PHP Searching with first and last name - php

Question

my project partner and I are relatively new to PHP and needed some help in searching through multiple columns. We are trying to have a functioning search bar that returns the name and corresponding youtube url of a comedian depending on the first and last name that was searched. We got it to work with first name OR last name being searched but not with both of them. (i.e Sarah or Silverman will work but not Sarah Silverman) We tried changing the clause to AND but that did not work at all. Below is our search code.
The line
$searchdb = mysqli_query($con,"SELECT *
FROM comedian
WHERE fname LIKE '%$searchq%'
OR lname LIKE '%$searchq%'")
or die ("Could not search.");
is what we are trying to modify.Thank you!
<?php
session_start();
$con = mysqli_connect('localhost','root','') or die("Could not connect");
mysqli_select_db($con, 'youtube') or die(mysqli_error($con));
$output = '';
if(isset($_POST['search'])){
$searchq = $_POST['search'];
//Will replace everything that is not a letter or number with blank.
$searchq = preg_replace("#[^0-9a-z]#i","",$searchq);
$searchdb = mysqli_query($con,"SELECT *
FROM comedian
WHERE fname LIKE '%$searchq%'
OR lname LIKE '%$searchq%'")
or die ("Could not search.");
$count = mysqli_num_rows($searchdb);
if($count == 0){
$output = 'There were no search results.';
print("$output");
}else{
while($row = mysqli_fetch_array($searchdb)){
//Variables
$fname = $row['fname'];
$lname = $row['lname'];
$comedianid = $row['comedianid'];
//Output first and last name
$output .= '<div> <b>Comedian:</b> '.$fname.' '.$lname.'</div>';
//Matching comedian with respective video URL using about table relation.
$searchdb2 = mysqli_query($con,"SELECT * FROM about WHERE comedianid LIKE '%$comedianid%'") or die ("Could not find a video by this author.");
//Fetches comedian id from about table
$row2 = mysqli_fetch_array($searchdb2);
$url = $row2['url'];
$outputvid = preg_replace("#.*youtube\.com/watch\?v=#","",$url);
$outputvid = '<iframe width="700" height="600" src="https://www.youtube.com/embed/'.$outputvid.'"></iframe>';
print("$output");
print("$outputvid");
$output = '';
}
}
}

Answer 1

You can concatenate the first and last name and then search based on that string...
SELECT *
FROM comedian
WHERE fname || ' ' || lname LIKE '%Sarah Silverman%'
This will show "Sarah Silverman", even though Sarah is stored in fname and Silverman in lname
Edit: I have tested it in SQLite, you might have to change || to + based on your database management system.
