How to pass foreach data to ajax - php

I have stored two JSON arrays in local storage i.e,
viewbody=>json data1 , viewcollar=>json data2. I am fetching these arrays in foreach loop from local storage with data name attribute dynamically. But am not able to pass two arrays data to php ajax. Kindly help me, someone.
Below is my code,
$(document).on('click','.startDesignbtn', function() {
var product_id = $(this).data("id");
$(".getoption").each(function(){
var option_name = $(".getoption").data("name");
// alert(option_name);
var views = localStorage.getItem("view"+option_name);
});
$.ajax({
url: 'index.php?route=product/design/designMultiImage',
type: 'post',
//dataType: 'text',
data:{
'product_id': product_id,
'views' : views,
},
success: function(data) {
alert(data);return false;
var intValArray = data.split(',');
var count = 0;
$.each(intValArray,function(i){
localStorage.setItem("view_"+count,intValArray[i]);
count++;
});
localStorage.setItem('design-image',data);
localStorage.setItem('parent-id',product_id);
// var custom_link = data;
window.location = "<?php echo $customize_link;?>";
}
});
});

Use array.push() to append values to an array. Also, you need to define the array outside of the each loop otherwise you reset it every time. Also, inside the loop, use $(this) as opposed to targeting the element by class. Fixed your click function below:
$(document).on('click','.startDesignbtn', function() {
var product_id = $(this).data("id");
var views = [];
$(".getoption").each(function(){
var option_name = $(this).data("name");
// alert(option_name);
views.push("view"+option_name);
});
$.ajax({
url: 'index.php?route=product/design/designMultiImage',
type: 'post',
//dataType: 'text',
data:{
'product_id': product_id,
'views' : views,
},
success: ...

jQuery+PHP. Request/Response

I would search for the solution, but I don't know what exactly do I have to search.
The task is to grab texts with ID's (#ftext_1,..._2,..._3,..._4) in html file and send them to php file. After some manipulation with texts in php file I have to insert them back into their ID's in html file.
Here is the code:
var text_1_Replace = $('#ftext_1').text();
var text_2_Replace = $('#ftext_2').text();
var text_3_Replace = $('#ftext_3').text();
var text_4_Replace = $('#ftext_4').text();
$('#ID').on('click', function(){
var text= {
ftext_1: text_1_Replace,
ftext_2: text_2_Replace,
ftext_3: text_3_Replace,
ftext_4: text_4_Replace
}
var targetFile = 'ajax/file.php';
$.ajax({
method: 'post',
url: targetFile ,
data: JSON.stringify(text),
contentType: 'application/JSON'
}).done(function(data) {
console.log(data);
});
});
How do I edit .done function to place new texts in their old ID's(#ftext_1,..._2,..._3,..._4)? The variable with texts array is $result.
so the answer is :
}).done(function(data) {
var text = JSON.parse(data);
var text1 = text.ftext_1;
var text2 = text.ftext_2;
var text3 = text.ftext_3;
var text4 = text.ftext_4;
$('#ftext_1').text(text1);
$('#ftext_2').text(text2);
$('#ftext_3').text(text3);
$('#ftext_4').text(text4);
So, the last update for the topic: The real and nice answer is:
.done(function(data) {
var text = JSON.parse(data);
$.each(text, function(i, val){
$("#" + i).text(val);
});
This code is the solution to my question in this topic. Thank you all, who responded!
The best for you would be send named property that looks like this
$.ajax({
method: 'post',
url: targetFile ,
data: {data: text},
dataType: "json",
success: function(response){
$.each(response, function(element){
$("#"+element.name).text(element.text);
});
}
});
Then in your php you could easily iterate data from post
<?php
$data = $_POST['data'];
$response = [
];
foreach($data as $elementName => $text){
// some text management
$response[] = ['name' => $elementName, 'text' => $text];
}
return json_encode($response);
When you change your received values in php you put them in an array so that you
can call it later easily
PHP
$values = array("one"=>5,
"two"=>"something",
"three"=>$something);
echo json_encode($values);
You need to add
dataType:'json'
in Jquery since you're returning json
JQuery
$.ajax({
method: 'post',
url: targetFile ,
data: JSON.stringify(text), # or data: {"value1":value,"value2":value2},
contentType: 'application/JSON',
dataType:'json',
success: function(response){
console.log(response.one); #Will console 5
console.log(response.two); #Will console "something"
console.log(response.three); #Will console whatever $something holds in php
}
});
You can call it however you want it (response) or (mydata)...
And then you just type response.yourdata (that you declared in php)

