Disable delete button if record exist in multiple table - php

Question

I have here mysql records display in html table with delete button. What I need to do is disable the delete button if record is exist in both database table.
How I can disable the delete button per row if record already exist in both table? any help will appreciate.
$search = $mysqli1->real_escape_string($_POST['bid']);
$search = preg_replace("/[^A-Za-z0-9 ]/", '', $search);
$search = $_POST['bid'];
$res = $mysqli1->query("select * from code WHERE item LIKE '%$search%' OR item_code LIKE '%$search%' OR cat_code LIKE '%$search%' order by item_code ASC");
while($r = $res->fetch_assoc()){
echo "<tr>
<td><a href='#' id='".$r['id']."' class='del'><img src='../images/del.png'></a></td>
</tr>";
}

Answer 1

throw in a simple if() statement
connected with the both queries
in pdo you use the ->rowCount()
not sure in mysqli
so this logic you'd need
query1 = counted rows in table1
query2 = counted rows in table2
as if you said if it exists in both tables it should hide it so you're going to work with an if-or statement
if(query1 == 0 || query2 == 0){
//show your button
}
what here stands is simple:
if(query1 equals 0 rows OR query2 equals 0 rows){
//show your button
}
//While you don't put up the else with something else it won't show anything
//so if there are the value of 1+ rows in both query1 and query2 this won't show anything
if you want me to provide a pdo example just reply
edit:
PDO Class to make it easier to connect
class Database extends PDO
{
private $db;
public function Database($host, $user, $pass, $db) {
try {
$this->db = new PDO("mysql:dbname=".$db.";host=".$host.";", $user, $pass);
} catch(PDOEXCEPTION $e) {
die('An error has occurred! [Code: '.$e->getCode().']! <br/>More info: ['.$e->getMessage().']!');
}
}
public function runQuery($query) {
try{
return $this->db->query($query);
} catch(PDOEXCEPTION $e) {
die('An error has occurred! [Code: '.$e->getCode().']!<br/>More info: ['.$e->getMessage().']!');
}
}
}
Now the row counting: updated there was a little mistake by the && and the 2x query1 check
$consite = new Database('DBHost','DBUsername','DBPassword','DBName');
$query1 = $consite->runQuery("SELECT * FROM TABLE1");
$query2 = $consite->runQuery("SELECT * FROM TABLE2");
if($query1->rowCount() == 0 || $query2->rowCount() == 0) {
//do your while statement to loop through it
//if you done your while statement it only shows the delete button
//for items that are NOT in both tables
}
sorry I was too lazy to add the while statement ;)
if I am correct you can check from multiple tables in a sql query so you can do it with 1 query if you make the multi check following 1 query!

Logical steps for this question:
1) Connect to the database
2) Make a query for table1
3) Count the entries(records) from table1
4) Make a query for table2
5) Count the entries(records) from table2
6) Check if one of them equals 0
7) if one of them equals 0 entries (records(rows)) then show the button
