mysql database search by columns - php

Question

I'm new to mysql and php. I'm working on songs database. I have a search script which searches all columns of my database and it shows results in a table. But I want to make that search script to search by selected column field. Below the search box I want to add bullet options (ex: search by column 1, column 2, column 3, column 4) You can see a pic below.
Songs database table.
+----+--------+----------+-----+-------+
| id | title | artist | key | genre |
+----+--------+----------+-----+-------+
| 1 | xxxxx | xxx xxxxx| xxx | xxxxx |
| 2 | xxxxx | xxx xxxxx| xxx | xxxxx |
| 3 | xxxxx | xxx xxxxx| xxx | xxxxx |
| 4 | xxxxx | xxx xxxxx| xxx | xxxxx |
| 5 | xxxxx | xxx xxxxx| xxx | xxxxx |
+----+--------+----------+-----+-------+
Search script :
<?php
$host = "localhost";
$user = "xxxxxxx";
$password = "xxxxxxx";
$database_name = "xxxxxx";
$pdo = new PDO("mysql:host=$host;dbname=$database_name", $user, $password, array(
PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION
));
$pdo->exec("set names utf8");
$search=$_POST['search'];
$query = $pdo->prepare("select * from table where title LIKE '%$search%' OR key LIKE '%$search%' OR genre LIKE '%$search%' OR artist LIKE '%$search%' LIMIT 0 , 100");
$query->bindValue(1, "%$search%", PDO::PARAM_STR);
$query->execute();
if (!$query->rowCount() == 0) {
$row_cnt = $result->num_rows;
printf("<p class='notice'>Your search for <span class='blue'>“</span><span class='blue'>" . $result['search'] . "</span><span class='blue'>”</span> yielded %d results.\n</p>", $row_cnt);
echo "<table class='table'>";
echo "<tr class='tablehead'>";
echo "<th>Title</th>";
echo "<th>Artist</th>";
echo "<th>Key</th>";
echo "<th>Genre</th>";
echo "</tr>";
while ($results = $query->fetch()) {
echo "<tr>";
echo "<td> " " " . $results['title'] . " </td>";
echo "<td>" . $results['artist'] . "</td>";
echo "<td>" . $results['key'] . "</td>";
echo "<td>" . $results['genre'] . "</td>";
echo "</tr>";
}
echo "</table>";
} else {
echo 'Nothing found';
}
?>

Answer 1

You should get values of your radio buttons and make appropriate query
$search=$_POST['search'];
$field=$_POST['radio_grp'];
switch($field)
{
case 'Title' : $filed='title' // or your column field
break;
//---similar cases
}
$query = $pdo->prepare("select * from table where $field LIKE '%$search%' LIMIT 0 , 100");

Answer 2

Try this code
Set the value of radio button same as column name
<input type="radio" name="search_by" value="title">title<br>
<input type="radio" name="search_by" value="artist">artist<br>
<input type="radio" name="search_by" value="key">key<br>
<input type="radio" name="search_by" value="genre">genre<br>
$search=$_POST['search'];
$search_by=$_POST['search_by'];
$query = $pdo->prepare("select * from table where $search_by LIKE '%$search%' LIMIT 0 , 100");
