[SOLVED] Image Display

[graham23s]

Hi Guys,

 

i have made a very basic image shack type script where users can upload photos (within size,height,type limitations) everything works good apart from when i try to display the details the user has just uploaded (because they don't have to register i can't use an id to grab the details from mysq or username for that matter) is there another way i can show the user the image they have just uploaded with out an id

 

code:

 

<?php
     ## submission ######################################################################
     if(isset($_POST['upload'])) {
     ## UPLOAD ABOVE ####################################################################
     
     ## VARIABLES #######################################################################
     $filename_of_original_file = $_FILES['userimage']['name'];
     $type_of_original_file = $_FILES['userimage']['type'];
     $size_of_original_file = $_FILES['userimage']['size'];
     $allowed_image_types = array("image/pjpeg","image/gif","image/bmp");
     $max_image_width = 600;
     $max_image_height = 500;
     $max_image_size = 200000;
     
     ## allowed types ###################################################################
     if (!in_array($_FILES["userimage"]["type"], $allowed_image_types)) {
  
     echo '<br /><font color="red">Error:</font> Sorry, That File Type Isn\'t Allowed Please (<a href="javascript: history.go(-1)">Go Back</a>) And Upload Another One.<br /><br />';
     include("includes/footer.php");
     exit;
    
     }
      
     ## height & width ##################################################################
     $dim = getimagesize($_FILES["userimage"]["tmp_name"]);

     if($dim[0] >= $max_image_width || $dim[1] >= $max_image_height) {
  
     echo "<br /><font color=\"red\">Error:</font> Sorry The Maximum Width Is $max_image_width & Maximum Height Is $max_image_height Please (<a href=\"javascript: history.go(-1)\">Go Back</a>) And Upload Another One.<br /><br />";
     include("includes/footer.php");
     exit;
    
     }
      
     ## size is allowed #################################################################
     if ($_FILES["userimage"]["size"] > $max_image_size) {
       
     echo '<br /><font color="red">Error:</font> Sorry, That File Was To Big To Be Uploaded (3mb Max) Please (<a href="javascript: history.go(-1)">Go Back</a>) And Upload Another One.<br /><br />';
     exit;
   
     } 
     
     ## rename the image ################################################################
     $renamed_image = rand(0000000000, 9999999999).".".strtolower(substr($_FILES['userimage']['name'], -3));

     $uploadpath = "uploads/";
     $uploadpath = $uploadpath.$renamed_image;

     $q2 = "SELECT * FROM `images` 	where `image_name`='$renamed_image'"; 
     $r2 = mysql_query($q2) or die (mysql_error());

     $image_display = $row['image_name'];

I would use sessions in this case. the session id should work to keep the user tied with the image. You would have to attach the session id to the image however you see fit.

 

Not a great answer, but hopefully it helps a little

Hi Mate,

 

thanks for the input i ended up using: mysql_insert_id(); to get the last id inputted into mysl.

cheers
