i have two tables pages and page_desc and have a relation
$this->hasMany('Model_PagesDesc as PageDesc', array(
'local' => 'id',
'foreign' => 'pages_id'));
i have a query
return Doctrine_Query::create()
->select('m.*, d.*')
->from('Model_Pages m')
->leftJoin('m.PageDesc d')
->execute();
NOW WHEN QUERY EXECUTES. iN VIEW WHEN I TRY TO GET FIELD VALUE OF SCEOND TABLE IT RETURNS SOME INTEGER INSTEAD OF ACUAL VALUE IN FIELD
<?php echo $pages->PageDesc->content;?>
If youre using hasMany then you should Model_Pages::PagesDesc will be a Doctrine_Collection not a Model_PagesDesc instance. Im not sure but i would assume that the default behavior of the collection is to return the count of elements in the collection when converted to string, thus the integer. You need to either loop over the collection or get a specific item.
<?php echo $pages->PageDesc->getFirst()->content; ?>
OR
<?php foreach($pages->PageDesc as $desc): ?>
<?php echo $desc->content; ?>
<?php endforeach; ?>
Or you could write a custom collection for this model that returns concat of the content fields for every element in the collection.
However it seemdsthat a page shouldnt really have more than one description should it? You might want to consider using a 1-1 relation or just making the description a column on your page model.

Suppose to have an entity in Symfony2 that has a field bestfriend, which is a User entity selected from a list of User entities that satisfy a complex requirement.
You can render this field in a form by specifying that it is an entity field type, i.e.:
$builder->add('bestfriend', 'entity', array(
'class' => 'AcmeHelloBundle:User',
'property' => 'username',
));
This form field is rendered as a <select>, where each one of the displayed values is in the form:
<option value="user_id">user_username</option>
So, one would render the field by using the <optgroup> tags to highlight such special feature of the friends.
Following this principle, I created a field type, namely FriendType, that creates the array of choices as in this answer, which is rendered as follows:
$builder->add('bestfriend', new FriendType(...));
The FriendType class creates a <select> organized with the same <option>s but organized under <optgroup>s.
Here I come to the problem! When submitting the form, the framework recognize that the user field is not an instance of User, but it is an integer. How can I let Symfony2 understand that the passed int is the id of an entity of type User?
Here follows my solution.
Notice that it is not mentioned in the Symfony2 official docs, but it works! I exploited the fact that the entity field type is child of choice.
Hence, you can just pass the array of choices as a param.
$builder->add('bestfriend', 'entity', array(
'class' => 'AcmeHelloBundle:User',
'choices' => $this->getArrayOfEntities()
));
where the function getArrayOfEntities() is a function that fills the choice list with the friends of my friends, organized by my friends:
private function getArrayOfEntities(){
$repo = $this->em->getRepository('AcmeHelloBundle:User');
$friends = $repo->findAllFriendByComplexCriteria(...);
$list = array();
foreach($friends as $friend){
$name = $friend->getUsername();
if(count($friend->getFriends())>0){
$list[$name] = array();
foreach($friend->getFriends() as $ff){
$list[$name][$ff->getUsername()] = $ff;
}
}
}
return $list;
}
I know the example could be meaningless, but it works...
PS: You need to pass the entity manager to let it working...
In zend project I fetch data from the database and show in a table. It shows data in the same order as stored in the database. But I want to show the fileds in diffeent order than in database order. But I don't know how to do thid. Here I means field order not the row order.
Please help me in this regard.
Thanks
Its hard to say how youre displaying but lets assume you have made Table Classes for each table i would do something like this:
<?php foreach $zendDbRowObject->getTable()->getDisplayOrder() as $fieldName): ?>
<?php echo $zendDbRowObject->$fieldName; ?>
<?php endforeach; ?>
So then in your Table clas for a particular table you can create a property/method to get the fields in the order you want them in:
public function getDisplayOrder() {
// fake column names obviously... use yours here.
return array(
'column5',
'column1',
'column4',
'column2',
'column3'
);
}
when you do db select, you can select the coloumns that you want, so instead of select *,
you do select col5,col3,col2,col6,col1 from tablename
This will change the order of the columns
$select = $db->select()
->from(array('t' => 'table'),
array('t.col2', 'p.col1`'));
So in an Index view for a certain model, I'm including some checkboxes; I have an array of days of the week, and so have 7 checkboxes available, per record.
