I am writing an application and I cannot get the JSON using Ajax. Or better, when using XAMPP locally it works correctly, but it doesn't when I upload everything on my domain. What's wrong? PHP seems to work fine, I just get the error function instead of success.
function groupGetDocsList() {
$.ajax({
url: '../php/group_docs_list.php',
dataType: 'json',
success: function(data) {
docsList = $.parseJSON(data);
for(var i = 0; i < docsList.length; i++) {
docsListNames[i] = docsList[i].replace(/_/g, ' ').replace('.html', '');
}
groupSearchDocs();
},
error: function(data) {
$('#group-docs-list-found').append('No documents found.');
$('#group-docs-list').append('Error loading documents.');
}
});
}
Also without $.parseJSON
it isn't working.
The console shows this (that is not for my code I suppose since it appears simply including the jQuery javascript):
event.returnValue is deprecated. Please use the standard event.preventDefault() instead.
The status code is 200
and I get a parseerror
.
I have validated my JSON code with many online validators: they all validate it correctly except for one, but I cannot understand why. It blocks itself on a parenthesis (

The 2 pieces of code between ** and ** at the end of the JSON is where the validator fails and returns the following errors:
Error:Expecting object or array, not number.[Code 3, Structure 2]
Error:Strings should be wrapped in double quotes.[Code 17, Structure 3]
Error:Expecting ), after ].[Code 2, Structure 6]
Error:Extra closing ][Code 14, Structure 6]
It is sufficient to delete the (
before the 5
in the penultimate string and the JSON is correctly validated.
I have checked many times the URL path, it's correct. The PHP code is this:
<?php
header('Content-Type: application/json');
$fileToString = file_get_contents('../documents/');
$stringToArray = preg_match_all('/[(A-Za-z0-9_\-)]+.html(?=<)/', $fileToString, $matches, PREG_PATTERN_ORDER);
$jsonDic = json_encode($matches[0]);
echo $jsonDic;
?>
If opening this file, it correctly prints the json.
