    copied!<p>I have been trying to get this right, but it does not work. I can retrieve all the data from the database, but I wanted to retrieve a jobname from a html form which the user input in the form and a location also input in the form by the user and compare these texts with the jobname and location field on a table on the database. I know it sounds confusing, but here is my code that does nothing:</p> <pre><code>&lt;html&gt; &lt;body&gt; &lt;?php ob_start(); $host=""; // Host name $username= ""; // Mysql username $password=""; // Mysql password $db_name=""; // Database name $tbl_name=""; // Table name // Connect to server and select databse. mysql_connect("$host", "$username", "$password")or die("cannot connect"); mysql_select_db("$db_name")or die("cannot select DB"); // Define $myusername and $mypassword $job=$_POST['jobName']; $mylocation=$_POST['location']; // To protect MySQL injection (more detail about MySQL injection) $job = stripslashes($job); $mylocation = stripslashes($mylocation); $job = mysql_real_escape_string($job); $mylocation = mysql_real_escape_string($mylocation); $sql="SELECT * FROM ".$tbl_name." WHERE jobName='".$job."' and location='".$mylocation."';"; $result=mysql_query($sql); $num=mysql_numrows($result); mysql_close(); ?&gt; &lt;table border="0" cellspacing="2" cellpadding="2"&gt; &lt;tr&gt; &lt;td&gt;&lt;font face="Arial, Helvetica, sans-serif"&gt;jobName&lt;/font&gt;&lt;/td&gt; &lt;td&gt;&lt;font face="Arial, Helvetica, sans-serif"&gt;jobType&lt;/font&gt;&lt;/td&gt; &lt;td&gt;&lt;font face="Arial, Helvetica, sans-serif"&gt;Location&lt;/font&gt;&lt;/td&gt; &lt;td&gt;&lt;font face="Arial, Helvetica, sans-serif"&gt;Description&lt;/font&gt;&lt;/td&gt; &lt;td&gt;&lt;font face="Arial, Helvetica, sans-serif"&gt;Contact&lt;/font&gt;&lt;/td&gt; &lt;/tr&gt; &lt;?php $i=0; while ($i &lt; $num) { $job=mysql_result($result,$i,"jobName"); $type=mysql_result($result,$i,"jobType"); $myLocation=mysql_result($result,$i,"location"); $desc=mysql_result($result,$i,"description"); $cont=mysql_result($result,$i,"contact"); ?&gt; &lt;tr&gt; &lt;td&gt;&lt;font face="Arial, Helvetica, sans-serif"&gt;&lt;?php echo $job; ?&gt;&lt;/font&gt;&lt;/td&gt; &lt;td&gt;&lt;font face="Arial, Helvetica, sans-serif"&gt;&lt;?php echo $type; ?&gt;&lt;/font&gt;&lt;/td&gt; &lt;td&gt;&lt;font face="Arial, Helvetica, sans-serif"&gt;&lt;?php echo $myLocation; ?&gt;&lt;/font&gt;&lt;/td&gt; &lt;td&gt;&lt;font face="Arial, Helvetica, sans-serif"&gt;&lt;?php echo $desc; ?&gt;&lt;/font&gt;&lt;/td&gt; &lt;td&gt;&lt;font face="Arial, Helvetica, sans-serif"&gt;&lt;?php echo $cont; ?&gt;&lt;/font&gt;&lt;/td&gt; &lt;/tr&gt; &lt;?php $i++; } ob_end_flush(); ?&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>I just need a good tutorial to help me out although nothing I researched up to now helped me out, maybe if I can get an example code stating a similar issue, or a helping hand explaining where I am going wrong on this code. I appreciate it.</p>
