在PHP中使用循环获取图像

Question

I have selected multiple image and show the preview in a div box. When I click on Save button, I want to get the information of the image using loop in PHP.

I try to echo the image_path for testing purpose, but it show nothing output.

HTML Form

<form id="photo-event-form" name="event-photo-gallery-form" class="form-horizontal" method="post" role="form" enctype="multipart/form-data">
<fieldset>

   <div class="control-group">                                          
      <label class="control-label" for="event_date">Event Photo</label>
      <div class="controls">
       : <input type="file" class="span3" id="pg_album" name="pg_album" multiple />

          <div id="form_button_div" class="form_button_div">
          <button id="test" name="pg_Save" type="submit" class="btn btn-primary">Save</button> 
          <button class="btn">Cancel</button>
   </div>
</fieldset>
</form>

PHP Save submit

if (isset($_POST['pg_Save'])) {

    $image_path = $_FILES['pg_album'];

    $i = 0;
    foreach ($Contents as $image_path) {
        $i++;
        echo $image_path;  //display image file path
    }
}
?>

In your foreach loop you are overwriting the value of $image_path. So if it had the right value (it doesn't) it is gone before you attempt to use it.

Additionally, you cannot get the file path as it resided on the user's computer. That information is not provided and thus not available to you. If you want to know what information is available to you, read the PHP manual on handling file uploads.
