i am doing

1. i am getting the value form the url my url looks like localhost\demo\article.php?filter=computer

   $_GET['filter']

2. my database is

   id | name |tag
   
   1  |java  |a:2:{i:0;s:8:"Computer";i:1;s:4:"Code"; 
   
   2  |dbms  |a:2:{i:0;s:8:"Computer";i:1;s:4:"dbms";

for that i am using the query

$query1 = "SELECT * FROM $tableName WHERE tag='%".$_GET['filter']."%' ";

but its not showing the row having the computer or code..

its like the stackoverflow tag filtration

Answer 1

Solving your problem is by replacing = with like so your query should be

$query1 = "SELECT * FROM $tableName WHERE tag like '%".$_GET['filter']."%' ";

a better way of doing this, is to create extra two tables. One will contain your tags (optional) and the other will contain tagging information.
