Cakephp table query - forms

I have a members table. It has these columns:
ID
fname
lname
parent
spouse
I want 'parent' field to have select option in a form which uses 'fname' & 'lname' and store it in 'parent' field. I have tried to do this Members controller:
$results = $this->Members->find('list',
array('order'=>array('fname DESC')));
$parent = $results->toArray();
I am calling $parent variable as an input. However that method doesn't work. I don't know how to figure it out.

When calling list you can configure the fields used for the key and value with the keyField and valueField options respectively.
Doc: https://book.cakephp.org/3.0/en/orm/retrieving-data-and-resultsets.html#finding-key-value-pairs
Like this
$query = $articles->find('list', [
'keyField' => 'slug',
'valueField' => 'title'
]);
In your case it will be like this
$results = $this->Members->find('list', array(
'keyField' => 'ID',
'valueField' => 'parent'
'order'=>array('fname DESC'),
));
$parent = $results->toArray();

How to select a calculated value including parameter using Zend FW?

I'm using Zend FW and have a select with specified columns to be selected, e.g.
$select = $this->_db->select();
$select->from( array("t" => 'table'), array( 'id', 'name', 'some_number'));
Now I want to get the some_number value multiplied by some given parameter, like :
select id, name, (some_number * $param) from table;
How to do that?
Got it, using Zend_Db_Expr. If someone else needs... That works for me:
$select->from( array("t" => 'table'),
array( 'id', 'name', 'new_number' => new Zend_Db_Expr('some_number * ' . $param ) )
);

