i know this question was probably asked 1 million times, but for the 1.000.001 time :)
i need to call a php function from JavaScript. And i am having a bit of an argument on if ajax will do it.
i don't want to send any data just a ajax call that will call and run that function.
here is what i have so far:
$.post('functions/test.php', function() {
console.log("Hooray, it worked!");
});
is this gonna run the test.php ?
thanks
It definitely runs the test.php, to check it you may do sth. on succes
$.ajax({
type: "POST",
url: "ajax/test.php",
success: function(data) {
alert(data);
}
});
But what's the purpose of sending if no data is send?
Most likely, yes. I can't guarantee it because I don't do jQuery.
This, however, will definitely run it no problems (except versions of IE so old you shouldn't care about them):
var a = new XMLHttpRequest();
a.open("GET","functions/test.php");
a.onreadystatechange = function() {
if( a.readyState == 4) {
if( a.status == 200) {
console.log("Hooray, it worked!");
// optionally, do stuff with a.responseText here
// a.responseText is the content the PHP file outputs, if any
}
else alert("HTTP error "+a.status+" "+a.statusText);
}
}
a.send();
Yes the test.php script will run, and you can grab the output from the test.php script like this (if you want to):
$.post('functions/test.php', function(data) {
//the `data` variable now stores the server response (whatever you output in `test.php`)
console.log("Hooray, it worked!");
});
In JQuery you can do:
$.post('functions/test.php', function(data) {
alert(data);
});
Whatever is returned in test.php will be put into the variable "data"
So you can do any php functions you need to in test.php and send the output back.
I always use
jQuery.ajax("url.php");
is this gonna run the test.phpYes, if the path to the php script is correct.
