[PHPTAL] Array Syntax Question

I think I see your dilemma. But, the way you put it is kind confusing.
So let me take your first array and try to explain something about how
PHPTAL works on them.
Lets take:
$fooArr = array('bazKey' => array('item1', 'item2', 'item3'));
Let me give you some code:
<?php
include_once('PHPTAL.php');
$fooArr = array('bazKey' => array('item1', 'item2', 'item3'));
$template = new PHPTAL('test2.xhtml');
$template->set('array', $fooArr);
try {
print $template->execute();
} catch(Exception $e) {
print "Error: ".$e->getMessage();
}
?>
This is the xHtml file I am using for this example:
<html>
<head>
</head>
<body>
<div tal:repeat="item array">
<div tal:repeat="nested_item item" tal:content="nested_item"/>
</div>
</body>
</html>
Okay with that done lets break up how I was able to get to the
information of the multi-dimensional array.
<div tal:repeat="item array">
This statement allows me to get access to the value of the value pairs,
which is held by BazKey. I guess here I could probably say, keys are
pretty much useless when your array is set up like this, however, there
are ways to make it make sense, which I will show you in another
example. But back to this example.
Now the final, nested array is access with this statement:
<div tal:repeat="nested_item item" tal:content="nested_item"/>
The output you will get is this:
<html>
<head>
</head>
<body>
<div>
<div>item1</div><div>item2</div><div>item3</div></div></body>
</html>
Now for a more complex example:
Here is the php code:
<?php
include_once('PHPTAL.php');
$array = array( array('position' => 'Management', 'personel' =>
array('Billy', 'Mandy')),
array('position' => 'Programmers', 'personel' =>
array('Kevin', 'Jimmy', 'Tucker'))
);
$template = new PHPTAL('test.xhtml');
$template->set('array', $array);
try {
print $template->execute();
} catch (Exception $e) {
print "Error: ".$e."\n";
}
?>
Here is the xhtml file:
<html>
<head>
</head>
<body>
<span id="table_css"tal:repeat="multi_array array">
<div id="title_css" tal:content="multi_array/position"/>
<div id="employee_css" tal:repeat="person
multi_array/personel" tal:content="person" />
</span>
</body>
</html>
The output of this script is this:
<html>
<head>
</head>
<body>
<span id="table_css">
<div id="title_css">Management</div>
<div id="employee_css">Billy</div><div
id="employee_css">Mandy</div> </span><span id="table_css">
<div id="title_css">Programmers</div>
<div id="employee_css">Kevin</div><div
id="employee_css">Jimmy</div><div id="employee_css">Tucker</div> </span>
</body>
</html>
I hope I have answered your question.
Best regards,
