我在项目中的图片中有一个默认图像，但似乎无法在用户未上传图像时反射(reflect)出来。请帮助。下面是个人资料 View 和上传脚本
配置文件.php:
<head>
<title>Profile</title>
</head>
<body>
<table>
<tr>
<td colspan="2">View Your Current Profile</td>
</tr>
<tr>
<td>Title:</td>
<td><?php echo $jobseekertitle; ?></td>
</tr>
<tr>
<td>First Name:</td>
<td><?php echo $jobseekerfirstname; ?></td>
</tr>
<tr>
<td>Last Name:</td>
<td><?php echo $jobseekerlastname; ?></td>
</tr>
<tr>
<td>Address:</td>
<td><?php echo $jobseekeraddress; ?></td>
</tr>
<tr>
<td>Phone:</td>
<td><?php echo $jobseekerphoneno; ?></td>
</tr>
<tr>
<td>D.O.B (mm/dd/yyyy):</td>
<td><?php echo $jobseekerdob; ?></td>
</tr>
<tr>
<td>Gender:</td>
<td><?php echo $jobseekergender; ?></td>
</tr>
<tr>
<td>Picture:</td>
<td><?php echo "<img src='$location' width='100' height='100'>";?></td>
</tr>
</table>
<br><a href='upload.php'> Image upload</a>
<br><a href='resumecreator.php'> Resume information</a>
<br><a href='jobpreference.php'> Job Preference</a>
</body>
</html>
上传.php
<?php
// form in which we can upload the image
session_start();
include("connect.php");
// session as on website.
$jobseekerid = $_SESSION['jobseekerid'];
if($_POST['submit'])
{
//get file attributes
$name = $_FILES['myfile']['name'];
$tmp_name = $_FILES['myfile']['tmp_name'];
if ($name)
{
// start upload process
$location ="pictures/$name";
move_uploaded_file($tmp_name,$location);
// updating table users (setting image locaion
$query = mysql_query("UPDATE jobseekers SET imagelocation='$location' WHERE jobseekerid='$jobseekerid'");
die("Your avatar has been uploaded! <a href='profile.php'>Go back to view</a>");
}
else
die("Please Select a file!");
}
echo "Welcome, ".$_SESSION['username']."!<br><a href='logout.php'>Logout</a>";
echo "Upload Your image:
<form action='upload.php' method='POST' enctype='multipart/form-data'>
File: <input type='file' name='myfile'> <input type='submit' name='submit' value='upload!'
>
</form>
";
?>
最佳答案
我一般都是这样
<td><img src="<?= @$location ? $location : 'default/image.gif' ?>" width="100" height="100" /></td>
这样，如果 $location 不存在，它会抑制错误并输出默认替换。
