如何使圖像只上傳php

-1

你好，我想問一些關於我的代碼，我想過濾上傳的文件只是圖像，這個代碼是工作，但是當我上傳一部電影，它不斷上傳，並沒有執行條件我做了，任何人都可以修復它？感謝如何使圖像只上傳php

<?php 

    include "connect.php"; 

    $username = $_POST['username']; 
    $fullname = $_POST['fullname']; 
    $phone =$_POST['phone']; 
    $email = $_POST['email']; 
    $password = $_POST['password']; 
    $encryptPassword = md5($password); 
    $sex = $_POST['sex']; 
    $pict = $_FILES['pict']['name']; 

    $tmp = $_FILES['pict']['tmp_name']; 
    $newpict = date('dmYHis').$pict; 
    // Set path folder tempat menyimpan fotonya 
    $path = "../../CRUD/user/images/".$newpict; 
    $foto_size = $_FILES["pict"]["size"]; 
    $info = getimagesize($tmp); 

if ($info === FALSE) {?> 
    <script language="javascript">alert("Sign Up Failed");</script> 
    <script>document.location.href='daftar.php';</script><?php 

} 
if (($info[2] !== IMAGETYPE_GIF) && ($info[2] !== IMAGETYPE_JPEG) && ($info[2] !== IMAGETYPE_PNG)) {?> 
    <script language="javascript">alert("Sign Up Failed");</script> 
    <script>document.location.href='daftar.php';</script> 
    <?php 
} 
else{ 

if($foto_size < 1000000 && (strlen(trim($password))>=8)){ 
    if(move_uploaded_file($tmp, $path)){ 
     $sql_buat = "INSERT INTO user(id_user, username, fullname, email,phone, password, sex,user_picture) VALUE('','$username','$fullname','$email','$phone','$encryptPassword','$sex','$newpict')"; 

      if(isset($_POST['username'])&&($_POST['email'])) 
       { 
        $name=$_POST['username']; 
        $email=$_POST['email']; 
        $checkdata=" SELECT * FROM user WHERE email='$email' and username='$name' "; 
        $query=mysqli_query($conn,$checkdata); 
        if(mysqli_num_rows($query)>0) 
         {?>

          <script>document.location.href='daftar.php';</script><?php 
         } 
      } 
      if(isset($_POST['username'])) 
      { 
       $name=$_POST['username']; 
       $checkdata=" SELECT username FROM user WHERE username='$name' ";

      /*else 
       { 
        echo "OK"; 
       } 
      exit(); 
     }*/ 
      }

      if (mysqli_query($conn, $sql_buat)){ 
?> 
       <script language="javascript">alert("Sign up Successful");</script> 
       <script>document.location.href='../login/login.php';</script> 
      <?php

您正在檢查它是否是PHP上的圖像。 PHP只能在上傳後執行。在使用JavaScript發送表單之前做一些檢查。 –

你可以查看這個問題的建議：https://stackoverflow.com/questions/18299806/how-to-check-file-mime-type-with-javascript-before-upload –

md5不適合哈希密碼。而是使用：http://php.net/password_hash – Mike

在您的HTML5使用

<input type="file" name="myImage" accept="image/x-png,image/gif,image/jpeg" />

，並在你的PHP使用

 $ext_array = array("jpg", "gif", "png"); 
    $type = $_FILE['type']; 
    $temp = explode(".", $_FILE["name"]); 
    if(stristr($type, 'image') && in_array(end($temp), $ext_array)){ 
     move_uploaded_file($_FILE["tmp_name"], 'upload/' . 'newname.jpg') 
    }

全髖關節置換的總體思路。
