Learning sympony2 and I have hit a wall and have tried numerous solution but nothing seems to work, I keep getting the
Unable to find template "ScoreBoardViewerBundle.Viewer.scoreboard_keeper.html.twig" in
ScoreBoardViewerBundle:Viewer:view.html.twig at line 15.
Here is my twig snipped:
{% if score_keeper=='sk' %}
{% include 'ScoreBoardViewerBundle.Viewer.scoreboard_keeper.html.twig' with {'score_keeper' : score_keeper} %}
{% else %}
{% include 'ScoreBoardViewerBundle.Viewer.scoreboard.html.twig' %}
{% endif %}
Initially I had only the file name, like I seen on examples from this twig site: Twig site but that produced the same error. The twig files are found in the same directory.
What am I doing wrong? Also I get the same issue regardless which file I try to include. I did have some typos but they should be fixed.
Here is the Controller I was using and it was able to open both views correctly, I just noted some twig in each file was redundant so hence the changes
public function viewAction($score_keeper)
{
//returns scoreboard view for score keeper
// if($score_keeper=="sk"){
// return $this->render('ScoreBoardViewerBundle:Viewer:keeper.html.twig',array('score_keeper' => $score_keeper));
// }
//returns scorboard view for all others
return $this->render('ScoreBoardViewerBundle:Viewer:view.html.twig',array('score_keeper' => $score_keeper));
}
You have a typo in your {% include %} statements. You are supposed to use : instead of . to separate blocks in template name.
Try this:
{% if score_keeper=='sk' %}
{% include 'ScoreBoardViewerBundle:Viewer:scoreboard_keeper.html.twig' with {'score_keeper' : score_keeper} %}
{% else %}
{% include 'ScoreBoardViewerBundle:Viewer:scoreboard.html.twig' %}
{% endif %}

I'm working with Twig in Craft and am trying to include a module I've made, I have added all the content into the modules in the CMS and saved it, they show on the page correctly, but a tonne of empty paragraph tags show also, does anyone know why this is?
Steps I took:
I have a twig file called "Abilities.twig", inside abilities I have the below code:
<p>{{ module.Abilities }}</p>
In Index.twig I have the below:
{% for module in entry.modals %}
{% include '_modals/Abilities' %}
{% endfor %}
An example below of how they show on the page
<p>This is the first example of an ability</p>
<p>This is the second example of an ability</p>
<p></p>
<p></p>
<p></p>
<p></p>
<p></p>
In the CMS the only modules that are shown are the top 2 examples, there are no empty modules saved.
If anyone can help would appreciate it
If you don't want to have the "extra" <p>'s you need to verify the content is not empty
{% if module.Abilities | trim != '' %}
<p>{{ module.Abilities }}</p>
{% endif %}
You can add an if statement in you loop
{% for module in entry.modals if module != null %}
{% include '_modals/Abilities' %}
{% endfor %}
I've been beating my head against this for a while, because while it's "easy" to do in raw PHP, the result is not extendable due to PHP's lack of decent built-in templating syntax. So I installed Twig assuming it would have a built-in explode function for iterating amongst blocks. But there seems to be no way of dividing content into an arbitrary number of subsections.
I considered using {% embed %}, but the document is to be styled according to which sections appear in the parent template. And in what order (which is variable; this is for a form with a lot of business logic in it.)
I've built the form in PHP and gotten it to work as a "very pretty" static page with easily an arbitrary number of subsections, all working and interactive regardless of which are displayed (based on e.g. user privileges), but templatizing it is the challenge.
The static (twigless) version relies on me exporting the parsed content to an array which can then be wrapped with the appropriately-styled div's for each visible section. This works, but requires me to use included html and object buffering which looks awful and would not be easy to maintain:
$content = include("form_content_html.php"); // return an object-buffered array
// I was including the escaped values here using if isset($data) and echo short tags.
foreach ($content as $section) { /* do something; */ }
$template = include("form_template_subsection.php");
$formview->addSubsectionTemplate($template);
echo $formview->addSubsection($content,$i++,$type);
// fill section of $type with $content[$i] if isset
echo $formview->addSubsection($content,$i++,$sometype);
// $types have different css class for certain effects
// etc. not the best approach.
