 Posted: Mon Oct 06, 2003 12:11 pm Post subject: Hacked function.assign.php to allow array appends |
 |
|
I wanted to assign a value to an array from within a template and realized that it wasn't possible (or me to stupid to understand how I was supposed to do so  )
However, I hacked it into the standard-plugin "assign". Maybe somebody else can use it too or it might even make it into the smarty-code.
It's a quick hack and I have not yet tested it intensely so maybe there might come an update soon.
To append a value to an array you write e.g.:
| Code: | | {assign var="previews.number" value="20"} |
Which works similar to the nativ PHP code:
[php:1:e00571d5b7]<?php
$previews['number'] = '20';
?>[/php:1:e00571d5b7]
I choose the . as delimiter because you can't use it anyways in a variable name within smarty and because it reflects the usage of smarty to call an index of an array.
And here the code:
[php:1:e00571d5b7]<?php
function smarty_function_assign($params, &$smarty)
{
extract($params);
if (empty($var)) {
$smarty->trigger_error("assign: missing 'var' parameter");
return;
}
if (!in_array('value', array_keys($params))) {
$smarty->trigger_error("assign: missing 'value' parameter");
return;
}
//expand . to array structures
if (strpos($var,'.') !== false) {
$parts = split("\.",$var);
$varname = array_shift($parts);
$lastpart = array_pop($parts);
$array = array();
$previous = &$array;
foreach ($parts as $part) {
$previous[$part] = array();
$previous = &$previous[$part];
}
$previous[$lastpart] = $value;
$smarty->append($varname, $array, true);
} else {
$smarty->assign($var, $value);
}
}
?>[/php:1:e00571d5b7]
Hope it helps somebody |

*mumble*
No, I don't like it. Not that I wouldn't like/appreciate his work but I hate to do work that's already been done - but well, my fault  |
