I have the following javascript file:
$.ajax({
url: './cgi-bin/make_dir.sh',
data: {
'myString' : 'myDirectory'
},
success: function(data, textStatus, jqXHR) {
console.log('OK');
}
});
And I would like my bash cgi script to retrieve the value of myString.
Is this possible using bash cgi scripting?
The answer depends on the CGI server you're using, but usually, you can access your URL values through the $QUERY_STRING environment variable. You'll need some string manipulation to get at the myString value, decoded, without the rest of the query string.
Be sure to read http://httpd.apache.org/docs/2.2/misc/security_tips.html

I am trying to use AJAX, but it seems it's not working.
var data = 'foo bar';
$.ajax({
url: 'http://localhost/index.php',
type: 'POST',
data: {data: data},
success: function(result) {
alert('success');
}
});
index.php
<?php
$x = $_POST["data"];
file_put_contents ('data.txt', data);
I get a success alert, but data.txt is empty. I have no idea why is this not working.
I am using XAMPP to test on local server.
No, using only javascript you can not write files on a server, because your javascript runs on the client side (the browser).
You need either Ajax and a server side script (like PHP) to handle the saving, or if you only want to use it with one browser (chat with yourself?), you can store stuff with javascript in the localstorage of the browser, but be aware that this storage does not last forever.
First I am conface that I am Newbie to php,
I am using jquery(knockout js) at client side & PHP at server side. my code.
Client side: I am using knockout js(Javascript). to call my PHP service.
My Code:
self.VMSaveEditUserMode = function () {
try {
var params = { "ClientData": [controllerVM_.ClientID(), controllerVM_.VMList[0].ClientName(), controllerVM_.VMList[0].ShortName(), controllerVM_.VMList[0].Address(), controllerVM_.VMList[0].CreatedBy(), controllerVM_.VMList[0].CityName(), controllerVM_.VMList[0].PostalCode(), controllerVM_.VMList[0].ContactEmail(), controllerVM_.VMList[0].ContactPhone(), controllerVM_.VMList[0].IsCorporate()] };
$.ajax({
type: "POST",
url: URL + "index.php/phpService/SaveClient/" + controllerVM_.TokenKey(),
data: JSON.stringify(ko.toJS(params)),
contentType: "application/json",
async: true,
dataType: 'json',
cache: false,
success: function (response) {
},
error: function (ErrorResponse) {
if (ErrorResponse.statusText == "OK") {
}
else {
alert("ErrorMsg:" + ErrorResponse.statusText);
}
}
});
}
catch (error) {
alert("Catch:" + error);
}
}
Server Side My Code, I am using this PHP code to connect with DB.
PHP Code:
public function SaveClient($userToken)
{
$value = json_decode($Clientdata);
echo $value->ClientData[0];
}
*My Question *:
I am not clear on how to POST data in PHP ? I tried with $_POST[''] method as well as many more.
I am using eclipse as a php framework. so, not able to debug it when i post the data.Normally mode i am able to debug my code.but not from remotely.for that i made changes on php.ini file also.
How to get Response of Post Data on php code ?
How to debug via remote post ?
My Request sample:
suppose i use:
For, data: params, only at that time my request format is.
ClientData%5B%5D=4&ClientData%5B%5D=kamlesh&ClientData%5B%5D=KAM&ClientData%5B%5D=Junagadh&ClientData%5B%5D=me&ClientData%5B%5D=SANTA+ROSA&ClientData%5B%5D=76220&ClientData%5B%5D=kamlesh.vadiyatar%40gmail.com&ClientData%5B%5D=9998305904&ClientData%5B%5D=false
For, data: JSON.stringify(ko.toJS(params)),
{"ClientData":["4","kamlesh","KAM","Junagadh","me","SANTA ROSA","76220","kamlesh.vadiyatar#gmail.com","9998305904",false]}
If I understand correctly you need to create a PHP service which is able to receive REST-like requests from client.
In order to do thad you need to access raw POST data. In PHP its being done like this:
$ClientData = file_get_contents('php://input');
You can read more about php://input in the wrappers documentation.
Of course from the client's side the data need to be sent using the POST method and as raw data, i.e. as a string. You can obtain a string from object using JSON.stringify() which you already do.
If you pass an object, it will be converted to string internally by jQuery using query-string format. More on that in the jQuery documentation for $.ajax (the most importatnt options being data and processData).
Just pass the ajax data param as an object, don't convert it into JSON. Then in PHP use $_POST directly.
