上传多个图像到数据库使用PHP

Question

这是我的形式（在底部图像输入）：

<form class="pure-form pure-form-stacked" action="propsubmit.php" method="post" name="uploadproperty" enctype="multipart/form-data" style="margin-left: 20px; color:black"> 
    <fieldset><br> 

     <label for="propertyname" class="button button-alt" style="background-color:white" >Property Name:</label> 
     <input id="propertyname" name="propertyname" type="text" placeholder="Enter name here.... " size="50" required="required"/><br> 

     <label for="description" class="button button-alt" style="background-color:white "> Description:</label> 
     <textarea rows="10" cols="100" name="description" placeholder="Enter description here...." required="required"></textarea><br>  

     <label for="county" class="button button-alt" style="background-color:white">County:</label> 
     <select id="county" name="county" placeholder="Choose County" required="required"> 
      <?php 

      if(mysqli_num_rows($result) > 0){ 
       while($row = mysqli_fetch_assoc($result)){ 
        $countyid = $row["ID"]; 
        $countyname = $row["County"]; 

        echo "<option value='$countyid'>$countyname</option>"; 
       } 
      } 

      ?> 
     </select> 

     <label for="amin" class="button button-alt" style="background-color:white" >Autumn minimum price:</label> 
     <input id="amin" name="amin" type="text" placeholder="Price.... " size="10" required="required"/><br> 

     <label for="amax" class="button button-alt" style="background-color:white" >Autunm maximum price:</label> 
     <input id="amax" name="amax" type="text" placeholder="Price.... " size="10" required="required"/><br> 

     <label for="spmin" class="button button-alt" style="background-color:white" >Spring minimum price:</label> 
     <input id="spmin" name="spmin" type="text" placeholder="Price.... " size="10" required="required"/><br> 

     <label for="spmax" class="button button-alt" style="background-color:white" >Spring maximum price:</label> 
     <input id="spmax" name="spmax" type="text" placeholder="Price.... " size="10" required="required"/><br> 

     <label for="sumin" class="button button-alt" style="background-color:white" >Summer minimum price:</label> 
     <input id="sumin" name="sumin" type="text" placeholder="Price.... " size="10" required="required"/><br> 

     <label for="sumax" class="button button-alt" style="background-color:white" >Summer maximum price:</label> 
     <input id="sumax" name="sumax" type="text" placeholder="Price.... " size="10" required="required"/><br> 

     <label for="wmin" class="button button-alt" style="background-color:white" >Winter minimum price:</label> 
     <input id="wmin" name="wmin" type="text" placeholder="Price.... " size="10" required="required"/><br> 

     <label for="wmax" class="button button-alt" style="background-color:white" >Winter maximum price:</label> 
     <input id="wmax" name="wmax" type="text" placeholder="Price.... " size="10" required="required"/><br>  

     <label for="propimgs" class="button button-alt" style="background-color:white">Images:</label> 
     <input name="propimgs[]" type="file" multiple="" /><br> 

这是在我的进程页的图像中的代码：

$ imagecount =计数（ $ _FILES [ 'propimgs'] [ '名称']）;

if ($total>0){ 

    for ($i=0; $i<$total; $i++){ 

     //current file location 
     $temppath = $_FILES['propimgs']['tmp_name'][$i]; 


     //prevents file names duplicates 
     $rand= rand(); 

     //moving file to img folder. adds $rand to file name 
     $newpath = "../images/".$rand.$_FILES['propimgs']['name'][$i]; 

     //file name in db 
     $sourcename = $rand.$_FILES['propimgs']['name'][$i]; 

     move_uploaded_file($temppath, $newpath); 


$insertquery3 = "INSERT INTO Image (Property_ID, Path) VALUES ('$pid', '$sourcename')"; 


$result3 = mysqli_query($conn, $insertquery3) or die(mysqli_error($conn)); 

    } 

} 

当我尝试上传时，属性上传除了图像。它说“总”变量是未定义的。你知道这是为什么吗？谢谢。

$total在您调用它之前未初始化。尝试if ($total>0){...前加入这一行$total = count($_FILES['propimgs']['name']);
