Symfony Forms is also implant some a number of other variations, that’s advantageous to edit relevant organizations in one single means. In this article, you are able to would a form so you can change a task class and, proper inside exact same mode, you can modify, manage and take off of several Tag things linked to that Task.
Just how to Implant a collection of Versions
Second, let us perform an application to do the job entity, playing with good CollectionType field of TagType versions. This may help us tailor all of the Mark components of a job correct inside activity function itself:
In the event the representative submits the form, the new submitted study on tags profession is utilized to build an enthusiastic ArrayCollection of Level items. The fresh range will be set on the fresh tag realm of the new Activity and can end up being reached via $task->getTags() .
Yet, it works great, but only to modify existing labels. It does not allow us but really to provide the tags otherwise delete established of these.
You might embed nested selections as many profile down because you eg. Although not, when you use Xdebug, it is possible to discovered a max mode nesting amount of ‘100’ attained, aborting! error. To fix that it, increase the xdebug.max_nesting_level PHP mode, otherwise bring for each form career yourself having fun with mode_row() unlike rendering the whole function immediately (e.grams function_widget(form) ).
Making it possible for “new” Tags with the “Prototype”
Prior to now you added a few tags on task throughout the controller. Now let the profiles include as much level variations because they need directly in the fresh new browser. This involves a bit of JavaScript password.
But first, you should allow means collection know that in lieu of precisely one or two, it does found a telephone number away from labels. If you don’t, you will observe a good “This type must not incorporate extra fields” mistake. This is accomplished on allow it to be_include option:
The allow_add option also makes a prototype variable available to you. This “prototype” is a little “template” that contains all the HTML needed to dynamically create any new “tag” forms with JavaScript. To render the prototype, add the following data-prototype attribute to the existing
- in your template:
The design http://www.datingranking.net/cs/coffee-meets-bagel-recenze/.tags.vars.prototype was a form ability that looks and you may feels identical to the person setting_widget(tag.*) points inside your for cycle. This means that you could call means_widget() , form_row() otherwise function_label() with it. You can also will give one of its fields (age.g. title career):
For individuals who provide the whole “tags” sub-setting at the same time (elizabeth.g. setting_row(mode.tags) ), the knowledge-prototype characteristic was instantly placed into brand new which has div , and you should to alter the next JavaScript accordingly.
Now add some JavaScript to read this attribute and dynamically add new tag forms when the user clicks the “Add a tag” link. Add a
