[PHPTAL] variable variables in phptal?
Is it possible to use variable variables in PHPTal ?
eg I have a PHP array
$phptal-fieldnames = array(array('key'='first_name',
'description'='First Name'), array('key'='address',
'description='Address');
and an object
$person= new stdClass();
$person-first_name = 'Joe';
$person-address='His_street 1';
$phptal-person = $person;
and in my template I'd like to use the key of fieldnames in a repeat
...
div tal:repeat=field fieldnames
${field/description}: ${person/${field/key}}
/div
This doesn't work - but is there an other way to achieve it ?

[PHPTAL] nested UL
I have a multilevel array, where, as the template concerns, the number
of levels is unlimited.
eg
$objects = array('Food'=array('Fruit'=array('Red'=array('Cherry',
'Strawberry'), 'Yellow'=array('Banana')), 'Meat'=array('Steak',
'Hamburger'));
I'd like to loop through this array in my templates and end up with
ul
liFood
ulliFruit
ulliRed
ulliCherre/liliStrawberry/li/ul
/liliYellow
... etc
How could I do this, without needing to know the number of levels?

Re: [PHPTAL] runtime generated slot names
I'm always interested in learning, so could you please enlighten me... why would you want to have changing names for a fixed slot? It's like having a certain function that can have different names. Most of the time, it works the other way around (a fixed name with a different functionality). GRolf Monday, November 8, 2010, 12:53:55 PM, you wrote: Hi all, I'd like to create a macro with fillable slots but I'd like the names of these slots to be based on variable information passed to the macro. It appears at the moment that the content of a 'define-slot=' is not processed like other content and is simply treated as a string. I'd prefer not to resort to macros because all the slots themselves are fully static - I just want to control which of these static slots are inserted at any time. I recognise that one possible suggested solution here might be a collection of conditionals to pick the slot but the macro I'm writing is in a library and the slot names are, therefore, not definable in advance. I hope this makes sense! In essence, my fill-slot statements are statically named but my define-slot statements need to be able to take variable string content. Anyone have any ideas?

[PHPTAL] implode()
I often find myself using tal:repeat to implode an array
in php
$myarr = array('one', 'two', 'three');
is easily converted to
one, two, three
with
implode(', ',$myarr);
But in PHPTal, this is quite cumbersome
span tal:repeat=val myarr
${val}span tal:condition=not:repeat/val/end, /span
/span
Isn't there an easier solution?

Re: [PHPTAL] callback?
and how can I solve this if I want to use it in my tal:repeat?
e.g. for a Client, who has (potentially) multiple invoices
tr tal:repeat=client clients
td${client/name}/td
tdspan tal:repeat=invoice client/invoices${invoice}tal:block
tal:condition=not:repeat/invoice/end,/tal:block/span/td
/tr
this works fine if I retrieve all invoices before, but can I do it without
looping through all clients in PHP first, if I'd have a function
getInvoices($client_id)... ?

PHPTAL automatically calls methods in TAL expressions. If you use ORM it
should be quite simple, e.g. if you have Employee object that has
getDepartment() method that returns Department object:
li tal:repeat=employee employees
tal:content=employee/getDepartment/name/
Alternatively you can call PHP functions using php: prefix in expressions:
li tal:repeat=employee_row employees_array
tal:block tal:define=department
php:get_department_row(employee_row['department_id'])
tal:content=department/name/

[PHPTAL] auto-select checkboxes
I have the feeling that this should be possible, and maybe trivial,
but I don't know how to solve it.
I have an object ($person), who lives in a state ($person-state).
I also have a list of states ($states). Both are assigned to phptal.
$phptal-person = $person;
$phptal-states = $states;
In my PHPTAl template I have
select name=state
option tal:repeat=state states value=${state}${state}/option
/select
I'd like PHPtal to put the state of $person to selected. I know how to
achieve it when I loop through the states array in PHP first, add an
active flag to the one state that is active and use tal:attributes
then, but would it be possible to achieve it without looping through
all states in php?
something like ...
option tal:repeat=state states tal:attributes=selected person/state eq
state value=${state}${state}/option

