大家好，我希望有人可以帮助我，我对网站设计，php之类的东西还很陌生，几个月前我就已经开始工作了，但是我忘记了我所做的事情，我敢肯定，这是一个小错误，但是我一次又一次地阅读了代码后，尝试了一些事情。
这是我用来通过表单解析图像的代码，表单本身正在运行，因此我认为它必须位于我添加的用于处理图像的文件中。
add.php：
public void animFab() {
ObjectAnimator scaleX = ObjectAnimator.ofFloat(fab, View.SCALE_X, from, to);
ObjectAnimator scaleY = ObjectAnimator.ofFloat(fab, View.SCALE_Y, from, to);
AnimatorSet set1 = new AnimatorSet();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
ObjectAnimator translationZ = ObjectAnimator.ofFloat(fab, View.TRANSLATION_Z, from, to);
set1.playTogether(scaleX, scaleY, translationZ);
} else {
set1.playTogether(scaleX, scaleY);
}
set1.setDuration(500);
set1.setInterpolator(new AccelerateInterpolator());
set1.addListener(new AnimatorListenerAdapter() {
@Override
public void onAnimationEnd(Animator animation) {
}
});
Path path = new Path();
path.moveTo(0.0f, 0.0f);
path.lineTo(0.5f, 1.3f);
path.lineTo(0.75f, 0.8f);
path.lineTo(1.0f, 1.0f);
Interpolator pathInterpolator = PathInterpolatorCompat.create(path);
AnimatorSet set2 = new AnimatorSet();
ObjectAnimator scaleXBack = ObjectAnimator.ofFloat(fab, View.SCALE_X, to, from);
ObjectAnimator scaleYBack = ObjectAnimator.ofFloat(fab, View.SCALE_Y, to, from);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
ObjectAnimator translationZBack = ObjectAnimator.ofFloat(fab, View.TRANSLATION_Z, to, from);
set2.playTogether(scaleXBack, scaleYBack, translationZBack);
} else {
set2.playTogether(scaleXBack, scaleYBack);
}
set2.setDuration(500);
set2.setInterpolator(pathInterpolator);
final AnimatorSet set = new AnimatorSet();
set.playSequentially(set1, set2);
set.addListener(new AnimatorListenerAdapter() {
@Override
public void onAnimationEnd(Animator animation) {
super.onAnimationEnd(animation);
set.start();
}
});
set.start();
}
然后我正在使用的SimpleImage php：
$target1 = "/upload dir/";
$target = $target1 . basename( $_FILES['photo']['name']);
$target21 = "/upload dir/";
$target2 = $target21 . basename( $_FILES['photo2']['name']);
$target31 = "/upload dir/";
$target3 = $target31 . basename( $_FILES['photo3']['name']);
$target41 = "/upload dir/";
$target4 = $target41 . basename( $_FILES['photo4']['name']);
$target51 = "/upload dir/";
$target5 = $target51 . basename( $_FILES['photo5']['name']);
$target61 = "/upload dir/";
$target6 = $target61 . basename( $_FILES['photo6']['name']);
$target71 = "/upload dir/";
$target7 = $target71 . basename( $_FILES['photo7']['name']);
$target81 = "/upload dir/";
$target8 = $target81 . basename( $_FILES['photo8']['name']);
$target91 = "/upload dir/";
$target9 = $target91 . basename( $_FILES['photo9']['name']);
$target101 = "/upload dir/";
$target10 = $target101 . basename( $_FILES['photo10']['name']);
//lots of other code.**
$con=mysqli_init();
if (!$con)
{
die("mysqli_init failed");

if (!mysqli_query($con,$sql))
{

}
else {
echo "1 record added";
}
function store_uploaded_image($html_element_name, $new_img_width,
$new_img_height) {
$target_dir = "/upload dir/";
$target_file = $target_dir . basename($_FILES[$html_element_name]["name"]);
$image = new SimpleImage();
$image->load($_FILES[$html_element_name]['name']);
$image->resize($new_img_width, $new_img_height);
$image->save($target_file);
return $target_file; //return name of saved file in case you want to store
it in you database or show confirmation message to user
}
echo "<table>";
store_uploaded_image($pic, 600, 450);
//Writes the photo to the server
if(move_uploaded_file($_FILES['photo']['tmp_name'], $target))
{ //Tells you if its all ok
echo "<tr width='600' height='50' halign='center' valign='center'><td>";
echo "The file ". basename( $_FILES['uploadedfile']['name']). " has been
uploaded, and your information has been added to the directory";
echo "</td></tr>";
}
else {
echo "<tr width='600' height='50' halign='center' valign='center'><td>";
//Gives and error if its not
echo "Sorry, there was a problem uploading your file.";
echo "</td></tr>";
}
/10 more of these for 10 images**
检查add.php源代码时出现的错误：

我的表单用于上传图像，然后将其添加到add.php中，图像名称保存在数据库中，图像存储在目录中，但是不知何故跳过了调整大小的过程。
