I am trying to get a single record from my database using doctrine. I am unsure how to use the findBy() method.
My current code is below:
$token = $em->getRepository('APIBundle:Token')->findBy();
Any help will be appreciated
You just need to include an array of what you want the findBy() method to use. Please see the below code:
$token = $em->getRepository('APIBundle:Token')->findBy(array('string' => $string));
Just name the 'string' part of the code as whatever field you are searching, and replace the $string with the variable.

I've got a controller action that's supposed to be looking for semi-duplicate entries in a collection, and removing them from that Entity's list. New ones should not have an ID yet, and existing ones do, so I'm running findOneBy() with an array of parameters to match on (leaving out ID).
I am baffled and deeply troubled by the error I am getting, where it finds the wrong entity! I've got some relevant code below, I hope this is just a dream or a silly mistake, I can't reproduce the output on my own windows development environment, but my co-worker was testing on his mac, and was getting errors, so I went on his machine and did some quick echoing to see what was going on. See the code and the result below.
CODE
foreach($entity->getTechnicians() as $tech) {
//find new addtions, see if they exist
if (!$tech->getId()) {
echo "Technician " . $tech->getFirstName() . " has no ID, trying to find one that does<br/>";
$found = $em->getRepository('TechnicianBundle:Technician')->findOneBy(array(
'firstName' => $tech->getFirstName(),
'lastName' => $tech->getLastName(),
'email' => $tech->getEmail(),
'residentEngineer' => $tech->getResidentEngineer(),
'officeNumber' => $tech->getOfficeNumber()
));
//if one with an ID already exists
if ($found) {
echo "found technician " . $found->getFirstName() . " that already has id " . $found->getId() . "<br/>";
...
OUTPUT
Technician Four has no ID, trying to find one that does
found technician khjvuov that already has id 7
Probably it's not a findOneBy() issue.
If without add/remove calls it works, it may be caused by modified current pointer of ArrayCollection so when $tech->getFirstName() is called it actually points to another entry.
You may try to iterate your collection like this:
$iterator = $entity->getTechnicians()->getIterator();
while ($iterator->valid()) {
$tech = $iterator->current();
... $entity->addTechnician()/$entity->removeTechnician()
$iterator->next();
}
It will create new ArrayIterator object, so you can modify underlying object preserving ArrayCollection's internal pointer.
This may be obsolete if you are running PHP7 (reference - Note box)
Ultimately, the findOneBy() method uses the load() method of the Doctrine ORM.
In the doc, the parameter $criteria is described as such :
#param array $criteria The criteria by which to load the entity.
You should probably dig deeper into Doctrine API to make sure, but there is a big chance that in the array you are passing as an argument, only the first key => value pair is taken into account (in your example, 'firstName' => $tech->getFirstName()).
If this is the case, you'll probably need to add your own custom method in your entity repository, one that would allow you to query your database with more advanced statements (using OR/AND or LIKE() in SQL for instance).
I'm trying to make a custom request in my repository with a WHERE clause inside an array field. I tried something like that, not working, but can better show my problem :
$qb ->andWhere( "p.addresses[:index] = :address" )
->setParameter( "index" , $p_idLang )
->setParameter( "address" , $p_address );
Extracted from the documentation about array type:
Maps and converts array data based on PHP serialization. If you need
to store an exact representation of your array data, you should
consider using this type as it uses serialization to represent an
exact copy of your array as string in the database. Values retrieved
from the database are always converted to PHP’s array type using
deserialization or null if no data is present.
Your query doesn't make sense. You have a few options though:
Retrieve p.adresses and check using php if p.adresses[$index] = $address
Try something much less reliable but that could work:
$val_length = strlen($p_address);
$qb ->andWhere( "p.addresses LIKE :indexAddress" )
->setParameter( "indexAddress" , "%i:$p_idLang;s:$val_length:$p_address%" );
Create a new entity and a relation oneToMany between this entity and the new one.
I'd definetely try option 3. Option 1 isn't an option if the array is big or will become big in the future. I wouldn't go for option 2, but as an experiment could be worth trying.
I'm new to Drupal. I looked here and on google for a while before asking, but I'm sure I can't find the answer because I don't know how to ask the question.
Here is what's going on. I'm using a custom module to load certain entities and then output them in a specific format for an application to access. The problem is that the NODE BODY contains special information and media files that should be converted. My goal is to obtain the HTML output that would normally be used on this field.