How to insert data to database using multiple array using POST method with ajax:

I read similar answer here in this question: How to insert into MYSQL row from multiple $_POST arrays and How to insert into MYSQL row from multiple $_POST arrays but the problem is these answers do not work in my code. Is it because im using an ajax? and i only get the value of the first array.
If i also place the variable declaration inside the for loop it is not working too.
Here is my ajax:
var name = [];
$('input[name="name[]"]').map(function(){ name.push($(this).val()); }); var studid = [];
$('input[name="studid[]"]').map(function(){ studid.push($(this).val()); }); var nameStr = name != '' ? '&name='+ name : '';
var studStr = studid != '' ? '&studid='+ studid : '';
var dataString = 'subject='+ subject + '&section=' + section + studStr + nameStr;
$.ajax({ type: "POST", url: 'save.php', data: dataString, dataType: "html",
success: function(data) {
$('input#subject-field').val('');
$('input#section-field').val('');
$('input.record-input-forms').val('');
$('#status-message').css({"color":"#39b1c6"});
$('#status-message').html('Save successfully',function(){
$('#status-message').fadeOut(2000); }); },
error:function (xhr, ajaxOptions, thrownError){
alert(thrownError); } });
return false;
});
Here is my php:
if(isset($_POST['studid']) || isset($_POST['name'])){
$studid = array_map(mysql_real_escape_string, explode(",",$_POST['studid']));
$name = array_map(mysql_real_escape_string, explode(",",$_POST['name']));
for ($i=0; $i<count($studid); $i++){
$sql_1 = "INSERT INTO tbl_student(StudentID, StudentName, SubjectID) VALUES ('".$studid[$i]."', '".$name[$i]."', LAST_INSERT_ID())";
mysqli_query($con,$sql_1);
}
}
use mysql_insert_id();
instead of LAST_INSERT_ID()
You're not sending data correctly from the jQuery and its seems you'r mixing arrays and string together.
This is a simple request that posts studid-array from jQuery
var saveData = $.ajax({
type: 'POST',
data: {studid: studid},
url: 'save.php',
dataType: 'html'
});
saveData.done(function(data) {
$('input#subject-field').val('');
$('input#section-field').val('');
$('input.record-input-forms').val('');
$('#status-message').css({"color":"#39b1c6"});
$('#status-message').html('Save successfully',function(){
$('#status-message').fadeOut(2000); });
});
saveData.fail(function(ts) {
alert(ts.responseText);
});
When save.php is called, $_POST['studid'] would be set (if there are anything in the array)
If you instead do like this:
var saveData = $.ajax({
type: 'POST',
url: 'save.php?studid=' + studid,
dataType: 'html'
});
When save.php is called, $_GET['studid'] would be set (if there are anything in the array). The best way though is to use data-option in the ajax-function call (in my first case). If you choose to use this option you would have to serialize the stuid-array before putting it in as a part of an url.
UPDATE
If you want to pass multiple arrays you would have to do something like this:
var saveData = $.ajax({
type: 'POST',
data: {studid: studid, name_arr2: data_arr2},
url: 'save.php',
dataType: 'html'
});

jQuery, ajax multiple checkboxes into $_POST array

I'm trying to send $_POST data to another page to add sessions for a simple shopping cart.
I have a multiple forms within a PHP while loop each with multiple checkboxes, everything works apart from the checkboxes.
My question is how do I change this piece of code to change "item_extras" into an array?
if(this.checked) item_extras = $(this).val();
I have tried the following but, this just creates one line with all the values instead of another row within the array. If this is too confusing I could create a sample if it helps.
if(this.checked) item_extras += $(this).val();
$('form[id^="add_item_form"]').on('submit', function(){
//alert("On Click Works");
event.preventDefault();
addItem($(this));
});
function addItem(ele) {
//alert("I'm in the addItem Function");
var item_id = ele.parent().parent().find("input[name=item_id]").val(); // get item id
var item_name = ele.parent().parent().find("input[name=item_name]").val(); // get item name
var item_options = ele.parent().parent().find('#options').val(); // get selected option
var item_extras = "";
$item_extras = ele.parent().parent().find('input[name^="extra"]'); // find all extras
$item_extras.each(function() {
if(this.checked) item_extras = $(this).val(); // how do i make this into an array???
});
alert("BEFORE AJAX");
var dataString = 'item_id=' + item_id + '&item_name=' + item_name + '&item_options=' + item_options + '&item_extras[]=' + item_extras;
alert(dataString);
$.ajax({
type: "POST",
cache: false,
url: "includes/cart.php",
data: dataString,
success: function () {
$.ajax({
url: 'includes/cart.php',
success: function(data) {
$('#cart').html(data);
alert("AJAX SUCCESS");
}
});
}
});
return false;
}
you can use serialize method. Form.serialize()
$( "form" ).on( "submit", function( event ) {
event.preventDefault();
var data = $(this).serialize();
});

How to pass a nested PHP-Array via AJAX-Post?

