Hi I'm trying to process an array in a php class by passing it through ajax.
I have read various tutorials that suggest using the JSON.stringify directive before the ajax call, but in doing so when I go to print an array, I saw that it is encoded as a string ...
How can I process it as an php array instead?
This is the code I used:
in js file:
let pw_script_vars = cc_object.ajax_url;
let pw_script_nonce = cc_object.itemNonce;
let lista_carte_finali =[18, 4, 12, 7, 16, 2, 3, 9, 1, 8];
let jsonString = JSON.stringify(lista_carte_finali);
function crea_tasto() {
$.ajax({
type: 'POST',
url: pw_script_vars,
cache: false,
data: {
action: 'carica_carte',
nonce: pw_script_nonce,
dati_carte: {dati_carte:jsonString}
},
success: function (dati_carte) {
console.log(dati_carte);
},
error: function () {
console.log('nessun dato');
}
});
}
$('#start_game').on('click', function () {
crea_tasto();
})
mentre lato server ho :
public function carica_carte() {
if (isset($_REQUEST)) {
foreach($_REQUEST['dati_carte'] as $d){
echo $d;
}
}
die();
}
if (isset($_REQUEST)) {
$data = json_decode(stripslashes($_REQUEST['dati_carte']));
foreach($data as $d) {
echo $d;
}
}

I am using select2 version 4.0.8 with ajax search. In my angular 4 application with ajax call. Till searching and populating result it works fine. But after that when I click on any option it doesn't call method specified in templateSelection option.
Below is the code I am using:
jQuery(".suggestion"+i).select2({
placeholder: 'Select Countries',
ajax: {
url: AppConstants.facebookBaseUrl + "/search",
dataType: 'json',
delay: 250,
type: "GET",
beforeSend: (request)=> {
request.setRequestHeader("Authorization", "Bearer "+this.user.facebookPage_Token);
},
data: (params)=> {
return {
q: params.term, // search term
location_types: this.facebookFilters[i].filter,
type: "adgeolocation",
page: params.page
};
},
processResults: function (data, params) {
// parse the results into the format expected by Select2
// since we are using custom formatting functions we do not need to
// alter the remote JSON data, except to indicate that infinite
// scrolling can be used
params.page = params.page || 1;
return {
results: data.data,
pagination: {
more: (params.page * 30) < data.total_count
}
};
},
cache: true
},
multiple:true,
minimumInputLength: 2,
templateResult: formatRepo,
templateSelection: formatRepoSelection
});
function formatRepo (repo) {
if (repo.loading) {
return repo.text;
}
var $container = jQuery("<option (click)='selectCountry($event)' class='country_name' value='"+repo.key+"'>"+repo.name+"</option>");
return $container;
}
function formatRepoSelection (repo) {
var $container = jQuery("<option class='selectedCountry' value='"+repo.key+"'>"+repo.name+"</option>");
return $container;
// return repo.key || repo.text;
}
And HTML:
<select class="form-control" name="selected[]" [ngClass]="'suggestion'+i"></select>
What I am doing wrong here?
thanks in advance!
Try by changing option to span as:
function formatRepoSelection (repo) {
var $container = jQuery("<span class='selectedCountry'>"+repo.name+"</span>");
return $container;
// return repo.key || repo.text;
}
How to define select2 default AJAX value?
I've tried many but still cannot get it working.
Below is my code:
$("#qrcode_group_rowid").select2({
ajax: {
url: "app/qrcode/qrcode_group_select_service.php",
dataType: 'json',
delay: 250,
data: function (params) {
return {
q: params.term, // search term
page: params.page
};
},
processResults: function (data, params) {
params.page = params.page || 1;
return {
results: data.items,
pagination: {
more: (params.page * 50) < data.total_count
}
};
},
cache: true
},
placeholder: 'Please select',
escapeMarkup: function (markup) { return markup; },
minimumInputLength: 0,
templateResult: formatRepo,
templateSelection: formatRepoSelection
});
function formatRepo (json) {
if (json.loading) {
return json.text;
}
var markup = json.group_name;
return markup;
}
function formatRepoSelection (json) {
return json.group_name;
}
and my JSON data:
{
"total_count": 897,
"items": [{"id": 901,"group_name": "TEST25-117"},{"id": 1,"group_name": "TEM117"}]
}
What am I doing wrong and how can I fix it?
You should send the following information in the PHP method (there may be a limitation of working with the IP address in eloquent)
/** #var Collection $btsNodes */
$btsNodes = BtsNode::where('node_code' , 'like' , '%'.$request->get('q').'%')
->get(['node_code']);
// ->toArray();
$items = $btsNodes->map(function ($item){
return [
'id' => $item['node_code'],
'node_code' => $item['node_code']
];
});
return ['items' => $items];
I'm making litte app to get pages by URL and check their title.
I need check URLs line by line which is user pasted in textarea.
Process sequence :
Check URL > append response to page > then check next url......
Here is my code :
HTML :
<textarea id="textarea" name="urlLine"></textarea>
<button type="button" name="action" id="check">Check IT!</button>
Js :
function getResp(req) {
var uri = req.shift();
$.ajax({
type: 'POST',
url: 'r.php',
async: true,
data: {'uriLine': uri},
success: function (msg) {
$('.collection').append(msg);
$('body').animate({
scrollTop: height,
}, 500)
},
fail: function (msg) {
console.log(msg);
}
});
if (typeof uri !== 'undefined' && uri.length > 0) {
setTimeout(getResp, 5, req);
} else {
alert('Finish');
}
}
$(document).ready(function () {
$('#check').click(function () {
var uris= $('textarea').val().split('\n');
getResp(uris);
});
PHP :
sleep(5); // I don't know why i'm adding. Just wait for performance.
