Error when adding/editing entry in admin module

[LrsK]

I get this error when trying to run backend_dev.php/user, then clicking "New" and adding some data:

Warning: array_key_exists() [function.array-key-exists]: The first argument should be either a string or an integer in C:\xampp\htdocs\sf_sandbox\lib\symfony\util\sfParameterHolde r.class.php on line 53

Warning: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\sf_sandbox\lib\symfony\util\sfParameterHolde r.class.php:53) in C:\xampp\htdocs\sf_sandbox\lib\symfony esponse\sfWebRespons e.class.php on line 335

Also, the fields that I filled in are returned with *Required tags, indicating that they weren't submitted somehow. Even the CSRF token is missing according to the response from the form.

I followed the "Admin generator" tutorial, so I'm not sure what went wrong. ~ ~


Thanks for any help!

Hi,

I had the same problem, but not with the admingenerator.
I set a new widgetschema in my formclass, to overwrite the widgetschema in the generated baseclass.

In the docs it says that the configure method is used in the users formclass, so you don't have to rewrite the whole setup routine of the generated baseclass.

Unfortunately, when you call setWidgets, a new (empty) widgetSchema is created; so this also overwrites the nameformat.

My mistake was that I didn't explicitly set the nameformat for the widgetschema in the configure method again, as well as the errorSchema. Just had to copy them from the baseclass.



However, Symfony shouldn't raise this error. I looked a bit into the code and found, that the default value for a new widgetSchemas nameFormat is '%s'. The getName method of the form checks for '%s' and returns false for the name, but the value of getName is just passed on to the getParameter methods and this produces the array error. False is no valid array index ~ ~

The getParameter method looks like this:

Code: Select all

public function getParameter($name, $default = null)
{
     return $this->parameterHolder->get($name, $default);
}


and parameterHolder->get looks like:

Code: Select all

public function & get($name, $default = null)
{
    if (array_key_exists($name, $this->parameters))
    {
        $value = & $this->parameters[$name];
    }
    else
    {
         $value = sfToolkit::getArrayValueForPath($this->parameters, $name, $default);
    }

    return $value;
}


It crashes, because array_key_exists itself can't handle 'false' as $name. So either build a check for this and give the poor symfony hacker a proper error message, so he doesn't have to read through the whole sourcetree ~ ~ ; or leave it that way.
Sounds dumb, but I think this method is really trimmed for performance. Request Parameters are frequently accessed and that shouldn't take too long.

Please give me feedback. Shall I file a bug report for this? Or just keep this in the forums, so other devs know what's wrong, when they get this error.

Hi.

I had the same problem with Symfony 1.2 and without the admin generator.

In fact, I added the setWidgets and setLabels in my /lib/form/XXXForm.class.php and the error was shown. Once i've added

Code: Select all

$this->widgetSchema->setNameFormat('XXX[%s]');

    $this->errorSchema = new sfValidatorErrorSchema($this->validatorSchema);


in this file (copied from base form class), it worked nice.

Weird... but thanks ~ ~

I have exactly the same problem after generating an admin module.
Table with 3 primary keys, I changed the routing.yml to

Code: Select all

column:               code_id/:employe_id/:date

and added in lib/model/Codeemploye.php :

Code: Select all

public function getPrimaryKey()
  {
    return $this->getCodeId().$this->getEmployeId().$this->getDate();
  }


Deleting works, but I cannot add or update. I have

Code: Select all

Warning: array_key_exists() [function.array-key-exists]: The first argument should be either a string or an integer in /home/XXX/lib/vendor/symfony/lib/util/sfParameterHolder.class.php on line 53

Any idea?
Thank you.

It seems object doesn't get correctly by routing.
Because when I disable CSRF I got:

Code: Select all

Fatal error: Call to undefined method sfRoute::getObject() in /home/XXX/cache/backend/dev/modules/autoCodeemploye/actions/actions.class.php  on line 93

How explain...
First time I worked on this project was several months ago and I forgot I changed /lib/form/XXXForm.class.php.

So I added:

$this->widgetSchema->setNameFormat('XXX[%s]');

$this->errorSchema = new sfValidatorErrorSchema($this->validatorSchema);

and it finally works...

wanted to give a big thanks for this. BIG thanks.