(I need to escape all user / db content before binding it to the form values, but since the form fields are highly customized I separated them into their own content layer so that's the only layer that has content that needs to be escaped at present.)
So forget that, now I'm using Twig. (note: not Symfony2, as the project is on a shared webhost.)
I don't think there's a way of {%extend%}ing the parent template such that some of the child template blocks are "dropped into" the named parent template containers, with the rest ignored; which is what I'm looking for since that way I can put all the logic into the top level (which sections of the form to make visible, etc.) and pass in the values first.
Note that the style of the form sections is dictated by the structure of the parent template, not by the child content. E.g. section 1 may display content 1 and call css on content 2 in section 2; or section 1 and 2 with the same css may display different content.
If I split up the form into 15 content-only subtemplates, and then conditionally included them in the parent file, it would work. But that would seem to defeat the purpose of using a template engine? Although I suppose Twig makes it much easier to work with included files containing html snippets in this way, so let me know if that is a preferred solution.
Should I divide the content node up into numbered {% block1 %}, {% block2 %} etc. subsections and then renderBlock in my PHP view class?
If Twig had a {% section %}...{% section %} syntax allowing you to split up the template into chunks and then parse each chunk as an array of block elements... well, I half-expected that, and wish I could add one myself.
Is this a possible solution? From the Twig documentation:
Horizontal reuse is a way to achieve the same goal as multiple
inheritance, but without the associated complexity:
{% extends "base.html" %}
{% use "blocks.html" %}
{% block title %}{% endblock %}
{% block content %}{% endblock %}
The use statement tells Twig to import the blocks defined in
blocks.html into the current template (it's like macros, but for
blocks):
{# blocks.html #}
{% block sidebar %}{% endblock %}
Note: The use tag only imports a template if it does not
extend another template, if it does not define macros, and if the body
is empty. But it can use other templates.
Well, that's a bit thoroughly less than unclear.
(Does "it" refer to the imported template being able to use other templates, or does "it" mean a template can use more than one template, or both? and if the body is empty, does that mean the body of the imported block tag? If so then perhaps it is not a solution.)
Would it be possible to do something like this:
{# form_template.html #}
{% extends "form_content.html" %}
{% block section1 %}
<div class="{{ style1 }}"><div class="{{ style2 }}">etc.
{{ parent() }}
</div></div>{% endblock %}
Or this?
...
{# form.html #}
{% use "form_content.html" %}
{% for sections as i %}
{% block wrapper_elements %}{% block section{{i.name}} %}{% endblock %}
{% endblock %}
{% endfor %}
{# form_content.html #}
{% use "form_fields.html" %}
{% block section1 %}{% if field1 %}
Actual content here: {% block field1 %}{% endblock %} And here
{% else %} {% endif %}
{% endblock %}
{% block section2 %}More actual content here{% block section2 %}
But if so, how to iterate over the sections prior to calling each one in form.html?
I've found the solution, I think:
(From the Twig documentation)
The set tag can also be used to 'capture' chunks of text:
{% set foo %}
<div id="pagination">
...
</div>
{% endset %}
Ergo, set can be used to iterate over anonymous consecutive blocks:
{% set i=0, out=[] %}{# declare top scope #}
{% block initialize_content %}{# use once #}
{% set i=0, out=[] %}{# prevent dupes #}
{% set foo %}
<div id="pagination">...</div>
{% endset %}{% set out=out|merge({ i: foo}) %}{% set i=i+1 %}{% set foo %}
{{ escape_variables_here }} ... more html
{% endset %}{% set out=out|merge({ i: foo}) %}{% set i=i+1 %}{% set foo %}
{{ variables_all_scoped_to_same_context }} ... more html
{# so dividers can be moved "up and down" if necessary ... #}
{% endset %}{% set out=out|merge({ i: foo}) %}{% set i=i+1 %}{% set foo %}
{# ... like this. ^^a tag/macro could probably define this #}
{% endset %}{% set out=out|merge({ i: foo}) %}
{# or loop over i = 0..n or i = loop.index0 #}
{% endblock initialize_content %} {# end setter #}
{% block content %}
{% if key is defined and out.key is defined %}{{ out.key |raw }}{% endif %}
{# output top-scoped var (outputs nothing if setter not called) #}
{# the setter doesn't have to be in its own block, but that allows
the variables in the content to be redefined in setter's scope. #}
{% endblock %}

I am writting a tutorial and need to display some twig code... Problem: I'm writting that twig code on a twig view, so I need to find some way to write it raw, without interpretation.
