$_SESSION in <select> element

[helraizer1]

Hi all,

On my current project MyChatbox I have a box for which the user enters a name and the value of which is:

 
Name: <input type="textbox" name="username" onkeyup="countdown(username, 10, used)" maxlength="10" size="10" value="<?php echo $_SESSION['username']; ?>" /> 
 
 

So everytime they go to that page, or if the page refreshes; if they haven't closed the browser, the username they pick will stay in the box.

I also have a drop down list to pick a colour for the font.

The drop down is as follows:

            Select Text color:
              <select  name="color">
    <option value="black" >black</option>
    <option value="white" >white</option>
    <option value="blue">blue</option>
    <option value="red" >Red</option>
    <option value="yellow" >yellow</option>
    <option value="green">green</option>
  </select>
 

Is there a way that I could get it with the $_SESSION tag within the select element so that the same colour is selected on each session for the user?

Thanks,
Sam

Hi Sam.

You could add the color to the session the way you did with the username, and have PHP print out the options for the <select> box, adding the 'selected' property to the <option> tag you want selected.

Something like:

# Create array of options
$boxes = array();
$boxes[] = "blue";
$boxes[] = "green";
$boxes[] = "red";
 
# The selected box, this would be what you store in Session.
$selectedBox = "red";
 
# Loop through each box and print an <option> tag
foreach($boxes as $box) {
  if($box == $selectedBox) {
    # Selected box
    echo "<option selected=\"true\" value=\"$box\">$box</option>";
  }
  else {
    # Not selected
    echo "<option value=\"$box\">$box</option>";
  }
}
