  2. Hello, Mr. Smith.
    You can explain very clear php possibilities. Your example works with me very stable with a few moderations. Can you explain how to grab data from table generated after search and use it for example to insert in another table?

  9. <?php

    mysql_connect("localhost","root" ,"admin")or die ("could not connect");
    mysql_select_db("sentmentanalysis" )or die ("could not find db");
    $output= '' ;

    if(isset($_POST['seach'])){
    $searchq = $_POST['seach'];
    $searchq = preg_replace("#[^0-9a-z]#i","",$searchq);
    $query = mysql_query("SELECT * FROM post WHERE Title LIKE '%$$searchq%'OR Contect LIKE '%$searchq%'") or die ("could not search");
    $count = mysql_affected_rows($query);
    if ($count ==0){
    $output = 'There was no search results' ;
    }else{
    while ($row = mysql_fetch_array($query)){
    $titel = $row['Title'];
    $contect = $row['Contect'];
    $output = '<div>'.$titel.' '.$contect.'</div>';
    }
    }
    }
    ?>

  21. Hey. When I load the page, it gives me this error: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '%% OR last_name LIKE '%%'' at line 1

  29. How do you display multiple records with the same name ? I mean I've tried also your way but I still it doesn't display multiple results. Maybe because of some coding in java which is included in my code?
