Hi,
I have a problem on my web application with jQuery $.post.
My javascript is :
$.post("create-account", { name: "John", pass: "test" },
function(data) {
alert("Data Loaded: " + data);
});
and the Php
echo 'data received';
The Php is called and executed but, I can not get the response in my javascript
Can you help me ?
thanks :) |

What are your response headers for AJAX request in Firebug? |

Look like you’re getting your response back (Content-Length: 122). Try
$.post("create-account", { name: "John", pass: "test" },
function(data) {
console.log(data);
alert("Data Loaded: " + data);
});
and check Firebug console for returned variable. |

Does Firebug report any errors? Try replacing post() with more customizable ajax():
$.ajax({
type: "POST",
url: "create-account",
data: "name=John&pass=test",
success: function(){
console.log('success')
},
error: function(){
console.log('error')
},
complete: function(){
console.log('completed')
}
});

Check your request headers and make sure URL is correct, change
url: "create-account"
accordingly. |

Is ‘error’ string being logged in console? If so, update
error: function(){
console.log('error')
}
with
error: function(jqXHR, textStatus, errorThrown){
console.log(jqXHR);
console.log(textStatus);
console.log(errorThrown);
}
and check Firebug console for returned variables. They should give you information why the call is failing. |

You should:
$.post("<?=base_url()?>create-account", { name: "John", pass: "test" }, function(data){
alert("Data Loaded: " + data);
});
