I create a form wherein the user enters some values but I now need to retrieve those values to display in a table. I'm unsure about how to achieve this. I'm working with the intro package and new to the system. I've read some tutorials but nothing about achieving this.
Edit: I should mention that I need to persist these values in a database first before attempting to display it.
Probably, the easiest way is to use Powermail extension, which handles many cases.
You could save the submitted data in dB and show it after with Your extension, or TypoScript configuration.

I have a question about dynamic forms. The current situation is that we have a template driven form and the requirement is that the user can reorder the controls and also set some to invisible. For reordering we use dragula but for loading the stored setting we need to generate the form dynamically. We want to keep the template driven aproach and now my idea was to use the ngComponentOutlet in combination with the ContentChildren of the template to generate the form with the stored setting. Is this possible does anyone have another idea ? If possible please provide an example.
I am looking for best practices on SYMFONY FORM handling to achieve the following standard page (surprisingly I haven't found anything similar existing yet on SO).
Here is a shema of what I want to achieve:
As you can see at the top there is a SYMFONY FORM to filter the results that should be displayed.
It displays a table and each tuple of the table should permit to open another SYMFONY FORM kind linked to the tuple.
I am in the process of learning SYMFONY FORM, so far, I can manage to create the top row FORM to set the filter that'll apply to the table display.
But I wonder if anyone has experience on the second part: Displaying the table that embed as well many forms of a similar kind -That seems a bit more complex. I read about TWIG.EXTENSION and FORM.COLLECTION, I'll investigate that. But if someone could save me to re-invent the wheel and lead me to some direct shortcut, I'd be really grateful.
No idea if it's the best practice, but one way to do it would be to create a new property for your entity being listed in this table, called $editionForm (without mapping it to the database) for example.
Then, either throught a custom loop or by listening to a doctrine (or any ORM you use) hydration event (or triggering such an event if you don't use any ORM), fill the property with the generated form, probably within a dedicated service.
Then, just use it in your template like this :
$entity->getEditionForm()->render()
I am a Django noob and have a situation that goes beyond the basic documentation, etc.
I am updating an ordering webpage that has a form structured as follows:
several text boxes, etc to gather general info (name, date, etc)
two separate tables for selecting (via checkbox) catalogs that are generated/managed using endless_pagination. Each table can have thousands of records, hence the endless_pagination. The first column in each table is a checkbox with value = catalog.id.
a textbox where the user can manually enter catalog IDs
a submit button
I am not sure how to keep track of what a user has selected in the two paginated tables since the checked boxes are lost when choosing a different page. Also, when the user flips back and forth between the pages, the previoulsy checked catalogs will need to be re-checked(since the checked state is not maintained). I am also not sure which tool(s) to use to deal with this.
My thought is to use JavaScript (with which I have minimal experience) to update a list of catalog IDs whenever a checkbox is checked/unchecked and:
- and attach that list to the form or
- update a variable in the form or
- send as a variable separate from the form, whichever is possible/makes more sense.
I'm hoping that maintaining a list of catalog IDs is possible because the next iteration of this form will likely include some sort of filtering so I'm trying to devise a solution that will not have to be reworked later.
I have reviewed a lot of posts but I believe the closest solutions are rendered useless because of the endless_pagination.
Let me know if further clarification is required. Thanks in advance for any suggestions.
UPDATE
I tried using JavaScript to store the catalog IDs in an array when a checkbox is checked. This does not work when a user selects another page in the pagination. The array of checked catalog IDs is lost when the page 'reloads'.
I'm running into this problem right now as well. I'm handling this by writing the checked items to localStorage so they carry across to page 2, 3, etc.. as well as show up as already checked when you go back to page 1. Then every time the page loads, either find and check the existing checkbox, or create a hidden input with the appropriate name and value and append it to the main form.
var selected_items = []
function add_item_to_checkbox(item) {
localStorage.setItem('selected_items', JSON.stringify(selected_items));
checkbox.on("click", add_item_to_checkbox);
bahh... Just look at my jsfiddle it's easier to read and yeah. I don't have to type JS into a textarea on stackoverflow.
Here is my javascript minus a few things that are specific to my code. I'm sure it could be improved upon but it works really well for my application.
I have a form with a single text field.
On submit I would like to display another form.
I can use RESPONSE.redirect() and pass it in the query string but I would rather not.
I don't want to use a SESSION variable.
I would like to display a second form which can read this value from the request variable.
I have looked at collective.z3cform.wizard but it is not obvious how to do this.
Trying to call the view() from the button handler does not seem to have any effect.
I fall in the same lack of functionality.
For what I know, z3c.form does not support this kind of traversing.
You may remember that this functionality worked well with CMFFormController.
Actually to do this, cmfformcontroller used session machinery.
So, you don't want to use session but that's the way. At least I do so, and I'm happy.
In this way there's no need of a wrapping tool like z3c.form.wizard.
hth,
alessandro.
collective.singing has a non-session based wizard which uses hidden fields to store results of intermediate steps.
hey has anyone successfully done this, do you have a simple example of this? the goal is to build a frontend to create the form thus the form variables being saved in the database.
do i need to know what fields are being saved /mirror with another table or can one do this in the same table?
Probably you are searching for this?
