Question

I’ve built this little script that searches a table in my database, but for the life of me I can’t seem to find anywhere on how to display the table information if someone only searches for the email. I want to be able to search for only the email and have it display all the information for that email address from the database. Any thoughts?

<?php
$profile = $_POST["profile"];

mysql_connect ("", "", "");
mysql_select_db ("");

$query = "SELECT * FROM `profile` WHERE `email`='$email' and `about`='$about' and 
`age`='$age' and `sex`='$sex' and `website`='$website'";


$result = mysql_query ($query);
if ($result) {
while($row=mysql_fetch_row($result))
{
echo $row[0],$row[1],$row[2];
}
}else{

}
?>

<form action="profile.php" method="post">
<input type="text" name="search"><br>
<input type="submit">

Non-numeric field must be enclosed with single quotes in a query.

<?php  

  $search = $_POST["search"];
  mysql_connect("localhost", "username", "password") OR die (mysql_error());
  mysql_select_db ("your_db_name") or die(mysql_error());

  $query = "SELECT * FROM `profile` WHERE `email`='$search'";

  $result = mysql_query($query) or die (mysql_error());

  if($result) 
   {    
      while($row=mysql_fetch_row($result))   
       {      
          echo $row[0],$row[1],$row[2];   
       }    
     }
   else
     { 
       echo "No result";  
     }
 ?>

<form action="profile.php" method="post">  
  <input type="text" name="search"><br>  
  <input type="submit">
</form>   

EDIT:

In above code-snippet you have single text field and a submit button so you can use "search" field value to search on any one database field at a time.

If you want to search on email then sql query will be:

SELECT * FROM `profile` WHERE `email`='$search'";

You can use OR operator to search on one or more field:

 SELECT * FROM `profile` WHERE `email`='$search' or about`='$search'";

You can use LIKE operator to search a string

SELECT * FROM `profile` WHERE `email` LIKE '%$search%'";
