| {section} doesn't work with simplexml. use {foreach}. |

it seems messju is right.
section is not workable with simplexml.
returned value from simplexml is mixing of array and object.
it's too much confusing.
i'll try foreach but foreach has few features to use.
thanks

there is hardly anything you can do with {section} that you can't do also with {foreach}. |

for your convenience, i'll post print_r dump of $xml
| Code: |
SimpleXMLElement Object
(
[movie] => SimpleXMLElement Object
(
[title] => PHP: Behind the Parser
[characters] => SimpleXMLElement Object
(
[character] => Array
(
[0] => SimpleXMLElement Object
(
[name] => Ms. Coder
[actor] => Onlivia Actora
)
[1] => SimpleXMLElement Object
(
[name] => Mr. Coder
[actor] => El Actor
)
)
)
[plot] =>
a documentary.
[rating] => Array
(
[0] => 7
[1] => 5
)
)
)

Here is my solution for simplexml in php 5.
i tried with for but not worked, instead use foreach.
test.php | Code: |
<?php
$smarty =& new Smarty;
include 'example.xml';
$xml = simplexml_load_string($xmlstr);
$tables = array();
foreach($xml->table as $t) { // don't use 'for'
$table = $t;
$fields = array();
foreach($table->field as $f) {
$fields[] = $f;
}
$type = (string)$table['type'];
$tables[$type] = $fields;
}
$smarty->assign('tables', $tables);
$smarty->display('test.tpl');
?>
|
example.xml | Code: |
<?php
$xmlstr = <<<XML
<?xml version='1.0' standalone='yes'?>
<data>
<table type="page">
<field><Name>page</Name><Template>home.htm</Template></field>
<field><Name>category</Name><Template>category.htm</Template></field>
</table>
<table type="company">
<field><Name>CNN</Name><Type>news</Type></field>
<field><Name>GM</Name><Type>car</Type></field>
</table>
</data>
XML;
?> |
test.tpl | Code: |
<!--[assign var=fields value=$tables.page]-->
<!--[section name=x loop=$fields]-->
id: <!--[$smarty.section.x.index+1]-->
Name: <!--[$fields[x]->Name]-->
Template: <!--[$fields[x]->Template]-->
<!--[/section]-->
<!--[assign var=fields value=$tables.company]-->
<!--[section name=x loop=$fields]-->
id: <!--[$smarty.section.x.index+1]-->
Name: <!--[$fields[x]->Name]-->
Type: <!--[$fields[x]->Type]-->
<!--[/section]--> |
test result
| Code: | id: 1
Name: page
Template: home.htm
id: 2
Name: category
Template: category.htm
id: 1
Name: CNN
Type: news
id: 2
Name: GM
Type: car

| Can we have smarty updated to work with the simplexml variables returned? Maybe we could pass it something saying its a simplexml variable, or it could parse them each time by checking what it is. THat might be slow though. |

again:
- smarty works fine with simplexml
- {section} doesn't
- {foreach} does
- there is nothing (in this context) that can't be done with {foreach}
conclusion:
- there is no need to "enhance" smarty in that direction |

why?
section is merely a for()-loop. you normally don't use a for()-loop to iterate over children of a simpleXML-node in php-land, either.
you should use foreach() in php and you should use {foreach} in the template. |

Just because it would make smarty complete. Why well tell people that some functions can't be used with all types of data returned, but others can?
Also, I think section is a lot easier to use in some situations. |

I don't think it would make Smarty more complete nor do I think that it has something to do with what variable types functions can take -- there are many examples of needing to use specific types or structures in Smarty functions and this is no exception. In fact, even a normal associative array cannot be iterated with a section. Besides, section is typically harder to use than foreach and here it is actually impossible. If anything, section should be deprecated. |

About 80% of my clients use section. And in 3 PHP books I use, they prefer section.
So I doubt you should get rid of it. |
