Symfony Forms is implant a collection of a great many other variations, that is good for edit associated organizations in a single form. In this post, you’ll carry out a type in order to edit a job group and, proper during the exact same mode, possible modify, carry out and take away of many Tag objects linked to one Task.

Tips Embed a couple of Forms

Second, let us perform a type to do the job organization, using a good CollectionType field of TagType forms. This will help us modify the Mark components of a job right within the task function in itself:

When the representative submits the form, the brand new recorded investigation towards labels community is utilized to build an enthusiastic ArrayCollection away from Tag things. This new range will then be intent on brand new tag world of the latest Activity and certainly will getting accessed thru $task->getTags() .

Yet, so it works great, but simply to edit established labels. It generally does not have developed yet , to incorporate the latest tags or erase established of them.

You could implant nested collections as numerous account off as you including. However, if you utilize Xdebug, you can also found a maximum function nesting quantity of ‘100′ hit, aborting! error. To fix it, increase the xdebug.max_nesting_height PHP mode, otherwise give each form profession yourself playing with function_row() in place of helping to make the entire form at the same time (elizabeth.grams setting_widget(form) ).

Enabling “new” Tags to your “Prototype”

In earlier times you additional one or two labels to the task regarding operator. Today allow users include as many level versions while they need directly in the newest web browser. This requires some JavaScript code.

But first, you will want to allow the setting range know that unlike exactly two, it does discovered a phone number away from tags. Otherwise, you will notice a great “This form shouldn’t contain even more areas” mistake. This is accomplished on the create_include 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 design.labels.vars.model is a type element that appears and you will feels same as the person mode_widget(mark.*) elements within your getting loop. As a result you could potentially label means_widget() , form_row() otherwise function_label() involved. You could also want to provide singular of the sphere (age.g. title occupation):

    For many who give the “tags” sub-function at the same time (age.g. function_row(mode.tags) ), the data-prototype characteristic try instantly placed into the latest that has div , and you should adjust next JavaScript correctly.

    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
