Hello

In my wrork with smarty often happens that I need to create array of indexes in template

expample:

Code:
{callAction path="project/return_category"  assign=category }
{foreach from=$category name=y item=cat}
    {callAction path="project/return_subcategory" centrum=$cat.id assign=subcategory}
    {foreach from=$subcategory name=z item=sub}
        {assign var=val[] value=$sub.id}
    {/foreach}
{/foreach}

Pass to some selectbox handler or somthing :)

{select name="name" namespace="0" output=$val values=$val selected=$arrow.input.sub }



I can't do this directly from template now :/ . Sometimes it's very tiring. I bet that it is not only my problem.

Proposition:

Change assign compiler function to:

[php:1:429206523a]<?php
function smarty_compiler_assign($tag_attrs, &$compiler)
{
$_params = $compiler->_parse_attrs($tag_attrs);

if (!isset($_params['var'])) {
$compiler->_syntax_error("assign: missing 'var' parameter", E_USER_WARNING);
return;
}

if (!isset($_params['value'])) {
$compiler->_syntax_error("assign: missing 'value' parameter", E_USER_WARNING);
return;
}

//matches "foo[]"
if( substr( $_params['var'] ,-3, -1 ) == "[]" ){

$varName = substr( $_params['var'] , 1, -3 );

return "
\$compilerAssignVarValue = \$this->get_template_vars( \"$varName\" );

if( !\$compilerAssignVarValue ){
\$compilerAssignVarValue = array();
}

if( !is_array( \$compilerAssignVarValue ) ){
\$this->trigger_error(\"assign: variable '$varName' isn't array\", E_USER_WARNING);
}

\$this->assign( \"$varName\", array_merge( \$compilerAssignVarValue, array ( {$_params['value']} ) ) );";


}else{

return "\$this->assign({$_params['var']}, {$_params['value']});";

}



}
?>[/php:1:429206523a]

What are you think about this?
