Uploading multiple image files to php mysql gallery

Question

I am close to 65% close to working in my gallery as I wanted. Can someone please tell me how I can upload multiple images to my gallery? 

Here is the code.

Simple admin form code:

    <form enctype="multipart/form-data" action="uploader.php" method="POST">


        Category: <select class="text" name="dataType[]">
        <option value="treeremoval" selected="selected">treeremoval</option>
        <option value="treetrimming" >treetrimming</option>
        <option value="treebracing" >treebracing</option>
        <option value="stumpgrinding" >stumpgrinding</option>
        <option value="firewood" >firewood</option>
        <option value="cleanup" >cleanup</option>
        </select>
<br /><br />

    Caption: <input type="text" name="title[]">
<br /><br />

Image to upload: <input type="file" name="image[]" />
<br /><br />



        Category: <select class="text" name="dataType[]">
        <option value="treeremoval" selected="selected">treeremoval</option>
        <option value="treetrimming" >treetrimming</option>
        <option value="treebracing" >treebracing</option>
        <option value="stumpgrinding" >stumpgrinding</option>
        <option value="firewood" >firewood</option>
        <option value="cleanup" >cleanup</option>
        </select>
<br /><br />

    Caption: <input type="text" name="title[]">
<br /><br />

Image to upload: <input type="file" name="image[]" />
<br /><br />



    <input type="submit" value="Upload">
</form>

The uploader.php code:

---

    <?php
include($_SERVER['DOCUMENT_ROOT'] . "/connections/dbconnect.php");

$dataType = mysql_real_escape_string($_POST["dataType"][$i]);
$title = mysql_real_escape_string($_POST["title"][$i]);

$fileData = pathinfo(basename($_FILES["image"]["name"][$i]));

$fileName = uniqid() . '.' . $fileData['extension'][$i];

$target_path = ($_SERVER['DOCUMENT_ROOT'] . "/images/gallery/" . $fileName);


for($i=0;$i<count($_FILES["image"]["name"]);$i++){

 $dataType = mysql_real_escape_string($_POST["dataType"][$i]);  // get the dataType with the same key - $i
    $title = mysql_real_escape_string($_POST["title"][$i]);   // get the title with the same key - $i

    $fileData = pathinfo(basename($_FILES["image"]["name"][$i]));
while(file_exists($target_path))
{
    $fileName = uniqid() . '.' . $fileData['extension'];
    $target_path = ($_SERVER['DOCUMENT_ROOT'] . "/images/gallery/" . $fileName);
}

 if (move_uploaded_file($_FILES["image"]["tmp_name"][$i], $target_path))
    {    // The file is in the images/gallery folder. Insert record into database by
    // executing the following query:
     $sql="INSERT INTO images (data_type, title, file_name)"."VALUES('$dataType','$title','$fileName')";
     $retval = mysql_query($sql);



echo "The image {$_FILES['image']['name'][$i]} was successfully uploaded and added to the gallery<br />
     <a href='index.php'>Add another image</a><br />";


}
else
{
 echo "There was an error uploading the file {$_FILES['image']['name'][$i]}, please try again!<br />";
    }
} // close your foreach
?>

I tried duplicating the form code but it didn't help Can someone please help me with this?

Answer 1

Create several file inputs for your form. The use of an array name image[]  is one approach.

Image to upload: <input type="file" name="image[]" /><br />
Image to upload: <input type="file" name="image[]" /><br />
Image to upload: <input type="file" name="image[]" /><br />
....  // as many as you want. Just be aware of upload_max_filesize, memory_limit, post_max_size etc.
<br /> 

Next, include a for loop in your uploader.php file to enclose your file upload code.

for($i=0;$i<count($_FILES["image"]["name"]);$i++){

    $fileData = pathinfo(basename($_FILES["image"]["name"][$i]));

     ...

    if (move_uploaded_file($_FILES["image"]["tmp_name"][$i], $target_path))
    {
      ...

      echo "The image {$_FILES['image']['name'][$i]} was successfully uploaded and added to the gallery<br />";

    }
    else
    {
     echo "There was an error uploading the file {$_FILES['image']['name'][$i]}, please try again!<br />";
    }

 Then Remove the duplicate code above the for a loop. Remove basename(), as this is causing your extension to fail, and pathinfo() will return the ['basename'].
