Send array with ajax in codeigniter

Question

How can i pass an array with ajax? My code in view:

$(document).ready(function(){
 $('#btn-send').click(function(){
 var value = {
 'name': $('#name').val(),
 'phone': $('#phone').val(),
 'mail': $('#mail').val(),
 };
 $.ajax({
 type: 'POST',
 url: '<?php echo site_url('customer_add/test'); ?>',
 data: value,
 success: function(resp){
 $('#error').html(resp);
 }
 });
 });
});

My test method:

public function test5(){
 $data = $this->input->post["value"];
 $name = $data['name'];
 echo $name; 
}

In params - in the inspect element - there are data but in response, there's nothing to return. What's wrong? Thank's in advance.

• SAUMYA: try this success : function(data) { //alert("ok"); }, error: function(er){ alert("There is some error"); console.log(er.responseText); }
• Pardeep Poria: You are requesting the function test in ajax and in the code you are showing us function test5 in your server script ???

Answer 1

First, you can handle your error at the error section of $.ajax by error: function(xhr) {},

$.ajax({
 type: 'POST',
 url: '<?php echo site_url('customer_add/test'); ?>',
 data: {
 name: $('#name').val(),
 phone: $('#phone').val(),
 mail: $('#mail').val()
 },
 error: function(xhr) {
 alert('error');
 },
 success: function(resp){
 $('#error').html(resp);
 }
});

Next, type: 'POST' means the form would post the fields out by the method POST.
So that we can catch them by $_REQUEST or $_POST.

In Codeigniter, the way to catch the posted fields is $this->input->post('name');.
There's an error in your syntax.

public function test5(){
 $data['name'] = $this->input->post('name');
 $data['phone'] = $this->input->post('phone');
 $data['mail'] = $this->input->post('mail');
 echo $data;
}

Hope it would be help.

Answer 2

You send data through ajax and you create a array of value with key:value pair when data send to server using post so you can get this whole array in one single variable using.

public function test5(){
 $data = $this->input->post();
 $name = $data['name']; echo $name;
 $phone = $data['phone']; echo $phone;
 $mail = $data['mail']; echo $mail;
}

you dont have to mention value key in $data = $this->input->post["value"];

and the second thing

you are writing wrong syntax $this->input->post["value"];

the write syntax is $this->input->post("value");

but in $this->input->post("value"); case you cant get value because there is no key with value name.

• meph: Thanks quarksera :) You're right. I changed it to data: {value: value}, and now i gat response but the problem is in this way, form validation doesn't work. At first it returns the validation errors but if i write data, the error are still the same and doesn't change!
• quarksera: do you use codeignitor form validation or custom give me some hint otherwise i cant do anything