Yii CJuiAutoComplete for Multiple values

I am a Yii Beginner and I am currently working on a Tagging system where I have 3 tables:
Issue (id,content,create_d,...etc)
Tag (id,tag)
Issue_tag_map (id,tag_id_fk,issue_id_fk)
In my /Views/Issue/_form I have added a MultiComplete Extension to retrieve multiple tag ids and labels,
I have used an afterSave function in order to directly store the Issue_id and the autocompleted Tag_ids in the Issue_tag_map table, where it is a HAS_MANY relation.
Unfortunately Nothing is being returned.
I wondered if there might be a way to store the autocompleted Tag_ids in a temporary attribute and then pass it to the model's afterSave() function.
I have been searching for a while, and this has been driving me crazy because I feel I have missed a very simple step!
Any Help or advices of any kind are deeply appreciated!
MultiComplete in Views/Issue/_form:
<?php
echo $form->labelEx($model, 'Tag');
$this->widget('application.extension.MultiComplete', array(
'model' => $model,
'attribute' => '', //Was thinking of creating a temporary here
'name' => 'tag_autocomplete',
'splitter' => ',',
'sourceUrl' => $this->createUrl('Issue/tagAutoComplete'),
// Controller/Action path for action we created in step 4.
// additional javascript options for the autocomplete plugin
'options' => array(
'minLength' => '2',
),
'htmlOptions' => array(
'style' => 'height:20px;',
),
));
echo $form->error($model, 'issue_comment_id_fk');
?>
AfterSave in /model/Issue:
protected function afterSave() {
parent::afterSave();
$issue_id = Yii::app()->db->getLastInsertID();
$tag; //here I would explode the attribute retrieved by the view form
// an SQL with two placeholders ":issue_id" and ":tag_id"
if (is_array($tag))
foreach ($tag as $tag_id) {
$sql = "INSERT INTO issue_tag_map (issue_id_fk, tag_id_fk)VALUES(:issue_id,:tag_id)";
$command = Yii::app()->db->createCommand($sql);
// replace the placeholder ":issue_id" with the actual issue value
$command->bindValue(":issue_id", $issue_id, PDO::PARAM_STR);
// replace the placeholder ":tag_id" with the actual tag_id value
$command->bindValue(":tag_id", $tag_id, PDO::PARAM_STR);
$command->execute();
}
}
And this is the Auto Complete sourceUrl in the Issue model for populating the tags:
public static function tagAutoComplete($name = '') {
$sql = 'SELECT id ,tag AS label FROM tag WHERE tag LIKE :tag';
$name = $name . '%';
return Yii::app()->db->createCommand($sql)->queryAll(true, array(':tag' => $name));
actionTagAutoComplete in /controllers/IssueController:
// This function will echo a JSON object
// of this format:
// [{id:id, name: 'name'}]
function actionTagAutocomplete() {
$term = trim($_GET['term']);
if ($term != '') {
$tags = issue::tagAutoComplete($term);
echo CJSON::encode($tags);
Yii::app()->end();
}
}
EDIT
Widget in form:
<div class="row" id="checks" >
<?php
echo $form->labelEx($model, 'company',array('title'=>'File Company Distrubution; Companies can be edited by Admins'));
?>
<?php
$this->widget('application.extension.MultiComplete', array(
'model' => $model,
'attribute' => 'company',
'splitter' => ',',
'name' => 'company_autocomplete',
'sourceUrl' => $this->createUrl('becomEn/CompanyAutocomplete'),
'options' => array(
'minLength' => '1',
),
'htmlOptions' => array(
'style' => 'height:20px;',
'size' => '45',
),
));
echo $form->error($model, 'company');
?>
</div>
Update function:
$model = $this->loadModel($id);
.....
if (isset($_POST['News'])) {
$model->attributes = $_POST['News'];
$model->companies = $this->getRecordsFromAutocompleteString($_POST['News']
['company']);
......
......
getRecordsFromAutocompleteString():
public static cordsFromAutocompleteString($string) {
$string = trim($string);
$stringArray = explode(", ", $string);
$stringArray[count($stringArray) - 1] = str_replace(",", "", $stringArray[count($stringArray) - 1]);
$criteria = new CDbCriteria();
$criteria->select = 'id';
$criteria->condition = 'company =:company';
$companies = array();
foreach ($stringArray as $company) {
$criteria->params = array(':company' => $company);
$companies[] = Company::model()->find($criteria);
}
return $companies;
}
UPDATE
since the "value" porperty is not implemented properly in this extension I referred to extending this function to the model:
public function afterFind() {
//tag is the attribute used in form
$this->tag = $this->getAllTagNames();
parent::afterFind();
}
You should have a relation between Issue and Tags defined in both Issue and Tag models ( should be a many_many relation).
So in IssueController when you send the data to create or update the model Issue, you'll get the related tags (in my case I get a string like 'bug, problem, ...').
Then you need to parse this string in your controller, get the corresponding models and assigned them to the related tags.
Here's a generic example:
//In the controller's method where you add/update the record
$issue->tags = getRecordsFromAutocompleteString($_POST['autocompleteAttribute'], 'Tag', 'tag');
Here the method I'm calling:
//parse your string ang fetch the related models
public static function getRecordsFromAutocompleteString($string, $model, $field)
{
$string = trim($string);
$stringArray = explode(", ", $string);
$stringArray[count($stringArray) - 1] = str_replace(",", "", $stringArray[count($stringArray) - 1]);
return CActiveRecord::model($model)->findAllByAttributes(array($field => $stringArray));
}
So now your $issue->tags is an array containing all the related Tags object.
In your afterSave method you'll be able to do:
protected function afterSave() {
parent::afterSave();
//$issue_id = Yii::app()->db->getLastInsertID(); Don't need it, yii is already doing it
foreach ($this->tags as $tag) {
$sql = "INSERT INTO issue_tag_map (issue_id_fk, tag_id_fk)VALUES(:issue_id,:tag_id)";
$command = Yii::app()->db->createCommand($sql);
$command->bindValue(":issue_id", $this->id, PDO::PARAM_INT);
$command->bindValue(":tag_id", $tag->id, PDO::PARAM_INT);
$command->execute();
}
}
Now the above code is a basic solution. I encourage you to use activerecord-relation-behavior's extension to save the related model.
Using this extension you won't have to define anything in the afterSave method, you'll simply have to do:
$issue->tags = getRecordsFromAutocompleteString($_POST['autocompleteAttribute'], 'Tag', 'tag');
$issue->save(); // all the related models are saved by the extension, no afterSave defined!
Then you can optimize the script by fetching the id along with the tag in your autocomplete and store the selected id's in a Json array. This way you won't have to perform the sql query getRecordsFromAutocompleteString to obtain the ids. With the extension mentioned above you'll be able to do:
$issue->tags = CJSON::Decode($_POST['idTags']);//will obtain array(1, 13, ...)
$issue->save(); // all the related models are saved by the extension, the extension is handling both models and array for the relation!
Edit:
If you want to fill the autocomplete field you could define the following function:
public static function appendModelstoString($models, $fieldName)
{
$list = array();
foreach($models as $model)
{
$list[] = $model->$fieldName;
}
return implode(', ', $list);
}
You give the name of the field (in your case tag) and the list of related models and it will generate the appropriate string. Then you pass the string to the view and put it as the default value of your autocomplete field.
Answer to your edit:
In your controller you say that the companies of this model are the one that you added from the Autocomplete form:
$model->companies = $this->getRecordsFromAutocompleteString($_POST['News']
['company']);
So if the related company is not in the form it won't be saved as a related model.
You have 2 solutions:
Each time you put the already existing related model in you autocomplete field in the form before displaying it so they will be saved again as a related model and it won't disapear from the related models
$this->widget('application.extensions.multicomplete.MultiComplete', array(
'name' => 'people',
'value' => (isset($people))?$people:'',
'sourceUrl' => array('searchAutocompletePeople'),
));
In your controller before calling the getRecordsFromAutocompleteString you add the already existing models of the model.
$model->companies = array_merge(
$model->companies,
$this->getRecordsFromAutocompleteString($_POST['News']['company'])
);

