此代码用于显示或删除在上一页的下拉框中选择的文件。有两个单选按钮,带有" view"或"删除"。视图的值为1.错误报告者只显示没有可用的文件,即使有。任何人都可以在我的代码中发现错误吗?在任何地方都有可能的语法吗?非常感谢。
<?php
// error handling function
function myErrorHandler($errno, $errstr) {

die();
}
// set error handler
set_error_handler("myErrorHandler");

这是filunlink.php页面(上一页):
<?php
$file_list ="";
$path = "/var/www/rcm/";
$show = array('.txt');
$dir = opendir($path);
while (false != ($file = readdir($dir))) {
$ext=substr($file,-4,4);
if(in_array($ext, $show)){
if (($file != ".") && ($file != "..")) {
$file_list .= "<option value = \"rcm/$file\">Go To $file</option>";
}
}
}
closedir($dir);
?>
<html><head><title>File viewer</title></head>
<div align = center>
<body background="bg.jpg">
<h3><i>File View</i></h3>
<i>Select a file to view:</i> <br>
<form action = "fileunlink.php" method = "post">

</select>
<br><br>
<input type = "radio" name = "option" value = "1">View

<input type = "submit" value = "Submit this form">

您可以尝试在第一个代码块中指定路径,使其显示为:
<?php
// error handling function
function myErrorHandler($errno, $errstr) {
echo "<b>Error: </b> [$errno] $errstr";
echo "<br>";
echo "End scripting";
error_log("Error: [$errno] $errstr", 3, "error.log");
die();
}
// set error handler
set_error_handler("myErrorHandler");
$option = $_POST['option'];
$filename = $_POST['filename'];
$path = "/var/www/rcm/";
if (file_exists($path.$filename)) {
if ($option == "1") {
$file = fopen($path.$filename, "r");
$line = "";
while (!feof($file)) {
$line .= fgets($file,1024). "<br>";
}
fclose($file);
}
else {
unlink($path.$filename)
or die ("Cannot delete your file");
$line = $filename. " deleted";
}
}
else { trigger_error(date("h:i:sa")." -> "."no file exists...\n");}
?>
<html>
<head><title>RCM Site</title></head>
<div align = center>
<body background="bg.jpg">
<body>
<div class = "rcmsite">RCM Site</div>
<div class = "centre">
<?php echo $line; ?>
</div>
<p><a href = "congrats.html"> Go Back</a></p>
</body>
</html>
