This is a shortcut for adding a text search for multiple values i.e.
... WHERE [other conditions here] AND (name LIKE '%ABC%' OR name LIKE '%RET%' OR name LIKE '%Anything else%') ...
For a scenario where only the name field above is the only condition a single CDbCriteria instance will do i.e
$c1=new CDbCriteria; foreach($search_values as $txt){ $c1->compare('name',$txt,true,'OR'); }
The problem is this will produce the following sql when searching with say a 'type' field too:
... WHERE ((((type=1) OR (name LIKE '%ABC%')) OR (name LIKE '%RET%')) OR (name LIKE '%Anything else%')) ...
One solution is to ensure that your condition for the search on name appears first such that the sql produced will read
... WHERE ((((name LIKE '%ABC%') OR (name LIKE '%RET%')) OR (name LIKE '%Anything else%')) AND (type=1)) ...
For cases where this isn't possible, the solution is to create another CDbCriteria instance to handle this specific condition and use CDbCriteria::addCondition() to add it to the original criteria as follows.
$c1=new CDbCriteria; // original criteria $c2=new CDbCriteria; // criteria for handling our search values foreach($search_values as $txt){ $c2->compare('name',$txt,true,'OR'); } $c1->addCondition($c2->condition); $c1->params+=$c2->params; // Add the params for $c2 into $c1
