Fatal error: Uncaught Error: Call to a member function select() on null.Magento2
Question
<?php
$connection = $this->getConnection();
$select = $connection->select();
$select = $model->getCollection()
->select()
->count()
->from($this->getDbPrefix() . 'name_table', '*')
->where('result', ' likes%');
return (int)$objectManager->fetchOne($select);
?>
I want SELECT COUNT (*) FROM name_table WHERE result LIKE 'likes%' to be executed, and a numeric value is displayed on the page.How do I do it? I'm a beginner. I'll be very grateful for your help!
Solution
Your code wrong on two cases.
If $model
a model class then $model->getCollection()->select()
have to chanages $model->getCollection()->getSelect()
. athat is wrong.
Also, (int)$objectManager->fetchOne($select)
wrong.
You can use collection
$model->getCollection()->addAttributeToFilter('result', ['like' => 'likes%']);
OTHER TIPS
Try below code
$collection->addAttributeToFilter('name', array(
array('like' => '% '.$needle.' %'), //spaces on each side
array('like' => '% '.$needle), //space before and ends with $needle
array('like' => $needle.' %') // starts with needle and space after
));
Passing the second parameter as an array of arrays will concatenate the conditions using OR
I hope it helps!
