what I'm trying to do is, i have a table named hotels and i have a page where peoples can book the hotel based on the room category. now for displaying the hotels I am using a while loop in which datas are fetch and hotels are displayed in automated divs which id same for all. so i added a $i=1 and added to the id fields and $i is incremented at the end of the while loop.
so what error I am getting is I am not able to retrieve the cost of the room category.
here is my code:
php code for getting individual hotels and show it in a div.
<?php
include 'mysql.php';
$i = 1;
$query = mysql_query("SELECT * FROM hotels WHERE location = 'portblair' ") or die("the query cannot be completed at this moment");
if(mysql_num_rows($query) <1) {
die("no hotels found");
}
while($row = mysql_fetch_array($query, MYSQL_ASSOC)){
$hotel_name = $row['name'];
$hotel_type = $row['type'];
$hotel_location = $row['location'];
$hotel_cat1 = $row['cat1'];
$hotel_cat2 = $row['cat2'];
$hotel_cat3 = $row['cat3'];
$hotel_cat4 = $row['cat4'];
$hotel_cp = $row['cp'];
$hotel_map = $row['map'];
$hotel_ap = $row['ap'];
$hotel_em = $row['em'];
if($hotel_type == "0"){
$hotel_star ='<span class="glyphicon glyphicon-star-empty"></span><span class="glyphicon glyphicon-star-empty"></span><span class="glyphicon glyphicon-star-empty"></span><span class="glyphicon glyphicon-star-empty"></span><span class="glyphicon glyphicon-star-empty"></span>';
}
if($hotel_type == "1"){
$hotel_star ='<span class="glyphicon glyphicon-star"></span><span class="glyphicon glyphicon-star-empty"></span><span class="glyphicon glyphicon-star-empty"></span><span class="glyphicon glyphicon-star-empty"></span><span class="glyphicon glyphicon-star-empty"></span>';
}
if($hotel_type == "2"){
$hotel_star ='<span class="glyphicon glyphicon-star"></span><span class="glyphicon glyphicon-star"></span><span class="glyphicon glyphicon-star-empty"></span><span class="glyphicon glyphicon-star-empty"></span><span class="glyphicon glyphicon-star-empty"></span>';
}
if($hotel_type == "3"){
$hotel_star ='<span class="glyphicon glyphicon-star"></span><span class="glyphicon glyphicon-star"></span><span class="glyphicon glyphicon-star"></span><span class="glyphicon glyphicon-star-empty"></span><span class="glyphicon glyphicon-star-empty"></span>';
}
if($hotel_type == "4"){
$hotel_star ='<span class="glyphicon glyphicon-star"></span><span class="glyphicon glyphicon-star"></span><span class="glyphicon glyphicon-star"></span><span class="glyphicon glyphicon-star"></span><span class="glyphicon glyphicon-star-empty"></span>';
}
?>
<div class="col-md-3 col-xs-6">

<?php
$i++;
}
?>
<input type="hidden" name="count" id="count" value="<?php echo $i; ?>"/>
so i want a js script that shows the cost of the category of room selected for individual hotels.
here is my js code:
function hotel_rate(){
jQuery(document).ready(function($){
var i=1;
var cnt = $("#count").val();
for(i=1;i<cnt;i++){
var cat = $("#hotel_cat["+i+"]").val();
var test = cat.split(:);
var cat_cost = parseInt(test[1]);
$("#add["+i+"]").html("Rs: "+cat_cost+" Add");
}
});
}and the error iam getting from console is: "Uncaught ReferenceError: hotel_rate is not defined" and "Uncaught TypeError: Cannot read property 'split' of undefined".
any type of help would be appriciated. thanx in advance.
</div>
Your jquery file must be something like this
function hotel_rate(){ // just define the function.
var i=1;
var cnt = $("#count").val();
for(i=1;i<cnt;i++){
var cat = $("#hotel_cat["+i+"]").val();
var test = cat.split(':');
var cat_cost = parseInt(test[1]);
$("#add[1]").html("Rs: "+cat+" Add");
}
}
jQuery(document).ready(function($){
hotel_rate(); // fire it on document ready
});
Also you missed quotes in var test = cat.split(:); it should be var test = cat.split(':');
The declaration of hotel_rate()should be inside ready function, also replace cat.split(:); by cat.split(':'); :
$(function(){
function hotel_rate(){
var i=1;
var cnt = $("#count").val();
for(i=1;i<cnt;i++){
var cat = $("#hotel_cat["+i+"]").val();
var test = cat.split(':');
var cat_cost = parseInt(test[1]);
$("#add[1]").html("Rs: "+cat+" Add");
}
}
});
Above two answers is also right.you have to declare function outside document.ready section and split function argument must have string inside it.
here is i put working code example as per your concept.you can also check paste in this fiddle php fiddle.
<div class="col-md-3 col-xs-6">
<div class="panel panel-red">
<div class="panel-heading">
Hotel name </div>
<div class="panel-body">
<img src="images/hotels/Hotel name.png" class="img-responsive"/>
<div class="my-caption">
<span class="glyphicon glyphicon-star-empty"></span><span class="glyphicon glyphicon-star-empty"></span><span class="glyphicon glyphicon-star-empty"></span><span class="glyphicon glyphicon-star-empty"></span><span class="glyphicon glyphicon-star-empty"></span> </div>
<select name="hotel_cat" id="hotel_cat_1" class="form-control" onchange="hotel_rate()">
<option value="">Category</option>
<option value="1:50">1</option>
</select>
<span id="add[1]" >Add</span>
</div>
</div>
</div>
<input type="hidden" name="count" id="count" value="1"/>
<script>
function hotel_rate(){
var cat = document.getElementById("hotel_cat_1").value;
alert(cat);
var test = cat.split(':');
var cat_cost = parseInt(test[1]);
document.getElementById("add[1]").innerHTML="Rs: "+cat_cost+" Add";
}
</script>and you are splitting value of cat by ':' for get cost of hotel so in value you must have value with : separator.
</div>
