如果我这样做,我无法显示缩略图:

echo "<img width='300'height='300' src='images/".$row['image']."' alt='Profile Picture'>";

显示图片:

但是当我这样做时它不起作用

profile.php

<?php 
require_once('includes/config.inc.php'); 
require_once('includes/functions.inc.php');
include("includes/html_codes.php");
session_start();

$username = $_SESSION["username"];

if ($_SESSION['logged_in'] == false) { 
              // If user is already logged in, redirect to main page 
              redirect('lo.php');
}
?>

<?php

    if(isset($_POST['submit'])){
    $temporary_name=$_FILES['file']['tmp_name'];
        move_uploaded_file($_FILES['file']['tmp_name'],"images/".$_FILES['file']['name']);
         $mysqli = new mysqli(DB_HOSTNAME, DB_USERNAME, DB_PASSWORD, DB_DATABASE); 
         $q = mysqli_query($mysqli,"UPDATE users SET image = '".$_FILES['file']['name']."'WHERE username = '".$_SESSION['username']."'");
         }

?>

        <form action="" method="post" enctype="multipart/form-data">
            <input type="file" name="file">
            <input type="submit" name="submit">
        </form>
<?php 

$mysqli = new mysqli(DB_HOSTNAME, DB_USERNAME, DB_PASSWORD, DB_DATABASE);
            $q = mysqli_query($mysqli,"SELECT * FROM users WHERE username = '$username'");
            $row = mysqli_fetch_assoc($q);

$width= 275;
$height= 275;
$orig_image = imagecreatefromjpeg("'images/".$row['image']."'");
if (imagesx($orig_image) > imagesy($orig_image)) {
  $y = 0;
  $x = (imagesx($orig_image) - imagesy($orig_image)) / 2;
  $smallestSide = imagesy($orig_image);
}
 else {
  $x = 0;
  $y = (imagesy($orig_image) - imagesx($orig_image)) / 2;
  $smallestSide = imagesx($orig_image);
} 


$image_p = imagecreatetruecolor($width, $height);



Imagecopyresampled($image_p,$orig_image,0,0,$x,$y,$width,$height,$smallestSide,$smallestSide);


?> 

它给了我这些错误帮助!

1 个答案:

答案 0 :(得分:3)

这一行错了:

$orig_image = imagecreatefromjpeg("'images/".$row['image']."'");

你在你的图像周围加上单引号,所以php实际上是在寻找目录'images和你的文件名,最后是引号。

应该是:

$orig_image = imagecreatefromjpeg("images/".$row['image']);

由于图像未成功创建,因此需要图像的所有行都会发出警告。
