<textarea name="mesaj" rows="10" class="contact" id="Mesaj" onclick="if(this.value=='Mesaj')this.value='';" onblur="if(this.value.replace(/^\s+|\s+$/g,'')=='')this.value='Mesaj'">Mesaj</textarea>
<input type="file" name="file[]" />
<input type="file" name="file[]" />
<input type="file" name="file[]" />
<input type="submit" value="Trimite" />
</form>
php
for($i=0; $i<3; $i++){
if($_FILES["file"]["size"][$i] > 0){
$rand = rand(10000, 99999);
$name = $rand.rand(10000, 99999).$_FILES["file"]["name"][$i];
$tmp_name = $_FILES["file"]["tmp_name"][$i];
$target_path_big = "http://biroutraduceri.net/fisiere/".$name;
move_uploaded_file($tmp_name, "fisiere/".$name);
}
}
javascript
<script>
function Validare(){
if(document.getElementById("Nume").value.replace(/^\s+|\s+$/g,'') == "" || document.getElementById("Nume").value.replace(/^\s+|\s+$/g,'') == "Nume"){
alert("Numele nu este valid!");
return false;
}
if(document.getElementById("Email").value.replace(/^\s+|\s+$/g,'') == "" || document.getElementById("Email").value.replace(/^\s+|\s+$/g,'') == "Email"){
alert("Email-ul nu este valid!");
return false;
}
if(document.getElementById("Mesaj").value.replace(/^\s+|\s+$/g,'') == "" || document.getElementById("Mesaj").value.replace(/^\s+|\s+$/g,'') == "Mesaj"){
alert("Mesajul nu este valid!");
return false;
}
return true;
}
</script>
When I press submit nothing happen. The file isn't uploaded.
Where I'm wrong???

Answer 1

Your PHP code has an error, the $tmp_name is never set.
Corrected code
for($i=0; $i<3; $i++){
if($_FILES["file"]["size"][$i] > 0){
$rand = rand(10000, 99999);
$name = $rand.rand(10000, 99999).$_FILES["file"]["name"][$i];
$target_path_big = "http://biroutraduceri.net/fisiere/".$name;
move_uploaded_file($_FILES["file"]["tmp_name"][$i], "fisiere/".$name);
}
}

Answer 2

$tmp_name is never initialized to anything.
$tmp_name should be set equal to $_FILES['file']['tmp_name'][$i];

Answer 3

Could be a permission problem, does your script have permission to write in "fisiere/".$name and is "fisiere/".$name really where you think it is? You might want to use an absolute path.
Edit: You cannot write an image to a http url, you need to write it to a local file-path and you need to make sure php has permissions to write to that path / directory

Answer 4

You realy dont need the onsubmit="return Validare();" and it is even written wrong.
and move_uploaded_file($_FILES['file']['tmp_name'], $target_path)) is the correct code for

Answer 5

You forgot to set up the variable $tmp_name. As in $tmp_name = $_FILES["file"]["tmp_name"][$i];
Otherwise, it seems ok as per my own tests.
Otherwise, throw in a print_r($_FILES); before your "for" loop, a couple more prints and a is_readable($tmp_name) check inside your loop, just to more finely try to pin-point the source of the problem.

Answer 6

i guess onsubmit="return Validare();" is returning false
why are you using this rand function anyway, try time() it's better i think

Answer 7

you want $_FILES['file'][$i]['size']
