Yii Mailer PHP Error Array to string conversion

Question

The problem is the checkboxlist selection which is a multiple select. When I remove the following mailer code from the controller, the form is emailed... '{serviceItem}' => $model->selection,

In the model, the following explode and implode is used for putting the selection into the db table correctly...

public function afterFind()
{

    $this->selection=explode(',',$this->selection);

        return true;

}

/*implode your selection */
public function beforeSave()
{
    $this->selection=implode(',',$this->selection);
        return true;


}

If implode beforeSave...

[quote="php manual"] Returns a string containing a string representation of all the array elements in the same order, with the glue string between each element.[/quote]

And the mailer $message = strtr returns a string from the array...

[quote="phpmanual"]strtr - If given two arguments, the second should be an array in the form array('from' => 'to', ...). The return value is a string where all the occurrences of the array keys have been replaced by the corresponding values...

$message = strtr ('Submitted on: {submissionDate}
Name: {firstName} {lastName}

Service Item: {serviceItem}

Visitor Comments: {message}', array(
'{submissionDate}' => $model->date,
'{firstName}' => $model->firstName,
'{lastName}' => $model->lastName,

'{serviceItem}' => $model->selection,

'{message}' => $model->comments));

Q. Why is there an error? and...

Q. What is the solution for the $model->selections to be sent in the email?

Answer 1

Q. Why is there an error?

Answer:

First strtr() expects the array to be of the form array('stringFROM'=>'stringTO') and not array('stringFROM'=>array(...)).

You are getting the second format(and hence the error) because $model->selection is an array, since you have done an explode() in afterFind().

afterFind() is called whenever you load a model with any of the find methods of CActiveRecord(i.e find(), findAll(), findByPk(), findByAttributes(), and so on), and if i am correct you are calling one of those of methods to get your current model.

Q. What is the solution for the $model->selections to be sent in the email?

Answer:

In this case you can simply do an implode() again, to get a string:

'{serviceItem}' => implode(',',$model->selection);