$title = 'title_i_searching';
$adress = $_POST['uriLine'];
if($check->chekURL('https://'.$adress) == $title){
echo ' OK';
}else{
echo 'NOT OK';
}
PHP CLASS :
class checkES
{
public $url;
public function chekURL($url){
$arrContextOptions=array(
"ssl"=>array(
"verify_peer"=>false,
"verify_peer_name"=>false,
),
"http"=>array(
"timeout"=> 5
)
);
$str=
file_get_contents($url,false,stream_context_create($arrContextOptions));
if(strlen($str)>0){
$str = trim(preg_replace('/\s+/', ' ', $str));
preg_match("/\<title\>(.*)\<\/title\>/i",$str,$title);
return $title[1];
}
}
public function parseByLine($content){
$lines = preg_split('/\r\n|[\r\n]/', $content);
return $lines;
}
}
But when i run this code for example; in 20 URL searching on 5th url page alert 'finish'. But append function still continue.
Sometimes, page crash down.
I could not find the healthy method.
I wish i was explain. Sorry for bad language.
Try moving the code to process next uri in success function like this:
function getResp(req) {
var uri = req.shift();
$.ajax({
type: 'POST',
url: 'r.php',
async: true,
data: {'uriLine': uri},
success: function (msg) {
$('.collection').append(msg);
$('body').animate({
scrollTop: height,
}, 500);
if (typeof uri !== 'undefined' && uri.length > 0) {
setTimeout(getResp, 5, req);
} else {
alert('Finish');
}
},
fail: function (msg) {
console.log(msg);
}
});
}
how to pass a variable with the help of ajax jquery into a function directly, which is on another page
function show_data2(str1) {
xml2http = new XMLHttpRequest();
xml2http.onreadystatechange = function () {
if (xml2http.readyState === 4 && xml2http.status === 200) {
document.getElementById("show_data_sal").innerHTML = xml2http.responseText;
}
};
xml2http.open("POST", "functions.php?r=" + str1, true);
xml2http.send(str1);
};
functions.php
class querydb
{
function useHere()
{
...I want to use that variable 'r' here.
}
}
If you are using jQuery, this will be the easiest way to send post data via ajax:
var jqxhr = $.ajax( {
method: "POST",
url: "functions.php",
data: { r: "some value", s: "another value" }
})
.done(function() {
alert( "success" );
})
.fail(function() {
alert( "error" );
})
.always(function() {
alert( "complete" );
});
function.php
class querydb
{
function useHere()
{
// We're sending our post data as json so we'll need php to decode it for us to use.
$foo = json_decode($_POST[], true);
// you can now access your variables like an array
$bar = $foo['r'];
}
}
Just be sure to clean anything from post before you do anything with it to prevent any malicious parameters coming through
Right, i only want a very simple ajax request to get this working. im new with yii 2.0 framework you see.
in my view index.php:
function sendFirstCategory(){
var test = "this is an ajax test";
$.ajax({
url: '<?php echo \Yii::$app->getUrlManager()->createUrl('cases/ajax') ?>',
type: 'POST',
data: { test: test },
success: function(data) {
alert(data);
}
});
}
Now when i call this i assume that it should go to my CasesController to an action called actionAjax.
public function actionAjax()
{
if(isset($_POST['test'])){
$test = "Ajax Worked!";
}else{
$test = "Ajax failed";
}
return $test;
}
EDIT::
Ok great, so this works up to here. I get back the alert that pops up with the new value for $test. However i want to be able to access this value in php as ultimately i will be accessing data from a database and ill be wanting to query and do various other things.
So how do i now use this variable in php instead of just the pop up alert()?
Here is how you can access the post data in controller:
public function actionAjax()
{
if(isset(Yii::$app->request->post('test'))){
$test = "Ajax Worked!";
// do your query stuff here
}else{
$test = "Ajax failed";
// do your query stuff here
}
// return Json
return \yii\helpers\Json::encode($test);
}
//Controller file code
public function actionAjax()
{
$data = Yii::$app->request->post('test');
if (isset($data)) {
$test = "Ajax Worked!";
} else {
$test = "Ajax failed";
}
return \yii\helpers\Json::encode($test);
}
//_form.php code
<script>
$(document).ready(function () {
$("#mausers-user_email").focusout(function () {
sendFirstCategory();
});
});
function sendFirstCategory() {
var test = "this is an ajax test";
$.ajax({
type: "POST",
url: "<?php echo Yii::$app->getUrlManager()->createUrl('cases/ajax') ; ?>",
data: {test: test},
success: function (test) {
alert(test);
},
error: function (exception) {
alert(exception);
}
})
;
}
</script>
You can include js this way in your view file:
$script = <<< JS
$('#el').on('click', function(e) {
sendFirstCategory();
});
JS;
$this->registerJs($script, $position);
// where $position can be View::POS_READY (the default),
// or View::POS_HEAD, View::POS_BEGIN, View::POS_END
function sendFirstCategory(){
var test = "this is an ajax test";
$.ajax({
url: "<?php echo \Yii::$app->getUrlManager()->createUrl('cases/ajax') ?>",
data: {test: test},
success: function(data) {
alert(data)
}
});
}