Use firebug or chrome dev tools to analyze the ajax request and see which data is sent
Use this simple jquery function to accomplish your task
$.ajax({
type: "POST",
url:"scripts/dummy.php",
data:"tbl="+table,
dataType:"json", //if you want to get back response in json
beforeSend: function()
{
},
success: function(resp)
{
},
complete: function()
{
},
error: function(e)
{
alert('Error: ' + e);
}
}); //end Ajax
in PHP use:
if(isset($_POST['ClientData'])){
$client_data = $_POST['ClientData']
}
now $client_data variable should contain the array.
For debugging purpose you can use php's built-in print_r() function. It's pretty handy.
here's is an example:
//make sure it's post request
if(isset($_POST)){
//now print the array nicely
echo "<pre>";
print_r($_POST);
echo "</pre>";
}
I am trying to utilise JQuery Ajax to call a javascript file. I need to pass it some parameters but I am not certain how to when using javascript (PHP seems simpler). Here is my call:
function getDocument(parameters) {
$.ajax({
type: "GET",
url: "js/document.js",
dataType: "script",
data: "info=hellothere",
success: function(msg) {
},
error: function(jqXHR, textStatus, errorThrown){
}
});
}
All I would like to do, is print out the contents of the parameter 'info' in document.js
So essentially is should print 'hellothere'.
You're better off using PHP.
Change the URL to document.php, and within that file do the following:
echo $_GET['info'];
url: "js/document.js"
Should be the path to the Server file
You cannot send ajax request to your .js file using Ajax request
Send the request to the .php file and write up your method in there to process the data.
Ajax Request is primarily used to send data to and forth from the Client side to server side ..
If you want to access the data between two .js files better store that data in a cookie or a local storage
I am new to Javascript. I need to parse XML using javascript or jQuery which is another server. I tried by using the below code. But when I executed it, it was not going to success method.
I was able to parse the XML which is in the same folder. Is it possible in javascript to access content from another server. I read the Same Origin Policy.
I was able to get the success message, but cant get the xml data
$.ajax({
type: 'GET',
url: 'http://10.47.5.69/myxml.xml',
dataType: "xml",
success: function(data){
alert('success');
$(data).find("Node").each(function() {
alert($(this).find("element").text());
});
},
error: err
});
function err(xhr, reason, ex)
{
alert('xhr.status: ' + xhr.status);
alert('ex "'+ex);
}
You cannot load something from another server due to cross-domain security checks.
However for javascript, there is a workaround: the JSONP technique: http://en.wikipedia.org/wiki/JSONP
It is used for JSON data but it can just as well be used for any string data. But it will only work if you have some degree of control (i.e. can install a script) on that server.
Another alternative is to proxy that URL on your own server. That might be easier.
I'm trying to understand how I can use Python and javascript so that I can use POST/GET commands. I have a button that sends a request to server-side python, and should return a value. I understand how to print out a response, but I want to pass a value to a javascript variable instead of just print thing the response.
For example, my javascript sends a string to the python file using the jquery POST function:
<script>
function send(){
$.ajax({
type: "POST",
url: "pythondb.py",
data:{username: 'william'},
async: false,
success: function(){
alert('response received')
},
dataType:'json'
});
}
</script>
Then using the python cgi module I can print out the value of username:
#!/usr/bin/env python
import cgi
print "Content-Type: text/html"
print
form = cgi.FieldStorage()
print form.getvalue("username")
however I am not receiving the data in the same way that the php echo function works. Is there an equivalent to 'echo' for the python cgi module?
I have read this question which explains the different python frameworks that can be used to communicate between browser and server; for the moment I was hoping to keep things as simple as possible and to use the cgi module, but I don't know if that is the best option.
Your success: function can take a parameter, to which jQuery will pass the contents of the response from the AJAX request. Try this and see what happens:
<script>
function send(){
$.ajax({
type: "POST",
url: "pythondb.py",
data:{username: 'william'},
async: false,
success: function(body){
alert('response received: ' + body);
},
dataType:'json'
});
}
</script>
P.S. Why are you using async: false? That kind of defeats most of the point of AJAX.
Your json is not in proper json format.
According to http://api.jquery.com/jquery.parsejson/,
username needs to be in quotes
you can only use double quotes
It would look like this:
{"username": "william"}
Also, your alert should have a semi colon on the end. I can't guarantee this answer will fix your problem, but it may be that your data isn't getting passed to cgi at all.
