我可以上传1张图片并存储到mysql中，但如何上传和存储1张以上的图片，我想上传3张图片并存储到数据库中？ 这里我的代码是上传1张图片并存储到数据库：
在我的sql列名称上：kodem，tipe，images1，images2，images3
<!DOCTYPE html>
<?php
include("koneksi.php");
if(isset($_POST['Input'])) {
$Kode = $_POST['Kode'];
$Tipe = $_POST['Tipe'];
$file_name = $_FILES['images1']['name'];
$file_size = $_FILES['images1']['size'];
$file_tmp = $_FILES['images1']['tmp_name'];
$file_ext = strtolower(end(explode(".", $file_name)));
$ext_boleh = array("jpg", "jpeg", "png", "gif", "bmp");
if(in_array($file_ext, $ext_boleh)) {
$sumber = $file_tmp;
$tujuan = "images/" . $file_name;
move_uploaded_file($sumber, $tujuan);
$sql = "insert into database_latihan values ('$Kode' , '$Tipe' , '$tujuan')";
mysqli_query($koneksi, $sql);
}else {
echo "Only Images can be store!";
}
}
?>

答案 0 :(得分：3)
您可以添加3个输入
<td rowspan="1">
<input type="file" id="upload" name="images1[]">
</td>
<td rowspan="1">
<input type="file" id="upload" name="images1[]">
</td>
<td rowspan="1">
<input type="file" id="upload" name="images1[]">
</td>
或者让您的一个输入允许multiple输入
<td rowspan="1">
<input type="file" id="upload" multiple name="images1[]">
</td>
无论哪种方式，您都会得到一个$_FILES['images1']现在是一个数组
然后你的PHP代码只需要遍历$ _FILES数组
<?php
include("koneksi.php");
if(isset($_POST['Input'])) {
$Kode = $_POST['Kode'];
$Tipe = $_POST['Tipe'];
// you should really be checking for upload errors
foreach ($_FILES['images1']['error'] as $err) {
switch ($err) {
case UPLOAD_ERR_NO_FILE:
echo 'No file sent.';
exit;
case UPLOAD_ERR_INI_SIZE:
case UPLOAD_ERR_FORM_SIZE:
echo 'Exceeded filesize limit.';
exit;
}
}
for($x=0; $x<count($_FILES['images1']['tmp_name']); $x++ ) {
$file_name = $_FILES['images1']['name'][$x];
$file_size = $_FILES['images1']['size'][$x];
$file_tmp = $_FILES['images1']['tmp_name'][$x];
$t = explode(".", $file_name);
$t1 = end($t);
$file_ext = strtolower(end($t));
$ext_boleh = array("jpg", "jpeg", "png", "gif", "bmp");
if(in_array($file_ext, $ext_boleh)) {
$sumber = $file_tmp;
$tujuan = "images/" . $file_name;
move_uploaded_file($sumber, $tujuan);
$sql = "insert into database_latihan values ('$Kode' , '$Tipe' , '$tujuan')";
mysqli_query($koneksi, $sql);
}else {
echo "Only Images can be store!";
}
} // endfor
}
?>
