问题
I\'ve been trying to make this work for quite some time now. But I can\'t seem to make it work. I wanted to have a multiple image upload form with only using one input.
this is my upload.php
<?php
include(\"../include/session.php\");
session_start();
$allowedExts = array(\"jpeg\", \"jpg\", \"png\", \"gif\");
$extension = end(explode(\".\", $_FILES[\"upload\"][\"name\"]));
if(isset($_FILES[\'upload\'][\'tmp_name\']))
{
for($i=0; $i < count($_FILES[\'upload\'][\'tmp_name\']);$i++)
{
if (($_FILES[\"upload\"][\"name\"] < 90000000000000000)
&& in_array($extension, $allowedExts)) {
if ($_FILES[\"upload\"][\"error\"] > 0)
{
header(\'location: \'.$error); die;
}
else
{
if (file_exists(\"../icons/\".$_SESSION[\"username\"] .\"/\" . $_FILES[\"upload\"][\"name\"]))
{
echo \"error\";
}
else
{
if(!is_dir(\"../icons/\". $_SESSION[\"username\"] .\"/\")) {
mkdir(\"../icons/\". $_SESSION[\"username\"] .\"/\");
}
$temp = explode(\".\",$_FILES[\"upload\"][\"name\"]);
$file = rand(1,999999999999) . \'.\' .end($temp);
move_uploaded_file($_FILES[\"upload\"][\"tmp_name\"], \"../icons/\". $_SESSION[\"username\"] .\"/\". $file);
}
}
}
} else {
echo \"yep error\";
}
}
}
?>
if i take out the lines
if(isset($_FILES[\'upload\'][\'tmp_name\']))
{
for($i=0; $i < count($_FILES[\'upload\'][\'tmp_name\']);$i++)
{
With the corresponding closing bracket, it seems to work fine. The image is uploaded perfectly. But the thing is, it only allows me to upload one.
Please I really need your expertise. THank you
回答1:
extract($_POST);
$error=array();
$extension=array("jpeg","jpg","png","gif");
foreach($_FILES["files"]["tmp_name"] as $key=>$tmp_name) {
$file_name=$_FILES["files"]["name"][$key];
$file_tmp=$_FILES["files"]["tmp_name"][$key];
$ext=pathinfo($file_name,PATHINFO_EXTENSION);
if(in_array($ext,$extension)) {
if(!file_exists("photo_gallery/".$txtGalleryName."/".$file_name)) {
move_uploaded_file($file_tmp=$_FILES["files"]["tmp_name"][$key],"photo_gallery/".$txtGalleryName."/".$file_name);
}
else {
$filename=basename($file_name,$ext);
$newFileName=$filename.time().".".$ext;
move_uploaded_file($file_tmp=$_FILES["files"]["tmp_name"][$key],"photo_gallery/".$txtGalleryName."/".$newFileName);
}
}
else {
array_push($error,"$file_name, ");
}
}
and you must check your HTML code
<form action="create_photo_gallery.php" method="post" enctype="multipart/form-data">
<table width="100%">
<tr>
<td>Select Photo (one or multiple):</td>
<td><input type="file" name="files[]" multiple/></td>
</tr>
<tr>
<td colspan="2" align="center">Note: Supported image format: .jpeg, .jpg, .png, .gif</td>
</tr>
<tr>
<td colspan="2" align="center"><input type="submit" value="Create Gallery" id="selectedButton"/></td>
</tr>
</table>
</form>

Sample code:

$target_path = "uploads/"; //Declaring Path for uploaded images
for ($i = 0; $i < count($_FILES['file']['name']); $i++) { //loop to get individual element from the array
$validextensions = array("jpeg", "jpg", "png"); //Extensions which are allowed
$ext = explode('.', basename($_FILES['file']['name'][$i])); //explode file name from dot(.)
$file_extension = end($ext); //store extensions in the variable
$target_path = $target_path.md5(uniqid()).
".".$ext[count($ext) - 1]; //set the target path with a new name of image
$j = $j + 1; //increment the number of uploaded images according to the files in array
if (($_FILES["file"]["size"][$i] < 100000) //Approx. 100kb files can be uploaded.
&& in_array($file_extension, $validextensions)) {

$qry="INSERT INTO `eb_re_about_us`(`er_abt_us_id`, `er_cli_id`, `er_cli_abt_info`, `er_cli_abt_img`) VALUES (NULL,'$b1','$b5','$filepath')";
$res = mysql_query($qry,$conn);
if($res)
echo "<br/><br/>Client contact Person Information Details Saved successfully";
//header("location: nextaddclient.php");
//exit();
else
echo "<br/><br/>Client contact Person Information Details not saved successfully";
}
?>
Here $file_name_all And $filepath get 1 uplode file name 2 time?

Multipal image uplode with other taBLE $sql1 = "INSERT INTO event(title) VALUES('$title')";
$result1 = mysqli_query($connection,$sql1) or die(mysqli_error($connection));
$lastid= $connection->insert_id;
foreach ($_FILES["file"]["error"] as $key => $error) {
if ($error == UPLOAD_ERR_OK ){
$name = $lastid.$_FILES['file']['name'][$key];
$target_dir = "photo/";
$sql2 = "INSERT INTO photos(image,eventid) VALUES ('".$target_dir.$name."','".$lastid."')";
$result2 = mysqli_query($connection,$sql2) or die(mysqli_error($connection));
move_uploaded_file($_FILES['file']['tmp_name'][$key],$target_dir.$name);
}
}
And how to fetch
$query = "SELECT * FROM event ";
$result = mysqli_query($connection,$query) or die(mysqli_error());
if($result->num_rows > 0) {
while($r = mysqli_fetch_assoc($result)){
$eventid= $r['id'];
$sqli="select id,image from photos where eventid='".$eventid."'";
$resulti=mysqli_query($connection,$sqli);
$image_json_array = array();
while($row = mysqli_fetch_assoc($resulti)){
$image_id = $row['id'];
$image_name = $row['image'];
$image_json_array[] = array("id"=>$image_id,"name"=>$image_name);
}
$msg1[] = array ("imagelist" => $image_json_array);
}
