I am creating a php file to alter file systems and I want to make this php run in the background on a ubuntu server. The html creates a webpage but the php does not trigger at all.
I followed a youtube video to this point but I need to pass both new and old string to the php in the Data part of my query which I am unsure how to do.
HTML code
<html>
<head>
<meta charset ='utf-8'/>
<title> JQuery test </title>
<script src= "https://ajax.googleapis.cpm/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
</head>
<body>
<td>Please type in the old string</td>
<input id= 'Old_String' />
<td>Please type in the new string</td>
<input id= 'New_String' />
<script>
$(document).ready(function() {
$('#New_String').change(function(){
$.ajax({
type: 'GET',
url: 'replace.php',
data: 'Old_String='+$('#Old_String').val(),
success : function(msg){
$('#results').html(msg);
}
})
});
});
</script>
<table border="0">
<div id="results' ></div>
</body>
My php code
<?php
$valid = true;
if (!empty($_GET["Old_string"])) {
$Old_string = $_GET["Old_string"];
} else {
$valid = false;
echo "Old string is Empty . Please Enter value to proceed
";
}
if (!empty($_GET["New_string"])) {
$New_string = $_GET["New_string"];
} else {
$valid = false;
echo "New string is Empty . Please Enter value to proceed
";
}
if ($valid) {
echo "all input correct
";
$myfile = fopen("word.txt", "r+") or die("Unable to open file!");
if (flock($myfile, LOCK_EX)) {
$text = fread($myfile, filesize("word.txt"));
$count = 0;
$newstring = str_ireplace($Old_string, $New_string, $text, $count);
file_put_contents("word.txt", $newstring);
echo "Number of changes made = " . $count;
flock($myfile, LOCK_UN); // unlock the file
} else {
// flock() returned false, no lock obtained
print "Could not lock $filename!
";
}
fclose($myfile);
}
?>
}
For some reason my PHP does not fire at all and no output is shown in the div results. Am I passing the values incorrectly or am I not quite doing this right? Please any suggestion would be appreciated. I am also trying to switch the event so that it triggers on a button click if you could show me how to do that I would very much appreciate it.
