Why can't upload file pdf?

Question

this is html code:

 <form id="upload" action="upload.php" method="POST" enctype="multipart/form-data">
 <fieldset>
 <legend>html upload</legend>
 <input type="hidden" id="MAX_FILE_SIZE" name="MAX_FILE_SIZE" value="300000" />
 <div>
 <label for="fileselect">select file</label>
 <input type="file" id="fileselect" name="fileselect[]" multiple="multiple" />
 </div>
 <div >
 <button type="submit">upload</button>
 </div>
 </fieldset>
 </form>

code of upload.php:

 $myFile = $_FILES['fileselect'];
 $fileCount = count($myFile["name"]);
 for ($i = 0; $i < $fileCount; $i++) {
 $target_dir = "uploads/";
 $target_file = $target_dir . basename( $myFile["name"][$i]);
 // echo $myFile["tmp_name"][$i];
 if (move_uploaded_file( $myFile["tmp_name"][$i], $target_file)) {
 echo "The file ". basename( $myFile["name"][$i]). " has been uploaded.";
 } else {
 echo "can not move";
 }
 }

If i upload file type is Image or MP4, they upload ok.

i try var_dump : upload a image.

array(1) { ["fileselect"]=> array(5) { ["name"]=> array(1) { [0]=> string(10) "header.png" } ["type"]=> array(1) { [0]=> string(9) "image/png" } ["tmp_name"]=> array(1) { [0]=> string(24) "C:\xampp\tmp\phpED23.tmp" } ["error"]=> array(1) { [0]=> int(0) } ["size"]=> array(1) { [0]=> int(32416) } } } The file header.png has been uploaded.

Upload a pdf:

array(1) { ["fileselect"]=> array(5) { ["name"]=> array(1) { [0]=> string(15) "Untitled-12.pdf" } ["type"]=> array(1) { [0]=> string(0) "" } ["tmp_name"]=> array(1) { [0]=> string(0) "" } ["error"]=> array(1) { [0]=> int(2) } ["size"]=> array(1) { [0]=> int(0) } } } can not move

But i can't upload file pdf.

Why can't upload file pdf?

• Code Cooker: What actually is the error message are you getting?
• hassan: any errors? and does the pdf file is greater than MAX_FILE_SIZE value ?
• D T: error: echo "khong the move"
• D T: size of file pdf only has 300kb
• RiggsFolly: I suggest you ALWAYS check $myFile["name"][$i]['error'] whenever you do an upload. It will normally show you what the problem is or at least lead you to the solution

Answer 1

First of all there is an issue, check the following line:

<input type="file" id="fileselect" name="fileselect" multiple="multiple" />

input file with multiple selection must have its name as an array so that it can hold multiple files name like:

<input type="file" id="fileselect" name="fileselect[]" multiple="multiple" />

Without this you cannot iterate over all the files.

• D T: thank,i miss when post question. but that is not my problem
• D T: Upload a pdf : array(1) { ["fileselect"]=> array(5) { ["name"]=> array(1) { [0]=> string(15) "Untitled-12.pdf" } ["type"]=> array(1) { [0]=> string(0) "" } ["tmp_name"]=> array(1) { [0]=> string(0) "" } ["error"]=> array(1) { [0]=> int(2) } ["size"]=> array(1) { [0]=> int(0) } } } can not move
