updating combo values - php

Question

I have a combo that simply displays some mysql databases. I also have a form that creates a database. I would like to dynamicly refresh the combo (if possible) to also display the new database created by the form. here is a snippet of the code:
<div id="tools">
<P>Add a Set list:<br>
<LABEL for="labelName">Set List Name: </LABEL>
<INPUT type="text" name="slName" id="slName"><button id="createSL" value="Create Setlist">Create Set</button>
</P><br>
<P>Delete a Set list:<br>
<? include("remSLcombo.php"); ?> <button href="#" type="button" id="delSl">Delete Setlist</button>
</P>
<p>Check how to reload combos</p>
</div><BR>
<? include("combo.php"); ?>
The Jquery function that is called to create the database:
$('#createSL').click(function(){
var sendIt = $("#slName").val();
$.ajax({
type: "POST",
url: "createSL.php",
data: {slName : sendIt},
error: function(e){
alert("The PHP Call failed! hmmm");
alert(e.status);
},
success: function(response){
alert(response);
}
});
$("#selcombo").load("combo.php");
$("#tools").hide().html(data).fadeIn('fast');
});
Combo.php:
<?php
echo '<select id="tunelist" name="tunelist" >';
$link = mysql_connect('localhost', 'setlist', 'music');
$query = mysql_query("SHOW DATABASES");
echo '<option>Select a Show</option>';
while ($row = mysql_fetch_assoc($query)) {
if ($row['Database'] == "information_schema"){}
elseif ($row['Database'] == "performance_schema"){}
elseif ($row['Database'] == "mysql"){}
else{
echo '<option value="'.$row['Database'].'">'.$row['Database'].'</option>';
}
}
echo '</Select>';
?>
How do I go about refreshing the values in the combo (made by combo.php) after a database is added using the form above?
Any help as always is greatly appreciated!

Answer 1

Try moving
$("#selcombo").load("combo.php");
to inside of your success function:
success: function(response){
alert(response);
if (response == true) // or something like this to ensure the success of the operation
$("#selcombo").load("combo.php");
}

Answer 2

What you have to do is to give back in createSL.php the code of the new combobox and loaded there.
This is your code
success: function(response){
alert(response);
}
Write something like:
success: function(response){
$('#tunelist').html(response);
}
Where the response is similar to Combo.php
