Image Or File Upload Works On Localhost But Not On Server

[taurus5_6]

I have an upload image page in my site and it works pretty well in my localhost.

However, when i uploaded it in my server, the error message I have in my php is displayed. What seems to be the problem?



<?php $saveto = $_POST["saveto"];//get action variable from browsefile ?>

<?
if(file_exists("../images/$saveto/" + $_FILES['txt_file']['name'])) {
echo("<center>
<font class=\"blackHeader\"><b>File already exists! Please rename the file.</b></font> <br /><br />
<a href=\"javascript: window.close()\" class=\"black\"><u>close this window</u></a>
</center>
");
}
else {
if(is_file($txt_file)) {

$target_path = "../images/$saveto/";
//Result is "uploads/filename.extension" */
$target_path = $target_path . basename( $_FILES['txt_file']['name']);
$_FILES['txt_file']['tmp_name'];

if(move_uploaded_file($_FILES['txt_file']['tmp_name'], $target_path)) {

echo("<script language=\"javascript\" type=\"text/JavaScript\">
<!--
window.opener.document.frm.$frm.value=\"$txt_file_name\";
window.opener.focus();
window.close();
//-->
</script>");
}
else {
echo("<div align=\"center\"><font class=\"blackHeader\">Could not copy file. Your file must be corrupted!</font></div>");
}
}
}
?>


What seems to be the problem? Im so confused... thanks.

I haven't looked the code but have you modified attribute of your php file so it can execute read and save ... 700
