Select Menu and if else statments

[LongWei]

Hi all,


i got small select menu with codes that goes

 <select name="size" id="size" size ="2">
              <option value="a">Less than 1 Megabyte</option>
              <option value="b">&gt;1 Mb &lt; 10Mb</option>
              <option value="c">More than 10 Megabyte</option>
            </select>

However everytime when the form is click the option value is 'a' instead of 'b' regardless of option i select

if(isset($_POST['size']) && isset($_POST['criteria']) )
{

$size = $_POST['size'];

    if ($size = 'b') {$sizeq = "image_size < 1000000";}
	else if ($size = 'a') {$sizeq = "image_size between 1000000 AND 10000000";}
	else {$sizeq = "image_size > 10000000";}
		
mysql_select_db($database_ImageGallart, $ImageGallart);
 $query_rstImages =sprintf("SELECT * FROM image WHERE image_keywords LIKE  (".$sizeq.")");}

any ideas why?

Hey.

Lines # 6 through 8. You need to use two = chars to compare values.

[code=php]<?php
$size = 'a';

// If you do this:
if($size = 'b') {
echo 'This will always print, and $size will be set to "b" here after.';
}

// You should do:
if($size == 'b') {
echo 'This only prints if $size is "b", and the value is not altered.';
}[/code]
?>