I have a PHP-Script that expects:
$_REQUEST['asdf']['bsdf']['csdf']
to be set when it is called, and I cannot change this.
I want to call this PHP-Script via ajax:
myurl = 'example-url.com';
myid = $(this.$element).attr('id'); //gets the id of a textfield: csdf
value = 'somevalue';
$.ajax({type: 'POST',
url: myurl,
data: {'asdf[bsdf][myid]': value},
success: function (data) {
/* blabla */
}
});
It does not work though, because the var "myid" is not filled with the supposed value "csdf".
Can someone help me how to do this?
PS: I cannot access the PHP-File, so no changes in structure possible...
Try something like this:
var myurl = 'example-url.com';
var myid = $(this.$element).attr('id'); //gets the id of a textfield: csdf
var value = 'somevalue';
var param = {};
param[myid] = value;
$.ajax({type: 'POST',
url: myurl,
data: {'asdf[bsdf]' : param},
success: function (data) {
}
});
You can build the param object outside the data you pass via the ajax call to keep the correct key in place.
in JS
... {
...
data: {[['first', 'array', 'nested'], 'other', 'in', 'parent', 'array']},
...
}
In PHP getting the POST vars is with other sentence

jQuery AJAX referencing $(this) within success function

I have a voting system which sends an id of the clicked item to a PHP script, the PHP updates the database and echos back the new vote counts via an JSON encoded array.
This is the jQuery:
$(".vote_up").click(function(){
var id = this.id;
var vote = $(this).attr("class");
var data = "id=" + id + "&vote=" + vote;
$.ajax
({
type: "POST",
url: "vote.php",
data: data,
cache: false,
success: function(data)
{
for(var x in data) {
$(".votes_up").find(id).html(data[x].vote_up);
$(".votes_down").find(id).html(data[x].vote_down);
}
}
});
});
So when i construct the item in the first place, i take the record ID in the database and set it as the items ID. So what i'm trying to do is reference the exact item that was clicked and set it's HTML to the data thats coming back from the PHP. I've checked in Firebug and I'm getting correct data back but the count of votes isnt changing. Any ideas?
This is the PHP for reference:
$query = "SELECT vote_up, vote_down FROM posts WHERE id = '".$id."'";
$result1 = mysql_query($query);
$output = Array();
while ($row = mysql_fetch_array($result1)){
$output[] = Array(
"vote_up" => $row['vote_up'],
"vote_down" => $row['vote_down'],
);
}
echo json_encode($output);
If you just want this in the success: callback to refer to the element that was clicked, just set the context: property for the AJAX request.
$.ajax({
context: this, // set the context of the callbacks
type: "POST",
url: "vote.php",
data: data,
cache: false,
success: function(data) {
// now "this" refers to the element that was clicked
}
You can test it by doing something a little more generic, like:
$(this).html("yep, it works");
... then if that works, consider that it doesn't really make sense to do .html() on the same element in a loop, because each time .html() overwrites the entire content.
Use .append() instead if you're appending data from the loop:
for(var x in data) {
$(this).append(data[x].vote_up);
$(this).append(data[x].vote_down);
}
Wouldn't:
$(".votes_up").find(id).html(...);
Really just need to be:
$('#' + id).html(..);
If you define a variable within the click() method callback, you'll be able to reference it within your ajax success callback. Something similar to this should do you:
$(".vote_up").click(function(){
// Assign the clicked element to a scoped variable...
var target = $(this);
var id = this.id;
var vote = $(this).attr("class");
var data = "id=" + id + "&vote=" + vote;
$.ajax
({
type: "POST",
url: "vote.php",
data: data,
cache: false,
success: function(data)
{
for(var x in data) {
// Then refer to it within your callback
target.html(data[x].vote_up);
target.html(data[x].vote_down);
}
}
});
});
