将多个图像文件上传到php mysql库

2019-07-25 14:24:27 作者：互联网

我得到了这个厨房约占我想要它的65％.我想知道是否有人可以查看以下代码并告诉我如何将多个图像上传到我的图库.

这是代码.

简单的管理表单代码：

    <form enctype="multipart/form-data" action="uploader.php" method="POST">


        Category: <select class="text" name="dataType[]">
        <option value="treeremoval" selected="selected">treeremoval</option>
        <option value="treetrimming" >treetrimming</option>
        <option value="treebracing" >treebracing</option>
        <option value="stumpgrinding" >stumpgrinding</option>
        <option value="firewood" >firewood</option>
        <option value="cleanup" >cleanup</option>
        </select>
<br /><br />

    Caption: <input type="text" name="title[]">
<br /><br />

Image to upload: <input type="file" name="image[]" />
<br /><br />






        Category: <select class="text" name="dataType[]">
        <option value="treeremoval" selected="selected">treeremoval</option>
        <option value="treetrimming" >treetrimming</option>
        <option value="treebracing" >treebracing</option>
        <option value="stumpgrinding" >stumpgrinding</option>
        <option value="firewood" >firewood</option>
        <option value="cleanup" >cleanup</option>
        </select>
<br /><br />

    Caption: <input type="text" name="title[]">
<br /><br />

Image to upload: <input type="file" name="image[]" />
<br /><br />



    <input type="submit" value="Upload">
</form>

uploader.php代码：

    <?php
include($_SERVER['DOCUMENT_ROOT'] . "/connections/dbconnect.php");

$dataType = mysql_real_escape_string($_POST["dataType"][$i]);
$title = mysql_real_escape_string($_POST["title"][$i]);

$fileData = pathinfo(basename($_FILES["image"]["name"][$i]));

$fileName = uniqid() . '.' . $fileData['extension'][$i];

$target_path = ($_SERVER['DOCUMENT_ROOT'] . "/images/gallery/" . $fileName);


for($i=0;$i<count($_FILES["image"]["name"]);$i++){

 $dataType = mysql_real_escape_string($_POST["dataType"][$i]);  // get the dataType with the same key - $i
    $title = mysql_real_escape_string($_POST["title"][$i]);   // get the title with the same key - $i

    $fileData = pathinfo(basename($_FILES["image"]["name"][$i]));
while(file_exists($target_path))
{
    $fileName = uniqid() . '.' . $fileData['extension'];
    $target_path = ($_SERVER['DOCUMENT_ROOT'] . "/images/gallery/" . $fileName);
}

 if (move_uploaded_file($_FILES["image"]["tmp_name"][$i], $target_path))
    {    // The file is in the images/gallery folder. Insert record into database by
    // executing the following query:
     $sql="INSERT INTO images (data_type, title, file_name)"."VALUES('$dataType','$title','$fileName')";
     $retval = mysql_query($sql);



echo "The image {$_FILES['image']['name'][$i]} was successfully uploaded and added to the gallery<br />
     <a href='index.php'>Add another image</a><br />";


}
else
{
 echo "There was an error uploading the file {$_FILES['image']['name'][$i]}, please try again!<br />";
    }
} // close your foreach
?>

我尝试重复4次表单代码,但它只会将1张图片上传到图库.

任何帮助将不胜感激.

谢谢！

解决方法:

在表单中,添加多个文件输入.一种方法是使用数组名称 – image []

Image to upload: <input type="file" name="image[]" /><br />
Image to upload: <input type="file" name="image[]" /><br />
Image to upload: <input type="file" name="image[]" /><br />
....  // as many as you want. Just be aware of upload_max_filesize, memory_limit, post_max_size etc.
<br />

然后在你的uploader.php中,用for循环包装你的文件上传代码

for($i=0;$i<count($_FILES["image"]["name"]);$i++){

    $fileData = pathinfo(basename($_FILES["image"]["name"][$i]));

     ...

    if (move_uploaded_file($_FILES["image"]["tmp_name"][$i], $target_path))
    {
      ...

      echo "The image {$_FILES['image']['name'][$i]} was successfully uploaded and added to the gallery<br />";

    }
    else
    {
     echo "There was an error uploading the file {$_FILES['image']['name'][$i]}, please try again!<br />";
    }
} // close your foreach

手册有很多关于上传文件时常见陷阱的部分,特别是多个. http://www.php.net/manual/en/features.file-upload.common-pitfalls.php

如果你想做其他的多个,可以用同样的方式完成(我缩写选择以减少复制/粘贴) –

<form enctype="multipart/form-data" action="uploader.php" method="POST">

    // 1st set
    Category: <select class="text" name="dataType[]" />
    ...
    </select><br />
    <br />        

    Caption: <input type="text" name="title[]" /><br />
    <br />

    Image to upload: <input type="file" name="image[]" /><br />
    <br /> 

    // 2nd set
    Category: <select class="text" name="dataType[]" />
    ...
    </select><br />
    <br />        

    Caption: <input type="text" name="title[]" /><br />
    <br />

    Image to upload: <input type="file" name="image[]" /><br />
    <br />  

   // and so on, as many as you want  
   ...
    <input type="submit" value="Upload">
</form>

和你的PHP,围绕所有元素的for循环

for($i=0;$i<count($_FILES["image"]["name"]);$i++){

    $dataType = mysql_real_escape_string($_POST["dataType"][$i]);  // get the dataType with the same key - $i
    $title = mysql_real_escape_string($_POST["title"][$i]);   // get the title with the same key - $i

    $fileData = pathinfo(basename($_FILES["image"]["name"][$i]));

     ...

    if (move_uploaded_file($_FILES["image"]["tmp_name"][$i], $target_path))
    {
      ...

      echo "The image {$_FILES['image']['name'][$i]} was successfully uploaded and added to the gallery<br />";

    }
    else
    {
     echo "There was an error uploading the file {$_FILES['image']['name'][$i]}, please try again!<br />";
    }
} // close your foreach

编辑
你快到了.删除for循环上方的重复代码.删除basename(),因为这会导致扩展失败,而pathinfo()将返回[‘basename’].

<?php
include($_SERVER['DOCUMENT_ROOT'] . "/connections/dbconnect.php");

for($i=0;$i<count($_FILES["image"]["name"]);$i++){
  if($_FILES["image"]["name"][$i] != ''){ // don't insert if file name empty
    $dataType = mysql_real_escape_string($_POST["dataType"][$i]);
    $title = mysql_real_escape_string($_POST["title"][$i]);

    $fileData = pathinfo($_FILES["image"]["name"][$i]);

    $fileName = uniqid() . '.' . $fileData['extension'];
    $target_path = $_SERVER['DOCUMENT_ROOT'] . "/images/gallery/" . $fileName;

    while(file_exists($target_path)){
       $fileName = uniqid() . '.' . $fileData['extension'];
       $target_path = $_SERVER['DOCUMENT_ROOT'] . "/images/gallery/" . $fileName;
    }     

  if (move_uploaded_file($_FILES["image"]["tmp_name"][$i], $target_path)){    // The file is in the images/gallery folder. 
    // Insert record into database by executing the following query:
     $sql="INSERT INTO images (data_type, title, file_name) "."VALUES('$dataType','$title','$fileName')";
     $retval = mysql_query($sql);

    echo "The image {$_FILES['image']['name'][$i]} was successfully uploaded and added to the gallery<br />
     <a href='index.php'>Add another image</a><br />";
  }
  else
  {
   echo "There was an error uploading the file {$_FILES['image']['name'][$i]}, please try again!<br />";
    }
  }
} // close your foreach
?>
