动态填充下拉框不适用于“空格”

Question

I have a dynamic drop down box which one the first selection, populates the second drop down from the database.

include("connect.php");
$choice = mysql_real_escape_string($_GET['choice']);

$query = "SELECT * FROM locations WHERE county_name='$choice' ORDER BY town_name ASC";

$result = mysql_query($query);
while ($row = mysql_fetch_array($result)) {
        echo "<option>" . $row{'town_name'} . "</option>";
}

This works perfectly for any 'county_name' variable that is 1 word ie London, Essex. But when they pick 'East Sussex' for example, it returns nothing.

I thought the mysql_real_escape_string was the problem, so I removed that and yet the problem was still occurring.

The javascript to plug the data into the second drop down is as follows:

$(function() {              
$("#select_county").change(function() {
$("#select_town").load("include_mx/getter.php?choice=" + $("#select_county").val());
    });     
});

Any help would be appreciated as to why the 'spaces' in-between are having no success.

Many thanks in advance.

Answer 1

I am unsure of the quickest most simplest answer, how ever, this works for me:

Any county with a 'space' has been replaced with 'West+Sussex':

`str_replace(" ","+","$variable");

Because I didn't want to show the '+'s I used this:

$c=$row['county_name']; $county = str_replace("+"," ","$c"); echo "<option value='$c'>$county</option>";

That seem's to work all the time now and is pretty robust.