Zend relationship - get the parent row

I know there are some examples in the web, but doesn't work in my case.
I have a Category table with subcategories. One table 'category' that has id_father that's the id of the Parent Category.
My configuration is the following:
Application_Model_DbTable_Category:
protected $_referenceMap = array(
'Application_Model_DbTable_Category' => array(
'columns' => 'id_father',
'refColumns' => 'id',
'refTableClass' => 'Application_Model_DbTable_Category'
));
CategoryMapper (I don't write the top code, anyway I retrieve a Category that has a parent in the db)
$row = $result->current();
echo $row->name;
$father = 'Non trovato';
$father = $row->findParentRow('Application_Model_DbTable_Category');
print_r($father);
This doesn't print anything... Is something wrong on my code? Thank you
you need to create instance of class Application_Model_DbTable_Category
$row = $result->current();
echo $row->name;
$father = 'Non trovato';
$father = $row->findParentRow(new Application_Model_DbTable_Category());
print_r($father);

Zend_Validate_Db_RecordExists against 2 fields

I usualy use Zend_Validate_Db_RecordExists to update or insert a record. This works fine with one field to check against. How to do it if you have two fields to check?
$validator = new Zend_Validate_Db_RecordExists(
array(
'table' => $this->_name,
'field' => 'id_sector,day_of_week'
)
);
if ($validator->isValid($fields_values['id_sector'],$fields_values['day_of_week'])){
//true
}
I tried it with an array and comma separated list, nothing works... Any help is welcome.

To do this you would have to extend the Zend_Validate_Db_RecordExists class.
It doesn't currently know how to check for the existence of more than one field.
You could just use two different validator instances to check the two fields separately. This is the only work around that I can see right now besides extending it.
If you choose to extend it then you'll have to find some way of passing in all the fields to the constructor ( array seems like a good choice ), and then you'll have to dig into the method that creates the sql query. In this method you'll have to loop over the array of fields that were passed in to the constructor.
You should look into using the exclude parameter. Something like this should do what you want:
$validator = new Zend_Validate_Db_RecordExists(
array(
'table' => $this->_name,
'field' => 'id_sector',
'exclude' => array(
'field' => 'day_of_week',
'value' => $fields_values['day_of_week']
)
);
The exclude field will effectively add to the automatically generated WHERE part to create something equivalent to this:
WHERE `id_sector` = $fields_values['id_sector'] AND `day_of_week` = $fields_values['day_of_week']
Its kind of a hack in that we're using it for the opposite of what it was intended, but its working for me similar to this (I'm using it with Db_NoRecordExists).
Source: Zend_Validate_Db_NoRecordExists example
Sorry for the late reply.
The best option that worked for me is this:
// create an instance of the Zend_Validate_Db_RecordExists class
// pass in the database table name and the first field (as usual)...
$validator = new Zend_Validate_Db_RecordExists(array(
'table' => 'tablename',
'field' => 'first_field'
));
// reset the where clause used by Zend_Validate_Db_RecordExists
$validator->getSelect()->reset('where');
// set again the first field and the second field.
// :value is a named parameter that will be substituted
// by the value passed to the isValid method
$validator->getSelect()->where('first_field = ?', $first_field);
$validator->getSelect()->where('second_field = :value', $second_field);
// add your new record exist based on 2 fields validator to your element.
$element = new Zend_Form_Element_Text('element');
$element->addValidator($validator);
// add the validated element to the form.
$form->addElement($element);
I hope that will help someone :)
Although, I would strongly recommend a neater solution which would be to extend the Zend_Validate_Db_RecordExists class with the above code.
Enjoy!!

