $directive . $tag . $this->BArdelim;
$tags['e'] = $this->EAldelim . $directive . $tag . $this->EArdelim;
return $tags;
}
function get_tag($tag) {
return $this->ldelim . 'tag:' . $tag . $this->rdelim;
}
function get_statement($t, &$contents) {
$tag_length = strlen($t['b']);
$tags = array();
$fpos = strpos($contents, $t['b']) + $tag_length;
while ($fpos) {
$lpos = strpos($contents, $t['e'], $fpos);
$length = $lpos - $fpos;
$tags[] = substr($contents, $fpos, $length);
$fpos = strpos($contents, $t['b'], $lpos);
