jquery - Update text file in remote computer by web access? -
i have linux machine running web server php. contain text file name 'autorun.conf' - configuration file, see below.
the user can read file ('autorun.conf') local computer - using web browser (e.g. google chrome).
what happen files parse , user can see current configuration, user can update configuration , send linux.
i did parts of code : html file read file linux machine ,parse it,show , let user change it.
for example following code read file 'result' string
function button1_onclick() { console.log("button click"); $.get('/autorun.conf', function(result) { after change configuration last thing send update 'result' string server.
i did not see how can it. found plenty of file upload plugins enable me send multiple file drag , drop , find simple example 'form' enable me it.
the simplest version of ajax (jquery) upload 1 file
but did not find simple code let me send update string make file in linux.
i glad thank help.

finally, help, found solution
i show 2 different php solutions ( ajax little different)
the first solution in html file add
// big problem, how can send 'autorunfile2' string linux machine jquery.ajax({ type: "post", // http request method. url: "uploadstring.php", // url of data fetch. data: autorunfile2, // don't add data url. datatype: "text", // execute response script once it. success: function() // call function when done. { alert("success"); } }); this take string , send http post command
and in server side following php file take string , save file
<?php file_put_contents('autorun.conf1', file_get_contents('php://input')); ?> in second solution ( @ 'data' filed)
// big problem, how can send 'autorunfile2' string linux machine jquery.ajax({ type: "post", // http request method. url: "uploadstring.php", // url of data fetch. //data: autorunfile2, // don't add data url. data:{post: autorunfile2}, datatype: "text", // execute response script once it. success: function() // call function when done. { alert("success"); } }); and php in server is
<?php $fp = fopen('autorun.conf1', 'w'); $abc = $_post['post']; fwrite($fp, $abc); ?> thanks