Re[2]: [PHPTAL] ajax and phptal
Since I was struggling with this too, I'm very interested in your
view.
I use a different approach:
since a PHP-driven website usually consists of many .php scripts, I
like to keep my templates organised in a
1-template-for-each-php-script (eg. index.php uses index.tpl,
subscribe.php uses subscribe.tpl). Otherwise you're more busy with
opening and closing templates to make changes (and trying to remember
which file you need) than making the changes.
I have 1 file (general.tpl) that holds the general page structure of
every page, and then the 1-template-per-script as described above.
my general.tpl has something like (more complex than the example below
of course)
html metal:define-macro=globalpage
body
div id=header tal:define-slot=header/div
div id=content tal:define-slot=content/div
div id=footer tal:define-slot=footer/div
/body
/html
Every script then calls it's own template file (eg index.tpl)
with
tal:block metal:use-macro=general.tpl/globalpage
tal:block metal:fill-slot=content
Content of page goes here...
/tal:block
/tal:block
If I have a page that needs to show different pages (eg: form +
feedback after submission + error if required), eg register.tpl
tal:block metal:use-macro=general.tpl/globalpage
tal:block metal:fill-slot=content tal:condition=php:
template=='form'
form method=post
username: input type=text name=username/
Pwd: input type=password name=pwd/
input type=submit name=submit value=Register/
/form
/tal:block
tal:block metal:fill-slot=content tal:condition=php:
template=='succeed'
your registration was successfull
/tal:block
tal:block metal:fill-slot=content tal:condition=php:
template=='failed'
your registration was not successfull. please try again.
/tal:block
/tal:block
register.php would then set $phptal-template = 'succeed' etc to show
the correct template...
In these circumstances, using AJAX to retrieve only part of the page
is harder. Do you have any feedback on that? For maintenance and
support, I really really like to keep my templates grouped with the
script. I know I could create a register_form.tpl,
register_succeed.tpl, register_failed.tpl etc but this quickly
becomes a cumbersome operation to open/close all those docs, let alone
if you have a PHP script that runs through multiple, consequetive
forms.

Hi
I am working on ajax php website. Ajax makes using phptal more
complicated.
My approach is to divide single page to several php files and every
time at single page i create new object of $tpl. It means that I
have to use several $tpl-execute() at the first page load. I think
it is not optimal.
My question is whether there is most efective way to use phptal and
ajax?
page.xhtml:
body
stuff
tal:block metal:use-macro=widget.xhtml/show_widget /
stuff
/body
widget.xhtml:
div metal:define-macro=show_widget
ajax me!
/div
tal:block metal:use-macro=show_widget /
This will let you either execute page.xhtml with all stuff in it, or
execute widget.xhtml and just output that single fragment. You can use
variables in use-macro (e.g. show_${name}), so you're not limited to
one thing per file.

[PHPTAL] access previous / next item in array?
I'm doing a
div tal:repeat=item items
Previous id: ???
Current id: ${item/id}
Next id: ???
/div
Is there any way to add a callback function that will be called on
each repeat, so I could easily put the next and previous id ?
I could loop through the array in PHP, before assigning to PHPTal
object, and set them. But that would mean looping through the array
twice (once before, once for output)...

Re: [PHPTAL] PHPTAL prefilters
It sounds interesting and an improvement from previous versions. However, I'd like to see some tutorials putting this to work. When do you use those things, how can they be applied to improve your templates and/or code etc...

But have a look at the source of PHPTAL/PreFilter.php: http://phptal.org/files/PHPTAL-1.2.1b3.tar.gz There's base abstract class for prefilters. Previously you had to implement interface, now you'll have to extend the class. This change allows me to add new ways of filtering in the future without any breaking changes in the interface. The class has methods like filterDOM($node), filter($source) — you just override which ones you want. You can override all of them at once if you need, all will be called. DOM version lets you edit PHPTAL DOM nodes after they've been parsed and edit exactly what PHPTAL sees. There's also filterDOMFragment($node) method. I plan to add phptal:filter=name_of_the_filter attribute, which will let you apply filters selectively, e.g. (this is not implemented yet) ul phptal:filter=remove_whitespace liIE hates newlines in lists/li /ul script phptal:filter=minify_javascript etc. /script I've replaced PHPTAL-setPreFilter($filter) with PHPTAL-addPreFilter ($filter, $name = null). Yes, this means you can have any number of filters without workarounds (finally! :) I wonder if there should be separate method for adding named prefilters for use with phptal:filter only? (e.g. you might want to make JS minification prefilter available, but you don't want to minify entire file).

Apparently you're using text/html mode. Do you use HTML 5 output mode or
XHTML?
XHTML requires to be escaped as lt; (otherwise it would be ill-formed
start of a tag).
HTML requires the opposite - it has hardcoded rule that script content
is CDATA where entities aren't interpreted.
Any way to enforce phptal to put the content from the tal:block to
be passed as text ?
Strictly speaking it is passed as text, and text in markup has to be
escaped.
Try wrapping script in fill-slot in /*![CDATA[*/ … /*]]*/. That is a
workaround for XHTML served as HTML.

Am I taking the wrong approach, or is there a solution?
I also like using the solution that Levi suggests.
Just note that the element's default content will be used if it is
defined - this has the added value of being able to view your
template (e.g) in your browser, without any replaced variables.
So, note that this will output nothing if pagetitle is not assigned:
title tal:content=pagetitle|default/title
However, this will output Some Page Title if pagetitle is not assigned:
title tal:content=pagetitle|defaultSome Page Title/title
