Following is my JSON file:
<?php
$driver_booking = q("select * from vehicle_driver_booking where vehicle_id = ".$_REQUEST['ch']);
$array = array();
foreach($driver_booking as $bookings) {
$driver = getRow("vehicle_driver", $bookings['driver_id']);
//return date_time from only....
$date_from = date("Y-m-d",$bookings['datetime_from']);
$time_from = date("H:i:s",$bookings['datetime_from']);
//return date_time to only.....
$date_to = date("Y-m-d",$bookings['datetime_to']);
$time_to = date("H:i:s",$bookings['datetime_to']);
if($bookings['days_option'] == 1) {
$start = $date_from."T".$time_from;
$array[] = array('id' => $bookings['id'], 'title' => $driver['name'], 'start' => $start, 'allDay' => false);
} else {
$start = $date_from."T".$time_from;
$end = $date_to."T".$time_to;
$array[] = array('id' => $bookings['id'], 'title' => $driver['name'], 'start' => $start, 'end' => $end, 'allDay' => false);
}
}
echo json_encode($array);
?>
Following is part of the calendar where I am trying to get json data from above file.
eventSources: [
// your event source
{
url: '/vehicle_json.php',
type: 'POST',
data: {
// custom_param1: 'something',
//custom_param2: 'somethingelse'
},
error: function() {
alert('there was an error while fetching events!');
},
color: 'yellow', // a non-ajax option
textColor: 'black' // a non-ajax option
}
// any other sources...
],
or I tried with this following way as well...but not worked and above give me alert message and following give me nothing at all.
events: 'vehicle_json.php',
& once if above issue will resolve then I also wanted to update my events through using following where when the record save it refresh the events to show the update ones.
$.ajax({
url: "save_booking_details.php",
type: "POST",
data: {booking_id: bookingid, date_single: datesingle, date_from: datefrom, date_to: dateto},
success: function(data){
//alert(data);
//location.reload();
//$('#calendar').fullCalendar('removeEventSource', curSource[0]);
//$('#calendar').fullCalendar('removeEventSource', curSource[0]);
$('#calendar').fullCalendar('refetchEvents');
//Calendar.init();
//setTimeout(function(){ Calendar.init(); }, 10000);
}, error: function() {
alert("something went wrong!");
}
});
So can someone please help as I am looking for solution since yesterday thank you guys in advanced.
You have to provide a parameter called ch. Not sure what it is
data: {
'ch': "something I don't know"
},

