Yii search with criteria and add parameters - search

Question

I have one form and i want to search in my database. I create the object with all parameters but i have one problem. When write in one textfield search works fine and the query run correctly . When write two or more textfields params doesn't work and i have a fail execution of query :
WHERE
((((id_reservation=:id_reservation) AND (start=:start)) AND (end=:end)) AND
(fkCustomer.first_name=:first_name))
params doesn't replace.
$criteria=new CDbCriteria;
$criteria->with =array('fkCustomer');
if(!empty($start))
{
$criteria->addCondition('start=:start');
$criteria->params=array(':start'=>$start);
}
if(!empty($end))
{
$criteria->addCondition('end=:end');
$criteria->params=array(':end'=>$end);
}
if(!empty($merge->customer_name))
{
$criteria->addCondition('fkCustomer.first_name=:first_name');
$criteria->params=array(':first_name'=>$merge->customer_name);
}
if(!empty($merge->customer_surname))
{
$criteria->addCondition('fkCustomer.last_name=:last_name');
$criteria->params=array(':last_name'=>$merge->customer_surname);
}
if(!empty($merge->customer_email))
{
$criteria->addCondition('fkCustomer.email=:email');
$criteria->params=array(':email'=>$merge->customer_email);
}
$criteria->limit = 100;

Answer 1

It's because in every if block you replace the params array. Build an array in the if blocks then add it to $criteria->params on the last line, outside the blocks.
For instance:
$criteria=new CDbCriteria;
$criteria->with =array('fkCustomer');
$my_params = array();
if(!empty($end))
{
$criteria->addCondition('end=:end');
$my_params['end'] = $end;
}
if(!empty($merge->customer_name))
{
$criteria->addCondition('fkCustomer.first_name=:first_name');
$my_params['first_name'] = $merge->customer_name;
}
// other ifs ..
//then
$criteria->limit = 100;
$criteria->params = $my_params;
Also, if I remember correctly, you don't need to write ':end' and ':first_name' in the params array, it will work without the colon.

You also have the following alternative
$criteria=new CDbCriteria;
$criteria->with = 'fkCustomer';
if(!empty($end))
{
$criteria->compare('end', $end);
}
if(!empty($merge->customer_name))
{
$criteria->compare('fkCustomer.first_name', $merge->customer_name);
}
// The following conditions ..
// Limit:
$criteria->limit = 100;

Hi i think this is the same problem i have before with the params variable, for avoid this problem i use the CMap::mergeArray function
this happens because you overwrite the variable each time that the condition passed over it.
This is the syntax for avoid it, its an example
$criteria=new CDBCriteria;
$criteria->addBetweenCondition("Date",$datestart,$dateend);
$criteria->addCondition("Type=:type");
//$criteria->params=array(":type"=>"1"); //This is wrong, overwrites addBetweenCondition params
$criteria->params=CMap::mergeArray($criteria->params,array(
":type"=>"1",
)); //This is ok, mantain all parameters in the params var
$query=Model::findAll($criteria);

if(!empty($start))
{
$criteria->addCondition('start=:start');
$criteria->params['start']=$start;

{
$criteria->addCondition('end=:end');
$criteria->params['end']=$end;
}
if(!empty($merge->customer_name))
{
$criteria->addCondition('fkCustomer.first_name=:first_name');
$criteria->params['first_name']=$merge->customer_name;
}
if(!empty($merge->customer_surname))
