我有这个代码
<div class="item1">
<form action="" method="post" enctype="multipart/form-data">
<label>White</label>
<input type="file" name="files[]" multiple="multiple" accept="image/*">
<label>Black</label>
<input type="file" name="files[]" multiple="multiple" accept="image/*">
<label>Red</label>
<input type="file" name="files[]" multiple="multiple" accept="image/*">
<input type="submit" value="Upload">
</form>
</div>
我想要这样的php，但我不知道如何设置它
$namewhite = $_FILES['photoimg']['name'][white];
$sizewhite = $_FILES['photoimg']['size'][white];
$nameblack = $_FILES['photoimg']['name'][black];
$sizeblack = $_FILES['photoimg']['size'][black];
$namered = $_FILES['photoimg']['name'][red];
$sizered = $_FILES['photoimg']['size'][red];
$path1 = "white/";
$path2 = "black/";
$path3 = "red/";
if(move_uploaded_file($tmp, $path1.$actual_image_name1))
if(move_uploaded_file($tmp, $path2.$actual_image_name2))
if(move_uploaded_file($tmp, $path3.$actual_image_name3))
$query = "INSERT INTO upload_image (id_item, color, url)VALUES('$id_item', '$color', '$url')";
$result8 = $mysqli->query($query);
因此，如果我以红色上传图像，图像将保存在红色文件夹。 如果以白色上传，将保存在白色文件夹。我不想分开，我想使用一个按钮，因为这个图像会根据数据项保存。并且数据将存储在MySQL中，取决于颜色。因为如果我用于($i = 0; $i < count ($_FILES['files']['name']); $i++)我不明白如何按颜色将它们分开。
如果我们想象，我想包括照片NIKIPredator鞋，那么有黑色，红色和白色三种颜色。所以我上传照片，但图像，与存储分开。可以吗？
编辑我像这样使用 php
<?php
if (isset($_POST['submit'])){
for($i=0;$i<4;$i++){
echo "<b>File".($i+1).".</b><br>";
if ((($_FILES["userfile"]["type"][$i] == "image/gif")
|| ($_FILES["userfile"]["type"][$i] == "image/jpeg")
|| ($_FILES["userfile"]["type"][$i] == "image/pjpeg"))
&& ($_FILES["userfile"]["size"][$i] < 100000))
{
if ($_FILES["userfile"]["error"][$i] > 0)
{
echo "File Error : " . $_FILES["userfile"]["error"][$i] . "<br />";
}else {
if (file_exists("images/".$_FILES["userfile"]["name"][$i]))
{
echo "<b>".$_FILES["userfile"]["name"][$i] . " already exists. </b>";
}else
{
move_uploaded_file($_FILES["userfile"]["tmp_name"][$i],"images/". $_FILES["userfile"]["name"][$i]);
echo "Stored in: " . "images/" . $_FILES["userfile"]["name"][$i]."<br />";
?>
Uploaded File:<br>
<img src="images/<?php echo $_FILES["userfile"]["name"][$i]; ?>" width="100"
height="100" alt="Image path Invalid" >
<?php
}
}
}else
{
echo "Invalid file detail<br> file type ::".$_FILES["userfile"]["type"][$i]." , file size::: ".$_FILES["userfile"]["size"][$i];
}
echo "<br>";
}
}else{
echo "File details not avaliable.";
}
?>
像这样的HTML
<form action="multiple_file_upload.php" method="post" onSubmit="return validate()"
enctype="multipart/form-data" >
<table align="center" >
<tr>
<td><label for="file1">File 1:</label></td>
<td><input name="userfile[]" type="file" id="file" /></td>
</tr>
<tr>
<td><label for="file2">File 2:</label></td>
<td><input name="userfile[]" type="file" /></td>
</tr>
<tr>
<td><label for="fil3">File 3:</label></td>
<td><input name="userfile[]" type="file" /></td>
</tr>
<tr>
<td><label for="file4">File 4:</label></td>
<td><input name="userfile[]" type="file" /></td>
</tr>
<tr>
<td></td>
<td><input type="submit" name="submit" value="Submit" /></td>
</tr>
<table>
</form>
为此，我们需要区分input。
<div class="item1">
<form action="" method="post" enctype="multipart/form-data">
<label>White</label>
<!-- Changed name to 'white' -->
<input type="file" name="white[]" multiple="multiple" accept="image/*">
<label>Black</label>
<!-- Changed name to 'black' -->
<input type="file" name="black[]" multiple="multiple" accept="image/*">
<label>Red</label>
<!-- Changed name to 'red' -->
<input type="file" name="red[]" multiple="multiple" accept="image/*">
<input type="submit" value="Upload">
</form>
</div>
如果用户通过white input上传，$_FILES['white']、$_FILES['white']['name']和$_FILES['white']['size']将被初始化。
我们可以转动以下伪代码：
$namewhite = $_FILES['photoimg']['name'][white];
$sizewhite = $_FILES['photoimg']['size'][white];
$nameblack = $_FILES['photoimg']['name'][black];
$sizeblack = $_FILES['photoimg']['size'][black];
$namered = $_FILES['photoimg']['name'][red];
$sizered = $_FILES['photoimg']['size'][red];
到：
if (isset($_FILES['white'])) {
$namewhite = $_FILES['white']['name'];
$sizewhite = $_FILES['white']['size'];
}
if (isset($_FILES['black'])) {
$nameblack = $_FILES['black']['name'];
$sizeblack = $_FILES['black']['size'];
}
if (isset($_FILES['red'])) {
$redblack = $_FILES['red']['name'];
$redblack = $_FILES['red']['size'];
}
我会让你弄清楚如何将各种文件保存在各自的目录中。 在使用变量之前，请务必小心确保已定义变量。
我还没有测试上面的代码。 请原谅任何错误。
