Question

我在项目中的图片中有一个默认图像，但似乎无法在用户没有上传图像时反映出来。请帮忙。下面是个人资料视图以及上传脚本

Profile.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>

upload.php的

<?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>

";

?>

Answer 1

我通常这样做

<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。

如何设置默认默认图像（no_pic.gif）php？