// Execute an EntityFieldQuery
$result = $query->execute();
if (isset($result['node'])) {
$article_items_nids = array_keys($result['node']);
$article_items = entity_load('node', $news_items_nids);
}
// Loop through each article
foreach ($article_items as $article) {
return $article->body[LANGUAGE_NONE]['0']['value'];
}
All of this works great. The only problem is that I get things like this in the output:
[[{"type":"media","view_mode":"media_original","fid":"283","attributes":{"alt":"","class":"media-image","data-thmr":"thmr_32","height":"400","width":"580"}}]]
or
*protoss_icon*
My goal is to find a way that these items are converted just like they are when these articles are viewed normally.
I've tried doing things such as:
render(field_view_field('node', $article, 'body'));
or
render($article->body[LANGUAGE_NONE]['0']['value']);
without success. Thanks for any help, I'm learning so I don't have a complete grasp of the process drupal uses to build output.
You can try something like this (this works only with nodes not with other custom entity types):
$node = node_load($nid);
$field = field_get_items('node', $node, 'your_field_name');
$output = field_view_value('node', $node, 'your_field_name', $field[$delta]);
the field_view_value returns a renderable array for a single field value. (from drupal api documentation)
I want to create a form using some fields from multiple entities. I have all the distinct entites needed already created and i am not using form classes. I need to know how to do to render a form and handle its data so i can save them to the correct tables in my database.
Here is a part of my controller in charge of doing that
public function createPublicSpaceAction() {
//My entities
$Room = new Room();
$GuestList = new GuestList();
$Guest = new Guest();
//I need to know what to do from here
return $this -> render('AcmeUserBundle:Default:Forms/createPublicSpace.html.twig', array());
}
I kept trying to find a solution and i came up with the idea that one form needs one entity. So maybe the solution would be to merge those entities in one so i can build the form easily. I would then have to persist data to corresponding tables. But i can't think of how to merge entities.
I figured out a temporary solution. For those who want to know, I manually created an entity that looks like a merge of all the entity I need. This new entity has no link with Doctrine therefore it cannot create a table. Its goal is simply to allow me to build up a form and be able to manipulate data through that form. I then assign all data submitted to corresponding entities fields and persist them to the database.
Once again i know this is not the best solution. But for some reasons I won't tell, it is for me at this moment. I hope this can help some that are in the same situation than me and do not hesitate to post links that could help or better ways to do that.
It is highly recommended to use form classes http://symfony.com/doc/current/book/forms.html#creating-form-classes
They are designed to save time and make a lot of things just easier.
However to answer your question consider the following. Your action needs to handel a post request. So catch the request object with the post data:
use Symfony\Component\HttpFoundation\Request;
public function createPublicSpaceAction(Request $request)
Then get a form builder intance and create the form:
$builder = $this->createFormBuilder();
$builder->add('floor', 'text', array(
'label' => 'Room floor',
'data' => $room->getFloor()
));
add as much form fields as you need. There are several built-in field types: http://symfony.com/doc/current/book/forms.html#built-in-field-types
Create the form:
$form = $builder->getForm();
Pass the form to your template:
return $this -> render('AcmeUserBundle:Default:Forms/
createPublicSpace.html.twig', array(
'roomForm' = $form
));
To get posted data within your action:
if ('POST' == $request->getMethod()) {
$data = $request->request->get("form");
}
And in your template you can render the form by yourself or let twig do the job:
{{ form_widget(form.floor)}}
So this are the most importend things to mention. However you should go through http://symfony.com/doc/current/book/forms.html They actually tell you everything I wrote down.
Good luck ;)
I would like to retrieve a cck field "field_info" in my form alter to insert into another table when user is submitting. This doesn't seem to work.
//mymodule_form_alter() implemented
function mymodule_form_mysubmit{
$test = $form['field_info']['#value'];
//insert stuff code
}
Is there any mistake in the code?
You say module_form_alter() is implemented, but just to confirm, you need to have the following in it:
$form['#submit'][] = 'mymodule_form_mysubmit';
Assuming you do, to get the value of field_info, your submit function should look like:
function mymodule_form_mysubmit($form, &$form_state) {
$test = $form_state['values']['field_info'][0]['value'];
}
$form_state contains the current state of the form being submitted. CCK always assumes that there could be multiple values for a field, so it always puts things in an array (hence ['field_info'][0]).
I found the solution
$test = $form['field_info'][0]['#value'];
