How to call a specific function in a PHP script via Ajax? - php

Question

Lets say I have a file called functions.php, and it has two separate functions inside:
One would get the time
And the other would get the date
How will I, using JQuery AJAX retrieve data from the function that retrieves the date. How do I specify in the JQuery code which function on the server to pick.
I hope I am making sense. Thanks.

Answer 1

You could include a selector in the ajax request data. For example:
$.ajax({
url: "functions.php",
data: "function=time", // or function=date if you want date
...
});
Then in your PHP code, a simple if-statement will check which one to output.
if(isset($_GET['function'])) {
if($_GET['function'] == 'time') {
// do time stuff
} elseif($_GET['function'] == 'date') {
// do date stuff
}
}

You don't specify in jQuery what function to execute in PHP. What you do is request a document, possibly with a query string, and read the results. Your functions.php script is responsible for executing whatever is requested.
So, you might from jQuery request functions.php?fn=time in one place and functions.php?fn=date in another. Then, in functions.php, you would examine the query string and execute the appropriate function for what was requested, returning the results to jQuery.

$(document).ready(function()
{
$(".link").click(function()
{
var data['func'] = "time";
var url = functions.php
$.get(url, data, function(result)
{
$("#feedback").html(result);
});
});
});
then your php file would be,
if(isset($_GET['func']))
{
if($_GET['func'] == "time")
{
showTime();
}
else
{
showDate();
}
}
function showTime()
{
//show time
}
function showDate()
{
//show date
}
Code is untested but should be a good starting point for you.

Answer 4

you can add a parameter to the url:
example:
function.php?g=1
now, on the serverside check for the get parameter:
if($_GET['g']==1)
{
echo date();
}
else
{
echo time();
}

What is the response your are getting. You are getting the response in XML or some other format. If your response is XML try with this option.
$.ajax({
url:path,
data:{projectId:inpprojectId},
dataType:"xml",
success:function(data){
$(data).find("CheckAmount").each(function(){
total = $(this).find("TotalAmount").text();
usdAmt = $(this).find("PettyCashAmount").text();
validateBudget(total,inp);
});
}
});
