Trying to write to a txt file upon button click. Not sure how to do it and my code isnt working. Im starting to think i might need AJAX? If so, can someone give me a quick pointer in the right direction? Please and thankyou in advance!
Here's my code:
<?php
//write to file on button event
function buttonWrite()
{
$filename = 'button.txt';
@ $fp = fopen("messages/".$filename, 'wb');
if (!$fp)
{
echo '<p><strong>Cannot generate message file</strong></p></body></html>';
exit;
}
$outputstring = 'Hello, i have been generated by the button';
fwrite($fp, $outputstring);
}
?>
<html>
<head>
<title>Button Writer</title>
</head>
<body>
<button type="button" onclick="buttonWrite()">Write to File</button>
</body>
</html>
UPDATE! None of these answers actually work at all.. Not sure if its the server im hosting on or what, but yeah the just dont work.. any ideas guys ?

- You cannot call a PHP-function from the HTML. You need to, as you said, make an AJAX call to the php-file, which will in turn excecute the code. – Eric Commented Jan 6, 2014 at 9:49
- JavaScript is front-end script, so it can not access files on your server; so yes, you do need ajax call to php script, that will do the job for you. Here is a starter for you: tizag./ajaxTutorial – Peon Commented Jan 6, 2014 at 9:49
- jQuery ajax has always been the easiest way to implement ajax functionality, you could refer this official jquery link ,api.jquery./jquery.ajax – dreamweiver Commented Jan 6, 2014 at 9:53

Reset to default 2Create a PHP file .Lets say "abc.php".It contains:
<?PHP
$filename = 'button.txt';
@ $fp = fopen("messages/".$filename, 'wb');
if (!$fp)
{
echo '<p><strong>Cannot generate message file</strong></p></body></html>';
exit;
}
else
{
$outputstring = 'Hello, i have been generated by the button';
fwrite($fp, $outputstring);
Echo "Message inserted";
}
?>
HTML file
<html>
<head>
<title>Button Writer</title>
<script type='text/javascript' src='//code.jquery./jquery-1.10.1.js'></script>
</head>
<body>
<button id="button1" type="button">Write to File</button>
</body>
<script type='text/javascript'>
$('#button1').click(function(){
$.ajax({
type: "POST",
url: "abc.php",
data: "",
success: function(msg){
alert(msg);
},
error: function(XMLHttpRequest, textStatus, errorThrown) {
alert("Some error occured");
}
});
});
</script>
</html>
You do it wrong - javascript and php can't be executed together in HTML. What you need to do is to create:
1) "onclick" button event, that execute AJAX request to your server. I'll use jQuery in my examples for the simplicity.
<button id="btn">SAVE FILE</button>
<script type="text/javascript">
// bind click event to button
$('#btn').click(function() {
// send ajax request to save.php (using POST method)
$.post('save.php', { text: "sample text", function(data) {
// output response to console
console.log(data);
});
});
</script>
2) create save.php file - it will be responsible for saving your data to the file
<?php
// saving sample text to file (it doesn't include validation!)
file_put_contents('file.txt', $_POST['text']);
die('file has been saved');
?>
Entire Code
Save.php
<?php
//write to file on button event
function buttonWrite()
{
$filename = 'button.txt';
$outputstring = "Hello, i have been generated by the button'\n";
file_put_contents($filename, $outputstring, FILE_APPEND | LOCK_EX);
}
?>
index.php or index.html
<html>
<head>
</head>
<body>
<form name="input" action="save.php">
<input type="submit" value="Write to File">
</form>
</html>
This should work it will write the $outputstring to the button.txt using the file_put_contents function
