I have already set the value of CSRF_PROTECTION to TRUE in CI config.php, Also the FORM helper is already set to autoload.
I have used form_open() and form_close() in CI forms.
But my problem is that the value of <?=$csrf['hash'];?> is always blank. Ideally there should be some CSRF token.
You need to place following array before <?=$csrf['hash'];?>
$csrf = array(
'name' => $this->security->get_csrf_token_name(),
'hash' => $this->security->get_csrf_hash()
);
Then it will show the hidden field with CSRF token.

But if use form_open() and form_close() then it automatically generate a hidden field contain CSRF token.

up until this point I have essentially been using resource routing. One of my routes is for projects. If I create a project and then SHOW it, I see a URL in the form of
myUrl/projects/1
On the show page for a project, I want to be able to add a document. I have set up the relationships so a project can have one document and a document belongs to a project. I then set up the following route to handle the saving of the documents data
Route::post('projects/{id}/docOne', 'DocOneController#store');
So I add an a form in projects/show.blade.php, which opens like so
{!!
Form::model(new App\DocOne, [
'class'=>'form-horizontal',
'route' => ['docOne.store']
])
!!}
I then have my form fields and a save data button. Because of this new form within my projects show page, when I now show a project, it complains that the route for this new form is not defined.
How can I get this route to work within the projects show page?
Thanks
First of all you need to define a route name to your route, if you want to call it by his name.
So your route would be like:
Route::post('projects/{id}/docOne', [ //you need an array to set a route name
'as' => 'docOne.store', //here define the route name
'uses' => 'DocOneController#store' //here the callback
]);
Second you need to change your laravel form to use your route name and set the id
{!! Form::model(new App\DocOne, [
'route' => ['docOne.store', $project], //if you have setted the id variable like $id blade it gonna retturn it automatically only by passing the object, else, you can set $project->id
'method' => 'POST']
) !!}
EDIT:
You can't get an instance of a model on your view.
So the part:
{!! Form::model(new App\DocOne,
gonna fails every time you trye, also, the form:model needs an instance of a class that should have your vars filled with the info that the inputs should have (when you edit it).
You have two solutions:
If it's a new Doc and never before exist on your dataBase
I recomend to change your
Form::model
to:
Form::open
if it's a Doc thath already exist on your DB, like an edit, so in your controller you need to pass your existing Docas $docand remplace the: {!! Form::model(new App\DocOne, to:
{!! Form::model($doc,
and it works.
Form model was created to fill the input values with the data existing in your object instance, like when you edit someting.
So you need to have a correct instance.
Another think it's the MVC scope, a view shouldn't have acces to models, except if are passed by the controller.
Ok that's all.
I am creating a simple Blog system with symfony2. Each blog Post is bound to a certain amount of Tags.
Tags can be selected with checkboxes when creating a new blog post. Now I want to be able to dynamically add new tag-checkboxes to the form.
The AJAX part is done and working, I can add new tag names to the Tag entity and append the new checkboxes to the form.
The problem is when I submit the form, symfony2 doesn't recognize the new added tags because they don't belong to the Tag entity yet (at the time the form was generated).
For example: after submitting the form, I dump:
$tags = $form->get('tags')->getData();
The controller ignores the tags that were added through ajax.
I know it has to be solved with events somehow, I already read this documentation: http://symfony.com/doc/current/cookbook/form/dynamic_form_modification.html but can't figure out how to implement it for this specific case.
Here is my form builder for "PostType":
$builder
->add('title')
->add('content', 'textarea')
->add('tags', 'entity', array(
'class' => 'Bundle:Tag',
'property' => 'name',
'multiple' => true,
'expanded' => true,
))
->add('save', 'submit')
;
You can try to use this: Form Collection
Make sure you persist the newly added Tags before submit the form, and the checkboxes has the right names and values.
Names should be like "post[tags][]" and values should be the database ids of the Tag entities.
I think CakePHPs JsHelper is pretty neat to use for AJAX form submissions. Normally you just set the DOM element to update with the new content and the JsHelper takes care of the rest. A normal submit button could look like:
echo $this->Js->submit('Submit', array(
'update' => '#a-div',
'url' => 'some-url'
);
Now, I want to update 2 or 3 different DOM elements and my AJAX response type will be JSON with 2 or 3 key pairs. So to my question.
How can I capture the JSON response data and pass THAT DATA to an independent callback function that I have written myself where I can parse the response and update the relevant DOM elements with the value pairs? What is the correct syntax for that? I realise I could probably skip using the JsHelper and create my own submission, but I don't want to do that in this instance.
I found the right answer:
echo $this->Js->submit(
'Lägg en i varukorgen',
array(
'url' => array('controller' => 'products', 'action' => 'ajax_basket'),
'id' => 'basket-add-submit',
'success' => 'myFunction(data);',
)
);
At the success callback, data holds the JSON being returned.
Forget the JsHelper and write jquery code yourself.
echo form_textarea('general4', set_value('general4'), 'class="general"');
the set_value function doesn't seem to work with the textarea so I tried this:
<textarea name='general4' class="general"><?=set_value('general4')?></textarea>
But still not working, any ideas?
to use form_textarea() in CI you pass parameters rows and coloumns as below
$data = array(
'name' => 'txt_area',
'id' => 'txt_area',
'value' => 'johndoe',
'rows' => '5',
'cols' => '10',
'style' => 'width:50%',
);
echo form_textarea($data);
for more details refer CI user guide https://www.codeigniter.com/user_guide/helpers/form_helper.html#form_textarea
What you did is set the name of the textarea field to: 'general4'. I think what you meant to do is return an actual string to your textarea to pre-populate it with data from a post request or a MySQL database or something like that. There are a number of ways to achieve this.
Method 1:
Set a second parameter in the set_value() function eg:
<textarea name='general4' class="general"><?=set_value('general4', $foo)?></textarea>
Method 2:
You could always use the built in form_textarea() function. Docs found here
Examples:
Generic
<?=form_textarea('name', 'value', 'attributs')?>
Case
<?=form_textarea('general4', $general4, "class = 'foo'")?>
From the CI Documentation:
set_value()
Permits you to set the value of an input form or textarea. You must supply the field name via the first parameter of the function. The second (optional) parameter allows you to set a default value for the form.
<input type="text" name="quantity" value="<?php echo set_value('quantity', '0'); ?>" size="50" />
The problem was that I didn't need the textfield to be required. So I didn't set any rules in the action url. So I added this:
$this->form_validation->set_rules('general4', 'general question' , 'trim|xss_clean');
And it worked fine!
When I try to populate a form field which is not required in form validation doesn't repopulate. Let's say I have a field but I don't want it to be required but I want it to be repopulated. How can I do it ? I think this is a bug for codeigniter.
This piece of code solved my problem. But I have to use helpers for that. At least I have a solution.
function value_field($field, $default='') {
return (isset($_POST[$field])) ? $_POST[$field] : $default;
}
You have to set a validation rule on a field in order for it to repopulate on an invalid submission. Luckily, you can pass regular PHP functions, not just validation rules, to the set_rules() method so you could just set trim or something rather than required.
$this->form_validation->set_rules('your_field', 'Your Label', 'trim');
That will repopulate the field and not make it a required field.
Using the form helper's set_value() works even for non-required fields, I'm not sure where your problem lies...
echo form_input(array('name' => 'username', 'value' => set_value('username'));
