Multi word search on multiple columns Symfony Doctrine - php

Question

I am trying to craft a multiword search that will query multiple columns in a table. My code works great thus far for a single column, but as you can imagine using it for more then one column becomes an issue.
If I add orWhere it won't work, and I don't really want to create more for loops because it will become quite cumbersome. Any Ideas?
$query = $request->getParameter("article-search");
$keywords = explode(" ", $query);
for( $i = 1; $i <= count( $keywords ); $i++ ){
$q->addWhere("a.title LIKE ?", "%" . $keywords[$i - 1] . "%");
}

Answer 1

I just did it like this.. Maybe it helps somebody..
$now = "some other parameter";
$parts = explode(" ",trim($searchtext));
$clauses=array();
// static paramtter setted here
$parameters = array(
':now' => $now
);
$i = 0;
foreach ($parts as $part){
// for every word make new search query and parameter
$parameters[":param".$i] = "%".$part."%";
if($i == 0){
$clauses = "v.description LIKE :param".$i." OR v.name LIKE :param".$i." OR v.sale LIKE :param".$i;
} else {
$clauses .= " OR v.description LIKE :param".$i." OR v.name LIKE :param".$i." OR v.sale LIKE :param".$i;
}
$i ++;
}
$qb->select('v')
->from('MyBundle\Entity\Voucher', 'v')
->where('v.date_start <= :now')
->andWhere('v.date_end >= :now')
->andWhere($clauses)
->setParameters($parameters);

Usually I would write this as a query that looks something like the following:
$query = "`where column like '%$keywordOne%' or column like '%keywordTwo%'`";
Though I'm not sure how you implement that with the query-building tool you have there.
Here's a quick example that might help build the where portion of the query using the array of keywords you have:
<?php
$keywords = array("bing", "bang", "jump");
$query_start = 'where colummName';
$like_portion = "like '%" . implode("%' or columnName like '%", $keywords) . "%'";
if(sizeof($keywords) > 0) {
echo "`$query_start $like_portion`";
} else {
// No keywords
}
?>
Let me know if there's anything I can clarify here

Maybe you can consider using "union"? Also, for such complex queries, I would use native SQL instead of ORM practice.
