select form box remember data!

okay I can't figure out how to do this (I guess that's obvious eh). well i have some forms which a user enters info, it is put into the database, and then the user can go back and edit it. But some of it is in select boxes (like birthdate). Now I can't figure out how to make the value in the database be put into the box, and this is especially annoying if a user wants to edit some things but not the drop box, it makes the drop box whatever is teh normal first value. for the birthday I did this:

this is just for year

PHP Code:


		
			
<select name="strYear">

        <?php if($IsLoggedIn)

                { ?>

        <option Selected><?php echo $year; ?></option>

        <?php } else { ?>        

          <option>Year</option>

          <?php } ?>

          <option>-----</option>

          <?php 

      $yearValue = 1980;

      while($yearValue <= 2003)

      {

      $yearValue = $yearValue + 1;?>

          <option><?php echo $yearValue; ?></option>

          <?php } ?>

        </select>

this basically jsut makes the top value the value they entered... can i get it to jsut center in on that value in my normal list? is there a better way to do this?
thanks

Try this:

PHP Code:


		
			
<select name="strYear">

<?php

for($i=1980; $i< date('Y'); $i++){

    $selected=(($i==$year)?" selected":"");

    print "<option value=\"" . $i . "\"" . $selected . ">" . $i . "</option>\n";

}

?>

</select>

thank you! that works really well! I was wondering, in the case of text and not numbers, how would it be done? such as my month, it is sort of a long part of my script. I was wondering maybe you could even just comment that other code, so I could see exactly what it all does, cause I'm still pretty new. Thank you. And be expecting a pm! haha

PHP Code:


		
			
<select name="strYear">

<?php

//Here I'm using the current date rather than hard-coding it as you had. 

//Reduces maintenance issues down the road b/c you won't have to remember to edit the year each new year.



for($i=1980; $i< date('Y'); $i++){

    //Ternary operator here:

    //Evaluates $i==$year

        //If true, return part after ?

        //Else return the part after the colon

        //This is just a shorthand way of doing an if-else statement.

        //Basically, if the values match, we're returning the string " selected" and inserting it into the option tag. Else we're inserting nothing.

    $selected=(($i==$year)?" selected":"");

    print "<option value=\"" . $i . "\"" . $selected . ">" . $i . "</option>\n";

}

?>

</select>

You should be able to use the code with text or numbers. If you're using text, you'd want to create an array of possible text values and pass that to the for statement like so:

PHP Code:


		
			
<?php



for($i=0; $i<sizeof($textarray); $i++){

    $selected=(($textarray[$i]==$databasevalue)?" selected":"");

    print "<option value=\"" . $textarray[$i] . "\"" . $selected . ">" . $textarray[$i] . "</option>\n";

}



?>