My ajax function goes in error after I set the dataType to Json.
That's the code:
Ajax script:
$('#da').on("change",function() {
$.ajax({
url: "callAjaxIndex.php",
type: "POST",
dataType: "json",
data: {
method: 1,
id: $('#da').val(),
},
success: function() {
alert('test');
},
error: function() {
alert('error');
}
});
});
callAjaxIndex.php
<?PHP
require('includes/core.php');
if ( isset($_POST['method']) ) {
$sql = "SELECT tratte.nome as 'nome_arrivo', tratte.id as 'id_arrivo' FROM tariffe, tratte WHERE id_arrivo = tratte.id AND id_partenza = '".$_POST['id']."'";
$query = $conn->query($sql);
while ( $tariffe = $query->fetch_array() ) {
$result[] = array(
'id' => $tariffe['id_arrivo'],
'nome' => $tariffe['nome_arrivo']
);
}
echo json_encode($result);
}
?>
What's wrong?
Thank you
You can try this
$(document).on('change', '#da', function(){
$.post("callAjaxIndex.php", {'method': 1, 'id': $(this).val()}, function(data){
var d = $.parseJSON(data); //here is the data parsed as JSON
//data is that returned from callAjaxIndex.php file
});
});
<?php
require('includes/core.php');
if ( isset($_POST['method']) ) {
$sql = "SELECT tratte.nome as nome_arrivo, tratte.id as id_arrivo FROM tariffe INNER JOIN tratte ON id_arrivo = tratte.id WHERE id_partenza = '".$_POST['id']."'";
$query = $conn->query($sql);
while ( $tariffe = $query->fetch_array() ) {
$result[] = array(
'id' => $tariffe['id_arrivo'],
'nome' => $tariffe['nome_arrivo']
);
}
echo json_encode($result);
}
You can find out the error by changing your function to this:
//other code
error: function(data)
{
console.log(data.responseText)
}
//other code
This will tell you why it fails, might be something generic but better than 'error'
Also note:
this was done from a phone so excuse any mistakes
I'd rather this be treated as a comment until I can get to a machine to help more :)
I'm trying to pass custom error code to the client-side to ajax error function.
In the server side:
$response = array();
if ( empty($post['parent_id']) ) {
$response = array('error' => true, 'status_code' => -2);
exit();
}
$is_valid_id = RC()->is_valid_id($post['parent_id']);
$row = RC()->get_row_data($post['parent_id']);
if ( ! $is_valid_id ) {
$response = array('error' => true, 'status_code' => -1);
} else if ( ! $row ) {
$response = array('error' => true, 'status_code' => 0);
} else {
$response = json_encode($row);
}
echo $response;
Then I want to check for this status code in my js script, but couldn't find a way to do this (found ways only without trigger the error event).
$.ajax({
url: ajax_url,
data: {
'action': 'rc_parent_sign_in',
'form_data': $('#parent-sign-in-form').serialize(),
'security': security_nonce
},
type: "post",
dataType: "json",
cache: false,
success: function (response) {
var query_vars = $.param(response);
window.location.replace('http://localhost/renecassin/user-registration/?' + query_vars);
},
error: function (response) {
$('.form-control-feedback').addClass('hide');
/* Looking for something like this */
switch ( response.status_code) {
case -2 :
parent_id_form_group.addClass('has-danger').children('#empty-field').
removeClass('hide');
prent_id_input.addClass('form-control-danger');
break;
case -1 :
parent_id_form_group.addClass('has-danger').children('#not-valid-id-feedback').
removeClass('hide');
prent_id_input.addClass('form-control-danger');
break;
default :
parent_id_form_group.addClass('has-danger').children('#id-not-exists-feedback').
removeClass('hide');
prent_id_input.addClass('form-control-danger');
}
}
});
Any help will be appreciate.
It's because the response will go to your response callback, you are successfully returning an object.
The error callback will only be called if the request itself failed (timeout,404 etc..)
You need to handle your internal error codes in your success callback
I have implemented jQuery autocomplete function for my web, which is working fine. But I want the result of the autocomplete to retrieve only the data of a particular person and not the complete database result.
Below is the jQuery for the autocomplete
jQuery(document).ready(function($){
$('.product_desc').autocomplete({source:'functions/products.php?', minLength:2});
products.php
//Path for the databsae
<?php
include '../include/configuration.php';
if ( !isset($_REQUEST['term']) )
exit;
$rs = mysql_query('select id,item_name,fk_vendor_id from item where item_name like "%'. mysql_real_escape_string($_REQUEST['term']).'%" order by item_name asc ', $con);
$data = array();
if ( $rs && mysql_num_rows($rs) )
{
while( $row = mysql_fetch_array($rs, MYSQL_ASSOC) )
{
$data[] = array(
'label' => $row['item_name'],
'value' => $row['item_name']
);
}
}
else
{
$data[] = array(
'label' => 'not found',
'value' =>''
);
}
// jQuery wants JSON data
echo json_encode($data);
flush();
?>
Any solution will be appreciated.
Try this:
$(".product_desc").autocomplete({
source: "functions/products.php",
minLength: 2,
select: function(event,ui){
//do something
}
});
Try this code, Any text field having class .search the auto complete suggestion will works on server side in ajax.php file you need to return array as below:
$response = ['Computer', 'Mouse', 'Keyboard', 'Monitor'];
echo json_encode($response);
Here is sample code for auto suggest.
$(document).on('keyups','.search',function() {
$(this).autocomplete({
source: function( request, response ) {
if (request.term != "") {
$.ajax({
url: "ajax.php",
dataType: "json",
method: "post",
data: {
name: request.term
},
success: function (data) {
if (data != "") {
response($.map(data, function (item) {
var name = item.name;
return {
label: name,
value: name,
data: item
}
}));
}
}
});
}
},
autoFocus: true,
minLength: 2,
select: function( event, ui ) {
var name = ui.item.data;
$(this).val(name);
}
});
});
I asked a question earlier today (jquery select2: error in getting data from php-mysql). However, I am trying to fix it and doing that now I am getting bit strange issue. I am not sure why it is happening like this.
Below is the JavaScript code.
<div class="form-group">
<label class="col-sm-4 control-label">Product Name</label>
<div class="col-sm-6">
<input type="hidden" id="tags" style="width: 300px"/>
</div>
</div>
<script type="text/javascript">
var lastResults = [];
$("#tags").select2({
multiple: true,
placeholder: "Please enter tags",
tokenSeparators: [","],
initSelection : function (element, callback) {
var data = [];
$(element.val().split(",")).each(function () {
data.push({id: this, text: this});
});
callback(data);
},
ajax: {
multiple: true,
url: "fetch.php",
dataType: "json",
type: "POST",
data: function(term) {
return {q: term};
},
results: function(data) {
return {results: data};
},
},
createSearchChoice: function (term) {
var text = term + (lastResults.some(function(r) { return r.text == term }) ? "" : " (new)");
return { id: term, text: text };
},
});
$('#tags').on("change", function(e){
if (e.added) {
if (/ \(new\)$/.test(e.added.text)) {
var response = confirm("Do you want to add the new tag "+e.added.id+"?");
if (response == true) {
alert("Will now send new tag to server: " + e.added.id);
/*
$.ajax({

