Sql Query Result based on Condition - php

Question

I have two put two condition in the result of a sql query result for the below function:
Table projects has two columns a_name and b_name and I want to exclude result in which b_name has value = xxxxx and value in a_name and b_name are same.
Below is currently used:
public function search_project_name($term)
{
$params = array( ':term' => $term);
$sql = "SELECT * FROM projects WHERE project_name like '%$term%'ORDER BY projects.create_date DESC $limit";
$stmt = parent::query($sql, $params);
while($row = $stmt->fetch(PDO::FETCH_ASSOC)) :
$result[]=$row;
endwhile;
return $result;
}

Answer 1

You could add these condition with a not operator:
SELECT *
FROM projects
WHERE a_name like '%$term%' AND
NOT (a_name = 'xxxx' and a_name = b_name)

Answer 2

Problem part is $term in query so replace $term with :term try updated code:
public function search_project_name($term){
$params = array(
':term'=>$term);
$sql = "SELECT * FROM projects WHERE project_name like '%:term%'ORDER BY projects.create_date DESC $limit";
$stmt = parent::query($sql, $params);
while($row = $stmt->fetch(PDO::FETCH_ASSOC)) :
$result[] = $row;
endwhile;
return $result;
}
One more missing parameter is $limit you used in query but not passed to function?
With $limit as 2nd parameter default set to 10 rows:
public function search_project_name($term, $limit = 10){
$params = array(
':term'=>$term);
$sql = "SELECT * FROM projects WHERE project_name like '%:term%'ORDER BY projects.create_date DESC $limit";
$stmt = parent::query($sql, $params);
while($row = $stmt->fetch(PDO::FETCH_ASSOC)) :
$result[] = $row;
endwhile;
return $result;
}
