Вот код, который я сделал, я ожидаю, что он будет работать, но где-то должна быть ошибка. Я не могу понять себя, пожалуйста, помогите.
<?php
if(isset($_POST['submit'])){
$max_size = 500000;
$image_upload_path = "images/products/";
$allowed_image_extension = array('jpg','jpeg','png','gif');
for($i=0;$i<2;$i++)
{
//check if there is file
if((!empty($_FILES['image[]'][$i])) && ($_FILES['image[]']['error'][$i]==0))
{
//check extension
$extension = strrchr($_FILES['image']['name'][$i], '.');
if(in_array($extension,$allowed_image_extension))
{
//check file size.
if($_FILES['image']['size'][$i] > $max_size)
{
echo "file too big";
}
else if($_FILES['image']['size'][$i] < 1)
{
echo "file empty";
}
else
{
//we have pass file empty check,file extension check,file size check.
$the_uploaded_image = $_FILES['image']['tmp_name'][$i];
$the_uploaded_image_name = $_FILES['image']['name'][$i];
//replace empty space in filename with an underscore '_'
$the_uploaded_image_name = preg_replace('/\s/','_',$the_uploaded_image_name);
//get the file extension
$the_uploaded_image_extension = explode(',',$the_uploaded_image_name);
$the_new_image_name = $the_uploaded_image_name."".md5(uniqid(rand(),true))."".$the_uploaded_image_extension;
$save_image_as = $the_new_image_name;
//check file exist
if(file_exists($image_upload_path."".$the_new_image_name))
{
echo "file".$image_upload_path."".$the_new_image_name." already exist";
}
else
{
if(move_uploaded_file($the_uploaded_image,$save_image_as))
{
echo "image".$the_uploaded_image_name." uploaded sucessfully";
//set the image path to save in database column
}
else
{
echo "there was an error uploading your image.";
}
}
}
}
else
{
echo "extension not allowed";
}
}
else
{
echo "please choose file to upload";
}
}
}
?>

Это мой новый код PHP. Я получаю оба результата как найденный найденный не найденный не найденный. Кто-нибудь скажет мне, что я здесь делаю неправильно? Кажется, что условие if else не работает, так как оба условия дают выход. Почему?
<?php
if(isset($_POST["submit"])) {
echo $_POST["submit"];
echo "<br/>";
for($i=0;$i<count($_FILES['image'])-1;$i++)
{
if(!empty($_FILES['image']['tmp_name'][$i]))
{
echo "found";
echo "<br/>";
}
else
{
echo "not found";
echo "<br/>";
}
}
}
else
{
echo "form is not posted";
}
?>
