首先,我在这个论坛上发现了一些关于此问题的主题,但似乎无法在我的页面上找到它......所以这就是为什么我问。如何从mysql检索html制动器
我正在尝试为网页制作图片上传脚本,允许某人上传带有描述信息的网页。到目前为止,我得到了上传好,它被存储到数据库并显示,但我遇到的问题是,从文本从textarea不会显示刹车时,从mysql的数据retreiving ...
怎么可以我解决这个问题?
这是upload.php的
<?php
// Start a session for error reporting
session_start();
// Call our connection file
require("includes/conn.php");
// Check to see if the type of file uploaded is a valid image type
function is_valid_type($file)
{
// This is an array that holds all the valid image MIME types
$valid_types = array("image/jpg", "image/jpeg", "image/bmp", "image/gif");
if (in_array($file['type'], $valid_types))
return 1;
return 0;
}
// Just a short function that prints out the contents of an array in a manner that's easy to read
// I used this function during debugging but it serves no purpose at run time for this example
function showContents($array)
{
echo "<pre>";
print_r($array);
echo "</pre>";
}
// Set some constants
// This variable is the path to the image folder where all the images are going to be stored
// Note that there is a trailing forward slash
$TARGET_PATH = "content/uploads/";
// Get our POSTed variables
$fname = $_POST['fname'];
$lname = $_POST['lname'];
$image = $_FILES['image'];
// Sanitize our inputs
$fname = mysql_real_escape_string($fname);
$lname = mysql_real_escape_string($lname);
$image['name'] = mysql_real_escape_string($image['name']);
// Build our target path full string. This is where the file will be moved do
// i.e. images/picture.jpg
$TARGET_PATH .= $image['name'];
// Make sure all the fields from the form have inputs
if ($fname == "" || $lname == "" || $image['name'] == "")
{
$_SESSION['error'] = "All fields are required";
header("Location: index.php");
exit;
}
// Check to make sure that our file is actually an image
// You check the file type instead of the extension because the extension can easily be faked
if (!is_valid_type($image))
{
$_SESSION['error'] = "You must upload a jpeg, gif, or bmp";
header("Location: index.php");
exit;
}
// Here we check to see if a file with that name already exists
// You could get past filename problems by appending a timestamp to the filename and then continuing
if (file_exists($TARGET_PATH))
{
$_SESSION['error'] = "A file with that name already exists";
header("Location: index.php");
exit;
}
// Lets attempt to move the file from its temporary directory to its new home
if (move_uploaded_file($image['tmp_name'], $TARGET_PATH))
{
// NOTE: This is where a lot of people make mistakes.
// We are *not* putting the image into the database; we are putting a reference to the file's location on the server
$sql = "insert into people (fname, lname, filename) values ('$fname', '$lname', '" . $image['name'] . "')";
$result = mysql_query($sql) or die ("Could not insert data into DB: " . mysql_error());
header("Location: images.php");
exit;
}
else
{
// A common cause of file moving failures is because of bad permissions on the directory attempting to be written to
// Make sure you chmod the directory to be writeable
$_SESSION['error'] = "Could not upload file. Check read/write persmissions on the directory";
header("Location: index.php");
exit;
}
?>
,这是一个需要时进入textarea的显示与详细描述和刹车的图像的PHP:
<?php
// Get our database connector
require("includes/conn.php");
?>

<body>
<div>
<?php
// Grab the data from our people table
$sql = "select * from people";
$result = mysql_query($sql) or die ("Could not access DB: " . mysql_error());
while ($row = mysql_fetch_assoc($result))
{
echo "<div class=\"picture\">";
echo "<p>";
// Note that we are building our src string using the filename from the database
echo "<img src=\"content/uploads/" . $row['filename'] . "\" alt=\"\" /><br />";
echo $row['fname'] . " " . "<br />" . "<br />" . $row['lname'] . "<br />";
echo "</p>";
echo "</div>";
\t \t \t \t }
?>
</div>
</body>
</html>
和certenty,这是一个让你输入的详细描述,并上传的图片中的index.php:
<?php
// Start a session for displaying any form errors
session_start();
?>

"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

</style>
</head>
<body>
<div>
<?php
if (isset($_SESSION['error']))
{
echo "<span id=\"error\"><p>" . $_SESSION['error'] . "</p></span>";
unset($_SESSION['error']);
}
?>

我试着像使用和nl2br但是没有什么几件事情似乎工作(可能是因为我错误地使用它...)
完美地工作,所以这一定是为什么我没有得到它的工作,我认为它需要改变在images.php因为这是我的输出,从来没有想过我上传错了...谢谢很多! – FGOD 2014-11-06 08:04:40
我确实有一些跟进问题,但这些与制动器的东西无关:所以我想我最好提出一个新的问题;)因为我仍然需要在我的布局中实现这一点,出于某种原因,它拧紧了布局我的页面 – FGOD 2014-11-06 08:06:03
没关系,刚发现问题,忘记上传css对布局没有多大帮助:p – FGOD 2014-11-06 08:13:15
