Variable does not exist twig symfony - php

Question

I have a controller that does this
/**
* #Route("/AjaxAddQuestionForm/{section}")
* #ParamConverter("section", class="AppBundle:Section")
*/
public function ajaxAddQuestionFormAction(Request $request, $section)
{
$question = new Question();
$addQuestionForm = $this->createForm(new AddQuestionType(), $question);
return $this->render('AppBundle:Form:ajaxAddQuestionForm.html.twig', array(
'section' => $section,
'addAjaxQuestionForm' => $addQuestionForm->createView(),
));
}
The ajaxAddQuestionForm.html.twig file looks like this
{% embed 'modal.html.twig' %}
{% block labelledby %}addnewquestion{% endblock %}
{% block modalId %}addnewquestion{% endblock %}
{% block modalHead %}
{{ 'client.modal.head'| trans }}
{% endblock %}
{% block modalBody %}
{{form_start(addAjaxQuestionForm)}}
<div>
{{form_widget(addAjaxQuestionForm.section, {value: section.id})}}
</div>
<div class="form-group">
{{form_label(addAjaxQuestionForm.name, null, {'label_attr': {'class': 'form-label'}}) }}
<span class="help"></span>
<div class="controls">
{{form_widget(addAjaxQuestionForm.name, {'attr':{'class':'form-control'}})}}
</div>
</div>
<div class="form-group">
{{form_label(addAjaxQuestionForm.category, null, {'label_attr': {'class': 'form-label'}}) }}
<span class="help"></span>
<div class="controls">
{{form_widget(addAjaxQuestionForm.category, {'attr':{'width':'100%'}})}}
</div>
</div>
{% endblock %}
{% block modalFooter %}
<button class="btn btn-default" data-dismiss="modal" type="button">{{'client.form.cancel'| trans}}</button>
<input class="btn btn-primary create" type="submit" value="{{'client.form.add.client'| trans}}">
{{form_end(addAjaxQuestionForm)}}
{% endblock %}
{% endembed %}
And finally I have an edit.html.twig that looks like this
<div aria-hidden="true" aria-labelledby="{% block labelledby %}{% endblock %}" class="modal fade" id="{% block modalId %}{% endblock %}" role="dialog" tabindex="-1">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button aria-hidden="true" class="close" data-dismiss="modal" type="button">×</button>
<h4 class="modal-title" id="myModalLabel">{% block modalHead %}{% endblock %}</h4>
</div>
<div class="modal-body">
{% block modalBody %}
{% endblock %}
</div>
<div class="modal-footer">
{% block modalFooter %}
{% endblock %}
</div>
</div>
</div>
</div>
{% include 'AppBundle:Form:ajaxAddQuestionForm.html.twig' %}
Now I get the following error:
Variable "addAjaxQuestionForm" does not exist in src/AppBundle/Resources/views/Form/ajaxAddQuestionForm.html.twig at line 9
Any idea what is wrong with my code?

Answer 1

In your edit.html.twig (assuming your addAjaxQuestionForm variable exists in it), you need to pass it on to the included twig.
{% include 'AppBundle:Form:ajaxAddQuestionForm.html.twig' with {'addAjaxQuestionForm': addAjaxQuestionForm} %}

Answer 2

Try to use
{{ render(controller('AppBundle:Section:ajaxAddQuestionFormAction',{'section':section})) }}
Instead of Include and you must add "section" parameter to ajaxAddQuestionFormAction.
We can help you more than that if you don't publish us all the code that concern the part of your problem.
I hope that helps

Answer 3

You should use render controller method instead of include
{{ render(controller(
'AppBundle:Form:ajaxAddQuestionForm',
{ 'section': section }
)) }}
