Hello again,
I got it working now but getting stuck with something else I want to create.
This are my two scripts now:
index.php
PHP Code:
<?php
include('db.php');
include('func.php');

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$('#wait_1').hide();
$('#drop_1').change(function(){
$('#wait_1').show();
$('#result_1').hide();
$.get("func.php", {
func: "drop_1",
drop_var: $('#drop_1').val()
}, function(response){
$('#result_1').fadeOut();
setTimeout("finishAjax('result_1', '"+escape(response)+"')", 400);
});
return false;
});
});
function finishAjax(id, response) {
$('#wait_1').hide();
$('#'+id).html(unescape(response));
$('#'+id).fadeIn();
}
function finishAjax_tier_three(id, response) {
$('#wait_2').hide();
$('#'+id).html(unescape(response));
$('#'+id).fadeIn();
}
</script>
</head>
<body>
<p>
<form action="" method="post">
<select name="drop_1" id="drop_1">
<option value="" selected="selected" disabled="disabled">Selecteer Merk</option>
<?php getTierOne(); ?>
</select>
<span id="wait_1" style="display: none;">

</span>
<span id="result_1" style="display: none;"></span>
<span id="wait_2" style="display: none;">
<img alt="Please Wait" src="ajax-loader.gif"/>
</span>
<span id="result_2" style="display: none;"></span>
</form>
</p>
<p>
<?php if(isset($_POST['submit'])){
$drop = $_POST['drop_1'];
$drop_2 = $_POST['drop_2'];
$drop_3 = $_POST['drop_3'];
echo "U heeft een ";
echo $drop." ".$drop_2." geselecteerd uit ".$drop_3;
}
?>
</body>
</html>
func.php
PHP Code:
<?php
//**************************************
// Page load dropdown results //
//**************************************
function getTierOne()
{
$result = mysql_query("SELECT DISTINCT make FROM vehicles")
or die(mysql_error());
while($tier = mysql_fetch_array( $result ))
{
echo '<option value="'.$tier['make'].'">'.$tier['make'].'</option>';
}
}
//**************************************
// First selection results //
//**************************************
if (isset($_GET['func'])&& $_GET['func'] == "drop_1" ) {
drop_1($_GET['drop_var']);
}
function drop_1($drop_var)
{
include_once('db.php');
$result = mysql_query("SELECT DISTINCT model FROM vehicles WHERE make='$drop_var'")
or die(mysql_error());
echo '<select name="drop_2" id="drop_2">
<option value=" " disabled="disabled" selected="selected">Selecteer Model</option>';
while($drop_2 = mysql_fetch_array( $result ))
{
echo '<option value="'.$drop_2['model'].'">'.$drop_2['model'].'</option>';

echo "<script type=\"text/javascript\">

}, function(response){
$('#result_2').fadeOut();
setTimeout(\"finishAjax_tier_three('result_2', '\"+escape(response)+\"')\", 400);
});
return false;
});
</script>";
}
//**************************************
// Second selection results //
//**************************************
if (isset($_GET['func'])&& $_GET['func'] == "drop_2" ) {
drop_2($_GET['drop_var']);
}
function drop_2($drop_var)
{
include_once('db.php');
$result = mysql_query("SELECT * FROM vehicles WHERE model='$drop_var'")
or die(mysql_error());
echo '<select name="drop_3" id="drop_3">
<option value=" " disabled="disabled" selected="selected">Selecteer Jaar</option>';
while($drop_3 = mysql_fetch_array( $result ))
{
echo '<option value="'.$drop_3['year'].'">'.$drop_3['year'].'</option>';
}
echo '</select> ';
echo '<input type="submit" name="submit" value="Submit" />';
}
?>
When you press sumbit you get the following output when selecting:
Make = Volvo
Model = XC90
Year = 2013
"You selected a Volvo XC90 from 2013"
So that part is working allright!
The second thing I want to create is when you select the fields as above you also echo the Battery that belongs to that combination.
I have another table called "battery" in my database for example this record:
Make = Volvo
Model = XC90
Year = 2013
Battery = XXX
How can I echo "battery" too that belongs to the selected fields of the dropdown?
Something like this:
"You selected a Volvo XC90 from 2013 and you should buy the XXX battery"
I got it this far but I'm not that good in php so if somebody could help me here that would be great
Thanks in advance