} else {
console.log("Removing the tag");
var selectedTags = $("#tags").select2("val");
var index = selectedTags.indexOf(e.added.id);
selectedTags.splice(index,1);
if (selectedTags.length == 0) {
$("#tags").select2("val","");
} else {
$("#tags").select2("val",selectedTags);
}
}
}
}
});

Here is the php code (fetch.php)
<?php
// connect to database
require('db.php');
// strip tags may not be the best method for your project to apply extra layer of security but fits needs for this tutorial
$search = strip_tags(trim($_GET['q']));
//$search='te';
// Do Prepared Query
$query = $mysqli->prepare("SELECT tid,tag FROM tag WHERE tag LIKE :search LIMIT 4");
// Add a wildcard search to the search variable
$query->execute(array(':search'=>"%".$search."%"));
// Do a quick fetchall on the results
$list = $query->fetchall(PDO::FETCH_ASSOC);
// Make sure we have a result
if(count($list) > 0){
foreach ($list as $key => $value) {
$data[] = array('id' => $value['tid'], 'text' => $value['tag']);
}
} else {
$data[] = array('id' => '0', 'text' => 'No Products Found');
}
// return the result in json
echo json_encode($data);
?>
select2 version is 3.5
Above code is able to send/receive request from database by using fetch.php.
Problem is in my database there are two records test & temp when I tag any one of them it create new tag.
It should work like this: if database have value then it won't create the new tag with same name.
Update
Tags need an id and a text. The issue you're facing is that your text doesn't match the id.
So, even if you write the same text, Select2 thinks the new text is a new option because the id don't match.
To solve your issue, you need to set the id with the same value as the text. Change the foreach of your fetch.php to the following:
foreach ($list as $key => $value) {
$data[] = array('id' => $value['tag'], 'text' => $value['tag']);
}
Update:
You also need to update the variable lastResults to avoid the duplication of tags with the same text. When you bind select2, you need to change the results property of ajax to this (based on this answer:
ajax: {
multiple: true,
url: "fetch.php",
dataType: "json",
type: "POST",
data: function(term) {
return {q: term};
},
results: function(data) {
lastResults = data.results;
return {results: data};
},
},
Note the lastResults = data.results;. Without this, the lastResults variable is always empty and, when the createSearchChoice function is executed, it will always return a new tag.
Finally it is working now. I would like to thanks #alex & #milz for their support.
Here is the full n final code. Now duplicate tags are not creating. However, i am working to add tag in database.
php/html file
<div class="form-group">

It took lots of time. Almost 3 days. I hope it will save someone efforts.
Apply the changes as in the select2.min.js (v4.0.6-rc.1) code snippet below
section 1
c.on("results:select", function() {
var a = e.getHighlightedResults();
if (0 !== a.length) {
var c = b.GetData(a[0], "data");
"true" == a.attr("aria-selected") ? e.trigger("close", {}) : e.trigger("select", {
//custom select2 tagging
if(a.attr("aria-selected")){
c.id = c.id + 1;
}
e.trigger("select", {
data: c
})
//"true" == a.attr("aria-selected") ? e.trigger("close", {}) : e.trigger("select", {
// e.trigger("select", {
// data: c
// })
}
})
section 2
this.on("query", function(b) {
a.isOpen() || a.trigger("open", {}), this.dataAdapter.query(b, function(c) {
//custom select2 tagging
let searchInput = $(".select2-search__field").val();
searchInput = {results: [{id: searchInput, text: searchInput}]};
a.trigger("results:all", {
data: c,
data: searchInput,
query: b
})
})
})

exit();
}
}
}
its not return me somthing even i print the 'moo' data
its my function its working fine i get array at the final but its dont pass it
That looks like it should work except one thing... PHP doesn't have a function 'is_number()' so unless you wrote your own you need to change your IF statement to use PHP built in 'is_numeric':
if (is_numeric($cityid_safe)) {
Its not a JS issue at all.
