[SOLVED] problem with option tags

[ekante]

Where is problem, why doesnt it assign anything to $status ?

 

<?php

echo '		<tr>
		<td width=\"150\" align=\"right\">Tava karjera :</td>
			<td><select name=\"Chose\">
				<option value=\"$select_waiting\">Simple User</option>
				<option value=\"$select_pilot\">Pilot</option>
				<option value=\"$select_manager\">Manager</option>
			</select>* $user_taken_err</td>
	</tr>';

			if (isset($select_waiting)) {
				$status = "waiting";
			}
			if (isset($select_manager)) {
				$status = "manager";
			}
			if (isset($select_pilot)) {
				$status = "pilot";
			}
?>

Because you're not posting anything?

Also, you're variables are being echoed within single quotes so they will not expand.

You don't quite understand how PHP works and separation of Server Side and Client Side code.

 

HTML is Client Side code. Basically, your webserver passes a text file with a bunch of HTML tags and text in it to the client's browser. The client's browser then interprets this text file and renders it as a webpage.

 

PHP is Server Side code. It it used to make the text file that is sent to the client's browser more dynamic.

 

So, all the steps that happen are as follows:

-Client requests webpage

-Server receives request and gets file being requested

-Server sends the file through the PHP parser

-Server sends render text file to client

-Client receives text file

-Client parses HTML and renders the webpage

 

Now, if you want to send data from the client back to the server, you need to make another request and pass the data with it (usually in the form of a form). Here is a basic example of a form post:

<?php
  if($_SERVER['REQUEST_METHOD'] == 'POST'){
    print "You selected ".$_POST['fruit'];
    exit;
  }
?>
<form method="post" action="">
  <select name="fruit">
    <option>Apple</option>
    <option>Orange</option>
    <option>Banana</option>
  </select>
  <input type="submit" value="Submit" />
</form>
