How to hide country parameters on page load via jquery ajax php.
The code below display results from database and its working fine.
I can hide/unhide or toggle all the country values each separately via its id when button is click and is working good.
Here is my issue: How can I hide only the all country values on page load so that I can toggle or hide/unhide it as usual.
here is my coding effort so far
<html>
<head>
<script src="jquery.min.js" type="text/javascript"></script>
</head>
<body>
<script>
//toggle div on click
$(document).ready(function() {
$(".hideunhide_country").click(function(){
var id = this.id;
$("#result_"+id).toggle( 'slow', function(){
});
});
});
/*
//hide unhide div on click
$(document).ready(function(){
$(".hideunhide_country").click(function(){
var id = this.id;
$("#result_"+id).hide();
});
});
*/
</script>
<div class="content">
<?php
include('db.php');
$result = $db->prepare('SELECT * FROM users order by id');
$result->execute();
while ($row = $result->fetch()) {
$id = $row['id'];
$country = $row['country'];
?>
<div class="p">
<h1>Userid: <?php echo $id; ?></h1>
//hide country values on page load
<div id="result_<?php echo $id; ?>">
<h1><?php echo $country; ?></h1>
</div>
<input type="button" value="HideUnhide" id="<?php echo $id; ?>" class="hideunhide_country" />
</div>
<?php
}
?>
</div>
</body>

I am making a product displaying page of an ecommerce website. The products are to be filtered by brands on the basis of brands that are checked by the customer. For this I have used an ajax request everytime a brand is checked. The problem is that the page cannot receive the get variables that i am sending to the same page. The ajax request is not giving any errors and also the chrome debugger side is also not showing any error at all. This is the page:
snapshot of the products page
And this is the code of the page:

I am using alert() in the beforeSend in the ajax request and it returns the correct data as expected. But the PHP section of the page does not received the values. There are no errors on the PHP side or the browser debug window.
I checked your code line by line. and figure out that you have code for ajax inside the function named "filter" function filter().
Now you are calling this filter function on by onclick event of the element with id clear_brands
$('#clear_brands').on('click', function(){
$('.brand_check').removeAttr('checked');
filter();
$('#clear_brands').css('visibility', 'hidden');
});
and by this code i came to know that at the end your ajax call is not being made because you click event was not triggered,
So either you should trigger this event on your document get ready or you have to do it by clicking on that element.
Just think about the flow once.
i was testing your script in my local and
with some modification i have made it working.
did some changes like
at the end of the script i just putted this code below.
$(document).ready(function(){
$('#clear_brands').trigger("click");
});
And ajax call was executed..

In Chrome do Ctrl+Shift+I to open Developer Tools and check Console for errors and Network tab to see if the data is passed in request.
I have two pages. test1.php and test2.php.
All I want to do is hit submit on test1.php and test2.php be displayed within a div. This is actually working fine, BUT I need to pass an argument to test2.php to limit the results shown from the mySQL database (there'll only ever be one result from a database of 3000 items).
To be honest, I think this is within the javascript, but just not sure how to go about it....
test1.php is
<html>
<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js"></script>

$('#SubmitForm').submit(function( event ) {
$.ajax({
url: 'test2.php',
type: 'POST',
dataType: 'html',
data: $('#SubmitForm').serialize(),
success: function(content)
{
$("#DisplayDiv").html(content);
}
});
event.preventDefault();
});
});

</div>
</form>
<div id="DisplayDiv" style="background-color:red;">
<!-- This is where test2.php should be inserted -->
</div>
</div>
</body>
test2.php is
$pageNum_test1 = 0;
if (isset($_GET['pageNum_test1'])) {
$pageNum_test1 = $_GET['pageNum_test1'];
}
$startRow_test1 = $pageNum_test1 * $maxRows_test1;
mysql_select_db($database_wing, $wing);
$query_test1 = "SELECT * FROM pilots";
$query_limit_test1 = sprintf("%s LIMIT %d, %d", $query_test1, $startRow_test1, $maxRows_test1);
$test1 = mysql_query($query_limit_test1, $wing) or die(mysql_error());
$row_test1 = mysql_fetch_assoc($test1);
if (isset($_GET['totalRows_test1'])) {
$totalRows_test1 = $_GET['totalRows_test1'];
} else {
$all_test1 = mysql_query($query_test1);
$totalRows_test1 = mysql_num_rows($all_test1);
}
$totalPages_test1 = ceil($totalRows_test1/$maxRows_test1)-1;
?>
<div id="page" style="background-color:yellow;">
<?php do { ?>
<?php
echo "Hello World.";
echo $row_test1['firstname']
?>
<?php } while ($row_test1 = mysql_fetch_assoc($test1)); ?>

I think that's what you want.
I want to get questions one by one by clicking on button from mysql database table. Each question is one single row, want to get every next question by clicking on "next" button from every next row. I have made this code but this only shows first question in the table of first row in the database. My html code is:
<span ng-repeat="record in records" id="next">
<p id="hello">{{record.ques_no}}.
{{record.question}}</p>
<p><input type="text" ng-model="ans" id="ans" value=""></p>
<p align="center">Next</p>
</span>
php code getting value from database is:
$result=mysqli_query($con,"SELECT * FROM quest limit 1");
$record=array();
$number = 0;
while($row =mysqli_fetch_array($result))
{
$record[] = array(
'ques_no'=> $row['ques_no'],
'question'=> $row['question'],
'answer'=> $row['answer']
);
$number++;

Okay here is an example of what I think you are asking for:
I separated the js in the header so you could better understand. first one does the pop up box and second script does the ajax call. Remember this is a very basic example
Test.html
<!DOCTYPE html>

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>

$(document).ready(function() {
//select all the a tag with name equal to modal
$('a[name=modal]').click(function(e) {
//Cancel the link behavior
e.preventDefault();
//Get the A tag
var id = $(this).attr('href');
//Get the screen height and width
var maskHeight = $(document).height();
var maskWidth = $(window).width();
//Set heigth and width to mask to fill up the whole screen
$('#mask').css({'width':maskWidth,'height':maskHeight});
//transition effect
$('#mask').fadeIn(1000);
$('#mask').fadeTo("slow",0.9);
//Get the window height and width
var winH = $(window).height();
var winW = $(window).width();
//Set the popup window to center
$(id).css('top', winH/3-$(id).height()/3);
$(id).css('left', winW/2-$(id).width()/2);
//transition effect
$(id).fadeIn(2000);
});
//if close button is clicked
$('.window .close').click(function (e) {
//Cancel the link behavior
e.preventDefault();
$('#mask').hide();
$('.window').hide();
});
//if mask is clicked
$('#mask').click(function () {
$(this).hide();
$('.window').hide();
});
$(window).resize(function () {
var box = $('#boxes .window');
//Get the screen height and width
var maskHeight = $(document).height();
var maskWidth = $(window).width();

var winW = $(window).width();
//Set the popup window to center
box.css('top', winH/2 - box.height()/2);
box.css('left', winW/2 - box.width()/2);

});
