Following is how the form is rendered.
<fieldset class="properties">
{% block form_content %}
{{ form_widget(form) }}
{% endblock %}
</fieldset>
Now I can access any form field in this template, like {{ form.description }}, it's all good . But here I have a collection field in this form, let's call it collection, I have built a custom field type for this, the block template for this custom type is customCollect_widget, everything until this point is fine, but if I want to access the collection object in this widget template, I got an error saying the field name does not exist in the form object.
Here's my widget template:
{% block customCollect_widget %}
{% spaceless %}
{% for aa in form.collections %}
<div>something</div>
{% endfor %}
....
<% endblock %}
The problem, as I figured, is that the form isn't the same object that's passed to the code above. Is there any workaround to it?
Ha, I solved it. In the collection type widget template, the form variable is referencing the form field type itself, in this case, the collection type. So to loop through the collection in the widget block, you just do {% for child in form %}.

I have everything working correctly and now I'm trying to work with form themes. This is my code to generate the form without a theme.
{% extends 'base.html.twig' %}
{% block body %}
{% include 'menu/menu.html.twig' %}
{% if addpost is defined %}
<div id='add_post_form'>
{{ form_start(addpost) }}
{{ form_widget(addpost) }}
{{ form_end(addpost) }}
</div>
{% endif %}
{% endblock %}
But when I'm adding a form-theme with the following code
{% form_theme form 'form/form_div_layout.html.twig' %}
I get this error:
Variable "form" does not exist
When i execute this without the line, I'm getting the following error:
Unknown "form_help" function. Did you mean "form_rest", "form_end"?
the form_div_layout.html.twig contains the code found at github symfony twig form theme
At my config.yml I've added the following under the twig section,
form_themes:
- 'form/form_div_layout.html.twig'
.
either not, i still have this error
what is missing ???
My file structure
If all your forms are going to use the same theme you only need to add the line in your config, but if you want a particular form theme in a particular template you can use the template tag.
The reason you're getting the 'form is not defined error' is because you don't have a variable called form passed the the template, your form variable is called addpost, so you need to use
{% form_theme addpost 'form/form_div_layout.html.twig' %}
I was wondering if someone can tell me how to hide the action links from the list view base on a status column.
More details: I have a list view in which shows a list of items, In this list I have column named status. For each record in this list in which status is set to close, I would like to hide the edit/delete and other custom actions links from the list. Is this doable? if so, how?
Thanks
A possible solution is to override just the item_actions Twig block in the list.html.twig template used by that entity. In practice, if the entity is called Order, a template like this should work:
{# app/Resources/views/easy_admin/Order/list.html.twig #}
{% extends '#EasyAdmin/default/list.html.twig' %}
{% block item_actions %}
{% if item.status != 'close' %}
{{ parent() }}
{% endif %}
{% endblock item_actions %}
I have a Customer object, which has many Emails.
I'm building a form for my customer, and I've added his emails as a collection. In my template, I render the emails portion like this:
<h4>Emails</h4>
{% for email in form.emails %}
<li>
{{ form_row(email.addr) }}
{{ form_row(email.isPrimary) }}
</li>
{% endfor %}
...
{{ form_rest(form) }}
This works fine, except if the customer has no emails. Then, form_rest() renders the label 'emails' at the bottom of my template.
Why does this only get rendered when form.emails is empty? How can I customize it? (Note I've already customized my label rendering for other form elements, and I don't want it to be the same for these 'collection labels'.)
I usually solved this problem this way:
{% for email in form.emails %}
{# ... #}
{% else %}
{{ form_widget(form.emails) }}
{% endfor %}
Unless someone suggests a better way of doing this.
I've set my forms to use a custom template (that produces a DL) and that works fine
twig:
form:
resources:
- 'myBundle:Form:row.html.twig'
But then I want to customise one row of one form and I think I have to do this
{% form_theme edit_form _self, ' %}
{% block _startYear_row %}
{% block form_row %}
{{ parent() }}
<div id="startCalendaryear"></div>
{% endblock %}
{% endblock %}
That make the entire form inherit from _self and loses the customisation of row.html.twig.
How can I set a custom template for all forms while still overriding a single row on one of them?
I have a xxx.html.twig file which shows a page, but when I want to refresh the page with different data and just update it with new data, I have a select and a submit button for it.
The thing is that I don't know how do I call an action in the controller which I pass parameters to from my twig and call for new data and then I render the same twig template again with new parameters.
How do I do so?
Here are a few different ways:
{{ render(app.request.baseUrl ~ '/helper/test', {"hostid2": hostid } ) }}
or
{% include 'MyCoreBundle:Helper:test.html.twig' with {"hostid2": hostid } only %}
or
{% render controller("MyCoreBundle:Helper:test", {'hostid2': hostid}) %}
Symfony 2.1:
{% render 'YourBundle:YourController:yourAction' with {'var': value} %}
Symfony 2.6+:
{{ render(controller('YourBundle:YourController:yourAction', {'var': value})) }}
And, of course, read the documentation.
I think some parts are depricated here.
To make the include work in latest Symfony 3.1.10, I solved it like this:
{% extends 'base.html.twig' %}
{% block body %}
{{ include('AppBundle:Default:inner_content.html.twig') }}
{% endblock %}
Note: include() with parentheses.
Then all the variables are included from the parent template. If you like to restrict some variables in the child template, you use with ... only (look over)
