Data retrieval and display in Symfony - php

Question

I am new to Symfony, I have a table users with two columns: user_name and first_name, I want to display all users whose names (user_name & first_name) contains $search:
<?php
namespace Login\LoginBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;
use Login\LoginBundle\Entity\Users;
use Login\LoginBundle\Modals\Login;
use Doctrine\DBAL\DriverManager;
public function homeAction(Request $request) {
$session = $this->getRequest()->getSession();
if ($request->getMethod() == 'POST') {
$search_for = $request->get('search');
//what to write here --save my life guys
}
return $this->render('LoginLoginBundle:Default:home.html.twig');
}

It's like a full process of querying and fetching data, passing the results to the template. What you need to do is following below steps:
1) Get the repository of your entity (table) and call your custom search function which is created in the repository (of course you can merge this step and next one to have all in your controller homeAction function) I assume your entity name is Users
public function homeAction(Request $request) {
$session = $this->getRequest()->getSession();
$results = array();
if ($request->getMethod() == 'POST') {
$search_for = $request->get('search');
$em = $this->getDoctrine()->getManager();
$results = $em->getRepository('LoginLoginBundle:Users')->searchPhrase($search_for);
}
return $this->render('LoginLoginBundle:Default:home.html.twig', array(
'results' => $results
));
}
2) Now you need to build a repository class for you entity and implement below function in it Entity Repository in Symfony (or merge the code below to your controller)
public function searchPhrase($phrase) {
$query = $this->createQueryBuilder('U');
$result = $query->where(
$query->expr()->like('U.username', $query->expr()->literal("%$phrase%"))
)
->andWhere(
$query->expr()->like('U.firstName', $query->expr()->literal("%$phrase%"))
)
->getQuery()
->getResult();
return $results;
}
Keep in mind because you mention "AND" I used andWhere whereas you can use orWhere; because you said "CONTAIN" I used like expression with % and that's the way you can create expression in DQL Here is a full list of Doctrine2 expressions
3) last step is to show the results in your twig template; I assume you want to show them in table rows
<table>
<tr>
<th>Username</th><th>First Name</th>
</tr>
{% if results|length > 0%}
{% for item in results %}
<tr>
<td>{{ item.getUsername }}</td><td>{{ item.getFirstName }}</td>
</tr>
{% endfor %}
{% else %}
<tr>
<td colspan="2">No matching results found!</td>
</tr>
{% endif %}
</table>
Hopefully this helps

Thank you guys, But I this worked for me:
$repository = $this->getDoctrine()->getRepository('LoginLoginBundle:Users');
$query = $repository->createQueryBuilder('u')
->where("u.userName LIKE '%".$search_for."%' or u.firstName LIKE '%".$search_for."%'")
->getQuery();
$Myusers = $query->getResult();
if ($Myusers) //test if there are results returned
{
foreach ($Myusers as $user)
{
echo "E-mail : ".$user->getUserName()." -- Name : ". $user->getFirstName()."<br>";
}
}
else
{
echo "No matching results found!!";
}
//end-display
