I have an AJAX request (using JQuery) that calls a PHP script which does some database business. The request code is as follows:
$.ajax({
url: "script.php",
data: { value: value
},
type: 'post',
success: function(output){
alert(output);
}
});
However, I wanted to see if there was a way to also (in addition to the unchanged output string) return a status. It can be as simple as an integer. The point is I want to disable a button (with Javascript) if the PHP script for any reason fails to connect to mySQL, but I still want the PHP scripts output exactly as it would be.
I tried the error option:
...
success: function(output){
alert(output);
},
error: function(output){
// do something
}
but I do not know how to make PHP display an error and continue on the rest of the script. Again, I don't want to tamper at all with the output string.
In pseudo-code, I'm looking for something like this:
$.ajax({
url: "script.php",
data: { value: value
},
type: 'post',
success: function(output){
if(output.status == 0){
alert(output);
}else{
// do something else
}
}
});
Is anything of the sort possible? Thanks for any and all help!