$dbAdapter = Zend_Db_Table::getDefaultAdapter();
'validators' => array('EmailAddress', $obj= new Zend_Validate_Db_NoRecordExists(array('adapter'=>$dbAdapter,
'field'=>'email',
'table'=>'user',
'exclude'=>array('field'=>'email','value'=>$this->_options['email'], 'field'=>'is_deleted', 'value'=>'1')
))),
For those using Zend 2, If you want to check if user with given id and email exists in table users, It is possible this way.
First, you create the select object that will be use as parameter for the Zend\Validator\Db\RecordExists object
$select = new Zend\Db\Sql\Select();
$select->from('users')
->where->equalTo('id', $user_id)
->where->equalTo('email', $email);
Now, create RecordExists object and check the existence this way
$validator = new Zend\Validator\Db\RecordExists($select);
$validator->setAdapter($dbAdapter);
if ($validator->isValid($username)) {
echo 'This user is valid';
} else {
//get and display errors
$messages = $validator->getMessages();
foreach ($messages as $message) {
echo "$message\n";
}
}
This sample is from ZF2 official doc
You can use the 'exclude' in this parameter pass the second clause that you want to filter through.
$clause = 'table.field2 = value';
$validator = new Zend_Validate_Db_RecordExists(
array(
'table' => 'table',
'field' => 'field1',
'exclude' => $clause
)
);
if ($validator->isValid('value') {
true;
}
I am using zend framework v.3 and validation via InputFilter(), it uses same validation rules as zend framework 2.
In my case I need to check, if location exists in db (by 'id' field) and has needed company's id ('company_id' field).
I implemented it in next way:
$clause = new Operator('company_id', Operator::OP_EQ, $companyId);
$inputFilter->add([
'name' => 'location_id',
'required' => false,
'filters' => [
['name' => 'StringTrim'],
['name' => 'ToInt'],
],
'validators' => [
[
'name' => 'Int',
],
[
'name' => 'dbRecordExists',
'options' => [
'adapter' => $dbAdapterCore,
'table' => 'locations',
'field' => 'id',
'exclude' => $clause,
'messages' => [
'noRecordFound' => "Location does not exist.",
],
]
],
],
]);
In this case validation will pass, only if 'locations' table has item with columns id == $value and company_id == $companyId, like next:
select * from location where id = ? AND company_id = ?

How do I go around this Zend_Form_Element_Select db error?

When i use the Zend_Form_Element_Select elements with multioptions i get this error when i pass the selected value to Zend_DB_Table to insert into the db
Message: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'accounts_status ' in 'field list'
I have extracted some code snippets that i believe will go a long way into illustrating my problem.The accounts_status field DOES exist in my table
On my form construct have added the select element and options (I have left out the other elements)
$optionsstatus = array(
'active' => 'active',
'pending' => 'pending'
);
$optionsrole = array(
'guest' => 'guest',
'user' => 'user',
'writer' => 'writer',
'admin' => 'admin'
);
$status = new Zend_Form_Element_Select('accounts_status');
$status->setLabel('Status')
->setRequired(true)
->addMultiOptions($optionsstatus);
$role = new Zend_Form_Element_Select('accounts_role');
$role->setLabel('Role')
->setRequired(true)
->addMultiOptions($optionsrole);
I use the Zend_DB_table to insert the post values from my controller
public function addaccount($username, $fullname, $email,
$password,$status,$roles,$comments)
{
$data = array(
'accounts_username' => $username,
'accounts_fullname' => $fullname,
'accounts_email' => $email,
'accounts_password' => $password,
'accounts_status ' => $status,
'accounts_roles' => $roles,
'accounts_comments ' => $comments,
);
$this->insert($data);
}
In my controller i get the post values and send them to my model
$username = $form->getValue('accounts_username');
$fullname = $form->getValue('accounts_fullname');
$email = $form->getValue('accounts_email');
$password = $form->getValue('accounts_password');
$status = $form->getValue('accounts_status');
$roles = $form->getValue('accounts_roles');
$comments = $form->getValue('accounts_comments');
$accounts = new Model_DbTable_Account();
$accounts->addaccount($username, $fullname,$email,
$password,$status,$roles,$comments);
This approach works for me except when am dealing with the Zend_Form_Element_Select elements.Am just wondering if there is a specific way of dealing with this select elements when it comes to CRUD operations.
Message: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'accounts_status ' in 'field list'
Maybe I'm crazy, but looks to me like there's an extra space on that end of that 'accounts_status ' field name.
