一种形式中的多个图像输入？

Question

我看到的大多数问题都与一张图像输入有关。但是，如果您有 2 个或 3 个或更多怎么办？

我的一个图像输入脚本有效，但我试图在我的表单中输入一个单图像和一个多图像输入。我正在测试在我的表单上输入 2 个单图像但无法正常工作。

这是一个单图像输入的 HTML（假设它在 < form > 标签内）：

  <input type="hidden" name="size" value="350000"/>
  <input type="file" name="schoollogo"/><br/>

PHP:

  $target = "images/logo/";
  $target = $target . basename( $_FILES['schoollogo']['name']);

  $schoollogo = $_FILES['schoollogo']['name'];

  //Writes the information to the database

  mysql_query("INSERT INTO Colleges (schoollogo) VALUES ('$schoollogo')") or die(mysql_error()) ;

  //Writes the logo to the server
  if (move_uploaded_file($_FILES['schoollogo']['tmp_name'], $target)) {
      //Tells you if its all ok
      echo "The file ". basename( $_FILES['uploadedfile']['name']). " has been uploaded, and your information has been added to the directory";
  } else {
      //Gives and error if its not
      echo "Sorry, there was a problem uploading your file.";
  }

对于第二个单图输入，我只是添加了第二个输入代码...

 <input type="hidden" name="size" value="350000"/>
 <input type="file" name="otherimage"/><br/>

然后将变量添加到PHP:

  $targetotherimage = "images/otherimage/";
  $targetotherimage = $targetotherimage . basename( $_FILES['otherimage']['name']);

  mysql_query("INSERT INTO Colleges (schoollogo,otherimage) VALUES ('$schoollogo','$otherimage')") or die(mysql_error()) ;

  //Writes the logo to the server
  if (move_uploaded_file($_FILES['schoollogo']['tmp_name'], $target)) && (move_uploaded_file($_FILES['otherimage']['tmp_name'], $targetotherimage)) {

但是当将该代码添加到 PHP 时，该代码不起作用。没有错误消息或任何东西。页面是空白的。

顺便说一下，here is my other question 我正在尝试将一个多图像上传输入添加到我的表单中，该输入已经可以正常工作了。

Answer 1

if 条件关闭错误。

  if(move_uploaded_file($_FILES['schoollogo']['tmp_name'], $target)) && (move_uploaded_file($_FILES['otherimage']['tmp_name'], $targetotherimage)) {
                                                                  ^^^^// In your code if condition close here

用作

  if(move_uploaded_file($_FILES['schoollogo']['tmp_name'], $target) 

&& (move_uploaded_file($_FILES['otherimage']['tmp_name'],  $targetotherimage)))//if condition close here 
{
// rest of code

}

这对你有用，用这个替换你的表格

<form method="post" enctype="multipart/form-data" action="upload.php">
      <input type="file" name="file['schoollogo']" >
      <input type="file" name="file['otherimage']" >
      <input type="submit" value="submit">
</form>

您将获得以下格式的文件：

Array
(
    [file] => Array
        (
            [name] => Array
                (
                    ['schoollogo'] => 1465386599_Location_Outline-36.png
                    ['otherimage'] => STONE_Website_v7E.jpg
                )

            [type] => Array
                (
                    ['schoollogo'] => image/png
                    ['otherimage'] => image/jpeg
                )
        ) 
)

并在 upload.php 文件中

<?php 
if (isset($_FILES['file'])) 
{
     $schoollogo=$_FILES['file']['name']['schoollogo'];
     $target = "images/logo/".basename($schoollogo);;

     $otherimage = $_FILES['file']['name']['otherimage'];
     $targetotherimage = "images/otherimage/".basename($otherimage);

      $tmp_name_school = $_FILES['file']['tmp_name']['schoollogo'];
      $tmp_name_other = $_FILES['file']['tmp_name']['otherimage'];

      if ($tmp_name_school != "" && $tmp_name_other !== "")
      {
        //Upload the file 
        if(move_uploaded_file($tmp_name_school,$target) && move_uploaded_file($tmp_name_other, $targetotherimage)) 
        {
          mysql_query("INSERT INTO Colleges (schoollogo,otherimage) VALUES ('$schoollogo','$otherimage')") or die(mysql_error()) ;
          echo'Done!';
        }
        else
        {
            echo "Not Moved";
        }
      }
}   
?>