I can save data, no problem. What I can't figure out is how to pre-select the checkboxes, based on each record's saved data. Currently I'm having to do this:
<?php if ( isset($user['SurveyAssignment'][0]['active_days']['Monday']) && $user['SurveyAssignment'][0]['active_days']['Monday'] == 1 ) { $monChecked = true; } else { $monChecked = false; } ?>
<?php echo $this->Form->input('SurveyAssignment.' . $count .'.active_days.Monday', array('type' => 'checkbox', 'label' => false, 'div' => false, 'checked' => $monChecked));?>
And that's just for ONE day, for one record. Right now, I'm doing that 7 times, for each record. It's very bloated.
I would have thought I could just read in the array for each record, and select a group of checkboxes accordingly.
I'm sure I'm missing something very simple but I can't see past my nose at the moment.
If your associations are set up correctly, your field name is correct, and you're passing the correct data, they will be selected automatically for you.
The likely answer is you're not using the correct field or Model.field for your form input.
I have few fields on the form like name, description, timestamp.
Now in the form I am only displaying name and description but not timestamp.
public function __construct()
{
$this->setTimestamp(new \DateTime());
}
Now in my database, it is coming as null.
Either doctrine is not executing constructor or those fields are set to null when displayed in form.
Even though I am not displaying them.
You need put the timestamp field in your FormType.
If you don't need to show it, just hide the field and set default value.
Something like that:
$builder->add('timestamp', 'hidden', array(
'data' => new \DateTime(),
));
Don't forget {{form_rest(form)}} at end of the twig template to send all hidden fields.
I'm writing this question cause I have difficulties setting up default values for a _MultiCheckbox element of a Zend Framework 1.9.3.
I create Zend_Form_Element_MultiCheckbox with multiple options like this:
$multiCheckbox = new Zend_Form_Element_MultiCheckbox( 'elId',
array ( 'disableLoadDefaultDecorators' =>true ) );
$multiCheckbox ->setName( 'elId' )
->setLabel('elId')
->setRequired( false )
->setAttrib('class', 'inputtext')
->setDecorators( array( 'ViewHelper' ) )
->setMultiOptions( $options );
where the $options array is an associative array 'key' => 'value'. The field is displayed just fine and I can get all the checked values for that element.
When returning to that page I need to restore from the DB the whole list of options again and mark the checked ones. I have tried to do it like that:
$multiCheckbox ->setValue( $defaults );
where $default is array, containing elements of type 'checked_option_field_id' => true(eg. array( '1222' => true, '1443' => true ) ). That action checks ALL the checkboxes and not only the once I need and I have passed to the setValue() method.
I have tried to pass just an array containing elements of type 'checked_option_field_id', (eg. array( '1222', '1443' ) )but that also doesn't work - NONE of the checkboxes is checked.
I have used the form setDefaults() method with those two kinds of arrays, but the results are same - as this method uses again setValue() for each element.
MultiCheckbox element is rendered like that ( result when try to set checked value for only one option ):
<label for="elId-1222"><input type="checkbox" name="elId[]" id="elId-1222" value="1222" checked="checked" class="inputtext">BoRoom </label><br />
<label for="elId-1443"><input type="checkbox" name="elId[]" id="elId-1443" value="1443" checked="checked" class="inputtext">BoRoom Eng2 </label><br/>
That element populates the checked option values in the elId[] array. That is the element name.
setDefaults() form method gets all form elements by name and commit their default values by calling setDefault() form method and after that setValue() element method. So my multicheckbox element has name elId ( it does not get all the element options one by one ) and set default values for all options instead of just the given in the array.
That is how I see it and I can't find solution how to set default values only for some of the options of a multicheckbox element.
Chris is correct that setValue() expects an array of values to be 'checked' (not an array of bool values keyed by your option IDs).
If you are looking for the logic behind the form generation, don't look at the Zend_Form_Element object (or the many extended elements from it), look at the Zend_View_Helper objects. Specifically the Zend_View_Helper_FormRadio object.
When generating the HTML the options array is looped, then the value is checked against the value array - the array passed to setValue(), using in_array().
From Zend_View_Helper_FormRadio line: 150
// is it checked?
$checked = '';
if (in_array($opt_value, $value)) {
$checked = ' checked="checked"';
}
Not sure what that's not working for you, but if you're passing:
$element->setMultiOptions(array('1111' => 'Some Label',
'2222' 'Some Other Label',
'3333', 'Not Selected Label'));
$element->setValue(array('1111','2222');
It should work. Maybe if you could include some code it would be easier to see what's going on?
The setValue() expects a array with those values that need to be checked, in this case for example you need to pass a array with values 1222, 1443 for them to be marked as checked.
You need to serialize the checkbox value before insert in database. To show the database value selected again you have to unserialize the data to show.
