I have array made by function .push. In array is very large data. How is the best way send this to PHP script?
dataString = ??? ; // array?
$.ajax({
type: "POST",
url: "script.php",
data: dataString,
cache: false,
success: function(){
alert("OK");
}
});
script.php:
$data = $_POST['data'];
// here i would like use foreach:
foreach($data as $d){
echo $d;
}
How is the best way for this?
data: { activitiesArray: activities },
That's it! Now you can access it in PHP:
<?php $myArray = $_REQUEST['activitiesArray']; ?>
Try using this...
$(document).ready(function (e) {
$("#Form").on('submit',(function(e) {
e.preventDefault();
$.ajax({
url: "uploader.php", // Url to which the request is send
type: "POST", // Type of request to be send, called as method
data: new FormData(this), // Data sent to server, a set of key/value pairs (i.e. form fields and values)
contentType: false, // The content type used when sending data to the server.
cache: false, // To unable request pages to be cached
processData:false, // To send DOMDocument or non processed data file it is set to false
success: function(data) // A function to be called if request succeeds
{
console.log(data);
}
});
}));
});
you problem that selector ('#services') takes only first input value. You should remove id and just serialize form as below.
If all you need to pass is all values from form you can use
data: $('form#my-form').serialize() // this code puts all of the inputs into passable and readable for PHP, way.
And then in $_POST['service'] will be an array of inputs values.
For example:
<form action="save.php" method="post" id="services">
<input type="text" name="service[0]" value="1st Service" />
<input type="text" name="service[1]" value="2nd Service" />
<input type="text" name="service[2]" value="3rd Service" />
<input type="text" name="service[..]" value=".. Service" />
<input type="text" name="service[N]" value="N Service" />
</form>
In your JS:
$.post($('form#services').attr('action'), $('form#services').serialize(), function(response) {});
And then in save.php you can get an array in $_POST:
var_dump($_POST['service']);
Hope that's is exactly what you need.
You can pass the data to the PHP script as a JSON object. Assume your JSON object is like:
var stuff ={'key1':'value1','key2':'value2'};
You can pass this object to the php code in two ways:
1. Pass the object as a string:
AJAX call:
$.ajax({
type : 'POST',
url : 'result.php',
data : {result:JSON.stringify(stuff)},
success : function(response) {
alert(response);
}
});
You can handle the data passed to the result.php as :
$data = $_POST["result"];
$data = json_decode("$data", true);
//just echo an item in the array
echo "key1 : ".$data["key1"];
2. Pass the object directly:
AJAX call:
$.ajax({
type : 'POST',
url : 'result.php',
data : stuff,
success : function(response) {
alert(response);
}
});
Handle the data directly in result.php from $_POST array as :
//just echo an item in the array
echo "key1 : ".$_POST["key1"];
Here I suggest the second method. But you should try both :-)
Encode your data string into JSON.
In your PHP
Note
When you send data via POST, it needs to be as a keyvalue pair.
Thus
data: dataStringis wrong. Instead do:
data: {data:dataString}
