Pass PHP Array via jQuery Ajax

Question

I\'ve got a php array:

$toField = explode(\",\", $ids);  //Which looks something like \'24,25,26,29\'

I want to pass this array via jQuery AJAX

Answer 1

<form id='myform'>
 <input type='hidden' name='to[]' value='1' />
 <input type='hidden' name='to[]' value='2' />

 .. etc ..
 .. rest of you're form ..
</form>

jQuery change the data: .. part to:

data: $('#myform').serialize()

Then in you're PHP:

foreach ( $_POST [ 'to' ] as $num )
{
 // do something with $num;
}

Something like this an option?

Answer 2

Few things going on I'd sort out:-

• You're missing the id 'toField' on your toField input element.

• You should be using implode() on the $id variable rather than exploding it.

• On the otherside you should be calling explode() on the recieverId string.

Answer 3

First, you probably want to use implode, and not explode, to construct your $toField variable ;-)

$ids = array(24, 25, 26, 29);
$toField = implode(',', $ids);
var_dump($toField);

Which would give you

string '24,25,26,29' (length=11)

You then inject this in the form ; something like this would probably do :

<input type="hidden"  value="<?php echo $toField; ?>">

(Chech the HTML source of your form, to be sure ;-) )

Then, on the PHP script that receives the data from the form when it's been submitted, you'd use explode to extract the data as an array, from the string :

foreach (explode(',', $_POST['receiverID']) as $receiverID) {
    var_dump($receiverID);
}

Which will get you :

string '24' (length=2)
string '25' (length=2)
string '26' (length=2)
string '29' (length=2)

And, now, you can use thoses ids...

Answer 4

you can get the string in the php code and separate it on the comma, then loop through the values.

Answer 5

just echo your array in a for each loop with some special characters like | &| . if it is multi dimensional use each character on both loops and echo it. and by using some delimiter function change it back to array in java script
