Mysql query issue
<p>My database table (<strong>Name:Wall</strong>) structure is bellow:</p>

<pre><code>-----------------------------------------------------
id(type = int)    like(type = int)       wall_id(type =int)           
-----------------------------------------------------
1                 0                        1
2                 0                        2
-----------------------------------------------------   
</code></pre>

<p>In wall.php file there are a text button name "<strong>Like this</strong>". So is there any way send a query to Mysql database after click on this text(<strong>Like this</strong>).</p>

<p>Actually i want to create a like system. If anyone like user wall post then he/she can click on this text (<strong>Like this</strong>) to like  user wall. So after every click, mysql database <strong>like</strong> field value should be increase by 1.</p>

<p>Normally I can send a query to datbase with:</p>

<pre><code>$sql = mysql_query("INSERT INTO wall VALUES('', '1')");   
</code></pre>

<p>Can anyone give me solution :-)</p>
