Calling a php function from JQuery and wait for the response.


Recommended Posts


I have a quote system where you can select and item and give a quantity.

This will then go to the database and work out how much the item is per unit.

I have the database structure and the code to get the info back.

My issue is i need the javascript function that is handling the page being updated to wait for the response from Ajax before updating the page.

It all starts here:

$(document).ready(function() {

This is called

function updateFormNewQuoteItemChange() {

    $isConsumable = $('#itemId').find(':selected ').data('isconsumable')
    $quantity = $('#quantity').val()
    $chargeBy = $('#itemId').find(':selected').data('chargeby')

    if($isConsumable == 1 && $quantity.length !== 0){
        $iid = $('#itemId').find(':selected').val()
        getConsumablePrices($iid, $quantity);
   if ($('#currency').length) {
        $ccode = $('#currency').find(':selected').data('currency-code').toLowerCase();
        $price = $('#itemId').find(':selected').data($ccode)


If the item is consumable and has break points this is called

function getConsumablePrices($itemId, $qty) {
                    type: 'post',
                    data: {
                        "ajax": 'getConsumablePriceByQty',
                        'itemId': $itemId,
                        'quantity': $qty
                    dataType: 'json',
                    success: function(resp) {


This function returns pricing information which comes from a different table than other pricing.

I need to feed the result of this AJAX back into the function that it was called from and i think it need it to run synchronously.

Any advice, help on this would be really appreciated.

Any further information needed, please do ask.
