Question

This is my current code:

$result = mysql_query("SELECT * FROM characters WHERE namn = 'Jargon'"); 

while($row = mysql_fetch_array($result)) 
  { 
  echo "<div class='content_left'>"; 
  echo "<div class='blue_text_header'>Information</div>"; 
  echo "<h1>"; 
  echo $row['Namn']; 
  echo "</h1>"; 

  echo "<br /><br /><br /><br /><br /><br /><br />"; 
  echo "<div class='red_text_header'>Obekräftade fall</div>"; 
  echo str_replace(',','<br />', $row['unconfirmed']); 

  echo "</div>"; 
  echo "<div class='content_right'>"; 

  echo "<div class='orange_text_header'>Andra namn</div>"; 
  echo str_replace(',','<br />', $row['Alias']); 

  echo "<br />"; 
  echo "<br /><br /><br /><br />"; 

  echo "<div class='green_text_header'>Bekräftade fall</div>"; 
  echo str_replace(',','<br />', $row['confirmed']); 
  } 

mysql_close($con);

and as you see, it is the “SELECT * FROM characters WHERE namn = 'Jargon'” that chooses what information to output and I want the users do decide what should be output, so I want like a simple search form, and if people write like “hello” I want the “Jargon” to be switched with hello, if u get it?

And if you can, can you make me both the search form and the post.php file?

Answer 1

Change your first line to these:

if (!isset($_GET['name']) { // Handle a missing name variable in some way 
    // (if you like you can even include the form on this page itself, allowing 
    //  the page to submit data back to itself, with this isset() check
    //  determining whether to show the form or process the form)
    print "You must enter a name";
    exit;
}
$result = mysql_query("SELECT * FROM characters WHERE namn = '".mysql_real_escape_string($name)."'");

…and add such a form:

<form action="post.php" method="get">
<label for="name">Name</label><input name="name" id="name"/>
<input type="submit"/>
</form>
