How exactly to Implant some Versions

How exactly to Implant some Versions

Symfony Versions can also be embed a collection of many other forms, which is good for change related agencies in one setting. On this page, you’ll be able to manage an application in order to revise a role class and, proper in same setting, you can revise, perform and take away of many Mark items linked to you to definitely Task.

How to Implant a collection of Forms

2nd, why don’t we would an application to do the job entity, having fun with a beneficial CollectionType realm of TagType versions. This can allow us to customize all of the Level areas of a job proper into the task setting in itself:

In the event the associate submits the form, the fresh submitted research into the labels career can be used to create a keen ArrayCollection of Level stuff. The fresh collection will then be set on the newest tag field of the latest Activity and will be utilized thru $task->getTags() .

So far, it works great, but just to change present labels. It doesn’t have developed but really to incorporate the fresh new labels otherwise delete existing of them.

You might embed nested choices as many profile down because you for example. However, if you are using Xdebug, you can located a maximum function nesting level of ‘100’ hit, aborting! mistake. To solve so it, boost the xdebug.max_nesting_height PHP means, or offer for each mode industry by hand using setting_row() rather than leaving the entire mode immediately (age.g means_widget(form) ).

Making it possible for “new” Tags on “Prototype”

Prior to now your added one or two tags on task from the operator. Now allow the users add as numerous level forms as they you would like in direct the newest internet browser. This involves a little bit of JavaScript code.

However, basic, you should let the form collection know that rather than exactly a couple, it does discover a phone number of labels. Or even, you will observe a beneficial “This form shouldn’t include even more industries” error. This is done towards the enable it to be_put choice:

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 form.tags.vars.prototype try a form element that appears and you may seems identical to amateurmatch seznamovací aplikace the individual form_widget(tag.*) aspects within your to own circle. Because of this you could potentially name mode_widget() , form_row() or means_label() inside. You could actually prefer to bring singular of their areas (age.g. title community):

For those who promote the “tags” sub-means simultaneously (e.grams. form_row(function.tags) ), the info-model attribute try immediately put in the containing div , and you need to to change another JavaScript appropriately.

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

The brand new addFormToCollection() function’s occupations should be to utilize the research-model characteristic to dynamically add an alternate setting when this connect is engaged. The information and knowledge-model HTML contains the tag’s text message type in element with a name away from activity[tags][__name__][name] and you can id out-of activity_tags___identity___term . The new __name__ was a great placeholder, which you are able to replace yet another, incrementing count (e.grams. task[tags][name] ):

Now, each time a user clicks the latest Add a tag link, an alternate sub means can look for the web page. In the event that means try recorded, one this new mark models was converted into the Level things and you may put in the brand new labels possessions of your own Task object.

And work out dealing with these the fresh new tags convenient, put a keen “adder” and you may an effective “remover” opportinity for brand new tags from the Task class:

With the help of our several alter, if setting try recorded, for each and every the Tag target are placed into the job category of the getting in touch with the latest addTag() method. Before this change, these people were extra internally because of the form by calling $task->getTags()->add($tag) . Which was great, however, forcing the usage the “adder” means helps make dealing with this type of this new Mark things convenient (particularly if you are playing with Doctrine, you will discover throughout the next!).