Currently, I am using a twig extension to do the job:
$path = $this->kernel->locateResource($path, null, true);
return file_get_contents($path);
But I'm wondering if there is better solutions.
Found it. Twig has a built-in tag to to that job : verbatim.
{% verbatim %}
<ul>
{% for item in seq %}
<li>{{ item }}</li>
{% endfor %}
</ul>
{% endverbatim %}
I wanted to do something like this:
{{ include("tpl.html")|f }}
But that doesn't seem to work, it just printed tpl.html without any filtering, then I tried:
{% filter f %}
{% include "tpl.html" %}
{% endfilter %}
And it worked. I just wonder, why can't I use shorter one? Do I misunderstand something?
Thanks in advance.
Sorry for being that long to come back :-)
The fact is that the include function writes on the template.
If you do :
{% set s = include('FuzHomeBundle:Default:test.html.twig') %}
Which is not supposed to display something, you'll get the content of the file output anyway, and the s variable will be set to null.
If you do instead :
{% filter upper %}
{% include 'FuzHomeBundle:Default:test.html.twig' %}
{% endfilter %}
or
{% filter upper %}
{{ include('FuzHomeBundle:Default:test.html.twig' }}
{% endfilter %}
The filter tag will compile some code that control output buffer.
To apply a filter on a section of code, you have to wrap it with the filter tag:
{% filter f %}
...
{% endfilter %}
What you were trying originally is to filter a variable which in twig is defined by the double parenthesis:
{{ variable name|filter }}

I want to achieve the following thing:
I have a basic template for all of my pages, named "_page_base.twig". It contains the header and footer.
Then I have a Template for different areas of the page: "topic.twig", "section.twig" and "article.twig" - each of them extending the "_page_base.twig", thats working well so far.
Now I want to write my articles. I would love to save them as .twig file as well, since I can edit the complete markup in my editor and just upload it.
Since I can't say that my article files just extend "article.twig" (multiple inheritance is not possible) I could tell the "article.twig" that it should use blocks from my different article-content twigfiles.
The problem is: "use" statements have to be hardcoded!
My current solution is to add {% use "[PLACEHOLDER]" %} into the "article.twig" and then loading the template into a string, replacing the placeholder to the correct article-content.twig and then passing the whole thing to the template engine. What a mess.
Have you guys any idea for a better solution?
You can try with include tag. Since this tag accepts a dynamic name template to include, you just only need to define a variable which contains the name of article twig template.
{# on article.twig#}
{% set articles = ['someArticle.twig', ...] %}
{% for article in articles %}
{% include article %}
{% endfor %}
{# on someArticle.twig #}
... Article text ...
In the case of you need to customize some content inside of someArticle.twig you could stage the next level: embed tag. You should define a block tag inside of someArticle.twig, this block will be the placeholder to the custom values.
{# on article.twig#}
{% set articles=['someArticle.twig', ...] %}
{% for article in articles %}
{% embed article %}
{% block inside_text_article %}
... custom text ...
{% endblock %}
{% endembed %}
{% endfor %}
{# on someArticle.twig #}
... article text ...
{% block inside_text_article %}default values{% endblock %}
... article text ...

LiipThemeBundle might be a solution:
http://symfony2bundles.org/liip/LiipThemeBundle
Unless I am not understanding the question, displaying a single article only requires that it also extends __page_base.twig.
In the case that you would need to display multiple articles, you could have a template dedicated to showing a list of articles which would also extend __page_base.twig and pass the article list to this template.
