I suppose you want to rename all files in the directory on click of a button. $handle is already a handle to the directory and $file_path contains the path of the directory. Also assuming that the name of all input fields for new filename field is new_name[]. You need to iterate though each file in the directory and rename it like below:
if (isset($_POST['submit'])) {
$i = 0;
while($file = readdir($handle)) {
rename ($file_path.$file, $file_path.$_POST['new_name'][$i]);
$i++;
}
header("Location: /php rename/");
exit();
echo "name changed";
}
else {
echo "name was not changed";
}
Ajax Solution with Javascript
test.php
<html>
<head>
<script>
function changename(id,dirpath){
new_name = document.getElementById(id + "_new_name").value;
old_name = document.getElementById(id + "_old_name").value;
old_file_path= dirpath + old_name;
new_file_path = dirpath + new_name;
var xmlhttp;
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById("response").innerHTML=xmlhttp.responseText;
document.getElementById(id + "_old_name").value=new_name;
}
}
xmlhttp.open("GET","change_name.php?old_name="+old_file_path+"&new_name="+new_file_path,true);
xmlhttp.send();
}
